THE PREFACE.

[]

THOUGH Walton Water, is here held out, as poſſeſſing the ſame Properties and Medicinal Powers as Cheltenham Water, it is not done with the moſt diſtant View, to leſſen the Reputation of that Water, and the Reſort to Cheltenham. On the contrary, it is preſumed, it will be a Satisfaction to Invalids to be aſſured of having within a ſmall Diſtance, a Water of the ſame Kind, to which recourſe may be had, when the Numbers are ſo great at Cheltenham, as to be inſufficiently ſupplied from the Well there.

In this point of View, the Water near Tewkeſbury muſt be uſeful to Cheltenham in full Seaſons, and, cannot injure it in any one, at its priority in uſe, and, the habit of Reſort for Amuſement, as well as Health, will give Cheltenham the Preference.

Tewkeſbury, however, has equally a Right to the Benefit of its natural Riches, and to the Advantages which may accrue to it from the Vicinity of Walton Waters in particular. This Borough is ſituated on a fertile Plain, at the Conflux of the River Avon with the Severn. The Town is well built, and now well paved, and, Proviſions of every Kind, particularly the fineſt Salmon, are in great [iv]plenty. It communicates by a very good Road, to fine rides towards Worceſter, Upton, and Malvern, and is only nine Miles from Cheltenham.

In theſe rides, the various Views of a moſt Pictureſque Country, charm the Eye, and make the ſalutary Exerciſe of riding delightful. Malvern, riſing in b [...]nign, Majeſty, diffuſes all around a pure and temperate Air; a Water exceeding all others in elementary Purity; which every Year manifeſts its ſalubrity in curing Diſeaſes which have baſſied the Power of Medicine in other Situations.

Tewkeſbury, and its Environs, beſides the ſtriking beauties of the Country, preſent to the Obſervation of the curious; A Field of Battle where Victory fixed the Crown on the Head of Edward IV. A Church, one of the fineſt Gothick Structures in England; in which lie the Remains of Edward Prince of Wales, Son of Henry VI. cruelly murdered in cold Blood, with the Duke of Somerſet and many other Noblemen and Gentlemen who ſhared his Fate after that deciſive Battle.

My Motto, is proper in more Senſes than one; for taking advantage of the Epiſtolary Form; I have attempted to illuſtrate the Uſe of the Lymphatic Glands, acknowledged to be hitherto undiſcovered, as well as to make known the Properties of a new Medicinal Water.

SOME FARTHER EXPERIMENTS On WALTON WATER, Made in NOVEMBER, 1787, By JOHN JOHNSTONE, B. A. Of MERTON COLLEGE, OXFORD.

THE Water, on which the following Experiments were tried, had been drawn from the Spring ſeveral weeks before it was uſed. And though it was conveyed from Walton to Birmingham in Bottle [...] well corked and covered with Wax, yet the appearances which reſult from the preſence of the Volatile Ingredients are not to be expected in theſe Experiments.

1. THIS Water did not immediately become Purple with Tincture of Galls, but by ſtanding it contracted a duſky greeniſh colour with a variegate Pellicle at the top.

[11]

2. PHLOGISTICATED Alkali did not occaſion any change of the colour in the Water.

THE fixed Air having eſcaped, the Iron was precipitated, and of courſe could not exhibit thoſe Appearances which it did in the Experiments made by my Father at the Spring.

3. SYRUP of Violets made it of a light green Colour, Tincture of Turnſole became brown when mixed with it. Tincture of Brazil Wood gave it a blue caſt.

THE Appearances produced by theſe three Precipitants were occaſioned either by Magneſia or Alkali, diſengaged by the eſcape of the fixed Air.

4. ACID of Sugar diſcovered Lime, by precipitating it in the form of a white Powder.

5. SALITED Terra Ponderoſa, by attracting the Vitriolic Acid, occaſioned a white turbidneſs in this Water.

6. NITRATED Silver ſhewed the preſence of Marine Acid; its attraction for it producing a white Cloud, which on ſtanding, became of a black colour.

7. AN Alkali, very copiouſly precipitated a white Powder, which appeared to be Magneſia.

BY ſeveral Experiments, a quart of the Walton Water yielded, on Evaporation, 120½ grains.

I. THE reſidue of a Quart of this Water, was firſt [12]mixed with Alcohol, which took up 6 ½ grains of it. This, by its deliqueſcing in the air, was found to conſiſt of Magneſia.

II. Diſtilled Water diſſolved 105 grains of it. As I could not cryſtalliſe the whole, I cannot tell the proportion of each Salt, but I had reaſon, both from what did cryſtalliſe, and from Experiment, to ſuppoſe, that Vitriolated Magneſia is the moſt abundant in this Water. A quantity of Alcohol, ſufficient to precipitate the Baſes of thoſe Salts in which there was Vitriolic Acid, was mixed with a pint of Walton Water. A copious Precipitation enſued, which on examination proved to be Magneſia alone. For on adding Syrup of Violets to the Magneſia in diſtilled Water, no evidence of Alkali appeared more than what Magneſia would alone have given.

To a quart of Walton Water was added a quantity of Vegetable Alkali ſufficient to precipitate all the Magneſia. When the Precipitation was over, the whole was ſiltered, and the Water ſet to cryſtalliſe. The Cryſtals in general, were thoſe of Vitriolated Tartar, and a few reſembling thoſe of Glauber's Salts appeared. A very ſmall quantity remained uncryſtalliſed, which perhaps, was common Salt.

III. DISTILLED Vinegar was mixed with what the Water left, and took up 5 ½ grains of it. On Examination this proved to be Lime. It had a remarkable pungent taſte, did not deliqueſce in the Air, and formed on the Addition of Vitriolic Acid, a kind of Gypſum.

[13]

IV. AN Alkali diminiſhed the remainder 1 ½ grain. I could not exactly tell what the Alkali took up here, but it ſeemed to be a kind of Argillaccous Earth.

V. THE Alkali left nearly 1 ½ grain of a black looking Earth. This was mixed with diluted Marine Acid, which diſſolved nearly the whole of it. Phlogiſticated Alkali, dropped into the Solution, immediately produced a very bright blue Colour. I therefore concluded that the grain and very ſmall quantity more which the Marine Acid had diſſolved was Iron. The ſmall quantity of Earth which did not diſſolve in the Acid, as it reſiſted all the above mixtures, I concluded to be Siliceous Earth.

