THE PREFACE.

[i]

THIS being probably the laſt Time I may treſpaſs on the Publick, I look upon myſelf in ſome Meaſure obliged to ſettle my Accounts with the World as an Author, before I make my Exit, by endeavouring to ſhew I have not always offended out of Preſumption, Vanity, or Wantonneſs.

[ii]The firſt Time I adventured in Print, was on the Account of my great Maſter and generous Friend, Dr. Pitcairn. He thought himſelf ill-uſed by ſome of his Brethren of the profeſſion who then were at inteſtine War on the Subject of Fevers; and fancied the handſomeſt Way to bring them down, was to exhibit a more ſpecious Account of this Diſeaſe, than any of them had ſhewn. His Buſineſs then in the Practice of Phyſick was ſo great, as not to allow him ſufficient Time for ſuch a Work. Two others therefore, with myſelf, were joined to manage the Affair: In which he was to cut and carve, and to add the practical Part. My Province was the Theory. I was then very young in the Profeſſion, and living in the Country. But in a few Days I brought in my Part finiſhed, as it now appears, under the Title of [iii] The New Theory of Fevers. The others either ſuppreſs'd or forgot theirs, and mine, without the leaſt Alteration, but in a few Words, was ordered for the Preſs. I could not reſist the Commands of my Friend; but would not ſuffer my Name to be put to it, being conſcious it was a raw and unexperienced Performance. There are tho', ſome Thing sin it which may be of Uſe to Beginners, both as to the Method of philoſophiſing on the animal Oeconomy, and in the Account of the Manner of the Operation of the greater Medicines. The Foundations alſo and the Cauſes aſſigned for acute and ſlow Fevers, I ſtill think ſolid and juſt, and more particular and limited than thoſe of any other Theory yet publiſhed. But it wants ſo much filing and finiſhing, ſo many Alterations and Additions, as would coſt me more Labour and Pains than the writing a new Treatiſe on the [iv] ſame Subject: So that out of mere Lazineſs and Inappetency, I have thrown it by as unripe Fruit, and ſuffered it to be as if it never had been.

My next Sally was in a Book of abſtracted Geometry and Algebra, entitled, Methodus Fluxionum Inverſa, brought forth in Ambition and bred up in Vanity. There are ſome Things in it tolerable for the Time, when the Methods of Quadratures, the Menſuration of Ratio's, and Transformation of Curves, into thoſe of other Kinds, were not advanced to ſuch Heights as they now are. But it is a long Time ſince I was forced to forgoe theſe barren and airy Studies for more ſubſtantial and commodious Speculations: Indulging and Rioting in theſe ſo exquiſitely bewitching Contemplations, being only proper for publick Profeſſors, and thoſe born to Eſtates, and who are under no outward [v] Neceſſities. Beſides, to own a great but grievous Truth, tho' they may quicken and ſharpen the Invention, ſtrengthen and extend the Imagination, improve and refine the reaſoning Faculty, and are of Uſe both in the neceſſary and the luxurious Refinement of mechanical Arts; yet having no Tendency to rectify the Will, ſweeten the Temper, or mend the Heart, they often leave a Stiffneſs, Poſitiveneſs, and Sufficiency on weak Minds, much more pernicious to Society, and the Intereſts of the great End of our Being, than all the Advantages they bring them can recompence. They are indeed Edge-Tools, not to be truſted in the Hands of any, but thoſe who have already acquired an humble Heart, a lowly Spirit, and a ſober and teachable Temper For in others they are very apt to beget a ſecret and refined Pride, an over-weening and over-bearing Vanity (the moſt [vi] oppoſite Temper to the true GoſpelSpirit, which, without Offence, I may ſuppoſe to be the beſt Diſpoſition of Mind) that tempts them to preſume on a Kind of Omniſcience, in Reſpect of their Fellow-Creatures, that have not riſen to their Elevation; and to ſet up for an Infallibility, or at leaſt a deciſive Judgment, even in Matters which do not admit of a more or leſs (their proper Object) of which Kind whatever relates to the infinite Author of our Being most certainly is. Upon all which Accounts, conſcious of my own Weakneſs, I have long ſince bid them an Adieu, farther than as they ſerve to amuſe, or are uſeful in the abſolute Neceſſities of Life.

The Defence of that Book against the learned and acute Mr. Abr. de Moivre, being written in a Spirit of Levity and Reſentment, I most ſincerely [vii] retract, and wiſh undone, ſo far as it is perſonal or peeviſh, and ask him and the World Pardon for it; as I do for the Defence of Dr. Pitcairn's Diſſertations, and the New Theory of Fevers, against the late learned and ingenious Dr. Oliphant. I heartily condemn and detest all perſonal Reflexions, all malicious and unmannerly Turns, and all falſe and unjuſt Repreſentations, as unbecoming Gentlemen, Scholars, and Chriſtians; and diſprove and undo both Performances, as far as in me lies, in every Thing that does not ſtrictly and barely relate to the Argument.

The first Part of the Philoſophical Principles, that of Natural Religion, conſiſts merely of Diſcourſes and Lectures of Natural Philoſophy, and of its Conſequences on Religion, occaſionally read or diſcourſed [viii] to that moſt noble and great Perſon, the Duke of Roxburgh, who is now ſo great an Ornament to his Country, and his high Employments, to whom they were inſcribed. I thought they might be of Uſe to other young Gentlemen, who, while they were learning the Elements of natural Philoſophy, might have thereby the Principles of natural Religion inſenſibly inſtilled into them. And accordingly it has been and is ſtill uſed for that Purpoſe at both Univerſities. Upon which Account, upon proper Occaſions, I will not fail to improve it in all the new Diſcoveries in Experimental Philoſophy, or in the final and natural Cauſes of Things as happen to be made, ſo as to leave it as little imperfect in its Kind as I poſſibly can.

The ſecond Part of the Philoſophical Principles, to wit, that of [ix] Revealed Religion, was added afterward, to ſhew, that all our Knowledge of Nature was by Analogy, or the Relations of Things only, and not their real Nature, Subſtance, or internal Principles: That from this Method of Analogy (the only Medium of humane Knowlege) we ſhould be neceſſarily led, to conclude the Attributes or Qualities of the ſupreme and abſolute Infinite, were indeed analogous to the Properties or Qualities of finite Beings, but only in ſuch a Manner as the Difference between Infinite and Finite requires; and that therefore, not being able to know preciſely theſe Differences, we ought implicitely to believe without reaſoning what is revealed to us concerning the Nature of the infinite Being; or bring our Reaſon to ſubmit to the Myſteries of Faith. How I have ſucceeded is not for me to determine. As the End was honest, I am ſecure the great [x] Principles and the fundamental Propoſitions are true and juſt. They may want a little farther clearing up and Explication: But as yet I have met with no Reaſon to retract any Thing material; elſe I ſhould moſt certainly do it.

The Eſſay on the Gout and Bath Waters was brought forth by mere Accident. The firſt Draught being, as I there mentioned, only a Paper of Directions for a Gentleman, my Friend and Patient, troubled with the Gout. It was enlarged upon different Occaſions, and publiſhed to prevent its being pyrated; ſeveral Copies having been given out to others in the ſame Circumſtances. I have the Satisfaction to know from many different Hands, that it has benefited great Numbers of infirm and afflicted Perſons; and ſhall [xi] therefore go on to cultivate it as far as my poor Abilities will permit.

I am now come to this my last Production; whoſe Origin was as caſual as that of my former. My good and worthy Friend, the preſent Maſter of the Rolls, having been last Autumn at Bath for a Confirmation of his Health, at his Departure deſired of me to draw up ſome Inſtructions in writing to direct him in the Conduct of his Health for the future, and in the Manner of ſupporting his Spirits free and full, under the great Buſineſs he is engaged in. I was then in the Hurry of our Seaſon, and could not ſo ſoon anſwer his Expectation, as his real Worth, and my ſincere Eſteem required. I thought myſelf therefore the more obliged aſſoon as I had Leiſure, to exert myſelf to the uttermost in Obedience to his Commands. At first I drew up most of [xii] theſe Rules at the End of the ſeveral Chapters; but, upon Reflexion, thought it not Reſpect enough to his good Taſte and Capacity to judge of the Reaſons of Things, to preſcribe him bare and dry Directions in Matters of ſo great Moment. I added therefore the philoſophical Account and Reaſons of theſe Rules, which make up the Bulk of the Chapters themſelves. He, out of his Love to his Fellow-Citizens (which is one ſhining Part of his Character, and which I ought to ſuppoſe has in this Inſtance only impoſed on his better Judgment) deſired they might be made publick. Upon which Account ſeveral Things have been ſince added, to make the whole of more general Uſe. If therefore any Thing in this Treatiſe be tolerable, or if any Perſon receive Benefit by it, they owe it entirely to that excellent Perſon, upon whoſe Account [xiii] ſolely it was undertaken, and at whoſe Request it is publiſhed.

I have indeed long and often obſerved, with great Pity and Regret, many very learned, ingenious, and even religious Perſons, who being weak and tender (as ſuch generally are) have ſuffered to the laſt Extremity for Want of a due Regimen of Diet, and other general Directions of Health, who had good Senſe enough to underſtand the Force and Neceſſity of ſuch Rules, valued Health ſufficiently, and deſpiſed ſenſual Gratifications for the Pleaſures of the Mind ſo far, as to be able and willing to abſtain from every Thing hurtful, deny themſelves any Thing their Appetites craved, and to conform to any Rules for a tolerable Degree of Health, Eaſe, and Freedom of Spirits; and yet being ignorant how [xiv] to conduct themſelves, from what to abſtain and what to uſe, they have ſuffered even to mortal Agonies; who, had they been better directed and inſtructed, had paſs'd their Lives in tolerable Eaſe and Quiet. It is for theſe, and theſe only, the following Treatiſe is deſigned. The Robuſt, the Luxurious, the Pot-Companions, the Looſe, and the Abandoned, have here no Buſineſs; their Time is not yet come. But the Sickly and the Aged, the Studious and the Sedentary, Perſons of weak Nerves, and the Gentlemen of the learned Profeſſions, I hope, by the divine Bleſſing on the following Treatiſe, may be enabled to follow their Studies and Profeſſions with greater Security and Application, and yet preſerve their Health and Freedom of Spirits more entire and to a longer Date. I am morally certain, [xv] had I known and been as well ſatisfied of the Neceſſity of the Rules here laid down, thirty Years ago, as I am now, I had ſuffered leſs, and had had a greater Freedom of Spirits than I have enjoy'd. But every Thing is best as it has been, except the Errors and Failings of our free Wills.

I know no uſeful Means of Health and Long Life I have omitted, nor any pernicious Cuſtom I have not noted; and have given the plainest and most familiar Reaſons I could urge for the Rules I have here laid down. Most of my Arguments (as they needs muſt) have riſen out of the animal Functions and Oeconomy: And I have uſed as little Subtilty and Refinement in my Explications of theſe, as the preſent State of Natural Philoſophy could admit. I have been often contented with [xvi] plain and obvious Facts to account for Appearances, and the Cautions thence deduced; when, according to the Humour of the preſent Age, I might have run into refined Speculations of Metaphyſicks, or Mathematicks; being contented with the Craſſo Modo philoſophari; becauſe we ſhall never be able to ſearch out the Works of the Almighty to Perfection, ſo as to penetrate the internal Nature of Things.

I have conſulted nothing but my own Experience and Obſervation on my own crazy Carcaſe and the Infirmities of others I have treated, in the following Rules, their Reaſons and Philoſophy, (ſo that if any Thing is borrowed, it has occurred to me as my own) but in ſo far as Authorities go to ſhorten philoſophical Accounts. Not but that all ſyſtematick Writers in [xvii] Phyſick, and many particular Authors, have treated the ſame Subject: But their Rules, beſides that they are often inconſiſtent with Reaſon, or contrary to Experience, are ſo general, and expreſs'd in ſo unlimited and undefined Terms, as leave little or no Certainty in them; when apply'd to particular Caſes, they want the neceſſary Preciſion and Exactneſs, and ſo became uſeleſs or perplexing: and laſtly, when they come, (which is rarely to be found among them) to give the Reaſons and Philoſophy of their Directions, they have not the Perſpicuity and natural Way of convincing the ingenious, ſickly, and tender Sufferers, ſo neceſſary to make them chearfully and readily undergo ſuch ſevere Reſtraints; which I take to be by far the most difficult Part of ſuch a Work, and which I have laboured with my utmost Power to ſupply.

[xviii]I know not what may be the Fate and Succeſs of this Performance; nor am I ſolicitous about it, being conſcious the Deſign was honest, the Subject weighty, and the Execution the best my Time, my Abilities, and my Health would permit, which cannot bear the Labour of much Fileing and Finiſhing. Being careful not to incroach on the Province of the Phyſician, I have concealed nothing my Knowledge could ſuggest to direct the Sufferer, in the best Manner I could, to preſerve his Health and lengthen out his Life: And I have held out no falſe or deluſory Lights to lead him aſtray, or torment him unneceſſarily.

If it were poſſible any Set of Men could be offended at my Performance, it might be my Brethren of the Profeſſion, [xix] for endeavouring to leſſen the Materia Morbifica. But as this would be the most malicious, unjust, and unworthy Reflexion could be thrown on Scholars and Gentlemen of a liberal Education; ſo I never entertain'd the moſt remote Vanity to think any Endeavour of mine would make ſo conſiderable a Change in the Nation; eſpecially when the Devil, the World, and the Fleſh were on the other Side of the Queſtion, which have ſtood their Ground even against the Rules of Life and Immortality brought to Light by the Goſpel.

I cannot conclude this tedious Preface without begging Pardon of the Reader for troubling him with my private Matters. All I can ſay as an Apology is, that of whatſoever Indifference my Concerns as an Author may [xx] be to him, yet they were not ſo to me; this being the only Place and Time I may have to adjust them in, and it being the Heighth of my Ambition,

‘Nil conſcire mihi, nullâ palleſcere culpâ.’

[]AN ESSAY OF Health and Long Life.

§. 1.

IT is a common Saying, That every Man paſt Forty is either a Fool or a Phyſician: It might have been as juſtly added, that he was a Divine too: For, as the World goes at preſent, there is not any Thing that the Generality of the better Sort of Mankind ſo laviſhly and ſo unconcernedly throw away as Health, except eternal Felicity. Moſt Men know when they [2] are ill, but very few when they are well. And yet it is moſt certain, that 'tis eaſier to preſerve Health than to recover it, and to prevent Diſeaſes than to cure them. Towards the firſt, the Means are moſtly in our own Power: Little elſe is required than to bear and forbear. But towards the latter, the Means are perplexed and uncertain; and for the Knowledge of them the far greateſt Part of Mankind muſt apply to others, of whoſe Skill and Honeſty they are in a great meaſure ignorant, and the Benefit of whoſe Art they can but conditionally and precautiouſly obtain. A crazy Conſtitution, original weak Nerves, dearbought Experience in Things helpful and hurtful, and long Obſervation on the Complaints of others, who came for Relief to this univerſal Infirmary, BATH, have at laſt (in ſome meaſure) taught me ſome of the moſt effectual Means of preſerving Health and prolonging Life in thoſe who are tender and ſickly, and labour under chronical Diſtempers. And I thought I could not ſpend my leiſure Hours better than by putting together the moſt general Rules for that Purpoſe, and ſetting them in the cleareſt and ſtrongeſt Light I could, for the Benefit of thoſe who [3] may want them, and yet have not had ſuch favourable Opportunities to learn them.

§. 2.

And that I might write with ſome Order and Connexion, I have choſen to make ſome Obſervations and Reflections on the Nonnaturals (as they are called, poſſibly becauſe that in their preternatural State they are eminently injurious to human Conſtitutions; or more probably, becauſe tho' they be neceſſary to the Subſiſtence of Man, yet in reſpect of him, they may be conſidered as external, or different from the internal Cauſes that produce Diſeaſes) to wit, 1. The Air we breathe in. 2. Our Meat and Drink. 3. Our Sleep and Watching. 4. Our Exerciſe and Reſt. 5. Our Evacuations and their Obſtructions. 6. The Paſſions of our Minds: And laſtly, to add ſome Obſervations that come not ſo naturally under any of theſe Heads. I ſhall not conſider here how philoſophically theſe Diſtinctions are made; they ſeem to me, the beſt general Heads for bringing in thoſe Obſervations and Reflections I am to make in the following Pages.

§. 3.

[4]

The Reflection is not more common than juſt, That he who lives phyſically muſt live miſerably. The Truth is, too great Nicety and Exactneſs about every minute Circumſtance that may impair our Health, is ſuch a Yoke and Slavery, as no Man of a generous free Spirit would ſubmit to. 'Tis, as a Poet expreſſes it, to die for fear of Dying. And to forbear or give over a juſt, charitable, or even generous Office of Life, from a too ſcrupulous Regard to Health, is unworthy of a Man, much more of a Chriſtian. But then, on the other Hand, to cut off our Days by Intemperance, Indiſcretion, and guilty Paſſions, to live miſerably for the ſake of gratifying a ſweet Tooth, or a brutal Itch; to die Martyrs to our Luxury and Wantonneſs, is equally beneath the Dignity of human Nature, and contrary to the Homage we owe to the Author of our Being. Without ſome Degree of Health, we can neither be agreeable to ourſelves, nor uſeful to our Friends; we can neither reliſh the Bleſſings of divine Providence to us in Life, nor acquit ourſelves of our Duties to our Maker, or our Neighbour. He that wantonly tranſgreſſeth the ſelf-evident [5] Rules of Health, is guilty of a Degree of Self-Murder; and an habitual Perſeverance therein is direct * Suicide, and conſequently, the greateſt Crime he can commit againſt the Author of his Being; as it is ſlighting and deſpiſing the nobleſt Gift he could beſtow upon him, viz. the Means of making himſelf infinitely happy; and alſo as it is a treacherous forſaking the Poſt, wherein his Wiſdom has placed him, and thereby rendering himſelf incapable of anſwering the Deſigns of his Providence over him. The infinitely wiſe Author of Nature has ſo contrived Things, that the moſt remarkable RULES of preſerving LIFE and HEALTH are moral Duties commanded us, ſo truē it is, that Godlineſs has the Promiſes of this Life, as well as that to come.

To avoid all uſeleſs Refinement, I will lay down only a few plain eaſily obſerved Rules, which a Man may readily follow, without any Trouble or Conſtraint.

CHAP. I. Of AIR.

[6]

§. 1.

AIR being one of the moſt neceſſary Things towards the Subſiſtence and Health of all Animals; 'tis a Wonder to me, that here in England, where Luxury and all the Arts of living well, are cultivated even to a Vice, the Choice of Air ſhould be ſo little conſidered.

§. 2.

From Obſervations on Bleeding in Rheumatiſms, and after catching Cold, 'tis evident, that the Air with its different Qualities, can alter and quite vitiate the whole Texture of the Blood and animal Juices: From the Palſies, Vertigoes, Vapours, and other nervous Affections, cauſed by Damps, Mines, and working on ſome Minerals, (particularly Mercury [7] and Antimony) 'tis plain Air ſo and ſo qualified, can relax and obſtruct the whole nervous Syſtem. From the Cholics, Fluxes, Coughs, and Conſumptions, produced by damp, moiſt and nitrous Air, 'tis manifeſt, that it can obſtruct and ſpoil the noble Organs. The Air is attracted and received into our Habit, and mixed with our Fluids every Inſtant of our Lives; ſo that any ill Quality in the Air ſo continually introduced, muſt in Time produce fatal Effects on the animal OEconomy: And therefore it will be of the utmoſt Conſequence to every one, to take Care what kind of Air it is they ſleep and watch, breath and live in, and are perpetually receiving into the moſt intimate Union with the Principles of Life. I ſhall only take Notice of three Conditions of Air.

§. 3.

The firſt is, That when Gentlemen build Seats, they ought never to place them upon any high Hill, very near any great Confluence of Water, in the Neighbourhood of any great Mines, or Beds of Minerals, nor on any ſwamp, marſhy, or moſſy Foundation; but either in a champaign Country, or on the Side of a ſmall Eminence, ſheltered from the North and [8] Eaſt Winds, or upon a light gravelly Soil. The Nature of the Soil will be well known from the Plants and Herbs that grow on it, or rather more ſecurely from the Nature of the Waters that ſpring out of it, which ought always to be ſweet, clear, light, ſoft, and taſtleſs. All high Mountains are damp, as Dr. Halley obſerved at St. Helena, a mountainous Place, where Damps fell ſo perpetually in the Night time, that he was obliged to be every Moment wiping his Glaſſes, in making his Aſtronomical Obſervations. And where the Mountains are high, the Inhabitants of them are forced to ſend their Furniture, in Winter, to the Valley, leſt it ſhould rot. And 'tis common to have it rain or ſnow on Mountains, when the Valleys below are clear, ſcrene and dry. All great Hills are Neſts of Minerals, and Covers (made of the prominent Earth) for Reſervoirs of Rain-Water. The Clouds are but great Fleeces of rarified Water ſailing in the Air, ſometimes not many Yards above the champaign Country; and theſe high Hills intercepting them, they are compreſſed into Dew and Rain, and are perpetually drilling down the Crannies of [9] the Mountains into theſe Baſins. Hence the Origin of Rivers, and freſh Water Springs. Beſides that, theſe mountainous Places, are always expos'd to high, and almoſt perpetual Winds. Where any great Concourſe of Water is, the Air muſt needs be perpetually damp, becauſe the Sun is perpetually ſtraining from theſe Waters, moiſt Dews and Vapours thro' it. All great Neſts of Minerals, or large Mines, muſt neceſſarily impregnate the Air, with their reſpective Qualities. And moſſy Blackneſs, is ſome Degree of Putrefaction, as *Sir Iſaac Newton obſerves.

§ 4.

Secondly, the Winds that are moſt frequent, and moſt pernicious in England, are the Eaſterly, eſpecially the North Eaſt Winds, which in the Winter are the moſt piercing cold, in Summer the moſt parching hot. In Winter they bring along with them, all the Nitre of the Northern and Scythian Snows, Mountains of Ice, and frozen Seas thro' which they come; and in [10] Summer, blow with all the fiery Particles of the perpetual Day they paſs thro'. From the end of January, till towards the end of May, the Wind blows almoſt perpetually, from the Eaſtern and Northern Points, if the Spring is dry; and from the Southern and Weſtern Points, if the Spring is wet, (and generally from the ſetting in of the Winds, on a NewMoon, you may predict the Weather of the Spring) and our Bodies moſt certainly attracting, the circumambient Air, and the Fumes of thoſe Bodies that are next to us, it will be very convenient for valetudinary, ſtudious, and contemplative Perſons, in a dry Spring, or in Eaſterly Winds, to change their Bedchambers into Rooms that have Weſtern or Southern Lights, or to ſhut cloſe up the Eaſtern and Northern Lights, or to have them but ſeldom opened; and in wet Seaſons, to take the contrary Courſe. And if any ſuch Perſon, has been much expoſed, or long abroad, in a Northerly or bleakiſh Eaſterly Wind, it will be very proper for him to drink down, going to Bed, a large Draught of warm Water-gruel, or of warm ſmall Mountainwine Whey, as an Antidote againſt the [11] nitrous Effluvia, ſuck'd into the Body, and to open the Obſtructions of the Perſpiration made thereby.

§. 5.

Thirdly, from the beginning of November till towards the beginning of February, London is cover'd over with one univerſal nitrous and ſulphurous Smoak, from the Multitude of Coal Fires, the Abſence of that material Divinity the Sun, and the Conſequence thereof, the falling of the Dews, and Vapours of the Night. In ſuch a Seaſon, weak and tender People, and thoſe that are ſubject to nervous or pulmonick Diſtempers, ought either to go into the Country, or to be at home ſoon after Sun-ſet, and to diſpel the Damps with clear, warm Fires, and chearful Converſation, go early to Bed, and riſe proportionally ſooner in the Morning; for, as the Sun's Removal ſuffers the Vapours to fall and condenſe, in the Evening, ſo his Approach diſpels and raiſes them in the Morning. I need not add, that it will be very fit, for thoſe that are valetudinary, to have their Servants, Children, Bedfellows, and all thoſe that approach them, with whom they live conſtantly [12] and mix Atmoſpheres, to be as healthy, ſound and ſweet as poſſibly they can; and, for their own ſakes, to have them remov'd till they are made ſo, if they are otherwiſe. Nor ſhall I add any preſſing inſtances, to avoid wet Rooms, damp Beds, and foul Linnen, or to remove Ordure and Nuſances; the Luxury of England having run all theſe rather into a Vice.

§. 6.

The Air is a Fluid, wherein Parts of all Kinds of Bodies ſwim as in Water. But Air differs from Water in this, that the firſt is compreſſible into a leſſer Compaſs, and ſmaller Volume, like a Fleece of Wool, either by its own Weight, or any other Force, which Weight or Force being removed, the Air immediately recovers its former Bulk and Dimenſions again, whereas no Force whatever can bring Water into narrower Bounds; that is, Air is extreamly elaſtick and ſpringy, but Water is not at all ſo. Yet the Parts of Air would ſeem to be groſſer than the Parts of Water: For Water will get through a Bladder, and may be forced through the Pores of Gold; but Air will paſs through neither. By this its elaſtick Force, the Air inſinuates [13] itſelf into the patent Cavities of all animal Bodies; and the Infant, which never breathed before, aſſoon as it is expoſed to this Element, has the little Bladders, whereof the Lungs conſiſt, blown up into a perpendicular Erection on the Branches of the Wind-pipe; whereby the Obſtruction, from the Preſſure of theſe Veſicles (ariſing from their being compreſſed together, and lying upon one another) being in ſome Meaſure taken off, the muſcular Action of the right Ventricle of the Heart is able to force the Blood through the Lungs into the left Ventricle. But theſe little Bladders, being thus inflated by an elaſtick Fluid, ſtill preſs ſo far upon, and grind the groſſer Particles of the Blood into more ſizeable ones, that they may become ſmall enough to circulate through the other capillary Veſſels of the Body. This elaſtick Air, preſſing equally every Way round, by its Weight and Spring, ſhuts cloſe the Scales of the Scarf-skin of healthy and ſtrong Perſons; ſo that it denies all Entrance to the nitrous and watry Mixture, contained in it, and thus becomes a Kind of Cold Bath, to them, and defends them from catching Cold: But in ſickly, ſtudious, and ſedentary People, [14] and thoſe of weak Nerves, where the Spring of the Coverlets and Scales, that defend the Mouths of the perſpiratory Ducts is weak, the Perſpiration little or next to none at all, and the Blood poor and ſizey; the nitrous and watry Particles of the Air get a ready and free Entrance, by theſe Ducts into the Blood, and by breaking the Globules thereof, coagulating and fixing its Fluidity, quite ſtop the Perſpiration, and obſtruct all the capillary Veſſels, the cutaneous Glands, and thoſe of the Lungs and alimentary Paſſages, when ſuch Bodies are long expoſed to ſuch an Air: And thus begets all theſe Diſorders in the Body, that Air thus and thus poiſoned, was ſhewn capable to produce. So long as the Perſpiration is ſtrong, brisk, and full, 'tis impoſſible any of theſe Diſorders ſhould happen; becauſe the Force of the perſpiratory Steams outward, is greater than the Force whereby theſe noxious Mixtures enter; unleſs the Body be indiſcreetly too long expoſed, or the Action of the nitrous and watry Mixtures be extremely violent. Hence it comes to paſs, that thoſe who are very ſtrong and healthy, and thoſe who have drank ſtrong Liquors ſo plentifully, as to have thereby a brisk [15] Circulation and full Perſpiration, ſeldom or never catch Cold. And this is the Reaſon why rich Foods and generous Wines, moderately uſed, become ſo excellent an Antidote in infectious and epidemick Diſtempers; not only as they baniſh Fear and Terror, but as they make ſo full and free a Stream of Perſpiration, and maintain ſo active and brisk an Atmoſphere, as ſuffers no noxious Steams or Mixtures in the Air to come within it; but drives and beats off the Enemy to a Diſtance. But Perſons of viſcous, heavy Fluids, of poor and ſizey Juices, of little or no Perſpiration, ſuch as generally all ſtudious, ſedentary and ſickly Perſons are, but eſpecially thoſe that are ſubject to nervous Diſorders, muſt neceſſarily ſuffer under theſe poiſonous Mixtures in the Air, if they do not cautiouſly and carefully fence againſt them, or take not a preſent Remedy and Antidote, when tainted. For beſides the Air that gets through the perſpiratory Ducts into the Blood, whenever we Eat, Drink, or Breath, we are taking into our Bodies, ſuch Air as is about us. And when the concoctive Powers are weak, as in ſuch Perſons, and the Quantity of the Food is too great, or its Quality too ſtrong for [16] them, the Chyle is too groſs, and the perſpiratory Matter is ſtopped, becauſe too large for theſe ſmall Ducts; and this whole Maſs, which in common Health is more than double of the groſs Evacuations, recoils in upon the Bowels, and becomes, as it were, Spears, and Darts, and Armour to the Air received from without; which being thus ſharpened with the Salts of the unconcocted Food, together with its own elaſtick Force, pierces the Sides of the Veſſels, and gets into all the Cavities of the Body, and between the Muſcles and their Membranes, and there, in Time, brings forth hypochondriack, hyſterick, nervous, and vapouriſh Diſorders, and all that black Train of Evils ſuch Conſtitutions ſuffer under.

I ſhall now draw out the Cautions here inculcated into a few general Rules.

General Rules for Health and Long Life, drawn from the Head. Of AIR.

[17]
  • 1. THE healthieſt Situation for a Seat is in a champaign Country, or on the Side of a ſmall Eminence, on a gravelly Soil, with a Southern or Weſtern Expoſition, ſheltered from the North and Eaſt Winds, diſtant from any great Concourſe of Waters, or any great Mines or Beds of Minerals, where the Water is ſweet, clear, light, ſoft, and taſtleſs.
  • 2. Tender People on the ſetting in of Eaſterly and Northerly Winds, ought to change their Bed-Rooms for others of Weſterly and Southerly Lights, and the contrary in wet Seaſons.
  • 3. Thoſe who have been much expoſed to, or long abroad in Eaſterly or Northerly Winds, ſhould drink ſome thin and warm Liquor going to Bed.
  • 4. When the dark, dull, foggy Weather laſts at London in Winter, tender [18] People, and thoſe of weak Nerves and Lungs, ought either to go into the Country, or keep much at Home in warm Rooms, go early to Bed, and riſe betimes.
  • 5. Valetudinary People ought to have their Servants, Children, and Bedfellows, or thoſe they continually approach and converſe with, ſound, ſweet, and healthy, or ought to remove them 'till they are ſo, if they are otherwiſe.
  • 6. Every one, in order to pteſerve their Health, ought to obſerve all the Cleanneſs and Sweetneſs in their Houſes, Cloaths, and Furniture, ſuitable to their Condition.

CHAP. II. Of MEAT and DRINK.

[19]

§. 1.

TO have our Food, that is, our Meat and Drink, as to Quantity and Quality duly regulated, and preciſely adjuſted to our concoctive Powers, would be of the utmoſt Conſequence to Health and Long Life. Our Bodies require only a determinate Quantity thereof, to ſupply the Expences of living: and a juſt Proportion of that to theſe would very probably preſerve us from acute, moſt certainly from chronical Diſtempers, and enable us to live, without much Sickneſs and Pain, ſo long as our Conſtitutions were originally made to laſt. The Sources of chronical Diſtempers are firſt Viſcidity in the Juices, or the Overlargeneſs of their conſtituent Particles, which not being ſufficiently broken by the concoctive Powers, ſtop or retard the Circulation; or, ſecondly, too great abundance of ſharp and acrimonious Salts, [20] whereby the Juices themſelves are rendered ſo corroſive, as to burſt or wear out the Solids; or, thirdly, a Relaxation, or Want of a due Force and Springineſs, in the Solids themſelves. An Exceſs in Quantity begets the firſt, the ill Condition of our Meat and Drink the ſecond, and both together, with Want of due Labour, the third.

§. 2.

