CCCCXXXIII. this difeafe there are two fpecies, the one named the Acute, the other the Chronic rheumatifm. Vol. II. B CCCCXXXIV. 10 PRACTICE cccCxxxiv. It is the Acute Rheumatifm which efpe- cially belongs to this place, as from its caufes, fymptoms, and methods of cure, it will appear to to be a fpecies of phleg- mafia or inflammation. ccccxxxv. This difeafe is frequent in cold, and more uncommon in warm, climates. It appears moft frequently in autumn and fpring, lefs frequently in winter when the cold is confiderable and conftant, and very feldom during the heat of fummer. It may occur, however, at any feafon, if vi- ciffitudes of heat and cold be for the time frequent. CCCCXXXVI. The acute rheumatifm generally arifes from OF PHYSIC. 11 from the application of cold to the body when any way unufually warm; or when one part of the body is expofed to cold whilft the other parts are kept warm; or laftly, when the application of the cold is long continued, as it is when wet or moift clothes are applied to any part of the body. CCCCXXXVIL Thefe caufes may affetft perfons of all ages; but the rheumatifm feldom appears in either very young or in elderly perfons, and moft commonly occurs from the age of puberty to that of thirty-five years. CCCCXXXVIII. Thefe caufes (CCCCXXXVI.) may alfo affect perfons of any conftitution ; but they moft commonly affect thofe of a fan- guine temperament. B 2 CCCCXXX1X. PRACTICE 12 CCCCXXXIX. This difeafe is particularly diftinguifhed by pains affecting the joints, for the moft part the joints alone, but ibmetimes affect- ing alfo the mufcular parts. Very often the pains fhoot along the courfe of the mufcles, from one joint to another, and are always much increafed by the action of the mufcles belonging to the joint or joints affected. CCCCXL. The larger joints are moft frequently affected; fuch as the hip-joint, and knees of the lower, and the Ihoulders and elbows of the upper, extremities. The ankles and wrifes arealfo frequently affedled; but the fmaller joints, fuch as thole of the toes or fingers, feldom fuller. CCCCXLI. OF PHYSIC. 13 CCCCXLI. This difeafe, although fometimes coii'- fined to one part of the body only, yet very often afiedls many parts of it; and then it comes on with a cold ftage, which is im- mediately fucceeded by the other fymp- toms of pyrexia, and particularly by a fre- quent, full, and hard pulfe. Sometimes the pyrexia is formed before any pains are perceived; but more commonly pains are felt in particular parts, before any fymp- toms of pyrexia appear. CCCCXLII. When no pyrexia is prefent, the pain is Sometimes confined to one joint only; but, when any confiderable pyrexia is prefent, although the pain may be chiefly in one joint, yet it feldom happens but that the pains aflcdt feveral joints often at the very S3 fame 14 PRACTICE fame time, but for the moSt part Shifting their place, and, having abated in one joint, become more violent in another. They do not commonly remain long in the fame joint, but frequently Shift from one to an- other, and fometimes return to joints for- merly affedfed; and in this manner the difeafe often continues for a long time. CCCCXLIII. The pyrexia attending this difeafe has an exacerbation every evening, and is mod considerable during the night, when the pains alfo become more violent; and it is at the fame time that the pains fhift their place from one joint to another. The pains feem to be alfo increafed during the night, by the body being covered more clofely, and kept warmer. CCCCXLIV. OF PHYSIC. 15 CCCCXLIV. A joint, after having been for fome time affedled with pain, commonly becomes af- fected alfo with fome rednefs and fwelling, which is painful to the touch. It feldom happens, that a fwelling coming on does not alleviate the pain of the joint; but the fwelling does not always take off the pain entirely, nor fecure the joint againft a return of it. CCCCXLV. This difeafe is commonly attended with fome fweating, which occurs early in the courfe of the difeafe; but it is feldom free or copious, and feldom either relieves the pains or proves critical. B 4 CCCCXLVL 16 PRACTICE CCCCXLVI. In the courfe this difeafe the urine is high coloured, and in the beginning with- out fediment; but as the difeafe advances, and the pyrexia has more confiderable re- miflions, the urine depofits a lateritious fe- diment. This, however, does not prove entirely critical; for the difeafe often con- tinues long after fuch a fediment has ap- peared in the urine. CCCCXLVII. When blood is drawn in this difeafe, it always exhibits the appearance men- tioned CCXXXVII. CCCCXLVIII. The acute rheumatifm, though it has fo much of the nature of the other phleg- jnafiae, OF PHYSIC. 17 mafias, differs from all thofe hitherto mentioned, in this, that it is not apt to terminate in fuppuration. This ai- med: never happens in rheumatifm; but the difeafe fometimes produces effufions of a tranfparent gelatinous fluid into the {heaths of the tendons. If we may be al- lowed to fuppofe that fuch eflufions are fre- quent, it muft alfo happen, that the efiufed fluid is commonly reabforbed; for it has feldom happened, and never indeed to my obfervation, that confiderable or perma- nent tumours have been produced, or fuch as required to be opened, and to have the contained fluid evacuated. Such tumours, however, have occurred to others, and the opening made in them has produced ul- cers difficult to heal. Vide Storck. Ann. Med. II. CCCCXLIX 18 PRACTICE CCCCXLIX. With the circumftances mentioned from CCCCXXX1X. to CCCCXLVIII. the dif- eafe often continues for feveral weeks. It feldom, however, proves fatal; and it rarely happens that the pyrexia continues to be confiderable for more than two or three weeks. While the pyrexia abates in its violence, if the pains of the joints con- tinue, they are lefs violent, more limited in their place, being confined commonly to one or a few joints only, and are lefs ready to change their place. CCCCL. When the pyrexia attending rheuma- tifm has entirely ceafed ; when the fwell- ing, and particularly the rednefs of the joints, are entirely gone ; but when pains ftill continue to affedl certain joints, which OF PHYSIC. 19 which remain diff, which feel uneafy upon motion, or upon changes of weather, the difeafe is named the Chronic Rheuma- tifm, as it very often continues for a long time. As the chronic is commonly the fequel of the acute rheumatifm, 1 think it proper to treat of the former alfo in this place. CCCCLI. The limits between the acute and chro- nic rheumatifm are not always exactly marked. When the pains are dill ready to fhift their place; when they are efpecially fevere in the night-time; when, at the fame time, they are attended with fome degree of pyrexia, and with fome fwelling, and ef- pecially with fome rednefs of the joints; the difeafe is to be confidered as dill partaking the nature of the acute rheumatifm. But, 20 PRACTICE But, when there is no degree of pyrexia remaining; when the pained joints are without rednefs ; when they are cold and Iliff; when they cannot eafily be made to fweat; or when, while a free and warm fweat is brought out on the reft of the body, it is only clammy and cold on the pained joints ; and when, efpecially, the pains of thefe joints are increafed by cold, and relieved by heat applied to them; the cafe is to be confidered as that of a purely chronic rheumatifm. CCCCLII. The chronic rheumatifm may affect different joints; but is efpecially ready to affect thofe joints which are furroundcd with many mufcles, and thofe of which the mufcles are employed in the moft con- ftant and vigorous exertions. Such is the cafe of the vertebras of the loins, the af- fection OF PHYSIC. 21 fe&ion of which is named Lumbago; or that of the hip-joint, when the difeafe is named Ifchias, or Sciatica. CCCCLIII. Violent ftrains and fpafms occurring on fudden and fomewhat violent exertions, bring on rheumatic afFeddions, which at firft partake of the acute, but very foon change into the nature of the chronic rheumatifm. CCCCLIV. I have thus delivered the hiftory of rheumatifm; and fuppofe, that, from what has been faid, the remote caufes, the diag- nofis, and prognofis of the difeafe, may be underftood. The diftin&ion of the rheu- matic pains from thofe refembling them, which occur in the fyphilis and fcurvy, will 22 PRACTICE. will be obvious, either from the feat of thofe pains, or from the concomitant fymptoms peculiar to thefe difeafes. The diftindlion of rheumatifm from gout will be more fully underflood from what is to be delivered in the following chapter. CCCCLV. With refpecl to the proximate caufe of rheumatifm, there have been various opi- nions. It has been imputed to a peculiar acrimony; of which, however, in or- dinary cafes, I can find no evidence; and, from the confideration of the remote caufes, the fymptoms, and cure of the difeafe, I think the fuppofition very im- probable. The caufe of an Ifchias Nervofa affigned by Cotunnius, appears to me hypothe- tical, and is not fupported by either the phenomena or method of cure. That, however, OF PHYSIC. 23 however, a difeafe of a rheumatic nature may be occafioned by an acrid matter ap- plied to the nerves, is evident from the toothach, a rheumatic aftedtion generally ariling from a carious tooth. That pains refembling thofe of rheu- matifm, may arife from deep-fea ted fup- purations, we know from fome cafes de- pending on fuch a caufe, and which, in their fymptoms, refemble the lumbago or ifchias. I believe, however, that, by a proper attention, thefe cafes depending on fuppuration, may be commonly diftin- guifhed from the genuine cafes of lumba- go and ifchias ; and, from what is.faid in CCCCXLVIII. I judge it to be at leaft improbable, that a genuine lumbago or ifchias does ever end in fuppuration. CCCCLVI. The proximate caufe of rheumatifm has 24 PRACTICE. has been by many fuppofed to be a lentor of the fluids obftru&ing the veflels of the part; but the fame confideration as in CCXLI. i, 2, 3, 4, and 5, will apply equally here for rejecting the fuppofition of a lentor- CCCCLVII. While I cannot, therefore, find either evidence or reafon for fuppofing that the rheumatifm depends upon any change in the Rate of the fluids, I muft conclude that the proximate caufe of acute rheuma- tifm, is commonly the fame with that of other inflammations not depending upon a direct ftimulus. CCCCLVIH, In the cafe of rheumatifm I fuppofc, that the moft common remote caufe of it, that OF PHYSIC. 25 fliat is, cold applied, operates efpecially on the veffels of the joints, from thefe being lefs covered by a cellular texture than thofe of the intermediate parts of the limbs. I fuppofe further, that the application of cold produces a conftridlion of the extreme veffels on the furface, and at the fame time an increafe of tone or phlogiftic diathefis in the courfe of them, from which arifes an increafed impetus of the blood, and, at the fame time, a refiftance to the free paffage of it, and confequently inflam- mation and pain. Further, I fuppofe, that the refiftance formed excites the vis medicatrix to a further increafe of the impetus of the blood; and, to fupport this, a cold ftage arifes, a fpafm is formed, and a pyrexia and phlogiftic diathefis are produced in the whole fyftem. c Vol. II. CCCCLIX. 26 PRACTICE CCCCLIX. According to this explanation, the cauie of acute rheumatifm appears to be exactly analogous to that of the inflammations de- pending on an increafed afflux of blood to a part while it is expofed to the a&ion of cold. But there feems to be alfo, in the cafe of rheumatifm, a peculiar affedfflon of the fibres of the mufcles. Thefe fibres feem to be under fome degree of rigidity, and therefore lefs eafily admit of motion; and are pained upon the exertions of it. It is alfo an affedtion of thefe fibres which gives an opportunity to the propa- gation of pains from one joint to another, along the courfe of the mufcles; and which pains are more feverely felt in the extre- mities of the mufcles terminating in the joints, becaufe, beyond thefe,.the ofcilla- tions are not propagated. This OF PHYSIC. 27 This affection of the mufcular fibres at- tending rheumatifm, feems to explain why (trains and fpafms produce rheumatic af- fections ; and, upon the whole, {hows, that, with an inflammatory affection of the fanguiferous fyftem, there is alfo in rheumatifm a peculiar affeCtion of the mufcular fibres, which has a confiderable {hare in producing the phenomena of the difeafe. CCCCLX. Having thus given my opinion of the proximate caufe of rheumatifm, I proceed to treat of the cure. CCCCLXI. Whatever difficulty may occur with re- fpedt to the explanation given (CCCCLVIIL and CCCCLIX.) this remains certain, that C 2 in 28 PRACTICE in acute rheumatifm, at leaft in all.thofe cafes which do not arife from diredt fti- muli, there is an inflammatory affedtion of the parts, and a phlogiftic diathefis in the whole fyftem; and upon thefe is found- ed the method of cure, which frequent experience has approved of. CCCCLXII. The cure therefore requires, in the firft place, an antiphlogiftic regimen, and par- ticularly a total abftinence from animal food, and from all fermented or fpirituous liquors ; fubftituting a vegetable or milk diet, and the plentiful ufe of bland diluent drinks. CCCCLXIII, Upon the fame principle (CCCCL.) at lead with perhaps the fame exception as above OF PHYSIC. 29 above, blood-letting is the chief remedy of acute rheumatifm. The blood ought to be drawn in large quantity, and the bleeding is to be repeated in proportion to the frequency, fullnefs, and hardnefs of the pulfe, and to the violence of the pain. For the moft part, large and repeated bleedings, during the firfl: days of the dif- eafe, feem to be necefiary, and according- ly have been very much employed; but to this fome bounds are to be fet; for very profufe bleedings occafion a flow recovery and, if not abfolutely effe&ual, are ready to produce a chronic rheumatifm. CCCCLXIV. To avoid that debility of the fyftem, which general bleedings are ready to occa- iion, the urgent fymptom of pain may be often relieved by topical bleedings, and, when any fwell.ing and rednefs have c 3 PRACTICE 30 have come upon a joint, the pain of it may be very certainly relieved by fuch bleedings ; but, as the continuance of the difeafe feems to depend more upon the phlogiftic diathefis of the whole fyftem, than upon the affection of particular parts, fo topical bleedings will not always fupply the place of the general bleedings propofed above. GCCCLXV. To take off the phlogiftic diathefis pre- vailing in this difeafe, purging may be ufe- ful, if procured by medicines which do not ftimulate the whole fy ftem, fuch as the neu- tral faits, and which have, in fome meafure, a refrigerant power. Purging, however, is not fo powerful as bleeding, in removing phlogiftic diathefis ; and, when the difeafe has become general and violent, frequent ftoqls OF PHYSIC. 31 itools are inconvenient, and even hurtful, by the motion and pain which they occafiom CCCCLXVI. In acute rheumatifm, applications to the .pained parts are of little fervice. Fomenta- tions, in the beginning of the difeafe, rather aggravate than relieve the pains. The ru- befacients and camphire are more effectual in relieving the pains; but generally they only ihift the pain from one part into an- other, and do little towards the cure of the general afiedtion. Bliftering, applied to the pained part, may alfo be very effectual in removing the pain from it; but will be pf little ufe, except where the pains are much confined to one part. CCCCLXVII. The feveral remedies mentioned from C 4 (CCCCLL 32 PRACTICE (CCCCLI. to CCCCLV.) moderate the vio- lence of the difeafe, and fometimes remove it entirely; but they fometimes fail in this, and leave the cure imperfedf. The at- tempting a cure by large and repeated bleedings, is attended with many inconveni- ences, (fee CXL.) ; and the moft effec- tual and fafe method of curing this difeafe, is after fome general bleedings for taking off, or at leaft diminifhing the phlogiftic dia- thefisto employ fwcating, conduced by the rules laid down CLXVIII. and CLXIX. CCCCLXVIII. Opiates, except where they are diredled to procure fweat, always prove hurtful in every ftage of this difeafe. CCCCLXIX. The Peruvian bark has been fuppofed a remedy OF PHYSIC. 33 remedy in fome cafes of this difeafe; but we have feldom found it ufeful, and, in fome cafes, hurtful. It appears to me to be fit in thofe cafes only, in which the phlogiftic diathefis is already much abated, and where, at the fame time, the exacerba- tions of the difeafe are manifeftly periodi- cal, with confiderable remifiions inter- pofed. CCCCLXX. Calomel, and fome other preparations of mercury, have been recommended in the acute rheumatifm; but I believe they are ufeful only in cafes of the chronic kind, or at leaft in cafes approaching to the nature of thefe. CCCCLXXI. Having now treated fully of the cure of the 34 PRACTICE the acute rheumatifm, I proceed to treat of the cure of the chronic, which is fo fre- quently a fequel of the former. CCCCLXXII. The phenomena of the purely chronic rheumatifm, mentioned in CCCCXXXIX. and CCCCXL. lead me to conclude, that its proximate caufe is an atony, both of the blood-veflels and of the mufcular fibres of the part affeCted, together with a degree of rigidity, and contraction in the latter, fuch as frequently attend them in a Rate of atony. cccclxxiii. Upon this view of the proximate caufe, the general indication of cure muft be to reflore the activity and vigour of the vital principle in the part; and the remedies for OF PHYSIC. 35 for this difeafe, which experience has ap- proved of, are chiefly fuch as are mani- feflly fuited to the indication propofed. CCCCLXXIV. Thefe remedies are either external or in- ternal. The external are the fupporting the heat of the part, by keeping it conftantly co- vered with flannel; the increafing the heat of the part by external heat, applied cither in a dry or in a humid form; the diligent ufe of the flefh-brufh, or other means of friCtion; the application of electri- city in fparks or {hocks; the application of cold water by affiifion or immerflon; the application of eflential oils of the moft warm and penetrating kind; the appli- cation of fait brine; and, laftly, the em- ployment of exercife, either of the part itfelf, fo far as it can eaflly bear it; or of the 36 PRACTICE the whole body by riding, or other mode of geftation. CCCCLXXV. The internal remedies are, i. Large doles of eflential oil drawn from relinous fubftances, fuch as turpentine; 2. Sub- ftances containing fuch oils, as guaiac; 3. Volatile alkaline faits; 4. Thefe, or other medicines diredied to procure fweat, (GLXIX.); and, laftly, calomel, or other preparation of mercury, in fmall dofes, continued for fome time. CCCCLXXVL Thefe (CCCCLXIII, CCCCLXIV.) are the remedies fuccefsfully employed in the purely chronic rheumatifm; and there are ftill others recommended, as bleeding, general and topical, burning, bliftering, and OF PHYSIC. 37 and iflues ; but thefe appear to me to be chiefly, perhaps only, ufeful when the difl- eafe ftill partakes of the nature of acute rheumatifin. CHAP. 38 PRACTICE CHAP. XIII. Of the Toothach or Odontalgia. CCCCLXXVIL T Have formerly confidered this difeafe as a fpecies of Rheumatifm, to be treat- ed upon the fame principles as thofe de- livered in the preceding chapter; but now, from more attentive confideration, I am led to conlider the toothach as a diftindl difeafe. Whilft the moft of what has been delivered in the laft chapter proceeds upon the OF PHYSIC. 39 the fuppofition that the rheumatifm de- pends upon a certain ftate of the blood- veflels and of the motion of the blood in them, without this being produced by the irritation of any acrid matter applied; I judge, that in the toothach, though there dre often the fame circumftances in the ftate of the blood-veflels as in the cafes of rheumatifm, thefe circumftances in tooth- ach always arife from the application of an acrid matter to the nerves of the teeth. CCCCLXXVIIL This difeafe is often no other than a pain felt in a particular tooth, without any inflammatory affedion being at the fame time communicated to the neighbouring parts. This, however, is rarely the cafe; and for the moft part, together with the pain of the tooth, there is fome degree of pain and of inflammatory affedion com- municated PRACTICE 40 municated to the neighbouring parts, fome- times to the whole of thofe on the fame fide of the head with the affected tooth. CCCCLXXIX. This inflammatory affecflion feems to me to be always an affection of mufcles, and of the membranous parts connected with thefe, without any tendency to fup- puration; and fuch an affection, as is excited by cold in fimilar parts elfewhere. It is from thefe circumftances that I conclude the affection to be of the rheumatic kind. CCCCLXXX. It is poHible that the mufcles and membranes of the jaw may be affected by the fame caufes which produce the rheu- matifm in other parts; and it is alfo po£- fible, that a rheumatic diathefis at firft pro- 0 F PHYSIC. 41 produced by irritation, may fubfift in the mufcles and membranes of the jaw, fo that the inflammatory affedlion may be renew- ed by certain caufes without any new ap- plication of acrid matter: but I am per- fuaded that either of thefe occurrences are very rare, and I have never been able to afcertain any cafes of toothach to be of thefe kinds. I confider it, therefore, as high- ly probable that this rheumatic affection of the jaws which we name toothach, is al- ways dependent upon fome immediate application of acrid matter to the nerves of the teeth. CCCCLXXXI. It is however to be obferved, that this application of acrid matter does not always excite a pain in the tooth itfelf, or an in- flammatory affection of the neighbouring parts; but that it very often operates by Vol. II. D produ- 42 PRACTICE producing a diathefis only; fo that cold ap- plied to the neighbouring parts does excite both a pain in the tooth, and an inflam- matory affection of the neighbouring parts which did not appear before. There feem to be alfo certain dates of the body, which operate upon the fame diathefis, fo as to produce toothach. Such feems to be the cafe of pregnant women, who are more liable to toothach than other women. There are probably alfo fome cafes of increafed irritability which render per- fons more fubjedt to toothach. Thus wo- men are more liable to the difeafe than men, and particularly women liable to hy- fteric affedlions. CCCCLXXXII. The acrid matter producing this difeafc feems to be generated firft in the hard fubftances of the teeth, and as it often ap- pears OF PHYSIC. 43 pears fir ft upon the external furface of thefe, it might be fufpedled to arife from the application of external matters to the teeth: but as the production of this acri- mony is often begun in the internal cavity of the teeth, where the operation of external matters cannot be fufpecled, and as even when it begins upon the external parts of the teeth, the operation of the caufe is at firft in a fmall portion of the teeth only, that it isdif- ficult to fuppofe that any matter externally applied could act in fuch a partial manner; fo it is prefumed that the acrid matter occa- fioning the toothach is produced by fome vice originating in the fubftance of the tooth itfelf. When it begins upon the external furface, it is on the enamel; but upon the internal furface, it mu ft be in the bony part. From what caufes it arifes in either of thefe fubftances, I do not at ail know; but I fufpeCt that it often arifes from fome more general fault in rhe fluids of the D 2 body. 44 PRACTICE body. The frequent ufe of mercury, efpe- daily when thrown much upon the mouth, and the ftate of the fluids in feurvy, feem both of them to give a difpofttion to a caries in the teeth ; and it is poflible that fome other acrimonious ftates of the fluids may have the fame effect. CCCCLXXXIH. A caries in feme part of the teeth, whe- ther arifing upon their internal furface or upon their external proceeding fo far as to reach the nerves in the cavity of the teeth, is pretty manifeftly the caufe of toothach, and of the firft attacks of it; but when the cavity of the teeth has been opened, fo that the external air or other matters can reach that cavity, thefe are often the exciting caufes of toothach, and ferve to prove in general, that acrid matters applied to the nerves occafion the difeafe. CCCCLXXXIV. OF PHYSIC. 45 CCCCLXXXIV. What is the nature of the matter pro- duced in the caries of the teeth, I do not underhand, nor have I found any proper corrector of it; but I prefume it to be of the putrid kind, as it often taints the breath with a fetid odour. CCCCLXXXV. Jn the cure of this difeafe, a long experience has fhown, that the extraction of the carious tooth proves the moil ef- fectual, and very often the only effectual, remedy of the difeafe. But as in fome cafes this extraction is not proper, and as in many cafes it is obftinately avoided, other means of curing the difeafe, or at leaft of relieving the pain, have been fought for gnd much praCtifed. D 3 CCCCLXXXVL 46 PRACTICE CCCCLXXXVI. Among thefe remedies, thofe are like- ly to be the moft effectual which en- tirely deftroy the affedted nerve, or at leaft fo much of it, as is expofed to the adtion of the acrid matter in the tooth. When an opening is made into the cavity of the tooth, the nerve of it may be deftroyed moft certainly by the adtual cautery; and it may alfo poflibly be done by the appli- cation of potential cauftics, either of the alkaline or acid kind. CCCCLXXXVII. When thefe remedies cannot be ren- dered effectual, relief may often be ob- tained by diminifhing thefenfibility of the nerve affedted, by the application of opium, or of the more acrid aromatic oils, diredtly to the nerve in the tooth. It ap- pears OF PHYSIC. 47 pears alfo that the fenfibility of the affec- ted nerve may often be for fome time diminifhed by the external application of opium to the extremities of thofe nerves in the fkin, which are branches of the fame fifth pair of nerves with thofe of the teeth. CCCCLXXXVIII. When the difeafe conlifts entirely in a pain of the nerve of the tooth, without any conhderable affedion communicated to the neighbouring parts, the remedies al- ready mentioned are thofe efpecially to be employed; but when the difeafe coniifts very much in an inflammatory affedion of the mufcles and membranes of the jaw, and when at the fame time there is little or no accefs for the abovementioned re- medies to the affeded nerve, other mea- fures are to be employed for relieving the difeafe. D 4 CCCCLXXXIX. 48 PRACTICE CCCCLXXXIX. If the difeafe be attended with any ge- neral phlogiflic diathefis of the fyftem, or with any confiderable degree of pyrexia, a general bleeding may be ufeful in relieving the difeafe: but thefe circumftances occur very rarely, and the difeafe is for the moft part a purely topical afiedlion, in which, as I obferved before, a general bleeding is of very little fervice. As this difeafe, however, is a topical inflam- mation, it might be fuppofed that to- pical bleedings would be very ufeful, and fometimes they are fo; but it is fel- dom that their effects are either con- fiderable or permanent. The reafons of this I take to be, that the difeafe does not confift in an aflfedtion of the blood- veffels alone, as in the ordinary cafes of rheumatifm ; but in a peculiar af- fection of the fibres both of the paufclc? and O F P H Y S I C. 49 and of the veffels of the part induced by irritation. The inefficacy of topical bleed- ings is with me a proof of the difeafe being of the latter kind. CCCCXC. The remedies therefore neceffiary to give relief in this difeafe, are thofe which take off the fpafm of the veffels, and efpe- cially of the mufcles and membranes af- feded. Such are bliftering, brought as near to the part affeded as can be conveniently done; and fuch are alfo increafed excre- tions excited in the neighbouring parts, as of the faliva and mucus of the mouth by the ufe of acrid mafticatories. It is often fufficient, to excite a ftrong fenfation in the neighbouring parts; as by eau de luce, ipirit of lavender, or Hungary water, fnuffed up the noftrils; or by the vitriolic lethcr properly applied to the cheek. It is upon 50 PRACTICE upon the fame footing that I fuppofe brandy or other ardent fpirit held in the mouth is often of fervice. CCCCXCI. There are cafes of toothach in which it does not appear that the difeafe arifes from an acrid matter immediately applied to the nerve of a tooth; but from the exter- nal application of cold, or fome other caufes immediately applied to the mufcles and membranes of the jaw; and which therefore feem to require fome remedies different from thofe abovementioned. But in all fuch cafes, it is to be fufpecled, that the effects of cold or of other fuch caufes are owing to a diathefis produced by an acrid matter applied to the nerve of a tooth, and continuing in fome meafure to adt there; and we have accordingly often found, that the adtion of thofe external caufes were tQ OF PHYSIC. 