THERE appears then to be in a Quart of Walton Water,

 Grains,
I. OF Aerated Magneſia,6 ½
II. OF different Salts, but chiefly Epſom,105
III. OF Aerated Lime,5 ½
IV. OF Earth, perhaps Argillaceous1 ½
V. OF Aerated Iron, with a little Siliceous Earth1 ½

CHELTENHAM Water (of which I had a few Bottles) exhibited the ſame appearances with Precipitants, only in ſome inſtances they were more ſtriking.

A QUART of Cheltenham Water yielded, on Evaporation, 127 grains. I tried the Experiments with Alcohol and Vegetable Alkali, on Cheltenham, with the ſame Appearances as with Walton Water, only a large Cryſtal of Glauber's Salt appeared in the Veſſel with the Alcohol.

EXPERIMENT 1.

[14]

SHEWS Walton Water abounds with fixed Air. Lime becomes quick, calcined or cauſtic, by the expulſion of this Air by fire; and being attracted again from this Water, the Calcareous Matter before held in Solution, becomes mild and precipitates in form of a clear and white powder. The immediate precipitation, which takes place by the mixture of Walton Water with Lime Water, and ſtill more clearly the Air forced from Walton Water agitated with Lime Water, is therefore a certain teſt of the preſence of fixed Air in Walton Water.

2. BY this experiment, Iron in a ſmall quantity, appears to be one of the ſugitive ingredients in the Walton Water. This, as well as ſome abſorbent earth, is kept in a diſſolved ſtate by the fixed Air and the Sulphureous Gas contained in it: When the fixed Air flies off, which it does much ſooner than the Hepatic Gas, the Iron precipitates, and the Water is no longer capable of becoming Purple by aſtringents. The action of heat carries off the Hepatic Gas, which appears to hold the abſorbent earths in Solution, which are left by evaporation; and to which the ſoft, almoſt oleaginous taſte, with which this Water ſtrikes the tongue, is probably owing.

[15]

3. THE addition of Saccharum Saturni diſcovers the preſence of the Hepatic Air, another fugitive principle contained in this Water, as well as that of Cheltenham: But it is much leſs fugitive than fixed Air, being often perceived, both in the Cheltenham and Walton Waters, after they have been bottled a conſiderable time. This Sulphureous or Hepatic Air, found in this and in other Waters, has been the occaſion of much controverſy among the Gentlemen who have analyſed Waters: Mr. Kirwan, has, probably finally, ſettled the diſpute, by ſhewing that Hepatic Air is no other, than actual Sulphur kept in Solution, in an acrial State, by union with the matter of heat, Ph. Tr.

4. IT is evident, from this article, that the fixed Air only diſſolves and keeps Iron ſuſpended in the Water. Its diſappearance ſo ſoon, ſhews its very volatile Nature, and, the neceſſity of reſorting to theſe Springs, to have the benefit of a principle and ingredient, which gives penetrability, and action to the Saline contents of the Waters.

5, 6. SHEW the Salts contained in theſe Waters are neutral: And, that neither the acid nor the Alkali, of which they are compounded, prevail.

7-11. DEMONSTRATE, that Vitriolated magneſia, is the principal Salt contained in the Walton Water. The attraction of an alkaline Salt, and eſpecially that of the cauſtic Alkali, with the Vitriolic Acid, is greater than that of the Magneſia, which is precipitated in theſe experiments.

[16]

8. THE exiſtence of Sea Salt, is manifeſted by this experiment, and by the cubic Cryſtals formed in the reſiduum.

9, 10. FROM all our experiments, fixed Air diſſolving a ſmall quantity of Iron: Hepatic Air, united with an abſorbent earth, appear to be the fugitive ingredients of the Walton Water. The fixed ingredients diſcovered by evaporation and cryſtalliſation, appear to be a Vitriolated Magneſia, united with a little Vitriolated Mineral Alkali, in the quantity of ſix or ſeven drachms, in one Gallon of Water. Magneſia, Lime and abſorbent earth, and a deliqueſcent bitter Lixivium, conſiſting of ſalited Magneſia and Lime, with a few grains of entire Sea Salt, altogether, about a drachm or two to a Gallon.

THAT theſe alſo are the component Medicinal ingredients in the Cheltenham Water, appears by the analyſis, of the learned Dr. Fothergill, of Bath.

THIS Gentleman, in his very valuable experimental enquiry into the nature and qualities of Cheltenham Water, p. 42. concludes, "from the preceeding experiments, a Gallon of the Water, wine meaſure, appears to contain the ſubſequent principles, nearly in the following proportions: Native Glauber Salt, with a portion of Epſom Salt, one ounce; Sea Salt, five grains; Iron combined with fixed Air, five grains; Magneſia combined with fixed Air, twenty five grains; Calcareous earth, or Selenite, forty grains; fixed Air, combined with phlogiſticated [17]Air, twenty-four ounce meaſures. To theſe may, perhaps, be added a ſmall proportion of Hepatic Gas or Hepar Sulphuris converted into Vapour by the ſeparation of its phlogiſton."(a)

BY this ingenious Work, it appears, and is ſufficiently known to all who frequent Cheltenham, that the Iron is very ſoon precipitated from the Water, after it is drawn from the Pump; and, in a ſhort time it cannot be made to aſſume a purple colour, by the addition of aſtringents.

THE Salts of the Walton and Cheltenham Waters, are both ſoluble in a very ſmall quantity of Water, equal to their weight nearly: And their impreſſion on the human ſenſes, and, their action in the bowels, is the ſame.

IN ſo many points, the Cheltenham and Walton Mineral Waters, are entirely like each other; a pint or leſs of each opens the body; ſome find a ſmall addition of the Walton, neceſſary to produce the ſame effect in the ſame degree; others find no difference; the purgative Salt is ſomewhat leſs, about a drachm in a gallon, in my experiments; but the quantity of fixed Air, and Steel are at leaſt equal. The Hepatic Air ſeems to prevail in the Walton Water, over the Cheltenham, which gives it a moſt pleaſing almoſt Oleaginous ſoftneſs, and makes it highly grateful in taſte, and gentle in operation, and, [18]far more ſuitable in diſeaſes of the kidneys, and urinary paſſages, than the Cheltenham Water itſelf.

WITHOUT, therefore entering into a farther detail of Chymical reſearch, I apprehend the ſimilarity of the Walton, to the Cheltenham Water, to be ſufficiently aſcertained, to warrant its uſe and application in the diſeaſes, for which Cheltenham Waters have been uſed with advantage.

THE analyſis of Mineral Waters, undoubtedly is highly uſeful; but notwithſtanding the perfection to which it is carried by diſcoveries in modern Chymiſtry, I apprehend it gives a very imperfect idea of the real compoſition of Waters; in ſhort, ſuch an idea as diffection gives of an animated body, a view of its parts disjointed, and ſeparate, very different from that union, on which ſymmetry and life depend.