The Meat of England is generally animal Subſtances. The Animals themſelves, from epidemick Cauſes, bad Food, Age, or other Infirmities, have their Diſeaſes as well as human Creatures: and theſe diſeaſed Animals can never be proper or ſound Food for Men. Adult Animals abound more in urinous Salts than young ones: Their Parts are more cloſely compacted, becauſe more forcibly united; and ſo harder of Digeſtion. 'Tis true, the great Diſtinction of the Fitneſs or Unfitneſs of the ſeveral Sorts of Animals and Vegetables for human Food, depends upon their original Make, Frame, and Nature (and that can be found out only by Experience) as alſo upon the ſpecial Taſte, Complexion, Temperament, and Habits of the Perſon that feeds on them. But by the Help of theſe [21] Three Principles, viz. Firſt, That the Strength or Weakneſs of Coheſion of the Particles of fluid Bodies, depends upon their Bigneſs or Smallneſs; that is, the biggeſt Particles cohere more firmly, than the ſmaller, becauſe more Parts come into Contact in large Bodies than ſmall, and ſo their Union is greater. Secondly, That the greater the Force [Momentum] is, with which two Bodies meet, the ſtronger is their Coheſion, and the more difficult their Separation. Thirdly, that Salts, being comprehended by plain Surfaces, being hard, and in all Changes recovering their Figure, unite the moſt firmly of any Bodies whatſoever: Their plain Surfaces bring many Points into Contact and Union: Their Hardneſs and conſtant Figure make them durable and unalterable; and thereby the active Principles, and the Origin of the Qualities of Bodies; and when they approach within the Sphere of one another's Activity, they firmly unite in Cluſters; all which make the Separation of their original Particles the more difficult. I ſay, from theſe three Principles, we may in general compare the Eaſineſs or Difficulty of digeſting (that is, breaking into ſmall Parts) the ſeveral Sorts of Vegetables [22] and Animals, one with another; and ſo diſcover their Fitneſs or Unfitneſs for becoming Food for tender and valetudinary Perſons.

  • 1. All other Things being ſuppoſed equal, thoſe Vegetables and Animals, that come to Maturity the ſooneſt, are lighteſt of Digeſtion. Thus the Spring Vegetables, as Aſparagus, Straw-berries, and ſome Sorts of Sallading, are more eaſily digeſted than Pears, Apples, Peaches, and Nectarines; becauſe they have leſs of the ſolar Fire in them; their Parts are united by a weaker Heat; that is, with leſs Velocity, and abound leſs in, nay ſcarce have any ſtrong and fixed Salts. Among the Animals, the common Poultry, Hares, Sheep, Kids, Rabbets, &c. who in the ſame, or a few Years come to their Maturity (that is, to propagate their Species) are much more tender and readily digeſted than Cows, Horſes, or Aſſes, (were theſe laſt in uſe for Food, as they have been in Famine) &c. for the Reaſon already given, becauſe their Parts cohere leſs firmly. And it is obſervable, of the Vegetables, which are longeſt a ripening, that is, whoſe Juices have moſt of the ſolar Rays [23] in them, that their fermented Juices yield the ſtrongeſt vinous Spirits; as Grapes, Elder-berries, and the like: and of the Animals that are longeſt in coming to Maturity, that their Juices yield the moſt rank and moſt foetid urinous Salts.
  • 2. Other Things ſuppoſed equal, the larger and bigger the Vegetable or Animal is, in its Kind, the ſtronger and the harder to digeſt is the Food made thereof. Thus a large Onion, Apple, or Pear, and large Beef and Mutton are harder to digeſt than the leſſer ones, of the ſame Kind; not only, as their Veſſels being ſtronger and more elaſtick, their Parts are brought together with a greater Force; but alſo, becauſe the Qualities are proportionably more intenſe in great Bodies of the ſame Kind: Thus, other Things being equal, a greater Fire is proportionably more intenſely hot, than a leſſer one; and the Wine contained in a larger Veſſel becomes ſtronger than that contained in a leſſer; and conſequently the Juices of larger Animals and Vegetables are more rank than the Juices of ſmaller ones of the ſame Kind.
  • [24]3. Other Things being equal, The proper Food appointed for Animals by Nature, is eaſier digeſted than the Animals themſelves; thoſe Animals that live on Vegetables, than thoſe that live on Animals; thoſe that live on Vegetables or Animals, that ſooneſt come to Maturity, than thoſe that live on ſuch as are longer a ripening. Thus Milk and Eggs are lighter of Digeſtion than the Fleſh of Beaſts or Birds; Pullets and Turkies, than Ducks and Geeſe; and Partridge, and Pheaſant are lighter than Woodcock or Snipe; becauſe theſe laſt, being long-billed, ſuck only animal Juices; and for the Reaſons already given, Graſs Beef and Mutton are lighter than ſtall-fed Oxen and Sheep.
  • 4. All Things elſe being alike, Fiſh and Sea-Animals are harder to digeſt than Land-Animals; becauſe univerſally their Food is other Animals, and the Salt Element in which they live compacts their Parts more firmly; Salts having a ſtronger Power of Coheſion than other Bodies. And for the ſame Reaſon, Salt Water Fiſh is harder to digeſt than freſh Water. Thus the Sea Tortoiſe is harder [25] to digeſt than the Land Tortoiſe; and Sturgeon and Turbit, than Trout or Perch.
  • 5. Other Things being equal, Vegetables and Animals that abound in an oily, fat, and glutinous Subſtance, are harder to digeſt, than thoſe of a dry, fleſhy, fibrous Subſtance; becauſe oily and fat Subſtances clude the Force and Action of the concoctive Powers; and their Parts attract one another, and unite more ſtrongly than other Subſtances do, (except Salts) as Sir Iſaac Newton * obſerves. Their Softneſs and Humidity relaxes and weakens the Force of the Stomach, and the Fat and Oil itſelf is ſhut up in little Bladders, that are with Difficulty broken. Thus Nuts of all kinds paſs through the Guts, almoſt untouched: Olives are harder to digeſt than Peaſe; fat fleſh Meat, than the lean of the ſame. Carp, Tench, Salmon, Eel, and Turbit, are much harder to digeſt than Whiting, Perch, Trout, or Haddock.
  • 6. Vegetables and Animals, all Things elſe being alike, whoſe Subſtance is white, [26] or inclining to the lighter Colours, are lighter to digeſt, than thoſe whoſe Subſtance is redder, browner, or inclining towards the more flaming Colours; not only becauſe the Parts that reflect white, and the lighter Colours are leſſer in Bulk than thoſe that reflect the more flaming Colours; but alſo becauſe thoſe of the more flaming Colours abound more with urinious Salts. Thus Turnips, Parſnips, and Potatoes, are lighter than Carrots, Skirrets, and Beet-Raves. Pullet, Turkey, Pheaſant, and Rabbet, are lighter than Duck, Geeſe, Woodcock, and Snipe. Whiting, Flounder, Perch, and Soal, are lighter than Salmon, Sturgeon, Herring, and Mackarel. Veal and Lamb is lighter than Red or Fallow Deer.
  • 7. Laſtly, All other Things being equal, Vegetables and Animals of a ſtrong, poignant, aromatick and hot Taſte, are harder to digeſt than thoſe of a milder, ſofter, and more inſipid Taſte. High Reliſh comes from abundance of Salts: Abundance of Salts ſuppoſes adult Animals, and ſuch as are long a coming to [27] Maturity; and where Salts abound, the Parts are more difficultly ſeparated, and harder to be digeſted. Strong and aromatick Plants imbibe and retain moſt of the ſolar Rays, and become ſolid Spirits, or fixed Flames. And they that deal much in them ſwallow ſo much liveCoals, which will at laſt inflame the Fluids and burn up the Solids.

§. 3.

There is nothing more certain, than that the greater Superiority the concoctive Powers have, over the Food, or the ſtronger the concoctive Powers are, in regard of the Things to be concocted; the finer the Chyle will be, the Circulation the more free, and the Spirits more lightſome; that is, the better will the Health be. Now from theſe general Propoſitions, taking in their own particular Complexion and Habits, valetudinary, ſtudious, or contemplative Perſons may eaſily fix upon theſe particular vegetable or animal Foods, that are fitteſt for them. And if any Error ſhould be committed, 'tis beſt to err on the ſafeſt Side, and rather chuſe thoſe Things that are under our concoctive Powers, than thoſe that are above them. And in the Choice of Animals for our Food, we [28] muſt not paſs over the Manner of fattening and fitting them up for the Table. About London we can ſcarce have any, but cramm'd Poultry, or ſtall-fed Butchery Meat. It were ſufficient to diſguſt the ſtouteſt Stomach, to ſee the foul, groſs, and naſty Manner, in which, and the fetid, putrid and unwholeſome Materials, with which they are fed. Perpetual Foulneſs and Cramming, groſs Food and Naſtineſs, we know, will putrify the Juices and mortify the muſcular Subſtance of human Creatures; and ſure they can do no leſs in Brute Animals, and thus make even our Food Poiſon. The ſame may be ſaid of hot Beds, and forcing Plants and Vegetables. The only Way of having ſound and healthful animal Food, is to leave them to their own natural Liberty, in the free Air, and their own proper Element, with Plenty of Food, and due Cleanneſs, and a Shelter from the Injuries of the Weather, when they have a Mind to retire to it. I add nothing about Cookery: Plain Roaſting and Boiling is as high, as valetudinary, tender, ſtudious, and contemplative Perſons, or thoſe who would preſerve their Health, and lengthen out their Days, ought to preſume on. Made Diſhes, rich [29] Soop, high Sauces, Baking, Smoaking, Salting, and Pickling, are the Inventions of Luxury, to force an unnatural Appetite, and encreaſe the Load, which Nature, without Incentives from ill Habits, and a vicious Palate, will of itſelf make more than ſufficient for Health and long Life. Abſtinence and proper Evacuations, due Labour and Exerciſe, will always recover a decayed Appetite, ſo long as there is any Strength and Fund in Nature to go upon. And 'tis ſcarce allowble to provoke an Appetite, with medicinal Helps, but where the digeſtive Faculties have been ſpoiled and ruined by acute or tedious chronical Diſtempers. And as ſoon as 'tis recovered to any tolerable Degree, Nature is to be left to its own Work, without any Spurs from Cookery or Phyſick.

§. 4.

The next Conſideration is the Quantity of Food that is neceſſary to ſupport Nature, without overloading it, in a due Plight: That is indeed various, according to the Age, Sex, Nature, Strength, and Country the Party is of, and the Exerciſe he uſes. In theſe Northern Countries, the Coldneſs of the Air, the Strength and large Stature of [30] People, demand larger Supplies than in the Eaſtern and warmer Countries. Young growing Perſons, and thoſe of great Strength and large Stature, require more than the Aged, Weak, and Slender. But Perſons of all Sorts will live more healthy and longer by univerſal Temperance, than otherwiſe. And ſome general Obſervations on the Quantity Perſons of different Nations and Conditions, have lived on, healthy, and to a great Age, may give ſome Aſſiſtance to valetudinary and tender Perſons, to adjuſt the due Quantity neceſſary for them.

§ 5.

It is ſurpriſing, to what a great Age the eaſtern Chriſtians, who retir'd from the Perſecutions into the Deſarts of Egypt and Arabia, lived healthful on a very little Food. We are inform'd by Caſſian, that the common Meaſure in twenty four Hours, was about twelve Ounces or a Pound, (for the eaſtern Pound was but twelve Ounces) with mere Element for Drink. St. Anthony liv'd to 105 Years, on mere Bread and Water, adding only a few Herbs at laſt. James the Hermit, to 104. Arſenius, the Tutor of the Emperor Arcadius, to 120: 65 in the world, and 55 in [31] the Deſart. St. Epiphanus, to 115. St. Jerome, to about 100. Simeon Stylites, 109. And Romualdus, 120. And Lewis Cornaro, a Venetian Nobleman, after he had uſed all other Remedies in vain, ſo that his Life was deſpair'd of at 40, yet recover'd and liv'd, by the mere Force of his Temperance, near to 100 years.

§ 6.

Our Northern Climate, as I ſaid from the Purity and Coldneſs of the Air, which bracing the Fibres, makes the Appetite keener, and the Action of Digeſtition ſtronger; and from the Labour and Strength of the People, which makes the Expences of living more, will neceſſarily require a greater Quantity of Food. Yet 'tis wonderful in what Sprightlineſs, Stength, Activity, and fredom of Spirits, a low Diet, even here, will preſerve thoſe that have habituated themſelves to it. Buchanan informs us, of one Laurence who preſerved himſelf to 140, by the mere Force of Temperance and Labour. Spotſwood mentions one Kentigern (afterwards called St. Mongah, or Mungo, from whom the Famous Well in Wales is named) who lived to 185 Years, tho' after he came to the Years of Underſtanding, he never taſted [32] Wine nor ſtrong Drink; and ſlept on the cold Ground. My worthy Friend Mr. Web, is ſtill alive. He by the Quickneſs of the Faculties of the Mind, and the Activity of the Organs of his Body, ſhews the great Benefit of a low Diet, living altogether on vegetable Food and pure Element. The Hiſtory of the Milk * Doctor of Croydon, who by living on Milk only, cured himſelf of an otherwiſe incurable Diſtemper, viz. the Epilepſy, and liv'd in perfect Health for ſixteen Years after, till an Accident cut him off, I have already narrated in my Treatiſe of the Gout. Henry Jenkins a Fiſherman, liv'd 169 Years, his Diet was coarſe and ſower, as his Hiſtorian informs us, that is, plain and cooling, and the Air where he lived ſharp and clear, viz. Allerton upon Swale in Yorkſhire. Parr died ſixteen Years younger, viz. at the age of 152 Years, 9 Months; his Diet was old Cheeſe, Milk, coarſe Bread, ſmall Beer, and Whey: And his Hiſtorian tells us, he might have lived a good while longer, if he had not changed his Diet and Air, coming out of a clear, thin, free Air, into the thick Air of London, and after a conſtant, plain, [33] and homely country Diet, being taken into a ſpendid Family, where he fed high, and drank plentifully of the beſt Wines, whereby the natural Functions of the Parts were overcharged, and the Habit of the whole Body quite diſordered; upon which there could not but ſoon enſue a Diſſolution. *Dr. Liſter mentions eight Perſons in the North of England, the youngeſt of which was above 100 Years, and the eldeſt 140. He ſays, 'tis to be obſerved, that the Food of all this mountainous Country is exceedingly coarſe. And certainly there is no Place in the World more likely to lengthen out Life than England, eſpecially thoſe Parts of it, that have a free open Air, and a gravelly and chalky Soil, if to due Exerciſe, Abſtemiouſneſs, and a plain ſimple Diet were added.

§. 7.

I have elſewhere offered to determine the Quantity of Food, ſufficient to keep a Man of an Ordinary Stature, following no laborious Employment, [34] in due Plight, Health, and Vigour; to wit, 8 Ounces of Fleſh Meat, 12 of Bread, or vegetable Food, and about a Pint of Wine, or other generous Liquor in 24 Hours. But the Valetudinary, and thoſe employed in ſedentary Profeſſions, or intellectual Studies, muſt leſſen this Quantity, if they would preſerve their Health, and the Freedom of their Spirits long. Studious and ſedentary Men muſt of Neceſſity eat and drink a great deal leſs, than thoſe very ſame Men might do, were they engaged in an active Life. For as they want that Exerciſe that is neceſſary towards Concoction and Perſpiration, and that their Nerves are more worn out by intellectual Studies, than even bodily Labour would waſte them; if, in any wiſe, they indulge Freedom of Living, their Juices muſt neceſſarily become viſcid, and their Stomachs relaxed. He that would have a clear Head muſt have a clean Stomach. The Neglect of which is the Cauſe, why we ſee ſo many hypochondriacal, melancholy, and vapouriſh Gentlemen, among thoſe of the long Robe; the only Remedy of which is Labour and Abſtinence.

§. 8.

[35]

Moſt of all the chronical Diſeaſes, the Infirmities of old Age, and the ſhort Periods of the Lives of Engliſhmen, are owing to Repletion. This is evident from hence; becauſe Evacuation of one Kind or another is nine Parts of ten in their Remedy: For not only Cupping, Bleeding, Bliſtering, Iſſues, Purging, Vomiting, and Sweating, are manifeſt Evacuations, or Drains to draw out what has been ſuperfluouſly taken down; but even Abſtinence, Exerciſe, Alteratives, Cordials, Bitters, and Alexipharmicks, are but ſeveral means to diſpoſe the groſs Humours to be more readily evacuated by inſenſible Perſpiration; that new and well concocted Chyle, and ſweet comminuted Juices, may take their Place to reſtore the Habit. And therefore it were much more eaſy, as well as more ſafe and effectual, to prevent than incur the Neceſſity of ſuch Evacuations. And any one may loſe a Pound of Blood, take a Purge, or a Sweat; by dropping the great Meal, or abſtaining from animal Food and ſtrong Liquors, for four or five Days (in chronical Caſes) as effectually as by opening a Vein, ſwallowing a Doſe of Pills, or taking a ſudorifick Bolus.

§. 9.

[36]

I adviſe therefore all Gentlemen of a ſedentary Life, and of learned Profeſſions, to uſe as much Abſtinence as poſſibly they can, conſiſtent with the Preſervation of their Strength and Freedom of Spirits: Which ought to be done as ſoon as they find any Heavineſs, Inquietudes, reſtleſs Nights, or Averſion to Application; either by leſſening one half of their uſual Quantity of animal Food and ſtrong Liqours, 'till ſuch Time as they regain their wonted Freedom and Indolence; or by living a due Time wholly upon vegetable Diet, ſuch as Sago, Rice, Pudding, and the like, and drinking only a little Wine and Water. And if they would preſerve their Health and Conſtitution, and lengthen out their Days; they muſt either inviolably live low (or maigre, as the French call it) a Day or two in the Week; or once a Week, Fortnight, or Month at fartheſt, take ſome domeſtick Purge, which ſhall require neither Diet, nor keeping at Home; but may at once ſtrengthen the Bowels, and diſcharge ſuperfluous Humours. Of this Kind are a Doſe (6 or 7) of the Scotch Pills; half a Dram of the Pilulae Stomachicae cum Gummi, with three or four [37] Grains of Diagryd, mixt; half a Dram of the Pilulae Ruffi; two Ounces of Hiera Piera, with one Dram of the Syrup of Buckthorn; two or three Ounces of Elixir Salutis; or (what I prefer before all theſe) this Preparation of Rhubarb:

Take the beſt Rhubarb in Powder two Ounces and a half; Salt of Wormwood a Dram; Orange Peel half an Ounce; grated Nutmeg two Scruples; Cochineal, half a Dram. Infuſc 48 Hours by a warm Fire-ſide, in a Quart of true Arrack. Strain it off, and put it in a well corked Bottle for Uſe.

Of this two or three Spoonfuls may be taken, two or three Times a Week, or at Pleaſure, with great Safety and Benefit, without Interruption of Buſineſs, or Studies, and continued even to mature old Age, if found neceſſary. So true is old Verulam's Aphoriſm: * Nihil magis conducit ad Sanitatem & Longaevitatem [38] quam crebrae & domeſticae purgationes. And the Gentlemen of the long Robe, thoſe of learned Profeſſions and contemplative Studies, muſt of Neceſſity at laſt take Sir Charles Scarborough's Advice, as 'tis ſaid, to the Dutcheſs of Portſmouth: You muſt eat leſs, or uſe more Exerciſe, or take Phyſick, or be ſick.

§. 10.

Thoſe who have written about Health have given many Rules, whereby to know when any Perſon has exceeded at a Meal: I think, there needs but this ſhort one, which is; If any Man has eat or drank ſo much, as renders him unfit for the Duties and Studies of his Profeſſion (after an Hour's ſitting quiet to carry on the Digeſtion;) he has overdone. I mean only of thoſe of learned Profeſſions and ſtudious Lives; for thoſe of mechanical Employments muſt take the Body, the other Part of the compound, into Conſideration. If tender People, and thoſe of learned Profeſſions would go by this Rule, there would be little Uſe for Phyſick or Phyſicians in chronical Caſes. Or if they would but eat only one Part of animal Food, at the great Meal, and make the other two of vegetable Food; and drink only Water [39] with a Spoonful of Wine, or clear ſmall Beer; their Appetites would be a ſufficient Rule to determine the Quantity of their Meat and Drink. But Variety of Diſhes, the luxurious Artfulneſs of Cookery, and ſwallowing rich Wine after every Bit of Meat, ſo lengthen out the Appetite; the Fondneſs of Mothers, and the Cramming of Nurſes have ſo ſtretched the Capacities of Receiving, that there is no Security from the Appetite among the better Sort. 'Tis amazing to think how Men of Voluptuouſneſs, Lazineſs, and poor Conſtitutions, ſhould imagine themſelves able to carry off Loads of high-ſeaſoned Foods, and inflammatory Liquors, without Injury or Pain; when Men of mechanick Employments, and rubuſt Conſtitutions, are ſcarcely able to live healthy and in Vigour to any great Age, on a ſimple, low, and almoſt vegetable Diet.

§. 11.

Since then our Appetites are deceitful, and Weight and Meaſure troubleſome and ſingular; we muſt have Recourſe to a Rule independent of our Senſations, and free from unneceſſary Trouble and Pain. To anſwer which, I know nothing but Eating and Drinking by our [40] Eye. that is, determining firſt of all either by Weight or Meaſure, or by particular Obſervation or Experiment, the Bulk, or Number of Mouthfuls of Fleſh Meat, and the Number of Glaſſes of ſtrong Liquors, under which we are beſt; and then by our Eye determining an equal Quantity at all Times for the future: Thus the two Wings of a middling Pullet, or one Wing and both Legs; three Ribs of a middling Neck of Mutton, two middling Slices of a Leg or Shoulder, throwing away the Fat and the Skin; ſomewhat leſs of Beef, may be ſufficient for Fleſh Meat, at the great Meal. For we are ſo wiſely contrived, that our Food need not be adjuſted to mathematical Points: A little over or under will make no Difference in our Health. As for Pork, and all Kinds of Hog's Fleſh, I think they ought to be forbidden valetudinary and ſtudious People, as they were the Jews: They feed the fouleſt of any Creature, and their Juices are the rankeſt; their Subſtance the moſt ſurfeiting, and they are the moſt ſubject to cutaneous Diſeaſes and Putrefaction, of any Creature; inſomuch, that in the Time of a Plague, or any epidemical Diſtemper, they are univerſally deſtroyed [41] by all wiſe Nations, as the Southern People do mad Dogs in the hot Months. The ſame Cenſure I ſhould pàſs upon all Fiſh. Moſt Fiſh live in a ſaltiſh Element, and come only into freſh Water Rivers, for the Quietneſs and Conveniency of bringing forth their young ones. This makes their Parts more cloſely united and harder of Digeſtion. Beſides, as I have before obſerved, they feed upon one another, and their Juices abound with a Salt that corrupts the Blood, and breeds chronical Diſeaſes. And 'tis always obſervable, that thoſe who live much on Fiſh are infected with the Scurvy, cutaneous Eruptions, and the other Diſeaſes of a foul Blood. And every Body finds himſelf more thirſty and heavy than uſual after a full Meal of Fiſh, let them be ever ſo freſh; and is generally forced to have Recourſe to Spirits and diſtilled Liquors to carry them off: So that it is become a Proverb, among thoſe that live much upon them, that Brandy is Latin for Fiſh. Beſides, that after a full Meal of Fiſh, even at Noon, one never ſleeps ſo ſound the enſuing Night; as is certain from conſtant Obſervation. Theſe few Hints may ſerve the valetudinary Perſon, in a groſs Manner, to judge by [42] the Eye the Quantity of ſolid Fleſh Meat he takes or ought to take down: For I judge the mentioned Quantities to be rather a little under than over eight Ounces. As to Broths, Soops, and Jellies, if they be ſtrong, I account them equal in Nouriſhment and harder to digeſt than the ſame Weight of ſolid Fleſh Meat; and three or four common Spoonfuls, atmoſt, make an Ounce in Weight in Liquids; and about double the Number of Bits commonly ſwallowed at once make the ſame Weight in ſolid Fleſh Meat; for Exactneſs is not here requiſite.

§. 12.

Drink is the other Part of our Food. The common Drink here in England is either Water, Malt-Liquor, or Wine, or Mixtures of theſe; for Cyder and Perry are drank but in few Places, and rather for Pleaſure and Variety than common Uſe. Without all peradventure, Water was the primitive, original Beverage, as it is the only Simple Fluid (for there are but three more in Nature, Mercury, Light, and Air, none of which is fit for human Drink) fitted for diluting, moiſtening and cooling; the Ends of Drink appointed by Nature. And happy had it been for the Race of Mankind other [43] mixt and artificial Liquors had never been invented. It has been an agreeable Appearance to me to obſerve, with what Freſhneſs and Vigour, thoſe who, tho' eating freely of Fleſh Meat, yet drank nothing but this Element, have lived in Health, Indolence, and Chearfulneſs, to a great Age. Water alone is ſufficient and effectual for all the Purpoſes of human Wants in Drink. Strong Liquors were never deſigned for common Uſe: They were formerly kept (here in England) as other Medicines are, in Apothecaries Shops, and preſcribed by Phyſicians, as they do Diaſcordium and Venice-Treacle; to refreſh the Weary, to ſtrengthen the Weak, to give Courage to the Faint-hearted, and raiſe the Lowſpirited. And it were as juſt and reaſonable to ſee Men (and if they go on, it is not impoſſible I may hear of it, ſince Laudanum is already taken into Feaſts and Entertainments) ſit down to a Diſh of Venice-Treacle, or Sir Walter Rawleigh's Confection, with a Bottle of Hyſterick Cordial, as to a Diſh of Crawfiſh-Soop, an Ox-Cheek or VeniſonPaſty, with a Bottle of Hermitage, or Tockay, or which ſome prefer to either of them, a Bowl of PUNCH. Wine [44] is now become as common as Water; and the better Sort ſcarce ever dilute their Food with any other Liquor. And we ſee, by daily Experience, that (as natural Cauſes will always produce their proper Effects) their Blood becomes inflammed into Gout, Stone, and Rheumamatiſm, raging Fevers, Pleuriſies, Small Pox, or Meaſles; their Paſſions are enraged into Quarrels, Murder, and Blaſphemy; their Juices are dried up; and their Solids ſcorch'd and ſhrivel'd. Thoſe whoſe Appetite and Digeſtion is good and entire, never want ſtrong Liquors to ſupply Spirits: Such Spirits are too volatile and fugitive for any ſolid or uſeful Purpoſes in Life. Two Ounces of Fleſh Meat, well digeſted, beget a greater Stock of more durable and uſeful Spirits, than ten Times as much ſtrong Liquors, which nothing but Luxury and Concupiſcence makes neceſſary. Happy thoſe, whom their Parents, their natural Averſion to ſtrong Liquors, or whom kind Providence among the better Sort, has brought to the Age of Maturity and Diſcretion, without dealing in or deſiring any great Quantity of ſtrong Liquors: Their Paſſions have been calmer, their Senſations [45] more exquiſite, their Appetites leſs unruly, and their Health more uninterrupted, than any other natural Cauſe could have produced. And thrice happy they, who continue this Courſe to their laſt Minutes. Nothing is more ridiculous than the common Plea for continuing in drinking on, large Quantities of ſpirituous Liquors; viz. Becauſe they have been accuſtomed ſo to do, and they think it dangerous to leave it off, all of a ſudden. It were as reaſonable for him that is fallen into the Fire or Water to lie there, becauſe of the Danger of removing him ſuddenly. For neither Element will deſtroy him more certainly, before his Time, than wallowing in ſtrong Liquors. If the Quantity of ſtrong Liquors they have been accuſtomed to, may be ſuppoſed prejudicial to their Health, or to introduce noxious Humours into the Habit; the ſooner a Stop be put to it, the better. No Man is afraid to forbear ſtrong Liquors in an acute Diſtemper, what Quantity ſoever he might have drank in his Health: And yet any ſudden Change of the Humours would not only be more dangerous then, than at any other Time; but alſo would more readily happen and come to paſs, in ſuch critical Caſes. For the whole Syſtem [46] of the Fluids, being in a Fermentation, ſmall Changes or Errors then, would not only be more fatal, but more plain and obvious. And if a Perſon be in Hazard by ſuch a ſudden Alteration, he cannot live long by taking down ſo much Poiſon. But the Matter of Fact is falſe and groundleſs. For I have known and obſerved conſtant good Effects from leaving off ſuddenly great Quantities of Wine and Fleſh Meats too, by thoſe long accuſtomed to both, am ready to name the Perſons, and never obſerved any ill Conſequence from it in any Caſe whatſoever. Thoſe whoſe Conſtitutions have been quite broken, and running into Diſſolution, have lived longer, and been leſs pained in Sickneſs by ſo doing: And thoſe who have had a Fund in Nature to laſt longer, have grown better, and attained their End by it. I allow every Man, that has been accuſtomed to drink Wine, or ſtrong Liquors, a Pint in 24 Hours: And I am well ſatisfied, that Quantity is ſufficient for Health, let their Cuſtom have been what it will. Their Spirits may indeed flag and ſink a little at firſt, for Want of introduced Quicklime and Fire. But Low-ſpiritedneſs, in ſuch a Caſe, I count no Diſeaſe. And [47] bearing it for ſome Time, is bountifully recompenced by the Health, Indolence, and Freedom of Spirits, they afterwards enjoy: Not taking into Conſideration their being reſcued from the Tyranny of ſo immoral and miſchievous a Habit. It may be ſufficient for thoſe who are tender, ſtudious, or contemplative, to drink three Glaſſes of Water with a Spoonful of Wine at the great Meal. And as Sir W. Temple has it, One for your ſelf, another for your Friends, a third for good Humour, and a fourth for your Enemies, are more than ſufficient after it.

§. 13.

A great Miſtake committed in this Affair is, that moſt People think the only Remedy for Gluttony is Drunkenneſs, or that the Cure of a Surfeit of Meat is a Surfeit of Wine: Than which nothing can be more falſe, or contrary to Nature; for, 'tis lighting, as the Saying is, the Candle at both Ends. For, firſt of all, Wine and all other ſtrong Liquors are as hard to digeſt, and require as much Labour of the concoctive Powers, as ſtrong Food itſelf. This is not only evident with Reſpect to People of weak Stomachs, but alſo from hence, that healthy [48] People who drink only Water, or weak ſmall Beer, ſhall be able to eat and digeſt almoſt double of what they could, did they drink ſtrong Liquors at their Meals, as every one that pleaſes may experience. Water is the only univerſal Diſſolvent or Menſtruum, and the moſt certain Diluter of all Bodies proper for Food; tho' there are a great many that ſpirituous Liquors not only will not diſſolve, but will harden, and make more undigeſtible; eſpecially the Salts of Bodies, wherein their active Qualities, that is, thoſe which can do moſt Harm to human Conſtitutions, conſiſt. And I have known Men of weak and tender Conſtitutions, who could neither eat nor digeſt upon drinking of Wine, who, by drinking at Meals common Water heated, have recovered their Appetites and Digeſtion, have thriven and grown plump. 'Tis true ſtrong Liquors, by their Heat and Stimulation on the Organs of Concoction, by encreaſing the Velocity of the Motion of the Fluids, and thereby quickening the other animal Functions, will carry off the Load that lies upon the Stomach, with more preſent Chearfulneſs: Yet, beſides the future Damages of ſuch a Quantity of Wine, to the Stomach [49] and to the Fluids, by its Heat and Inflammation, the Food is hurried into the Habit, unconcocted, and lays a Foundation for a Fever, a Fit of the Cholick, or ſome chronical Diſeaſe.

§. 14.

Another Miſtake I ſhall obſerve, is the extreme Fondneſs Perſons of the better Sort here in England, have lately run into, for the ſtrong and high Country Wines. I can think of no Reaſon for this, but the very honeſt one the Vulgar give for drinking Brandy: that they get ſooner drunk on it. For ſurely the middling lighter Wines, inflame the animal Juices leſs, go more eaſily off the Stomach, and afford more Room for long Converſation and Chearfulneſs. Exceſs in them, gives leſs Pain, and is ſooner remedied. But there are Degrees in this Matter. * Nemo repente fuit turpiſſimus. They begin with the weaker Wines; theſe by Uſe and Habit will not do, they leave the Stomach ſick and mawkiſh, they muſt fly to ſtronger Wine, and ſtronger ſtill, and run the Climax, through Brandy to Barbadoes Waters, and double diſtill'd Spirits, 'till at laſt they can find nothing [48] [...] [49] [...] [50] hot enough for them. People who have any Regard for their Health or Lives, ought to tremble at the firſt Cravings, for ſuch poyſonous Liquors. Strong Waters ſhould never be taken but by the Direction of a Phyſician, or in the Agonies of Death. For when Perſons arrive at that State, that they become neceſſary to their Eaſe and Freedom of Spirits; they may be juſtly reckoned among the Dead, both as to the ſhort Time they have to live, and the little Uſe they can be of either to themſelves or Mankind. I ſpeak not here of thoſe who are under an actual Fit of the Gout, or Cholick in the Stomach. (We muſt not die for fear of dying.) Nor am I recommending ſour Verjuice or unripe Wines. But I cannot help being well ſatisfied, both from Reaſon and Experience, that the light Wines, of a moderate Strength, due Age and full Maturity, are much preferable for Chearfulneſs and Converſation, much more wholſome for human Conſtitutions, and much more proper for Digeſtion than the hot and ſtrong Wines. The rich, ſtrong, and heavy Wines ought never to be taſted without a ſufficient Dilution of Water; at leaſt they ſhould be uſed, like Brandy or Spirits, for a Cordial*. [51] Ad ſummum tria pocula ſume. Whatſoever is more cometh of Sin, and muſt be diluted with the Waters of Repentance.