51 to be obviated only by the extraction of the tooth from which the diathefis had arifen. CHAP. XIV. Of the Gout. CCCCXCIL THE Gout, not only as it occurs in different perfons, but even as it oc- curs in the fame perfon at different times, is a difeafe of fuch various appearance, that it is difficult to render the hiftory of it complete and exaCl, or to give a character of 52 PRACTICE of it that will univerfally apply. How- ever, I fhall endeavour to defcribe the dif- eafe as it moft commonly appears, and to mark the varieties of it as well as I can. From fuch a hiftory I expedt that a ge- neral character may be given; and fuch I think is the following, as given in the laft edition of our Nofology : Gen. XXIII. PODAGRA. Morbus hasreditarius, oriens fine caufa externa evidente, fed prseunte plerumque ventriculi affedtione infolita; pyrexia; do- lor ad articulum et plerumque pedis pollici, certe pedum et manuum jundluris, potifli- mum infeflus; per intervalla revcrtens, et fcpe cum ventriculi et internarum partium affedionibus alternans,. CCCCXCIII. The Gout is generally a hereditary dif- eafe; OF PHYSIC. 53 eafe; but feme perfons, without hereditary difpofition, feem to acquire it; and, in fome, a hereditary difpofition may be coun- teracted by various caufes. Thefe circum- ftances may feem to give exceptions to our general pofition; but the fads diredly fupporting it are very numerous. CCCCXCIV. This difeafe attacks efpecially the male fex; but it fometimes, though more rarely, attacks alfo the female. The females liable to it are thofe of the more robuft and full habits; and it very often happens to fuch long before the menftrual evacuation has ceafed. I have found it occurring in feve- ral females, whofc menftrual evacuations were more abundant than ufual. ccccxcv. This difeafe feldom attacks Eunuchs; and, 54 PRACTICE and, when it does, they feem to be thole who happen to be of a robuft habit, to lead an indolent life, and to live very full. CCCCXCVI. The gout attacks efpecially men of robuft and large bodies, men of large heads, of full and corpulent habits, and men whofe {kins are covered with a thicker rete muco- Jumy which gives a coarfer furface. CCCCXCVH. If, with the ancients, we might afcer- tain, by certain terms, the temperaments of men, 1 would fay, that the gout attacks efpe- cially men of a cholerico-fangiiine tempera- ment, and that it very feldom attacks the purely fanguine or melancholic. It is, however, very difficult to treat this matter with due precifion. ccccxcvin. OF PHYSIC. 55 CCCCXCVIII. The gout feldom attacks perfons em- ployed in conftant bodily labour, or per- fons who live much upon vegetable ali- ment. It is alfo faid to be lefs frequent among - thofe people who make no ufe of wine or other fermented liquors. CCCCXCIX. The gout does not commonly attack men, till after the age of five and thirty; and ge- nerally not till a (till later period. There are indeed inftances of the gout occurring more early; but thefe are few in fon of the numbers which agree with what we have given as the general rule* When the difeafe docs appear early in life, it feems to be in thofe in whom the hereditary dif- pofition is very ftrong, and to whom the remote caufes to be hereafter mentioned. have 56 PRACTICE have been applied in a confiderable de- gree. D. As the gout is a hereditary difeafe, and affects efpecially men of a particular habit, its remote caufes may be confidered as predifponent and occafional. DI. The predifponent caufe, fo far as expref- fed by external appearances, or by the ge- neral temperament we have already mark- ed ; and phyficians have been very confi- dent in afligning the occafiona! caufes; but, in a difeafe depending fo much upon a predifpofition, the afligning occafional caufes muft be uncertain; as, in the pre- difpofed, the occafional caufes may not al- ways appear, and in perfons not predif- pofed OF PHYSIC. 57 pofed, they may appear without effect. This uhcertainty muft particularly affect the cafe of the gout; but I lhall offer what appears to me molt probable on the fubjedt. DIE The occafional caufes of the gout feem to be of two kinds. FirR, thofe which induce a plethoric Rate of the body. Se- condly, thofe which, in plethoric habits, induce a Rate of debility. Dill. Of the fir ft kind are a fedentary indolent manner of life, a full diet of animal food, and the large ufe of wine or of other fer- mented liquors. Thefe circumRances com- monly precede the difeafe; and if there fhould be any doubt of their power of Vol. II. E pro« 58 PRACTICE producing it, the fad, however, will be rendered fufficiently probable by what has been obferved in CCCCXCVIII. DIV. Of the fecond kind of occafional caufes which induce debility are, excefs in ve- nery; intemperance in the ufe of intoxi- cating liquors; indigeftion, produced ei- ther by the quantity or quality of aliments; much application to ftudy or bufinefs ; night - watching ; exceffive evacuations; the ceafing of ufual labour; the fudden change from a very full to a very fpare diet; the large ufe of acids and acefcents ; and, laftly, cold applied to the lower ex- tremities. DV. The firft (DHL) feem. to ad by in- creafing O F P H Y S I C. 59 creaflng the predifpofltion. The laft (DIV.) are commonly the exciting caufes, both of the firfl. attacks, and of the repetitions of the difeafe. DVI. It is an inflammatory affection of fome of the joints which efpecially conftitutes what we call a paroxyfm of the gout. This fometimes comes on fuddenly without any warning, but is generally preceded by fe- veral fymptoms; fuch as the ceaflng of a fweating which the feet had been com- monly affected with before; an unufual coldnefs of the feet and legs ; a frequent numbnefs, alternating with a fenfe of prickling along the whole of the lower ex- tremities; frequent cramps of the mufcles of the legs; and an unufual turgcfcence of the veins. E 2 DVII. 60 PRACTICE DVII. While thefe fymptoms take place in the lower extremities, the whole body is af- fecded with fome degree of torpor and lan- guor, and the fundlions of the ftomach in particular are more or lefs difturbed. The appetite is diminiflied, and flatulency, or other fymptoms of indigeftion, are felt. Thefe fymptoms, and thofe of DVI. take place for feveral' days, fometimes for a week or two, before a paroxyfm comes on : but commonly, upon the day imme- diately preceding it, the appetite becomes greater than ufrtal. DVIIL The circumftances of paroxyfms are the following. They come on moft commonly in the fpring, and fooner or later accord- ing. as the vernal heat fucceeds fooner or later OF PHYSIC. 61 later to the winter's cold; and perhaps fooner or later alio according as the body may happen to be more or lefs expofed to vicifiitudes of heat and cold. DIX. The attacks are ibmetimes felt firft in the evening, but more commonly about two or three o'clock of the morning. The paroxyfm begins with a pain affeAing one foot, moft commonly in the ball or firft joint of the great toe, but fometimes in other parts of the foot. With the coming on of this pain, there is commonly more or lefs of a cold fhivering, which, as the pain increafes, gradually ceafes, and is fucceeded by a hot ftage of pyrexia, which continues for the fame time with the pain itfelf. From the firft attack, the pain be- comes by degrees more violent, and con- tinues in this ftate with great reftleflhefs E 3 of 62 PRACTICE of the whole body, till next midnight, after which it gradually remits ; and, after it has continued for twenty-four hours from the commencement of the firft at- tack, it commonly ceafes very entirely, and, with the coming on of a gentle fweat, allows the patient to fall afleep. The patient, upon coming out of this fleep in the morning, finds the pained part affect- ed with fome rednefs and fwelling, which, after having continued for fome days, gradually abate. DX. When a paroxyfm has thus come on, although the violent pain after twenty-four hours be confiderably abated, the patient is not entirely relieved from it. For fome days he has every evening a return of more confiderable pain and pyrexia, and [ which continue with more or lefs violence til! OF PHYSIC. 63 till morning. After continuing in this manner for feveral days, the difeafe fome- times goes entirely off, not to return till after a long interval. DXL When the difeafe, after having thus re- mained for fome time in a joint, ceafes very entirely, it generally leaves the perfon in very perfect health, enjoying greater eafe and alacrity in the fundlions of both body and mind, than he had for a long time before experienced. DXII. At the beginning of the difeafe, the re- turns of it are fometimes only once in three or four years; but, after fome time, the intervals become fliorter, and the attacks become annual ; afterwards they come E 4 twice 64 PRACTICE twice each year, and at length recur fevc- ral times during the whole courfe of au- tumn, winter, and fpring ; and as it hap- pens that, when the fits are frequent, the paroxyfms become alfo longer, fo, in the advanced ftate of the difeafe, the patient is hardly ever tolerably free from it, ex- cept perhaps for two or three months in fummer. DXIII. The progrefs of the difeafe is alfo marked by the parts which it affefts, At firft, it commonly affects one foot only, after- wards every paroxyfm affects both feet, the one after the other; and, as the difeafe continues to recur, it not only affects both feet at once, but after having ceafed in the foot which was fecondly attacked, returns again into the foot ffrft affeeffed, and per- haps a fecond time alfo into the other. Its changes OF PHYSIC. 65 changes of place are not only from one foot to the other, but alfo from the feet into other joints, efpecially thofe of the upper and lower extremities ; fo that there is hardly a joint of the body that is not, on one occafion or other, affected. It fome- times affeCts two different joints at the fame time, but more commonly it is fe- vere in a fingle joint only, and paifes fuc- ceffively from one joint to another; fo that the patient's affliction is often pro- tracted for a long time. DXIV. When the difeafe has often returned, and the paroxyfms have become very fre- quent, the pains are commonly lefs vio- lent than they were at firft ; but the pa- tient is more affected with ficknefs, and the other fymptoms of the atonic gout, which fhall be hereafter mentioned. DXV. 66 PRACTICE DXV. After the firft paroxyfms of the difeafe, the joints which have been affedled arc entirely reftored to their former fupplenefs and ftrength; but after the difeafe has re- curred very often, the joints affefled do neither fo fuddenly nor fo entirely recover their former (late, but continue weak and fliff, and thefe effects at length proceed to fuch a degree ; that the joints lofe their motion altogether. DXVI. In many perfons, but not in all, after the difeafe has frequently recurred, concre- tions of a chalky nature are formed upon the outfide of the joints, and for the moft part immediately under the ikin. The matter feems to be depofited at firft in a fluid form, but afterwards becomes dry and OF PHYSIC. 67 and firm. In their dry ftate, thefe con- cretions are a friable earthy fubftance, very entirely foluble in acids. After they have been formed, they contribute, with other circumftances, to deftroy the motion of the joint. DXVII. In moft perfons who have laboured un- der the gout for many years, a nephritic affection comes on, and difcovers itfelf by all the fymptoms which ufually attend cal- culous concretions in the kidneys, and which we (hall have occalion to defcribe in another place. All that is necelfary to be obferved here is, that the nephritic af- fection alternates with paroxyfms of the gout, and that the two affe&ions, the nephritic and the gouty, are hardly ever prefent at the fame time. This alfo may be obferved, that children of gouty or nephritic 68 PRACTICE nephritic parents, commonly inherit one or other of thefe difeafes; but which ever may have been the principal difeafe of the parent, fome of the children have the one, and fome the other. In. fome of them, the nephritic affection occurs alone, with- out any''gout fupervening; and this hap- pens to be frequently the cafe of thef emale offspring of gouty parents. DXVIII. In the whole of the hiftory already given, I have defcribed the moft common form of the difeafe, and which therefore, however diverlified in the manner I have faid, may be ftill called the regular ftate of the gout. Upon occaiion, however, the difeafe affumes different appearances ; but, as I fuppofe the difeafe to depend always upon a certain diathefis or difpofition of the fyftem; fo every appearance which we can OF PHYSIC. 69 can perceive to depend upon that fame dif- pofition, I ftill conflder as a fymptom and cafe of the gout. The principal circum- ftance in what we term the Regular Gout, is the inflammatory affection of the joints; and, whatever fymptoms we can perceive to be connected with, or to depend upon, the difpofition which produces that inflam- matory affe&ion, but without its taking place, or being prefent at the fame time, we name the Irregular Gout. DXIX. Of fuch irregular gout there are three different ftates, which I name the the and the mifplaced gout. DXX. The atonic ftate is when the gouty dia- thefis prevails in the fyftem, but, from certain 70 PRACTICE certain caufes, does not produce the in- flammatory affedion of the joints. In this cafe, the morbid fymptoms which appear are chiefly affedions of the ftomach; fuch as lofs of appetite, indigeftion, and its various circumftances of ficknefs, naufea, vomiting, flatulency, acid erudations, and pains in the region of the ftomach. Thefe fymptoms are frequently accompanied with pains and cramps in feveral parts of the trunk, and the upper extremities of the body, which are relieved by the difcharge of wind from the ftomach. Together with thefe affections of the ftomach, there commonly occurs a coftivenefs ; but fome- times a loofenefs with colic-pains. Thefe affedions of the alimentary canal are often attended with all the fymptoms of hypo- chondriacs ; as dejedion of mind, a con- ftant and anxious attention to the flighteft feelings, an imaginary aggravation of thefe, and an apprehenfion of danger from them. In OF PHYSIC., 71 In the fame atonic gout, the vifcera of the thorax alfo are fometimes affedled, and palpitations, faintings, and afthma, occur. In the head alfo occur, headachs, gid- dinefs, apopledic and paralytic affections. DXXI. When the feveral fymptoms now men- tioned, occur in habits having the marks of a gouty difpofition, this may be fuf- peCted to have laid the foundation of them; and efpecially when either, in fuch habits, a manifeft tendency to the inflammatory affeCtion has formerly appeared; or when the fymptoms mentioned are intermixed with, and are relieved by, fome degree of the inflammatory gout. In fuch cafes there can be no doubt of confldering the whole as a flate of the gout. DXXII. 72 PRACTICE DXXIL Another ftate of the difeafe I name the retrocedent gout. This occurs when an in- flammatory ftate of the joints has, in the ufual manner, come on, but which, with- out arifing to the ordinary degree of pain and inflammation, or, at leaft, without thefe continuing for the ufual time, and re- ceding gradually in the ufual manner, they fuddenly and entirely ceafe, while fome internal part becomes affected. The in- ternal part moft commonly affedled is the ftomach, which is then affected with an- xiety, flcknefs, vomiting, or violent pain; but fometimes the internal part is the heart, which gives occafion to a fyncope; fometimes it is the lungs which are affect- ed with afthma; and fometimes it is the head, giving occafion to apoplexy or palfy. In all thefe cafes, there can be no doubt of the fymptoms being all a part of the fame OF PHYSIC. 73 fame difeafe, however different the affec- tion may feem to be in the parts which it attacks. dxxiii. The third Rate of irregular gout, which we name the mif is when the gouty diatheiis, inftead of producing the inflam- matory affection of the joints, produces an inflammatory affection of fome internal part, and which appears from the fame fymptoms that attend the inflammation of thofe parts ariflng from other caufes. Whether the gouty diatheiis does ever produce fiich inflammation of the internal parts, without having firft produced it in the joints, or if the inflammation of the internal part be always a tranflation from the joints previoufly affedted, I dare not determine; but, even-fuppoiing the latter to b6 always the cafe, I think the difference Vol. II. F of 74 PRACTICE of the affection of the internal part muft ftill diftinguilh the mifplaced from what I have named the Retrocedent Gout. DXXLV. What internal parts may be affected by the mifplaced gout, I cannot precifely fay, becaufe I have never met with any cafes of the mifplaced gout in my practice; and I find no cafes of it diflinctly marked by practical writers, except that of a pneu- monic inflammation. DXXV. There are two cafes of a tranflated gout; the one of which is an affection of the neck of the bladder, producing pain, ftran- gury, and a catarrhus veflese : The other is an affection of the replum, fometimes by pain alone in that part, and fometimes by 1132- OF PHYSIC* 75 hemorrhoidal fwellings there. In gouty perfons, I have known fuch affections al- ternate with inflammatory affections of the joints: But whether to refer thofe af- fections to the retrocedent, or to the mid- placed gout, I will not prefume to deter- mine* DXXVI. From the hiltory which I have now de- livered of the gout, I think it may be dif- cerned under all its various appearances. It is, however, commonly fuppofed, that there are cafes in which it may be difficult to diftinguiffi gout from rheumatifm, and it is poffible there may be fuch cafes; but, for the moft part, the two difeafes may be diftinguifhed with great certainty by ob- ferving the predifpofition, the antecedents, the parts affedted, the recurrences of the difeafe, and its connexion with the other F 2 parts 76 PRACTICE parts of the fyftem; which circumftances, for the moft part, appear very differently in the two difeafes. DXXVIL With refpedl to the gout, our next bufi- nefs is to inveftigate its proximate caufe; which muft be a difficult talk, and I at* tempt it with fome diffidence. dxxviii. Upon this fubjeft, the opinion which has generally prevailed is, that the gout depends upon a certain morbific matter, always prefent in the body; and that this matter, by certain caufes, thrown upon the joints or other parts, produces the feveral phenomena of the difeafe. DXXIX. OF PHYSIC. 77 DXXIX. This doctrine, however ancient and ge- neral, appears to me very doubtful; for, Firft, there is no direct evidence of any morbific matter being prefent in perfons difpofed to the gout. There are no ex- periments or obfervations which fliow that the blood, or other humours of gouty per- fons, are in any refpecft different from thofe of other perfons. Previous to at- tacks of the gout, there appear no marks of any morbid ftate of the fluids; for the difeafe generally attacks thofe perfons who have enjoyed the molt perfect health, and appear to be in that ftate when the difeafe comes on. At a certain period of the dif- eafe, a peculiar matter indeed appears in gouty perfons, (DXVI.); but this, which does not appear in every inftance, and which appears only after the difeafe has fubfifted for a long time, feems manifeftly F 3 t® 78 PRACTICE to be the effect, not the caufe, of the difeafe, Further, though there be certain acrids which, taken into the body, feein to ex- cite the gout, (DIV.) it is probable that thefe acrids operate otherwife in exciting the difeafe, than by affording the material caufe of it. In general, therefore, there is no proof of any morbific matter being the caufe of the gout. Secondly, The fuppofitions concerning the particular nature of the matter pro- ducing the gout, have been fo various and fo contradictory to each other, as to allow us to conclude, that there is truly no proof of the exiflence of any of them. With refpeCt to many of thefe fuppofitions, they are fo inconfifient with chemical philofo- phy, and with the laws of the animal occo- nomy, that they mull be entirely rejected. Thirdly, The fuppofition of a morbific matter being the caufe of the gout, is not confident with the phenomena of the dif- eafe, OF PHYSIC. 79 eafe, particularly with its frequent and fudden tranflations from one part to an- other. Fourthly, The fuppofition is further ren- dered improbable by this, that, if a mor- bific matter did exift, its operation fhould be fimilar in the feveral parts which it at- tacks ; whereas it feems to be very differ- ent, being ftimulant, and exciting inflam- mation in the joints, but fedative and deftroying the tone in ftomach: Which, upon the fuppofition of particular matter adding in both cafes, is not to be explained by any difference in the part affected. Fifthly, Some facts, alleged in proof of a morbific matter, are not fufliciently con- firmed, fuch as thofe which would prove the difeafe to be contagious. There is, however, no proper evidence of this, the fafts given being not only few, but excep- tionable ; and the negative obfervations are innumerable. F 4 Sixthly, 80 PRACTICE Sixthly, Some arguments brought in favour of a morbific matter, are founded upon a miftaken explanation. The dif- eafe has been fuppofed to depend upon a morbific matter, becaufe it is hereditary. But the inference is not juft ; for moft hereditary difeafes do not depend upon any morbific matter, but upon a parti- cular conformation of the ftrucfture of the body, tranfmitted from the parent to the offspring ; and this laft appears to be par- ticularly the cafe in the gout. It may be alfo obferved, that hereditary difeafes, de- pending upon a morbific matter, always appear much more early in life than the gout commonly does. Seventhly, The fuppofition of a mor- bific matter being the caufe of the gout, has been hitherto ufelefs, as it has not fuggefted any fuccefsful method of cure. Particular fuppofitions have often corrupt- ed the practice, and have frequently led from OF PHYSIC. 81 from thofe views which might be ufeful, and from that practice which experience had approved. Further, though the fup- pofition of a morbific matter has been ge- nerally received, it has been as generally in practice. When the gout has affected the ftomach, nobody thinks of correcting the matter fuppofed to be prefent there, but merely of reftoring the tone of the moving fibres. Eighthly, The fuppofition of a morbific matter is quite fuperfluous; for it ex- plains nothing, without fuppofing that matter to produce a change in the date of the moving powers ; and a change in the ftate of the moving powers, produced by other caufes, explains every circum- ftance, without the fuppofition of a mor- bific matter; and, to this purpofe, it may be obferved, that many of the caufes (DIV.) exciting the gout, do not operate 82 PRACTICE operate upon the ftate of the fluids, but diredlly and folcly upon that of the mo- ving powers. Laftly, The fuppofition of a morbific matter is alfo fuperfluous; becaufe, without any fiich fuppofition, I think the difeafe can be explained in a manner more con- fiftent with its phenomena, with the laws of the animal oeconomy, and with the me- thod of cure which experience has appro- ved. I now proceed to give this explanation ; but, before entering upon it, I muft pre- mife fome general obfervations. DXXX. The firft obfervation is, that the gout is a difeafe of the whole fyftem, or depends upon a certain general conformation and Rate of the body; which manifeftly appears from the fafts mentioned from CCCCXCIV. to OF PHYSIC. 83 to CCCCXCVII. But the general ftate of the fyftem depends chiefly upon the ftate of its primary moving powers; and there- fore the gout may be fuppofed to be chiefly an affection of thefe. DXXXI. My fecond obfervation is, that the gout is manifeftly an affection of the nervous fyftem; in which the primary moving powers of the whole fyftem are lodged. The occasional or exciting caufes (DIV.) are almoft all fuch as act diredlly upon the nerves and nervous fyftem; and the greater part of the fymptoms of the atonic or re- trocedent gout are manifeftly affections of the fame fyftem. (DXX. and DXX1L) This leads us to feek for an explanation of the whole of the difeafe in the laws of the nervous fyftem, and particularly in the changes 84 'PRACTICE changes which may happen in the balanc-c of its feveral parts. DXXXIL My third obfervation is, that the fto- mach, which has fo univerfal a confent with the reft of the fyftem, is the internal part that is the moft frequently, and often very conflderably, afledled by the gout. The paroxyfms of the difeafe are com- monly preceded by an affection of the ftomach (DVII.); many of the exciting caufes (DIV.) act firft upon the ftomach; and the fymptoms of the atonic and re- trocedent gout (DXX. DXXII.) are moft commonly and chiefly affedtions of the fame organ. This obfervation leads us to remark, that there is a balance fub- flfting between the ftate of the internal and that of the external parts; and, in particular, that the ftate of the ftomach is con* O F PHYSIC. 85 Connected with that of the external parts, (XLIV.) fo that the Hate of tone in the one may be communicated to the other. DXXXIIL Thefe obfervations being premifed, I fliall now offer the following pathology of the gout. In fome perfons there is a certain vigo- rous and plethoric Rate of the fyftem. (CCCCXCVI.) which, at a certain period of life, is liable to a lofs of tone in the ex- tremities (CCCCXCIX. DVL). This is in fome meafure communicated to the whole fyftem, but appears more efpecially in the functions of the ftomach (DVIL). When this lofs of tone occurs while the energy of the brain ftill retains its vigour, the visme- dicatrix natural is excited to reftore the tone of the parts ; and accomplifhes it by ex- citing 86 PRACTICE citing an inflammatory affedlion in fome part of the extremities. When this has fub fitted for fome days, the tone of the extremities, and of the whole fyftem, are reftored, and the patient returns to his ordinary flatc of health (DXL). DXXXIV. This is the courfe of things, in the ordi- nary form of the difeafe, which we name the regular gout; but there are circum- ftances of the body, in which this courfe is interrupted or varied. Thus when the atony (DVL DVII.) has taken place, if the re-a&ion (DIX.) do not fucceed, the atony continues in the ftorhach, or perhaps in other internal parts, and pro- duces that (late which we have, for rea- ions now obvious, named the atonic gout. DXXXV. OF PHYSIC. 87 DXXXV. A fecond cafe of variation in the courfe of the gout is, when, to the atony, the re- adlion and inflammation have to a certain degree fucceeded, but, from caufes either internal or external, the tone of the extre- mities, and perhaps of the whole fyftem, is weakened; fo that the inflammatory Rate, before it had either proceeded to the de- gree, or continued for the time, requifite for reftoring the tone of the fyftem, fud- denly and entirely ceafes. Hence the flo- mach, and other internal parts, relapfe into the ftate of atony; and perhaps have this increafed by the atony communicated from the extremities: All which appears in what we have termed the retrocedent gout. DXXXVI. A third cafe of variation from the ordi- nary 88 PRACTICE nary courfe of the gout, is, when, to the atony ufually preceding, an inflammatory re-aclion fully fucceeds : But has its ufual determination to the joints by fome cir- cumftances prevented ; and is therefore di- rected to an internal part, where it pro- duces an inflammatory afteClion, and that ftate of things which we have named the mifplaced gout. DXXXVII We have thus offered an explanation o£ the circumftances of the fyftem in the fe- veral Rates of the gout; and this explanation we fuppofc to be confident with the phe- nomena of the difeafe, and with the laws of the animal oeconomy. There are indeed, with refpedt to the theory of the difeafe, feveral queftions which might be put; to which we have not given any anfwer. But, tho' perhaps we could give an anfwer to many OF PHYSIC. 89 many of thefe queftions, it does not here appear necellary; as at prefent we intend Only to eftablifh fuch general facts with regard to this difeafe, as may lay a founda- tion for the cure of it, fo far as experience has enabled us to profecute it. Proceed- ing, therefore, upon the feveral parts of the pathology given, as fo many matters of fact, I fhall now conlider what may be at- tempted towards the cure of the difeafe. DXXXVIII. In entering upon this, I mull obferve, in the firft place, that a cure has been commonly thought impoflible; and we acknowledge it to be very probable, that the gout, as a difeafe of the whole habit, and very often depending upon original conformation, cannot be cured by medi- cines, the effects of which are always very tranfitory, and feldom extend to Vol. II. G the 90 PRACTICE the producing any coniiderable change of the whole habit. DXXXIX. It would perhaps have been happy for gouty perfons, if this opinion had been implicitly received by them ; as it would have prevented their having been fo often the dupes of felf-intereded pretenders, who have either amufed them with inert medicines, or have raftily employed thofe of the mod pernicious tendency. I am much difpofed to believe the impoffibility of a cure of the gout by medicines; and more certainly dill incline to think, that whatever may be the poffible power of medicines, yet no medicine for curing the gout has hitherto been found. Although almod every age has prcfented a new re- medy, yet all hitherto offered have very foon O F PHYSIC. 