IT is on this account, that the exhibition of the ingredients found to compoſe mineral Waters, and the imitations of many of them, adminiſtred as Medicines, fall ſhort of the Waters prepared by Nature, eſpecially when drank at the ſources.

IT is the ſame in other parts of the Materia Medica: An analyſis, in ſome meaſure, aſſiſts in accounting for the operation of a Medicine, but ſeldom enables us to prepare, and compound to perfection, the natural productions we pretend to imitate.(b)

[19]

THE uſe, and advantage of Waters, is eſtabliſhed by experience alone, as well as that of every article in the Materia Medica. The advantages found from the uſe of the Walton Well, in various eruptive diſeaſes, and in old ſordid ulcers, as well as in many other diſeaſes, has already been ſo conſiderable as to confirm the expectation grounded on their being ſimilar to the Cheltenham Water.

IT will undoubtedly be found as much like Cheltenham Water, as that Water is like itſelf at different ſeaſons. Seaſons occaſion accidental differences of ſaturation in all Mineral Waters, the cauſe of which, is ſometimes known, and ſometimes unknown. Rainy ſeaſons, while they make Springs more abundant, render the Mineral impregnation at the ſame time weaker. To this alteration, the Walton Water muſt be ſometimes liable, as it lies on a plain, part of which is frequently overflowed with Water. But, if by experience, this ſhall be ſound to have any conſiderable influence, means will be uſed to remove the inconvenience. An inconvenience which is very ſeldom likely to happen in dry and warm ſeaſons, in which, Waters of this claſs, are for the moſt part reſorted to.

AFTER all, I am perſuaded, that the dilution of Mineral Waters is very ſeldom any injury to the patient. The virtues and powers of Mineral Water, depending principally on the quantity of Water, the medium, in which the Medicinal ingredients are [20]ſuſpended; the vehicle which conveys them into the ſmalleſt veſſels, and makes them capable of removing obſtructions fixed in them, and in various glands; hence the ſame Medicinal ingredients, given in the uſual forms, have but little efficacy in removing ſuch diſeaſes.

THE healing powers of the Walton Well, and thoſe of its Siſter of Cheltenham, are owing to the mixture of a neutral compound of vitriolated Magneſia, commonly called Epſom. or Cathartic Salt; to vitriolated Mineral Alkali, or Glauber Salt, with a ſmall portion of ſalited Mineral Alkali, Magneſia, and Lime, nearly to the quantity of a drachm, in a pint of Water; alſo to a conſiderable quantity of fixed Air, and Hepatic Gas, by the former of which Iron, and by the latter Magneſia, and abſorbent Earth, are held in Solution.

THE whole is a compoſition, friendly to appetite and digeſtion; as well as ſoft, and pleaſing to the taſte. It is alſo a penetrating deobſtruent, and, attenuating medicine, and in ſenſible operation, a quick and gentle Laxative and Diuretic; and when applied with diſcretion, it may be continued a long time without any dimunition of ſtrength.

IT is obvious, this Water contains Saline ingredients, and, others poſſeſſing different attractive powers and aſſinities, which, though ballanced in the Water; yet, when mixed with animal fluids, and Salts in the courſe of digeſtion, Chyliſication, [21]and in circulation with the blood, muſt be ſo changed, and varied as to form new attractions, and combinations in their courſe through the veſſels, whence compounds poſſeſſing properties, different from what exiſted before, will be produced, and the ſyſtem itſelf will be changed. It is well known, that cold is generated by diſſolving Salts; and, that while Saline Bodies, of different affinities, and attractive powers, are forming new compounds; ſuch Salts in the proceſs of mutual attraction, and incorporation, produce heat. In this manner, and from ſuch cauſes, new ſtimuli, with other alterations, take place in the glands, and remoter veſſels of our ſyſtem, from the Salts, combined with other ingredients in Mineral Waters; and, it is by theſe means, as well as evacuation, they become beneficial, and are really valuable alterative Medicines.

THE Walton Waters, being a compound, ſui geveris, ſimilar to Cheltenham, they both operate primarily, and principally on the inteſtines, as a gentle purgative, ‘"Their mode of operation, (ſays Dr. Smith, p. 21, 22,) upon the inteſtines, producing an eaſy, ſudden diſcharge, is explainable upon the principle of the tenuity, and uniform diffuſion of the ingredients in the Water. For the Water, after having performed its ſtrengthening, and exhilarating office upon the ſtomach, paſſes quickly into the inteſtines as ſluids do, carrying along with it, more or leſs of all its ingredients, but particularly its great dilution, and conſequent diſperſion [22]all over the internal ſurface of the canal, vellicates the innumerable, little exhalent veſſels, with which that cavity is crouded, into a plentiful ſecretion; and notwithſtanding the ſtimulus may be but ſlight on any particular part, on account of the minuteneſs of the particles of the Salt; yet as they are univerſally diffuſed, and act upon the whole ſyſtem of exhalents at once, a more eopious and expeditious evacuation is produced, than what is often attainable from a much larger quantity of any of the other more ſtimulating purgatives leſs attenuated; attended at the ſame time with theſe important advantages; that as the ſtimulus is gentle, no griping pain is likely to be excited, and as it is ſuperficial, the particles muſt ſoon be waſhed off in the general current, without leaving behind them any of thoſe diſagreeable feelings that uſually hang in the rear of other Cathartics."’ (c)

COROLLARY. Mineral Waters in general, derive their healing powers much leſs from the metals, earths and ſalts, often inconſiderable in quantity, which remain after evaporation, than, from the volatile principles, united with them, but diluted in a very great proportion of Water; and, they univerſally owe the activity the whole poſſeſſes, to the incorporation of the volatile and ſugitive principles, both with the Water, and, with the groſſer ingredients, combined together moſt intimately.

[23]

THE taſte of the Walton Water, freſh from the Spring, as has been already obſerved, is at firſt ſoft, and afterwards agreeably Saline; the Sulphur and Iron, are alſo plainly taſted in it, in the quantity of a pint, and, often leſs, it occaſions two or three lax ſtools, and, operates without the leaſt ſickneſs, griping or any kind of inconvenience.

THE quantity of urine is alſo encreaſed: it ſits eaſy on the ſtomach, and appetite is promoted.

THE volatile principles fly off, ſoon after the Water is removed from the Well; and, as theſe are ſo eſſential to its efficacy, and, render it agreeable to the taſte and ſtomach, and carry the Saline, invigorating, and deobſtruent contents of the Water into the veſſels and glands; it is neceſſary to drink it from the Pump, or very ſoon afterwards.