§. 15.

I have no Intention here to diſcourage the innocent Means of enlivening Converſation, promoting Friendſhip, comforting the ſorrowful Heart, and raiſing the drooping Spirits, by the cheerful Cup and the ſocial Repaſt. Perhaps I may like the harmleſs Frolick, the warm Reception of a Friend, and even the Dulce Furere itſelf, more than I ought: Perſons ſober in the main, will receive little Prejudice from ſuch a Fillip, when the Occaſions happen but ſeldom, and eſpecially when they make it up, by a greater Degree of Abſtinence afterwards. But a Sot is the loweſt Character in Life. Did only the Profligate, the Scoundrel, the Abandon'd, run into theſe Exceſſes, it were in vain to endeavour to reclaim them, as it were, to ſtop a Tempeſt, or calm a Storm. But now that the Vice is become Epidemical, ſince it has got not only among Mechanicks and Tradeſmen, but among Perſons of the brighteſt Genius, [52] the fineſt Taſte, and the moſt accompliſh'd Parts; and (oh that I could give my Conſcience the Lye, in mentioning them!) even among the firſt and leaſt fallen Part of the Creation itſelf, and thoſe of them too, of the moſt elegant Parts, and the ſtricteſt Virtue otherwiſe; and which is ſtill the moſt ſurpriſing of all, even thoſe too, who are in all other Reſpects blameleſs. Since I ſay the Caſe is ſo, it will not be amiſs to ſhew, to the Evidence of a Demonſtration, the Folly as well as the Fruitleſſneſs of ſuch a Courſe. A Fit of the Colick, or of the Vapours, a FamilyMisfortune, a caſual Diſappointment, the Death of a Child, or of a Friend, with the Aſſiſtance of the Nurſe, the Midwife, and the next Neighbour, often give Riſe and become the weighty Cauſes of ſo fatal an Effect. A little Lowneſs requires Drops, which paſs readily down under the Notion of Phyſick; Drops beget Drams, and Drams beget more Drams, 'till they come to be without Weight and without Meaſure; ſo that at laſt the miſerable Creature ſuffers a true. Martyrdom, between its natural Modeſty, the great Neceſſity of concealing its Cravings, and the ſtill greater one of getting them ſatisfied ſome how. Higher and more [53] ſevere Fits of Hyſtericks, Tremors, and Convulſions, begot by theſe, bring forth farther Neceſſity, upon Neceſſity, of Drops, Drams, and Gills, 'till at laſt a kind Dropſy, nervous Convulſions, a nervous Atrophy, or a colloquative Diarrhaea, if not a Fever, or a Frenzy, ſet the poor Soul free. It has very often raiſed in me the moſt melancholy Reflexions, to ſee even the Virtuous, and the Senſible, bound in ſuch Chains and Fetters, as nothing leſs than omnipotent Grace, or the unrelenting Grave could releaſe them: They were deaf to Reaſon and Medicine, to their own Experience, and even to the expreſs Words of Scripture, that ſays, the Drunkard ſhall not inherit the Kingdom of Heaven. Did this bewitching Poiſon actually cure or relieve them, from Time to Time; ſomething might be ſaid to extenuate the Folly and Frenzy of ſuch a Courſe. But, on the contrary, it heightens and enrages all their Symptoms and Sufferings, ever afterwards, excepting the few Moments immediately after taking it down; and every Dram begets the Neceſſity of two more, to cure the ill Effects of the firſt; and one Minutes Indolence they purchaſe with many Hours of greater Pain and Miſery; beſides the making the Malady, [54] more incurable. Low-ſpiritedneſs in itſelf is no Diſeaſe; beſides that there are Remedies in Art that will always relieve it, ſo long as there is any Oil remaining in the Lamp; and 'tis in vain to try to raiſe the Dead. Exerciſe, Abſtinence, and proper Evacuations, with Time and Patience, will continually make it tolerable, very often they will perſectly cure it. The running into Drams is giving up the whole at once; for neither Laudanum nor Arſenick will kill more certainly, although more quickly. The Pretence of its being Phyſick, or a preſent Remedy, is trifling. Cordials of any Kind, even out of the Apothecaries Shops, are but Reprieves for a Time, to gain a Reſpite, 'till proper and extirpating Remedies can take Place; and are never to be uſed twice, the one immediately after the other, but in the laſt Neceſſity. And I can honeſtly ſay, I never failed of relieving, ſo as to make Life tolerable, vapouriſh, hyſterical, or hypochondriacal Perſons, who would be governed in their Diet, by the Uſe of other proper Means, if their was a Fund in Life, and no incurable Diſeaſe, complicated with Lowneſs. Thus much the Weight of the Subject forced from one: [55] more than this, its Diſagreeableneſs hinders me to ſay.

§. 16.

Next to Drams, no Liquor deſerves more to be ſtigmatized and baniſhed the Repaſts of the Tender, Valetudinary, and Studious, than PUNCH. 'Tis a Compoſition of ſuch Parts, as not one of them is ſalutary, or kindly to ſuch Conſtitutions, except the pure Element in it. The principal Ingredient is Rum, Arrack, Brandy, or Malt Spirits, as they are called, all of them raiſed by the Fire, from the fermented Juices of Plants, brought from Southern Countries, or which have longeſt born the Heat of the Sun in our own Climate: And 'tis obſervable, that every Thing that has paſt the Fire, ſo that it has had due Time to divide and penetrate its Parts, as far as it poſſibly can, retains a cauſtick, corroſive, and burning Quality ever afterwards. This is evident from the fiery and burning Touch and Taſte of new-drawn Spirits, as alſo from the burning of Lime-ſtone, which, tho' extinguiſh'd by Boiling Water, does ever after retain its heating and drying Quality, as appears from the great Uſe of Lime-Water, in drying up all humid Sores, when given inwardly by itſelf, or compounded [56] with ſudorific Woods and Roots, and from its Succeſs in outward Applications for the ſame Purpoſes. And tho' Time may in ſome Meaſure get the better of this, in its ſenſible and obvious Operations; yet ſince Water is a groſſer Body than Fire, or Flame, it never can penetrate it ſo far as quite to extinguiſh its inmoſt Heat; eſpecially if we conſider, that Spirits are but an Accumulation of fine Salts and light Oil, compacted together into the ſmalleſt Volume; the firſt whereof is ſo hard and ſolid, as naturally to retain their Heat the longeſt, into which Water cannot enter; the other, to wit the Oyle, is ſo inflamable, that it moſt readily receives Heat and Fire, and defends the Salts from the Power of the Water over them. And in the continued Diſtillation of Spirits, this Action of the Fire is ſo ſtrong, as to reduce them to liquid Flames at laſt, which will of themſelves evaporate in viſible Flames and Fumes. The other principal Part of the Compoſition is the Juice of Oranges and Lemons. And if we conſider, that a Lemon or Orange could never be tranſported half Seas over to us, without rotting or ſpoiling, if gathered when wholly ripe, we ſhould have no great Opinion of their Juices. Every Spaniſh or Portugal Merchant can inform [57] us, that they muſt be gathered green, or at leaſt a Month before they are ripe, elſe they are not fit to be ſent beyond the Seas. The Sea-Air, and their being ſhut up cloſe, gives them that golden yellow Colour, we ſo much admire. The Juice of a Crab Apple, of unripe Grapes, or Gooſe-berries, or even good Juice of Sorrel, would come up at leaſt to their Virtue of extinguiſhing the Heat of Spirits, if not to their Flavour. And how kindly a Gueſt ſuch Juices would be to the fine Fibres of weak Stomachs and Bowels, I leave every one to judge. The Truth is, all fermenting Juices, ſuch as theſe eminently are, muſt be highly injurious to weak Conſtitutions; for meeting with the Crudities in the Bowels, they muſt raiſe a new Battle and Colluctation there, and ſo muſt blow up the whole Cavities of the human Body, with acrid Fumes and Vapours, the great and ſore Enemy of ſuch Bowels. And in the Weſt Indies, where from the Neceſſity of drinking much, becauſe of the Violence of the Heat, and from the Want of proper Liquors there, they are forced to drink much PUNCH, tho' Lemons and Oranges be in their full Perfection, they are univerſally afflicted with Nervous and Mortal dry-Belly-aches, Palſies, [58] Cramps, and Convulſions; which cut them off in a few Days, entirely owing to this poiſonous Mixture.

The Bath-Water, is the only Remedy in ſuch Caſes, whither they all haſten, if they can get thither alive. And here I have been inform'd of this Fact, by Men of the Profeſſion, as well as their Patients, who univerſally aſcrib'd them to their drinking of PUNCH and Spirituous Liquors. If Acids muſt be had, without all peradventure, the Vinous ones, are the beſt and ſafeſt. The Romans, tho' they had the vegetable Acids in perfection, made very little Uſe of them but in Cookery, where the Quantity of the Poiſon was ſo ſmall, as not to do ſufficient Harm, to forbid their uſing them for the Sake of the exquiſite Reliſh they gave their Sauces; and the conſtant Drink of the lower Souldiery, was Vinegar and Water, which they found of excellent Uſe, both as it prevented Fevers, Plagues and Putrefaction, and alſo as it gave an Energy to the unactive Element, and hindered it from lodging in the Body. Hence alſo the great Uſe of Oxymel and Oxycrate, (that is, of Vinegar with Honey and with Water) among all the antient Phyſicians. And indeed, whenever [59] they preſcrib'd an Acid, they very prudently join'd a Corrective with it, both to promote its good, and to prevent it's bad Effects. The two remaining Ingredients, are Sugar and Water; and theſe I will give up to the PunchDrinkers, and allow them all the Benefit of them, they can bring to this Compoſition: Yet it will ſtill have Malignity ſufficient remaining, to be held in Deteſtation, (at leaſt for any great Uſe, or in any great Quantity, for ſome Poiſons are ſo only by their Quantity) by thoſe tender and valetudinary Perſons, who value Health and Life. The Strong, the Voluptuous, and the Abandoned, need no Advice, at leaſt they will take none. I could never ſee any Temptation, for any one in their Senſes, to indulge in this Heatheniſh Liquor, but that it makes it's Votaries the ſooneſt, and all of a ſudden the deepeſt Drunk, holds them longeſt in the Fit, and deprives them the moſt entirely of the Uſe of their Intellectual Faculties, and Bodily Organs, of any Liquor whatſoever. It is likeſt Opium, both in it's Nature, and in the Manner of its Operation, and neareſt Arſenick in it's deleterious and poiſonous Qualities: And ſo I leave it to them,

[60] Who knowing this, will yet drink on and die.

§ 17.

As to Malt Liquors, they are not much in Uſe, excepting ſmall Beer, with any but Mechanicks and Fox-hunters. The French very juſtly call them Barley-Soop. I am well ſatisfied, a weak Stomach can as readily and with leſs pain, digeſt Pork, and Peaſe-Soop, as Yorkſhire or Nottingham Ale. They make excellent Birdlime, and when ſimmer'd ſome time over a gentle Fire, make the moſt ſticking, and the beſt Plaiſter, for old Strains that can be contriv'd. Even the ſmall-Beer that is commonly drank at London, if it be not well Boiled, very Clear, and of a due Age, muſt be hurtful to Perſons of weak Nerves, and ſlow Digeſtion. For fermenting again in the alimentary Channels, it will fill the whole Cavities of the Body with Windy Fumes and Vapours, which will at Length play odd Pranks in a craſy Conſtitution. In Fine, the Valetudinary, Studious, and Contemplative, muſt be contented with a Pint of middling, light Wine a Day, one half with, and the other without Water.

§ 18.

Since the Time foreign Luxury has been brought to it's Perfection here, [61] there are a kind of Liquors in Uſe among the better Sort, which ſome great Doctors have Condemn'd, by Bell, Book, and Candle, and others have as extravagantly commended: I mean, Coffee, Tea, and Chocolate. For my own Part, I take all their Virtue to conſiſt in Cuſtom, and all their Harm in Exceſs. As to Coffee, it is a meer Calx, or a Kind of burnt Horſe Bean, but lighter on the Stomach, and of ſomewhat a better Flavour. The Turks uſe it, and Opium inſtead of Brandy. But the Plea that ſome make for running into Exceſs in it, from this Mahometan Cuſtom, is altogether weak and groundleſs; for thoſe that do ſo there, ſuffer by it, as we do here: And thoſe that Debauch in it, turn Stupid, Feeble, and Paralitick by it, eſpecially when they join Opium with it, as they frequently do, as thoſe who wallow in theſe, do here, and are as much Deſpis'd and Expos'd by ſerious Perſons, as our Topers and Brandy-ſwillers are here. A Diſh or two of Coffee, with a little Milk to ſoften it, in raw or damp Weather, or on a Wateriſh and Flegmatick Stomach, is not only innocent, but a preſent Relief. But 'tis as ridiculous, and perhaps more hurtful, at leaſt in thin and dry Habits, to dabble in it two or [62] three Times every Day, as it would be for ſuch to drink nothing but ſcalding Lime-Water. There are two Kinds of Tea in Uſe, Green and Bohea. Mr. Cuningham, who liv'd ſeveral Years in China, a very learned and accurate Perſon *informs us, that they are both gathered from the ſame Shrub, but at different Seaſons of the Year; and that the Bohea is Gather'd in the Spring, and is dried in the Sun, the Green at the Fire. But I ſuſpect, and not without Authority, that, beſides theſe Differences in drying, ſome Infuſion of another Plant or Earth (perhaps ſuch a one as that of Japan Earth, or Catechu) muſt be poured on ſome ſorts of Bohea Tea, to give it the Softneſs, Flavour, and Heavineſs on the Stomach it has, whereby it becomes a meer Drug, and wants the natural Simplicity of Green Tea, which when light, and drank neither too Strong nor too Hot, I take to be a very proper Diluent, when ſoften'd with a little Milk, to cleanſe the alimentary Paſſages, and waſh off the Scorbutick and Urinous Salts, for a Breakfaſt, to thoſe who live full and free; as alſo it, or Tea made of a ſlic'd Orange or Lemon, is one of the beſt promoters of Digeſtion [63] after a full Meal, or when one is adry between Meals, and much more ſafe and effectual than Drams or ſtrong Cordials, which are commonly uſed for that Purpoſe. Some Perſons of weak tender Nerves, fall into Lowneſs and Trembling upon uſing either of theſe Liquors with any Freedom, from their too great Quantity, or their Irritation on the tender, and delicate Fibres of the Stomach. Such ought carefully to avoid and abſtain from them, as from Drams and Drops. But I can never be of their Opinion who aſcribe the Frequency of Scurvy, Vapours, Lowſpiritedneſs, and nervous Diſtempers now, to what they were in the Days of our Forefathers, to the Cuſtom of Drinking more frequently and freely of theſe foreign Infuſions. The Cauſe is not adequate to the Effect; nor indeed has any Analogy to, or Connexion with it. We know that warm Water, will moſt of any Thing promote and aſſiſt Digeſtion in weak Stomachs and tender Nerves. And by this alone I have ſeen ſeveral ſuch Perſons recover to a Miracle, when cold Mineral Waters, Bitters, Cordials and Drams, have done rather Hurt than Good. And Tea is but an Infuſion in Water of an innocent Plant: Innocent, I ſay, becauſe we find [64] by its Taſte it has neither poiſonous, deleterious nor acrimonious Qualities; and we are certain from it's Uſe in the Countries it comes from, (which are larger than moſt of Europe) that they receive no Damage from it, but on the contrary, that it promotes both Digeſtion and Perſpiration. The Argument from its relaxing the Coats of the Stomach and Bowels by its Heat, is of no force. For unleſs it be drunk much hotter than the Blood itſelf, it can do no hurt that way: And we ſee the Bath Guides, who dabble in Water almoſt as hot as Tea is ever drunk, a great Part of the Day, and for one half of the Year at leaſt, are no ways injured by it; except when they drink ſtrong Liquors, too freely to quench the Thirſt it raiſes. However, I ſhould adviſe thoſe who drink Tea plentifully, not to drink it much hotter than bloodwarm; whereby they will receive all its Benefit, and be ſecure againſt all the Harm it can poſſibly do. As to Chocolate, I am of opinion, it is too hot and heavy, for valetudinary Perſons; and thoſe of weak Nerves. I have before obſerved, that Nuts paſs through the alimentary Paſſages untouched; and tho' they may part with ſome of their more volatile Particles, yet, I doubt if they can afford [65] much nouriſhment to Perſons of weak Digeſtions. Some ſay, Chocolate gives them an Appetite; the meaning of which may be, that when they have a good Appetite for their Breakfaſt; it is not unlikely it may continue all the Day: But I am of opinion, 'tis a falſe and hyſterical Appetite, ſuch as ſharp Wines, and ſharp Humours in the Stomach give. For fat and oily Things, ſuch as all Nuts are, are hard to digeſt, and lie long in the Stomach, for reaſons I have already explain'd: It may lubricate and ſheath againſt the Irritation of ſalt and ſharp Humours in the Bowels, and therefore may be good in the Colicks and Gravel of thoſe of ſtrong and ſtout Digeſtion; but can never be good Food for thoſe of weak Nerves and poor Conſtitutions. Nothing is ſo light and eaſy to the Stomach, moſt certainly, as the Farinaceous or mealy Vegetables; ſuch as Peaſe, Beans, Millet, Oats, Barly, Rye, Wheat, Sago, Rice, Potatoes, and the like; of ſome of which on Milk or Water, I ſhould ever adviſe the Valetudinary, and thoſe of weak Nerves, to make their two leſſer or ſecondary Meals. Tobacco is another foreign Weed, much in uſe here in Britain; though not among the beſt, yet among the middle and inferiour Ranks of the People: For thoſe of groſs and [66] Phlegmatick Conſtitutions, who abound in ſerous and watry Humours, who are ſubject to Coughs, Catarrhs, and aſthmatick Indiſpoſitions; who labour under violent Tooth-achs, or are troubled with Rheums in their Eyes; who have cold and wateriſh Stomachs, and live fully and freely, both Smoaking and Chewing is a very beneficial Evacuation, drawing off ſuperfluous Humours, Crudities, and cold Phlegm, provided they carefully avoid ſwallowing the Smoak, or the Juice; and drink nothing, but rinſe their Mouths with ſome watry Liquor after it, and ſpit it out. But to thin, meagre, and hectick Conſtitutions, it is highly pernicious, and deſtructive; heating their Blood, drying their Solids, and defrauding the Food of that Saliva, which is ſo abſolutely neceſſary towards Concoction. Snuffing the Leaves, or the groſſer Cut in a Morning, will readily promote a Flux of Rheum by the Glands of the Noſe; and will be of good uſe, to clear the Head and the Eyes. But the ridiculous Cuſtom, of perpetually ſucking in ſophiſticated Powders, and other Foreign Drugs ſold for Snuff, cannot but be prejudicial both to the Eyes, and even to the Stomach; at leaſt, if we believe the Reports of thoſe who ſay they have brought it up from thence.

§. 19.

[67]

I have endeavour'd to aſſiſt the Reader, with ſome Obſervations and Reflexions, to enable him towards determining the Quantity and Quality of his ſolid Food, neceſſary either to prevent or cure chronical Diſtempers. It may not be amiſs, here to make ſome Reflexions alſo on the fit Proportion of Drink proper for that purpoſe: As the Food is, ſo muſt that be, various and uncertain, with regard to the Age, Size, Labour, and Conſtitution of the Perſon, and the Seaſon of the Year. I have offer'd to limit the Quantity of ſtrong Liquors, fitteſt to preſerve Health and lengthen out Life in general, to a Pound or Pint, and that of the middling Kind. But the Sickly, the Aged, and thoſe who would cure a chronical Diſtemper, muſt even abate of this Quantity. The only remaining Queſtion, is about the Quantity of Water, or watry Liquors, proper to be mix'd with this ſtrong Liquor, or drunk by itſelf: For in this alſo, though in itſelf harmleſs and innocent, yet there is a Choice and Preference; becauſe, too much Water will only ſerve to diſtend and ſwell up the Veſſels, and waſh off ſome of the finer and more nutritious parts of the Chyle; and too little, will not be ſufficient to dilute the ſolid Food, or to make the Chyle thin [68] and fluid enough, to circulate through the fine and ſmall Veſſels. I will ſuppoſe my Patient to deal in no other Cookery, but Roaſting and Boiling; and that he eats only freſh Meat. Boiling animal Food, draws more of the rank, ſtrong, Juices from it, and leaves it leſs nutritive, more diluted, lighter and eaſier of Digeſtion. Roaſting on the other hand, leaves it fuller of the ſtrong nutritive Juices, harder to digeſt, and wanting more Dilution: Thoſe therefore, who muſt have full grown and adult animal Food, ought to eat it boiled, and well boiled too; if their Digeſtion be but weak. They who can live on young animal Food, (which is beſt for weak Stomachs,) ought to eat it roaſted, but muſt leſſen the Quantity, in reſpect of the ſame Food boiled; but they muſt dilute it more: For as roaſt Meat has a better Flavour, and more Nouriſhment, ſo it lies leſs flabby on the Stomach, and does not ſo readily ſlip from, or diſappoint the Action of Grinding, which has ſome ſhare in Digeſtions, both primary and ſubſequent: But it will want more Dilution, with a watry Menſtruum, to ſoften its more rigid and criſp Fibres. If therefore, the whole Weight of the ſolid Food, in twenty four Hours, be ſuppoſed a Pound and a Half, [69] then three Pounds of Liquor, that is, one of ſtrong Liquor, and two of ſome aqueous Fluid, will in a Medium, be ſufficient to dilute it abundantly. For thus there will be two Particles of a Fluid, to one ſolid Particle; which abating the ſolid Parts thrown off by Siege, will ſuffice to make the Chyle abundantly thin, to circulate through all the fine Channels, whoſe Diameters are larger than that of the ſolid Particle, the principal End of its Thinneſs and Fluidity. More than this, would but diſtend the Veſſels, and carry off the finer Parts of the Chyle by Water or Perſpiration; for we conſtantly find both theſe encreaſed by an overdoſe of Fluids: And leſs would not ſufficiently dilute their Food. I ſhould adviſe thoſe therefore, who have weak Stomachs, or relaxed Nerves, to mix their Wine with the above-named quantity of boiled Water, with a burnt Cruſt, at leaſt Blood-warm, and to drink it after their Meal is over, if they can do it with eaſe, rather than in the Time of Eating: For the more ſpirituous and moſt nouriſhing Parts of the Food, will readily run off, without much Dilution; and it will be the groſſer and harder remaining Part, that will want it moſt. And if ſome time after their great Meal, they find their Stomach loaded, the Food riſing, hard Belching, [70] Heart-burning, or much Yawning, to ſwill down and dilute it with milk-warm, light Green Tea, or warm Water, rather than to run to Drams and Cordials, the uſual, but moſt pernicious Antidote in ſuch Caſes. And upon great and heavy Oppreſſion, much trouble and great ſtruggle in the Digeſtion, to have recourſe to Carduus or Camomile-Flower Tea, to bring it up, rather than to treſpaſs in theſe poiſonous and cauſtick Liquors; which, though they may at preſent leſſen the ſuffering, and hurry on the firſtConcoction; yet make them dearly pay for it, when the unconcocted load of Crudities comes to paſs by Siege or Perſpiration, either in Colicks, Gripes, Vapours, and Oppreſſion of Spirits; or by a general Diſability and Rheumatick Stitches and Pains.

§. 20.

Upon the Head of Cordials mentioned in one of the foregoing Articles, I cannot forbear ſetting down one, whoſe Virtues and Efficacy I have long tried, and have never found it fail, when any thing would ſucceed: And I recommend it (to be kept by them) to all thoſe, who are liable to low Spirits, Faintings, Oppreſſions, Sickneſs at the Stomach, Head-achs, and Vapours; and alſo to thoſe who wanting to exert themſelves [71] in any buſineſs of conſequence, need a Flow of Spirits for ſome ſhort time, for that purpoſe; or indeed upon any ſudden accident ariſing of its own accord, out of the Habit itſelf; I think it a kind of an univerſal Remedy, but never to be uſed, but upon ſuch occaſions; becauſe, Uſe may weaken it, if not extinguiſh its Vertue. 'Tis thus,

Take of ſimple Chamomile-Flower Water, ſix Ounces; Compound Gentian, and Wormwood Waters, each an Ounce and a Half; Compound Spirit of Lavender, ſal Volatile, Tincture of Caſtor, and Gum Ammoniack diſſolved in ſome ſimple Water, each two Drams; Tincture of Snakeweed, and Tincture of the Species Diambrae, each a Dram; the Chymical Oils of Lavender, Juniper, and Nutmeg, each ten Drops, mixed with a Bit of the Yolk of an Egg, to make the whole uniform; Aſſafetida and Camphire in a Rag, each half a Dram: But theſe may be left out by thoſe to whom they are diſagreeable.

Two, three or four Spoonfuls of this is a preſent Help in ſuch Caſes. It will keep ſix Months good.

General Rules for Health and Long Life, drawn from the Head of MEAT and DRINK.

[72]
  • 1. THE great Rule of Eating and Drinking for Health, is to adjuſt the Quality and Quantity of our Food to our digeſtive Powers. The Quality may be judged by the following Rules.
  • 2. Thoſe Subſtances that conſiſt of the groſſeſt Parts are hardeſt of Digeſtion; the conſtituent Particles coming into more Contacts, and conſequently adhering more firmly.
  • 3. Theſe Subſtances whoſe Parts are brought together with the greateſt Force, cohere proportionably cloſer, than thoſe that come together with a ſmaller * Momentum.
  • 4. Salts are very hard to be ſeparated, becauſe united by plain Surfaces, under which they are always comprehended. And in the laſt Stages of the Circulation, where it is ſlower, ſhoot readily into larger Cluſters, and ſo are harder to be driven out of the Habit. From theſe we may eaſily infer, that (1.) Thoſe Vegetables and Animals that come ſooneſt to their full Growth are eaſier of Digeſtion, than thoſe that are longer of attaining [73] the State of Maturity. (2.) Thoſe that are the ſmalleſt of their Kind, than the biggeſt. (3.) Thoſe of a dry, fleſhy and fibrous Subſtance, than the oily, fat, and glutinous. (4.) Thoſe of a white Subſtance, than thoſe of a more flaming Colour. (5.) Thoſe of a mild, ſoft, and ſweet, than thoſe of a ſtrong, poignant, aromatical, or hot Taſte. (6.) Land-Animals, than Sea-Animals. (7.) Thoſe Animals that live on Vegetables, or other light Food, than thoſe that live on other Animals, or hard and heavy Food. (8.) The Nouriſhment Nature has appointed for young Animals, is lighter than the Fleſh of theſe Animals themſelves.
  • 5. All cramm'd Poultry and ſtall-fed Cattle, and even Vegetables forced by hot Beds, tend more to Putrefaction, and conſequently are more unfit for human Food, than thoſe brought up in the natural Manner.
  • 6. Plain-dreſſed Food is eaſier of Digeſtion, than what is pickled, ſalted, baked, ſmoaked, or any Way high-ſeaſoned.
  • 7. Strong Men, thoſe of large Stature, and much Labour, and the Inhabitants of a cold and clear Air, require more Food than Women, Children, the Weak, the Sedentary, and the Aged, and thoſe that live in a warmer Climate, or groſſer Air.
  • [74]8. Nothing conduces more to Health and Long Life, than Abſtinence and plain Food, with due Labour.
  • 9. Where Exerciſe is wanting (as in ſtudious Perſons) there is the greater Need of Abſtinence; for theſe, 8 Ounces of animal, and 12 of vegetable Food, in 24 Hours, is ſufficient.
  • 10. Moſt chronical Diſeaſes proceed from Repletion; as appears from their being cured by Evacuation.
  • 11. Tender Perſons ought to uſe as much Abſtinence, as they poſſibly can: And, if they neglect it, their only Relief is from frequent ſtomachick and Family-Purges.
  • 12. A plain Rule for judging of the Quantity is, not to eat ſo much as indiſpoſes for Buſineſs.
  • 13. A more ſenſible and readier one is, firſt by Experience to find out how much fits one, ſo as to be lightſome and healthy under it, and ever after to judge the Quantity by the Eye; Nature requiring therein no mathematical Exactneſs.
  • 14. Pork and Fiſh are not fit Food for the Studious and the Tender.
  • 15. Water is the moſt natural and wholeſome of all Drinks, quickens the Appetite, and ſtrengthens the Digeſtion moſt.
  • [75]16. Strong and ſpirituous Liquors freely indulged, become a certain tho' a ſlow Poiſon.
  • 17. There is no Danger in leaving them off all at once; the Plea for continuing them being falſe and groundleſs.
  • 18. The beſt ſtrong Liquor for weak and ſtudious People is Wine; the beſt Quantity, a Pint in 24 Hours; and the beſt Way of drinking it is, three Glaſſes with, and three without Water.
  • 19. The middling, light Wines, fully ripe, and of a due Age, are preferable to the ſtrong Wines.
  • 20. Strong Liquors do not prevent the Miſchiefs of a Surfeit, nor carry it off, ſo ſafely as Water, tho' they ſeem to give preſent Relief.
  • 21. The frequent Uſe of Spirits in Drams and Cordials, is ſo far from curing Low-ſpiritedneſs, that it increaſes it, and brings on more fatal Diſorders.
  • 22. And even when they are diluted with Water, in PUNCH, the Quantity taken down at once, and the Addition of a corroding Acid, produce equally pernicious Effects in human Conſtitutions.
  • 23. Malt Liquors (excepting clear ſmall Beer, of a due Age) are extremely hurtful to tender and ſtudious Perſons.
  • [76]24. Coffee is only an Infuſion of a kind of Calx, and has the Effects of an abſorbent Medicine; and ſo may be of ſome Service to watry Stomachs, if moderately uſed.
  • 25. Green Tea is a good Diluter of the Food, as it is an agreeable, warm, ſmall Liquor: But Bohea is too heavy for the Stomach.
  • 26. Chocolate (as all Nuts elſe) is ſo heavy and hard of Digeſtion, that it can never be fit for the Stomachs of weak and tender People.
  • 27. Smoaking Tobacco, without drinking after it, Chewing or Snuffing the groſs cut Leaf in a Morning, are uſeful to flegmatick Conſtitutions; but to dry and lean Habits they are pernicious. Snuff is juſt good for nothing at all.
  • 28. The proper Quantity of watry Liquors in 24 Hours, to thoſe that live regularly, is two Pints, (as that of ſtrong Liquor is one Pint) which is beſt drank warm, and rather after than in the Time of Eating.
  • 29. The Form of a Cordial fit to be kept in private Families, as a preſent and certian Relief, for ſudden Qualms, Faintneſs, Sickneſs, or low Spirits; but never to be taken but in Caſe of Neceſſity.

CHAP. III. Of SLEEPING and WATCHING.

[77]

§. 1.

THE next general Head in order, is our Sleeping and Watching. All Bodies by their Actions upon one another, and by the Action of the circumambient Bodies, are liable to be impaired and waſted: And all animal Bodies, from an active and ſelf-moving Principle within them, as well as from the Rubs of Bodies without them, are conſtantly throwing off ſome of their ſuperfluous and decayed Parts; ſo that animal Bodies, are in a perpetual Flux. To reſtore this Decay and Waſting of animal Bodies, Nature has wiſely made alternate Periods of Labour and Reſt, Sleeping and Watching, neceſſary to our Being; the one for the active Employments of Life, to provide for and take in the Materials of our Nouriſhment; the other, to apply thoſe Materials to the proper waſted Parts, and to ſupply [78] the Expences of Living. And it ſeems as improper in the Order of Nature, to diſturb the animal Functions in the time of Sleep, by any other Employment, than that of the ſecondary Concoctions (as they are called;) i. e. the applying the Nouriſhment to the decayed Parts, to recruit the Blood, perfect the Secretions, and to lay up plenty of Spirits, or (to ſpeak more Philoſophically,) to reſtore the weakned Tone of nervous Fibres; that is in ſhort, to reſtore the Decays of Watching and Action: This I ſay, is as improper, as it would be (were it poſſible,) to eat or drink, or make proviſion for the Neceſſities of Life, in the time of Sleeping. From hence is evident, the Abſurdity of heavy, various and luxurious Suppers, or of going to Reſt till many Hours after ſuch a Meal; which muſt otherwiſe break in upon the Order of Nature and the due and appointed Times of Sleeping and Watching. Wherefore, I adviſe the Valetudinary, the Studious, and the Contemplative, either to make no Suppers, or only of vegetable Food; and to take a due Time for Watching after them.