91 foon been either negledled as ufelefs, or condemned as pernicious. DXL. Though unwilling to admit the power of medicines, yet I contend, that a great deal can be done towards the cure of the gout by a regimen: And from what has been obferved (CCCCXCVIIL), I am firmly perfuaded, that any man who, early 'in life, will enter upon the confiant practice of bodily labour, and of abfiinence from animal food, will be preferved entirely from the difeafe. Whether there be any other means of radically curing the gout, I am not ready to determine. There are hiftories of cafes of the gout, in which it is faid, that by great emotions of mind, by wounds, and by other accidents, the fymptoms have been fuddenly relieved, and never again G 2 rc- 92 PRACTICE returned; but how far thefe accidental cures might be imitated by art, or would fucceed in other cafes, is at leaft extremely uncertain. DXLI. The practices proper and necefiary in the treatment of the gout, are toconfidered under two heads: As they are to be employed in the intervals of paroxyfms; As during the time of thefe. DXLII. In the intervals of paroxyfms, the indi- cations are, to prevent the return of pa- roxyfins, or at leaft to render them left fre- quent, and more moderate. During the time of paroxyfms, the indications are, to- moderate the violence, and fhorten the du- ration O F P H Y S I C. 93 ration of them as much as can be done with fafety. DXLIII. It has been already obferved, that the gout may be entirely prevented by con- ftant bodily exercife, and by a low diet; and I am of opinion, that this prevention may take place even in perfons who have a he- reditary difpofition to the difeafe. I muft add here, that, even when the difpofition has difcovered itfelf by fever al paroxyfms of inflammatory gout, I am perfuaded that labour and abftinence will abfolutely pre- vent any returns of it for the reft of life. Thefe, therefore, are the means of anfwering the firft indication to be purfued in the in- tervals of paroxyfms; and I muft here offer fome remarks upon the proper ufe of thefe remedies. G 3 DXLIV. 94 PRACTICE DXLIV. Exercife, in perfons difpofed to the gout, is directed to two purpofes: One of thefe is the ftrengthening of the tone of the extreme veffels; and the other, the guarding againfl a plethoric Rate. For the former, if ex- ercife be employed early in life, and before intemperance has weakened the body, a very moderate degree of it will anfwer the purpofe; and for the latter, if abftinence be at the fame time obferved, little exercife. will be neceffary, DXLV. With rcfpccl to cxcrcife, this in general is to be obferved, that it fhould never be violent; for, if violent, it cannot be long continued, and mutt always endanger the bringing on an atony in proportion to the violence of the preceding exercife. DXLVI OF PHYSIC. 95 DXLVI. It is alfo to be obferved, that the exer- cife of geftation, though confiderable and conftant, if it be entirely without bodily exercife, will not anfwer the purpofe in pre- venting the gout. For this end, therefore, the exercife mutt be in feme meafure that of the body ; and muft be moderate, but at the fame time conftant, and continued through life. DXLVII. In every cafe and circumftance of the gout in which the patient retains the ufe of his limbs, bodily exercife, in the in- tervals of paroxyfms, will always be ufe- ful; and, in the beginnings of the difeafe, when the difpofition to it is not yet ftrong, exercife may prevent a paroxyfm which otherwife might have come on. In more G 4 advanced 96 PRACTICE advanced flates of the difeafe, however, when there is fome difpofition to a pa- roxyfm, much walking will bring it on ; either as it weakens the tone of the lower extremities, or as it excites an inflamma- tory difpofition in them; and it is pro- bable, that in the fame manner ftrains or contufions often bring on a paroxyfm of the gout. DXLVIII. Abftinence, the other part of our regi- men (DXL.) for preventing the gout, is of more difficult application. If an abfti- nence from animal-food be entered upon early in life, while the vigour of the fy- Item is yet entire, we have no doubt of its being both fafe and effectual; but, if the motive for this dietffiall not have occur- red till the conftitution ffiall have been broken by intemperance, or by the de- cline OF PHYSIC. 97 cline of life, a low diet may then endanger the bringing on an atonic ftate. DXLIX. Further, if a low diet be entered upon only in the decline of life, and be at the fame time a very great change in the for- mer manner of living, the withdrawing of an accuftomed ftimulus of the fyftem may readily throw this into an atonic ftate. DL. The fafety of an abftemious courfe may be greater or lefs according to the manage- ment of it. It is animal-food which es- pecially difpofes to the plethoric and in- flammatory ftate, and that food is to be therefore efpecially avoided; but, on the other hand, it is vegetable aliment of the loweft quality that is in danger of weak- ening 98 PRACTICE ening the fyftem too much, by not afford- ing fufficient nourifhment; and more par- ticularly, of weakening the tone of the ftomach by its acefcency. It is therefore a diet of a middle nature that is to be chofen ; and milk is precifely of this kind, as containing both animal and vegetable matter. As approaching to the nature of milk, and as being a vegetable matter contain- ing the greateft portion of nourifhment, the farinaceous feeds are next to be chofen and are the food moft proper to be joined with milk. DLL With refpedl to drink, fermented liquors are ufeful only when they are joined with animal-food, and that by their acefcency; and their ftimulus is only neceflary from cuftom. When, therefore, animal-food is to OF PHYSIC. 99 to be avoided, fermented liquors are un- neceffary; and, by increafing the acefcency of vegetables, thefe liquors may be hurt- ful. The ftimulus of fermented or fpi- rituous liquors, is not neceffary to the young and vigorous; and, when much employed, impairs the tone of the fyftem, Thefe liquors, therefore, are to be avoided, except fo far as cuftom and the declining Hate of the fyftem may have rendered them neceffary. For preventing or mode- rating the regular gout, water is the only proper drink. DLII. With refpedl to an abflemious courfe, it has been fuppofed, that an abftinence from animal-food and fermented liquors, or the living upon milk and farinacea alone for the fpace of one year, might be fuffi- cient for a radical cure of the gout: and it 100 PRACTICE it is poflible that, at a certain period of life, in certain circumftances of the con- ftitution, fuch a meafure might anfwer the purpofe. But this is very doubtful; and it is more probable that the abftinence muft, in a great meafure, be continued, and the milk diet be perliiled in, for the reft of life. It is well known, that feveral perfons who had entered on an abflemious courfe, and had been thereby delivered from the gout, have, however, upon re- turning to their former manner of full Jiving, had the difeafe return upon them with as much violence as before, or in a more irregular and more dangerous form. DLIII. It has been alleged, that, for prevent- ing the return of the gout, blood-letting, or fcarifications of the feet, frequently re* peated, and at ftated times, may be prac- tifed OF PHYSIC. 101 tifed with advantage; but of this I have had no experience. DLIV. Exercife and abftinence are the means of avoiding the plethoric ftate which gives the difpofition to the gout, and are therefore the means propofed for preventing paro- xyfms, or at leaft for rendering them lefs frequent, and more moderate. But many circumftandes prevent the fteadinefs ne« ceflary in purfuing thefe meafures; and therefore, in fuch cafes, unlefs great care be taken to avoid the exciting caufes, the difeafe may frequently return; and, in many cafes, the preventing of paroxyfms is chiefly to be obtained by avoiding thofe exciting caufes enumerated in DIV. The conduct neceflary for avoiding them, will be fufliciently obvious to perfons acquaint- ed with the doctrines of the Hygieine, which PRACTICE 102 which I fuppofe to have been delivered in another place. DLV. A due attention in avoiding thofe feveral caufes, (Dill, DIV.) will certainly pre- vent fits of the gout; and the taking care that the exciting caufes be never ap- plied in a great degree, will certainly ren- der fits more moderate when they do come on. But, upon the whole, it will appear, that a ftridt attention to the whole con- duct of life, is in this matter necelfary; and therefore, when the predifpofition has taken place, it will be extremely difficult to avoid the difeafe. DLVI. I am indeed firmly perfuaded, that, by obviating the predifpofition, and by avoid- ing OF PHYSIC. 103 ing the exciting caufes, the gout may be entirely prevented: But as the meafures neceiTary for this purpofe will, in moft Cafe's, be purfued with difficulty, and even with reluctance, men have been very de- firous to find a medicine which might an- fwer the purpofe without any reftraint on their manner of living. To gratify this defire, phyficians have propofed, and, to take advantage of it, empirics have feigned, many remedies, as we have already ob- ferved. Of what nature feveral of thefe remedies have been, I cannot certainly fay; but, of thofe which are unknown, we con- clude, from their having been only of temporary fame, and from their having focn fallen into neglect, that they have been either inert or pernicious, and there- fore I make no inquiry after them; and lhall now remark only upon one or two known remedies for the gout which have been lately in vogue. DLVIL 104 PRACTICE DLVII. One of thefe is what has been named in England the Portland Powder. This is not a new medicine, but is mentioned by Galen, and, with fome little variation in its compofition, has been mentioned by the writers of almoft every age fince that time. It appears to have been at times in fafhion, and to have again fallen into neg- left ; and I think that this laft has been owing to its having been fourtd to be, in many inftances, pernicious. In every in- ftance which I have known of its exhibi- tion for the length of time prefcribed, the perfons who had taken it were indeed afterwards free from any inflammatory afleftion of the joints : but they were af- fefted with many fymptoms of the atonic gout; and all, foon after finifliing their courfe of the medicine, have been attacked with OF PHYSIC. 105 With apoplexy, afthma, or dropfy, which proved fatal. DLVIII. Another remedy which has had the ap- pearance of preventing the gout, is an al- kali in various forms, fuch as the fixed alkali both mild and cauftic, lime-water, foap, and ab forbent earths. Since it be- came common to exhibit thefe medicines in nephritic and calculous cafes, it has often happened that they were given to thofe who were at the fame time fubjedl to the gout; and it has been obferved* that, under the ufe of thefe medicines, gouty ptrfons have been longer free from the fits of their difeafe. That, however, the ufe of thefe medicines has entirely prevented the returns of gout, I do not know ; becaufe I never puflied the ufe of thofe medicines for a long time, being apprehenfive that the long continued ufe Vol. II. H of 106 PRACTICE of'them might produce a hurtful change in the ftate of the fluids. DLIX. With refpeft to preventing the gout, I have only one other remark to offer. As the preventing the gout depends very much on fupporting the tone of the ftomach, and avoiding indigeftion ; fo coflivenefs, by eccafioning this, is very hurtful to gouty perfons. It is therefore neceffary for fuch perfons to prevent or remove coflivenefs, and, by a laxative medicine, when need- ful; but it is at the fame time proper, that the medicine employed fhould be fuch as may keep the belly regular, without much purging. Aloetics, rhubarb, magnefia alba, or flowers of fulphur, may be em- ployed, as the one or the other may hap- pen to be beft fuited to particular perfons. DLX. OF PHYSIC. 107 DLX. Thefe are the feveral meafures (from DXLII. to DLIX.) to be purfued in the intervals of the paroxyfms; and we are next to mention the meafures proper du- ring the time of them. DLXI. As during the times of paroxyfms the body is in a feverifh ftate, no irritation fhould then be added to it; and every part, therefore, of the antiphlogiftic regimen, (CXXX. to CXXXIII.) except the appli- cation of cold, ought to be ftridlly ob- ferved. Another exception to the general rule may occur when the tone of the ftomach is weak, and when the patient has been before much accuftomed to the ufe of ftrong drink; for then it may be allowable, H 2 and 108 PRACTICE and even neceflary, to give forne animal- food, and a little wine. DLXII. That no irritation is to be added to the fyftem during the paroxyfms of gout, ex- cept in the cafes mentioned, is entirely agreed upon among phyficians : But it is a more difficult matter to determine whe- ther, during the time of paroxyfms, any meafures may be purfued to moderate the violence of readlion and of inflammation. Dr Sydenham has given it as his opinion, that the more violent the inflammation and pain, the paroxyfms will be the {hot- ter, as well as the interval between the prefent and next paroxyfm longer: and, if this opinion be admitted as juft, it will forbid the ufe of any remedies which might moderate the inflammation; which is, to a certain degree, undoubtedly ne- ceflary OF PHYSIC. 109 ceffary for the health of the body. On the other hand, acute pain prefles for re- lief, and, although a certain degree of in- flammation may feem abfolutely neceflary, it is not certain but that a moderate degree of it may anfwer the purpofe: And it is even probable, that, in many cafes, the violence of inflammation may weaken the tone of the parts, and thereby invite a re- turn of paroxyfms. It feems to me to be in this way, that, as the difeafe advances, the paroxyfms become more frequent. DLXIIL From thefe laft confiderations, it feems probable, that, during the time of paro- xyfins, feme meafures may be taken to moderate the violence of the inflammation and pain ; and particularly, that in firfl: paroxyfms, and in the young and vigo- rous, blood-letting at the arm may be prac- tifed H 3 110 PRACTICE tifed with advantage: But I am perfuaded, that this practice cannot be repeated often with fafety; becaufe blood-letting not only weakens the tone of the fyflem, but may alfo contribute to produce plethora. I be- lieve, however, that bleeding by leeches on the foot, and upon the inflamed part, may be pradlifed, and repeated with greater fafety; and I have known inftances of its having been pracffifed with fafety, to mo- derate and fhorten paroxyfms : but how far it may be carried, we have not had experience enough to determine. DLXIV. Befides blood-letting, and the antiphlo- giflic regimen, it has been propofed to employ remedies for moderating the in- flammatory fpafm of the part affected, fuch as warm bathing, and emollient poultices. Thefe have fometimes been employed with advantage OF PHYSIC. 111 advantage and fafety; but, at other times, have been found to give occafion to a re- troceflion of the gout. DLXV. Bliftering is a very effectual means of relieving and difcufling a paroxyfm of the gout; but has alfo frequently had the ef- fect of rendering it retrocedent. DLXVI. The flinging with nettles I confider as analogous to bliftering; and I think it probable that it would be attended with the fame danger. DLXVII. The burning with moxa, or other fub- flances, I confider as a remedy of the fame H 4 kind, 112 PRACTICE kind. I have had indeed no evidence of this proving hurtful; but neither have I had any proper evidence of its having pro- ved a radical cure. DLXVIII. Camphire, and fome aromatic oils, have the power of allaying the pain, and of removing the inflammation from the part affeded: but thefe remedies com- monly make the inflammation only fliift from one part to another, and therefore with the hazard of its falling upon a part where it may be more dangerous; and they have fometimes rendered the gout retro- cedent. DLXIX. From thefe refledions (DLXIV. et feq.) it will appear, that feme danger muft at- tend OF PHYSIC. 113 tend every external application to the parts afledled, during a paroxyfm; and that therefore the common practice of commit- ting the perfon to patience and flannel alone, is eftablifhed upon the belt foum dation. DLXX. Opiates give the moft certain relief from pain; but, when given in the beginning of gouty paroxyfms, occafion thefe to re- turn with greater violence. When, how- ever, the paroxyfms fliall have abated in their violence, but ftill continue to return, fo as to occafion painful and reftlefs nights, opiates may be then given with fafety and advantage, efpecially in the cafe of perfons advanced in life, and who have been often affected with the difeafe. DLXXI. 114 PRACTICE DLXXL When, after paroxyfms have ceafed, fome fwelling and ftiffnefs fhall remain in the joints, thefe fymptoms are to be dif* cuffed by the diligent ufe of the flefh-brufh. DLXXII. Purging, immediately after a paroxyfm, will be always employed with the hazard of bringing it on again. DLXXIIL I have now finifhed what has occurred to be laid upon the means of preventing and curing the regular gout; and fhall now confider its management when it has become irregular, of which, as I have ob- ferved above, there are three different cafes. DLXXIV. OF PHYSIC. 115 DLXXIV. In the firft cafe, which I have named the Atonic Gout, the cure is to be accom- plifhed by carefully avoiding all debili- tating caufes; and by employing, at the fame time, the means of ftrengthening the fyftem in general, ancj the ftomach in par- ticular. DLXXV. For the avoiding debilitating caufes, I muft refer to the dodlrines of the Hygi- enic, as in DLIV. DLXXVI. For ftrengthening the fyftem in gene- ral, I muft recommend frequent exercife on horfeback, and moderate walking. Cold bathing alfo may anfwer the purpofe, and may 116 PRACTICE may bp fafely employed, if it appear to be powerful in ftimulating the fyftem, and be not applied when the extremities are threat- ened with any pain. For fupporting the tone of the fyftem in general, when threatened with atonicg out, fome animal food ought to be employed, and the more acefcent vegetables ought to be avoided. In the fame cafe, fome wine alfo may be neceifary; but it Ihould be in moderate quantity, and of the leaft acefcent kinds; and, if every kind of wine fhall be found to increafe the acidity of the fto- mach, ardent fpirits and water muft be employed. DLXXVII. For ftrengthening the ftomach, bitters and the Peruvian bark may be employed ; but care muft be taken that they be not con* OF PHYSIC. 117 conftantly employed for any great length of time. Compare DLVII. I The moft effectual medicine for ftrength- ening the ftomach is iron, which may be employed under various preparations; but, to me, the beft appears to be the ruft in fine powder, which may be given in very large dofes. For fupporting the tone of the ftomach, aromatics may be employed ; but fliould be ufed with caution, as the frequent and large ufe of them may have an oppofite ef- fect; and they fliould therefore be given only in compliance with former habits, or for palliating prefent fymptoms. When the ftomach happens to be liable to indigeftion, gentle vomits may be fre- quently given; and proper laxatives fliould be always employed to obviate, or to re- move, coftivenefs. DLXXVIII. 118 PRACTICE DLXXVIII. In the atonic gout, or in perfons liable to it, to guard againft *cold is efpecially necelfary; and the mod certain means of doing this, is by repairing to a warm cli- mate during the winter-feafon. DLXXIX. In the more violent cafes of the atonic gout, bliftering the lower extremities may- be ufeful; but that remedy fhould be avoided when any pain threatens the ex- tremities. In perfons liable to the atonic gout, iflues may be eftablifhed in the ex- tremities, as, in fome meafure, a fupple- ment to the difeafe. DLXXXrf A fecond cafe of the irregular gout, is that OF PHYSIC. 119 that which I have named the Retrocedent. When this affects the ftomach and inte- ftines, relief is to be inftantly attempted by the free ufe of ftrong wines, joined with aromatics, and given warm; or if thefe fliall not prove powerful enough, ardent fpi- rits mull be employed, and are to be given in a large dofe. In moderate attacks, ardent fpirits impregnated with garlic, or with afa foetida, may be employed; or, even without the ardent fpirits, afolution of afa foetida with the volatile alkali may anfwer the purpofe. Opiates are often an effec- tual remedy, and may be joined with aro- matics, as in the Electuarium Thebaicum; or they may be ufefally joined with volatile alkali and camphire. Mufk has likewife proved ufeful in this difeafe. When the affection of the ftomach is accompanied with vomiting, this may be encouraged, by taking draughts of warm wine, at firft with water, and afterwards with- 120 PRACTICE without it; having at length recourfe, if necellary, to feme of the remedies above mentioned, and particularly the opiates. In like manner, if the inteftines be af- fected with diarrhoea, this is to be at firft encouraged, by taking plentifully of weak broth ; and when this lhall have been done fufficiently4 the tumult is to quieted by opiates. DLXXXI. When the retrocedent gout fhall affect the lungs, and produce afthma, this is to be cured by opiates, by antifpafmodics, and, perhaps, by buffering on the breaft or back. DLXXXII. When the gout, leaving the extremities, fliall afteft the head and produce pain, vertigo. OF PHYSIC. 121 vertigo, apoplexy, cr palfy, our refourccsare very precarious. The moft probable means of relief is, bliflering the head; and if the gout fliall have receded very entirely from the extremities, blifters may be applied to thefe alfo. Together with thefe blifterings, aromatics, and the volatile alkali, may be thrown into the ftomach. DLXXXIII. The third cafe of the irregular gout is what I have named the Mifplaced, that is, when the inflammatory affection of the gout, inftead of falling upon tire extremities, falls upon fome internal part. In this cafe, the difeafe is to be treated by blood-letting, and by fuch other remedies as would be proper in an idiopathic inflammation of the fame parts. Vol. II. I DLXXX1V. 122 PRACTICE DLXXX1V. "Whether the tranflation fo frequently made from the extremities to the kidneys, is to be confidered as an inftance of the mifplaced gout, feems, as we have faid be- fore, uncertain: but I am difpofed to think it fomething different; and therefore am of opinion, that, in the Nephralgia Calculofa produced upon this occafion, the remedies of inflammation are to be employed no farther than they may be otherwife fome- times neceffary in that difeafe, arifing from other caufes than the gout. BOOK BOOK HI. Of EXANTHEMATA, or ERUPTIVE FEVERS. DLXXXV. THE difeafes comprehended under this title, which make the third Order of Pyrexiae in our Nofology, are in general fuch as do not arife but upon occafion of a fpecific contagion applied, which firft produces fever, and afterwards an eruption upon the furface of the body; and which dif- I 2 124 PRACTICE difeafes, for the moft part, affect perfons but once in the courfe of their lives. DLXXXVJ. Whether the character of the Order may be thus limited, or if the Order may be allowed to comprehend alfo the eruptive fevers produced by a matter generated in the body itfelf, and likewife thofe cafes of eruption which do not depend .upon con- tagion, or upon a matter generated before the fever, but upon a matter generated in the courfe of the fever, I am not ready to determine. Of the difeafes enumerated by the Nofologifls as Exanthemata. there are certainly three different kinds, which may be diftinguiflied by the circum fiances mentioned in this and the preceding para- graph. Of the firfl kind are the Small-pox, the Chicken-pox, the Meafles, the Scarlet Fever, and the Plague. Of the fecond kind fcems 'OF PHYSIC. 125 feems to be the Eryfipelas; and of the third kind I judge the Miliaria and Pe- techia to be. But as I am not fufficiently confident in the facts which fhould fupport thefe diftindlions, or which would enable us to apply them in all cafes; I go on in this book to treat of almoft all the exanthe- mata enumerated by preceding Nofologifts, with only fome difference in the arrange- ment from what it was in my former edi- tions. I 3 CHAP. 126 PRACTICE CHAP. I. Of the Sm a ll-pox. DLXXXVII. THE fmall-pox is a difeafe ariiingfrom a contagion of a ipecific nature, which firft produces a fever, and, on the third or fourth day thereof, produces an eruption of fmall red pimples. Thefe are afterwards formed into puftles, containing a matter, which, in the courfe of eight days from the time of the eruption, is changed OF PHYSIC. 127 changed into pus. After this, the matter dries, and falls off in crufts. DLXXXVIIL This is a general idea of the difeafe; but there are two particular forms or va- rieties of it, well known under the appel- lations of the Di/linfl and which require to be ipecially defcribed. DLXXXIX. In the former, or the diftincft fmall-pox, the eruptive fever is moderate, and ap- pears to be evidently of the inflammatory kind, or what we name a Synocha. It ge- nerally comes on about mid-day, with fome fymptoms of a cold ftage, and commonly with a confiderable languor and drowfinefs. A hot ftage is foon formed, and becomes more confiderable on I 4 the 128 PRACTICE the fecond and third days. During this courfe, children are liable to frequent Hart- ings from their {lumbers; and adults, if they are kept a-bed, are difpofcd to much fweating. On the third day, children are fometimes affedted with one or two epi- leptic fits. Towards the end of the third day, the eruption commonly appears, and gradually increafes during the fourth; ap- pearing firft upon the face, and fuccefiively on the inferior parts, fo as to be completed over the whole body on the fifth day. From the third day, the fever abates; and againft the fifth, it entirely ceafes. The eruption appears firft in fmall red fpots, hard- ly eminent, but by degrees rifing into pim- ples. Thefe are generally upon the face in fmallnumber; but, even when more nume- rous, they arc feparate and diftindt from one another. On the fifth or fixth day, a fmall veficle, containing an almofl colourlefs or whey-coloured fluid, appears upon the top o OF PHYSIC. 129 of each pimple. For two days, thefe ve- licles increafe in breadth only, and there is a fmall hollow pit in their middle; fo that it is only againft the eighth day that they are raifed into fpheroidical puftules. Thefe veficles or puftules, from their firft formation, continue to be furrounded with an exactly circular inflamed margin, which, when the puftules are numerous, diffufes fome inflammation over the neigh- bouring ficin, fo as to give fomewhat of a damafk rofe colour to the fpaces between the puftules. As the puftules increafe in fize, if they be numerous on the face, againft the eighth day the whole of the face becomes confiderably fwelled; and, in particular, the eye-lids are fo much fwelled as entirely to fhut the eyes. As the difeafe thus proceeds, the matter in the puftules becomes by degrees more opaque and white, and at length of a yel- lowifh colour. On the eleventh day, the fwelling 130 PRACTICE fwelling of the face is abated, and tlid puftules feem quite full. On the top of each a darker fpot appears; and at this place the puftule, on the eleventh day, or foon after, is fpontaneoufly broken, and a portion of the matter oozes out; in confe- quence of which, the puftule is fhrivelled, and fubfides; while the matter oozing out dries, and forms a cruft upon its furface* Sometimes a little only of the matter oozes out; and what remains in the puftule be- CQmes thick, and even hard. After fome days, both the crufts and the hardened puftules fall off, leaving the ikin which they covered of a brown red colour; and it is only after many days that the ikin in thefe places refumes its natural colour. In fome cafes, where the matter of the pu- ftules has been more liquid, the crufts formed by it are later infalling off, and the part they covered fuffers fome defquama- tion, which leaves in it a fmall pit or hollow. This OF PHYSIC. 131 This is the courfe of things on the face; and fucceflively, the puftules on the reft of the body take the fame. The matter of the puftules, on the arms and hands, is frequently abforbed; fo that, at the height of the difeafe, thefe puftules appear as empty veficles. On the tenth and ele- venth days, as the fwelling of the face fub- iides, a fwelling arifes in the hands and feet; but which, again, fubiides, as the puftules come to maturity. When the puftules on the face are nu- merous, fome degree of pyrexia appears on the tenth and eleventh days, but difappears again after the puftules are fully ripened; or perhaps remains in a very flight degree till the puftules on the feet have finifhed their courfe. It is feldom that in the diftincft fmall-pox the fever continues longer. When the puftules on the face are nu- merous, fome uneafinefs in the throat, with a 132 TRACTICE a hoarfcnefs of the voice, comes on upon the iixth or feventh day, and a thin liquid is poured out from the mouth Thefe fymptoms increafe with the fwelling of the face ; and the liquids of the mouth and throat becoming thicker, are more difficultly thrown out. There is, at the fame time, fome difficulty of fwallowing; fo that liquids taken in to be fwallowed are frequently rejected, or thrown out by the nofe. But all thefe affedlions of the fauces abate as the fwelling of the face fubfides. DXC. In the other form of fmall-pox, or what is called the Confluent, the courfe of the difeafe is, in general, the fame with that we have defcribed; but the fymptoms of every ftage are more violent, and feveral of the circumftances are different. In OF PHYSIC. 