THESE Waters not only remove coſtiveneſs, but encreaſe appetite, and the powers of digeſtion, The chylification of digeſted aliment is more perfectly elaborated, and, the errors of the firſt digeſtion prevented, and remedied in an effectual manner; whatever is injurious to health in the ſtomach and and inteſtines, acidity, and [...]ilious putrid matter are carried out of the body. Worms, and their nidus [24]are expelled. In this manner the ſeeds of diſeaſe will be prevented in the chyliferous veſſels; and the Chyle itſelf being highly elaborated, and, withal, diluted with the Water, enters the lacteals, poſſeſſing ſuch qualities and powers, as bid fair to obviate, and remove obſtructions which have taken place in the channels of the chyle and lymph.

HENCE, obſtructions in the meſentery and glands will gradually be reſolved, as this Water will be likely to dilute and diſſolve any tenacious matter, incapable of moving in the chyliferous veſſels, on account of its glutinous, cheeſe-like, and, ſteatomatous conſiſtence, and, will ſtimulate the veſſels, and, meſenteric glands, by its Saline contents, ſo as to enable them to puſh on any obſtructing matter.

SOME portion of the Waters, being abſorbed, will act as a powerful deobſtruent in obſtructions of the liver.

BY thinning the Hepatic bile, and, carrying that fluid regularly into the inteſtines. By preventing the ſtagnation of bile in the gall-bladder. By gently ſtimulating the biliary veſſels, and encreaſing their action. In a word, by the united inſluence of theſe powers, recent obſtructions, or older ſcirrhoſities, which have taken place either at home, or by reſidence in warm climates, will be remodied.

CALCULOUS concretions in the biliary ducts, and, in the gall-bladder, when of a ſize capable of being [25]carried into the inteſtines, will be diſpoſed to be moved thither, by that ſtimulus, which acting originally on the duodenum, will extend its influence along the Ductus Choledochus. In like manner, new concretions of the biliary kind, will be effectually prevented.

So that this Water will be found a very effectual remedy for jaundice ariſing from gall-ſtones, as well as from other cauſes, obſtructing the diſcharge of the bile into the inteſtines. It will alſo be found uſeful in removing obſtructions in the ſubſtance of the Liver; and, in preventing hemmorrhoidal, and other diſcharges of blood, which moſt frequently originate from obſtructions in the Liver.

HEMMORRHOIDAL ſwellings, and diſcharges of blood from other cauſes, obſtructing, or retarding its motion, and, return through the branches of the vena portarum, will be eaſed or relieved by a ſeaſonable uſe of this Water.

THE ſoftneſs, which is peculiar to this Water, renders it proper in diſeaſes of the urinary paſſages; as it acts powerfully on the Kidneys, and occaſions an encreaſed ſecretion there, as well as in the inteſtinal tube; gravelly concretions will be prevented or waſhed away. As the ſecretion of urine is in experience, ſound eſſential, for carrying out of the body, the Salts and Oils, which are prejudicial to health; purity of blood will be very greatly promoted by the encreaſe of this ſecretion; ſo that by the free diſcharge [26]from this emunctory, along with that from the alimentary canal, the ſkin will be cleanſed from hot red eruptions, and, from ſcaly, and ſcabby incruſtations, which notoriouſly ariſe from a blood, and habit overloaded with acrid, and impure matter; when by exceſs in diet, or by improper food, by imperfect digeſtion, or inadequate ſecretion and excretion, ſuch acrid corrupt matter is formed, and retained in our bodies. Gentle evacuation, by the uſe of ſuch Waters, is generally a certain relief under theſe circumſtances; this has been experienced by various perſons, but very remarkably by one TANNER from Kidderminſter, who has had a leprous eruption removed from his face, and other parts, by drinking the Walton Water, and, applying it externally; which relief, for ſix years paſt, he had not obtained by any means whatever.

THE preſerving the bile in a fluid ſtate, and, the regular conveyance of it into the duodenum, will powerfully operate in compleating the digeſtion, and Chylification of the food; and, will give the blood thoſe properties, which ſupport the health, and, vigour of the body.—With that, all cutaneous ſoulneſs will diſappear, and, the bloom of beauty re-aſſume its charms, along with the eaſe, and cheerfulneſs inſeparable from wholeſome ſluids, and, from good health.

BY removing the ſomes, which cauſes Scurvies, Scrophulous, Herpetic eruptions, Leproſies, and, [27]every kind of cutaneous ſoulneſs, whether of the red, and pimply, or the ſcaly, and, ulcerous kinds; I ſay, by gradually draining off this fomes, and, ſoliciting its exit from the emunctories, ſuch foulneſſes of the ſkin, accompanied with itchings, ſores, and, even ſcirrhous, and, cancerous taints, will often be prevented, removed or palliated.

CHRONIC weakneſs, and, dejection of ſpirits, ariſing frequently from the ſame latent ſources, will receive relief from the ſalutary, though ſlow operation of theſe Waters.

OBSTRUCTIONS in the uterine ſyſtem, ſuppreſſions of the menſtrual diſcharge, and, other irregularities, and, exceſſes peculiar to it; the fluor albus, ſcirrhous tumours, and other diſeaſes of the womb, will in many circumſtances and conſtitutions, find a uſeful remedy in the Walton Water.

OBSTRUCTIONS left by the long continuance, and, the frequent return of intermittent fevers, will, probably, yield to a prudent uſe of theſe Waters; and, they will prepare the patient, and, put him in a fit ſtate to receive further benefit from the Bark.

OBSTRUCTIONS in the Lungs, from a ſcorbutic cauſe, and, acrid humours in the blood, and inveterate ophthalmia's, have been relieved, and, are likely to be ſucceſsfully treated by the Walton Water.

I SHALL not give many directions concerning the [28]uſe of this Water, profeſſedly ſimilar to that of Cheltenham, the method of drinking, of which, has been long aſcertained by eſtabliſhed uſage, and, the public is poſſeſſed of the directions of eminent, and, able practitioners explanatory of their experience, in this point.

THE Summer Months are the ſeaſon to drink the Walton Waters; as they will, in theſe months, and, in dry weather be in their moſt perfect ſtate of impregnation.

LIKE Cheltenham, the Walton Waters are their own preparative; three quarters of a pint, drank at the Pump, may be taken in the morning, and afternoon, this quantity may be encreaſed to three half-pints afterwards, if the former quantity does not ſufficiently open the body.