§. 2.

There is nothing more certain, than that (abſtracting from acute Caſes) [79] our Sleep is ſound, ſweet and refreſhing, according as the alimentary Organs, are eaſy, quiet and clean. If any one not ſuffering under any diſeaſe, is diſturbed in his Sleep, 'tis certain his Stomach is filled with Food, or Crudities; or his Guts filled with Wind, Choler, or ſuperfluous Chyle: And thoſe reſtleſs Nights, and the difficulty of going to Sleep, which are generally aſcribed to Vapours, are entirely owing to theſe Cauſes; though they be not ſo ſtrong, as to become ſenſible; for then Pain is added to Watching and they are felt. And upon complaints of ſuch reſtleſs Nights, I never once failed, upon enquiry of finding the true Cauſe in the Diet, of the preceding Day, or of ſome few Days before; and conſtantly have diſcovered that ſome error in Eating and Drinking, either in Quantity or Quality has produced them. I have been aſtoniſhed to ſee hypochondriacal and hyſterical People, reſtleſs all Night, toſſing and tumbling till towards Morning, then dropping aſleep till late Hours, awake heavy, oppreſſed, and unrefreſhed, complain of being hag-ridden, tired and wearied, as if they had been whip'd, ſpurr'd, laſhed, and beaten thro' all the Watches of the Night; riſe with foul Mouths, and white Tongue, Belchings, [80] Yawnings, Coughing, Spitting, or Reaching and Heaving, without Appetite, Spirits or Life, all the Day-time; begin to live and breath, become cheerful and hungry, about ten, eleven, or twelve a clock at Night; eat a hearty, various, and luxurious Supper; drink a cheeruping Cup of the beſt, become as merry as Crickets, and long to ſit up later; at laſt, tumble to Bed, and repeat the ſame Farce over again. The Reaſon of all this Complaint, is the Load on the Stomach, that will not ſuffer them to reſt, till 'tis got off. The ſharp and crude Humours, twitching and twinging the nervous Fibres, and Coats of the Bowels, become like ſo many Needles and Pins, conſtantly running through them; though not always with ſenſible pain: The unconcocted Chyle ſtopping or circulating ſlowly, firſt in the Bowels, then in the ſmalleſt Veſſels, begets theſe Convulſions, Flatus, Night-Mares, and Oppreſſions of Spirits. So that the ſecondary Digeſtions are not over till next Evening, (hence their want of Appetite:) And when theſe are finiſhed their Stomachs come, and their Spirits flow; and thus the perpetual Round is carried on. Did they but follow the Dictates of Nature, go to Bed for ſome days with a light Vegetable, [81] or no Supper at all, and bear the Inconveniences thence ariſing; their Appetites would come in due ſeaſon, and they would quickly find the Truth of the Aphoriſm of the Schola Salernitana.

*Somnus ut ſit levis, ſit tibi Canoe brevis.’

§. 3.

The Seaſons for Sleeping and Watching, which Nature ſeems to point out to us, at leaſt in theſe our Climates near the Tropick, are the Viciſſitudes of Day and Night. Thoſe Damps, Vapours, and Exhalations, that are drawn up into the higher Regions, and are ſo rarified by the Heat and Action of the Sun, as to become innocent or very weak in the Day-time; are condenſed, ſink low, near the Surface of the Earth, and are perpetually dropping down in the Night Seaſon; and conſequently muſt be injurious to thoſe tender Perſons, that unnaturally watch in that Seaſon; and muſt neceſſarily obſtruct the Perſpiration, which the Activity of Watching, and the Motion of Labour promotes. I have already ſhewn, that our Bodies ſuck and [82] draw into them, the good or bad qualities of the circumambient Air, through the Mouths of all the perſpiratory Ducts of the Skin. And if we were to view an animal Body with a proper Glaſs, it would appear with an Atmoſphere quite round it, like the Steam of a boiling Pot. Now we may eaſily conceive, what injury a Conſtitution may receive, not only by ſtopping ſuch a perpetual Diſcharge of Superfluities, but alſo by forceing into the Habit, by the Air's Weight and Preſſure, thoſe noxious Fumes and Vapours, that are perpetually falling near the Surface of the Earth, in the Nighttime. Your true Topers are ſo ſenſible of this, that by Obſervation they have gathered it to be more ſafe for their Health, and better for prolonging their Lives, to get drunk betimes and go to Bed, than to ſit up and be ſober.

§. 4.

On the contrary, the Heat of the Sun in the Day-time, by its Action on human Bodies, the very Light, and free Air, and the Motions of things about us, diſturbing the Quiet of the Air, muſt neceſſarily diſorder the equable Courſe of the Perſpiration, the Tenour of the ſecondary Concoctions, and the Tranquillity of the Spirits ſo neceſſary to Reſt and [83] Quiet. So that nothing ſeems more directly pointed out to us by Nature, than the Day for Labour, and the Night for Reſt: And this without taking in the Conſideration of the Neceſſity of the Sun's Light for the ends of Labour, and providing the Neceſſaries of Life. Some Animals that are exceeding tender, are directed by Nature to alternate Periods of Watching and Reſt, not twice in 24 Hours, but twice in the Year, viz. Summer and Winter; ſuch as Swallows, Bats, and many ſorts of Inſects, who ſleep all the Winter, and watch all the Summer. So conſiſtent is Nature, in appointing the brighteſt and moſt enlightened Parts of our Lives for Action, and the darkeſt and moſt inclement for Reſt. Not but that robuſt Conſtitutions (as well as Animals fitted by Nature for different ways of living) may by Cuſtom, get the better of theſe natural Appointments: But I write for the Valetudinary, the Studious, and the Contemplative.

§. 5.

I adviſe all ſuch, if they would preſerve their Health and lengthen out their Days, to avoid as much as is poſſible evening Dews, nocturnal Studies, and unſeaſonable Watching; in Summer to go to Bed with the Sun, and in Winter to [84] riſe at leaſt by Break of Day. Thoſe who live temperately, will neceſſarily Sleep but little: But to recompence that, their Sleep will be much more ſound, refreſhing, and fruitful of Cheerfulneſs and free Spirits, than that of thoſe who live more freely. For as I have before ſaid, the Quantity of Sleep will always be in proportion to the Quantity of Eating and Drinking. Valetudinary, Studious, and Contemplative People, ought to go to Bed by eight, nine, or ten at fartheſt, and riſe by four, five, or ſix, by which they will have eight Hours a Bed; and that is ſufficient for any Perſon, not under an acute, or the ſharp Fits of à Chronical Diſtemper.

§. 6.

Nothing can be more prejudicial to tender Conſtitutions, ſtudious and contemplative Perſons, than lying long a Bed, or lolling and ſoaking in Sheets, any time after one is diſtinctly awake, or has ſlept a due and reaſonable Time: It neceſſarily thickens the Juices, enervates the Solids, and weakens the Conſtitution. A free open Air is a kind of a cold Bath, eſpecially after riſing out of a warm Bed; and conſequently makes the Circulation brisker and more compleat, and braces up the Solids, which lying a Bed diſſolves and [85] ſoaks in Moiſture. The erect Poſture, and the Activity of Watching, make the Perſpiration more plentiful, and the groſs Evacuations more readily thrown off. This is evident from the Appetite and Hunger, thoſe that riſe early feel, beyond that which they get by lying long a Bed. Add to all theſe the Influence of the freſh, benign, Morning Air, the retreating of all the noxious Damps and Vapours of the Night, together with the Clouds and Heavineſs, that are thrown upon the Brain from Sleep; and laſtly, that Cheerfulneſs and Alacrity that is felt by the Approach or Preſence, of that glorious Luminary the Sun, which adds a new Force to the Heart, and a Spur to the Spirits.

§. 7.

All Nations and Ages have agreed that the morning Seaſon is the proper Time for ſpeculative Studies, and thoſe Employments that moſt require the Faculties of the Mind. For then the Stock of the Spirits is undiminiſhed, and in its greateſt Plenty, the Head is clear and ſerene, the Paſſions are quieted and forgot; the Anxiety and Inquietude that the Digeſtions beget in the nervous Syſtem, in moſt tender Conſtitutions and the Hurry the Spirits are under after the great [86] Meal, are ſettled and wrought off. I ſhould adviſe therefore thoſe who are of a weak relaxed State of Nerves, who are ſubject to hypochondraical or hyſterical Diſorders, whoſe Profeſſions lead them to much Uſe of their intellectual Faculties, or who would indulge ſpeculative Studies, to go early to Bed, and to riſe betimes; to employ their morning Hours in theſe Exerciſes till eleven a Clock, then to take ſome agreeable Breakfaſt of vegetable Food; to go on with their Studies and Profeſſions till three, four, or five, as their Spirits will hold out, and then to take their great Meal of animal Food; all the reſt of the Day to throw off all Study and Thought, divert themſelves agreeably in ſome innocent Amuſement, with ſome gentle bodily Exerciſe; and as ſoon as the Digeſtion is over, to retire and provide for going to Bed, without any farther ſupplies, except it be a Glaſs of fair Water, or warm Sack-Whey. But the Aged and Sickly muſt go ſooner to Bed and lye longer, becauſe Age and Sickneſs break reſt, and the ſtiffen'd and hardened Limbs of the Antient become more pliant and relaxed by much Sleep, a ſupine Poſture, and the Warmth of the Bed.

Rules for Health and Long Life, drawn from the Head of SLEEP and WATCHING.

[87]
  • 1. THE Valetudinary, the Sedentary, and the Studious ſhould eat very light, or no Supper; if any, it ought to be vegetable Food; neither ought they to go ſoon to Bed, after any Supper whatſoever.
  • 2. Going to Bed on a full Stomach, and Wind and Crudities ſomewhere in the in the alimentary Paſſages, is the Cauſe of the want of due Reſt, which is ſound and refreſhing, always in Proportion to the Emptineſs and Cleanneſs of theſe Paſſages, and their Vacation from their proper Office of Digeſtion: And this is the Cauſe of the Want of kindly and refreſhing Reſt, in hypochondriacal and hyſterical People.
  • 3. Watching by Night and Sleeping by Day, is of the moſt pernicious Conſequence to Health and Long Life; and plainly contrary to the Indications of Nature and the Conſtitutions of our Bodies.
  • 4. The Valetudinary, Sedentary, and Studious, ought carefully to avoid evening Dews, nocturnal Studies, and unſeaſonable Watching; go to Bed by eight, [88] nine, or ten, and riſe proportionably by four, five, or ſix; unleſs actually under a Fit of Sickneſs.
  • 5. Nothing is more prejudicial to tender Conſtitutions, than lying long a Bed, indulging a lethargical and drowſy Sleep, or lolling or loitering awake; as appears by their Heavineſs, and want of Appetite, upon doing ſo; and their good Stomachs, Cheerfullneſs, and Freedom of Spirits, when they riſe early.
  • 6. The moſt advantagious manner for the Tender, Sedentary, and Studious, to beſtow their Time, on account both of their Health and Studies, is to go early to Bed, riſe betimes, go about their Studies till eleven, taking a light vegetable Breakfaſt; proſecute them till about four in the Afternoon, then to take their great Meal of animal Food, and after that to employ the reſt of their Time in ſome innocent Amuſement, or gentle bodily Exerciſe; to retire betimes, to prepare for going to Bed, taking no farther Nouriſhment, except a Draught of Water or warm SackWhey, which will be particularly uſeful to thoſe who labour under Stone and Gravel.

CHAP. IV. Of EXERCISE and QUIET.

[89]

§. 1.

WE proceed; in the next Place, to the Conſideration of Exerciſe and Quiet, the due Regulation of which, is almoſt as neceſſary to Health and Long Life, as Food itſelf. Whether we were ſo made before the Fall, as to live in intire Health, in a rigidly ſedentary and contemplative Life, is a Speculation of no great Conſequence, nor eaſily determined in our preſent Situation; for there is no certain Analogy between Things as they now are, and as they might have been then. As there happen'd an intire Revolution in the Complexion and Qualities of the Minds of the Firſt Pair; ſo, to me, there appear, to be evident Indications of a deſigned Change and Alteration of the material World, and the Nature of the Animals and Vegetables which ſubſiſt on this Globe, from what they were when GOD pronounced [90] every Thing Good that he had made. Nor ſeem the Coeleſtial Bodies to have eſcaped, ſo far as they regard us. Whatever be in this, the Paſſage where God tells Adam, * That in the Sweat of his Brow he ſhall eat Bread, ſeems to be the Injunction of a ſalutary Penance; that is, Not merely a Puniſhment, but alſo a Remedy againſt the Diſorders his Body would be liable to in this new State of the Creation, and againſt the poiſonous Effects of the Forbidden Tree he had eaten the Fruit of. I am the more confirmed in this Belief, that I obſerve, the abſolute Neceſſity of Labour and Exerciſe, to preſerve the Body any Time in due plight, to maintain Health, and lengthen out Life. For let whatſoever Diet be purſued, however adjuſted both in Quantity and Quality, let whatever Evacuations be uſed to leſſen the Malady, or any Succedaneum be propoſed, to prevent the ill Effects, our Bodies are ſo made, and the Animal Oeconomy now ſo contrived, that without due Labour and Exerciſe, the Juices will thicken, the [91] Joints will ſtiffen, the Nerves will relax, and on theſe Diſorders, Chronical Diſtempers, and a crazy old Age muſt enſue. Nor is this neceſſary only in the colder Climates, and where the Food is groſs, but even in the warmeſt Climates, and where the Food is lighteſt. For though the Warmth of the Air may keep the Perſpiration free and open, or rather, where it is very great, promote Sweating; yet, at the ſame time, and by Conſequence, it will thicken the Fluids, and relax the Fibres; to prevent both which, Exerciſe is abſolutely neceſſary: but in ſuch a Climate it ought to be gone about in the Cool of the Day. And tho' light Food may, in a great meaſure, prevent the Thickening of the Fluids, yet it cannot do it ſufficiently without Exerciſe; nor can it at all keep the Fibres in due Tenſion; for to that purpoſe Exerciſe is abſolutely neceſſary. Nay, the joint Power of warm Air and light Food cannot ſupply the Place of Exerciſe in keeping the Joints pliant and moveable, and preſerving them from growing reſty and ſtiff.

§. 2.

I have ſometimes alſo, indulg'd a Conjecture, that Animal Food, and Made or Artificial Liquors, in the Original [92] Frame of our Nature, and Deſign of our Creation, were not intended for Human Creatures. They ſeem to me, neither to have theſe ſtrong and fit Organs for digeſting them (at leaſt ſuch as Birds and Beaſts of Prey have, who live on Fleſh); nor, naturally, to have thoſe voracious and brutiſh. Appetites, that require Animal Food, and ſtrong Liquors, to ſatisfy them; nor thoſe cruel and hard Hearts, or thoſe diabolical Paſſions, which could eaſily ſuffer them to tear and deſtroy their Fellow Creatures; at leaſt, not in the firſt and early Ages, before every Man had corrupted his Way, and God was forced to exterminate the whole Race, by an univerſal Deluge, and was alſo obliged (that the Globe of the Earth might not, from the long Lives of its Inhabitants, become a Hell, and a Habitation for incarnate Devils) to ſhorten their Lives from 900 or 1000 Years, to 70. He wiſely foreſaw, that Animal Food, and Artificial Liquors, would naturally contribute towards this End; and indulg'd, or permitted, the Generation that was to plant the Earth again after the Flood, the Uſe of theſe for Food, knowing that tho' it would ſhorten the Lives, and plate a Scourge of Thorns for the Backs [93] of the Lazy and Voluptuous, it would be cautiouſly avoided by thoſe who knew it was their Duty and Happineſs to keep their Paſſions low, and their Appetites in Subjection. And this very Aera of the Flood, is that mentioned in Holy Writ, for the Indulgence of Animal Food and Artificial Liquors, after the Trial had been made, how inſufficient alone, a Vegetable Diet (which was the firſt Food appointed for Human kind, immediately after their Creation) was, in the long Lives of Men, to reſtrain their Wickedneſs and Malice; and after finding, that nothing but ſhortning their Duration could poſſibly prevent the Evil. 'Tis true, there is ſcarce a Poſſibility of preventing the deſtroying of Animal Life, as Things are now conſtituted, ſince Inſects breed and neſtle in the very Vegetables themſelves, and we ſcarce ever devour a Plant or Root, wherein we do not deſtroy innumerable Animalcules. But beſides what I have ſaid, of Nature's being quite altered and changed from what was originally intended, there is a great Difference between deſtroying and extinguiſhing an Animal Life (which otherwiſe might ſubſiſt many Years) by Choice and Election, to gratify our Appetites, [94] and indulge Concupiſcence; and the Caſual and Unavoidable cruſhing of thoſe, who perhaps, otherwiſe, would die within the Day, or at moſt the Year, and obtain but an inferior kind of Exiſtence and Life at beſt. Whatever be in this Conjecture, 'tis evident to thoſe who underſtand the Animal Oeconomy, and the Frame of Human Bodies, together with the Hiſtory, both of thoſe who have lived Abſtemiouſly, and of thoſe who have lived Freely, that indulging in fleſh Meats, and ſtrong Liquors, inflames the Paſſions, and ſhortens Life, begets Chronical Diſtempers, and a Decrepit Age, as the Hiſtory of the Life of Cornaro manifeſts to a Demonſtration.

§. 3.

Of all the Exerciſes that are or may be uſed for Health (ſuch as Walking, Riding a Horſeback or in a Coach, Fencing, Dancing, playing at Billiards, Bowls or Tennis, Digging, Working at a Pump, Ringing a dumb Bell, &c.) Walking is the moſt natural, as it would be alſo the moſt uſeful, if it did not ſpend too much of the Spirits of the Weakly. Riding is certainly the moſt Manly, the moſt Healthy, and the leaſt laborious, and expenſive of Spirits, of [95] any; ſhaking the whole Machine, promoting an univerſal Perſpiration and Secretion of all the Fluids (to which may be added, the various Changes of the Air, thro' which they ſo quickly paſs, every Alteration of which, becomes, as it were, a new Bath) and thereby, variouſly twitching the Nervous Fibres, to brace and contract them, as the new Scenes amuſe the Mind. Thoſe who cannot ride, muſt be carried in a Coach or Litter, which is the beſt Exerciſe for the Lame and Crazy, and the only one proper for Old and Decrepit Perſons, as well as thoſe that are ſo Young, that they are not able to manage their own Exerciſe. The Home Exerciſes, ſuch as playing at Tennis and Billiards, Dancing, Fencing, and the like, ought to be follow'd only when the Seaſon forbids being Abroad; for being in the Air, contributes much towards the Benefit of Exerciſe. 'Tis beautiful to obſerve that earneſt Deſire planted by Nature, in Young Perſons, to romp, jump, wreſtle and run, and conſtantly to be purſuing Exerciſes and Bodily Diverſions, that require Labour, even till they are ready to drop down; eſpecially the healthier Sort of them: So that [96] ſitting or being confined, ſeems to be the greateſt Puniſhment they can ſuffer, and impriſoning them for ſome time, will much more readily correct them than Whipping. This is a wiſe Contrivance of Nature; for thereby, their Joints are render'd pliable and ſtrong; their Blood continues ſweet, and proper for a full Circulation; their Perſpiration is free, and their Organs ſtretched out, by due Degrees, to their proper Extenſion.

§. 4.

It is alſo very agreeable to obſerve, how the ſeveral different Organs of Labouring Men are ſtrengthen'd, and render'd Brawny and Nervous, as they happen to be moſt employ'd in their ſeveral Vocations, let them be otherwiſe ever ſo ſmall or weakly. The Legs, Thighs and Feet of Chairmen; the Arms and Hands of Watermen; the Backs and Shoulders of Porters, grow thick, ſtrong and brawny by Time. 'Tis certain, that ſpeaking ſtrong and loud, without overſtraining, will ſtrengthen the Voice, and give Force to the Lungs. Our Nails and Hair, the more they are cut and ſhaved, the more they grow. And we may promote any one Evacuation ſo far, as to weaken and ſtarve all the reſt. Uſing [97] any Organ frequently and forcibly, brings Blood and Spirits into it, and ſo makes it grow Plump and Brawny. And if due Pains were taken by the Labour proper to them, the Organs of all the Functions of the Animal Oeconomy might be ſtrengthen'd and kept in due plight.

§. 5.

Therefore, to the Aſthmatick, and thoſe of weak Lungs, I ſhould recommend Talking much and loud, even by themſelves, walking up an eaſy Aſcent, and when any degree of Wearineſs warns them, to ſit and reſt, till they are eaſy, and then to return to their walking again, and ſo to increaſe it every Day, till they are able to walk a reaſonable Diſtance, in a reaſonable Time. To thoſe who have weak Nerves and Digeſtion, and to thoſe who are much troubled with Head-aches (moſt of all which ariſe from the ill State of the Stomach and Bowels) I ſhould recommend riding on Horſeback as much as poſſibly they could, in the cleareſt and drieſt Air, and to change the Air daily, if poſſible. To thoſe who are troubled with the Stone or Gravel, to ride much over rough Cauſeways in a Coach. To thoſe that have Rheumatick Pains, to play at Billiards, Tennis or Cricket, [98] till they ſweat plentifully, and then go immediately into a warm Bed, and drink liberally of ſome warm thin Liquor, with Ten Drops of Spirit of Sal Armoniac or Harts horn in each Draught, to encourage the Sweating. To thoſe who have weak Arms or Hams, playing two or three Hours at Tennis, or at Foot-Ball every Day. To thoſe who have weak Backs or Breaſts, ringing a Bell, or working at a Pump. Walking thro' rough Roads, even to Laſſitude, will ſooneſt recover the Uſe of their Limbs to the Gouty; tho' Riding on Horſeback or in a Coach will beſt prevent the Diſtemper. But the Studious and the Contemplative, the Valetudinary, and thoſe of weak Nerves, if they aim at Health and Long Life, muſt make Exerciſe a Part of their Religion, as it is among ſome of the Eaſtern Nations, with whom Pilgrimages, at ſtated Times, are an indiſpenſible Duty, and where Mechanical Trades are learned and practiſed by Men of all Ranks. Thoſe who have their Time in their own Hands, ought to have ſtated Seaſons for Riding or Walking in a good Air, as indiſpenſable, as thoſe for going to Dinner, to Bed, or to Church. Three Hours for Riding, or Two [99] for Walking, the one halſ before the great Meal, and the other before going to Bed, is the leaſt that can be diſpenſed with: As the firſt Part begets an Appetite, the ſecond helps on the Digeſtion. Thoſe who are not Maſters of their own Time, muſt take it when they can; but to be ſure they ought to let no Opportunity of taking it ſlip.

§. 6.

There are Three Conditions of Exerciſe to make it the moſt Beneficial that may be. Firſt, That it be upon an empty Stomach (as, indeed, that is the proper Time for all Medicinal Evacuations) for thereby, the now concocted * Crudities, or thoſe Superſtuities Nature would be rid of, and has fitted, by going through the proper Secretions, for being ejected, but cannot throw off without foreign Aſſiſtance, will be readieſt diſcharged. For, on a full Stomach Exerciſe would be too tumultuous, precipitate the Secretions, and throw off the ſound Juices with the corrupted Humours. Secondly, That it be not continued to down-right Laſſitude, [100] Depreſſion of Spirits, or a melting Sweat. The Firſt will wear out the Organs, the Second ſpend the Strength, and the Third will only do violence to the Natural Functions. Thirdly, Due Care is to be had after Exerciſe, to retreat to a warm Room and proper Shelter from the Injuries of the Weather, leſt ſucking into the waſted Body the nitrous Particles of the circumambient Air, they ſhould inflame the Blood, and produce a Rheumatiſm, Fever or Cold. I might add a Fourth Condition, Joining Temperance to Exerciſe, otherwiſe the Evil will be as broad one Way, as 'tis long the other. For ſince Exerciſe will create a greater Appetite, if it is indulg'd to the full, the concoctive Powers will be as unequal to the Load, as they were before. But I paſs that over, having ſufficiently treated this Subject already.

§. 7.

Under this Head of Exerciſe, I cannot forbear recommending Coldbathing; and I cannot ſufficiently admire, how it ſhould ever have come into ſuch Diſuſe, eſpecially among Chriſtians, when commanded by the greateſt Lawgiver that ever was, under the Direction of God's Holy Spirit, [101] to his Choſen People, and perpetuated to us in the Immerſion at Baptiſm by the ſame Spirit, who, with infinite Wiſdom in this, as in every Thing elſe that regards the Temporal and Eternal Felicity of his Creatures, combines their Duty with their eternal Happineſs. Firſt, The Neceſſity of a free Perſpiration to the Preſervation of Health is now known to every Body, and frequent waſhing the Body in Water, cleanſes the Mouths of the Perſpiratory Ducts from that Glutinous Foulneſs that is continually falling upon them, from their own condenſed dewy Atmoſphere, whereby the Perſpiration would be ſoon obſtructed, and the Party languiſh. Secondly, The having the Circulation, full, free and open, thro' all the Capillary Arteries, is of great Benefit towards Health and Long Life. Now nothing promotes that ſo much as Cold-bathing; for by the violent and ſudden Shock it gives to the whole Syſtem of the Fluids, from the Circumference inward towards the Centre, and the Fluids (becauſe Reaction is always equal and contrary to Action) ſpringing back again from the Centre to the Circumference, a Force is raiſed almoſt ever ſufficient to break thro' all the Dams and Obſtructions of the [102] ſmalleſt Veſſels, where they moſtly happen, and to carry the Circulation quite round. Thirdly, Nothing is ſo injurious, and ſo much prevents the Benefit of Exerciſe to weak and tender Conſtitutions, as ſucking into their Bodies the Nitrous and Humid Particles of the Air, that is, Catching of Cold. Now nothing ſo effectually prevents this, as Coldbathing; as the Nature of the Thing ſhews, and Experience confirms: For if Exerciſe, to attenuate the Juices and ſtrengthen the Solids, be added to Coldbathing, a new Spring and Force will be given to the Blood, both to drive out theſe foreign and noxious Mixtures, and to unite the Cuticular Scales, which form the Scarf-Skin, ſo as to ſtrengthen it for the future againſt ſuch violent Entries.

§. 8.

I ſhould adviſe therefore, every one who can afford it, as regularly to have a Cold Bath at their Houſe to waſh their Bodies in, as a Baſon to waſh their Hands; and, conſtantly, two or three Times a Week, Summer and Winter, to go into it. And thoſe that cannot afford ſuch Conveniency, as often as they can, to go into a River or Living Pond, to waſh their Bodies. But this [103] ought never to be done under the actual Fits of a Chronical Diſtemper, with a quick Pulſe, Head-ach, weak Lungs, or a foul Stomach; nor ought they to ſtay in till they are over-chill'd. And in Winter, they ought to purſue their Exerciſes immediately after they come out; and thoſe of tender Nerves, ought to pour Baſons of Cold Water on their Head, or waſh it well with a dripping Spunge before they go in. I cannot approve the precipitant Way of jumping in, or throwing the Head foremoſt into a Cold Bath; it gives too violent a Shock to Nature, and riſques too much the Burſting ſome of the ſmaller Veſſels. The Natural Way is, holding by the Rope, to walk down the Steps as faſt as one can, and when got to the Bottom, bending their Hams (as Women do when they Curt'ſy low) to ſhorten their Length, ſo as to bring their Heads a good Way under Water, and then popping up again to take Breath; and thus alternately for two or three Times, and out again, rubbing and currying well before they are dreſs'd. And this brings me to ſay ſomething of another kind of Exerciſe.

§. 9.

[104]

The Fleſh Bruſh is an Exerciſe moſt uſeful for promoting a full and free Perſpiration and Circulation; Almoſt every Body knows, what well Currying will do to Horſes, in making them ſleek and gay, lively and active; even ſo much, as to be worth half the Feeding. This it can no otherwiſe effectuate, than by aſſiſting Nature to throw off by Perſpiration, the * Recrements of the Juices which ſtop the full and free Circulation, and by conſtant Friction, Irritation and Stimulation, to allicite Blood and Spirits, to the Parts moſt diſtant from the Seat of Heat and Motion, and ſo to plump up the ſuperficial Muſcles. The ſame Effect it would produce in other Animals, even Human Creatures themſelves, if they were managed in the ſame Manner, with the ſame Care and Regularity. I ſhould think it therefore, well worth the Pains of Perſons of weak Nerves and Sedentary Lives, eſpecially thoſe threatned with Paralytick Diſorders, to ſupply the Want of Exerciſe of other Kinds, with ſpending [105] half an Hour, Morning and Night, in Currying and Rubbing their whole Body, more eſpecially their Limbs, with a Fleſh Bruſh. And 'tis a Wonder to me, that Luxury has not brought Cold-bathing and Currying in Uſe, upon the Animals (eſpecially thoſe of them upon whom they can be ſo readily made Uſe of, ſuch as Oxen, Pigs, Veal, Lamb, and all Poultry, which naturally delight in Cold-bathing) which are brought to the Table. For certain it is, that Cleanneſs and due Exerciſe (of which Currying is one Part) would much contribute, to make all Animals whatſoever, without Exception, healthier in themſelves, fuller of Juice and Spirits, and, conſequently, better Food for Human Creatures.

As to Quiet, the Conditions of Exerciſe being determined, there needs nothing to be ſaid of it.

RULES for Health and Long Life, drawn from the Head Of EXERCISE and QUIET.

[106]
  • 1. WHATEVER was the Original Conſtitution of Man, in our preſent State, a due Degree of Exerciſe is indiſpenſably neceſſary towards Health and Long Life.
  • 2. Animal Food and Strong Liquors, ſeem not to have been deſigned for Man in his Original Make and Frame; but rather indulged, to ſhorten the Antidiluvian Length of Life, in order to prevent the exceſſive Growth of Wickedneſs.
  • 3. Walking is the moſt Natural and effectual Exerciſe, did it not ſpend the Spirits of the tender too much. Riding a Horſeback is leſs laborious, and more effectual for ſuch. Riding in a Coach is only for the Infirm, and Young Children. Houſe Exerciſes are never [107] to be allow'd, but when the Weather or ſome Bodily Infirmity will not permit going abroad; for Air contributes mightily to the Benefit of Exerciſe. Children naturally love all kinds of Exerciſe, which wonderfully promotes their Health, increaſes their Strength, and ſtretches out their Organs.
  • 4. The Organs of the Body that are moſt uſed, always become ſtrongeſt, and therefore we may ſtrengthen any weak Organ by Exerciſe.
  • 5. The Lungs are fortified by loud Talking, and walking up an eaſy Aſcent. The Digeſtion and the Nerves are ſtrengthened, and moſt Head-aches cured, by Riding; the Stone and Gravel eaſed by riding in a Coach over rough Ground; Rheumatick Pains by playing at Tennis, Billiards, &c. till one ſweat, and then going to a warm Bed, to promote the Sweating; Feeble Arms by playing at Shittlecock or Tennis; Weak Hams by Foot-ball, and weak Backs by Ringing or Pumping. The Gouty beſt recover the Uſe of their Limbs by Walking in rough Roads; but prevent the Fits beſt, by Riding a Horſeback, or in a Coach. The Valetudinary, [108] and the Studious, ought to have ſtated Times for Exerciſe, at leaſt Two or Three Hours a Day, the one Half before Dinner, the other before going to Bed.
  • 6. Exerciſe, 1. ſhould always be gone about with an empty Stomach: 2. Should never be continued to Wearineſs: 3. After it, one muſt take Care not to catch Cold. And it ſhould always be accompanied with Temperance, elſe, inſtead of a Remedy, it will become an Evil.
  • 7. Cold-bathing is of great Advantage to Health; but ſhould not be uſed under a Fit of a chronical Diſtemper, with a quick Pulſe, or with a Head-ach, or by thoſe that have weak Lungs. It promotes Perſpiration, inlarges the Circulation, and prevents the Danger of catching Cold. Thoſe of tender Nerves, ſhould pour Water on their Heads before they go in, and none ought to jump in ſuddenly, and with their Heads foremoſt.
  • 8. The Fleſh-Bruſh is a moſt uſeful Exerciſe, as appears by its Advantage to Horſes, and ought not only to [109] be uſed on Human Bodies, but alſo on ſuch of the Animals we deſign for our Food, as it can be applied to.

CHAP. V. Of our Evacuations, and their Obſtructions.

§ 1.