133 In particular, the eruptive fever is more violent. The pulfe is more frequent and more contradied, approaching to that flate of pulfe which is found in the typhus. The coma is more conliderable, and there is frequently a delirium. Vomiting, alfo, is a common fymptom, efpecially at the coming on of the difeafe. In very young infants, epileptic fits are fometimes fre- quent on the firft days of the difeafe, and fometimes prove fatal before any eruption appears; or they ulher in a very confluent and putrid fmall-pox. DXCI. The eruption appears more early on the third day, and it is frequently preceded or accompanied with an eryfipelatous efflo- refcence. Sometimes the eruption appears in clufters, like that of the mealies. When the eruption is completed, the pimples are always 134 PRACTICE always more numerous upon the face, and at the fame time fmaller and lefs eminent. After the eruption, the fever fuffers fome remiffion, but never goes off entirely; and, after the fifth or fixth day, it again in- creafes, and continues confiderable through the remaining courfe of the difeafe. The vcficles formed on the tops of the pimples appear fooner; and while they in- creafe in breadth, do not retain a circular, but are every way of an irregular figure. Many of them run into one another, info- much that very often the face is covered ra- ther with one veficle than with a number of puftules. The veficles, fo far as they are any ways feparated, do not arife to a fphe- roidical form, but remain flat, and fome- times the whole of the face is of an even furface When the puftules are in any meafure feparated, their circumference is not bounded by an inflamed margin, and the OF PHYSIC. 135 the part of the fkin that is free from puf- tules is commonly pale and flaccid. The liquor that is in the puftules changes from a clear to an opaque appearance, and becomes whitilh or brownifli, but never acquires the yellow colour and thick con»- fiftence that appear in the diftintft fmall- pox. DXCII. The fwelling of the face which attends the diftindl fmall-pox, when they are numerous, and almoft then only, always attends the confluent, comes on more early, and arifes to a greater degree; but abates on the tenth day, and on the eleventh ftill more. At this time the puftules or ve- ficles break, and fhrivelling pour out a li- quor that is formed into brown or black crufts, which do not fall off for many days Thofc of the face, in falling off, leave 136 PRACTICE leave the parts they cover fubjecl to a de- fquamation, which pretty certainly pro- duces pittings. On the other parts of the body, the puftules of the confluent fmall-pox are more diftincl than upon the face, but ne- ver acquire the fame maturity and conflu- ence of pus as in the properly diftindt kind. • The falivation which, only fometimes, attends the diftindl fmall-pox, very con- stantly attends the confluent; and both the falivation and the afl'eclion of the fauces above-mentioned, are, efpecially in adults, in a higher degree. In infants, a diar- rhoea comes frequently in place of the fa- livation. In the confluent fmall-pox, there is of- ten a confidcrable putrefcency of the fluids, as appears from petechise, from ferous ve- ficles, under which the fkin fliows a dif- pofition to gangrene, and from bloody urine O F P H Y S I C. 137 urine or other all which fymptoms frequently accompany this dif- eafe. In the confluent fmall-pox, the fever, which had only fuffered a remiflion from the time of eruption to that of maturation, is often, at or immediately after this pe- riod, renewed with confiderable violence. This is what has been called the Secondary Fever; and is, in different cafes, of various duration and event. DXCI1I. We have thus endeavoured to defcribe the various circumftances of the fmall- pox ; and from the difference of thefe cir- cumftances, the event of the difeafe may- be determined. The whole of the prog- nofis may be nearly comprifed in the fol- lowing proportions. The more exactly the difeafe retains the Vol. II. K form 138 PRACTICE form of the diftinft kind, it is the fafer; and the more completely the difeafe takes the form of the confluent kind, it is the more dangerous. It is only when the diftinft kind fhows a great number of puftules on the face, or otherwife, by fever or putrefcency, ap- proaches to the circumftances of the con- fluent, that it is attended with any danger. In the confluent fmall-pox there is al- ways danger; and this is always more confiderable and certain, according as the fever is more violent and permanent, and efpecially as the marks and fymptoms of putrefcency are more evident. When the putrid difpofltion is very great, the difeafe fometimes proves fatal before the eighth day ; but in moft cafes it is on the eleventh that death happens, and fometimes it is put ofF till the fourteenth or feventeenth day. Though the fmall-pox fhould not be mime- OF PHYSIC. 139 immediately fatal, the more violent kinds are often followed by a morbid ftate of the body, of various kind and event. Thefe confequences, as I judge, may be imputed fometimes to an acrid matter produced by the preceding difeafe, and depofited in dif- ferent parts; and fometimes to an inflam- matory diathefis produced, and determined to particular parts of the body. DXC1V. It is, I think, agreed among practi- tioners, that, in the different cafes of fmall- pox, the difference chiefly depends upon the appearance of diflindl or confluent; and, from the above defcription of thefe kinds, it will appear, that they chiefly differ in the period of the eruption, in the number of puflules produced, in the form of the puflules, in the flate of the matter contained in them, in the continuance of K 2 the PRACTICE 140 the fever, and laftly in the danger of the difeafe. DXCV. Upon inquiring into the caufes of thefe differences, we might readily fufpccl, that they depended upon a difference of the contagion producing the difeafe. This, however, is not probable: for there are innumerable inftances of the contagion, arifing from a perfon labouring under the fmall-pox of the diftindl kind, producing the confluent ; and, on the contrary. Since the practice of inoculation became frequent, we have known the fame vario- lous matter produce in one perfon the di- flinct, and in another the confluent fmall- pox. It is therefore highly probable, that the difference of the fmall-pox does not depend upon any difference of the conta- gion, but upon fome difference in the ftate OF PHYSIC. 141 ftate of the perfons to whom it is applied, or in the ftate of certain circumftances concurring with the application of the contagion. DXCVI. To find out wherein the difference in the ftate of the perfons to whom the con- tagion of the fmall-pox is applied confifts, I obferve, that the difference between the diftintft and confluent fmall-pox confifts efpecially in the number of puftules pro- duced ; which, in the diftintft, are generally few ; in the confluent, always many. If, therefore, we fliall be able to difcover what, in the ftate of different perfons, can give occafion to more or fewer puftules, we Ihall probably be able to account for all the other differences of the diftindl and confluent fmall-pox. K3 DXCVIL 142 PRACTICE DXCVIL It is evident, that the contagion of the fmall-pox is a ferment with refpedt to the human fluids, and affimilates a great part of them to its own nature; and it is pro- bable, that the quantity thus afhmilated, is, in proportion to the bulk of their feve- ral bodies, nearly the fame in different perfons. This quantity paffes again out of the body, partly by infenfible perfpira- tion, and partly by being depofited in puftules; but'if the quantities generated be nearly equal, the quantities palling out of the body by the two ways mentioned are very unequal in different perfons; and, therefore, if we can explain the caufes which determine more to pafs by the one way than by the other, we may thereby difcover the caufes wrhich give occafion to more puftules in one perlon than in ano- ther. DXCVIII. OF PHYSIC. 143 DXCVIII. The caufes which determine more of the variolous matter to pafs by perfpiration, or to form puftules, are probably certain circumftances of the fkin, that determine more or lefs of the variolous matter to flick in it, or to pafs freely through it. DXCIX. The circumftance of the fkin, which feems to determine the variolous matter to flick in it, is a certain ftate of inflamma- tion, depending much upon the heat of it: Thus we have many inftances of parts of the body, from being more heated, having a greater number of puftules than other parts. In the prefent practice of inoculation, in which few puftules arc produced, much feems to be owing to the care that is taken to keep the fkin cool. Parts covered with K 4 plafters, 144 PRACTICE plafters, efpecially with thofe of a ftimulant kind, have more puftules than other parts. Further, certain circumftances, fuch as adult age, and full living, determining to a phlogiftic diathefis, feem to produce a greater number of puftules ; while the contrary circumftances have contrary ef- fects. DC. It is therefore probable, that an inflam- matory ftate of the whole fyftem, and more particularly of the fkin, gives occa- iion to agreater number of puftules: and the caufes of this may likewife produce moft of the other circumftances of the confluent fmall-pox; fuch as the period of eruption; the continuance of the fever; the eflufion of a more putrefcent matter, and lefs fit to be converted into pus; and, what arifes from O F PHYSIC. 145 from thence, the form and other circum- ftances of the puflules. DCI. Having thus attempted to account for the chief difference which occurs in the hate of the fmall-pox, we fhall now try the truth of our dodtrine, by its applica- tion to practice. DCII. In confidering the practice, we view it firft, in general, as fuited to render the difeafe more generally benign and fafe, and this by the practice of inoculation. DCIII. It is not neceffary here to defcribe the operation of inoculating; and what we name 146 PRACTICE name the practice of inoculation, compre- hends all the feveral meafures which pre- cede or follow that operation, and are fup- pofed to produce its falutary effects. Thefe meafures are chiefly the follow- ing. 1. The choofing for the fubjecl of ino- culation perfons otherwife free from dif- eafe, and not liable, from their age or other circumftances, to any incidental dif- eafe. 2. The choofing a perfon at the time of life moft favourable to a mild difeafe. 3. The choofing for the practice a fea- fon the moft conducive to the mildnefs of the difeafe. 4. The preparing the perfon to be ino- culated, by abftinence from animal-food for fome time before inoculation. 5. The preparing the perfon by courfes of mercurial and antimonial medicines. 6. The taking care, at the time of ino- culation, OF PHYSIC. 147 culation, to avoid cold, intemperance, fear or other circumftances which might ag- gravate the future difeafe. 7. After thefe preparations and precau- tions, the chooling a fit matter to be em- ployed in inoculation, by taking it from a perfon of a found conftitution, and free from any difeafe or fufpicion of it; by taking it from a perfon who has had the fmall-pox of the mod benign kind; and, laftly, by taking the matter from fuch per- fons, as foon as it has appeared in the pudules, either in the part inoculated, or on other parts of the body. 8. The introducing, by inoculation, but a fmall portion of the contagious matter. 9. After inoculation, the continuing the vegetable diet, as well as the employment of mercurial and antimonial medicines; and, at the fame time, frequently employ- ing purgatives. io. Both 148 PRACTICE 10. Both before and after inoculation, taking care to avoid external heat, either from the fun, artificial fires, warm cham- bers, much clothing, or being much in bed; and, on the contrary, expofing the perfon to a free and cool air. 11. Upon the appearance of the eruptive fever, the rendering that moderate by the employment of purgatives ; by the ufe of cooling and antifeptic acids; and efpe- cially, by expofing the perfon frequently to a cool and even a cold air, at the fame time giving freely of cold drink. 12. After the eruption, the continuing the application of cold air, and the ufe of purgatives, during the courfe of the dif- eafe, till the puftules are fully ripened. DCIV. Thefe are the meafures propofed and practifed in the lateft and moft improved ftate OF PHYSIC. 149 Hate of inoculation ; and the advantages obtained by the whole of the practice, or at leaft by molt of the meafures above- mentioned, are now afcertained by a long experience to amount to this, That, in in ninety-nine cafes of the hundred, ino- culation gives a diftind: fmall-pox only, and that alfo very generally of the mildeft form: but it will ftill be ufeful, for the proper conduct of inoculation, to confider the importance and utility of the feveral meafures above-mentioned, that we may thereby more exactly determine upon what the advantages of inoculation more cer- tainly depend. DCV, As the common infection may often feize perfons labouring under another dif- eafe, which may render the fmall-pox more violent, it is obvious that inoculation muft 150 PRACTICE muft have a great advantage, by avoid* ing fuch concurrence. But, as the avoid- ing fiich concurrence may often, in the mean while, leave perfons expofed to the common infection, it merits inquiry, whether every difeafed ftate fhould reftrain from the practice of inoculation, or what are the particular difeafes that fhould do fo. This is not yet fufficiently afcertained by obfervation ; and we have frequently remarked, that the fault-pox have often occurred with a difeafed ftate of the body, without being thereby rendered more vio- lent. In particular, we have obferved, that a fcrophulous habit, or even the pre- fence of fcrophula, did not render the fmall-pox more violent; and we have ob- ferved alfo, that feveral difeafes of the fkin are equally innocent. I am of opinion, that they are the difeafes of the febrile kind, or ailments ready to induce or ag- gravate a febrile ftate, that efpecially give the OF PHYSIC. 151 the concurrence which is moft dangerous with the fmall-pox. I dare not attempt any general rules ; but I am difpofed to maintain, that, though a perfon be in a difeafed ftate, if that ftate be of uncertain nature and effeift, and at the fame time the fmall-pox be exceedingly rife, fo as to render it extremely difficult to guard againft the common infection, it will al- ways be fafer to give the fmall-pox by ino- culation, than to leave the perfon to take them by the common infection. DCVL Though inoculation has been pradlifed with fafety upon perfons of all ages ; yet, from what has actually occurred in the cafes of common infection, and from feve- ral other confiderations, there is reafon to conclude, that adults are more liable to a violent difeafe than perfons of younger years. 152 PRACTICE years. At the fame time, it is-obferved, that children, in the time of their firft den- tition, are liable, from this irritation, to have the fmall-pox rendered more violent; and that infants, before the time of den- tition, upon receiving the contagion of the fmall-pox, are liable to be affedled with epileptic fits, which frequently prove fa- tal. It is, therefore, upon the whole, evi- dent, that, though circumftances may ad- mit, and even render inoculation at any age proper ; yet, for the moft part, it will be ftill more advifeable to choofe perfons at an age, after the firft dentition is over, and before the time of puberty. DCVIL Though inoculation has been pracftifed with fafety at every feafon of the year; yet, as it is certain that the cold of winter may increafe the inflammatory, and the heats OF PHYSIC. 153 heats of fummer increafe the putrefcent ftate of the fmall-pox, it is highly probable that inoculation may have fome advantage, from avoiding the extremes either of heat or cold. DCVIII. Although the original temperament and confutations of men are not to be rea- dily changed; it is fufficiently certain, that the conditions of the human body may, by various caufes, in many refpecfls be occafionally very much changed: and therefore, as the ufe of animal food may increafe both the inflammatory and pu- trefcent ftate of the human body, fo it muft render perfons, on receiving the con- tagion of the fmall-pox, lefs fecure againft a violent difeafe; and, therefore, inocu- lation may derive fome advantage from abftinence from animal food for fome time Vol. II. L before 154 PRACTICE before the inoculation is performed: but I am of opinion, that a longer time than that ufually prefcribed may be often necef- fary; and I am perfuaded, that the Scot- tifli mothers who avoid giving their chil- dren animal food till they are paft the fmall-pox, render this difeafe in them of a milder kind. DCIX. I cannot deny that mercurial and anti- monial medicines may have fome effect in determining to a more free perfpiration, and therefore may be of fome ufe in pre- paring a perfon for the fmall-pox ; but there are many obfervations which ren- der me doubtful as to their effect. The quantity cf both thefe medicines, parti- cularly of the antimony, commonly em- ployed, is too inconfiderable to produce any effect It is true, that the mercurials have OF PHYSIC. 155 have often been employed more freely; but even their falutary e Heels have not been ' evident, and their mifchievous effects have fometimes appeared. I doubt, there- fore, upon the whole, if inoculation de- rives any advantage from thefe pretended preparatory courfes of medicines. DCX. As it has been often obferved, in the cafe of almoft all contagions, that cold, intem- perance, fear, and fome other circumftan- ces, concurring with the application of the contagion, have greatly aggravated the fu- ture difeafe, fo it muft be the fame in the cafe of the fmall-pox ; and it is undoubt- ed, that inoculation muft derive a great, and perhaps its principal, advantage, from avoiding the concurrences above men- tioned, L 2 next 156 PRACTICE DCXL It has been commonly fuppofed, that inoculation has derived fome advantage from the choice of the matter employed in it; but, from what has been obferved in DXCV. it muft appear very doubtful if any choice be neceffary, or can be of any benefit, in determining the ftate of the difcafe. DCXIL It has been fuppofed by Tome, that ino- culation has an advantage, by introducing a fmall portion only of the contagious mat- ter: But this refts upon an uncertain foun- dation. It is not known what quantity is introduced by the common infection, and it may be a fmall quantity only. Although it were larger than that thrown in by ino- culation, it is not afcertained that the cir- cum- OF PHYSIC. 157 cumftance of quantity would have any ef- fecft. A certain quantity of ferment may be neceflary to excite fermentation in a given mafs; but, that quantity given, the fermentation and aflimilation are extended to the whole mafs; and we do not find that a greater quantity than is juft necef- fary, either increafes the atftivity of the fermentation, or more certainly fecures the aflimilation of the whole. In the cafe of the fmall-pox, a confiderable difference in the quantity of contagious matter intro- duced, has not difcovered any efled in mo- difying the difeafe. DCXIIL Purging has the effedl of diminifhing the activity of the fanguiferous fyftem, and of obviating its inflammatory ftate. It is therefore probable, that the frequent ufe of cooling purgatives is a practice at- tending L 3 158 PRACTICE tending inoculation which may be of con- fiderable advantage; and, probably, it i$ alfo ufeful by diminifhing the determina- tion to the fkin. It appears to me, that mercurials and antimonials, as they are commonly managed, are ufeful only as they make a part of the purging courfe. DCXIV. It is probable, that the Rate of the fmall- pox depends very much upon the ftate of the eruptive fever, and particularly upon moderating the inflammatory ftate of the fkin ; and, therefore, it is probable, that the meafures taken for moderating the eruptive fever and inflammatory ftate of the fkin, afford the greateft improvement which has been made in the practice of inoculation. The tendency of purging, and the ufe of acids, for this purpofe, is fufliciently obvious; and upon the fame groundss OF PHYSIC. 159 grounds, we ffiould fuppofe, that blood- letting might be ufeful; but probably this has been omitted, for the fame rea- fon that perhaps might have led to the omiffion of other remedies alfo, which is, that we have found a more powerful and effectual one in the application of cold air, and the ufe of cold drink. Whatever doubts or difficulties our theory might prefent to us on this fubjedl, they may be entirely negledted, as the practice of In- doftan had long ago, and the practice of this country has lately by a large and re- peated experience, afcertained the fafety and efficacy of this remedy • and as it may and can be more certainly employed with the practice of inoculation, than it can be in cafes of common infection, it muft give a lingular advantage to the former. 1-4 DCXV. 160 PRACTICE DCXV. After the eruption, when a few pimples only, have appeared on the face, the con- tinuing the application of cold air, and the employment of purgatives, has indeed been the practice of many inoculators: but, I think, thefe practices cannot be faid to give any peculiar advantages to inoculation; for when the Hate of the eruption is de- termined, when the number of puftules is very fmall, and the fever has entirely ceafed, I hold the fafety of the difeafe to be abfolutely afcertained, and the further ufe of remedies entirely fuperfluous. In fuch cafes, I judge the ufe of purgatives to be not only unneceflary, but that they may be often hurtful. DCXVI. I have thus confidered the feveral cir- cumftances and practices accompanying ino- OF PHYSIC. 161 inoculation, and have endeavoured to af- certain the utility and importance of each. Upon the whole, I hope I have fufficiently afcertained the general utility and great ad- vantage of this practice, efpecially confiding in this, that if certain precautions, prepa- rations, and remedies, are of importance, all of them can be employed with more certainty in the practice of inoculation, than in the cafe of common infection. It remains now that I fhould offer fome remarks on the conduct of the fmall-pox, as received by infeddion, or even when, after inoculation, the fymptoms fliall prove vio- lent. The latter fometimes happens, al- though every precaution and remedy have been employed. The caufe of this is not well known; but it appears to me to be commonly owing to a difpofition of the fluids to putrefcency. But, however this may be, it will appear, that, not only in the cafe of common infeddion, but even in that 162 PRACTICE that of inoculation, there may be occafion for ftudying the conduct of this difeafe, in all its poflible varying circumftances. dcxvii. When, from the prevailing of fmall- pox as an epidemic, and more efpecially when it is known that a pcrfon not for- merly affedied with the difeafe has been expofed to the infection, if fuch perfon fhould be feized with the fymptoms of fever, there can be little doubt of its being an attack of the fmall-pox ; and therefore he is to be treated in every refpedt, as if the difeafe had been received by inocula- tion. He is to be freely expofed to a cool air, to be purged, and to have cooling acids given liberally. DCXVIII. If thefe meafures moderate the fever, no- OF PHYSIC. 163 nothing more is necefTary: But if the na- ture of the fever attacking a perfon be un- certain ; or, if with fufpicions of the fmall- pox, the fymptoms of the fever be violent; or even if, knowing the difeafe to be fmall- pox, the meafures mentioned DXCVII. fhall not moderate the fever fufficiently ; it will be proper to let fome blood; and this will be more efpecially proper, if the per- fon be an adult, of a plethoric habit, and accuftomed to full living. DCXIX, In the fame circumftances, we judge it will be always proper to give a vomit, as ufeful in the commencement of all fevers, and more efpecially in this, where a de- termination to the ftomach appears from pain and fpontaneous vomiting. DCXXo 164 PRACTICE DCXX. It frequently happens, efpecially in in- fants, that, during the eruptive fever of the fmall-pox, convulfions occur. Of thefe, if only one or two fits appear on the evening preceding the eruption, they give a favourable prognoftic of a mild difeafe, and require no remedy; but if they occur more early, and be violent and frequently repeated, they are very dangerous, and re- quire a fpeedy remedy. For this purpofe, bleeding is hardly ever of fervice; bliftering always comes too late; and the only re- medy I have found effedual, is an opiate given in a large dofe. x DCXXL Thefe are the remedies neceflary during the eruptive fever; and if, upon the erup- tion, the pimples upon the face be very few and OF PHYSIC. 165 and diftincSt, the difeafe is no further of any danger, requires no remedies, and the pur- gatives, Which, as has been laid before, are by fome practitioners continued, prove of- ten hurtful. But when, upon the eruption, the pim- ples on the face are very numerous; when they are not diftinCt; and efpecially when, upon the fifth day, the fever does not fuf- fer a confiderable remifiion; the difeafe will ftill require a great deal of attention. DCXXII. If, after the eruption, the fever fhall continue; the avoiding heat, and the con- tinuing to expofe the body to a cool air, will ftill be proper. If the fever be con- fiderabk, with a full and hard pulfe, in an adult perfon, a bleeding will be necelfary; and, more certainly, a cooling purgative. It is, however, feldom that a repetition of the 166 PRACTICE the bleeding will be proper, as a lofs of ftrength does ufually come on very foon; but the repetition of a purgative, or the frequent ufe of laxative glyfters, is com- monly ufeful. DCXXIII. When a lofs of ftrength, with other marks of a putrefcent tendency of the fluids, appears, it will be neceflary to ex- hibit the Peruvian bark in fubftance, and in large quantity. In the fame cafe, the free ufe of acids, and of nitre, is ufeful; and it is commonly proper alfo to give wine very freely. DCXXIV. From the fifth day of the difeafe, on- ward through the whole courfe of it, it is proper to give an opiate once or twice a- day, or PHYSIC. 167 day; taking care, at the fame time, to ob- viate coflivenefs, by purgatives, or laxative glyflers. DCXXV. In a violent difeafe, from the eighth to the eleventh day, it is proper to lay on bliflers fucceffively on different parts of the body, and that without regard to the parts being covered with puflules. DCXXVI. If, in this difeafe, the tumour of the fau- ces be confiderable ; the deglutition diffi- cult ; the faliva and mucus vifcid, and with difficulty thrown out; it will be proper to apply bliflers to the external fauces, and to employ diligently detergent gargles. DCXXVII. 168 PRACTICE DCXXVIL During the whole courfe of the difeafe,* when any confiderable fever is prefent, the frequent exhibition of antimonial medi- cines, in naufeating dofes, has been found ufeful; and thefe, for the moft part, fuffi- ciently anfwer the purpofe of purgatives. DCXXVIII. The remedies mentioned from DCXXIL to DCXXVI. arc thofe frequently necef- fary, from the fifth day, till the fup- puration is finifhed. But as, after that period, the fever is fometimes continued and increafed; or, as fometimes, when, after there has been little or no fever be- fore, a fever now arifes, and continues with confiderable danger; this is what is called the Secondary Fever, and requires particu- lar treatment. DCXXIX. OF PHYSIC. 169 DCXXIX. When the fecondary fever follows the 'diftind fmall-pox, and the pulfe is full and hard, the cafe is to be treated as an inflam- matory afledion, by bleeding and purging. But, if the fecondary fever follow the con- fluent fmall-pox, and be a continuance or exacerbation of the fever which had fub- flfted before, it is to be confldered as of the putrid kind; and in that cafe, bleeding is improper. Some purging may be ne- ceflary; but the remedies to be chiefly de- pended on, are the Peruvian bark and acids. When the fecondary fever firft appears, whether it is after a diftind or a confluent fmall-pox, it will be ufeful to exhibit an antimonial emetic in naufeating dofes, but in fuch manner as to produce fome vo- miting.

The eruption of the chicken-pox comes on with very little fever preceding it, or with fever of no determined duration. The pimples of the chicken-pox, more quickly than thofe of the fmall-pox, are formed into little veficles or puftules. The matter in thefe puftules remains fluid, and never acquires the colour or confiflence of the pus which appears in the puftules of the fmall-pox. The puftules of the chicken-pox are al- ways in three or four days from their firft appearance, formed into crufts. See Dr Heberden in Med. Tran fa ft. Vol. I. art. xvii. CHAP. OF PHYSIC. 173 CHAP.