BUT I would obſerve, that the middle doſes, ſuch as merely preſerve the body in a lax ſtate, not exceeding three ſtools daily, are preferable to larger doſes, and to greater evacuation; the buſineſs and intention, being to carry off the ill-digeſted remains of meals, perhaps of exceſs, and of luxury, and, of all kinds of corrupt recrementitious matter lodged in the alimentary canal, without impairing ſtrength and digeſtion.

EARLY hours are neceſſary to an advantageous uſe of the Waters at the Well, where only they are drank without the loſs of the active Volatile ingredients, [29]which give power to thoſe that are more fixed, to penetrate into the glands, and ſmalleſt veſſels.

EXERCISE ſub dio, is alſo equally proper to ſecond the operation of the Water, and to ſtrengthen the body.

AN eaſy digeſted nutrient diet, conſiſting, when it agrees with the ſtomach, of milk in the morning and at night, of light meats and vegetables at dinner, with general temperance, and moderation in the uſe of vinous liquors, rather than total abſtinence from them, is highly expedient.

IN a ſituation, where excellent fiſh is ſo plentiful, it is proper to obſerve, that moderation in this article will be prudent, as a very frequent uſe of fiſh is found often prejudicial in diſcaſes of the ſkin, and, ſometimes produces the more obſtinate diſeaſes of that claſs; diſeaſes, for which theſe Waters are peculiarly proper.

IT is almoſt ſuperfluous to add, that, however uſeful it may be to entertain the mind with pleaſing ſociety, and, an agreeable ſucceſſion of amuſements, it is always neceſſary to retire to reſt at an early hour, and, before eleven o'clock at fartheſt to be in bed, that the conſtitution may have the advantage of nature's ſweet reſtorer, balmy ſleep.

IN the cutaneous diſeaſes, and, many of the affections of the glands, for which the internal uſe of theſe Waters is proper; Baths of different degrees of [30]heat from that of common cold Water, to that of one hundred degrees of Fahrenheit's ſcale, will be highly expedient; this will appear in a ſtronger light, from what I ſhall offer concerning the ſunctions, and diſeaſes of the lymphatic glands. I apprehend, the diſeaſes of theſe glands, are chiefly to be reached by the means of remedies, which are applied, ſo as to be abſorbed by the lymphatic veſſels, which paſs to the glands. I am confident, that the moſt obſtinate cutaneous, and glandular diſeaſes would yield to a due perſeverance in the external and internal uſe of Waters and other proper remedies. But what theſe remedies are, and, alſo the uſe, whether external or internal of Mineral Waters, and of Medicines of all kinds, which are to produce any important and ſalutary conſequence, can only be determined in particular caſes, and conſtitutions, by the judgment of an able, and experienced phyſician.

THOUGHTS ON THE FUNCTIONS AND DISEASES OF THE LYMPHATIC GLANDS.

[][1]

THE uſe of Mineral Waters in diſeaſes of the glands, leads me to offer ſome thoughts, which, I believe, are either new, or have not been enough attended to, concerning the uſe, and diſeaſes of the lymphatic glands.

THE lymphatic ſyſtem, which makes an important article in the anatomical diſcoveries of the laſt century, has received much improvement in this. It is not my buſineſs to aſſign to each improver or diſcoverer, his due proportion of merit. I acknowledge my obligations to them all. To Haller, Meckel, Monro, Mr. Hewſon, Dr. William Hunter, and Mr. John Hunter, Mr. Sheldon, and Mr. Cruikſhank; who have all contributed, and, ſome of them very ſplendidly, to perfect the knowledge of this important part of the animal ſyſtem; and, let them not deem it amiſs, that profiting by their labours, I endeavour to make them ſubſervient to the knowledge of the animal oeconomy, and to the healing art.

[2]

THAT the lymphatic veſſels ariſe from every viſcus, and, from every cavity in the body, as well as from the ſkin, and the cellular membrane inveſting the body, in prodigious, and till lately, in undiſcovered numbers, is an anatomical truth of the greateſt importance, now clearly demonſtrated, and univerſally acknowledged.

THE lymphatic veſſels, and lacteals are of the ſame kind, and, conſtitute a ſyſtem of veſſels, no where connected with the veins, containing red blood; but, which univerſally terminate in the lacteal ſac and duct, and convey chyle, and lymph collected in every part into the ſubclaviam vein, where it mixes with the blood, and no where elſe.

THE, ſole and excluſive function of this ſyſtem of veſſels is abſorption.

SOME, indeed, have held, that the red veins are ſupplementary abſorbents, eſpecially on ſome occaſions; and the illuſtrious Walther and others, with ſome probability, have aſſigned this office to the vena portarum, eſpecially in diſeaſes, in which the conglobate glands of the meſentery are ſcirrhous, or obliterated by age, as ſome have ſuppoſed, or, the lacteal ſac, and duct itſelf is obſtructed. The proofs of this are equivocal, and accounted for on different principles, by the ſchool of Hunter, particularly, by that accurate anatomiſt, Mr. John Hunter, who firſt diſcovered that abſorption is carried on by the lymphatic veſſels alone.

THE lacteal, and lymphatic veſſels univerſally paſs through conglobate glands, before the fluid they convey, reaches the lacteal duct; thoſe ariſing from the inteſtines, enter the different orders of meſenteric glands, and, the chyle and lymph depoſited in theſe glands, is again abſorbed from them by the vaſa lymphatica efferentia, in order to be conveyed to the thoracic duct.(d)

THIS law is univerſal, and, the lymphatic veins wherever they ariſe, in no inſtance enter into the lacteal duct, without previouſly, and repeatedly throwing the lymph into the conglobate glands, which are an eſſential part of this ſyſtem, a part of the greateſt importance, for the advantage of which, the lymph is abſorbed, in order to be conveyed to them; and from them the lymph is taken up in a more purified, and aſſimilated ſtate, and is conveyed by the lymphatica efferentia into the lacteal ſac and duct.

THE ſtructure of theſe glands is both vaſcular and cellular; into theſe cells the lymph is thrown, and the abſorbing lymphatics, the lymphatica efferentia, are the only excretories, to all the conglobate glands; the uſes of which are acknowledged to be unknown and undiſcovered, by gentlemen to whom anatomiſts are ſo much indebted, Meſſrs. Sheldon and Cruikſhank, the lateſt improvers of the lymphatic ſyſtem.(e)

[4]

YET it is a matter not only intereſting in the ſcience of phyſiology, to aſcertain their uſe, but is likewiſe neceſſary to enable us to underſtand more perfectly the diſeaſes of the glands, and, to treat them with ſucceſs: we will therefore purſue the enquiry.