THE Three Principal Evacuations are, By Siege, by Water, and by Perſpiration. All theſe muſt be duly regulated, and in the Order of Nature, towards the Preſervation of Health, and the prolonging of Life. The Firſt ought to be of a due Conſiſtence between both Extremes. * Oportet Sanorum Sedes eſſe figuratas. Thoſe who are coſtive, have either over-heated their Bodies with ſtrong Liquors; have eaten too ſparingly; have too ſlow a Digeſtion, or the Periſtaltick [110] Motion of their Guts are too weak, whereby the Food ſtaying too long a Time before the Mouths of the Lacteals, is over-drained of its Moiſture. Thoſe who have purging Stools, have eat too much, or of Things too ſtrong for their concoctive Powers. For ſuperfluous Nouriſhment leaves too much Chyle in the Faeces, which fermenting in the Guts, ſtimulates them ſo as to become a Purge. I have often obſerved, That a full Meal of ſtrong Meat, as Fiſh, Beef, Pork, Baked Meat, or made Diſhes, in tender Perſons, goes off with the Hurry and Irritation of a Purge, leaving the Bowels inflated, colicked, or griped, and the Spirits ſunk to the laſt Degree. The Food, by its various Mixture, Weight, and Fermentation, ſtimulating all along from the Stomach to the Rectum, and being ſcarce ever drained of its Chyle, without affording any Nouriſhment to the Body, runs off thus crudely, and becomes equal to a total Abſtinence from Food for a long Time. And hence we have a moſt infallible Rule, * à poſteriori, to judge if we have [111] governed ourſelves in our Diet in Proportion to the Neceſſities of Nature, and the Forces of our concoctive Powers. This is the very Reaſon why the Bark over-doſed, and given to Perſons of weak Digeſtion, ſo conſtantly purges them; and why Mercury, given either inwardly, or by Friction, runs off in violent purging, and cannot be raiſed into a Salivation; to wit, the not adjuſting the Doſes to the Strength of the Stomach and nervous Fibres. For the Bark naturally binds, and Mercury naturally riſes to the moſt pervious Glands. And in this Senſe, I myſelf have frequently obſerved in weak and ſcrofulous Bowels, even Diaſcordium, and Venice Treacle to purge: Whereas, had the Doſes been duly proportioned, or had they begun by Underdoſing, and taken a little longer Time, their End might have been effectually anſwered; as I have often experienced without ever failing.

§. 2.

And here it may not be amiſs to take Notice of a fatal Miſtake thoſe run into, who, being weakly, thin, and ſlender, aim, by all Means, and at any Price, to become plump and round, and in order to attain this, are perpetually [112] devouring huge Quantities of high, ſtrong Food, and ſwallowing proportionable Meaſures of generous Liquors, not knowing, that by this very Method, they promote and confirm the Diſeaſe they would remedy; For in ſuch Perſons and Caſes, the globular Part of the Blood is conſtantly of a ſmall Quantity, and very glewy, and the ſerous Part, thin and watry (that is, The Blood is poor and weak) and the Solids or Nerves are looſe and relaxed. And the concoctive Powers being in Proportion to theſe Two, of Conſequence, the Digeſtions muſt be weak and imperfect, and their Force unable to diſſolve and break any Quantity of ſuch ſtrong Meat or ſpirituous Liquors into a proper Chyle for Nouriſhment. And this great Load muſt either be hurried off intirely through the alimentary Ducts in ſupernumerary Diſcharges, or the ſmall Portion of Chyle drawn out of it, being too groſs to unite and make a ſimilar Fluid with the Maſs of the Blood, muſt be precipitated through the other Drains of the Body; and thus the poor thin Creature muſt ſtarve in Luxury, and waſte amidſt Superfluity. The Caſe is the ſame with Nurſes and Parents in rearing up Young Children. The perpetual [113] Gripes, Colicks, Looſeneſſes, hard Bellies, Choakings, Wind, and Convulſive Fits, which torment half the Children of England, are intirely owing to the too great Quantities of too ſtrong Food, and too rank Milk, thruſt down their Throats by their over-laying Mothers and Nurſes. For what elſe do their ſlimy, their gray or chylous, their blackiſh and cholerick Diſcharges, the Noiſe and Motion in their Bowels, their Wind and Choakings, imply, but Crudities from ſuperfluous Nouriſhment? This is ſo certain, that they are univerſally, and infallibly cured by teſtaceous Powders, which only abſorb ſharp Crudities, by Rhubarb Purges, which at once evacuate and ſtrengthen the Bowels, and by Milk-Clyſters, Iſſues, and Bliſters, which are ſtill upon the Foot of Evacuation: by obſtinately perſiſting in theſe, and the like (intended to evacuate and ſtrengthen the alimentary Paſſages) and a thin, ſpare, and nutritive Diet. Nothing nouriſhes but Food duly concocted; and in the Courſe of Nature, we muſt firſt plump up and extend, and then harden and ſtrengthen. This is the Way of Nature in Vegetation. And thus the Animal Creation, devoid of Reaſon, rear up their Young: And thus even [114] the skilful Groom treats his waſted and decayed Horſe: And (which is wonderful) you ſhall find a ſagacious HorſeDoctor plump up and fatten a rotten, lean, broken-winded Jade, and make him look ſleek, gay, and lively, ſo as to cheat not only the Eſquire, but his BrotherDoctor, in fewer Weeks, than all the Man-Doctors in England could rear up their Fellow-Creature, in Years. 'Tis true, The Juices of Men are more variouſly, and more throughly corrupted, and their Solids intirely broken, which never happens to the Brute-Creation. But the greateſt Miſtake lies in the Neglect of duly obſerving, and religiouſly proſecuting a proper Regimen. This muſt principally conſiſt in a Diet of ſoft, light, tender, cool, and mucilaginous Foods, or ſuch as are already become Chyle, either by Nature or Art, ſuch are Milk, and Milk-Meats. Rice, Sago, Barley, Wheat, Eggs, Broths, light Soops, Jellies, white, young, tender, and well-fed Poultry, or Butchery Meat, eaten little at a Time, and often, never without an Appetite, nor to Satiety; joining to theſe, the other Helps and Aſſiſtances mentioned in this Treatiſe. When Fleſh is once come, 'tis eaſy to make it ſtrong and hardy, by [115] due Exerciſe, and a gradual adventuring upon higher Foods, and more generous Liquors.

§. 3.

I have often heard valetudinary, and tender Perſons, and thoſe of ſedentary Lives and Learned Profeſſions, complain of Head-aches, Sickneſſes at the Stomach, Colicks and Gripes, Lowneſs of Spirits, Wind and Vapours, and yet pretend they were very moderate and abſtemious in their Eating and Drinking; But, upon Enquiry, I conſtantly found theſe very Perſons purſued with purging Stools, which was an evident Proof, to me, that they had taken down more than they wanted, or could digeſt. For 'tis univerſally certain, That thoſe that do not exceed, muſt have either Coſtive, or, at leaſt, Stools of a middle Conſiſtence. There is nothing more ridiculous, than to ſee tender, hyſterical and vapouriſh People, perpetually complaining, and yet perpetually cramming; crying out, They are ready to ſink into the Ground, and faint away, and yet gobbling down the richeſt and ſtrongeſt Food, and higheſt Cordials, to oppreſs and overlay them quite. Freſh and generous Food, mixing with the ſharp Humours of the Stomach [116] and Bowels, may, for ſome ſhort Time, qualify and abate their Irritation, and may give a Fillip to the ſluggiſh Circulation, and become, as it were, a Cork to ſtop the perpetual Fuming up of theſe noxious Steams upon the Head and Brain: But this is (pardon the Similitude) as if one ſhould go to quench the peſtilential Steams of a Common-Shore, by throwing in greater Heaps of Ordure and Nuiſance into it. The proper Remedy in this Caſe, is, Firſt, To cleanſe the fetid Abyſs, and then to preſerve it clean by cutting off all the Inlets of Putrefaction. This will require a little Courage, Labour, and Pain; but the future Eaſe and Sweetneſs, will more than abundantly recompenſe them; for there is nothing more certain, than that of thoſe born ſound here in England, the Headaches, Stomach-aches, Colicks, and nervous Pains and Diſorders, univerſally proceed from Idleneſs and Fulneſs of Bread.

§. 4.

Thoſe who eat but one moderate Fleſh Meal a Day, will have regularly once a Day a Diſcharge of the Remains of their Food. And, generally ſpeaking, thoſe that go oftner, have exceeded ſome how. Thoſe who pretend [117] to cure themſelves of nervous Diſorders, or any other chronical Diſeaſes, or preſerve themſelves from them, or lengthen out their Days, muſt underdoſe themſelves (and therefore can go but once in two Days) even though they ſhould undergo the Pain of Coſtiveneſs. For 'tis impoſſible the Nerves of thoſe who have ſlippery Bowels, ſhould ever be braced or wound up; for there the Cure muſt begin, where the Evil began; and muſt be communicated thence to the reſt of the Syſtem, as a Ropemaker begins the Twiſt at one End of the Rope, and communicates it to all the other Parts. Our Acceſs to the Nerves of the Stomach and Bowels, is obvious and open: To the reſt, the Way is difficult, and far about. And ſince a Relaxation, Weakneſs, and want of Spring in the Fibres, is the Origin of all nervous Diſtempers, no Medicines, but ſuch as contract, ſtiffen, wind up, and ſhorten them, can remedy this Evil; and they muſt neceſſarily contract and bind up the Fibres of the Stomach and Guts, as the Parts they firſt approach and exert their Virtue upon. And he, who without firm Bowels, thinks to cure a nervous Diſtemper, labours as much in vain as [118] he who would keep a Fiddle-ſtring ſoaking in Oil and Water, to make it vibrate or play off a fine Compoſition of Muſick.

§. 5.

By Experience and Obſervation I have found, That in thoſe who have one regular Diſcharge in Twenty-four Hours, the Time of the Progreſs of the Food from the Stomach, till its Remains are thrown off, is Three Natural Days. And in thoſe who go but once in Two Days, the Time is Six Natural Days. The Curious may be ſatisfied in this, by ſwallowing an Almond or any other Nut, which paſſes without being broken or making any Irritation. The Reaſon is this, That a ſmaller Quantity of Food is retained longer, by their Suction, at the Mouths of the Lacteals, to drain it intirely of its Chyle, and its Weight being leſs, the Concoctive Powers have the greater Force upon it, and ſo it is retained till it is perfectly Digeſted, and drain'd of all its Humidity; whereby ſuch People become Coſtive: Whereas in People that exceed, the contrary Cauſes precipitate the Courſe of the Aliment, and ſo leave the Bowels always ſlippery. And nothing can more [119] demonſtratively ſhew an Exceſs, than the Lubricity of the Diſcharge; and I have often, obſerved in tender Perſons, and thoſe of weak Nerves, when a Meal (I mean only of thoſe who eat Fleſh Meat only once a Day) has been a little too hard for the Stomach, tho' the Spirits have been full and free, and the Health equal and good, by duly proportioned Meals for two preceding Days; the Third Day, when the groſs Meal came off, they have been full of Wind and Vapours, their Eyes dim, and their Heads heavy, with flying Rheumatick Pains over the Body, and Colick-Gripes. From whence we may draw theſe three Corollaries.

Coroll. 1. It requires the ſame Time for the unconcocted Chyle of a groſs Meal to run the Circle of the Habit, and the feculent Remains to paſs thro' the Guts; the Firſt by Perſpiration, and the Laſt by Siege.

Coroll. 2. We may likewiſe gather from thence, a Confirmation of that Aphoriſm of the Phyſicians; That the Errors of the firſt Concoction, are never mended in the ſubſequent, unleſs the [120] Caſe to be mentioned in the next Paragraph be an Exception to it. For the groſs Meal gave rather more Uneaſineſs, when it came to be thrown off by Perſpiration.

Coroll. 3. From hence we may alſo ſee, the Ridiculouſneſs of the Vulgar Opinion, aſcribing univerſally the Pain they ſuffer, or the Relief they find, to the laſt Meal or Medicine.

§. 6.

There are ſome ſorts of Food which may oppreſs and load the Stomach, and Alimentary Ducts in the firſt Concoction, which may be very ſafe and benign in the ſubſequent ones. For inſtance, Cheeſe, Eggs, Milk-Meats, and Vegetable Food, tho' duly prepared, and juſtly proportioned in Quantity, may chance to lie heavy on the Stomach, or beget Wind in the Alimentary Paſſages of ſome Perſons (and yet drinking of Water will always remedy this Inconveniency): But theſe neither having their Parts ſtrongly united, nor abounding in ſharp Urinous Salts, when they become ſufficiently diluted with a watry Menſtruum, or diſſolved into their Component Parts, and their Parts being ſtill ſmaller than the ſmalleſt Veſſels, and [121] their Union conſtantly leſs, than the Force of the Concoctive Powers, in Perſons who have any remaining Fund of Life in them; will thereby yield a ſweet, thin, and eaſily Circulating Chyle, in the after Concoctions become benign and ſalutary, and afford no Materials for Chronical Diſtempers. And the Wind thence generated, not being pointed and armed with ſuch ſharp Salts, as thoſe of Fleſh Meats, or the Corroſive Juices of Spirituous Liquors, will be as innocent and ſafe, as the Element we breathe in.

§. 7.

The Second Evacuation is by Water, whoſe Circumſtances and Condition, tho' -little adverted to, may be of great Service to diſcover both the State of our Conſtitution, and the Proportion of our Diet. Some People are frightned when they find their Water turbid, broken, and full of Brick-duſt Sediment; whereas that is the beſt Symptom it can have. For tho' it ſuppoſes the Blood loaded with Urinous Salts and Cradities; yet 'tis ſtill better they ſhould paſs off than continue in the Habit. On the contrary, when thoſe that live freely, have Quantities of pale, limpid and ſweet Water, 'tis a certain Sign that the Perſpiration [122] is ſtopp'd; that neither the Firſt nor the Secondary Concoctions have been duly perform'd; that the Chyle has not been ſufficiently broken, nor the finer Secretions duly made by the leſſer Drains; and that the Urinous Salts are ſtill retained in the Habit. Upon which muſt needs enſue Oppreſſion of Spirits, Chills upon the Extremities, flying Rheumatick Pains over the Body, Head-aches, Cholicks and Gripes. And here it may not be amiſs, to take Notice of the Difference of the pale Water of Hypochondriacal and Hyſterical Perſons, from that of thoſe who labour under a true Diabetes, the Apprehenſion of which terrifies ſo often the Low and Diſpirited Perſons of the Firſt Claſs. The Water of both has the ſame Appearance, both in Quality and Quantity, at leaſt, in the firſt Inſtance, they are both attended with the ſame Sinking and Diſpiritedneſs. But in a true Diabetes, there is a conſtant Thirſt, a low but quick Pulſe, the Water is much ſweeter, and continues longer to come off in profuſe Quantities, inſomuch, that ſometimes it is ſo violent as to run down the Party in a few Days. In Hypochondriacal and Hyſterical Perſons, there is little or no Thirſt, never a quick [123] Pulſe, but rather too low and ſlow a one, the Flux ſoon ſtops of itſelf, or by any little Diaphoretick Medicine, and they are cold upon the Extremities, which the others are not.

§. 8.

That bluiſh and variegated Film, which ſometimes looks like Oil and Fat ſwimming on the Water of Scorbutick and Cachectick Perſons, is nothing but the congregated Salts which are crowded ſo thick together, that they are ready to ſhoot into Cluſters, much like the Film of a * Lixivium, when ſtanding for the Cryſtallization of fixed Salts. The Water which has a light Cloud hanging almoſt from the Top to the Bottom, is of a bright Amber Colour, and about three Quarters of the Liquor taken down, is beſt, and a certain Sign of a due Concoction, a juſt Proportion of Food, and a total Abſence of Repletion and Crudity. And thoſe who live Temperately, uſe due Exerciſe, and enjoy a perfect State of Health, always make ſuch Water.

§. 9.

[124]

Thoſe who are ſubject to great Quantities of limpid and pale Water, ought to conclude, that their Food has been too heavy in Quality, or too much in Quantity for their Concoctive Powers, or their Labour too little; and that therefore, they ought to proportion both, for the future, with more Caution and Exactneſs, by living low for ſome Time, or uſing more Exerciſe. And to ſtop their Flux of pale Water, they ought to take a little Gaſcoign's Powder, Confection of Alkermes, or Sir Walter Raleigh's Cordial at Night, and drink liberally of ſmall warm Sack Whey, with a few Drops of Spirit of Hartſhorn, to ſet the Perſpiration in order again. Thoſe, on the other Hand, who make high-colour'd, foul, and very turbid Water in ſmaller Quantities, have either inflamed their Blood too much, with Spirituous Liquors, or loaded it with too great a Quantity of Animal Salts. To prevent therefore Diſorders and Diſeaſes, they muſt leſſen the Quantity of their Fleſh Meat, and temper the Heat of their Wine with Water. Elſe they will lay the Foundation of ſome Acute Inflammatory, or dangerous Chronical Diſtemper.

§. 10.

[125]

The worſt kind of Water of all, is that of a dark Brown or dirty Red, in a ſmall Quantity, and without any Sediment. This kind of Water, in Acute Diſeaſes, always indicates inſuperable Crudity, high Inflammation tending towards Mortification, and a dying Languor in Nature. And in Perſons labouring under no viſible Diſtemper at the Time, an almoſt total Debility of the Concoctive Powers, an inſeparable Union of the Conſtituent Parts of the Blood, the higheſt Degree of Crudity, and a Deadneſs in all the Animal Functions. And, if preceded by long continued Exceſſes, requires the Advice of a Phyſician. I ſhall ſay nothing of Coffee-colour'd, Bloody, Wheyiſh, or Purulent Water, or that with white Gravel, Films, Rags, or Bits of broken Membranes. They are well known to be Nephritick, or Symptoms of an Ulcer ſomewhere in the Urinary Paſſages.

§. 11.

There happens alſo an Evacuation both by Siege and Urine, to ſome weak Perſons of relaxed Nerves, that extremely alarms the Patient, and is not [126] ſo readily accounted for in common * Aetiology. It is when either a white tranſparent, viſcid Subſtance, like Gelly, is conſtantly voided by the Bowels, more or leſs; or when a white, milk, glewy Subſtance, like Cream or laudable Matter, ſettles in the Water: Both theſe Appearances are commonly aſcribed to an Ulcer in the Guts, or in the Kidneys, the very Apprehenſion of which is almoſt ſufficient, in ſome low Perſons, to bring on the Diſtemper feared: And yet I am very certain there is neither Ulcer nor true Matter in either Caſe, as I propoſe them. For where there is violent and acute Pain, or Matter of different Colours or Mixtures, there, very poſſibly, may be, nay, certainly there is, an Ulcer. But in the Caſe I here intend, there is very little or no Pain, no Hectical Paroxyſms, which always attend an inward Ulcer; no bloody or ſanious Mixtures, which always betray the inward Sore; no fetid Smell to imply Corruption. For the Caſes I put at preſent, happen to [127] Perſons the leaſt capable of Inflammation or Impoſthumation, viz. to paralytick Perſons, or thoſe of a Natural Tendency that Way, to cold, vapouriſh Perſons of low Spirits and weak Nerves, whoſe Pulſe is low and ſlow, and their natural Functions weak and languid; all which evidently ſhew, that theſe Diſcharges cannot come from an Ulcer. The firſt Caſe I take to be either an Obſtruction of ſome of the Lacteals, whereby the Chyle cannot be carried off in any ſufficient Quantity, but paſſing through the Guts, and its more Watry Part being evaporated, it becomes thick and gelatinous, and is thrown off at laſt with the Remains of the Food. Elſe it muſt be an Obſtruction of thoſe Glands of the Guts, by which a viſcid Matter for lubricating of them, is commonly ſecerned; by the Impriſonment and Evaporation of which Matter, it thickens and turns like a Gelly (as it does by Cold, or Overfeeding, in the Glands of the Mouth, Throat and Windpipe) and at laſt, by the Squeezing of the Guts, is thrown off. And in the ſame Manner, I take that Milky Subſtance ſubſiding in the Water, in ſuch a Caſe as I have mentioned, to ariſe from [128] a Relaxation of the Glands of the Kidneys and Bladder, and other Urinary Paſſages; and that both are to be cured the ſame Way other Nervous Diſtempers are cured, viz. by a proper Regimen of Diet, and a Courſe of contracting, ſtrengthening, and volatile Medicines.

§. 12.

The inſenſible Perſpiration is the Third Evacuation to be conſidered. The Statical Chair invented by Sanctorius, for examining the Quantity of the Perſpiration, however ingenious and delightful in Speculation, is too cumberſome and laborious to be of any great Uſe in Common Life. 'Tis certain, however, that the free and full flowing of this Evacuation, is as neceſſary to Health as any of the groſſer, ſince in Quantity it is at leaſt equal to both the forementioned; and an Obſtruction thereof, is generally the Source of all acute Diſeaſes, as it is a Conſequence of all Chronical ones. And therefore, I have adviſed thoſe who are much abroad in Eaſterly and Northerly Winds (which moſt of any obſtruct Perſpiration) and have Fluxes of white and pale Water, to a ready Antidote to prevent the Beginnings of theſe Obſtructions.

§. 13.

[129]

Dr. *JAMES KEILL has made it out, beyond all poſſibility of doubting, that catching of Cold is nothing but ſucking in, by the Paſſages of Perſpiration, large Quantities of moiſt Air and nitrous Salts, which by thickening the Blood and Juices (as is evident from Bleeding after catching Cold) and thereby obſtructing, not only the Perſpiration, but alſo all the other finer Secretions, raiſes immediately a ſmall Fever and a Tumult in the whole Animal Oeconomy; and, neglected, lays a Foundation for Conſumptions, Obſtructions of the great Viſcera, and univerſal Cachexies. The Tender therefore, and Valetudinary ought cautiouſly to avoid all Occaſions of catching Cold, and if they have been ſo unfortunate as to get one, to ſet about its Cure immediately, before it has taken too deep Root in the Habit. From the Nature of the Diſorder thus deſcribed, the Remedy is obvious; To wit, Lying much abed, Drinking plentifully of ſmall warm Sack Whey, with a few Drops of Spirit of Hartſhorn, Poſſet-Drink, Water-Gruel, or any other warm ſmall Liquors, a Scruple of Gaſcoign's Powder Morning and Night, Living [130] low upon Spoon-Meats, Pudding and Chicken, and drinking every thing warm: In a Word, treating it at firſt as a ſmall Fever, with gentle Diaphoreticks; and afterward, if any Cough or Spitting ſhould remain (which this Method generally prevents) by ſoftening the Breaſt with a little Sugar-Candy, and Oil of Sweet Almonds, or a Solution of Gum Ammoniac, an Ounce to a Quart of Barley Water, to make the Expectoration eaſy; and going cautiouſly and well cloathed into the Air afterwards. This is a much more natural, eaſy and effectual Method, than the Practice by Balſams, Linctus's, Pectorals, and the like Trumpery in common Uſe, which ſerve only to ſpoil the Stomach, oppreſs the Spirits, and hurt the Conſtitution.

§. 14.

The ſureſt Way of maintaining and promoting a due Perſpiration, is, To take down no more Food than what the Concoctive Powers are ſufficient to reduce into a due Fluidity, and the Expences of Living require, to proſecute neceſſary Exerciſe, and uſe the other Aſſiſtances adviſed in the foregoing Chapters. Want of due Reſt and the Refreſhment that follows upon it, ſtarting, [131] toſſing, and tumbling abed, are certain Signs that the Perſpiration is not duly carried on in the Night Seaſon. And therefore, in order to remedy this, a greater Proportion of Exerciſe, a greater Degree of Abſtinence, or ſome gentle domeſtick Purge, muſt be had recourſe to the next Day. Colical Pains, Gripes and Purging, much Eructation and Belching of Wind, Low Spiritedneſs, Yawning and Stretching, are infallible Signs that the Perſpiration flows not freely and plentifully then. And therefore the ſame Remedies ought to be proſecuted, as ſoon as an Opportunity offers; elſe the Party will ſuffer at laſt. Wind, as Sanctorius obſerves and demonſtrates, is nothing but obſtructed Perſpiration: And Yawning and Stretching, are but Convulſions of the proper Muſcles and Organs appointed by Nature, the one for Pumping up Wind from the Bowels, the other for preſſing upon the Excretory Ducts in the Skin, to force out the ſluggiſh perſpirable Matter. And 'tis beautiful to obſerve, how wiſely Nature has contrived the Spoſms, Cramps and Convulſions of the proper Organs, to expel every noxious and extraneous Body out of the Habit. Thus [132] Coughing is a Convulſion of the Diaphragm and Muſcles of the Breaſt, to throw out viſcid Phlegm; Vomiting, of the Stomach, (aſſiſted by the Diaphragm and Muſcles of the Abdomen) to throw up its Crudities, and thoſe of the Bowels; or to expel Sand or Stones from the Kidneys. The Throws of Labouring Women, are to bring off the Burden. Sneezing is an Effort of the proper Muſcles, to eject ſome noxious Particles from the Organs of Smelling. Shivering and Stretching to aſſiſt Perſpiration; and Yawning to pump up noxious Wind. And even Laughing itſelf, is an Effort of the Muſcles of the whole Trunk, to throw off ſomething that its delicate Membranes cannot bear. And, Laſtly, Hyſterical Fits and Convulſions, both in Infants and Perſons come to Maturity, are but violent Efforts, Struggles, Workings, Cramps and Spaſms of all the Muſcles of the whole Body together, to expel, ſqueeze, and preſs out the ſharp Acrimonious Wind. Fumes and Vapours from the Cavities of the whole Machine.

§. 15.

There is an Evacuation incident to Perſons of weak Nerves, which could not conveniently come in [133] under the general Diviſion, becauſe it happens too ſeldom to make a new Member of it. It is a Diſcharge of thin Rheum from the Glands of the Mouth, Throat and Stomach, and is called by ſome, A Nervous or Scorbutick Spitting. It riſes ſometimes to the Heighth of a petit Flux de Bouche, as the French call it, and threatens ſome tender Perſons, as they apprehend, with a Conſumption, though it imply nothing leſs. We may obſerve ſome, who are ſtruck with a deep Palſey, to flow at the Mouth, and drivel down their Breaſts; inſomuch, that the Afflicted of this Sort, who are advanced in Years, can ſcarce ſpeak intelligibly for the Flux, till they have firſt emptied and cleaned their Mouths. And this ariſes to ſo great a Heighth, in ſome much broken paralytick Perſons, that upon the ſlighteſt Occaſions, either of Joy or Grief, they are apt to run into a Profuſion of Tears, Sighs and Sobbings. And ſome ſorts of Ideots, and thoſe Hyſterically mop'd, and moſt of thoſe who ſuffer from relaxed and weak Nerves, are more or leſs ſubject to theſe Salival Diſcharges, eſpecially after Exceſſes in Diet. Hence the firſt Sort receive the Appellation of Snivellers or Drivellers. [134] And the Difficulty of the Cure of all the Diſeaſes of weak Nerves, depends much on the Quantity and Conſtitution of this Flux. For much and long Spitting and Running off of this Rheum, implies a total Relaxation of the whole Nervous Syſtem, and ſhews neither the firſt nor ſecond Concoctions have been duly performed. I have frequently had Occaſion to ſhew, how Exceſſes in the Quantity or Quality of the Food, in Perſons of relaxed and weak Nerves, begot a viſcid and groſs Chyle, of which that Part, which could not get through the Lacteals, lay fermenting and putrifying in the Alimentary Paſſages, begot Wind, Gripes and Colicks, and at laſt wrought itſelf off like a Purge; and that that Part, which got through the Lacteals, and was received within the Limits of the Circulation, being too groſs and glewy to be mixed with the old Maſs of the Fluids, to circulate through the ſmalleſt Veſſels, and to enter the fine Perſpiratory Glands, would neceſſarily be thrown into the wider, more ſpongy and looſe Salivary Glands, which are appointed by Nature to ſecern the more Glutinous Parts of the Fluids. And from thence this Salivary Inundation [135] proceeds. The Fact is, When thoſe of weak Nerves, commit habitual Exceſſes in their Diet, the Glands and ſmall Veſſels of all the Body are tumified, ſwelled and obſtructed thereby, as they needs muſt be. And 'tis from the Preſſure of theſe inlarged Glands, and the obſtructed capillary Veſſels on the Nerves, and patent Blood Veſſels, that moſt of the Evils they ſuffer under proceed. But more eſpecially, are the Glands appointed to draw off the more viſcid ſerous Part of the Blood, obſtructed and tumified thereby. Upon which Account, as Baglivi adviſes to enquire well into the State of the Tongue and Mouth, in order to diſcover the Condition of the Stomach, Guts and Bowels; ſo I think 'tis highly reaſonable in a Chronical Caſe, to have great regard to the Condition of the Eyes; and if a dead, cold Languor be obſerved in the Hue or Water of them (as Jewellers ſpeak of Diamonds) and more eſpecially if the lachrymal Gland in the Corner next the Noſe, which I always narrowly inſpect; if, I ſay, this Gland be found harder, or larger than ordinary, ſwelled and tumified, it muſt certainly be concluded, whatever elſe be in the Caſe, [136] there muſt be a relaxed State of Nerves, much Vapours, weak natural Functions, and a miſmanaged Regimen. And it is from the Obſtruction and Swelling of this and the other Glands, in and about the Eyes, and their Preſſure upon the Optical Nerves, and fine Blood Veſſels, that thoſe Spots, Flies, Atoms, Dimneſs, Darkneſs, and Confuſion of Sight, in Vapouriſh and Hyſterical People proceed. For this Gland ſhews, that the whole ſerous Glands in the upper Regions of the Body are, in Proportion, tumified and ſwelled with viſcid Humours through Exceſs of Diet; unleſs the Perſon have ſuffered there by Accident, or labours under ſome natural Diſorders of the Eyes. From the Obſtruction and Swelling of the Salivary Glands in the Mouth, Throat and Gullet, proceed alſo thoſe Choakings, Gulping and Strangling, that Hyſterick Perſons ſo often complain of. The Wind and Crudities lodged in their Stomach and Guts, and the reſt of the Cavities of the Body preſſing to get vent upwards, are reſiſted and ſtopp'd in their Paſſage by the Diaphragm, whereby the Inſpiration is ſtreightned, and by the Bulk of theſe Glands throughout the Gullet, the Way is intirely ſtopp'd; [137] which raiſes ſuch a Tumult and Struggle, as produces the mentioned Symptoms; which I have not Leiſure to detail here more minutely. Now this Salivation or Diſcharge of the thinner Rheum, and that Coughing and Hawking of more viſcid Flegm, commonly called a nervous Cough, as alſo the Chincough of Children, and all ſuch Diſcharges of ſharp Serum in Perſons of weak and relaxed Nerves, is an Effort of Nature to relieve them. And, if diſcreetly managed, and duly heeded, would prove a Crise to their Diſorders, and quite free them from their preſent * Paroxyſms, and ſet the Circulation and Perſpiration, and conſequently the Spirits, at Freedom and Liberty again. Some Perſons moſt diſtractedly run to Drams and Cordials to remedy this Evil, to ſtop the Violence of this Deluge, and to raiſe their drooping Spirits. But it ſerves only to thicken the Flegm, ſhut up the Mouths of the Salivary Glands cloſer, and ſo to perpetuate the Evil they mean to cure. Others devour large Quantities of high and generous Foods, becauſe they find a [138] little Relief to their Spirits, from the firſt Run of the ſweet, thin, and ſpirituous Chyle: But this is only adding Fewel to the Fire, and running on in a perpetual Round of Lowneſs and Slavering. Whereas, would they ſuffer Nature to act her own Way, to carry on this critical Diſcharge as far as it will go, without offering in the leaſt either to check or promote it; but by thin, light Food, and cool Liquors, in moderate, or rather under doſed Quantities, ſupport her in the manner the Concoctive Powers are ſufficient for; after ſhe had diſcharged all the Crudities from the Maſs of the Fluids, by theſe Emunctory Glands, and thereby given a free Paſſage to the Wind to eſcape the Way it tends, the Salivation would leſſen gradually, and at laſt ſtop of itſelf. And if then towards the Decline, a gentle Vomit, to pump up the ſlow and viſcid Remains of the Wind and Flegm in the Upper Part of the Alimentary Paſſages, and afterwards a gentle Stomachick warm Purge, to ſcour the Lower Part of theſe Tubes, were carefully adminiſtred; the Patient would ſoon find a clear Head, lightſome Spirits, Eaſe and Freedom from Pain and Oppreſſion; the Circulation and Perſpiration [139] would be ſoon brought to their natural and ſound State, and Health and Cheerfulneſs reſtored together; unleſs a mortal or habitual * Ptyaliſm was the Caſe, which I have ſometimes obſerved, as fatal and incurable as a true Dropſy, or inveterate Diabetes; all which owe their Being to a deep Scurvy, whereby the Globular Part of the Blood is intirely broken, and the Serum made a meer Lixivium or Lye.