At the fame time, the eye-lids are fome- what fwelled, the eyes are a little inflamed, and pour out tears ; and, together with thefe fymptoms, there is a coryza, and frequent fneezing. For the moft part, a conftant drowfinefs attends the beginning of this difeafe. DCXXXVIII. The eruption, as we have faid, common-* ly appears upon the fourth day, firfl: on M 4 the 176 PRACTICE the face, and fuccettively on the lower parts of the body. It difcovers itfelf Hrft in fmall red points; but, foon after, a number of thefe appear in clutters, which do not arife into vifible pimples, but by the touch are found to be a little promi- nent. This the cafe on the face; but on other parts of the body, the promi- nence, or roughnefs, is hardly to be per- ceived. On the face the eruption retains its rednefs, or has that increafed for two days : but, on the third, the vivid rednefs is changed to a brownilli red; and, in a day or two more, the eruption entirely difappears, while a meally defquamation takes place. During the whole time of the eruption, the face is fomewhat turgid, but feldom confiderably fwelled. DCXXXIX. Sometimes, after the eruption has ap- peared, OF PHYSIC. 177 peared, the fever ceafes entirely: but this is feldom the cafe ; and more commonly the fever continues, or is increafed after the eruption, and does not ceafe till after the defquamation. Even then the fever does not always ceafe, but continues with various duration and effect. DCXL. Though the fever happen to ceafe upon the eruption's taking place, it is common for the cough to continue till after the defquamation, and fometimes much longer. In all cafes, while the fever continues, the cough alfo continues, generally with an increafe of the difficulty of breathing; and both of thefe fymptoms fometimes arife to a degree that denotes a pneumonic affedion. This may arife at any period of the difeafe ; but very often it does not come 178 PRACTICE come on till after the defquamation of the eruption. After the fame period, alfo, a diarrhoea frequently comes on, and continues for fome time. DCXLL It is common for the mealies, even when they have not been of a violent kind, to be fucceeded by inflammatory affec- tions, particularly ophthalmia and phthir fls. DCXLIL If the blood be drawn from a vein du- ring the mealies, with the circumftances necclfary to favour the feparation of the gluten, this always appears feparated, and lying on the furface of the cralfamentum, as in inflammatory difeafes. DCXLIIL OF PHYSIC. 179 DCXLIII. For the molt part the meafles, even when violent, are without any putrid ten- dency ; but in fome cafes fuch a tendency appears, both in the courfe of the difeafe, and efpecially after the ordinary courfe of it is finifhed. See Dr Watfon, in London Med, Obfervations, Vol. IV. art. xi. DCXLIV. From what is delivered (fromDCXXXVIL to DCXLIL) it will appear, that the mea- lies are diftinguifhed by a catarrhal af- fection, and by an inflammatory diathelis to a confiderable degree; and therefore the danger attending them arifes chiefly from the coining on of a pneumonic in- flammation. PCXLV, 180 PRACTICE DCXLV. From this confideration it will be ob* vious, that the remedies efpecially necef- fary, are thofe which may obviate and diminifh the inflammatory diathefis ; and therefore, in a particular manner, blood- letting. This remedy may be employed at any time in the courfe of the difeafe, or after its ordinary courfe is finiflied. It is to be employed more or lefs according to the urgency of the fymptoms of fever, cough, and dyfpnoea; and generally may be employed very freely. But, as the fymptoms of pneumonic inflammation fel- dom come on during the eruptive fever; and, as this fever is fometimes violent im- mediately before the eruption, though a fufliciently mild difeafe be to follow; fo bleeding is feldom very neceflary during the eruptive fever, and may often be re- fer v cd OF PHYSIC. 181 ferved for the periods of greater danger which are perhaps to enfue. DCXLVI. In all cafes of mealies, where there are no marks of putrefcency, and where there is no reafon, from the known nature of the epidemic, to apprehend putrefcency, bleed- ing is the remedy to be depended upon: but alfiftance may alfo be obtained from cooling purgatives; and particularly from bliftering on the lides, or between the ihoulders. DCXLVIL % The dry cough may be alleviated by the large ufe of demulcent pectorals, mucila- ginous, oily, or fweet. It may, however, be obferved, with refpedt to thefe demul- cents, that they are not fo powerful in in- volving 182 PRACTICE volving and correcting the acrimony of the mafs of blood as has been imagined; and that their chief operation is by ber fmearing the fauces, and thereby defend- ing them from the irritation of acrids, either arifing from the lungs, or diftilling from the head. DCXLVIII. For moderating and quieting the cough in this difeafe, opiates certainly prove the mofl effectual means, whenever they can be fafely employed. In the mealies, in which an inflammatory flate prevails in a confiderable degree, opiates may be fup- pofed to be inadmiflible; and, in thofe cafes in which a high degree of pyrexia and dyfpnoea fhow either the prefence, or at leafl: the danger, of pneumonic inflamma- tion, I think that opiates might be very hurtful. In cafes, however, in which the dyfpncea OF PHYSIC. 183 dyfpncea is not confiderable, and where bleeding, to obviate or abate the inflam- matory ftate, has been duly employed, I and where the cough and watchfulnefs are the urgent fymptoms, I think that opiates may be fafely exhibited, and with great advantage. I think, further, that, in all the exanthemata, there is an acrimony dif- fufed over the fyftem, which gives a con- fiderable irritation; and, for obviating the effe&s of this, opiates are ufeful, and al- ways proper, when no particular contra- indication prevails. DCXLIX. When the defquamation of the meafles is finifhed, though there fhould then be no diforder remaining, phyficians have thought it neceffary to purge the patient feveral times, with a view to draw off the dregs of this difeafe. that is, a portion of the 184 PRACTICE the morbific matter which is fuppofed td remain long in the body. I cannot reject this fuppofition; but, at the fame time, cannot believe, that the remains of the morbific matter, diffufed over the whole mafs of blood, can be entirely drawn off by purging; and it appears to me, that, to avoid the confequences of the mealies, it is not the drawing off the morbific matter which we need to fludy, fo much as the obviating and removing the inflammatory flate of the fyftem which had been in- duced by the difeafe. With this laft viewj indeed, purging may (fill be a proper re- medy ; but bleeding, in proportion to the fymptoms of inflammatory difpofition, is yet more fo. DCL. From our late experience of the benefit of cold ail in the eruptive fever of the fmall- OF PHYSIC. 185 fmall-pox, feme phylicians have been of ) opinion, that the practice might be trans- ferred to the mealies; but we have not yet had trials Sufficient to afeertain this. There | is no doubt that external heat may be very hurtful in the mealies, as in molt other inflammatory difeafes ; and therefore the body ought to be kept in a moderate tem- perature during the whole courfe of the mealies ; but how far, at any period of the difeafe, cold air may be applied with Safety, we are yet uncertain. Analogy, though So often the refource of phyfleians, is, in general, fallacious; and further, tho' the analogy with the fmall-pox might lead to the application of cold air during the eruptive fever of the meafles, the analogy with catarrh Seems tobeagainfl: the practice. After the eruption had appeared upon the fkin, we have had many inftances of cold air making it difappear, and thereby pro- ducing much diforder in the fyflem ; and Vol. II. N have 186 PRACTICE have alfo had frequent examples of fuel! diforder being removed by reiloring the heat of the body, and thereby again bring- ing forth the eruption. CHAP. OF PHYSIC. 187 CHAP. IV. Of the Scarlet Fever. DCLI. TT may be doubted if the fcarlet fever be a difeafe fpecifically different from the cynanche maligna above defcribed. The latter is almoft always attended with a fcarlet eruption ; and, in all the inftances I have feen of what may be called the fcarlet fever, the difeafe, in almoft every perfon affected, has been attended with an ulcerous fore throat. N 2 DCLIL 188 PRACTICE DCL1I. This view of the matter may create fome doubt; but I am flill of opinion, that there is a fcarlet fever which is a difeafe fpecihcally different from the cy- nanchc maligna. Dodtor Sydenham has defcribed a fcarlet fever, which he had feen prevailing as an epidemic, with all the circumftances of the fever and eruption, without its being ac- companied with any affeciionof the throat; at leaft he does not take notice of any fuch affedlion, which fuch an accurate obferver could not fail to have done, if any fuch fymptom, as we have commonly feen ma- king a principal part of the difeafe, had attended thofe cafes which he had obferved. Several other writers have defcribed the fcarlet fever in the fame manner, and I know phylicians who have feen the dif- eafe in that form ; fo that there can be no OF PHYSIC. 189 no doubt of there being a fcarlet fever not necelfarily connected with an ulcerous fore throat, and therefore a difeafe different from the cynanche maligna. DCLIII. But, further, although in all the inftan- ces of fcarlet fever which I have feen, (and in the courfe of forty years I have feen it fix or feven times prevailing as an epidemic in Scotland), the difeafe, in almoft all the perfons affected, was attended with an ul- cerous fore throat, or was what Sauvages names the Scarlatina Anginofa; and al- though, in fome infiances, the ulcers of the throat were of a putrid and gangrenous kind, and at the fame time the difeafe in all its fymptoms refembled very exactly the cynanche maligna; yet, I am ftill per- fuaded, that not only the fcarlatina of Sydenham, but that even the fcarlatina N 3 anginofa 190 PRACTICE anginofa of Sauvages, is a different dif- eafe from the cynanche maligna; and I have formed this opinion from the follow- ing confiderations. DCLIV. ifl, There is a fcarlet fever entirely free from any affection of the throat, which fometimes prevails as an epidemic; and therefore there is a fpecific contagion pro- ducing a fcarlet eruption without any de- termination to the throat. idly, The Scarlatina, which, from its matter being generally determined to the throat, may be properly termed Anginofa, has, in many cafes of the fame epidemic, been without any affection of the throat; and therefore the contagion may be fup- pofed to be more efpecially determined to produce the eruption only. Though in all the epidemics that I OF PHYSIC. 191 I could allege to be thofe of the fcarlatina anginofa, there have been fome cafes which, in the nature of the ulcers, and in other circumftances, exaAly reiembled the cafes of the cynanche maligna ; yet I have as conftantly remarked, that thefe cafes have not been above one or two in a hundred, while the reft have all of them been with ulcers of a benign kind, and with cir- cumftances hereafter to bedefcribed, fome- what different from thofe of the cynanche maligna. y On the other hand, as I have two or three times feen the cynanche maligna epidemically prevailing; fo, among the per- fons affeAed, I have feen inftances of cafes as mild as thofe of the fcarlatina anginofa ufually are: but here the proportion was reverted; and thefe mild cafes were not one fifth of the whole, while the reft were of the putrid and malignant kind. Lafily-t It applies to the fame purpofe to N 4 192 PRACTICE obferve, that, of the cynanche maligna* mod of the inftances terminate fatally; while, on the other hand, that is the event of very few of the cafes of the fcarlatina anginofa. DCLV; From thefe confiderations, though it may appear that there is fome affinity be- tween the cynanche maligna and fcarla- tina anginofa, it will ftill remain probable that the two difeafes are fpecifically dif- ferent. 1 have been at fome pains to eRa- bliffi this opinion: for, from all my ex- perience, I find, that thofe two difeafes re- quire a different treatment; and 1 there- fore now proceed to mention more parti- cularly the circumftances of the fcarlatina anginofa. DCLVI, OF PHYSIC. 193 DCLVL This difeafe commonly appears about the beginning of winter, and continues throughout that feafon. It comes on with fome cold fhivering, and other fymptoms of the fever which ufually introduces the other exanthemata. But here there is no cough, nor the other catarrhal fymptoms which attend the mealies; nor is there that anxiety and vomiting which commonly in- troduce the confluent fmall-pox, and which more certainly introduce the Cynanche Maligna. Early in the difeafe, fome uneafinefs is felt in the throat; and frequently the de- glutition is difficult, generally more fo than in the Cynanche Maligna. Upon looking into the fauces, a rednefs and fwelling ap- pear in colour and bulk approaching to the Rate of thefe fymptoms in the Cynan- che Tonlillaris; but, in the Scarlatina, cher® 194 PRACTICE there is always more or lefs of Houghs, which feldorn appear in the Cynanche Tonfillaris; and the Houghs are commonly whiter than thofe in the Cynanche Ma- ligna. , While thefe appearances are difcovered in the fauces, upon the third or fourth day a fcarlet eruption appears on the fkin, in the fame form as defcribed in (CCCX1V.) This eruption is commonly more confi- derable and universal than in the Cynan- che; but it feldorn produces a remiffion of the the fever. The eruption for the moft part remains till the the third or fourth day after its firft appearance; but then goes off, ending in a meally defqua- mation. At this time the fever ufually fubfides ; and, generally, at the fame time, fon e degree of fweat comes on. The Houghs on the fauces, which ap- peared early in the difeafe, continue for fome days; but then falling off, difcover the OF PHYSIC. 195 the fwelling abated, and an nicer formed on one or both tonfils fhowing a laudable pus; and foon after the fever has fubfided, thefe ulcers heal up entirely. For the molt part this difeafe has much lefs of coryza attending it than the Cynanche Maligna; and, when there is a coryza attending the Scarlatina, the matter difcharged is lefs acrid, and has not the fetid fmell which it has in the other difeafe. In the Scarlatina, when the eruption has entirely difappeared, it frequently hap- pens, that, in a few days after, the whole body is affected with an anafarcous fwell- ing ; which, however, in a few days more, gradually fubfides. We have thus defcribed the moft com- mon circumftances of the Scarlatina Angi- nofa; and have only to add, that, during the time of its being epidemic, and efpe- cially upon its firfl fetting in, there are always a few cafes in which the cir- cum« 196 PRACTICE cumflances of the difeafe approach very nearly to thofe of the Cynanche Maligna; and it is only in thefe infiances that the difeafe is attended with any danger. DCLV1I. With refpecl the cure of this difeafe, when the fymptoms of it are nearly the fame with thofe of the Cynanche Maligna, it requires exactly the fame treatment as directed in (CCCXVII.) DCLV1II. When the fcarlet fever appears, without any affection of the throat, the treatment of it is very fimple, and is delivered by Dr Sydenham. An antiphlogiftic regimen is commonly all that is requifite; avoiding, on one hand, the application of cold air; anxl, Qli the other, any increafe of external heat. DCL1X, OF PHYSIC. 197 DCLIX. In the ordinary date of the Scarlatina Anginofa, the fame treatment is, in mod cafes, fudicient; but as here the fever is commonly more confiderable, and there is likewife an affedron of the throat, fome remedies may be often neceffary. DCLX. "When there is a pretty high degree of fever with a full pulfe, and a confiderable fwelling of the tonfils, bleeding is very proper, efpecially in adults; and it has been frequently pracdifed with advantage: but as, even in the Cynanche Tonfillaris, much bleeding is feldom necelfary, (CCCV.); fo, in the Scarlatina, when the flate of the fe- ver and the appearances of the fauces ren- der the nature of the difeafe ambiguous, bleeding may be omitted; and, if not alto- gether 198 PRACTICE gether avoided, it fhould at leaft not be large, and ought not to be repeated. DCLXI. Vomiting, and efpecially naufeating do- fes of emetics, notwithftanding the in- flamed ftate of the fauces, have been found very ufeful in this difeafe. An open belly is proper in every form of this difeafe; and when the naufeating dofes of emetics operate a little downwards, they are mote ferviceable. DCLXII. In every form of the Scarlatina Angi- nofa, through the whole courfe of it, de- tergent gargles fliould be employed, and more or lefs as the quantity of doughs and the vifcid mucus in the fauces may feem to require. DCLXIII. OF PHYSIC. 199 DCLXII1. Even in the milder Rates of the Scarla- tina Anginofa, it has been common with practitioners to exhibit the Peruvian bark through the whole courfe of the difeafe; but we are affured, by much experience, that in fuch cafes it may be lafely omit- ted, though in cafes any ways ambiguous it may not be prudent to neglect this re- medy. DCLXIV. The anafarcous (welling, which fre- quently follows the Scarlatina Anginofa, feldom requires any remedy; and, at leaft, the purgatives fo much inculcated, and fo commonly exhibited, foon take off the-ana- farca. CHAP. 200 PRACTICE CHAP. V. Of the Plague. sect. I. Of the Phenomena cf the Plague. DCLXV. THE Plague is a difeafe which always arifesfrom contagion; which affects many perfons about the fame time; proves fatal to great numbers; generally produ- ces OF PHYSIC. 201 ces fever; and, in moft perfons, is attend- ed with buboes or carbuncles. DCLXVI. Thefe are the circumftances which taken together give the character of the difeafe; but it is accompanied with many fymp- toms almoft peculiar to itfelf, that, in diffe- rent perfons are greatly diverfified in num- ber and degree, and fhould be particularly ftudiedi I would wilh to lay a foundation for this; but think it unfit for a perfon who has never feen the difeafe to attempt its particular hiftory. For this, therefore, I muft refer to the authors who have written on the fubjedl; but allowing thofe only to be confulted, who have themfelves feen and treated the difeafe in all its diffe-* rent forms* o Vol. II. DCLXVII. 202 PRACTICE DCLXVII. From the accounts of fuch authors, it appears to me, that the circumftances which particularly diflinguilh this difeafe, and efpecially the more violent and dan- gerous Rates of it, are, j/?, The great lofs of ftrength in the animal fundlions, which often appears ear- ly in the difeafe. The ftupor, giddinefs, and con- fequent daggering, which refembles drun- kcnnefs, or the head-ach, and various de- lirium ; which are all of them fymptoms denoting a great diforder in the fundlions of the brain. ;///)', The anxiety, palpitation, fyncope, and efpecially the weaknefs and irregularity of the pulfc, which denote a confiderable difturbance in the adlion of the heart. The naufea and vomiting, parti- cularly the vomiting of bile, which fhows an accumulation of vitiated bile in the gall- bladder OF PHYSIC. 203 bladder and biliary dudts, and from thence derived into the inteftines and fto- mach ; all of which fymptoms I fuppofe to denote a confiderable fpafm, and lofs of tone, in the extreme vefl'els on the furface of the body. ; $thly.) The buboes or carbuncles, which denote an acrimony prevailing in the fluids. And, Lafily, The petechias, hemorrhagies, and colliquative diarrhoea, which denote a pu- trefcent tendency prevailing to a great de- gree in the mafs of blood. DCLXVI1I. From the confideration of all thefe fymp- toms, it appears, that the plague is efpe- cially diftinguilhed by a fpecific contagion, often fuddenly producing the moft confide- rable fymptoms of debility in the nervous fyflem or moving powers, as well as of a general putrcfcency in the fluids ; and it O 2 is PRACTICE 204 is from the confideration of thefe circum- ftances as the proximate caufe, that I think both the prevention and cure of the plague muft be directed. DCLXIX. If this difeafe fliould revifit the northern parts of Europe, it is probable, that, at the time, there will be no phyfician then alive, who, at the firft appearance of the difeafe, can be guided by his former expe- rience, but muft be inftrudted by his ftudy of the writers on this fubject, and by ana- logy. It is, therefore, I hope, allowable for me, upon the fame grounds, to offer here my opinion with refpedt to both the prevention and cure of this difeafe. This paragraph was written before I had any notice of the plague of Mofcow anno 17715 but I think it will hill apply to the OF PHYSIC. 205 the cafe of Great Britain and of may other northern dates. SECT. H. Of the Prevention of the Plague. DCLXX. With refpeft to the prevention: As we are firmly perfuaded that the difeafe never arifes in the northern parts of Europe, but in confequence of its being imported from fome other country; fo the firft mea- fure neceflary, is the magiftrate's taking care to prevent the importation : and this may generally be done by a due attention o 3 to 206 PRACTICE to bills of health, and to the proper per- formance of quarantains. DCLXXL With rcfpect to the latter, we are per- fuaded, that the quarantain of perfons may fafely be much lefs than forty days ; and, if this were allowed, the execution of the quarantain ■would be more exadi and cer- tain, as the temptation to break it would be in a great meafure removed. DCLXXII. With refpect to the quarantain of goods; it cannot be perfect, unlefs the fufpected goods be unpacked and duly ventilated, as well as the other means employed for correcting the infeftion they may carry; and, if all this were properly done, it is probable that the time commonly prefer!- bed O F P H Y S I C. 207 bed for the quarantain of goods might alfo be fliortened. DCLXXIII. A fecond meafure, in the way of pre- vention, becomes requifite, when an in- fection has reached and prevailed in any place, to prevent that infection from spreading into other places. This can be done only by preventing the inhabitants, or the goods of any infedted place, from going out of it, till they have undergone a proper quarantain. DCLXXIV. The third meafure for prevention, to be employed with great care, is to hinder the infection from fpreading among the in- habitants of the place in which it has ari- fen. The meafures neceflary for this are O 4 to 208 PRACTICE to be directed by the dodtrine laid down in LXXXII. ; and from that doctrine we infer, that all perfons who can avoid any near communication with infected perfons, or goods, may efcape the infec- tion. DCLXXV. For avoiding fiicli communication, a great deal may be done by the maglftrate, i. By allowing as many of the inhabitants as are free from the infection, and not neceflary to the fervice of the place, to go put of it. 2. By prohibiting all affem- blies, or unneceflary intercourfe, of the people. 3. By taking care that neceflary communications be performed without contact. 4. By making fuch arrange- ments and proviflons as may render it eafy for the families remaining, to flint them- felyes up in their own houfes. 5. By al- lowing OF PHYSIC. 209 lowing perfons to quit houfes in which an infection appears, upon condition that they go into lazarettos. 9. By ventilating and purifying, or deftroying at the public expence, all infected goods. Laftly, By avoiding hofpitals, and providing fepa- rate apartments for infedled perfons. The execution of thefe mcafures will re- * quire great authority, and much vigilance and attention, on the part of themagiftrate; but it is not our province to enter into any detail on this fubject of the public police. DCLXXVI, The fourth and laft part of the bufinefs of prevention, refpedls the conduct of perfons neceflarily remaining in infected places, efpecially of thofe obliged to have fome communication with perfons infeded. DCLXXVII. 210 PRACTICE DCLXXVII. Of thofe obliged to remain in infected places, but not obliged to have any near communication with the fick, they may be preferved from the contagion by avoid- ing all near communication with other perfons, or their goods ; and, it is pro- bable, that a fmall diftance will anfwer the purpofe, if, at the fame time, there be no ftream of air to carry the effluvia of per- fons, or goods, to fome diftance. DCLXXVIIL For thofe who are neceflarily obliged to have a near communication with the lick, it is proper to let them know, that fome of the moft powerful contagions do not ope- rate, but when the bodies of men expofed to the contagion are in certain circum- ftances which render them more liable to be OF PHYSIC. 211 be affected by it, or when certain caufes concur to excite the power of it; and there- fore, by avoiding thefe circumftances and caufes, they may often efcape infection. DCLXXIX. The bodies of men are efpecially liable to be affected by contagions, when they are any ways confiderably weakened by want of food, and even by a fcanty diet or one of little nourifhment; by intemperance in drinking, which, when the ftupor of in- toxication is over, leaves the body in a weakened date ; by excefs in venery ; by great fatigue; or by any conliderable eva- cuation. DCLXXX. The caufes which, concurring with con- tagion, 212 PRACTICE tagion, render it more certainly adlive, are cold, fear, and full living. The feveral means, therefore, of avoid- ing or guarding againfl the adtion of cold (XCIV. to XGVI.) are to be carefully ftudied. DCLXXXI. Againft fear the mind is to be fortified as well as poftlble, by infpiring a favour- able idea of the power of prefcrvative means ; by deftroying the opinion of the incurable nature of the difeafe ; by occu- pying mens minds with bufinefs or labour; and by avoiding all objects of fear, as fu- nerals, pafling bells, and any notice of the death of particular friends. DCLXXXIL A full diet of animal-food increafes the irritability OF PHYSIC. 213 irritability of the body, and favours the operation of contagion; and indigeflion, whether from the quantity or quality of food, has the fame effect, DCLXXXIII. Belides giving attention tp obviate the feveral circumftances (DCX. DCLXXIX. to DCLXXXII.) which favour the opera- tion of contagion, it is probable that fome means may be employed for ftrengthening the bodies of men, and thereby enabling them to refill contagion. For this purpofe, it is probable, that the moderate ufe of wine, or of fpirituous li- quors, may have a good effect. ' It is probable alfo, that exercife, when it can be employed, if fo moderate as to be neither heating nor fatiguing to the body, may be employed with advantage. Perfons who have tried cold bathing, and commonly feel invigorating effects from 214 PRACTICE from it, if they are any ways fecure againft having already received infedion, may poflibly be enabled to relift it by the ufe of the cold bath. It is probable, that fome medicines alfo may be ufeful in enabling men to relift infection : but amongft thefe I can hardly admit the numerous alcxipharmics for- merly propofed ; or, at leaft, very few of them, and thofe only of tonic power. Amongft thefe laft we reckon the Peruvian bark; and it is perhaps the moft effectual. If any thing is to be expecfted from anti- feptics, I think camphire, whether inter- nally or externally employed, is one of the moft promiling. Every perfon is to be indulged in the ufe of any means of prefervation of which he has conceived a good opinion, whether it be a charm or a medicine, if the latter be not-direcily hurtful. Whether ilfues be ufeful in preferving from, or in moderating the c fleets of, con- tagion, OF PHYSIC. 215 tagion, I cannot determine from the ob- fervations I have yet read. DCLXXX1V. As neither the atmofphere in general, nor any confiderable portion of it, is tainted or impregnated with the matter of contagions ; fo the lighting of fires over a great part of the infedled city, or other general fumigations in the open air, are of no ufe for preventing the difeafe, and may perhaps be hurtful. DCLXXXV. It would probably contribute much to check the progrefs of infection, if the poor were enjoined to make a frequent change of cloathing, and were fuitably provided for that purpofe; and if they were, at the fame time, induced to make a frequent ventilation of their houfes and furniture. SECT. 216 PRACTICE SECT. III. Of the Cure of the Plague* DCLXXXVL In* the cure of the plague, the indica- tions are the fame as thofe of fever in ge- neral, (CXXVL); but here they are not all equally neceflary and important. DCLXXXVIL The meafures for moderating the vio- lence of reaction, which operate by minifhing the action of the heart and ar- teries OF PHYSIC. 217 teries (CXXVIIL), have feldom any place here, excepting fo far as the antiphlogiftic re- gimen is generally proper. Some phyficians, indeed, have recommended bleeding; and there may occur cafes in which bleeding may be ufeful; but, for the mod part, it is unneceffary, and in many cafes it might be very hurtful. Purging has alfo been recommended; and, in fome degree, it may be ufeful in drawing off the bile, or other putrefeent matters frequently prefentin the inteftines; but a large evacuation this way may cer- tainly be hurtful. DCLXXXVIII. The moderating the violence of reaction, lb far as it can be done by taking off the fpafm of the extreme veffels (CLI.) is a meafure of the utmoft neceffity in the cure of the plague ; and the whole of the Vol. IL P means 218 PRACTICE means (CLII. to CC.) fuited to this indica- tion are extremely proper. DCLXXXIX. The giving an emetic at the very firft approach of thedifeafe, would probably be of great fervice; and it is likely, that at fome other periods of the difeafe emetics might be ufeful, both by evacuating bile abundant in the alimentary canal, and by taking off the fpafm of the extreme veffels. DCXC. From fome principles with refpeft to fever in general, and with refpeci to the plague in particular, I am of opinion, that, after the exhibition of the firft vomit, the body fhould be difpofed to fweat; which ought to be raifed to a moderate degree only, but continued for at lead twenty- four OF PHYSIC. 219 four hours, or longer if the patient bear it ealily. DCXCL This fweating fliould be excited and con- duced agreeably to the rules laid down in CLXVI11.) It is to be promoted by the plentiful ufe of diluents, rendered more grateful by vegetable acids, or more po wer- ful by being impregnated with fome por- tion of neutral faits. DCXCII. To Support the patient under the conti- nuance of the fweat, a little weak broth, acidulated with juice of lemons, may be given frequently; and fometimes a little wine, if the heat of the body be not con- fiderable. p 2 DCXCIII. 220 PRACTICE DCXCI1I. If fudorific medicines are judged to be neceflary, opiates are the moft effectual and fafe: but they fhould not be combined with aromatics; and probably may be more effectual, if joined with a portion of emetics, and of neutral faits. DCXCIV. If, notwithftanding the ufe of emetics and fudorifics, the difeafe fhould flill con- tinue, the cure muft depend upon the employment of means for obviating de- bility and putrefcency; and, for this pur- pofe, the various remedies propofed above (from CCI. to CCXXVI1), may all be adminiflcred, bur efpecially the tonics; and of thefe the chief are cold drink and the Peruvian bark.