A FLUID is conſtantly exhaled into the cavities containing the viſcera; this fluid is liable to be altered, either by remora or mixture; the abſorption of this fluid is the function of the internal lymphatics, and, when it is prevented, either by obſtruction of the conglobate glands, or, by any other cauſe; Dropſies in the brain, thorax, pericardium, abdomen, and the widely diffuſed cellular membrane, ariſe.

THE lymph along with the chyle, and nutritious liquors prepared from the food in the inteſtinal [5]canal, is abſorbed by the lacteal and lymphatic veſſels, for they are the ſame; theſe fluids are immediately thrown into the meſenteric glands; and, they are more numerous there than in other parts, becauſe their office is peculiarly important, that of perfecting the chyle or nutritious fluid, extracted by digeſtion from food. That fluid is perfected by intercepting what is noxious in the cells of the conglobate glands, where it undergoes a digeſtion before it is abſorbed by the ſecond and third orders of the lacteal veſſels.

NUMEROUS lymphatic veſſels, ariſe alſo from the ſtomach, inteſtines, and from the glandular viſcera; from the pelvis, the bladder, and parts of generation, both in males and females; they obſerve the ſame law, and paſs through the iliac conglobate glands, or others before they enter the lacteal ſac; and, their uſe is the ſame, to intercept crude, noxious, unaſſimilated matter, which has been rendered unfit by diſeaſe, or other means to mix immediately, and unaltered, with the blood.

THE food we take in, and the air we breathe, while they convey the neceſſary ſupports of life, contain alſo the feeds of diſeaſe and death.

THE lymphatic veſſels, which ariſe in the mouth, and, from the trachea and lungs, (where their number is immenſe), convey the fluids they abſorb, with whatever extraneous matter has been taken up to the numerous conglobate glands of the neck, to the thyroid gland, thymus, and the glands of the lungs, [6]where it is digeſted before it reaches the thoracic duct.

IN young animals who take in their food by ſuction, in which action much is abſorbed by the lymphatics; the glands are very large, numerous and conſpicuous, the more perfectly to digeſt, and animaliſe the crude fluids received by ſuction, with the milk.

WHEN that period of life is paſſed over, the thyroid glands and thymus are not quite ſo neceſſary, and abate in ſize, but are never totally obliterated.

IN pointing out the buſineſs of purifying, and animaliſing lymph, as the function, of the conglobate glands in general, I believe I have diſcovered the uſe of the thymus in infants, and, of the thyroid glands, hitherto one of the hidden myſteries in anatomy.(f)

THE external ſurface of the body, is no leſs abſorptive, fluids are imbibed, thirſt abated, urine and weight encreaſed from thence. Garlick, externally applied is ſoon ſmelled in the breath. Turpentine gives the urine a violet ſmell. Variolous matter, and the venereal poiſon introduced by the ſmalleſt puncture, produce ſimilar diſeaſes, and, previous to univerſal infection and diffuſion, the inguinal and axillary glands, are ſwelled and inflamed by the paſſage of the poiſon into them. Mercury, the antidote [7]to this poiſon, alſo enters freely by the ſkin. Bliſters applied to the arms and ſhoulders inflame the axillary glands; thoſe of the neck in children, particularly are made hard and ſore by ulcers behind the ears, and in the head, and, by bliſters to thoſe parts.

ULCERS and punctures in the legs, and other parts, often occaſion ſwellings along the lymphatics up to, the axillae, or inguinal glands. Purulent bubos ariſe frequently from ſuch ulcers, and, from matter formed in the joints. The axillary glands are ſwelled by ſtagnating milk, by cancerous ſwellings, and inflammations in the breaſt. Cancers in the lips and on the face, cauſe ſimilar ſwellings under the lower jaw, and, in the neck. The ſame glands are ſwelled by gum boils, and by venereal ſores in the lips. Acrid matter abſorbed, inflames the lymphatic veſſel, and, the gland, univerſally, between the ſeat of the matter and ſore, and, the thoracic duct; and, its entrance into the body, may be prevented by cauſtic, or, by the exciſion of the part. Powders ſcattered over the ſurface of the body are abſorbed, thus calomel is known to enter; and, I remember a degree of ſalivation, and ſore mouth, produced by a ſmall quantity of corroſive ſublimate, rubbed with crude ſal armoniac and camphire ſcattered on bed linen, in order to prevent a morbus pediculoſus.

WHEN we conſider theſe various facts, that all lymphatic veſſels perpetually enter the conglobate [8]glands, and, in the cells, of which theſe glands univerſally conſiſt, depoſite the lymph, which being abſorbed once, and, again by larger lymphatics, is at length conveyed by the great channel, the lacteal duct, into the vena cava deſcendens, under the left calavicle. When we recollect, that the Venereal Virus, Cancerous and Variolous poiſons, enter the body by theſe channels, and, and are primarily depoſited in theſe glands, occaſioning there tumours, ſometimes indolent, ſometimes painful, inflamed and ſuppurating. It ſeems clear, theſe glands are intended by nature, to purify the lymph, before it enters the blood veſſels, from matter, which may be noxious there, by arreſting it in the glands, univerſally connected with abſorbents.

IN theſe glands, it is either altered by a concocting, and digeſting power inherent in them, or when it is too noxious to be ſubdued into a ſalutary nature it remains in the form of a tumour, or eſcapes by ſuppuration. When it cannot be ſubdued, nor removed by ſuppuration, and, thoſe ſalutary efforts of nature fail, it is then abſorbed, and, diffuſes diſeaſe in the conſtitution at large.

THUS the glands in the neck, and the thyroid are interpoſed to intercept crude matter, or noxious Virus taken up from the noſtrils, mouth, trachea and lungs, and other parts about the neck and breaſt, more eſpecially in very young animals.

THE meſenteric glands purify, and digeſt, whatever [9]is abſorbed with the lymph and chyle from the inteſtines.

THE axillary, and inguinal glands, alter and intercept whatever extraneous matter may happen to be abſorbed from the ſurface of the body, or the cellular membrane.

THE glands have the power of aſſimilating into a ſound fluid, ſuch noxious matter, in very many inſtances. But when it is highly virulent as in the lues, in ſcrophulous, and in cancerous diſeaſes, that digeſting and aſſimilating function is overpowered, the gland remains ſcirrhous, or, is deſtroyed by ſuppuration, and, the matter enters, and contaminates the habit.