RULES for Health and Long Life, drawn from the Head Of EVACUATION.

  • 1. COSTIVE Stools are Signs of over-heated Blood, too ſpare Feeding, Slowneſs of Digeſtion, or Weakneſs of the Guts.
  • 2. Purging Stools ſhew intemperate Feeding. Too full a Meal has the Effects of a Purge, fills the Guts with Wind, and gives Gripes. Mercury, and [140] even the Bark, Diaſcordium and Treacle, if over-doſed, purge.
  • 3. Head-aches, ſick Stomachs, Vapours, low Spirits, Gripes and Colicks, proceed from Cramming; and are ever accompanied with looſe Stools.
  • 4. Thoſe that live temperately, have one regular Stool a Day. Thoſe who have more, exceed.
  • 5. The Cure of all Relaxations of the Nerves (the Source of Chronical Diſeaſes) muſt neceſſarily begin at the Stomach and Guts.
  • 6. The Time from eating a Meal, till its Diſcharge, is three Days, in thoſe that have one Stool a Day: Six in thoſe that have but one in two Days.
  • 7. A groſs Meal produces more Diſorders, the Day the Excrements of it go off, than the Day it is eaten.
  • 8. A Meal takes the ſame Time to get through the Habit by Perſpiration, that its Remains do to paſs through the Guts.
  • [141]9. The Errors of the firſt Concoctions cannot be mended afterwards.
  • 10. Pain or Relief, is not always the Effect of the laſt Meal or Medicine, that was taken down.
  • 11. Though Cheeſe, Eggs, Milk and Vegetable Foods, may be hard to digeſt, without drinking of Water, to ſome Stomachs; yet their Chyle is good, and produces no bad Effects.
  • 12. Turbid Water with Brick-duſt Sediment, proceeds from the critical Diſcharge of what was preternaturally retained in the Habit.
  • 13. Pale ſweet Water, from the Urinous Salts being yet retained.
  • 14. There is great Difference between Hyſterick pale Water, and that which proceeds from a Diabetes.
  • 15. That Appearance of Fat on the Urine of ſome People, is nothing but a thin Film of Salts.
  • [142]16. Bright Amber-coloured Water, with a light Sediment riſing toward the Top, amounting to three Quarters of what is drank, is a Sign of good Digeſtion.
  • 17. Great Quantities of pale Water proceed from Exceſs in the Quantity of Food, and want of Exerciſe. The Cure of it is performed by eating leſs, uſing more Exerciſe, and taking ſome Diaphoreticks, to ſet the Perſpiration right.
  • 18. High-colour'd turbid Water in ſmall Quantity, ſhews abundance of Animal Salts in the Habit, or the immoderate Uſe of Spirituous Liquors: And muſt be cured by vegetable Food, and Water, or other ſmall Drink.
  • 19. Dark brown Water, or of a dirty red, is extremely dangerous, both in acute Caſes, and in thoſe that ſeem at preſent to ail nothing.
  • 20. Bloody purulent Water, and full of Films, is a Sign of Nephritick Ailments, Stone and Gravel.
  • [143]21. The viſcid Matter like Gelly in the Stools, and the viſcid milky Subſtance ſomewhat like Matter in the Urine of ſome People of weak Nerves, proceed from a Corruption of the Liquor of the Mucous Glands of the Inteſtines, and of the Bladder, and other Urinary Paſſages.
  • 22. Obſtruction of Perſpiration is one Source of acute Diſeaſes, and a Conſequence of chronical ones.
  • 23. Catching of Cold is an Obſtruction of Perſpiration, by the humid and nitrous Particles of the Air. It ſhould be cured by gentle Diaphoreticks, and not by Balſamick Pectorals, which do no good but in the End of the Cure, to promote Expectoration from the Lungs, if there be any Occaſion for it.
  • 24. Perſons of weak Nerves, have often a critical Flux of Rheum from the Glands of the Mouth and Throat, to a very large Quantity, which, if not tampered with, brings them great Relief.

CHAP. VI. Of the PASSIONS.

[144]

§. 1.

I Come now, in the Order of my firſt propoſed Method, to treat of the Paſſions; which have a greater Influence on Health and Long Life, than moſt People are aware of. And that I may propoſe my Scheme with the greateſt Clearneſs I can, I will lay down ſome Propoſitions or Axioms, as the Ground-work on which it is founded.

Prop. I. The Soul reſides eminently in the Brain, where all the Nervous Fibres terminate inwardly, like a Muſician by a well-tuned Inſtrument, which has Keys within, on which it may play, and without, on which other Perſons and Bodies may alſo play. By the inward Keys, I underſtand thoſe Means by which the Thoughts of the Mind affect the Body; and by the outward, [145] thoſe whereby the Actions or Senſations of the Body affect the Mind. Both theſe Affections may be called Paſſions in a general View, as either Part of the Compound is acted upon.

Scholium. As a Man is compounded of two different Principles, Soul and Body; and as there are two different kinds of outward Objects, by which theſe two different Principles may be acted upon; to wit. Matter and Spirit; the Paſſions in theſe two different Views may be divided into Spiritual and Animal. As to the firſt Branch of this Diviſion, ſince Spirits (if I may be allow'd there are any ſuch Beings) may be ſuppoſed to act upon one another, without the Mediation of Organical Bodies (ſuch perhaps was St. Paul's Extaſy, when he was rapt up into the Third Heavens; ſuch was Moſes's Commerce with his Maker, when he ſpoke to God Face to Face; ſuch muſt the Influence of the Divine Grace be ſuppoſed; and all who allow of Revelation, admit, that the Soul may be Serene and Tranquil while the Body is in Diſtreſs and Pain; and even all the Stoick Philoſophy is grounded on this Diſtinction) it muſt have a real [146] Exiſtence in Nature. And the other Branch muſt alſo be allow'd by all thoſe, who cannot think Brute Animals mere Machines, and who obſerve, that we have Impreſſions made on our Bodily Organs, which affect us, ſometimes very deeply, even in our Sleep. However theſe Things be, 'tis ſufficient for my Purpoſe, that Man is allowed to be a compounded Being, on which outward Objects may act, to abſtract the Conſideration of the Impreſſions made on the Spirit, from thoſe made on the Body.

Prop. II. The Union of theſe two Principles in the Compound, Man, ſeems to conſiſt in Laws prae-eſtabliſh'd by the Author of Nature, in the Communications between Bodies and Spirits, as there are, no doubt, Laws eſtabliſh'd for Spirits, in their Commerce and Actions upon one another. For every one knows there are Laws of Nature, eſtabliſh'd by its Author, for the Actions of Bodies upon one another.

Scholium. Theſe Laws of the Actions of the Soul on the Body, and of the Body upon the Soul, are never to be known [147] to us, but by their Effects; as the Laws of Nature in the Actions of Bodies upon one another, were firſt diſcovered by Experiment, and afterward reduced into general Propoſitions. One Law of the Action of the Soul on the Body, & vice verſâ, ſeems to be, That upon ſuch and ſuch Motions produced in the Muſical Inſtrument of the Body, ſuch and ſuch Senſations ſhould ariſe in the Mind; and on ſuch and ſuch Actions of the Soul, ſuch and ſuch Motions in the Body ſhould enſue; much like a Signal agreed to between two Generals, the one within, the other without a Citadel, which ſhould ſignify to one another, what they have before agreed to, and eſtabliſhed between them; or like the Key of a Cypher, which readily explains the otherwiſe unintelligible Writing. Beſides theſe Paſſions and Affections, which are involuntary,

Prop. III. As Bodies are purely paſſive, and are acted upon by other Bodies, conformable to the ſettled Laws of Nature; in Spiritual Beings, on the contrary, there is an active, ſelf motive, ſelf-determining Principle, by which it directs and manages itſelf with regard not only to [148] its own ſelf, and its own Sentiments; but alſo to its Actions and Influence on other Beings without it, and their Actions and Influences on it. And this is the Foundation of Liberty, or Freewill, in Rational and Intelligent Beings.

Scholium. That this Faculty or Principle really exiſts, and is eſſential to Spiritual Beings, is as certain, as that there is Motion in the Univerſe, or that Body and Spirit are eſſentially different. For, that Motion is not eſſential to Bodies, is as certain as that Bodies are impenetrable; and that the Quantity of Motion in the Univerſe, may be, and is daily increaſed, is as much Demonſtration as any Propoſition in Euclid. And if Motion be, is, or may be increaſed, it muſt ariſe from Spiritual Beings. And he who can deny this, only ſhews himſelf ignorant of the Principles of all true and juſt Philoſophy, and of the firſt Elements of the Syſtem of material and ſpiritual Beings. For further Conviction of this, and clearing up all poſſible Objections and Difficulties, I refer the Reader to the Learned and Ingenious Dr. Clarke, in his Anſwer to the Enquiry into Liberty, and his Letters to [149] Mr. Leibnitz, where he has treated this Matter with the greateſt Perſpicuity and Juſtneſs. Beſides theſe now mentioned Principles,

Prop. IV. As in Bodies there is a Principle of Gravity or Attraction, whereby, in Vacuo, they tend to one another, and would unite, according to certain Laws and Limitations eſtabliſhed by the Author of Nature: So there is an Analogous Principle in Spirits, whereby they would as certainly, in their proper Vacuity, be attracted by, tend to, and unite with one another, and their firſt Author, Centre, and the Rock out of which they were hewn (to uſe a Scripture Phraſe) as the Planets would to one another, and to the Sun. And this is nothing elſe but what in Scripture is called CHARITY.

Scholium. This Propoſition is as certain as the Rules of Analogy are, which, in my Opinion, are the Foundation of all the Knowledge we can have of Nature, while we can ſee only a few Links of the Univerſal Chain, and but a few disjointed Parts of the grand Syſtem [150] of the Univerſe. The Author of Nature, who could create intelligent Beings only in order to make them Happy, could not leave them to ſo many different Attractions, without implanting into their Eſſence and Subſtance, as an Antidote to ſuch Variety of Diſtractions, an infinite Tendency, Bent and Biaſs towards Beings of the ſame Nature, and towards Himſelf, who was the Cauſe and Object of their Felicity. And even in this our lapſed and forlorn Eſtate, there remain evident Footſteps of this Principle yet un-effaced. Such are the Checks of Conſcience, natural Affection and the univerſal Deſire of Immortality, and Dread of Annihilation; what the World calls the Seeds of Honour and Renown; all that Concern and Regard paid mere Romantick Heroes; and the Worſhip beſtow'd by all Nations, who are not ſunk into mere Brutality, on ſome Superior and Inviſible Powers. Theſe are Remains of this Principle, and its Workings, ſufficient to ſhew its Reality à poſteriori; as the Laws of Analogy, and the Nature and Attributes of the firſt Being, ſhew it à priori. Thoſe who admit of Revelation, cannot doubt of it for a Moment; [151] for * Moſes calls it, A Law engraven on the Heart of Man, and St. Paul, The greateſt Perfection of Human Nature.

Coroll. 1. Hence the true Nature of Supreme Spiritual Good and Evil may be diſcovered. For if there be impreſſed on Spiritual Beings, an infinite Tendency, Bent and Biaſs, to be reunited with their Divine Original, and the Place in the Divine Subſtance out of which they were formed (if I may ſpeak ſo in a Figurative Senſe) then their being finally united with this their Divine Original, is the Supreme Spiritual Good, and the ſeveral Approaches toward this Union, are inferior Spiritual Goods; as the being finally ſeparated from it, is the ſupreme Spiritual Evil, and the ſeveral Steps toward this Separation, inferior Spiritual Evils. And the Means of this Union and Separation, are Moral Good and Evil.

Coroll. 2. By Schol. of Prop. 1. the moſt general Diviſion of the Paſſions, [152] was into Spiritual and Animal. As, in the firſt Senſe, Paſſion may be defined, The Sentiments produced on the Soul by external Objects, either Spiritual ones immediately, or Material ones, by the Mediation of the Organs of the Body: So, in the ſecond Senſe, Paſſion may be defined. The Effect produced by Spirits or Bodies, immediately on the Body. And ſince outward Objects may be conſidered as Goods or Evils, the moſt natural Diviſion of the Paſſions (whether Spiritual or Animal) as they regard theſe Objects, is into the Pleaſurable and the Painful; which exhauſts their whole Extent. And in this Senſe all the Paſſions may be reduced to Love and Hatred, of which Joy and Sorrow, Hope and Fear, &c. are but different Modifications or Complexions, as they may be called. I do not deſcend to a more particular Account, not intending an accurate Treatiſe on the Paſſions, but only to lay a Foundation for ſome general Obſervations on them, as they regard and influence Health and Long Life.

§. 2.

In relation to the Organical Inſtruments of the Body, and the Effects wrought on them, or the Diſorders [153] brought upon them, the Paſſions may be divided into Acute and Chronical, after the ſame Manner, and for the ſame Reaſon, as Diſeaſes are. The acute Paſſions, whether pleaſurable or painful, have much the ſame Effect, and work much after the ſame Manner as Acute Diſeaſes do. They effect a brisk and lively Circulation of the Fluids, criſp up and conſtrict the Solids for ſome ſhort Time. Thus ſudden Guſts of Joy or Grief, Pleaſure or Pain, ſtimulate and ſpur the Nervous Fibres, and the Coats of the Animal Tubes, and thereby give a Celerity and brisker Motion to their included Fluids, for the ſame Time. And the Functions of the Heart and Lungs being involuntary, they have their more immediate Effects upon them. Thus both ſudden Joy and Grief, make us breath ſhort and quick, and make our Pulſe ſmall and frequent. The retaining our Breath for ſome Time (for ſo far our Breathing is voluntary) to reflect more intenſely upon the painful Object, forces at laſt a ſtrong Exſpiration, which becomes a Sigh. Thus a ſudden painful Idea, makes a quicker Circulation of the Blood, and thereby throwing a greater [154] Quantity thereof upwards, through the proportionally larger Branch of the Aorta, makes it appear in the ſuperficial Veſſels of the Face, Neck and Breaſt, and ſo produces a Bluſh; which, when longer continued, and being very ſtrong, is diſperſed over the whole Surface of the Body. Hence the Obſervation of Bluſhing at the Back of one's Hand; and the Reaſons why we ſigh upon ſome Occaſions, and bluſh upon others, depend upon the different Structure of the Organs of Pulſation and Reſpiration. A quick ſurprizing Pain of Mind acts upon the Heart, becauſe the Motion of the Heart is altogether involuntary: So that a ſudden Conſtriction takes place there immediately to increaſe the Pulſe. Whereas we have ſome Power over the Breathing; we can ſtop or ſuſpend it for a Time; and when we are thinking intenſely, our Attention partly makes us hold our Breath, and hence enſues Sighing rather than Bluſhing. For the Pain being ſlow, quickens the Pulſe more gradually: But if it continues long, both Actions of both Organs are reſpectively produced; and hence it comes to paſs, that upon Anxiety, Concern and earneſt Expectation, the [155] Pulſe is found quick and ſmall, and the Breath thick and difficult, as Experience ſhews. The ſame Principles will account for the Effects of Fear and Anger, which make us change Colour, and look red or pale, as the Blood is accelerated or retarded in its Courſe. The ſudden Guſts of theſe Paſſions being thus accounted for, when they become extreme, they drive about the Blood with ſuch a Hurricane, that Nature is overſet, like a Mill by a Flood: So that what drove it only quicker round before, now intirely ſtops it, and renders the Countenance pale and ghaſtly. Sudden and great Fear or Grief, do ſo convulſe the Nervous Syſtem, that ſometimes they alter the Poſition of the Parts, and fix them in a new one. Thus the Hair ſtands on end in a Fright, and the whole Syſtem of the Nerves becomes ſo rigid and ſtiff, as to loſe their Elaſticity; whereby the Animal Functions are ſtopp'd at once; and Fainting, and ſometimes Death, enſues.

§. 3.

The Chronical Paſſions, like Chronical Diſeaſes, wear out, waſte and deſtroy the Nervous Syſtem gradually. Thoſe Nerves which are neceſſary for [156] conſidering, brooding over, and fixing ſuch a Set of Ideas on the Imagination, being conſtantly employ'd, are worn out, broken and impaired. The reſt by Diſuſe, become reſty and unactive, lifeleſs and deſtitute of a ſufficient Flux of warm Blood and due Nouriſhment. And thus the whole Syſtem languiſhes and runs into Decay. Thus ſlow and long Grief, dark Melancholy, hopeleſs natural Love, and overweening Pride, (which is an outragious Degree of Selflove) impair the Habit, by making the proper Seaſons of neceſſary Food and due Labour be neglected, and thereby depriving the natural Functions of their wonted Supplies, overworking ſome Part of the Nervous Syſtem, and leaving the other to ruſt, and become reſty for want of Uſe. Some of theſe Paſſions, as Love, Grief and Pride, when very intenſe and long indulg'd, terminate even in Madneſs. The Reaſon is, as I have been ſaying, becauſe long and conſtant Habits, of fixing one Thing on the Imagination, begets a ready Diſpoſition in the Nerves to produce again the ſame Image, till the Thought of it become ſpontaneous and natural, like breathing, or the Motion of the Heart, which the Machine [157] performs without the Conſent of the Will; and alſo a Diſability or * Tetanus enſues on the other Parts, juſt as the Faquiers in India, fix one or both Hands by long holding them up, ſo as that they cannot bring them down again. There is a kind of Melancholy, which is called Religious, becauſe 'tis converſant about Matters of Religion; although, often the Perſons ſo diſtempered, have little ſolid Piety. And this is merely a Bodily Diſeaſe, produced by an ill Habit or Conſtitution, wherein the Nervous Syſtem is broken and diſordered, and the Juices are become viſcid and glewy. This Melancholy ariſes generally from a Diſguſt or Diſreliſh of worldly Amuſements and Creature-Comforts, whereupon the Mind turns to Religion for Conſolation and Peace. But as the Perſon is in a very imperfect and unmortified State, not duly inſtructed and diſciplined, and ignorant how to govern himſelf, there enſues Fluctuation and Indocility, Scrupuloſity, Horror and Deſpair.

§. 4.

Since the Mind reſides, as has been ſaid, in the common Senſory, like [158] a skilful Muſician by a well-tuned Inſtrument; if the Organ be ſound, duly tempered, and exactly adjuſted, anſwering and correſponding with the Actions of the Muſician, the Muſick will be diſtinct, agreeable and harmonious. But if the Organ be ſpoiled and broken, neither duly tuned, nor juſtly fitted up, it will not anſwer the Intention of the Muſician, nor yield any diſtinct Sound, or true Harmony. Thoſe therefore who are tender and valetudinary, lead ſedentary Lives, or indulge contemplative Studies, ought to avoid Exceſſes of the Paſſions, as they would Exceſſes in high Food, or Spirituous Liquors, if they have any Regard to Health, to the Preſervation or Integrity of their Intellectual Faculties, or the bodily Organs of them. As the Paſſions, when ſlow and continued, relax, unbend, and diſſolve the Nervous Fibres; ſo the ſudden and violent ones ſcrew up, ſtretch and bend them, whereby the Blood and Juices are hurried about with a violent Impetuoſity, and all the Secretions are either ſtopp'd by the Conſtrictions, Cramps and Convulſions begot by them, or are precipitated, crude and unconcocted, and ſo beget, or at leaſt diſpoſe [159] toward Inflammations, Fevers or Mortifications. Hatred, for Example, Anger and Malice, are but Degrees of a Frenzy, and a Frenzy is one kind of a raging Fever. From all which 'tis plain, the violent and ſudden Paſſions, are more dangerous to Health, than the ſlow and continued, as acute Diſeaſes are more deſtructive than chronical.

§. 5.

To ſhew yet farther, the Influence of the Paſſions on the Animal Oeconomy, let us conſider the different Conſtitutions of Men. Thoſe who have very ſpringy, lively, and elaſtick Fibres, have the quickeſt Senſations, a weaker Impulſe producing a ſtronger Senſation in them. Theſe generally excel in the Animal Faculty of Imagination. Hence the Poet,

*Genus irritabile Vatum.

And therefore, your Men of Imagination are generally given to ſenſual Pleaſure, becauſe the Objects of Senſe yield them a more delicate Touch, and a livelier Senſation, than they do others. But if they happen to live ſo long (which is [160] hardly poſſible) in the Decline of Life they pay dearly for the greater bodily Pleaſures they enjoyed in the Youthful Days of their Vanity. Thoſe of rigid, ſtiff and unyielding Fibres, have leſs vivid Senſations, becauſe it requires a greater Degree of Force to overcome a greater Reſiſtance. Thoſe excel moſt in the Labours of the Underſtanding, or the Intellectual Faculties, retain their Impreſſions longeſt, and purſue them fartheſt; and are moſt ſuſceptible of the ſlow and laſting Paſſions, which ſecretly conſume them as chronical Diſeaſes do. And Laſtly, Thoſe whoſe Organs of Senſation are (if I may ſpeak ſo) un-elaſtick, or intirely callous, reſty for want of Exerciſe, or any way obſtructed, or naturally ill-formed, as they have ſcarce any Paſſions at all, or any lively Senſations, and are incapable of laſting Impreſſions; ſo they enjoy the firmeſt Health, and are ſubject to the feweſt Diſeaſes: ſuch are Ideots, Peaſants and Mechanicks, and all thoſe we call Indolent People.

§. 6.

We have before ſhewn, that weak Limbs, and all the bodily Organs, may be ſtrengthened and repaired [161] by proper Exerciſe. And there is no doubt to be made, but the Organs of Senſation, and thoſe the Mind uſes in its intellectual Operations, may be likewiſe improved, ſtrengthened and perfected by conſtant Uſe, and proper Application. And if by Exceſſes, an original bad Conformation, or any Accident, theſe Organs come to be ſpoiled, or by the bad State of the Juices, they be weakned in their Functions; then the Medicinal and Chirurgical Arts may take place, and come in play. But if the Paſſions be raging and tumultuous, and conſtantly fuelled, nothing leſs than He, who has the Hearts of Men in His Hands, and forms them as a Potter does his Clay, who ſtills the Raging of the Seas, and calms the Tempeſts of the Air, can ſettle and quiet ſuch tumultuous, overbearing Hurricanes in the Mind, and Animal Oeconomy. Without ſuch a Miracle, ſince the Soul and Body act mutually upon one another, and the Tabernacle of Clay is the weakeſt Part of the Compound, it muſt at laſt be overborn and thrown down.

§. 7.

In ſuch a wretched Caſe I know no Remedy, but to drown all other Paſſions in that Spiritual one of the [162] Love of God. The Reaſonableneſs and Juſtneſs of which Proceeding, and (what may ſeem a Paradox) the Uſefulneſs of it to Health, and its benign Influence on the Animal Oeconomy, I ſhall endeavour to demonſtrate. Spiritual Love is that Principle analogous to Attraction, ſpoken of in Prop. IV. 'Tis the Tendency, Byaſs or Impulſe of the Minds of Men and other Spirits, toward the moſt amiable Objects, communicated by their Creator in their original Formation, by virtue of which, they conſtantly tend, preſs and urge to unite (and, if Obſtacles were removed, would unite) with one another, and be all united with their Origin. This Principle indeed, in this lapſed Eſtate of Man (where 'tis overlaid and buried under Rubbiſh, involved in ſo many other Attractions, and ſtifled with ſuch Letts and Contrarieties, that its Action is felt but juſt enough to know that it is, and wants to be a waked with Labour, and excited with Violence, as the Scripture mentions, the taking the Kingdom of Heaven by Force) on its firſt Developement and Expanſion, and in its firſt Exerciſes, may be called a Spiritual Paſſion, as 'tis the firſt Motions, Endeavours and Velleities toward the Love [163] of God or Charity. But in its Advances, and final Perfection and Conſummation, it diſcovers itſelf to be a Faculty, Quality, or inherent Power in the Soul, whereby it will act without Solicitation, Motive or Direction. As a Stone in a Wall, faſtened with Mortar, compreſſed by ſurrounding Stones, and involved in a Million of other Attractions, cannot fall to the Earth, nor ſenſibly exert its natural Gravity, no, not ſo much as to diſcover there is ſuch a Principle in it; juſt ſo, the intelligent Soul, in this her lapſed Eſtate, being drowned in Senſe, chained and fettered by Ignorance and Perverſeneſs, drawn and hurried away by the Devil, the World and the Fleſh, is diſabled from exerting this inherent and innate Principle of Re-union, and wants ſufficient Light on the Underſtanding, and a right Turn of the Will, to be put in a Capacity of exerciſing it. But in its proper Vacuity, and being freed from theſe Letts and Impediments, it would mount towards its Original, like an Eagle toward the Sun. Amiability, Pulchritude or Beauty, is as much the peculiar and proper Object of this Affection of the Mind, as Light or a luminous Body is of Viſion; for Deformity, [164] as ſuch, can never be loved. And Beauty or Perfection, is, in Reality and juſt Philoſophy, nothing but Analogy, Order, or juſt Proportion. From hence it neceſſarily follows, that in the Scale of Beings, all Objects ought to be loved in proportion to their Degree of Beauty, Symmetry or Perfection. And conſequently, the higheſt Perfection ought to be loved with the higheſt Degree of Love, and the ſeveral ſubordinate Degrees of Perfection, with proportionate Degrees of this Affection of the Mind. And ſince Finite, when compared with Infinite, evaniſhes quite, or becomes nothing; it follows neceſſarily (ſince there is, and can be, but one Object that is Infinite, Good and Perfect, and all others are but Created, and Finite Goods; that is, in Compariſon they are nothing) that, according to the eternal and immutable Laws of Analogy, the One ſupreme Good, endued with Infinite Perfection, ought to be loved with a Love infinitely ſuperior to our Affections for other Things, or (which is the ſame Thing in other Words) that, in Compariſon, our Love to the Author of our Being, ought to be infinite; and that to ourſelves and other Objects, as [165] being finite Creatures, none at all. This is the true Philoſophy of this Matter, and as much a Demonſtration, as any thing in Numbers or Geometry poſſibly can be; however it may be received by Men of Self-Love and Carnal Minds.

§. 8.

Yet I would not be ſo underſtood, as if I condemned all ſubordinate and duly proportioned Regards for ourſelves and other Objects about us, that are neceſſary for our Support and Accommodation in our preſent State. No! There is a juſt and laudable Self-love, as well as a falſe and vitious one. If we love Ourſelves, as we love our Neighbours; if we love Ourſelves as God loves us; if we love Ourſelves as we deſerve to be loved by the infinitely perfect Being; if we love Ourſelves with a juſtly proportioned, and duly ſubordinate Love: that is, if we love Ourſelves with a Finite, and Him with an Infinite Love, or a Love increaſing, and going on in infinitum, that has neither Limits nor End: Then we love Ourſelves as we ought; this Self-love is juſt and laudable, and has its due and proper Degree of Reality and Exiſtence, in the Nature of Things. Perfection, or [166] an Object perfect in its kind, or one that we think ſo, is the proper Object of our Love. And as in due Analogy, Proportion and Order, infinite Perfection, requires infinite Love, or the higheſt Degree of Love we can give it; ſo all other Objects are to be loved with a Degree of Love proportioned to their Perfection. And ſince a Being of infinite Perfection can be but one, and all other Beings can have but a finite Degree of Perfection, we muſt love them but with a finite Love; or, the Proportion of our Love to Him and them, ought to be, as Infinite is to Finite. That is, comparatively we ought to love them with no Love at all; but abſolutely (or without comparing created Things, to the infinitely perfect Being) with their proper Degree of finite Love, according to their Rank in the Scale of Beings.

Coroll. Tho' from the Nature of the Demonſtration I have given, that God is to be loved, it is evident he is to be loved infinitely for Himſelf, and his own infinite Perfections, abſtracting from all other Conſiderations, even that of our own Happineſs, in the Enjoyment of, or [167] Union with Him; Yet it is certain, theſe Two, our Love to God, and our own Happineſs, cannot be actually ſeparated. Pleaſure conſiſts in this, That the Soul and Body are affected, by the Objects that produce it, with an harmonious and commenſurate Action or Touch; for in their original and uncorrupted Make, as they came from the Hands of their Creator, both ſeparately, and each by themſelves, and alſo in their Actions on one another, all was Harmony and Concord. As to the Body; as nothing but a muſical or commenſurate Touch, can affect it with Pleaſure, and as a diſcordant and uncommenſurate Stroke creates a Jarring, Grating and Obſtruction, which is Pain (this is evident in Hearing, where the agreeable Senſations of ſonorous Bodies, are altogether harmonious; Sir Iſaac Newton, has made it plain in Viſion; And, no Doubt, it is ſo in all the other Senſes) So likewiſe as to the Soul; Truth, and Beauty or Perfection, are the only Objects, that give Pleaſure to the Underſtanding and Will, its two Cardinal Faculties. And theſe are nothing but Harmony, or juſt Proportion in the reſpective Objects. And we have ſhewn, [168] that the Union of the Soul and Body (or Life, the ſo much coveted Good) conſiſts in a kind of Harmonia praeſtabilita (though a kind very different from Mr. Leibnitz's) whereby an harmonious Touch or Action upon either of them, produces a pleaſurable Senſation. Now as Beauty or Perfection gives Pleaſure to both the Parts of the Compound, and as nothing but the higheſt Degree of Perfection or Beauty, can give the greateſt Pleaſure, i. e. Happineſs; it neceſſarily follows, That Spiritual Love, or the Love of God, as it is the only Mean of uniting us with the one Being, who is infinitely perfect, is alſo the only Mean of making us infinitely happy.

§. 9.

As to the ſecond Thing propoſed, concerning Spiritual Love, however foreign theſe metaphyſical Speculations concerning it may ſeem, to a Diſcourſe about Health and Long Life; yet, if ſteadily believed, and their natural Conſequences reduced to Practice, they would not only become the moſt effectual Means to prevent Diſeaſes, but alſo, the moſt of any Thing, promote Health and Long Life. For, firſt, Were our Love proportioned to the Order and [169] Analogy of Things; were our Love to the Supreme Good infinite, and that to others, in Compariſon, none at all; we ſhould have but one ſingle View in all our Thoughts, Words and Actions viz. The Promoting and Raiſing that ſupreme Love, to its due Degree and Elevation: whereby all Anxiety, carking Care, and Solicitude about other Things (the Source of all our Miſeries, and of many Bodily Diſeaſes) would be cut off all at once. Secondly, Since Love always begets Reſemblance of Manners; ſince the Object of this Love is infinitely perfect; if we loved him in the ſupreme Degree, we ſhould infinitely endeavour to reſemble him: whereby Hatred and Malice, Luxury and Lewdneſs, Lazineſs, and all the other Seeds of Bodily Diſeaſes, would be altogether deſtroyed. Thirdly, Since Spiritual Love is not only the nobleſt, but alſo the moſt joyful and pleaſant Affection of the Mind; ſince the Object of our ſupreme Love (as an inſpired Poet expreſſes it) has Fulneſs of Joy in his Preſence, and Rivers of Pleaſures at his Right Hand for ever; and ſince our Joy and Happineſs will always riſe in proportion to our Love; the placing our ſupreme Love on the ſupreme Good, [170] would render us infinitely joyful, ſerene, calm and pleaſed; than which, certainly, no Man can imagine a more effectual Mean of Health and Long Life.

RULES of Health and Long Life, drawn from the Head Of the PASSIONS.

  • 1. THE Paſſions have a greater Influence on Health, than moſt People are aware of.
  • 2. All violent and ſudden Paſſions, diſpoſe to, or actually throw People into acute Diſeaſes; and ſometimes the moſt violent of them bring on ſudden Death.
  • 3. The ſlow and laſting Paſſions, bring on chronical Diſeaſes; as we ſee in Grief, and languiſhing hopeleſs Love.
  • 4. Therefore the ſudden and acute. Paſſions are more dangerous than the ſlow or chronical.
  • [171]5. Men of lively Imaginations and great Vivacity, are more liable to the ſudden and violent Paſſions and their Effects.
  • 6. Thoughtful People, and thoſe of good Underſtanding, ſuffer moſt by the ſlow, and ſecretly conſuming Paſſions.
  • 7. The Indolent and the Thoughtleſs, ſuffer leaſt from the Paſſions: The Stupid and Ideots not at all.
  • 8. The Diſeaſes brought on by the Paſſions, may be cured by Medicine, as well as thoſe proceeding from other Cauſes, when once the Paſſions themſelves ceaſe, or are quieted. But the preventing or calming the Paſſions themſelves, is the Buſineſs, not of Phyſick, but of Virtue and Religion.
  • 9. The Love of God, as it is the ſovereign Remedy of all Miſeries, ſo, in particular, it effectually prevents all the Bodily Diſorders the Paſſions introduce, by keeping the Paſſions themſelves within due Bounds; and by the unſpeakable Joy, and perfect Calm, Serenity and Tranquillity [172] it gives the Mind, becomes the moſt powerful of all the Means of Health and Long Life.