P 3 CHAP. 222 PRACTICE CHAP. VI. Of Erysipelas, or St Anthony'sFire, DCXCVI, IN (CCLXXIV ) I mentioned the diftinc- tion w hich 1 propofed to make betv\ een the difeafes to be named the Erythema and the Eryfipelas; and from thence it will appear, that Eryfipelas, as an Frythema following fever, may have its place here. DCXCVIL I fuppofe the eryfipelas to depend on a OF PHYSIC. 223 a matter generated within the body, and which, analogous to the other cafes of ex- anthemata, is, in confequence of fever, thrown out upon the furface of the body. I own it may be difficult to apply this to every particular cafe of eryfipelas; but I take the cafe in which it is generally fup- pofed to apply, that of the eryfipelas of the face; which I (ball therefore confider here. DCCVIII. The Eryfipelas of the face comes on with a cold {hivering, and other fymptoms of pyrexia. The hot llage of this is fre- quently attended with a confufion of head, and fome degree of delirium; and almoft always with drowfineis, or perhaps coma. The pulfe is always frequent, and com- monly full and hard. P4 DCCIX 224 PRACTICE DCXCIX. When thefe fymptoms have continued for one, two, or at mod three days, there appears, on fome part of the face, a red- nefs, fuchas that defcribed in(CCLXXV.) as the appearance of Erythema. This rednefs, at firft, is of no great extent; but gradually fpreads from the part it firft oc- cupied to the other parts of the face, com- monly till it has affected the whole; and frequently from the face it fpreads over the hairy fcalp, or defeends on fome part of the neck. As the rednefs fpreads, it commonly difappears, or at lead: decreafes, in the parts it had before occupied. All the parts upon which the rednefs appears are, at the fame time, affected with fome fwelling, which continues for fome time after the rednefs has abated. The whole face be- comes confiderably turgid; and the eye- lids OF PHYSIC. 225 lids are often fo much fwelled, as entirely to flint up the eyes. DCC. When the rednefs and fwelling have proceeded for fome time, there commonly arife, fooner or later, blitters of a larger or fmaller fize, on feveral parts of the face. Thefe contain a thin yellowifh or almoft co- lourlefs liquor,which fooner or later runs out. The fur face of the fkin, in the blittered places, fometimes becomes livid and blackifli; but this livor feldom goes deeper than the fur- face, or difcovers any degree of gangrene affecting the ikin. On the parts of the face not affected with blitters, the cuticle fuffers, towards the end of the difeafe, a confiderable d efquamation. Sometimes the tumour of the eye-lids ends in a fuppuration. DCCL 226 PRACTICE DCCI. The inflammation coming upon the face does not produce any remiflion of the fever which had before prevailed; and fometimes the fever increafes with the in- creafing and fpreading inflammation. DCCIL The inflammation ufually continues for eight or ten days ; and, for the fame time, the fever and fymptoms attending it alfo continue. DCCIIL In the progrefs of the inflammation the delirium and coma attending it fometimes go on increaflng, and the patient dies apo- ple<fl:ic on the feventh, ninth, or eleventh day of the difeafe. In fuch cafes, it has been OF PHYSIC. 227 been commonly fuppofed that the difeafe is tranflated from the external to the in- ternal parts. But I have not feen any in- itance in which it did not appear to me, that the affection of the brain was merely a communication of the external affection, as this continued increafing at the fame time with the internal. DCCIV. When the fatal event does not take place, the inflammation, after having af- fected a part, commonly the whole of the face, and perhaps the other external parts of the head, ceafes. With the inflamma- tion, the fever alfo ceafes; and, without any evident crifis, the patient returns to his ordinary Hate of health. DCCV. 228 PRACTICE DCCV. This difeafe is not commonly contagi- ous; but as it may arife from an acrid matter externally applied, fo it is poflible that the difeafe may fometimes be com- municated from one perfon to another. Perfons who have once laboured under this difeafe are liable to returns of it. DCCVI. The event of this difeafe may be fore- feen from the ftate of the fymptoms which denote more or lefs affedlion of the brain. If neither delirium nor coma come on, the difeafe is fcldom attended with any danger; but when thele fymptoms appear early in the difeafe, and are in a confider- able degree, the utmoft danger is to be apprehended. DCCV1I. OF PHYSIC. 229 DCCVII. As this difeafe often arifes in the part, at the fame time with the coming on of the pyrexia; as I have known it, with all its fymptoms, arife from an acrimony applied to the part; as it is commonly attended with a full, and frequently a hard pulfe; as the blood drawn in this difeafe fhows the fame cruft upon its furface, that ap- pears in the phlegmafiae; and, laftly, as the fwelling of the eye-lids, in this difeafe, frequently ends in a fuppuration; fo, from thefe confiderations, it feems doubtful if this difeafe be properly, in Nofology, fe- parated from the Phlegmaliae. At any rate, I take the difeafe I have defcribed to be what phylicians have named the Ery- fipelas Phlegmonodes, and that it par- takes a great deal of the nature of the Phleg- mafias. DCCVIIL PRACTICE 230 DCCV1II. Upon this conclusion, the Eryfipelas of the face is to be cured very much in the fame manner as phlegmonic inflamma- tions, by blood-letting, cooling purgatives, and by employing every part of the anti- phlogiflic regimen ; and our experience has confirmed the fitnefs of this method of cure. DCCIX. The evacuations of blood-letting and purging, are to be employed more or lefs according to the urgency of fymptoms, particularly thofe of the pyrexia, and of thofe which mark an affection of the brain. As the pyrexia continues, and often in- creafes vith the inflammation of the face; fo the evacuations mentioned may be em- ployed OF PHYSIC. 231 ployed at any time in the courfe of the dileafe. DCCX. In this, as in other difeafes of the head, it is proper to put the patient, as often as he can eafily bear it, into lomewliat of an erect pollute. DCCXI. As in this difeafe there is always an ex- ternal affeftion, and as in many inflanccs there is no other ; fo various external ap- plications to the part affedted have been propofed ; but al molt all of them are of doubtful effect. The narcotic, refrigerant, and allringent applications, are fufpedled of difpofing to gangrene ; fpiricuous appli- cations feem to increafe the inflammation; and all oily or watery applications feem to occa- 232 PRACTICE occafion its fpreading. The application that feems moft fafe, and which is now mod commonly employed, is that of a dry mealy powder frequently fptinklcd upon the inflamed parts. DCCXII. An Eryfipelas Phlegmonodes frequently appears on other parts of the body, beiide the face; and fuch other eryfipelatous in- flammations frequently end in fuppuration. Thefe cafes are feldom dangerous. At co- ming on, they are fometimes attended with drowfinefs, and even with fome de- lirium ; but this rarely happens ; and thefe fymptoms do not continue after the inflammation is formed. I have never feen an inftance of the tranllation of this inflammation from the limbs to an inter- nal part; and though thefe inflammations of the limbs be attended with pyrexia, they OF PHYSIC. 233 they feldom require the fame evacuations as the erylipelas of the face. At firft they are to be treated by dry mealy applica- tions only; and all humid applications, as fomentations, or poultices, are not to be applied, till, by the continuance of die difeafe, by the increafe of fwelling, or by a throbbing felt in the part, it appears that the dileafe is proceeding to fuppura- tion. DCCXIIL We have hitherto confidered eryfipelas as in a great meafure of a phlegmonic na- ture ; and, agreeably to that opinion, we have propofed our method of cure. But it is probable, that an eryfipelas is fome- timcs attended with, or is a fymptom of, a putrid fever ; and, in fuch cafes, the eva- cuations propofed above may be impro- per, Vol. 11. PRACTICE 234 per, and the ufe of the Peruvian bark may be neceflary ; but 1 cannot be explicit upon this fubject, as fuch putrid cafes have not come under my obfervation. CHAP. OF PHYSIC. 235 CHAP. VII. Of the Miliary Fever. DCCXIV. THIS difeafe is laid to have been un- known to the ancients, and that it appeared, for the firft time, in Saxony, about the middle of the laft century. It is faid to have fpread from thence into all the other parts of Europe ; and, fince the period mentioned, to have appeared in many countries in which it had never ap- peared before. DCCXV. PRACTICE 236 DCCXV. From the time of its having been firft particularly obferved, it has been defcri- bed and treated of by many different wri- ters; and by all of them, till very lately, has been confidered as a peculiar idiopathic difeafe. It is faid to have been conftantly at- tended with peculiar fymptoms. It comes on with a cold Rage, which is often conli- derable. The hot ftage, which fucceeds, is attended with great anxiety, and fre- quent fighing. The heat of the body be- comes great, and foon produces profufe fweating ; preceded, however, by a fenfe of pricking, as of pin-points, in the fkin; and the fweat is of a peculiarly rank and difagreeable odour. The eruption appears fooner or later in different perfons, but at no determined period of the dileafe. It feldom or never appears on the face; but dif- OF PHYSIC. 237 difcovers itfelf firft upon the neck and breaft, and from thence often fpreads over the whole body. DCCXVI. The eruption named Miliary is faid to be of two kinds, the one-named the Red, the other the White Miliary. The for- mer, which in Englifh is ftricHy named a Rafh, is commonly allowed to be a fymp- tomatic affection ; and as the latter is the only one that has any pretenlions to be confidered as an idiopathic difeafe, it is this alone that I ihall more particularly defcribe and treat of in the prefent chap- ter. DCCXVIL What then is called the White Miliary eruption, appears at firil like the red, in very 238 PRACTICE very fmall red pimples, for the moft part diftind, but fometimes cindered together. Their flight prominence is diftinguilhed better by the finger than by the eye. Soon after the appearance of this eruption, and at lead: on the fecond day, a fmall veficle appears upon the top of each pimple. At firft the veficle is whey-coloured; but foon becomes white, and ftands out like a little globule on the top of the pimple. In two or three days, thefe globules break, or are rubbed off; and are fucceeded by fmall crufts, which foon after fall off in fmall fcales. While one fet of pimples takes this courfe, another fet fucceeds ; fo that the difeafe often continues upon the fkin for many days together. Sometimes when one crop of this eruption has difappeared, another, after fome interval, is produced. And it has been further obferved, that in fbme perfons there is fuch a tendency to this difeafe, that they have been affedted with OF PHYSIC. 239 with it feveral times in the courfe of their lives. DCCXVIIL This difeafe is faid to affeft both texes, and perfons of all ages and conftitutions ; but it has been obterved, at all times, to af- fedt efpecially, and moft frequently, lying- in women. DCCXIX. This difeafe is often accompanied with violent fymptoms, and has frequently proved fatal. The fymptoms attending it, are, however, very various. They are, in one or other inftance, all the feveral fymp- toms attending febrile difeafes ; but I cannot find that any fymptom or con- courfe of fymptoms are fteadily the fame in different perfons, fo as to furnifh any 0.4 ipecifis 240 PRACTICE fpecific character to the difeafe. When the difeafe is violent, the molt common fymptoms are phrenitic, comatofe, and convulfive affections, whi. h are alfo fymp- toms of all fevers treated by a very warm regimen. DCCXX. While there is fuch a variety of fymp- toms appearing in this difeafe, it is nor to be expected that any one particular method of cure can be propofed : and according- ly we find, in different writers, different methods and remedies prefcribed; fre- quent difputes about the moft proper; and thofe received and praclifed by fome, op- pofed and rejected by others. DCCXXI. I have thus given an account of what I have OF PHYSIC. 241 have found delivered by authors who have considered the white miliary fever as an idiopathic difeate ; but, now, after having often obterved the difeate, 1 muft fay that I doubt much if it ever be fuch an idio- pathic as has been teppofed, and I fuf- pect that there is much fallacy in what has been written on the fubjeCt. DCCXXII. It teems to me very improbable, that this Ihould have been really a new elite- eafe when it was firft confidcred as fuch* There appear to me very clear traces of it in authors who wrote long before that period ; and, though there were nor, we know that the defcriptions of the ancients were inaccurate and imperfect, particularly with refpect to cutaneous affections; whilft we know alio very well, that thole affec- tions which ufuaily appeared as fympto- matic 242 PRACTICE matic only, were commonly negle&ed, of confounded together under a general ap- pellation. DCCXXIII. The antecedent fymptoms of fighing, and pricking of the fkin, which have been fpoken of as peculiar to this difeafe, are, however, common to many others; and, perhaps, to all thofe in which fweatings are forced out by a warm regi- men. Of the fymptoms faid to be concomi- tant of this eruption, there are none which can be faid to be conftant and peculiar but that of fweating. This, indeed, always precedes and accompanies the eruption; and, while the miliary eruption attends many different difeafes, it never, however, appears in any of thefe, but after fweat- ing ; and, in perfons labouring under thefe O F PHYSIC. 243 thefe difeafes, it does not appear, if fweat- ing be avoided. It is therefore probable, that the eruption is the effect of fweating; and that it is the produce of a matter, not I before prevailing in the mafs of blood, but generated, under particular circum- ftances, in the fkin itfelf. That it depends upon particular circumftances of the Ikin, appears further from hence, that the erup- tion feldom or never appears upon the face, although it affects the whole of the body belides ; that it comes upon thofe places efpecially which are more clofely covered; and that it can be brought out upon par- ticular parts by external applications. DCCXXIV. It is to be obferved, that this eruptive difeafe differs from the other exanthemata in many circumftances ; in its not being contagious, and therefore never epidemic ; that 244 PRACTICE that the eruption appears at no determined period of the difeafe; that the eruption has no determined duration; that fuccef- five eruptions frequently appear in the courfe of the fame fever ; and that fuch eruptions frequently recur in the courfe of the fame perfon's life. All thefe circumftances render it ex- tremely probable, that, in the miliary fever, the morbific matter is not a fubfifting con- tagion communicated to the blood, and thence, in confequence of fever and aflimi- lation, thrown out upon the furface of the body; but a matter occafionally produced in the Ikin itfelf, by fweating. DCCXXV. This conclufion is further rendered pro- bable from hence, that, while the miliary eruption has no peculiar fymptoms, or con- OF PHYSIC. 245 concourfe of fymptoms, belonging to it; yet, upon occaiion, it accompanies almoft all febrile difeafes, whether inflammatory or putrid, if thefe happen to be attended with fweating ; and from thence it may be prefumed, that the miliary eruption is a fymptomatic affection only, produced in the manner we have faid. DCCXXVI. But, as this fymptomatic affection does not always accompany every in (lance of fweating, it may be proper to inquire, what are the circumflances which Special- ly determine this eruption to appear ? To this, however, I can give no full and pro- per anfwer. I cannot fay that there is any one circumflance which in all cafes gives occafion to this eruption ; nor can I fay what different caufes may, in different cafes, give occalion to it. There is only one 246 PRACTICE one obfervation I can offer to the purpofc of this inquiry; and it is, that, of the per- fons fweating under febrile difeafes, thofe are efpecially liable to the miliary erup- tion, who have been prevjoufly weakened by large evacuations, particularly of blood. This will explain why it happens to lying- in women more frequently than to any other perfons; and to confirm this expla- nation, I have remarked, that the eruption happened to women not in childbed, but who had been much fubjedled to a fre- quent and copious menftruation, and to an almoft conftant fluor albus. I have alfo had occafion to obferve it happen to men in fevers, after wounds from which they had fuffered a great lofs of blood. Further, that this eruption is produced by a certain ftate of debility, will appear probable, from its often occurring in fe- vers of the putrid kind, which are always attended with great debility. It is true, that OF PHYSIC. 247 that it alfo fometimes attends inflamma- tory difeafes, when it cannot be accounted for in the fame manner; but I believe it will be found to attend efpecially thofe in- flammatory difeafes in which the fweats have been long protraCled or frequently repeated, and which have thereby produ- ced a debility, and perhaps a debilitating putrid diathefis. DCCXXVIL It appears fo clearly to me that this erup- tion is always a fymptomatic and factitious that I am perfuaded it may be in moft cafes prevented merely by avoid- ing fweats. Spontaneous fweatings, in the beginning of difeafes, are very rarely cri- tical ; all fweatings, not evidently critical, Ihould be prevented ; and the promoting them, by increafing external heat, is com- monly very pernicious. Even critical fweats 248 PRACTICE fweats fhould hardly be encouraged by fuch means. If, therefore, fpontaneous fweats arife, they are to be checked by the coolnefs of the chamber ; by the lightnefs and loofenefs of the bed-clothes ; by the perfons laying out their hands and arms, and by their taking cold drink : and, by thefe precautions, 1 think I have frequently prevented miliary eruptions, which were otherwife likely to have appeared, parti- cularly in lying-in women. DCCXXVIIL But it may happen, when thefe precau- tions have been neglected, or from other circumftances, that a miliary eruption does actually appear ; and the queftion will then be put, how the cafe is to be treated? It is a queftion ot confequence, becaufe I believe that the matter here generated is often of a virulent kind ; it is frequently the OF PHYSIC. 249 the offspring of putrefcency; and, when, treated by increaling the external heat of the body, it feems to acquire a virulence which produces thofe fymptoms men- tioned in (DGCX1X.), and proves cer- tainly fatal. It has been an unhappy opinion with moft phyiicians, that eruptive difeafes were ready to be hurt by cold; and that it was therefore necelfary to cover up the body very clofely, fo as thereby to increafe the external heat. We now know that this is a miftaken opinion; that increaling the external heat of the body is very generally mifehievous; and that feveral eruptions not only admit, but require the application of cold air. We are now perfuaded, that the practice which formerly prevailed, in the cafe of miliary eruptions, of covering up the body clofe, and both by external means, and internal remedies, encouraging the fweatings which accompany this erup- tion, Vol. II. R 250 PRACTICE tion, was highly pernicious, and common- ly fatal. I am therefore of opinion, even when a miliary eruption has appeared, that in all cafes where the fweating is not ma- nifeflly critical, we fhould employ all the feveral means of flopping it that are men- tioned above ; and I have fometimes had occafion to obferve, that even the admif- iion of cool air was fafe and ufeful. DCCXXIX. This is, in general, the treatment of mi- liary eruptions ; but, at the fame time, the remedies fuited to the primary difeafe are to be employed; and therefore, when the eruption happens to accompany inflamma- tory affedlions, and when the fulnefs and hardnefs of the pulfe or other fymptoms fhow an inflammatory ftate prelent, the cafe is to be treated by bloodletting, pur- ging, and other antiphlogiftic remedies. Upon OF PHYSIC. 251 Upon the other hand, when the miliary eruption attends difeafes in which debility and putrefcency prevail, it will be proper to avoid all evacuations, and employ tonic and antifeptic remedies, particularly the Peruvian bark, cold drink, and cold air. I (hall conclude this fubjeCt with men- tioning, that the venerable octogenarian practitioner, de Fifcher, when treating of this fubject, in laying down the indications of cure, has given this as one of them: ' Excretionis peripheries non primariam * habere rationem.'

It is my delign to reftore this diftinc- tion ; and 1 {hall therefore here, under the title of Hemorrhagies, comprehend thofe only which have been commonly called Active, that is, thofe attended with fome degree of pyrexia ; which feem always to depend upon an increafed impetus of the Iplood in the velTels pouring it out, and which 258 PRACTICE which chiefly arife from an internal caufe. In this I follow Dr Hoflman, who joins the active hemorrhagies with the febrile difeafes; and have accordingly eftablifhed thefe hemorrhagies as an order in the clafs of Pyrexia?. From this order I exclude all thofe effiifions of red blood that are owing entirely to external violence; and all thofe which, though arifing from internal caufes, are, however, not attended with pyrexia, and which feem to be owing to a putrid fluidity of the blood, to the weaknefs or to the erofion of the veflels, rather than to any increafed impetus of the blood in them. DCCXXXVII. Before proceeding to treat of tliofe pro- per hemorrhagies which form an order in our Noiology, I fhall treat of active hemor- rhagy in general; and indeed the feveral genera O F PHYSIC. 259 genera and fpecies to be treated of parti- cularly afterwards, have fo many circum- ftances in common with one another, that the general coniideration to be now offered will prove both proper and ufeful. SECT. I. Of the Phenomena DCCXXXV1II. The phenomena of hemorrhagy are generally the following. Hemorrhagies happen efpecially in ple- thoric habits, and to perfons of a fanguinc temperament. They appear moft com- monly in the fpring, or in the beginning of ftimmer. for fome time, longer or fliorter in dif- ferent 260 PRACTICE ferent cafes, before the blood flows, there are fome fymptoms of fulnefs and tenfion about the parts from whence the blood is to iiTue. In fuch parts as fall under our view, there are fome rednefs, fwelling, and fenfe of heat or of itching; and in the internal parts, from which blood is to flow, there is a fenfe of weight and heat; and, in both cafes, various pains are often felt in the neighbouring parts. DCCXXXIX. When thefe fymptoms have fubfifted for fome time, fome degree of a cold ftage of pyrexia comes on, and a hot ftage is form- ed; during which, the blood flows of a florid colour, in a greater or lefler quan- tity, and continues to flow for a longer or fliorter time; but commonly, after fome time, the effulion fpontaneoufly ceafes, and together with it the pyrexia alfo. DCCXL. OF PHYSIC. 261 DCCXL. During the hot ftage which precedes an hemorrhagy, the pulfe is frequent, quick, full, and often hard; but, as the blood flows, the pulfe becomes fofter and lefe frequent. DCCXLI. In hemorrhagies, blood drawn from a vein, does, upon its concreting, commonly fliow the gluten feparated, or a cruft formed, as in the cafes of Phlegmafise. DCCXLII. Hemorrhagies, from internal caufes, having once happened, are apt, after a cer- tain interval, to return; in fome cafes very often, and frequently at Rated periods. DCCXLIIL 262 PRACTICE DCCXLIII. Thefe are, in general, the phenomena of hemorrhagy; and if in fome cafes all of them be not exquifitely marked, or if per- haps fome of them do not at all appear, it imports only, that, in different cafes, the fyftem is more or lefs generally rflccled ; and that, in fome cafes, there are purely topical hemorrhagies, as there are purely topical inflammations. SECT. OF PHYSIC. 263 SECT. II. Of the Proximate Cause o/'Hemorrhagy, DCCXLIV. The pathology of hemorrhagy feems to be fufficiently obvious. Some inequality in the diftribution of the blood, occalions a congeftion in particular parts of the fan- guiferous fyftem; that is, a greater quantity of blood is poured into certain vefiels than their natural capacity is iuitcd to receive. Thefe veffels become, thereby, preternatu- rally diflended ; and this diftention, pro- ving a ftimuhis to them, excites their ac- tion to a greater degree than ufual, which, pufh- 264 PRACTICE pufhing the blood with unufual force in- to the extremities of thefe veffels, opens them by anailomofis, or rupture ; and, if thefe extremities be loofely fituated on ex- ternal furfaces, or on the internal furfaces of certain cavities that open outwardly, a quantity of blood flows out of the body. DCCXLV. This reafoning will, in fome meafurej explain the production of hemorrhagy. But it appears to me, that, in mod cafes, there are fome other circumftances that concur to produce it: for it is probable, that, in confequence of congeftion, a fenfe of refiftance arifes, and excites the action of the Vis Medicatrix Naturae ; the exer- tions of which are ufually made by the formation of a cold ftage of pyrexia, indu- cing a more vigorous adion of the veflels; and the concurrence of this exertion more cfiec* OF PHYSIC. 265 effectually opens the extremities, and occa- flons the flowing out of the blood. DCCXLVI. What has been delivered in the two pre- ceding paragraphs, fcems to explain the whole phenomena of hemorrhagy, except the circumftance of its frequent recurrence, which I apprehend may be explained in the following manner. The congeflion and confequent irritation being taken ofF by the flowing of the blood ; this, there- fore, foon after, fpontaneoufly ceafes; but, at the fame time, the internal caufes which had before produced the unequal diftribu- tion of the blood, commonly remain, and muft now operate the more readily, as the over-ftretched and relaxed veflels of the part will more ealily admit of a congeflion of blood in them, and, confequently, pro- duce Vol. II. S 266 PRACTICE duce the fame feries of phenomena as be- fore. DCCXLVII. This may fufliciently explain the ordi- nary return of hemorrhagy : but there is ftill another circumftance, which, as com- monly concurring, is to be taken notice of; and that is, the general plethoric hate of the fyftem, which renders every caufe of unequal diftribution of more confiderable effect. Though hemorrhagy may often depend upon the ftate of tne veffels of a particular part being favourable to a con- geftion's being formed in them ; yet, in order to that hate's producing its effect, it is neceffary that the whole fyftem fhould be at leaft in its natural plethoric condi- tion ; and, if this fhould be in any degree increafed tyeyond wrhat is natural, it will ftill more certainly determine the effects of OF PHYSIC. 267 of topical confciir ation to take place. T he return of hemorrhagy, therefore, will be more certainly occafioned, if the fyftem becomes preternaturally plethoric ; but hemorrhagy has always a tendency to in- creafe the plethoric ftate of the f) item, and, conl'equently, to occaflon its own re- turn. DCCXLVIII. To fhew that hemorrhagy does contri- bute to produce or increafe the plethoric ftate of the fyftem, it is only neceflary to obferve, that the quantity of ferous fluids being given, the ftate of the excretions de- pends upon a certain balance between the force of the larger arteries propelling the blood, and the refiftanceof the excretories: but the force of the arteries depends upon their fulnefs and diftention, chiefly given to them by the quantity of red globules and S 2 gluten, 268 PRACTICE gluten, which are, for the greateft part, con- fined to the red arteries; and therefore, the Jpoliatwn made by an hemorrhagy, being chiefly of red globules and gluten, the ef- fufion of blood mull leave the red arteries more empty and weak. In confequence of the weaker adlion of the red arteries, the excretions are in proportion diminifhed; and, therefore, the ingefta continuing the fame, more fluids will be accumulated in the larger veflels. It is by this means that the lofs of blood by hemorrhagies, whether artificial or fpontaneous, if vrithin certain bounds, is commonly fo foon recovered : but, as the diminution of the excretions, from a lefs quantity of fluid being impelled into the excretories, gives occafion to thefe veflels to fall into a contradied ftate; fo, if this fliall continue long, thefe veflels will become more rigid, and will not yield to the fame impelling force as before. Al- though the arteries, therefore, by new blood OF PHYSIC. 269 blood collected in them, {hall have reco- vered their former fulnefs, tenfion, and force, yet this force will not be in balance with the refiftance of the more rigid ex- crctories, fo as to reftore the former {late of excretion ; and, confequently, a further accumulation will take place in the arteries, and an increafe of their plethoric (late be thereby induced. In this manner, we per- ceive more clearly, that hemorrhagy, as producing a more plethoric flate of the fyftem, has a tendency to occalion its own recurrence with greater violence ; and, as the renewal and further accumulation of blood require a determinate time, fo, in the feveral repetitions of hemorrhagy, that time will be nearly the fame; and therefore the returns of hemorrhagy will be commonly at Rated periods, as has been obferved frequently to happen. 8 3 DCCXLIX. 270 PRACTICE DCCXLIX. I have thus explained the nature of he- morrhagy in general, as depending upon fomc inequality in the diftribution of the blood, occafioning a congeftion of it in particular parts of the fanguiferous fyftem. It is indeed probable, that, in moft per- fons, the feveral parts of the fanguiferous fyftem are in balance with one another; and that the denfity, and confequently the refinance, in the feveral veflels, is in pro- portion to the quantity of blood which each fhould receive ; from whence it fre- quently happens, that no inequality in the diftribution of the blood takes place in the courfe of a long life. If, however, we con- fider that the fanguiferous fyftem is con- ftantly in a plethoric ftate, that is, that the vefiels are conftantly diftended beyond that fize which they would be of, if free from any diftending force, we fiiall be fatif- OF PHYSIC. 271 fatisfied that this hate may be readily changed. For as, on the one hand, the veflels are elaftic, fo as to be under a con- ftant tendency to contraCi upon the with- drawing of any part of the ditlending force; and, on the other hand, are not fo rigid but that, by an increafe of the impetus of the blood in them, they may be more than ordinarily di (tended ; fo we can eafilv un- derhand how, in moft perfons, caufes of an increafed contraction or diflention may arife in one part or other of the fyflem, or that an unequal diftribution may take place ; and how, in an exquifitely di (tended or plethoric fyftem, a fmall inequality in the diftribution of the blood may form thofe congeftions which give occafion to hemorrhagy. DCCL. In this manner I endeavour to explain S 4 how 272 PRACTICE how hemorrhagy may be occafioned at any period of life, or in any part of the body: but hemorrhagies happen in certain parts more frequently than in others, and at cer- tain periods of life more readily than at others ; and therefore, in delivering the general doctrine of hemorrhagy, it may be required that I fhould explain thofe cir- cumflances which produce the fpecialities mentioned; and I fhall now attempt it. DCCLI. The human body, from being of a fmall bulk at its fir ft formation, grows after- wards to a conliderable fize. This increafe of bulk confills, in a great meafure, in the increafe of the quantity of fluids, and a proportional enlargement of the contain- ing veflels. But, at the fame time, the quantity of folid matter is alfo gradually increafed ; and, in whatever manner we may OF PHYSIC. 273 may fuppofe this to be done, it is probable that the progrefs, in the whole of the growth of animal bodies, depends upon the extenfion of the arterial fyftem; and fuch is the conftitution of the fanguiferous fyftem, that the motion of the blood in the arteries has a conftant tendency to extend them in every dimenfion. DCCLII. As the ftate of the animal-fol id is, at the firft formation of the body, very lax and yielding; fo the extenfion of the fyftem proceeds, at firft, very faft: but, as the ex- tenfion gives occafion to the appofition of more .matter to the folid parts, thefe are, in proportion to their extenfion, conftantly acquiring a greater denfity, and therefore giving more refiftance to their further ex- tenfion and growth. Accordingly, we ob- serve, that as the growth of the body ad- • vances, 274 PRACTICE vances, its increafe in any given time, be- comes proportionally lefs and lefs, till at length it ceafes altogether. DCCLIIL This is the general idea of the growth of the human body, till it attain the utmoft bulk which it is capable of acquiring; but, it is to be remarked, that this growth does not proceed equally in every part of the body, it being requifite for the oeconomy of the fyftem, that certain parts fliould be firft evolved, and fhould alfo acquire their full bulk fooner than others. This appears particularly with refpeft to the head, the parts of which appear to be firft evolved, and fooneft to acquire their full fize. DCCLIV. To favour this unequal growth, it is pre- fumed, OF PHYSIC. 