IN fine, the uſe of theſe glands is to intercept as ſponges, and to alter as digeſtive organs, whatever is unfit to enter into the maſs of blood. In ordinary caſes, this is effected without obſtruction, or, inflammation, and, then no apparent conſequences detrimental to health appear, and, the depoſited matter is abſorbed again, and, goes along with the ſound lymph. In extraordinary caſes, the poiſon remains in the gland, and, deſtroys its powers firſt, and its ſubſtance, and organization afterwards.

THE fatal conſequences, which have followed injections of undigeſted alimentary fluids, directly into the red veins of living animals, are proofs that the lymphatic glands have the uſe and function here [10]alledged, and, ſhow, that without the lymphatic digeſtion, liquors apparently harmleſs, are unfit to mix with the blood; and, produce fatal effects there.(g)

HOW the glands alter, digeſt, and aſſimilate the matter abſorbed, and depoſited in them, I know not, and ſhall not attempt to explain; I think that power implanted in them, as well as in the ſtomach and inteſtines; and, we ſee an important apparatus, ſet apart for the purpoſe, by Him! whoſe ability is too great, in every inſtance to be fully comprehended, and interpreted by us his creatures.

FROM the uſes here aſcribed to the lymphatic glands we ſee, why they are moſt numerous, where abſorption is greateſt; and, particularly in thoſe parts, where crude matter is abſorbed. We ſee, why the glands are nearly as numerous in the neck as in the meſentery(h); for beſide the matter abſorbed from the inſide of the mouth, noſtrils, and trachea; the abſorbents from the brain join the glands of the neck. Though theſe have not been traced by anatomiſts; as a copious exhalation, and, abſorption conſtantly take place in the ventricles of that organ; as we have reaſon to believe, the Water in the internal hydrocephalus is ſometimes abſorbed; from the general law, we may preſume, that lymphatics exiſt in the brain, though not certainly traced there(i); this is confirmed by the internal [11]cephalus often happening in ſcrophulous and ricketty children, in whom the glands of the neck are ſcirrhous.

IT is well known, that ſwellings of the glands often follow cruptive diſeaſes. They ariſe after ſcarlet fever, meaſles and ſmall pox. Dropſy, is ſometimes the conſequence of them all. And I have known the hydrocephalus internus, as well as other Dropſies ſucceed the ſcarlet fever; another preſumptive proof, that abſorption in the brain, is carried on by lymphatic veſſels, as well as in other parts.

WE alſo, ſee why the glands are more numerous in the meſentery, through which all the chyle paſſes and are ſmaller, and leſs numerous in the meſocolon, through which hardly any chyle paſſes, whence Mr. Cruikſhank is led to ſay, "this looks as if the glands were intended to produce ſome remarkable change in the chyle"(k).

THE meſenteric glands, as well as the conglobate glands in other parts, being cellular, as well as vaſcular, contain a white milky fluid, moſt conſpicuous and abundant in young animals. Album perpetuo reperi, ſays, Haller, Elem. Phyſ. T. 1.

THESE glands, though greatly leſs in adults than in young animals, are yet not totally obliterated. The illuſtrious Haller, has ſeen the thymus in the mediaſtinum, and the glands in the meſentery, and in [12]the inteſtinum rectum in adults; in children, they are very large and ſucculent, Elem. Phyſ. T. 1. p. 192.

THE lymphatic veſſels being deſtitute of the moving impulſe of the heart, and having no other principle of motion to carry on the liquors abſorbed, but that of the irritability of the lymphatic ſyſtem, the motion of the lymph is neceſſarily liable to be obſtructed. Hence obſtructions happen more frequently in the conglobate and lymphatic glands, than in the conglomerate glands. The liver may be excepted, becauſe the blood conveyed into it by the vena portarum, undergoes a ſimilar retardation in that very ſingular vein.

THE conglobate glands, are hence univerſally liable to ſcirrhoſity and obſtruction. The meſenteric glands are notoriouſly liable to great enlargement and hardneſs, and thereby often cauſe a ſlow conſuming ſever and atrophy in infants. Similar ſwellings in the meſenteric glands are ſometimes obſerved from ulcerated inteſtines after dyſentery. The neck is ſeldom ſtrumous without accompanying obſtructions in the meſenteric glands.

THE thyroid axillary and mammary glands, as well as the iliac lumbar and inguinal glands are all frequently ſound obſtructed and ſcirrhous. In a word theſe glands are not only obſtructed in venereal and cancerous habits; but the ſcrophula and rachitis likewiſe originate in them, and are principally ſeated in the glands.

[13]

IN all caſes of obſtructed glands, the chyle and lymph, being imperfectly aſſimilated, the blood becomes gradually vitiated, and, unfit for nouriſhment. Hence that acrimony often called ſcorbutic; an ulcerous and even cancerous diſpoſition of fluids originate. From the ſame ſource the bones become brittle, break in ſome, and are rendered ſoft and flexible in others.

ALL theſe facts conſpire to ſhew the importance of the digeſtive, and aſſimilating power of the glands, and, lymphatic ſyſtem, in perfecting the animal fluids.

IN diſeaſed glands, the chyle is not ſufficiently aſſimilated, and, that defect gradually induces acrimony, and impurity in the lymph, which ſoon taints the blood and habit univerſally.

IT is more from this defect, than from the entrance of the chyle into the blood, being prevented by obſtruction, that maraſmus, and conſumption follow ſcirrhoſities in the meſentric glands.

‘"IT is poſſible,"’ ſays, the ingenious Cruikſhank, ‘"that children, and, even grown perſons, may have died of the tabes meſenterica from obſtructions in the glands, rendering them impervious to the chyle."’ But he never ſaw any ſuch ſtagnation of chyle, as theſe are ſuppoſed to cauſe, on any occaſion whatever.(l)

[14]

THE lymph, and chyle, enter the blood but in a corrupted, crude, unanimaliſed ſtate.

I AM confirmed in this opinion, by the experiments of another excellent Anatomiſt, Mr. Sheldon, which I ſhall quote from his ſplendid Hiſtory of the Human Lacteal Veſſels.

IN ſubjects, in which the lymphatic glands of the meſentery, were found entirely obſtructed, ſometimes by a curd-like ſubſtance, ſometimes by calcareous earth, Mr. Sheldon, could puſh injections of quickſilver from the veſſels, below the obſtructed glands, to thoſe above them, though not a ſingle particle of quickſilver, could be made to enter the glands in this obſtructed ſtate. In this caſe, the collateral branches of the lacteal veſſels, which communicated with thoſe above, were enlarged, and, had conveyed the chyle into the lacteal duct.

THE ingenious Dr. Cheſton, found the cavity of the lacteal duct totally obſtructed for a conſiderable length, by an earthy matter, in a man who had a Spina Ventoſa of the os ilium.