CHAP. VII. Containing thoſe OBSERVATIONS, that came not naturally under the foregoing Heads.

§. 1.

MENTION having been ſo often made of Chronical, and ſometimes of Acute Diſtempers, it may be convenient here, to ſuggeſt to the Readers, as clear an Account of their Nature and Difference, as I poſſibly can. Acute Diſtempers, then, are underſtood, Such as within ſome ſhort limited Time have their Periods, either of a perfect Criſe, and ſubſequent Recovery, or of putting an End to the Diſtemper and Life both together; and are therefore called [173] quick, ſharp or acute Diſtempers, whoſe Symptoms are more violent, their Duration ſhorter, and their Periods more quick, either of ſudden Death, or a glorious Victory over the Diſeaſe. Theſe are generally limited within Forty Days. And thoſe that run out longer, turn into chronical Diſtempers, whoſe Periods are more ſlow, their Symptoms leſs ſevere, and their Duration longer. They too (if new Fuel were not adminiſtred to them) would, by the Courſe of Nature, and the Animal Oeconomy, have their Periods, and terminate at the laſt. The Viſcidity of the Juices, and the Flaccidity of the Fibres, would, in a great meaſure, and to ſome very tolerable Degree, by proper Remedies, and a due Regimen, be removed, and the Party recover in theſe, as well as acute Caſes. But this requiring long Time, much Care, and great Caution, unwearied Patience and Perſeverance, and ſo long a Courſe of Self-denial, as few People are willing to undergo, it is become the Reproach of Phyſick and Phyſicians, that acute Caſes cure themſelves (or rather Nature cures them) and chronical Caſes are never cured. But both the Branches of the Reflexion [174] are equally falſe. In the Firſt, Art and Care, judiciouſly applied, will always alleviate the Symptoms and Suffering, will help on Nature to the Relief ſhe points out, and quicken the Criſe, which it will conſtantly bring about, if the Diſtemper is not too ſtrong for the Conſtitution. And even then it will mitigate the Pain, and lay the Patient gently and eaſily down. But in the laſt Caſe, if due Care be had, to follow timeouſly the Advice of an honeſt and experienced Phyſician, a Period certainly may be brought about to moſt chronical Diſtempers, where the great Viſcera are not ſpoiled and deſtroyed. The Failing is in the Patient himſelf, who will not, or cannot, deny himſelf for a Time ſufficient to bring about the Cure. Some chronical Diſtempers indeed are ſuch, either by having gone too far, or by being Hereditary, and interwoven with the Principles of Life, as never to be totally overcome. And then 'tis a Piece of great Wiſdom, to know how far their Conſtitution will go, and ſit down contented with that meaſure of Health their original Frame will admit of. But of this I am morally certain, If the Rules and Cautions laid down in this Treatiſe, [175] be carefully, ſteadily, and conſtantly obſerved, few chronical Diſtempers but will receive ſuch Relief and Alleviation by them, as to make Life tolerably eaſy, and free from grievous Sufferings: And in the mentioned Caſe, that is all that is left for Art to do. But in other chronical Diſtempers taken in due Time, where the Viſcera are not quite ſpoiled, they would infallibly bring about a final Period, and perfect Cure. The moſt certain diſtinguiſhing Mark of an acute Diſtemper, is, To have a quick Pulſe; that of a Chronical, To have a ſlow one. The firſt will exhauſt the Fluids, and wear out the Solids in a ſhort Time; whereas the laſt will require a longer Time to produce the ſame Effect. Some chronical Diſtempers, eſpecially towards the laſt and fatal Period, turn acute. And ſome acute ones terminate in chronical Diſtempers. But this Mark will not only keep them diſtinct; but alſo point out, when acute Diſtempers have chronical Remiſſions or Intermiſſions, and when chronical Diſtempers have acute Fits or Paroxyſms.

§. 2.

Some Perſons, who are extremely healthy and ſound during [176] their younger Days, about, or ſoon after the Meridian of Life (that is, about Thirty-five or Thirty-ſix, according to the Obſervation of an inſpired King) fall into chronical Diſtempers, which cut them off in few Years, or make them miſerable all the reſt of their Lives. Thus Conſumptions prove mortal to ſome about that Time. Thus Stone and Gravel, Gout and Rheumatiſm, Scurvy and Dropſy, King's-Evil and SkinDiſeaſes, either make their firſt Appearances, or ſhew themſelves in their true Type about this Time of Life. The Reaſon is, While the Juices are ſweet, ſufficiently thin and fluid, but eſpecially while the ſolid Organs, the Membranes and Fibres, are yet but unfolding; ſtretching and drawing out to their full Dimenſions; any Acrimony, Sharpneſs, or corroding Humour, can affect them no other Way, than by making them vibrate, and ſo extend themſelves farther and farther. For as Pain, ſo theſe ſharp Salts by their Twitching and Irritation on the tender Fibres, make them only contract, and ſo draw at both Extremities, and thereby unfold and extend themſelves farther. So while the original Foldings and Complications of [177] the Solids are not yet quite extended, this Irritation ſerves only to draw them out, and does not hurt them, till they are arrived at their full Extent, which generally happens about Five-andtwenty. It takes a due Time after that for theſe ſharp Humours to exalt themſelves to their utmoſt Acrimony, to corrupt and putrify the Juices, and alſo ſome more Time to wear out, to obſtruct and break the great Organs, and their ſmaller capillary Veſſels. The Sum of all which, brings the Periods of the great Attacks of theſe Diſtempers to the mentioned Time of Life. Thoſe in whom the original Taint is deeper and more radicated, and the natural Conſtitution weaker, ſuffer under theſe Attacks ſooner. And thoſe in whom it is ſlighter and more ſuperficial, and whoſe Complexion is ſtronger and more hardy, hold out longer. But the Generality ſuffer firſt, eminently, about the Meridian of Life. Hence the common Obſervation of thoſe that die of a genuine Conſumption, that they begin to feel it firſt before Thirty-ſix.

§. 4.

There is no chronical Diſtemper whatſoever, more univerſal, more obſtinate, [178] and more fatal in Britain, than the Scurvy, taken in its general Extent. Scarce any one chronical Diſtemper but owes its Origin to a Scorbutick Cachexie, or is ſo complicated with it, that it furniſhes its moſt cruel and moſt obſtinate Symptoms. To it we owe all the Dropſies that happen after the Meridian of Life, all Diabetes, Aſthma's, Conſumptions of ſeveral kinds, many ſorts of Colicks and Diarrhaea's, ſome kinds of Gouts and Rheumatiſms, all Palſies, various kinds of Ulcers, and, poſſibly, the Cancer itſelf, and moſt cutaneous Foulneſſes, weakly Conſtitutions, and bad Digeſtions, Vapours, Melancholy, and almoſt all nervous Diſtempers whatſoever. And what a plentiful Source of Miſeries theſe laſt are, the Afflicted beſt can tell. And ſcarce any one chronical Diſtemper whatſoever, but has ſome Degree of this Evil faithfully attending it. The Reaſon why the Scurvy is ſo * endemick a Diſtemper, and ſo fruitful of Miſeries, is, that it is produced by Cauſes moſtly ſpecial and particular to this Iſland; to wit, The indulging ſo much in animal Food, and ſtrong fermenting Liquors, in contemplative Studies, and ſedentary Profeſſions [179] and Employments (and thence the Want of due Labour and Exerciſe) together with the nitrous Moiſture of an Iſland, and the Inconſtancy and Inclemency of the Seaſons thence ariſing. I have had many Occaſions to ſhew, how ſuch Cauſes muſt neceſſarily and naturally produce ſuch Effects. I will here only touch the Matter ſlightly, to point out the Connexion. Animal Foods and ſtrong Liquors to Exceſs, and with Continuance, muſt load and charge the Fluids with their Salts. Want of due Exerciſe muſt ſuffer theſe to unite in Cluſters, and increaſe their Bulk in the ſmall Veſſels. Their larger Bulk, and greater Acrimony, thence ariſing, muſt increaſe the Viſcidity of the Fluids, by breaking the Blood Globules, and ſo coagulating the Maſs, and at laſt obſtruct the finer Pipes, and all the ſmaller Glands: Whereby the Tone of all the elaſtick Fibres muſt be interrupted and broken, and their Vibrations ſtopt at every obſtructed Gland and capillary Veſſel, and an univerſal Diſorder produced in the whole animal Oeconomy. And this Diſorder will operate, and ſhew it ſelf in Symptoms ſpecial and particular, according to the ſpecial and particular Make and [180] Conformation of the Parts, the Weakneſs or the Strength of the Organs, the particular Miſmanagements, and preciſe State of the Air the Party lives in. And the Detail of theſe general Cauſes applied to particular Perſons, muſt produce the reſpective Diſeaſes mentioned. In a Word, The Scurvy is a kind of Catholick Diſtemper here in Britain, ariſing from conſtant and general Cauſes, from the Cuſtoms of the People, and from the Nature of the Climate, which renders the ſerous Part of the Blood too thick and glewy, breaks and divides the Union of the globulous Parts, obſtructs the ſmall Veſſels, and deſtroys the Springineſs and Elaſticity of the Fibres. So that moſt chronical Diſtempers, can be little elſe, but Branches and Cions from this Root, which (like Pandora's Box) is ſo fruitful of Variety of Miſchiefs. And its ariſing from the Climate and Cuſtoms of the People, is the Reaſon why chronical Diſtempers are ſo frequent in Britain, to what they are in warmer Climates (which, by a freer Perſpiration and lighter Diet, not only prevent thoſe Diſeaſes in their own Inhabitants, but univerſally cure thoſe of our Iſland who are afflicted with them, [181] if they flee to thoſe Regions any reaſonable Time before Nature be quite worn out.) For though the Inhabitants of Britain, live, for the moſt part, as long, or rather longer than thoſe of warmer Climates; yet ſcarce any one, eſpecially thoſe of the better Sort, but becomes craſy, and ſuffers under ſome chronical Diſtemper or other, before they arrive at old Age. The ſame Reaſon is to be aſſigned for the Frequency of Self-murders here, in England eſpecially, beyond any other Country. For few have Grace and Reſignation enough, to ſuffer patiently the laſting Pains of a chronical Diſtemper, or the yet more torturing and crucifying Anguiſh of a perpetual Diſpiritedneſs; though I have obſerved generally, and have good Reaſon to conclude univerſally, That all Self-murderers are firſt diſtracted and diſtempered in their intellectual Faculties. Notwithſtanding the Diffuſiveneſs and Univerſality of this Diſeaſe, ſo that ſcarce a ſingle Individual of the better Sort is altogether free from it; yet I never once in my Life, ſaw it totally extirpated in thoſe who had it to any Degree, ſo as to be intirely free from it all the reſt of their Lives after; but that it ſtill appeared, [182] and ſprang up again in ſome Symptom or other, and at laſt brought forth that grand one, which put a final Period to all their Sufferings. One good Reaſon for this is, That it requires a Regimen and Conduct ſo intirely contrary and oppoſite to the natural Habits and Cuſtoms, and the univerſal Bent and Appetites of the Inhabitants of this Iſland, that it becomes a kind of perpetual Self-denial to them; which the Britiſh Nation, in general, does not mightily admire. Another Reaſon is, That fine Folks uſe their Phyſicians, as they do their Laundreſſes, ſend their Linen to them to be cleaned, in order only to be dirtied again. Nothing leſs than a very moderate Uſe of animal Food, and that of the Kind which abounds leaſt in urinous Salts (as moſt certainly the young and the lighter-coloured do) and a more moderate uſe of Spirituous Liquors, due Labour and Exerciſe, and a careful guarding againſt the Inconſtancy and Inclemency of the Seaſons, can keep this Hydra under. And nothing elſe than a total Abſtinence from animal Foods, and ſtrong fermented Liquors, can totally extirpate it. And that, too, muſt be begun [183] early; before, or ſoon after the Meridian of Life; or elſe there will remain too little Oil in the Lamp, the Spirits will ſink too far, ever to be recovered again; and the remaining Part of Life, will be too ſhort for ſo total a Change as muſt be made. So that thoſe who ſuffer greatly under this Britiſh Diſtemper, muſt be contented to bear and forbear, a little, and muſt expect no greater Degree of Health, than their Time of Life, the Nature of their Diſeaſe, and the State of their Conſtitution will admit of. But ſtill a great Moderation in animal Foods, and ſpirituous and fermented Liquors, due Exerciſe, and a Care to fence againſt the Injuries of the Weather, will make Life tolerably eaſy; eſpecially if ſome gentle domeſtick Purges be interſperſed. The Seeds and young Sprouts of Vegetables, have ſcarce any groſs, fix'd, or eſſential Salts at all in them. This is not only evident from the Reaſons formerly given (becauſe they are young, or the Nouriſhment appointed by Nature for young Vegetables; for the Earth is only a proper Neſt or Matrix for them; and the Sun's Heat ſerves them inſtead [184] of Incubation) but upon * Trial and Examination, they yield none, being too light and thin to calcine and incinerate, and the Salts too volatile (and conſequently, ſmall and fit to paſs by Perſpiration, and thereby can be no way injurious to Human Conſtitutions) to endure the Fire; which full-grown Plants, their Stalks and Wood, readily do. And in unfermented Liquors, the Salts are ſo enveloped, that they cannot unite to form a Spirit, and are ſo ſheathed, by particular Coats of the Materials of the Vegetable, that they can ſcarce do any harm (except when they exceedingly abound) to animal Bodies. Hence it comes to paſs, that a vegetable Diet for a few Weeks or Months, together with drinking Water or unfermented Liquors (ſuch as Tea, Coffee, Barley-Water, Liquorice-Water, Teas made of Oranges, or other Seeds and Plants) will faſten the Teeth when dropping out, from a Conſumption of the Gums by ſcorbutick Salts, cure any cutaneous Foulneſſes or Eruptions, and even any ſpreading Ulcer, if it is not Scrofulous, when no [185] Medicine on the Face of the Earth will touch it. Hence the grand Maxim in the Cure of all Ulcers is, by Diet to bring them to the State of a Wound, and then they will cure of themſelves. And, as I have elſewhere obſerved, there is ſcarce a thin, conſumptive, hyſterick or hypochondriack, and weakly Conſtitution in England, which has not for its Parent, a latent or manifeſt ſcorbutick Cachexy, excepting that which ariſes from a Scrofula. From the whole we may gather, how much a proper Regimen of Diet and due Exerciſe, with the other Helps and Remedies already mentioned in this Treatiſe, is able to do in moſt Britiſh chronical Diſtempers.

§. 4.

Having had ſo often Occaſion to ſpeak of weak and relaxed Nerves, it will not be amiſs to ſuggeſt, ſome of the outward and moſt ſenſible Signs and Characters, whereby it may be manifeſt, whether one's ſelf, or any particular Perſon he is concerned for, be of this Make and Conſtitution, before ſome chronical Diſtemper, or other diſmal Symptom has made it plain; in order to prevent theſe as far as poſſible. To which purpoſe we muſt obſerve, that the Nerves are [186] Bundles of ſolid, ſpringy, and elaſtick Threads or Filaments (like twiſted CatGuts or Hairs) whoſe one Extremity is terminated at the common Senſory in the Brain, where the Soul is ſuppoſed to reſide; the other is interwoven into every Point of the Scarf-skin, the Membranes, the Coats of the Veſſels, the Muſcles and the other ſenſible Solids of the Body, in order to convey the Motions, Actions, Vibrations or Impulſes of outward Objects to the Soul. Theſe Threads or Filaments are highly elaſtick or ſpringy, as we may ſee from their hardned Subſtances, ſuch as Whalebone, Ivory, Horn and Cartileges, which are more eminently ſo than any other Bodies known. Some Perſons have their Fibres very quick, readily vibrating, highly ſpringy and elaſtick, ſo as to tremble and ſhake violently, by the leaſt Impulſe. Others have more rigid, firm, and ſtretched Fibres, which yield not but to ſtrong Impreſſions, and move ſlowly, but move for a long Time. Laſtly, There are thoſe who have weak, looſe, ſlender and relaxed Fibres, which though eaſily moved, and yielding to the weakeſt Impulſe, yet communicate only imperfect, languid and faint Impreſſions and Vibrations to [187] the Soul, and have all their other Animal Functions of the ſame languiſhing Nature. And 'tis of theſe laſt, I have been all along ſpeaking. And we may readily diſcover them, by theſe outward Characters and Signs. 1. Thoſe who have naturally ſoft, thin, ſmall and ſhort Hair, are of a looſe, flabby, and relaxed State of Nerves. For the Hair ſeems to be ſome of the fleſhy Fibres, only lengthen'd outwards and harden'd. At leaſt, like the Fibres, they conſiſt of a great many leſſer Filaments contained in a common Membrane, are ſolid, tranſparent and elaſtick: And as theſe Hairs are in Strength and Bulk, ſo generally the Fibres of the Body are. 2. Thoſe of the faireſt Hair, are of the looſeſt Fibres (other Things being equal) becauſe the Faireſt are more rare, porous and fungous; And becauſe Bodies of the lighter Colours, conſiſt of ſmaller Parts, than thoſe of the more flaming Colours; as has been formerly obſerved. 3. Thoſe of large or (as they are called) maſtiff Muſcles. and of big Bones, are generally of a firmer State of Nerves, than thoſe of little Muſcles and Bones. Becauſe the Muſcles and Bones being ſimilar to their Fibres, as is highly [188] probable, and theſe being bigger, and conſequently ſtronger, ſo muſt thoſe be; and on the contrary. 4. Soft, yielding, pappy Fleſh, is a ſure Symptom of looſe Fibres; whereas hard, firm and unyielding Muſcles, are the conſtant Sign of firm Fibres. 5. A white, fair, blanch'd or aſhen-coloured Complexion or Skin, conſtantly indicates a weaker and more relaxed State of Fibres, than a ruddy, freſh, dark ſallow or black Hue; for Reaſons already given. 6. A fat, corpulent and flegmatick Conſtitution, is always attended with looſe, flabby and relaxed Fibres, by their being diſſolved and overſoaked in Moiſture and Humidity. And, on the contrary, thoſe of a dry, clean and firm Make, have ſtrong, firm and tenſe Fibres. 7. Thoſe who are ſubject to Evacuations of any kind, in any Degree greater than what is natural; and thoſe who by any Accident, have ſuffered long by any preternatural Evacuation whatſoever, are, or become of looſe, relaxed Fibres and Nerves. Thus thoſe who frequently run into Purging, or Floods of pale Water, flow at the Mouth or Noſe, or melt into profuſe Sweats, thoſe who any Way have loſt much Blood, have had a Diarrhoea, have recovered of [189] a Fever, and thoſe of the Sex who have purified longer or more than is uſual; all of theſe, are originally, or become accidentally, of weak and relaxed Nerves and Fibres. 8. Laſtly, Thoſe who are of a cold Conſtitution, are apt to run into Coldneſſes on their Extremities, or ready to catch Cold, are alſo of weak and looſe Fibres and Nerves: becauſe theſe are Signs of a ſlow and interrupted Circulation and Perſpiration; which manifeſts a weak Spring in the Fibres of the Coats of the Veſſels, the Fibres of the Muſcles, and a Weakneſs of the Spring of the Scales of the Scarf-ſkin.

§. 5.

On this Occaſion of rehearſing the Signs of weak Nerves, I cannot omit appriſing thoſe of the breeding Part of the Sex, and thoſe who are concerned in them, of their Readineſs of Miſcarrying, unleſs duly tended and managed, eſpecially thoſe of them of tender and weak Nerves, or of too delicate a Conſtitution. The Signs I have now laid down, will always make it evident, if any particular Perſon is ſo or not. And if upon Examination they be found to be ſuch, they will be apt, upon the ſlighteſt Occaſion, to run into frequent [190] Miſcarriages; whereby a great Part of their Poſterity will be deſtroyed, and they themſelves expoſed to Dropſies or Conſumptions, or (which is worſe than either) perpetual Lowneſs of Spirits, Vapours and other Hyſterick Diſorders. And by this Misfortune alone, a conſiderable Part of the better Sort here in England, periſh and are loſt. Nature has formed the Generality of the Sex, of a ſoft, ſlender, and delicate Make. Want of due Exerciſe, a full Table, indiſcreet Nurſes, overfond Mothers, and Hereditary Sharpneſſes, make them much more ſo. And if by Neglect or Accident, they once begin to miſcarry, every firſt Miſcarriage paves the Way for a ſecond, and a third, and ſo on, till the poor, pretty Creature, has neither Blood nor Spirits, Appetite nor Digeſtion left. For one Miſcarriage weakens the Conſtitution, breaks and tears the nervous Syſtem more, than two mature Births. If ever this is to be ſecured or prevented effectually, 'tis to be done, at leaſt attempted, in the firſt Inſtance, if poſſible, at leaſt as ſoon as may be, before a total Relaxation and Diſſolution of the nervous Syſtem is brought on. The Giddineſs, Romping, and Gadding about of the young Creature [191] herſelf, is often the Cauſe of her Miſcarriage. But oftner the Forwardneſs and Indiſcretion of Surgeons and Midwives, by bleeding on every little threatning Symptom, without conſidering the Conſtitution. Bleeding may do well enough in ſanguine, robuſt, and plethorick Conſtitutions: But 'tis Death and certain Rain to thoſe of ſlender and weak Nerves, and the ſureſt Way to cauſe the Miſcarriage 'tis deſigned to prevent, by relaxing the Nervous Fibres; which Bleeding does as certainly, as it leſſens the Quantity of the Blood. The moſt effectual Method I have ever found to prevent ſuch Misfortunes, is, To order thoſe in ſuch Circumſtances, to drink plentifully Briſtol Water, with a very little red Wine, for their conſtant Drink; to lay the Plaiſter ad Herniam, with Oil of Cinnamon, and London Laudanum, in a due Proportion, to their Reins; to keep them to a low, light, eaſily digeſted Diet, eſpecially of the farinaceous Vegetables, and milk Meats; to ſtrengthen their Bowels, with Diaſcordium and toaſted Rhubarb, if they become too ſlippery; to air them once or twice a Day, in a Coach or Chair, and to keep them cheerful, and in good Humour, as much as [192] may be. This Method will ſcarce ever fail, unleſs a latent Scrofula, or ſome other Hereditary Sharpneſſes in their Juices, deſtroy the Birth.

§. 6.

The Tender, Sickly, and thoſe of weak Nerves, ought to have a Regard in the Conduct of their Health, to the different Seaſons of the Year. I have elſewhere* obſerved, that ſuch Conſtitutions begin to ſink, droop and languiſh, about Chriſtmas or Mid-winter, go on from worſe to worſe till the Spring is over, get up a little, as the Sun grows higher and ſtronger, arrive at their Meridian Altitude of Health and Strength about Midſummer, and hold it out ſo long as the Sun warms them, or the Strength they have acquired laſts. Thoſe who have very weak Nerves, fail ſooner, even about the Autamnal Equinox: But they get up ſooner, becauſe their weaker Nerves make leſs Reſiſtance. The Sun new ferments, rarifies, and exalts their viſcid Juices: So that the Circulation is better performed, more full, free and univerſal. The Perſpiration is alſo thereby much increaſed and promoted: [193] And the Load being drawn off, by the Force of the Sun's Heat; their Appetite is ſharpen'd, and their Digeſtion mended: To which the ſerene, warm and clear Air, and the greater Liberty of Exerciſe and Buſineſs contributes. I ſhould adviſe ſuch therefore, religiouſly to follow the Indications of Nature, and to take theſe Benefits it offers then, as a certain Sign of their being beſt and fitteſt for them. After Chriſtmas, and in the Beginning of the Spring, Milk, Eggs, and Spring-Herbs, as Aſparagus, Spinach, and Sprouts come in firſt: Of which I adviſe them, to make the greateſt Part of their Diet then. As the Spring advances, Lamb and Veal, Green Peaſe and Sallading abound. After the vernal Equinox, Chicken and Rabbit, young Turkies, and early Fruit come in Seaſon. About Midſummer, Mutton and Partridge, Colliflower and Artichoak may be had. And Autumn brings in Beef and Veniſon, Turnip and Carrot. And it will be found, the concoctive Powers of weak Perſons, and thoſe of relaxed Nerves, riſe and fortify gradually, as theſe ſtronger Foods come in Seaſon. By Seaſon, I mean not, thoſe earlier Days, that Luxury in the [194] Buyers, and Avarice in the Sellers about London, have forced the ſeveral kinds of Vegetables, and Animals in. But by Seaſon I mean, that Time of the Year, in which by Nature, common Culture, and the mere Operation of the Sun and Climate, they are in moſt Plenty and Perfection in this Country. But the principal Point I would urge is, That ſuch Perſons, would regularly begin to correſpond with Nature, in both leſſening the Quantity, and lowering the Quality of their Food, as the Seaſons indicate, and Providence provides the proper Food in greateſt Plenty and Perfection. By which they will preſerve the Ballance of their Health pretty near equal all the Year round, have the lighteſt and leaſt Food, when their concoctive Powers are leaſt, and their nervous Fibres weakeſt, and riſe in the Food, in proportion as theſe riſe. Add to theſe, That as Winter is beſt for Home Exerciſes, Summer is fitteſt for thoſe without Doors. And as the Day lengthens, their Labour and Exerciſes abroad ought to be lengthened out. Neither Sydenham nor Fuller, have been able to tell the Half of what obſtinate [195] Exerciſe will do, in low, cachectick, conſumptive Caſes.

§. 7.

The Germans have a Proverb, That wiſe Men ought to put on their Winter Cloaths early in Autumn, and put them off late in the Spring. By which they would inſinuate, that People ought always to go well-cloathed. Whatever may be in this, as to Perſons that drink hard, and require a plentiful Diſcharge by the Skin, thoſe who are ſober, or who would render themſelves hardy, ought to accuſtom themſelves to as few Cloaths, both in Summer and Winter, as is poſſible. Beſides the general Rule, of having as few Neceſſaries as may be; much and heavy Cloaths, attract and draw too much by Perſpiration; as Dr. Keill proves, in his Med. Static. Britann. tender and debilitate the Habit, and weaken the Strength. The Cuſtom of wearing Flanel, is almoſt as bad as a Diabetes. Nothing [196] can enfeeble and drain, weak and tender Perſons more. To make this clear, we muſt diſtinguiſh between Perſpiration and Sweating; which differ as widely, as the daily natural Emptying our Bowels, and a Looſeneſs or Diarrhaea. And as no Body in their Senſes, much leſs the Tender and Weakly, would endeavour to encourage this laſt; no more ought they that other of Sweating. For as promoting ſlippery Bowels, would always keep the Fibres of the alimentary Paſſages relaxed; ſo would perpetual Sweating, thoſe of the Skin. And as the Moiſture and Damps that Flanel perpetually keeps the Skin in, and its growing ſo readily dirty, ſhews what a Flux of Perſpiration it promotes there; ſo the perpetual Friction produced by it, gives the Reaſon. If one lays on a ſuperfluous Load of ſtrong Liquors, 'tis happy for him Nature diſcharges the Ocean any how; for he had better ſweat, than burn in a Fever. But for temperate, tender and ſickly Perſons, the more firm and tight all the Organs of their Evacuations be (if they be not totally obſtructed) the better it will be for them, the more it will ſtrengthen their Nerves, and harden their Conſtitution. [197] Nothing but Superfluity in Food or ſtrong Liquors, requires Sweating: And that is the Reaſon, the Germans run ſo much upon it. So far, that * Tſchirnhaus, a very learned and ingenious Gentleman otherwiſe, reſolves the Cure of almoſt all Diſtempers into Sweating, upon obſerving its Succeſs in their Bottle-Fevers. They drink much thin ſharp Wine, which paſſes every way; and when it comes through the Skin, both the Conflict and the Danger is over. But for thoſe Inhabitants of our Iſlands, who are ſober becauſe they are tender, or would preſerve their Health; the lighter and fewer their Cloaths are, both by Night and by Day, in Summer and Winter, the hardier they will grow. The more open the whole Body is to the Air, provided it be benign; the more fluid, and the more active, will the Animal Juices be; and, by conſequence, the more full, and free will the Perſpiration be. For right tempered Air, is beneficial and medicinal to the Animal Juices: And a great Heap of Cloaths, only condenſes our own excrementitious [198] Atmoſphere about us, and ſtops the kindly Influence of this beneficial Element. As to catching Cold, he that lives ſoberly, and avoids nitrous, that is, moiſt or froſty Air, will either not readily catch Cold, or if he does, will ſoon get rid of it. It is only Air thus conditioned, that thickens and coagulates our Juices, and gives painful and dangerous Colds. It is inward Heat only, which deſtroys us. No ſober Perſons ever ſuffered by Cold, unleſs it were extreme, or that they expoſe themſelves obſtinately to it, againſt Senſe and Reaſon.

§. 8.

Another Mean of Health, to the Tender, Studious and Sedentary, is much and often ſhaving Head and Face, and waſhing, ſcraping and paring their Feet and Toes. The great Benefit (beſides the Pleaſure) to the Head, Eyes and Ears, by often ſhaving the Head and Face, and waſhing them Daily in cold Water, with a few Drops of the Compound Spirit of Lavender, or Hungary Water, is beſt underſtood by thoſe that have felt it. The Cutting off the Hair, and ſhaving the Head, will, in the firſt Inſtance, ſcarce fail to cure a Head-ach, a Fluxion, or even a nervous Weakneſs of the Eyes. [199] Any one Evacuation, will not only leſſen the whole Maſs; but, if encouraged, will make that Evacuation more ample and full. The more and oftner the Hair is ſhaved, the faſter and thicker it will grow. So that thus ſhaving the Head and Face frequently, will be like an Iſſue, or perpetual Bliſter on theſe Parts. Beſides the Waſhing with warm Water and Soap, and ſcraping the Skin with a Razor, will cleanſe the Mouths of the Perſpiratory Ducts, from that Morphew and Scurf that adheres to them, and will extremely encourage the Perſpiration from theſe Parts, and give a full and free Vent, to the Fumes on the Head and Brain. And waſhing well, and dipping in cold Water afterwards, will ſhut the Scales of the Scarf-skin, and ſecure againſt catching Cold in the Head, which is frequently a heavy Grievance, to tender, ſtudious and ſedentary Perſons. Therefore I ſhould adviſe ſuch, to ſhave both Head and Face every Day, or every other Day, or as often as they poſſibly can, and waſh them well in cold Water afterwards. What ſhaving does to the upper Parts, the ſame do waſhing and ſcraping the Feet, and paring their Nails to the lower. We know by the Tickliſhneſs [200] of the Soles, what a multitude of fine nervous Fibres terminate in them. Walking, Standing and Treading, render them callous, and the Skin thick and hard; which much injures the Perſpiration, and hinders the Derivation of the Blood and Spirits into them. And 'tis a common Obſervation, That nothing is a ſurer Sign of ſtrong and rank Health, than a kindly Heat, and a profuſe Perſpiration on the Feet. It ſhews a full and free Circulation in the ſmall Veſſels, at the greateſt Diſtance from the Source of Heat and Motion; than which nothing can more plainly indicate great and good Health. On the contrary, weak and tender Perſons, are always cold in the Legs and Feet, and firſt of all feel Cold there in froſty Weather. Let the Tender therefore, and the Weakly, duly once a Week, waſh in warm Water, rub, ſcrape and pare their Feet and Nails. Which will likewiſe prevent Corns, Hardneſſes, and the unnatural Tendency of their Nails into the Fleſh. Theſe are, 'tis true, but low and ſeemingly trifling Obſervations towards Health; but 'tis in this Caſe, as 'tis in a more momentous one; He that deſpiſeth little Things, ſhall periſh by little and little.

§. 9.