275 fumed, that the dimenfions or the laxity of the veffels of the head, or that the direction of the force of the blood, are adapted to the purpofe; and from what has been faid in (DCCLIL), it will alfo certainly follow, that as the veffels of the head grow fafteft, and fooneft acquire their full fize, fo they will fooneft alfo acquire that denfity which will prevent their further extenfion. While, however, the force of the heart, and the quantity of the fluids, with refpecl to the whole fyftem, remain the fame, the dif- tending and extending powers will be di- rected to fuch parts as have not yet acqui- red the fame denfity and dimenfions as thofe firfl: evolved ; and thus the diftending and extending powers will proceed to ope- rate till every part of the fyftem, in refpecl of denfity and refiftance, fhall have been brought to be in balance with every other, and till the whole be in balance with the force of the heart, io that there can be no further 276 PRACTICE further growth in any particular part, un- Jefs fome preternatural circumnance fhall happen to arife. DCCLV. In this procefs of the growth of the bo- dy, as it feems in general to depend upon ,a certain balance between the force of the heart, or diflending power, and the refin- ance of the folids ; fo it will appear, that? while the folids remain very lax and yield- ing, fome occaflonal increafe of the dif- tending power may arife without produ- cing any very perceptible diforder in the fyflem. But, it will alfo appear, that, in proportion as the diflending power and re- finance of the folids come to be more near- ly in exadl balance with one another, fo any increafe of the didending power will more readily produce a rupture of veflels, which do not eafily yield to extenfion. DCCLVI. OF PHYSIC. 277 DCCLVI. From all this, it mu ft follow, that the effects of any unufually plethoric ftate of the fyftem, will be different according as this ihall occur at different periods of the growth of the body. Accordingly, it is evi- dent, that if the plethoric ftate arifes while the head is yet growing, and while the de- termination of the blood is ftill more to the head than to the other parts, the in- creafed quantity of the blood will be efpe- cially determined to the head; and as there alfo, at the fame time, the balance between, thediftending and extending powers is moft nearly adjufted, fo the determination of the blood will moft readily produce in that part a rupture of the veffels, or an hemor- rhagy. Hence it is, that hemorrhagies of the nofe fo frequently happen in young . perfons ; and in thefe more readily, as they approach nearer to their acme, or full growth; 278 PRACTICE growth ; or, it may be faid, perhaps more properly, as they approach nearer to the age of puberty, when, perhaps, in both fexes, but efpecially in the female, a new deter- mination arifes in the fyllem. DCCLVIL The determination of agreater quantity of blood to the veifels of the head, might be fuppofed to occafion a rupture of veifels in other parts of the head, as well as in the nofe: but fuch a rupture does not com- monly happen ; becaufe in the nofe, there is, for the purpofe of fenfe, a conliderable net-work of blood veifels expanded on the internal furface of the noftrils, and covered only with thin and weak teguments. From this circumftance it is, that upon any in- creafed impetus of the blood in the veifels of the head, thofe of the nofe are mod ea- fily broken; and the effulion from the nofe taking OF PHYSIC. 279 taking place, it not only relieves the other ex- tremities of the external carotid, to which the arteries of the nofe chiefly belong, but relieves alfo, in a great meafure, the fyftena of the internal carotid. For, from the in- ternal carotid, certain branches are fent to the nofe, are fpread out on its internal furface, and probably inofculated with the extremities of the external carotid: fo that, whichfoever of the extremities are broken, the vis derivation! s of Haller will take place ; the effufion will relieve the whole fanguiferous fyftem of the head ; and the fame eflulion will alfo commonly prevent an hemorrhagy happening at the fame time in any other part of the body. DCCLVIII. From thefe principles, it will appear why hemorrhagies of the nofe, fo frequent be- fore the period of puberty, or of the acme, feldom 280 PRACTICE feldom happen after thefe periods : and J muft obferve further, that although they fhould occur, they would not afford any objection to my doctrine, as fuch hemor- rhagies might be imputed to a peculiar laxi- ty of the velfels of the nofe, and perhaps to a habit acquired with refpect to thefe velfels, while the balance of the fyftem might be otherwife duly adjulted. DCCLIX. When the procefs of the growth of the body goes on regularly, and the balance of the fyftem is properly adjuRed to the gra- dual growth of the whole, as well as to the fucceflive growth of the feveral parts, even a plethoric Rate does not produce any he-, morrhagy, or at lead: any after that of the nofe : but if, while the plethoric Rate con- tinues, any inequality fliall alfo fubfiR in any of the parts of the fyRem, congeRions, hemorrhagic O F PH Y S I C. 281 hemorrhagic or inflammatory, may be ftill readily formed. DCCLX. In general, it may be obferved, that, when the feveral parts of the fyftem of the aorta have attained their full growth, and are duly balanced with one another, if then any confiderable degree of plethora remain or arife, the nicety of the balance will be between the fyftems of the aorta and pul- monary artery, or between the veflels of the lungs and thofe of all the reft of the body. And although the lefler capacity of the veflels of the lungs is commonly com- penfated by the greater velocity of the blood in them ; yet, if this velocity be not always adjufted to theneceflary compenfa- tion, it is probable that a plethoric ftate of the whole body will always be efpecially felt in the lungs $ and, therefore, that an VOL. II. T hemor- 282 PRACTICE hemorrhagy, as the effect of a general ple- thora, may be frequently occafioned in the lungs, even though there be no fault in their conformation. DCCLXI. In fome cafes, perhaps, an hemorrhagy from the lungs, or an hemoptyiis, does arife from the general plethoric Rate of the body; but an hemoptyiis more frequently does, and may be expe&ed to happen, from a faulty proportion between the capacity of the lungs and that of the reft of the body. DCCLXII. When fuch a difproportion takes place, it will be evident, that an hemoptyiis will efpecially happen about the time that the body is approaching to its acme; that is, when OF PHYSIC. 283 when the fyftem of the aorta has arrived at its utmoft extenfion and reliftance, and when, therefore, the plethoric Rate of the whole muR efpecially affect the lungs. DCCLXIII. Accordingly, it lias been conftantly ob- ferved, that the hemopty fis efpecially oc- curs about the time of the body's arriving at its acme'; but I muft remark alfo, that the hemorrhagy may occur fooner or later, ac- cording as the balance between the velTels of the lungs, and thofe of the fyftem of the aorta, happens to be more or lefs exadly ad- jured to one another; and it may there- fore often occur much later than the pe- riod mentioned, when that balance, though not quite even, is however not fo ill ad- jufted, but that fome other concurring caufes are neceffary to give it effect. T 2 DCCLXIV. 284 PRACTICE DCCLXIV. It was anciently remarked by Hippocra- tes, and has been confirmed by modern obfervation, that the hemoptyfis generally occurs in perfons between the age of fifteen and that of five-and-thirty ; that it may happen at any time between thefe two pe- riods ; but that it feldom happens before the former, or after the latter; and it may be proper here to inquire into the reafon of thefe two limitations. DCCLXV. With refpe6l to the firft, the rea- fon of it has been already explained in (DCCLXII. and DCCLXIIL). With refpedl to the fecond limitation, I expedl: that the reafon of it will be under- ftood from the following confiderations. I OF PHYSIC. 285 It has been already obferved, that the ex- tenfion and growth of the body require the plethoric Rate of the arterial fyftem; and nature has provided for this, partly by the conftitution of the blood being fuch, that a great portion of it is unfit to pafs into the exhalants and excretories ; partly by giving a certain denfity and refiftance to the feveral exhalants and excretories thro' which the fluids might pafs out of the red arteries; and partly, but efpecially, by a refiftance in the veins to the free paflage of the blood into them from the arteries. DCCLXVI. With refpecft to this laft and chief cir- cumftance, it appears from the experi- ments of Sir Clifton Wintringham, in his Experimental that the propor- tional denlity of the coats of the veins to that of the coats of the arteries, is greater in T3 young 286 PRACTICE young than in old animals : From which it may be prefumed, that the reliftance to the paflage of the blood from the arte- ries into the veins, is greater in young ani- mals than in old; and, while this reliftance continues, the plethoric ftate of the arte- ries muft be conftantly continued and fup- As however the denfity of the coats of the veflels, confifting chiefly of a cellular texture, is increafed by preflure; fo, in pro- portion as the coats of the arteries are more expofed to preflure by diftention than thofe of the veins, the former, in the progrefs of the growth of the body, muftincreafe much more in denfity than the latter; and,there- fore, the coats of the arteries, in rcfpecl of denfity and reliftance, muft come, in time, not only to be in balance with thofe of the veins, but to prevail over them: a fact which is fufliciently proved by the experi- ments of the above-mentioned ingenious author. By OF PHYSIC. 287 By thefe means, the proportional quan- tities of blood in the arteries arid veins muft change in the courfe of life. In younger animals, the quantity of blood in the arteries muft be proportionally greater than in old ones ; but, by the in- creaiing denfity of the arteries, the quan- tity of blood in them muft be continually diminifhing, and that in the veins be proportionally increaling, fo as at length to be in a proportionally greater quantity than that in the arteries. When this change happens in the proportional quantities of the blood in the arteries and veins, it muft be evident that the plethoric ftate of the arte- ries will be in a great meafure taken off; and, therefore, that the arterial hemorrhagy is no longer likely to happen; but that, if a general plethoric ftate afterwards take place in the fyftem, it muft efpecially ap- pear in the veins. t4 dcclxvil 288 PRACTICE DCCLXVII. The change I have mentioned to hap- pen in the date of the arterial and venous fyftems, is properly fuppofed to take place in rhe human body about the age of thirty- five, when it is manifeft that the vigour of the body, which depends fo much upon the fullnefs and tenfion of the arterial fyftem, no longer increafes ; and therefore it is, that the fame age is the period, after which the arterial hemorrhagy, hemopty fis, hardly ever appears. It is true,there are inftances of the hemoptyfis happening at a later period; but it is for the reafons given (DCCLVIII.) which fhow that an hemorrhagy may hap- pen at any period of life, from accidental caufes forming congeftions, independent of the ftate of the balance of the fyftem at that particular period* pccLxvin, OF PHYSIC. 289 DCCLXVIIL I have faid, (DCCLXVL), that if, after the age of thirty-five, a general and preter- natural plethoric ftate occur, it muft efpe- cially appear in the venous fyftem ; and I muft now obferve, that this venous ple- thora may alfo give occafion to hemor- rhagy. DCCLXIX. If a plethoric ftate of the venous fyftem take place, it is to be prefumed, that it will efpecially and in the firft place affect the fyftem of the vena portarum, in which the motion of the venous blood is more flow than elfewhere; in which the motion of the blood is little affifted by external com- preffion; and in which, from the want of valves in the veins that form the vena portarum, the motion of the blood is little aflifted 290 PRACTICE affifted by the compreilion that is applied; while, from the fame want of valves in thofe veins, the blood is more ready to re- gurgitate in them. Whether any regurgi- tation of the blood can produce an action in the veins, and which inverted, or di- rected towards their extremities, can force thefe, and occafion hemorrhagy, may per- haps be difputed: but it appears to me that an hemorrhagy, produced by a plethoric Rate of the veins, may be explained in ano- ther and more probable manner. If the blood be accumulated in the veins, from any interruption of its proper courfe, that accumulation muft refill the free paflage of the blood from the arteries into the veins. This again, muft produce fome con- geftion in the extremities of the red arte- ries, and therefore fome increafcd adlion in them, which muft be determined with more than ufual force, both upon the ex- tremities of the arteries, and upon the ex- halants OF PHYSIC. 291 halants proceeding from them ; and this force may occafion an effufion of bloody either by anaflomofis, or rupture. DCCLXX. In this manner I apprehend the hemor-» rhoidal flux is to be explained, fo far as it depends upon the flate of the whole fyflem. It appears mofl commonly to proceed from the extremities of the hemorrhoidal veflels, which, being the mofl dependent and diflant branches of thofe veins that form the vena portarum, are therefore the mofl readily affefled by every accumulation of blood in that fyflem of veins, and confe- quently by any general plethora in the venous fyflem. DCCLXXI. It is here to be obferved, that I have fpoken 292 PRACTICE fpoken of this hemorrhagy as proceeding from the hemorrhoidal veffels only, as in- deed it molt commonly does ; but it will be readily underftood, that the fame accu- mulation and refiftance to the venous blood may, from various caufes, affect many of the extremities of the vena portarum, which lie very fuperficially upon the internal furface of the alimentary canal, and give occafion to what has been called the Mor- bus .Niger or Melina, DCCLXXIL Another part, in which an unufually ple- thoric ftate of the veins may have particu- lar effects, and occafion hemorrhagy, is the head. In this, the venous fyftem is of a peculiar conformation, and fuch as feems intended by nature to give there a flower motion to the venous blood. If, therefore, the plethoric flate of the venous fyftem in general, OF PHYSIC. 293 general, which Teems to increafe as life ad- vances, fliould at length increafe to a great degree, it may very readily affedt the ve- nous veflels of the head, and produce there fuch a refinance to the arterial blood, as to determine this to be poured out from the nofe, or into the cavity of the cranium. The fpecial effect of the latter effufion will be, to produce the difeafe termed Apoplexy; and which, therefore, is properly named by Dodtor Hoffman, Hemorrbagia Ce- rebri : and the explanation of its caufe, which I have now given, explains well why it happens efpecially to men of large heads and fhort necks, and to men in the decline of life, when the powers promoting the motion of the blood are much weak- ened. DCCLXXI1I. I have thus attempted to give the hiftory of 294 PRACTICE of the plethoric and hemorrhagic Rates of the human body, as they occur at the dif- ferent periods of life; and hope I have thereby explained, not only the nature of hemorrhagy in general, but alfo of the particular hemorrhagies which moft com- monly appear, and as they occur fuccef- fively at the different periods of life. SECT. III. Of the Remote Causes DCCLXX1V. In the explanation hitherto given, I have specially confidered the predifpofition to liemor- OF PHYSIC. 295 hcmorrhagy ; but it is proper alfo, and even neceflary, to take notice of the occa- fional caufes, which not only concur with the predifponent, in exciting hemorrhagy, but may alfo fometimes be the foie caufes of it. DCCLXXV. Thefe occafional caufes are, i. External heat, which, by rarefying the blood, produces or increafes the plethoric ftate of the body; and the fame heat, as giving a ftimulus to the whole fyftem, mutt urge any particular determinations before eftablifhed, Rill further, or may urge to excefs any inequality, otherwife innocent; fo that, in either way, external heat may immediately excite hemorrhagies, to which there was a predifpofition, or may form congeRions where there were none before, and thereby occafion hemorrhagy. 2. A 296 PRACTICE 2. A confiderable and fudden diminu- tion of the weight of the atmofphere, which feems to occafion the fame effects as heat, by producing alfo an expanfion of the blood. 3. Whatever increafes the force of the circulation, and thereby the velocity of the blood, may operate in the fame manner as heat, in urging not only previous deter- minations with violence, but alfo in urging to excefs inequalities, otherwife innocent. All violent exercife, therefore, and efpe- cially all violent efforts, which, not only by a larger and longer infpiration, but alfo by the fimultaneous action of many muf- cles interrupting the free motion of the blood, impel it with unufual force into the extreme veffels more generally, and, according to the different poftures of the body, and mode of the effort, into certain veffels more particularly. Among the caufes increaling the force of OF PHYSIC. 297 of the circulation, anger and other violent active paflions are to be reckoned. 4. The violent exercife of particular parts of the body. If thefe are already affected with congeftions, or liable to them, filch exercife may be conildered as a fti- mulus applied to the veflels of that parti- cular part. Thus, any violent exercife of refpiration may excite hemoptyfis, or occa- fion its return. 5. The poftures of the body increaling determinations, or ligatures occafioning accumulations of the blood in particular parts of the body. 6. A determination into certain veflels rendered habitual by the frequent repeti- tion of hemorrhagy from them. , 7. Cold, externally applied, as changing the diftribution of the blood, and deter- mining it in greater quantity into the in- ternal parts. Vol. II. U SECT, 298 PRACTICE SECT. IV. Of the Cure of Hemorrhagy. DCCLXXVI. Having thus confidered the proximate and remote caufes of hemorrhagy in gene- ral, cur next bufinefs is, to treat of the cure of the difeafe in the fame manner. In entering upon this fubjeft, the firft queftion which prefents itfelf, is, Whether the cure of hemorrhagies ought to be at- tempted by art, or if they Ihould be left to the conduct of nature ? DCCLXXVII. OF PHYSIC. 299 DCCLXXVII. The latter opinion was the favourite doc- trine of the celebrated Dr Stahl, and his followers. They that the hu- man body is much difpofed to a plethoric ftate; and, confequently, to many dis- orders which nature endeavours to obviate and relieve by exciting hemorrhagy: that this, therefore, is often neceflary to the balance and health of the fyftem : that it is accordingly to be generally encouraged, fometimes folicited, and is not to be fuppreffcd, unlefs when it goes to great excefs, or happens in parts in which it may be dangerous* DCCLXXVIII. Much of this dodlrine may be admitted. The human body, upon many occafions, becomes preternaturally plethoric ; and the U 2 300 PRACTICE the dangerous confequences which might from thence be apprehended, feem to be obviated by an hemorrhagy taking place: and, further, the neceftity of hemorrhagy often appears from hence, that the fup- preflion of it feems to occafion many dis- orders. All this feems to be juft; but, in the conclufion drawn from it there is a fal- lacy. DCCLXXIX. It appears to me certain, that hemor- rhagy,' either upon its firft attack, or upon its after recurrence, is never neceftary to the health of the body, excepting upon the iuppofit on, that the plethoric Rate which feern to require the evacuation, cannot be otherwife prevented or removed ; and as I imagine it poflible by other means to prevent or remove a plethoric Plate, fo I do OF PHYSIC. 301 do not think that hemorrhagy is, in ail cafes, neceffary. In general, I am of opi- nion that hemorrhagy is to be avoided, i . Becaufe it dqes not always happen in parts where it is fafe. 2. Becaufe often, while it does relieve a plethoric ftate, it may, at the fame time, induce a very dangerous difeafe. 3. Becaufe it may often go to excefs, and either endanger life, or induce a dan- gerous infirmity. And, laftly, Becaufe it has a tendency to increafe the plethoric flate it was meant to relieve; to occafion its own recurrence, (DCCXXI.); and thereby to induce a ha- bit, which, if left to the precarious and unequal operation of nature, may, from the frequent errors of this, be attended with much danger. u 3 DCCLXXX. 302 PRACTICE DCCLXXX. It is further to be confidered, that he- morrhagies do not always arife from the neceflities of the fyftem, but often proceed from incidental caufes. It appears to me, that all hemorrhagies of the latter kind may be immediately fupprelfed, and the repetition of them, as it induces a plethora, and a habit not otherwife neceflary, may be prevented with great advantage. DCCLXXXL Upon the whole of this fubject, I con- clude, that every preternatural hemorrhagy, or, in other words, every one except that of the pienfes in females, is to be avoided, and cfpecially the returns of it prevented; and I therefore now proceed to mention, how hemorrhagy, and its recurrences, may, and Ihould be prevented. DCCLXXXII. OF PHYSIC. 303 DCCLXXXII. From the principles delivered above, it will immediately appear, that the preven- tion, either of the firft attacks, or of the returns of hemorrhagy, will chiefly, and in the firft place, depend upon the prevent- ing or removing any confiderable degree of a plethoric ftate which may happen to pre- vail in the body. It is true, that, where the hemorrhagy depends upon the parti- cular conformation of certain parts, rather than upon the general plethoric ftate of the whole ; the meafures for removing or preventing the latter, may not always be fuflicient for preventing hemorrhagy : but at the fame time it muft be evident, that determinations, inconfequence of the con- formation of particular parts, will always be urged more or lefs, in proportion to the greater or lefler degree of the plethoric ftate of the whole fyftem ; and, therefore, U 4 that, 304 PRACTICE that, even in the cafes depending upon particular conformation, the preventing or removing an unufually plethoric Rate, will always be a chief means of preventing he- inorrhagy. It is further to be attended to, that there may be feveral inequalities in the balance of the fyftem, which may have little or no effect unlefs when the fyftem becomes preternaturally plethoric ; and, therefore, that, in all cafes, the pre- venting or removing of the plethoric ftate of the fyftem, will be a chief means of pre- venting the firfl: attacks, or the returns of hemorrhagy. It now, therefore, remains to explain, how the plethoric ftate of the fyftem is to be prevented or removed. DCCLXXXHI. The fluids of the human body are in continual wafte by the excretions, but are commonly replaced by the aliments taken in; OF PHYSIC. 305 in; and if the quantity of aliments in any meafure exceed that of the excretions, an increafe of the quantity of the fluids of the body, or, in other words, a plethoric Rate, mu ft neceflarily arife. This, to a certain degree, is requifite for the growth of the body : but, even then, if the pro- portion of the aliments to the excretions, be greater than is fuited to the growth of the body, and more certainly ftill, if, after the growth is completed, when an equality between the ingejla and the excreta fliould be eftablifhed, the difproportion ftill con- tinue, a preternaturally-plethoric ftate mu ft arife. In both cafes, it is evident, that the plethora muft be prevented or corrctfted by adjufting theingefta and excreta to each other; which generally may be done, ei- ther by diminifliing the ingefta, or by in- creafing the excreta. The former may be eftecled by the management of diet, the 306 PRACTICE the latter by the management of exer- cife. DCCLXXXIV. The ingefta may be diminifhed, either by giving aliment in lefs quantity than ufual, or by giving aliments of a lefs nu- tritious quality ; that is, aliments of a fub- ftance, which, under the fame bulk and weight, contain lefs of a matter capable of being converted into animal fluids, and more of a matter ready to pafs off by the excretions, and confequently lefs of a matter to be retained and accumulated in the veffels. The choice of aliments fuited to thefe purpofes, mufl be left to be directed by the dodrines of the Materia Medica. DCCLXXXV. OF PHYSIC. 307 DCCLXXXV. The increafing of the excreta, and there- by diminifhing the plethoric date of the fydem, is to be obtained by increafing the exercife of the body ; and generally for ad- jufting the balance between the ingefta and excreta, and thereby obviating the plethoric date, it is neceflary that exercife, in a due meafure, be very condantly employed, DCCLXXXVI. The obferving abftinence, am} the em- ployment of exercife, for obviating or re- moving the plethoric ftate of the body, were formerly confidered pretty fully, when treating of the gout, (DXLVIII. to DLII.); fo that the lefs is necettary to be faid here : and it is now only requifite to obferve, that the fame doubts, as in cafes of the gout, do not occur here with regard to 308 PRACTICE to the fafety of thofe meafures, which, in a plethoric ftate of the body difpofing to hemorrhagy, are always admiilible and proper. Here, however, it is to be obfer- ved, that fame choice in the mode of exer- cife is neccflary, and that it fhould be dif- ferent according to the particular determi- nations which may happen to prevail in the fyftem. In general, in the cafe of ple- thora difpofing to hemorrhagy, bodily ex- ercife will always be hazardous, and gefta- tion more commonly fafe. DCCLXXXVII. Artificial evaluations may be employed to dimini fh the plethoric ftate of the body; and when, at any time, it has become con- fiderable, and immediately threatens a dif- eafe, thefe evacuations fhould be made to the quantity that the fymptoms fcem to re- quire. But it is conftantly to be attended to, OF PHYSIC. 309 to, that blood-lettings are improperly em- ployed to prevent a plethora, as they have a tendency to increafe it (DCCXXT.); and as they require to be often repeated, and are thereby apt to induce a habit which may be attended with much danger. DCCLXXXVIIL While a plethora, and thereby the pre- difpofition tohemorrhagy, is avoided, or re- moved, the other meafures nccefTary for preventing the occurrence of this, are thofe for avoiding the remote caufes. Thefe have been enumerated in (DCCLXXV.); and the means of avoiding them, fo far as within our power, are fufficiently obvious. DCCLXXXIX. Having thus mentioned the means of preventing either the firfl attacks, or the re- currence PRACTICE 310 currence of hemorrhagy ; I muft next fay how it is to be managed when it has actu- ally come on. DCCXC. When an hemorrhagy has come on which appears to have arifen from a preternatu- rally plethoric (late, or from fome change in the balance of the fanguiferous fyftem, no meafures are to be immediately taken for fupprefling it; as we may expert, that, when the quantity of blood neceflary for the relief of the fyftem is poured out, the effufion will fpontaneoufly ceafe. DCCXCI. In many cafes, however, it may be fuf- peCled, that the quantity of blood poured out, is not exatftly in proportion to the ne- ceflities of thefyftem, cither for relieving a general OF PHYSIC. 311 general plethora or a particular congeflion, but that it is often to a greater quantity than thefe require. This we fuppofe to happen in confequence of an inflammatory dia- thefls prevailing, and of a febrile fpafm be- ing formed; and therefore it is in many cafes proper, as well as for the moft part fafe, to moderate the evacuation, and, when it threatens to go to excefs, to fupprefs it altogether. DCCXCII. An hemorrhagy may be moderated by avoiding any irritation that might concur to increafe it; fo that every part of the an- tiphlogiftic regimen is to be obferved ; in particular external heat, both as it ratifies the fluids, and ftimulates the folids, is to be carefully avoided : and, it is probable, that in all cafes an hemorrhagy may be fafely 312 PRACTICE fafely moderated by cool air applied, and cold drink exhibited. DCCXCIIL A fecond means for the fame purpofe, is, the ufe of refrigerant medicines, and parti- cularly of acids and nitre. DCCXCIV. A third means which has been frequently employed, is that of blood-letting. Thd propriety of this pratflice may be doubt- ful, as the quantity of blood poured out by the hemorrhagy, may be fuppofed to an* fwer the purpofe of an evacuation in any other way; and I am ready to allow, that the practice has been often fuperfluous, and fometimes hurtful, by making a greater evacuation than was neceflary or fafe. At the fame time, I apprehend it is not for the mere OF PHYSIC. 313 mere purpofe of evacuating, that blood- letting is to be pradiifed in the cure of he- morrhagy; but that it is further neceflary for taking off the inflammatory diathefls which prevails, and the febrile fpafm that has been formed. Accordingly, in the cafe of hemorrhagy, when the pulfe is not only frequent, but quick and full, and does not become fofter or flower upon the flowing of the blood, and that the effufion is pro- fufe, and threatens to continue fo, it appears to me, that blood-letting may be neceflary, and I have often found it ufeful. It feems probable alfo, that the particular circum- ftances of venefedtion may render it more powerful for taking off the tenfion and in- flammatory irritation of the fyftem, than any gradual flow from an artery. DCCXCV. That a fpafm of the extreme veffels has Vol. IL X 9 314 PRACTICE a fhare in fupporting hemorrhagy, appears to me probable from hence, that blittering has been often found ufeful in moderating and fupprefling the difeafe. DCCXCVL Do emetics and vomiting contribute to the cure of hemorrhagy? See Dr Bryan Robinson on the virtues and power of medicines. DCCXCVII. When an hemorrhagy is very profufe, andfeems to endanger life, or even threatens to induce a dangerous infirmity, it is agreed on all hands, that it is to be immediately fupprefled by every means in our power ; and particularly, that, befides the means above mentioned for moderating the dif- eafe, aftringents, internal or external where the OF PHYSIC. 315 the latter can be applied, are to be employed for fupprelhng it. DCCXCVIII. The internal aftringents are either vege- table or foflil. The vegetable aftringents are feldom very powerful in the cure of any hemor- rhagica, except thofe of the alimentary ca- nal The foflil aftringents are more power- ful ; but fome choice amongft the diffe- rent kinds may be proper. The chalybeates, fo frequently employed, do not appear to me to be very powerful. The preparations of lead are certainly more fo, but are otherwife of fo pernicious a quality, that they fhould not be employed except in cafes of the utmoft danger. The Tindhira Sarurnina, or Antiphthifica, as it has been called, appears to be of little effi- cacy; X 2 316 PRACTICE cacy; but whether from thefmall portion of lead which it contains, or from the ftate in which the lead is in it, I am uncertain. The foffil aftringent that appears to me the moft powerful, and at the fame time the moft fafe, is alum. DCCXCIX. External aftringents, when they can be applied, are more effectual than the inter- nal. The choice of thefe is left to the fur- geons. DCQC. The moft powerful of all aftringents ap- pears to me to be cold, which may be em- ployed, either by applying cold water to the furface of the body, or by throwing it into the internal parts. DCCCI. OF PHYSIC. 317 DCCCL For fupprefling hemorrhagies, many fu- perftitious remedies and charms have been recommended, and pretended to have been employed with fuccefs. The feeming fuc- cefs of thefe, however, has been generally owing to the by-(landers miftaking a fpon- taneous ceafing of the hemorrhagy for the effedl of the remedy. At the fame time, I believe, that thofe remedies may have been fometimes ufeful, by impreHing the mind with horror, awe, or dread. DCCCII. Upon occafion of profufe hemorrhagies, opiates havp been employed with advan- tage ; and, when the fulnefs and inflam- matory diathefis of the fyftem have been previoufly taken off by the hemorrhagy X 3 itfelfj 318 PRACTICE itfeif, or by blood-letting, 1 think opiates may be employed with faiety. Dcccni. For reftraining hemorrhagy, ligatures have been applied upon the limbs, in the view of retarding the return of the venous blood from the extremities ; but they ap- pear to me to be of uncertain and ambi- guous ufe. DCCCIV. In the cafe of profufe hemorrhagies, no pains are to be taken to prevent a Deli- quium Animi, or fainting, as the happen- ing of this is often rhe moft certain means of Hopping the hemorrhagy. DCCCV. OF PHYSIC. 319 DCCCV. Having thus delivered the general doc- trine of hemorrhagy, I proceed to confider the particular cafes of it. It may perhaps be remarked, that I have marked fewer of thefe than are commonly enumerated by the nofologifts ; but my reafons for differ- ing from thefe authors, muft be left to a nofological difcuflion, to be entered into elfewhere more properly than here. X 4 CHAP. 320 PRACTICE CHAP. n. Of the Epistaxis, or Hemorrhagy of the Nose. DCCCVI. THE ftate of the veflels upon the in- ternal furface of the nofe being fuch as already mentioned (DCCLVIL), renders an hemorrhagy from that, more frequent than from any other part of the body. DCCCVII. OF PHYSIC. 