IT is probable, the chyle, in this caſe, was conveyed from below, into the lacteal duct, above the obſtruction, by one or more collateral anaſtomoſing branches, which are every where numerous in the lymphatic veſſels, and, frequent in the lacteal duct itſelf. This being a proviſion of nature, for ſecuring more certainly, a regular conveyance of the chyle into the blood veſſels.

[15]

I remember a melancholy caſe, which ſhews the thoracic duct, ſometimes is obſtructed in a fatal degree; a young lady, high in rank, beautiful in perſon, and amiable in diſpoſition; had a ſwelling in the neck, which extended itſelf under the left clavicle, and there obſtructed the entrance of the thoracic duct into the ſubclavian vein ſo completely, as to render her incurably dropſical in every part of her body.

WHAT I have now offered, concerning the uſe of the glands, belonging to the lymphatic ſyſtem, will, I apprehend, derive ſupport from the late diſcoveries, and will be found uſeful in the treatment of diſeaſes of the glands.

MEDICINES taken into the ſtomach, and mixed with the chyle, are, indeed, in the direct channel, to reach the diſeaſed glands of the meſentery.

BUT this is not the caſe, reſpecting the conglobate glands in other parts. Medicines mixing with the blood never directly reach theſe glands. and, but very remotely, and indirectly affect them; and, this is one of the reaſons why, diſeaſes in theſe glands, have always appeared ſo ſtubborn, and have ſo rarely yielded to the common treatment, and internal uſe of Medicine.

THE confiding alone to Medicines, conveyed by the lacteals into the channel of circulation; the inattention to the only entrance into the external diſeaſed [16]glands, that by abſorption, are I am perſuaded, cauſes why thoſe diſeaſes have proved ſo obſtinate, and rebellious to Medical treatment.

IT is the cauſe why ſcrophula, and ſcirhous glands, have become cancerous, and finally incurable and fatal.

IT is evident then, that the remedies proper for removing obſtructions ſhould be applied to ſuch parts, from whence the lymphatics ariſe which may abſorb and conduct them to the glands, the obſtructions of which are to be removed.

APPLICATIONS intended to remove glandular ſwellings in the neck, the thyroid gland, the bronchocele &c. muſt be made to the head, neck, cheeks, and mouth internally, as well as externally.

VAPOURS inhaled by inſpiration, are proper in the diſeaſed glands of the lungs.

REMEDIES intended to paſs into the axillary glands, muſt be applied to the arms and breaſt.

IN diſeaſes of the inguinal glands the remedies intended to paſs into them, and through them, muſt be applied to the genitals, and to the legs and thighs.

THE advantages found from the local application of Mercury in Venereal ſwellings of the inguinal, and axillary glands, and in ulcers of the throat, exemplify this doctrine in that diſeaſe.

[17]

THE holding Medicines intended to remove the the bronchocele, and ſwelled neck, in the mouth and under the tongue, is eſſential to give efficacy to theſe Medicines, as has been long experienced, in the Coventry Medicine. The ſaline ingredients, whether alcaline, or neutral, of which ſuch Medicines uſually conſiſt, are abſorbed by the lymphatic veſſels ariſing in the inſide of the mouth, and, are conveyed directly to the diſeaſed glands with conſtant good effect.

INTERNAL obſtructions in the meſentery in particular, are to be relieved by internal Medicines; and in every kind of glandular obſtruction Mineral Waters have been found highly neceſſary and uſeful.

THE Chalybeate, the ſulphureous, the ſaline, the hot, and the cold Waters, have all been tried with advantage.

OF laxative Medicines, the purgative Mineral Waters, always operate with the leaſt diminution of ſtrength, and with the leaſt diſturbance; the appetite is for the moſt part mended under their uſe, and important alterations in the whole ſyſtem, ariſe from continuing to apply to them. Their operation principally affects the firſt paſſages in clearing away what is recrimentitious, and hurtful in that ſeat and ſource of corruption.

THEY next directly operate on the lacteal veſſels and glands; they dilute the chyle, and ſtimulate the [18]lacteals themſelves, which are ſufficiently irritable; and remove thereby, both the ſource of obſtruction, and the obſtructions, which may have taken place, in the conglobate glands of the meſentery.

IN this manner they contribute to the purity, and perfection of the chyle and lymph, and remove all obſtacles, to its perfect digeſtion in the inteſtinal canal, and in the lacteal veſſels and glands.

HENCE this ſource of tainted fluids being taken away from the chyle and blood, and no new acrimonious depoſition falling on the remoter parts of the body; the lymphatic veſſels and glands, there reaſſume their functions, and, abſorb and digeſt, what was before lodged on the ſkin, and on the adjacent parts of the ſurface of the body.

THUS, under the uſe of ſuch Waters, continued for a ſufficient length of time, depoſitions, eruptions and defedations of the ſkin, with ulcers and glandular ſwellings diſappear. It is thus the Harrowgate, Cheltenham and Walton Waters prove beneficial.

THE Sea Water, acts not only as a powerful internal remedy in the ſame diſeaſes; but has its efficacy greatly promoted by bathing; waſhing thereby away much cutaneous foulneſs, and removing more by being directly abſorbed into the lymphatic's, and conveyed to the diſeaſed glands; at the ſame time, that a uſeful ſpring and vigour is given to the whole conſtitution.

[19]

I MIGHT illuſtrate the practical importance of theſe principles by caſes, but this letter being already too long, I now commit it to your conſideration. To you! who joining reading to experience and talents, make the healing art your ſtudy and delight.

FROM you, my humble but zealous endeavours to excite the attention of the younger and liberal Gentlemen of the profeſſion, to improved methods of curing diſeaſes, are ſure of a candid reception.

As to others whoſe ſole purſuit and ſtudy is gain;

Quaerenda pecunia primum eſt, Virtus poſt nummos.

I HAVE not wrote for them, and have certainly no attention to expect from them.

The ingenious diſcoverers, who have lately ſo much improved the knowledge of the lymphatic ſyſtem, all acknowledge their ignorance of the uſe of theſe glands. Mr. Cruikſhank, the lateſt publiſher on this ſubject, ſays, ‘"Though we know ſomething more of the nature, ſtructure and diſeaſes, of the lymphatic glands, we know no more of their real uſe than the ancients. As they inform us, however, of the paſſage of infections matter into the blood; and as from their ſtate, we are enabled to judge of the preſence or abſence, of other diſeaſes the knowledge of them is of great importance, in the practice of medicine."’ ANATOMY OF THE ABSORBING VESSELS OF THE HUMAN BODY, p. 68, 69.