[201]

Thoſe tender and valetadinary People, whoſe Studies or Profeſſion oblige them to read or write much, ought, as far as they poſſibly can, to ſtand in an erect Poſture, bending their Head and Breaſt as little as may be, leaning only on a ſloping Desk, and continuing their Exerciſes in that Poſture, 'till they grow weary; then reſt, and be at it again. Cuſtom and Practice, obſtinately perſiſted in, will at length render the Poſture eaſy to them. And 'tis inconceivable, how many and great Advantages it will bring to the Conſtitution. Sitting, Bending and Leaning low, compreſs ſome, if not many of the Veſſels of the Body; and ſo ſtop and retard the Circulation of the Blood and Juices thro' them; which makes a more ready Flux through the other more patent and pervious ones. Whence that Sleepineſs and Diſability to Motion in the Limbs, till the Blood and Spirits, by a proper Poſture, get a free Admittance into them. From this alſo, there enſues an unequable and ſubſultory Circulation of the Juices, and an unequable Secretion in the Glands; and, conſequently, an unequal Growth, Strength and Vigour, [202] of the Organs and Parts. Which is the Cauſe of Rickets in Children; careleſs Nurſes, neglecting to rock, dandle and toſs them ſufficiently, that the Circulation of the Juices and Spirits may be equally promoted every where. And to avoid this Inconveniency, ſeems to be the Reaſon why the Romans and the Eaſtern Nations, lay along, at their great Meals and Feaſts, and when they were obliged to continue long in one Poſture. Beſides, that in Writing or Reading, if one ſits, there is a conſtant Preſſure on the Cavity of the Breaſt and Stomach, which muſt neceſſarily weaken their Functions; and theſe are commonly the Organs, which firſt decay in Clerks and Under Secretaries. And hanging down the Head, is the ready Way to raiſe Fumes and Vapours to it: Whereby ſuch will be expoſed to Lowneſs of Spirits, and perhaps Conſumptions; all which are, in a great meaſure, avoided by an erect Poſture: For thereby all the Organs will be in their natural Situation. Many of the Muſcles will be in Action, and ſo preſs on the Blood Veſſels, to facilitate the Circulation. But chieſly, by this erect Poſture, the Juices will have the Advantage of their own Gavity, to [203] deſcend with the greater Velocity, to warm and cheriſh the lower Parts, which are remoteſt from the Source of Motion; and the groſſer Evacuations will be more readily promoted, and thereby preſerve the upper Regions clear and ſerene: Which will bring great Advantages towards Health and Long Life. But this Practice will never become eaſy, unleſs to thoſe who begin young. Thoſe who dictate or conſult, ought to do them ſtanding or walking; which would relieve both Body and Mind.

§. 10.

The Unwieldy, Fat and Overgrown, beſides the Rules already laid down, I adviſe, in particular, as much as is poſſible for them, to abſtain from Drink of all kinds. No one Rule or Condition, ever was contrived, or can be, of ſo great Uſe, to preſerve and lengthen the Lives of ſuch, as an obſtinate and univerſal Aſtinence from all kinds of Liquors. If the Doctrine be true (as 'tis highly probable) that the Maſs of all the Bodies of Vegetables and Animals, is only Pipes and vaſcular Tubes, formed all at once, in their firſt Rudiments and Seeds; then Growth and Increaſe of Bulk, is only filling and plumping up, diluting [204] and unfolding theſe Pipes with Liquors. We know from Kircher's and Dr. Woodward's Experiments, to what Bulk Vegetables will thrive, by mere Element alone. Two Pigs of the ſame Litter, were fed upon an equal Quantity of Milk; only, to one of them, the Milk was mixt with the ſame Quantity of Water. After a Month's feeding, they were both killed, and that which had the Water, was found much larger and fatter than the other. Dropſies (at leaſt Anaſarca's) have been cured by an obſtinate Forbearance of Drink. And Lethargies proceed from the Moiſture of the Brain. And theſe are the two Diſtempers, Unwieldy, Fat and Overgrown Perſons are moſt ſubject to. Therefore, ſuch ought to avoid Drink, as thoſe do, who have the * Hydrophobia, or are bit by a mad Dog. Which they may eaſily bring about, if they feed only on young animal, and moiſt and cool vegetable Food. But whenever I ſpeak of vegetable Food, I mean that which is dreſſed by Fire.

§. 11.

[205]

To the Aged, and thoſe who are paſſing off the Stage of Life, I have only two Things to recommend, if they would make the laſt Hour, as eaſy, indolent and free from Pain as may be. The firſt is, That they would avoid the Injuries of the Weather, as much as ever they can. The Blood of the Aged is ever moſt certainly poor and viſcid. Their Perſpiration little or none at all; and their concoctive Powers weak. And conſequently, they muſt be ſubjected to, and ſuffer by the weakeſt Injuries of the Weather. Therefore I adviſe ſuch, to keep Home, provide warm Rooms and Beds, and good Fires, whenever the Sky lowrs, Winds blow, or the Air is ſharp. Such are not to expect to raiſe, improve, or exalt their Conſtitutions or Health. Freedom from Pain, to prevent the vital Flame's being extinguiſhed by Accidents, and to have it burn as clear, and as long as Nature, at their Age, has deſigned it ſhould, is all they ought to aim at. Exerciſe is only to purge off Superfluities. If theſe therefore, be careful not to exceed, they will want none, nor would it much contribute to their Eaſe. For in old Men the Bones petrify; [206] the Cartilages and Tendons turn into Bones; and the Muſcles and Nerves, into Cartilages and Tendons. And all the Solids loſe their Elaſticity, and turn, in a great meaſure, into that Earth they are going to be diſſolved into. So that the Solids wanting Elaſticity, Exerciſe can do but little to ſhake off the Load. It will therefore be enough for ſuch, to air themſelves when the Sun lights them, and the Summer Breezes can refreſh them. Or, if they would lengthen out their Days, to remove to a warmer Climate, by which they may live as long as the Crow. The ſecond Thing I would adviſe ſuch, is, To leſſen their Diet gradually, as they grow older, before Nature has forced this Diminution upon them. This is a powerful Mean to make their old Age green and indolent, and to preſerve the Remains of their Senſes to the very laſt. By this alone, Cornaro lengthned out his Days, and preſerved his Senſes, in a great meaſure, intire to a hundred Years. He gradually leſſened his Diet ſo far, that, as his Hiſtorian informs us, he came at laſt to live on the Yolk of an Egg three Days. I will not take upon me to adviſe others, [207] in what Meaſure, either of Time or Quantity of Food, they ought to diminiſh. But this, I think, they ought to conſider, That ſince 'tis certain aged Perſons become Children, as to the Weakneſs of their Digeſtions, they ought to diminiſh, as Children increaſe in their Food, from weaker to weaker, and from leſs to leſs. For as their Solids are unelaſtick, their concoctive Powers weak, their Perſpiration little, and the Expences of Living ſcarce any, their Repairs (not to overlay the Spark of Life remaining) ought to leſſen proportionally. And 'tis to the Neglect of this, in aged Perſons, that thoſe Rheums, Catarrhs, Wind and Colicks, Loſs of Memory and Senſes, thoſe Aches and Pains, and all that diſmal and black Train of Miſeries, that wait on Long Life, is moſtly owing. Which, by a diſcreet and timeous leſſening their Diet, might, in a great meaſure, be prevented.

§. 12.

There is no Miſtake more fatal in the Cure of chronical Diſtempers, incident to the Weak and Tender, than the vain and unjuſt Expectation they entertain of a ſudden and quick Cure, or even of a ſenſible Relief. This, with [208] their Inconſtancy, and Impatience of being confined in their Appetites, makes them either throw off all Remedies and Reſtraints in Deſpair, and give themſelves up to an habitual Indulgence in all thoſe Things that brought on or exaſperated the Diſtemper, or run about changing, from Doctor to Doctor, till they end with a Quack, or die under the Hands of a Mountebank, and are fool'd out of their Lives and Money at once. It is ſurprizing that reaſonable Men can imagine, that in any ſmall Time, any poſſible Methods or Medicines ſhould cure, or even ſenſibly relieve a Diſtemper, that perhaps was brought with them into the World, and interwoven with the Principles of their Being, or, at leaſt, may have been Ten or Twenty Years a breeding, by Exceſſes, or an indiſcreet Regimen. I know no fitter Similitude of the Caſe, than the annual Income of an Eſtate juſt ſufficient to keep one in decent Neceſſaries, and due Plenty and Cleanneſs. If one that has ſuch an Eſtate, run out every Year, for Ten or Twenty Years, and then ſet about to retrieve, before he be come to Starving or a Gaol, would we not count him mad, if he ſhould imagine [209] by Retrenching, Management or Saving, even joining to thoſe Day-labour, that a few Months or Years would recover all, and bring his Eſtate to its firſt Condition. No! he muſt labour, abſtain and manage for ſeveral Years; and the Time required, will be always in a Proportion compounded of the Rate of his former Expences, and his preſent Saving. That is, If his Expences were but ſmall, and his Savings great, the Time will be the ſhorter, in reſpect of the Time he continued his overſpending. If he gives over Saving, he muſt at laſt moſt certainly ſtarve or go to Gaol; and if he begins to ſave in due Time, he will certainly retrieve all; but the whole conſiſts in Labour and Saving for a due Time. Exceſſes and an undue Regimen, is running out of one's Health; which, without a proper Remedy, as Labour and Abſtinence, will neceſſarily bring a Man to Diſeaſes or Death. And theſe muſt be continued a Time proportioned to the Greatneſs of the Exceſſes, with regard to the Labour and Abſtinence. Moſt chronical Diſtempers have for their Parents, corrupted Fluids, and broken Solids, as has been ſhewn. A bad State of the Stomach [210] and alimentary Organs, either beget theſe or accompany them. Suppoſe, for Example, the Caſe be a ſcorbutick Habit, ſhewing it ſelf with Blotches and a watry Ichor, or Bumps, with yellow or black Spots on the Skin, a thick, viſcid, rheumatick Blood, an obſtructed Liver, and a conſtant overflowing of the Gall, Oppreſſion of Spirits, want of Appetite and Digeſtion, and thereby a Waſting, Laſſitude, Inquietude, &c. which I have often met with in your Bon Vivants, and your Free-Livers, who have been born healthy, vigorous and lively; I know no way in Nature to relieve and effectually cure this Caſe, but by oftenrepeated, gentle Vomits and Stomach Purges, as the Choler (which certainly degenerates into Flegm, before the Cure be brought about; for Flegm is but Choler more diluted, or the groſſer Part of the Serum only, as Choler is that of the whole arterial Fluid; and when Choler is come to Flegm, the Cure is half carried on, one Part of the Fluids being already purified, and the Liver free and open; As the Choler, I ſay,) and the Flegm riſes and loads the alimentary Paſſages; Bitters, Aromaticks and Steel varied and preſcribed, according [211] to the Strength of the Patient, and one kind as another has loſt its Virtue; Chalybeat and Mineral Waters, conſtant Labour and Exerciſe; a cool, light, ſpare Diet, and conſtant proper Regimen, long and obſtinately perſiſted in. The Patient will often complain, What! Vomits and Bitters, Galloping and Faſting for ever! Vomits only relieve for a few Days, but do not cure: We grow as bad as ever again, and in ſome Months Perſeverance, find ourſelves juſt where we began. New Doctors muſt be had, and they muſt either be caſhier'd if they purſue the ſame Intentions (which, if they be honeſt Men, they muſt do) or elſe muſt write Things that can neither do Good nor Harm, or thoſe which will actually hurt, for their Fees (for there is no Medium) till the miſerable Perſon has run thro' the whole Faculty; and at laſt got into the Charlatan Tribe. It is certain, that when Nature has begun to throw the groſs and viſcid Parts of the Juices on thoſe looſe and ſpungy Glands, it will continue ſo to do, till it has deflegmated the whole Maſs; and every new Vomit will make Room for another; and there is no other Remedy as long as [212] there is any viſcid Humour remaining, nor can the Decline of the Diſeaſe be diſcovered ſo certainly by any Thing, as by the Leſſening of the Quantity excerned, and the Lengthening of the Intervals: As in a Veſſel of Oil and Water incorporated, a ſure Way to ſeparate the Oil from the Water is, to skim it off as it comes to the Top. Now as long as there is any Oil remaining it will ſwim, if you but give it Time to extricate itſelf from the Embraces of the Water, and then you may ſeparate the viſcid Mixture intirely. No great Purpoſe in Life was ever brought about, but by Time and Patience, and by conſtantly purſuing the moſt natural and beſt approved Means that lead towards that End. Nature works not by ſudden Jumps and Starts, but goes on ſteadily, fortement & doucement, and 'tis Nature that is the true Phyſician: Art only removes Obſtacles, checks Violences, and gently ſollicites Nature the Way ſhe tends. This requires Time and Patience. Tempus edax Rerum. It moſt certainly conſumes chronical Diſeaſes, if not fuelled and fed; Nothing elſe can.

§. 13.

[213]

In fine, Providence has been kind and gracious to us beyond all Expreſſion, in furniſhing us with a certain Relief, if not a Remedy, even to our moſt intenſe Pains and extreme Miſeries. When our Patience can hold out no longer, and our Pains are at laſt come to be inſupportable, we have always ready at Hand a Medicine, which is not only a preſent Relief, but, I may ſay, a ſtanding and conſtant Miracle. Thoſe only who have wanted it moſt, and have felt its friendly and kind Help in their Tortures, can beſt tell its wonderful Effects, and the great Goodneſs of Him who has beſtowed it on us. I mean Opium, and its Solution Laudanum, which, when properly preſcribed, and prudently managed, is a moſt certain and ſudden Relief in all exquiſite and intenſe Pain. The Manner of its Operation may be gathered, from the Obſervations I have made in the preceding Treatiſe. Pain conſtricts, criſps up, ſhortens and contracts animal Fibres. It acts like a Wedge in tearing, rending and dividing theſe ſmall Filaments; it does to them in a living Body, what the Points of Salts do to all animal Subſtances, [214] which are to be preſerved for Food, viz. hardens, ſtiffens and contracts them. The Fibres of live Animals being contractile, tonick and ſpringy, when a hard pointed Body enters them (which is the Caſe in all bodily Pain) the Parts by their contractile Nature, fly from, recede, and ſhun, as much as poſſibly they can, the wounding Inſtrument. This appears in the large Gaſh of a Wound, made acroſs the Fibres of a Muſcle; in the continual Bending towards the other Side, when any Part of one is pained; in the Cramps and Convulſions, nay, and ſometimes Fevers, produced by intenſe acute Pain. Pleaſure, on the contrary, relaxes the Fibres by a gentle, ſoft, and bland, or (as the Mathematicians ſpeak) a commenſurate and harmonious Touch. It acts on the Fibres as two uniſon and concordant muſical Inſtruments act on one another, and by ſtroaking, ſoftening and ſmoothing, comes at laſt intirely to relax and unbend them. The Parts of the Fibres run after, follow and purſue, and at laſt break their Union in ſome Degree, to reach ſuch a demulcent Touch. Some Perſons have had the Faculty to [215] allay Pain, by gently ſmoothing the afflicted Part with their Hands; which in ſome Meaſure was true of the Touching Doctor. Soft Oils, and emollient Herbs, with gentle Warmth, by relaxing the criſped Fibres, will allay Pain. Soft Beds and Cloaths, and tepid Baths will relax and weaken the whole Habit. Now ſince Pain ſo certainly criſps up, conſtricts and contracts animal Fibres, and ſince Opiates infallibly, if duly doſed, relieve and eaſe Pain, I can ſee no poſſible Way it can effect that, but by relaxing and unbending theſe Fibres as much, or near as much, as Pain contracts and draws them up. And that this is the real Fact, we may obſerve from many Effects of Opiates. 1. Nothing is ſo powerful, or ſo certain a Diaphoretick as an Opiate. Nothing cauſes ſuch plentiful Sweating, eſpecially if joined with Volatiles, and promoted with plentiful drinking ſmall, warm Liquors. This it can do only by relaxing the Fibres of the Skin and Perſpiratory Glands. 2. Nothing ſo much palls the Appetite, and weakens the firſt Digeſtions, as the frequent Uſe of Opiates; inſomuch, that moſt People, after a liberal Doſe of [216] them, ſeldom fail to reach, and never care for Food for a conſiderable Time after, till their Effects are wrought off; which are the conſtant Symptoms of a relaxed Stomach and Guts. 3. Nothing ſo much promotes the Eruption of the Small-Pox and Meaſles, the Expulſion of the Stone and Foetus, the Monthly, and the After-Birth Purifications of the Sex, as Opiates; inſomuch, that in difficult Births, they are now the only Reſource of the Midwife Phyſicians; and, when joined with Volatiles, will bring on the moſt powerful and vigorous Throws, in the moſt weak and languiſhing Conſtitutions. Theſe Effects they can produce only by relaxing thoſe Fibres Pain has contracted and render'd unelaſtick in ſome meaſure. 4. Nothing quiets and ſtops Cramps, Convulſions and Hyſterick Fits, ſo ſuddenly and certainly as Opiates do. And every one knows theſe ariſe from violent Contractions, and criſping up of the muſcular Fibres. All theſe, and many more ſuch Effects, Opiates produce, by unbending, looſening, and relaxing thoſe Fibres violent and acute Pain had conſtricted and contracted, and by giving a Reſpite and Reprieve from its Tortures, [217] and thereby allowing Nature (the only true Phyſician) to go undiſturbed about its own Work. The Way it ſtops Purging, and cures a Diarrhaea, I take to be by carrying off the ſharp and watry Humours in the Bowels by Perſpiration, which Opium exceedingly promotes; by quieting thoſe Spaſms and Convulſions, and allaying thoſe Stimulations excited by Purging; and ſettling and calming the Violence of the Periſtaltick Motion of the Guts, which hurries off their Contents. I will not take upon me here, to determine the proper Caſes for Opiates, or their Doſes. That is the Buſineſs of the Phyſician. But in general I may ſay, Wherever Pain is acute, intolerable and paſt enduring, where it may indanger Convulſions, a Fever or Inflammation; after premiſing the proper univerſal Evacuations (ſuch as Bleeding, Bliſtering, Cupping, Purging or Gliſtering, as the Caſe requires, or will bear) Opiates then will moſt certainly relieve, and may be ſafely adminiſtred. If the Caſe is attended with Vomiting, ſolid Opium will do beſt; becauſe it will be in a ſmaller Volume, and will not be ſo readily rejected. If ſpeedy Relief be required [218] where there is no Vomiting, then Laudanum will diſperſe ſooneſt through the Habit, becauſe Liquid, and joined with a Spirituous Vehicle will ſooneſt effect the Deſign, raiſe the oppreſſed Spirits more, and penetrate deeper and quicker. In common Caſes a vinous Vehicle will be ſufficient, becauſe Opium is beſt diſſolved in Wine, to make Laudanum. There are four Caſes, in which 'tis abſolutely and eminently neceſſary; the Cholick; the Stone; the hard Labours, After-Birth and Monthly ſluggiſh Purifications of the Sex, eſpecially if attended with violent Pain, as is common in ſuch Caſes; and in the Gout and Rheumatiſm. In the firſt, it ought always to be given with ſome Stomach Purge, as Elixir Salutis, or Tincture of Hiera Picra, with Syrup of Buckthorn, and in thoſe of more tender Bowels, with Tincture of Rhubarb; eſpecially if the Cholick is in the lower Bowels and attended with no Vomiting; in which Caſe an artificial Vomit is to be premiſed, if Circumſtances forbid it not. In the Stone it ought to be given with Oil of ſweet Almonds, or in ſome ſoft Emulſion, to lubricate the Parts. In the two laſt Caſes, it ought always to [219] be given with proper Volatiles, Antihyſtericks and Attenuants. In violent and acute Pain, the firſt Doſe ought to be large, at leaſt from thirty to forty-five Drops of liquid Laudanum, or its Equivalent in Opium, from two Grains and a half, to three and a half; and afterwards to be increaſed by fifteen Drops of Liquid, or half a Grain of ſolid Laudanum every half Hour, till the Pain begin to remit; and then an intire ſtop is to be put to its Adminiſtration. And thus the End will be obtained without any Fear of over-doſing. And the Truth is, there is leſs Hazard of that, than Perſons are aware. For thoſe who die of an Over-doſe of Laudanum in the Opinion of the World, would have lived few Days without it. For there are thoſe that by Cuſtom, have brought themſelves to two Drams of ſolid, that is, near ſix Ounces of liquid Laudanum a Day. And I know a Gentleman who took near three Ounces at once, inſtead of Elixir Salutis, and had never taken any in his Life before; who (though it extreamly weakened his Stomach for ſome Time, and that he doſed almoſt a Month under it) yet did well, and, for ought I know, is alive [220] ſtill, though it be many Years ſince. If the preceding Doſe be rejected by Vomiting, about a Third Part may be ſuppoſed to ſtay; and then the ſubſequent Doſes may be proportioned accordingly. The Difference of Conſtitutions will make no great Alteration here, ſince very weak Perſons ſeldom ſuffer very violent Pain, which is the only Caſe I am here conſidering.

§. 14.

To draw towards a Concluſion. The Grand Secret and Sole Mean of Long Life, is to keep the Blood and Juices in a due State of Thinneſs and Fluidity, whereby they may be able to make thoſe Rounds and Circulations through the animal Fibres, wherein Life and Health conſiſt, with the feweſt Rubs and leaſt Reſiſtance that may be. In ſpite of all we can do, Time and Age will fix and ſtiffen our Solids. Our original Frame and Make renders this unavoidable and neceſſary. As in the greater World, the See Sir Iſaac Newton's Princip.Quantity of the Fluids is Daily leſſening and decreaſing; ſo in our leſſer World after [221] a limited Time, the Appetite and Concoctions failing, the Fluids are leſſened and ſpent on the continual Repairs of the Solids, and thereby loſe their Nature, and become firm and hard. For by inſinuating themſelves into all the Pores of the Solids, and the Interſtices of their Parts, and ſtraitening and damming up the ſmall Veſſels, which carry in Nouriſhment to the internal Subſtance of the Solids, and ſo depriving them of their Moiſture and Lubricating Juices, theſe Solids come at laſt to harden, ſtiffen and fix, and thereby loſe their Elaſticity and Springineſs. Here the Proceſs is Mechanical and Neceſſary. Age and Time, by weakning the Concoctions, impairing the natural Heat, which conſiſts in a brisk and extended Circulation of the Juices, by the turning thoſe Juices into ſolid Subſtances, and thereby fixing and hardning theſe Solids, and depriving them of their due Elaſticity, the Fluids circulate with leſs Velocity and Force, and ſeldom reach the Extremities and ſmalleſt Veſſels, but paſs through the more patent and larger Veſſels, by their biggeſt lateral Branches. And if with all theſe unavoidable and irremediable [222] Circumſtances, both the nutritious and ſerous Part of the Blood, and the globular, become viſcid, thick and glewy, the Circulation muſt ſtop at laſt, and come to an End. Now 'tis certainly in a great meaſure in our Power to maintain the Juices in a due State of Fluidity and Thinneſs, and to render them ſuch, if they are not corrupted to an extreme Degree, ſo that the remaining Part of Life be not too ſhort for ſuch a tedious Work. We certainly may dilute and thin any Fluid, that has an Inlet and Outlet. And the more fluid a circulating Liquor is, that is, the ſmaller and finer its Parts are, the leſs Force it will require to ſet it a going, and to continue its Motion. And in animal Bodies the thinner and more fluid the Juices are, they will not only circulate by the leſs Force, and with leſs Reſiſtance (i. e. Pain) but alſo, they will preſerve by their Circulation, the Solids the longer from ſtiffening and hardening. There is not a more miſchievous, nor greater Miſtake than the common one, that thin Blood is poor Blood, which the Vulgar and Herd of Mankind are as terribly affrighted for, as outward Poverty and Want. [223] For, on the contrary, the thinneſt and moſt fluid Blood is the richeſt, that is, the beſt Blood (if rich and good mean the ſame Thing). For in Hydropical, Anaſarcous, Cachectick, and Scorbutick Perſons, both the ſerous and globular Part of the Blood is thick, glewy and acrimonious, ſo that it can neither get thro' the ſmall Veſſels, nor can it be long contained in them, but corrodes and frets them, and ſo falls (at leaſt the thinneſt Part of it) into the Cavities, and begets a Dropſy; or ſtops in and obſtructs theſe ſmall Veſſels, and ſo becomes an Anaſarca or Scurvy. In all which Caſes, the ſerous Part is overloaded with urinous Salts, and becomes a perfect Lixivium; ſo that by its Groſſneſs it cannot run into Globules, to facilitate the Circulation through the Capillaries (for theſe ſmall elaſtick Globules, by turning Oval or Oblong, wonderfully facilitate the Circulation of the Juices through the ſmall Paſſages) and the red or globular Part becomes a mere Cake of Glue; and thus the Quantity of Serum is increaſed, and the Quantity of the globular Part gradually leſſened. And in this Senſe (of a greater proportion of Serum) this State of the Blood may be [224] called thin; but it can in no Senſe be called good Blood. The thinneſt and moſt fluid Blood, is ever to be look'd upon as the beſt Blood, as conſiſting of fineſt and ſmalleſt Parts, which moſt readily runs into red Globules, and moſt eaſily circulates thro' the capillary Veſſels, which is the moſt ſolid Foundation of good Health and Long Life. Now as nothing but indulging in ſtrong high Foods, which the concoctive Powers cannot break and divide into Parts ſmall enough to run into red Globules, or circulate through the ſmall Veſſels, but overſtock them with urinous Salts, which run into Cluſters, and firſt obſtruct, and afterwards break theſe ſmall Veſſels, and in wallowing in ſtrong Liquors, which parboil and eat out the tender and delicate Fibres of the Solids; I ſay, as nothing but ſuch an Indulgence, and ſuch Exceſſes, long continued and obſtinately perſiſted in, can beget ſuch a State of the Fluids and Solids, and ſo bring on a Cachexy, which may end in a Dropſy, or ſome other fatal chronical Diſtemper, according to the Habits and particular Make and Conſtitution of the Party (for no Perſon that lived low and meagre, and drank [225] only ſmall and thin Liquors, ever became Hydropical, if his Solids were originally firm, and his Fluids not tainted with ſome hereditary Sharpneſs) ſo I know nothing under the Sun, that can ſolidly and fully effectuate the contrary State of the Blood and Juices, to render them thin, ſweet, and in a conſtant flowing Condition, but taking the contrary Meaſures, and keeping to a ſtrict Regimen of a thin, fluid, ſpare and lean Diet. We have no poſſible Way to attenuate, clean and dilute a Veſſel full of groſs, glewy, and foul Mixtures, that has only a ſmall Inlet and Outlet, but by pouring into it a thin, clear, inſipid Fluid, and by ſhaking it often and much. It is much the ſame with an animal Body. No voluptuous nor lazy Perſon, unleſs he has had an original Conſtitution of Braſs, was ever a long Liver. And even then, as his Life has been more Miſery and Pain, than ever a ſober Gally Slave endured, his End, and the latter Part of his Days has been Rack and Torture, Horror and Deſpair. And though he has not had the Hope nor Conſolation of a Martyr, yet his Sufferings have been far more exquiſite and extreme. All thoſe who have lived [226] long and without much Pain, have lived abſtemiouſly, poor and meagre. Cornaro prolonged his Life, and preſerved his Senſes, by almoſt ſtarving in his latter Days; and ſome others have done the like. They have indeed thereby, in ſome meaſure, weakned their natural Strength, and qualified the Fire and Flux of their Spirits: But they have preſerved their Senſes, weakened their Pains, prolonged their Days, and procured themſelves a gentle and quiet Paſſage into another State. Gentle domeſtick Purges frequently repeated, due Exerciſe, and the Uſe of the other Means preſcribed in the foregoing Treatiſe, will mightily contribute toward this End. But the Ground work muſt be laid, carried on, and finiſhed in Abſtemiouſneſs; and though not in abſolute Faſting (for that is no ways required, and would be prejudicial) yet in a thin, poor, low, light and meagre Diet. All the reſt will be inſufficient without this. And this alone, without theſe, will ſuffice to carry on Life, as long as by its natural Frame it was made to laſt, and will make the Paſſage eaſy and calm, as a Taper goes out for want of Fuel.

Miſcellany RULES of Health and Long Life.

[227]
  • 1. CHRONICAL Diſeaſes laſt long, wear out the Conſtitution leiſurely, and are accompained with a ſlow Pulſe; whereas acute ones ſoon terminate either in Death or Recovery, and are joined with a quick Pulſe.
  • 2. The Scurvy is the Root of moſt chronical Diſeaſes of the Britiſh Nation; and is a neceſſary Conſequence of their Way of living almoſt wholly on animal Food, and drinking ſo much ſtrong Liquors.
  • 3. Soft, thin, ſmall, ſhort, fair Hair, ſlender Muſcles and Bones; ſoft Fleſh; a white, fair, blanch'd or aſhen-colcured Complexion; a fair, corpulent, flegmatick, cold Conſtitution; Chillineſs, eſpecially in the Feet; a Readineſs to catch Colds; and being ſubject to immoderate Evacuations of any kind, are certain Signs of looſe, flabby, or relaxed Nerves.
  • [228]4. Women of weak Nerves are very ſubject to Miſcarriages. Their Danger is increaſed by high Living, and indiſcreet Bleeding. The only Remedy for them, is drinking Briſtol Water and red Wine, with a low and light Diet, going Abroad to get Air, and uſing Aſtringent Plaiſters, and other proper Medicines to corroborate their Bowels.
  • 5. The Weak and Sickly (as their Concoctive Powers fail in Winter, and recover in Summer) ſhould carefully proportion the Quantity and Quality of their Food, to the Strength of them in the ſeveral Seaſons.
  • 6. The fewer Cloaths one uſes, the hardier he will be. Flannel and great Loads of Cloaths by Day or Night, relax the Fibres, and promote only Sweating, inſtead of the natural and beneficial Perſpiration.
  • 7. The Weak, Sedentary and Studious, ſhould frequently ſhave their Head and Face, waſh and ſcrape their Feet, and pare the Nails of their Toes.
  • [229]8. People that read and write much, ought to do them ſtanding, or in as erect a Poſture as they can. And thoſe who can go about any Part of their Studies walking, ſhould do it.
  • 9. The Fat, unweildy and over-grown, ought to avoid all manner of Drink, ſtrong and ſmall, and even Water itſelf, as much as poſſible. And if their Food be Vegetables and young Animals, they will have little Occaſion for any Liquor.
  • 10. The Aged ſhould (1) carefully guard againſt all the Injuries of the Weather; and (2) leſſen the Quantity, and lower the Quality of their Food gradually, as they grow older; even before a manifeſt Decay of Appetite force them to it.
  • 11. As chronical Diſeaſes are not brought on all at once; ſo they cannot be quickly removed. A gradual Corruption, muſt be gradually remedied. 'Tis contrary to the Nature of chronical Diſeaſes to be quickly cured.
  • [230]12. In all acute and vehement Pain, Opium is the ſovereign Relief, particularly in the Colick, Stone, Gout, Rheumatiſm, and hard Labour of Women. It operates by relaxing and unbending the Fibres, overſtretched and criſped up by Pain.
  • 13. The great Secret of Health and Long Life, lies in keeping the Blood (and conſequently the other Juices of the Body) in a due Degree of Fluidity.

CONCLUSION.

TO Conclude, without taking the Benefit of Revelation, which, in a Senſe relating even to our mortal Bodies, has brought Life and Immortality to Light; if but the Precepts of the Pagan Philoſophers were obſerved,

—Servare Modum, Finemque tueri,
Naturamque ſequi.—

[231]If Men would but obſerve the golden Mean in all their Paſſions, Appetites and Deſires; if in all their Thoughts, Words and Actions, they would but mind, I will not ſay the End of their Being and Exiſtence here, but the End to which their Thoughts, Words and Actions naturally tended in their laſt Reſort; And, Laſtly, If in the Gratifications of their Appetites, Paſſions and Deſires, they follow'd the uncorrupted Dictates of Nature, and neither ſpurred her on beyond her Craving, nor too violently reſtrained her in her innocent Biaſs; they would enjoy a greater Meaſure of Health than they do; have their Senſations more delicate, and their Pleaſures more exquiſite; live with leſs Pain, and die with leſs Horror. For had it not been for the Lewdneſs, Luxury, and intemperate Gratifications of the Paſſions and Appetites, which firſt ruined and ſpoiled the Conſtitution of the Fathers, whereby they could communicate only a diſeaſed, craſy and untuneable Carcaſs to their Sons, ſo that with the World's Decay, vicious Souls and putrified Bodies, have in this our Age, arrived to their higheſt and moſt exalted Degrees; I ſay, Had it not been for theſe Evils, there never had [232] happened ſo much Sickneſs, Pain and Miſery, ſo unhappy Lives, and ſuch wretched Ends, as we now behold among Men. But even in this our lapſed Eſtate and Condition, had the Dictates of Nature and Reaſon, not to ſay Religion, been followed; we might have paſſed our Days in Indolence (at leaſt from chronical Diſtempers) if not innocent Pleaſures, arrived at a good old Age, with our Senſes free, and our rational Faculties clear, and at laſt departed in Peace, as a Lamp goes out for Want of Oil. And let the Gentlemen of Wit and Fire, of Banter and Sneer, hug themſelves ever ſo much in their boaſted Tranquillity and Security, gratify their Paſſions, Appetites and Humours to the Full, and deſpiſe Futurity and Whining; I dare promiſe, when the Farce is ended, and the laſt Minutes are drawing on, they would prefer a Life thus led, and an End ſo calm, to all the Pleaſures of Lewdneſs and Senſuality, and the Bounces of a falſe and ignorant Security.