321 DCCCV1L The blood commonly flows from one noftril only, and probably becaufe an he* morrhagy from one veflel relieves the con* geftion in all the neighbouring veflels. The blood flowing from both noftrils at the fame time, fliows commonly a more confiderable difeafe. DCCCVIIL This hemorrhagy happens to perfons of every eonftitution and temperament, but moft frequently to thofe of a plethoric ha- bit, and fanguine temperament. It hap- pens to both fexes, but moft frequently to the male. DCCCIX. This hemorrhagy may occur at any time of 322 PRACTICE of life; but moft commonly happens to young perfons, owing to the ftate of the balance of the fyftem peculiar to that age, as mentioned in (DCCLVL) DCCCX. Although generally it happens to perfons before they have arrived at their full growth, and more rarely afterwards; yet fometimes it happens to perfons after their acme, and during the Rate of manhood: and it muR be imputed to an un- ufually plethoric Rate of the fyRem ; to an habitual determination of the blood to the veffels of the nofe; or to the particular weaknefs of thefe. DCCCXI In all thefe cafes the difeafe may be con- fidered as an hemorrhagy purely arterial, and OF PHYSIC. 323 and depending upon an arterial plethora; but it fometimes occurs in the decline of life, when probably it depends upon and may be confldered as a mark of a venous plethora of the veflels of the head. See (DCCLXX11.) DCCCXII. This hemorrhagy happens alfb at any period of life, in certain febrile difeafes, which are altogether or partly of an in- flammatory nature, and which (how a par- ticular determination of the blood to the veflels of the head. Thefe difeafes often admit of a folution by this hemorrhagy, when it may be properly termed critical. DCCCXIII. The difeafe fometimes comes on with- out any previous fymptoms; particularly, when 324 PRACTICE when fome external violence has a fliare in. producing it. But, when it proceeds en- tirely from an internal caufe, it is com- monly preceded by headachs, rednefs of the eyes, a florid colour of the face, an un- ufual pulfation in the temples, a fenfe of fulnefs about the nofe, and an itching of the noflrils. A bound belly, pale urine, coldnefs of the feet, and cold fliivering over the whole body, are alfo fometimes among the fymptoms that precede the difeafe. DCCCXIV. From the weaknefs of the veffels of the nofe, the blood often flows from them with- out any confiderable effort of the whole fyf- tem, and therefore without any obfervable febrile diforder ; which, however, in many cafes, is, in all its circumflances, very dis- cernible. DCCCXVe OF PHYSIC. 325 DCCCXV. An hemorrhagy of the nofe happening to young perfons, is, and may generally be, confidered as a flight difeafc of little confe- quence, and hardly requiring any remedy. But, even in young perfons, when it recurs very frequently, and is very copious, it will require particular attention, as it is to be confidered as a mark of arterial plethora; and, as frequently returning, it may in- creafe the plethoric ftate_; which, in a more advanced flage of life, may give the blood a determination to parts from which the hemorrhagy would be more dangerous. All this will more particularly require at- tention, according as the marks of plethora, and of particular congeftion, preceding the hemorrhagy, are mote confiderable; and as the flowing of the blood is attended with a more confiderable degree of febrile dif- erder. DCCCXVL 326 PRACTICE DCCCXVL When the epiflaxis happens to perfons after their acme, returning frequently, and flowing copioufly, it is always to be confi- dered as a dangerous difeafe, and as more certainly threatening the confequences men- tioned in the laft paragraph. DCCCXVII. When this hemorrhagy happens in the decline of life, it may be confidered as in itfelf very falutary : but at the fame time, it is to be confidered as a mark of a very dang rous ftate of the fyftem ; that is, as a mark of a very ftrong tendency to a ve- nous plethora in the veffels of the head: and I have accordingly obferved it often followed by apoplexy, palfy, or fuch like difeafes. DCCCXVIII. OF PHYSIC. 327 DCCCXVIIL When an hemorrhagy from the nofe happens in febrile difeafes, as mentioned in (DCCCXIL), and is in pretty large quan- tity, it may be confidered as critical and falutary ; but it is very apt to be profufe, and even in this way dangerous. It upon fome occafions occurs during the eruptive fever of feveral exanthemata, and is in fuch cafes fometimes falutary; but, if thefe exanthemata be accompanied with any putrid tendency, this hemorrhagy, like artificial blood-lettings, may have very bad efle*ds. DCCCXIX. Having thus explained the feveral cir- cumftances of epiftaxis, I proceed to con- fider the management and cure of it. I ufe the expreflion of management, becaufe it has been PRACTICE 328 been ufually thought to require no cure$ but that nature fhould be allowed to throw out blood in this way very frequently ; and as often as it appears to arife from in- ternal caufes, that is, from a ftate of the fyftem fuppofed to require fuch evacua- tion. DCCCXX. I am however of opinion, for the reafons given in (DCCLXXIX.), that this difeafe is very feldom to be left to the conduct of nature; and that in all cafes it fhould be moderated by keeping the patient in cool air ; by giving cold drink; by keeping the body and head eredl; by avoiding any blowing of the nofe, fpeaking, or other ir- ritation: and, when the blood has flowed for feme time, without fhowing any ten- dency to ceafe, a profufe bleeding is to be prevented by meafures employed to flop it, fuch OF PHYSIC. 329 fuch as prefiingthe noftril from which the blood flows, wafliing the face with cold water, or applying this to other parts of the body. DCCCXXI. Even in the cafe of young perfons where the difeafe is leaft hazardous, and even in the fir ft attacks, I judge fuch meafures to be proper : but they will be ftill more proper if the difeafe frequently recurs without any external violence ; if the returns fhall happen to perfons of a habit difpofed to be plethoric; and, more particularly, if the marks of a plethoric ftate appear in the pre- cedent fymptoms. (DCCCXIII.). DCCCXXII. Even in young perfons, if the bleeding be very profufe and long continued, and Vol. II. Y more 330 PRACTICE more efpecially if the pulfe become weak and the face pale, I apprehend it will be proper to fupprefs the hemorrhagy by every means in our power. See DCCXCV1I. and following paragraphs. DCCCXXIII. Further, in the fame cafe of young perfons, when the returns of this hemorrhagy become frequent, and efpecially with the marks of a plethoric habit, I think it necelfary to employ fuch a regimen as may prevent a plethoric Hate, (DCCLXXXlil.- DCCLXXXVII.). At the fame time, care fhould be taken to avoid all circumftances which may deter- mine the blood more fully to the veffels of the head, or prevent its free return from them ; and, by keeping an open belly, to make fome derivation from them. DCCCXXIV, OF PHYSIC. 331 DCCCXXIV. In adult perfons, liable to frequent returns of/ the epiftaxis, the whole of the meafures propofed (DCCCXXlIi ), are more certainly and freely to be em- ployed. When, with the circumftances mentioned in DCCCXIII. the tendency to a profufe hemorrhagy appears, a bleeding at the arm may be proper, even in young perfons ; but, in the cafe of adults, it will be ftill more allowable, and even necelfary. DCCCXXV. In perfons of any age liable to frequent returns of this hemorrhagy, when the mea- fures propofed in DCCCXVII. tefeq. {hall have been neglected, or, from peculiar cir- cumftancesin the balance of the fyftem, fhall have proved ineffectual, and the fymptoms threatening hemorrhagy (DCCCXXXV III.) Ya fljall PRACTICE 332 fliall appear, it will then be proper, by blood- letting, cooling purgatives, and every part of the antiphlogiftic regimen, to prevent the hemorrhagy, or at leaft to prevent its be- ing profufe when it does happen. DCCCXXVL In the circumftances juft now mentioned (DCCCXXV.), the meafures propofed are proper, and even neceffary ; but it ihould at the fame time be obferved, that thefe arepradtifed with much lefs advantage than thofe pointed out in DCCCXXIV. : be- caufe, though thofe fuggefted here may prevent the coming on of the hemorrhagy for the prefent, they certainly however difpofe to the return of that plethoric ftate which required their being ufed, and there can be no proper fecurity againft returns of the difeafe, but by purfuing the means propofed in DCCCXXIII. Dcccxxvir. OF PHYSIC. 333 DCCCXXVIL When the hemorrhagy of the nofe hap- pens to perfons approaching to their full growth, and when its returns have been preceded by the fymptoms DCCCXIII. it may be fuppofed, that, if the returns can be prevented by the mcafures propofed in DCCCXXV. thefe may be fafely em- ployed ; as the plethoric Rate induced will be rendered fafe, by the change which is foon to take place in the balance of the fyf- tem. This, however, cannot be admitted; as the evacuations praftifed upon this plan will have all the confequences which, I have already obferved, may follow the recurrence of the hemorrhagy itfelf. DCCCXXVIIL When the hemorrhagy of the nofe {hall be found to make its returns at nearly Y3 Hated 334 PRACTICE ftated periods, the meafures for preventing it (DCCCXXV.) may be pra6tifed with greater certainty ; and, upon every repe- tition of blood-letting, by dimini£hing the quantity taken away, its tendency to in- duce a plethora may be in fome meafure avoided. When, indeed, the repetition of evacuations is truly unavoidable, the dimi- nilhing them upon every repetition is pro- perly pradlifed : but it is a practice of nice and precarious management, and fhould by no means be trufted to, fo far as to fuper- fede the meafures propofed in DCCCXXV. wherever thefe can be admitted. DCCCXXIX. When the hemorrhagy of the nofe happens in confequence of a venous ple- thora in the veflels of the head, as in DCCLXXII. the flowing of the blood pretty largely may be allowed, efpecially wheq OF PHYSIC. 335 when it happens after the fuppreflion or ceafing of the menftrual or hemorrhoidal flux. But, though the flowing of the blood is, on its firft occurring, to be allowed, there is nothing more proper than guard- ing againfl its returns. This is to be done not only by the meafures propofed in DCCLXXX1II etfeq. but, as the effects ofa plethoric ftate of the veflels of the head are very uncertain, fo, upon any appearance of it, and efpecially upon any threatening of hemorrhagy, the plethora is to be removed, and the hemorrhagy to be obviated imme- diately by proper evacuations ; as blood- letting, purging, and iflues, or by reftoring fupprefled evacuations, where this can be done. CHAP. 336 PRACTICE CHAP. III. Of the Hemoptysis, or Hemorrhagy from the Lungs. SECT. I. Of tbeV henomen a DCCCXXX. w HEN, after fome affection of the breaft, blood is thrown out from the mouth, and is brought out with more or lefs of coughing, there can be no doubt that OF PH Y S I C. 337 that it comes from the lungs; and this ge- nerally afcertains the difeafe of which I am now to treat. But there are cafes in which the fource of the blood fpit out is uncertain; and therefore, fome other con- fiderations to be mentioned hereafter, are often neceflary to afcertain the exiftence of an hemoptyfis. DCCGXXXI. The blood-veffels of the lungs are more numerous than thofe of any other part of the body of the fame bulk. Thefe veffels, of the larged fize, as they arife from the heart, are more immediately than in any other part fubdivided into veffels of the fmalleft fize; and thefe fmall veffels fpread out near to the internal furfaces of the bronchial cavities, are iituated in a loofe cellular texture, and covered by a tender membrane only : fo that, conlidering how readily 338 PRACTICE readily and frequently thefe veflels arc gorged with blood, we may underftand why an hemorrhagy from them is, next to that of the nofe, the moft frequent of any; and particularly, why any violent fhock given to the whole body fo readily occa- fions an hemoptyfis. DCCCXXXII. An hemoptyfis may be occafioned by external violence, at any period of life; and I have explained above (DCCLX ), why in adult perfons, while the arterial ple- thora ftill prevails in the fyftem, that is, from the age of fixteen to that of five-and- thirty, an hemopty(is may at any time be produced, merely by a plethoric Hate of the lungs. DCCCXXX1II. O F P H Y S I C. 339 DCCCXXXIII. But it has been alfo obferved above, (DCCLX1.), that an hemoptyfis more fre- quently arifes from a faulty proportion between the capacity of the veffels of the lungs and that of thofe of the reft of the body. Accordingly it is often a heredi- tary difeafe, which implies a peculiar and faulty conformation. And the dif afealfo happens efpecially to perfons whodifeover the fmaller capacity of their lungs, by the narrownefs of their cheft, and by the pro- minency of their Ihoulders; which laft is a mark of their having been long liable to $ difficult refpiration. DCCCXXXIV. With thefe circumftances alfo the dif- cafe happens efpecially to perfons of a fan- guine temperament; in whom particularly, the 340 PRACTICE the arterial plethora prevails. It happens likewife to perfons of a (lender delicate make, of which a long neck is a mark; to perfons of much fenfibility, and irritabi- lity, and therefore of quick parts, whole bodies are generally of a delicate ftruclure; to perfons who have been formerly liable to frequent hemorrhagies of the nofe ; to perfons who have buffered a fuppreflion of any hemorrhagy they had formerly been liable to, the moft frequent inftance of which is in females who have buffered a bupprellion of their menftrual flux ; and, laftly, to perfons who have buffered the am- putation of any considerable limb. DCCCXXXV. Ill moft of thebe cafes (DCCCXXXIV.), the difeafe happens efpecially to perfons about the time of their coming to their full OF PHYSIC. 341 full growth, or foon after it, and this for the reafons fully fet forth above. DCCCXXXVI. From all that has been faid from DCCCXXXI. to DCCCXXXV. the pre- difponent caufe of hemoptyfis will be Suf- ficiently underftood, and the difeafe may happen from the mere-circumllance of the predifponent caufe arifing to a confider- able degree. In the predifpofed, however, it is often brought on by the concurrence of various occasional and exciting caufes. One of thefe, and perhaps a frequent one, is external heat; which, even when in no great degree, will bring on the difeafe in fpring, and the beginning of fummer, while the heat rarities the blood more than it relaxes the folids which had been before contracted by the cold of winter. Ano- ther exciting caufe is a fudden diminution of PRACTICE 342 of the weight of the atmofphere, efpecially when concurring with any effort in bodily exercife. This effort, too, alone, may of- ten, in the predifpofed, be the exciting caufe ; and, more particularly, any vio- lent exercife of refpiration. In fhort, in the predifpofed, any degree of external violence alfo may bring on the difeafe. DCCCXXXVII. Occafioned by one or other of thefe caufes (DCCCXXXVI.), the difeafe comes on with a fenfe of weight and anxiety in the cheft, fome unealinefs in breathing, fome pain of the bread or other parts of the thorax, and fome fenfe of heat under the fternum; and very often, before the difeafe appears, a faltilh tafle is perceived in the mouth. DCCCXXXVIII. OF PHYSIC. 343 DCCCXXXV1IL Immediately before the appearance of blood, a degree of irritation is felt at the top of the larynx. To relieve this, a hawk- ing is made, which brings up a little blood, of a florid colour, and fomewhat frothy. The irritation returns ; and, in the lame manner, more blood of a like kind is brought up, with fome noife in the wind- pipe, as of air palling through a fluid. DCCCXXXIX. This is commonly the manner in which the hemoptyfls begins ; but lometimes at the very firft the blood comes up by coughing, or at leaft fomewhat of cough- ing accompanies the hawking juft now mentioned. DCCCXL. 344 P R A C T 1 C E DCCCXL. The blood iffuing is fometimes at firfl in very fmall quantity, and foon difappears altogether: but, in other cafes, efpecially when it repeatedly occurs, it is in greater quantity, and frequently continues to ap- pear at times for feveral days together. It is fometimes profufe; but rarely in fuch quantity as either by its excefs, or by its fudden fuffocation, to prove immediately mortal. It commonly cither ceafes fpon- taneoufly, or is flopped by the remedies employed. DCCCXLI. When blood is thrown out from the mouth, it is not always cafy to determine from what internal part it proceeds; whe- ther from the internal fur face of the mouth itfelf, from the fauces, or adjoining cavi- ties OF PHYSIC. 345 ties of the nofe, from the ftomach, or from the lungs. It is, however, very neceffary to diftinguilh the different cafes; and, in molt inftances, it may be done by attend- ing to the following confiderations. DCCCXLII. When the blood fpit out, proceeds from fome part of the internal iurface of the mouth itfelf, it comes out without any hawking or coughing ; and generally, up- on infpedlion, the particular fource of it becomes evident. DCCCXLIII. When blood proceeds from the fauces, or adjoining cavities of the nofe, jt may be brought out by hawking, andfometimes by coughing, in the manner we have defcribed in DCCCXXXVIL and DCCCXXXIX.; Vol. II. 2 fo 346 PRACTICE fo that, in this way, a doubt may arife concerning its real fource. A patient of- ten lays hold of thele circumftances to pleafe himfelf with the opinion of its co- ming from the fauces, and he may be al- lowed1 to do fo : but a phyfician cannot readily be deceived, if he conlider, that a bleeding from the fauces is more rare than one from the lungs ; that the former fel- dom happens but to perfons who have been before liable either to an hemorrhagy of the nofe, or to fome evident caufe of erofion ; and, in moft cafes, by looking into the fauces, the diflillation of the blood, if it comes from thence, will be perceived. DCCCXLIV. When blood proceeds from the lungs, the manner in which it is brought up will commonly fhow from whence it comes : but, independent of that, there are many circum- OF PHYSIC. 347 tircumftances which may concur to point it out, fuch as the period of life, the habit of body, and other marks of a predifpofition (DCCCXXXIII - DCCCXXXV.) ; and, together with thefe, the occafional caufes (DCCCXXXVI.) having been immediately before applied* DCCCXLV. When vomiting accompanies the throw- ing out of blood from the mouth, as vo- miting and coughing often mutually ex- cite each other; fo they may be frequently joined, and render it doubtful, whether the blood thrown out proceeds from the lungs or from the ftomach. We may however generally decide, by considering, that blood does not fo frequently proceed from the Stomach as from the lungs: that blood proceeding from the Stomach com- monly appears in greater quantity, than Z 2 when 348 PRACTICE when it proceeds from the lungs: that the! blood proceeding from the lungs is ufually of a florid colour, and mixed with a little frothy mucus only ; whereas the blood from the ftomach is commonly of a darker colour, more grumous, and mixed with the other contents of the ftomach : that the coughing or vomiting, according as the onfe or the other firft arifes in the cafes in which they are afterwards joined, may fometimes point out the fource of the blood; and, laftly, that much may be learned from the circumftances and fymp- toms which have preceded the hemor- rhagy. Thofe which precede the hemoptyfis, enumerated in DCCCXXXVI1. are moft of them evident marks of an affection of the lungs. And, on the other hand, the he- matemefis, or ifluing of blood from the ftomach, has alfo its peculiar fymptoms and circumftances preceding it; as, for inftance, OF PHYSIC. 349 inftance, fome morbid affection of this organ, or at lead fome pain, anxiety, and fenfe of weight, referred difcinclly to the region of the ftomach. To all this may be added, that the vomiting of blood hap- pens more frequently to females than to males ; and to the former, in confequence of a fuppreflion of their menftrual flux : and, by attending to all thefe conlide- rations (DCCCXLII.-DCCCXLV.), the prefence of the hemoptyfls may commonly be fufficiently afcertained. Z 3 SECT. 350 PRACTICE SECT. II. Of the Cure of Hemoptysis. DCCCXLVI. This difeafe is fometimes attended with little danger; as, when it happens to fe- males in confequence of a fuppreflion of the menfes ; when, without any marks of a predifpofition, it arifes from external violence; or when, from whatever caufe arifing, it leaves behind it no cough, dyfp- OF PHYSIC. 351 dyfpnoea, cr other afFedlion of the lungs. Even in fuch cafes, however, a danger may arife from too large an wound being made in the velTels of the lungs ; from a quantity of red blood being left to flag- nate in the cavity of the bronchia ; and particularly, from any determination of the blood being made into the veflels of the lungs, which, by renewing the hemor- rhagy, may have dangerous confequences. In every infiance therefore of hemoptyfis, the effufion is to be moderated by the fe- veral means mentioned (DCCXC1I, to DCCXCV). DCCCXLVII. Thefe meafures are efpecially neceflary when the hemoptylis arifes in confequence of predifpofition; and in all cafes where there is the appearance of a large effufion, or where the hemorrhagy frequently re- turns, 1 4 352 PRACTICE turns, the effufion is not only to be mode- rated, but to be entirely flopped, and the returns of it prevented by every means in our power. See DCCXGV1L and follow* ing. DCCCXLVIII. To flop an liemoptyfis, or prevent the returns of it, two medicines have been fre- quently employed; neither of which I can approve of. Thefe are, chalybeates, and the Peruvian bark. As both of them con- tribute to increafe the phlogiftic diathefis of the fyflem, they can hardly be fafe in any cafe of adlive hemorrhagy, and I have frequently found them hurtful. DCCCXLIX. As the hemoptyfis which happens in confequence of prechfpofition, is always attended OF PHYSIC. 353 attended with a phlogiftic diathefis; and, as the bad confequences of the difeafe are efpecially to be apprehended from the con- tinuance of that diathefis; fo this is to be induftrioully taken off by blood-letting, in greater or fmaller quantity, and more or Jefs frequently repeated, according as the fymptoms fhall direct. At the fame time, cooling purgatives are to be employed, and every part of the antiphlogiftic regi- men is to be ftriclly enjoined. The refri- gerants may alfo be adminiftered; taking care, however, that the acids, and more efpecially the nitre, do not excite cough- ing. DCCCL. From what was obferved in DCCXCV. it will appear, that bliftering upon the bread or back may be a remedy of he- paopty/is, when it is prefent; and that if- fues 354 PRACTICE fues in the fame places may be ufeful in preventing the recurrence of it when it has ceafed. DCCCLL The avoiding of motion is generally a proper part of the antiphlogiftic regimen; and, in the hemoptyfis, nothing is more necelfary than avoiding bodily exercife: but fome kinds of geftation, as failing, and travelling in an eafy carriage on fmooth roads, have often proved a re- medy. DCCCLIL Such is the treatment I can propofe for the hemoptyfis, confidered merely as an hemorrhagy: But when, in fpite of all our precautions, it continues to recur, it is often followed by an ulceration of the lungs, and a OF PHYSIC. 355 a phthilis pulmonalis. This, therefore, I muft now proceed to conlider; but, as it arifes alfo from other cauies belides the he- moptyfis, it mull be treated of with a more general view. CHAP. 356 PRACTICE CHAP. IV. Of the Phthisis Pulmonalis, or Consumption of the Lungs. SECT. I. Of the Phenomena and Causes of Phthisis Pulmonalis. DCCCLIII. r A 5HE Phthifis Pulmonalis I would de- fine to be, An expectoration of pus or purulent matter from the lungs, attended with a hectic fever. As O F P H Y S I C, 357 As this is the principal fpecies of phthifis, I fhall frequently in this chapter employ the general term of phthifis, though flriCtly meaning the phthifis pulmonalis. DCCCLIV. I have met with fome infiances of an expectoration of purulent matter, conti- nuing for many years, accompanied with very few fymptoms of heCtic, and at lead without any hedtic exquifitely formed: but, in none of thefe inftances, were the perfons fo entirely free from fymptoms of hectic, as to form any exception to the ge- neral definition. DCCCLV. In every inftance of an expectoration of pus, I prefbme there is an ulceration of the lungs. The late Mr de Haen is the only 358 PRACTICE only author that I know of who has ad- vanced another opinion, and has fuppofed, that pus may be formed in the blood-vef- fels, and be from thence poured into the bronchise. Admitting his fact, I have at- tempted an explanation of the appearance of pus without ulceration in CCCXLIX.: but, after all, I cannot help fufpeRing the accuracy of his obfervations; muR entirely reject his explanation of them ; muft how- ever allow, that we Rill want facts to fup- port the explanation I have offered; and doubt much if it will apply to any cafe of phthifis. For thefe reafons I Rill conclude, agreeably to the faith of all other diffec- tions, and the opinions of all phyiicians, that the fymptoms mentioned in our definition depend always upon an ulceration formed in the lungs. DCCCLVI. OF PHYSIC. 359 DCCCLVI. It has fometimes happened, that a ca- tarrh was attended with an expectoration of a matter fo much refembling pus, that phyficians have been often uncertain whe- ther it was mucus or pus, and therefore whether the difeafe was a catarrh or a phthifis. It is often of confequence to de- termine thefe queftions; and it appears to me that it may be generally done, with fuf- ficient certainty, from the following confi- derations, of which each particular is not always fingly decifive, but when they are taken together can hardly deceive us. i. From the colour of the matter; as mu- cus is naturally tranfparent, and pus al- ways opake. When mucus becomes opake, as it fometimes does, it becomes white, yellow, or greenilh; but the laft men- tioned colour is hardly ever fo remarkable in mucus as in pus. 2. From 360 PRACTICE 2. From the confidence; as mucus is more vifcid, and coherent, and pus lefs fix and may be faid to be more friable. When mucus is thrown into water, it is not rea- dily diffufed. but remains united in uni- form and circular mafles : but pus, in the fame circumftances, though not readily dif- fufed, does not remain fo uniformly uni- ted, and by a little agitation is broken in- to ragged fragments. 3. From the odour; which is feldom per- ceived in mucus, but frequently in pus. It has been propofed to try the odour of the matter expectorated, by throwing it upon live coals : but in fuch a trial both mucus and pus give otlt a difagreeable fmell, and it is not eafy to diftinguifli be- tween them. 4. From the fpecific gravity compared with water; and, indeed, it is ufual for the mucus of the lungs to fwim on the furface of water, and for pus to link in it. But in this OF PHYSIC. 361 this we may fometimes be deceived ; as pus which has entangled a great deal of air may fwim, and mucus that is free from air may link. 5. From the mixture which is difcernible in the matter brought up: for if a yellow or greenilh matter appears furrounded with a quantity of tranfparent or lefs opake and lefs coloured matter, the more ftrongly co- loured matter may be generally conlldered as pus ; as it is not eafy to underhand how one portion of the mucus of the lungs can be very conliderably changed, while the reft of it is very little fo, or remains in its ordinary ftate. 6. From the admixture of certain fub- ftances with the matter thrown out from the lungs. To this purpofe we are in- formed by the experiments of the late Mr Charles Darwin : a. That the vitriolic acid diflblves both mucus and pus, but moll readily the former: That, if water be added Vol. II. A a t© 362 PRACTICE to fuch a folution of mucus, this is fepa- rated, and either fwims on the furface, or, divided into flocculi, is fiifpended in the li- quor; whereas, when water is added to a like folution of pus, this falls to the bottom, or by agitation is diflu fed fo as to exhibit an uniformly turbid liquor, b. That a folu- tion of the cauflic fixed alkali, after fome time, diflblves mucus, and generally pus ; and, if water be added to fuch folutions, the pus is precipitated, but the mucus is not. From fuch experiments it is fuppofed, that pus and mucus may be certainly diftin- guifhed from each other. 7. From the expectoration's being at- tended with a hectic fever. A catarrh, or expectoration of mucus, is often attended with fever ; but never, fo far as 1 have ob- ferved, with fuch a fever as I am prefently to defcribe as a hectic. This, in my opi- nion, is the moft certain mark of a puru- lent Rate in ibme part of the body ; and if others OF PHYSIC. 363 others have thought differently, I am per- fuaded that it has been owing to this, that, prefumingupon the mortal nature of a con- firmed or purulent phthilis, they have con- lidered every cafe in which a recovery hap- pened, as a catarrh only: but, that they may have been miftaken in this, fliall be fhown hereafter. DCCCLVII. Having thus confidered the firft part of the character of the phrhifis pulmonalis as a mark of an ulceration of the lungs ; and having juft now faid, that the other part of the character, that is, the hecftic fever, is a mark or indication of the fame thing ; it is proper now to confider this here, as 1 had with that view omitted it before (LXX1V.). A a 2 DCCCLVIII, 364 PRACTICE DCCCLV11I. A heciic fever has the form of a remit- tent, which has exacerbations twice every day. The firft of thefe occurs about noon, fometimes a little fooner or later ; aqd a flight remiffion of it happens about five af- ternoon. This laft is foon fucceeded by an- other exacerbation, gradually increafing till after midnight: but after two o'clock of the morning, a remiffion takes place, which be- comes more and more confiderable as the morning advances. The exacerbations are frequently attended with fome degree of cold fhivering; or at leaft, the patient is exceedingly fenfible to any coolnefs of the air, feeks external heat, and often complains of a fenfe of cold, when, to the thermome- ter, his fkin is preternaturally warm. Of thefe exacerbations, that of the evening is always the moft confiderable. DCCCLIX. OF PHYSIC. 365 DCCCLIX* It has commonly been given as a part of the character of a hetflic fever, that an exacerbation of it commonly appears after the taking food 5 and it is true that dinner, which is taken at noon or after it, does feem to occafion fome exacerbation. But this muft not make us judge the mid-day exacerbation to be the effect of eating only; for I have often obferved it to come on an hour before noon, and often fome hours before dinner; which, in this country at prefent, is not taken till fome time after noon. It is indeed to be obferved, that in ahnoft every perfon, the taking food occa- fions fome degree of fever: but I am per- fuaded this would not appear fo coniider- able in a hediic, were it not that an exacer- bation of fever is prefent from another caufe; and accordingly, the taking food in the morning has hardly any fenfible effcdl. A a 3 DCCCLX. 366 PRACTICE DCCCLX. I have thus defcribed the general form of he&ic fever ; but many circumftances attending it, are further to be taken notice of. The fever I have defcribed does not com- monly fubfift long, till the evening exacer- bations become attended with fweatings; which continue to recur, and to prove more and more profufe, through the whole courfe of the difeafe. * Almoft from the firft appearance .of the heftic, the urine is high-coloured, and de- pofits a copious branny red fediment, which hardly ever falls clofe to the bottom of the veflel. In the hectic, the appetite for food is ge- nerally lefs impaired than in any other kind of fever. The thirft is feldom confiderable; the ptouth is commonly moift ; and as the dif- eafe OF PHYSIC. 367 eafe advances, the tongue becomes free from all fur, appears very clean; and in the ad- vanced Rages of the difeafe, the tongue nd fauces appear to be fomewhat inflamed, and become more or lefs covered with aphthae. As the difeafe advances, the red veflels of the adnata of the eye difappear, and the whole of the adnata becomes of a pearly white. The face is commonly pale; but, during the exacerbations, a florid red, and an al- moft circumfcribed fpot, appear on each cheek. For fome time, in the courfe of a hec- tic, the belly is bound ; but, in the advan- ced ftages of it, a diarrhoea almoft alwtys comes on, and continues to recur frequent- ly during the reft of the difeafe, alternating in fome meafure with the fweatings men- tioned The difeafe is always attended with a A a 4 de* 368 PRACTICE debility, which gradually increafes during the courfe of it. During the fame courfe an emaciation takes place, and goes to a greater degree than in almoft any other cafe. The falling off of the hairs, and the adunque form of the nails, are alfo fymp- toms of the want of nourilhment. Towards the end of the difeafe, the feet are often affedled with oedeinatous fwell- ings. The exacerbations of the fever are feldom attended with any headach, and fcarcely ever with delirium. The fenfes and judgment commonly re- main entire to the very end of the difeafe; and the mind, for the moft part, is confi- dent and full of hope. Somedays beforedeath, adelirium comes qn5 and commonly continues to the end. DCCCLXI. OF PHYSIC. 369 DCCCLXL The hectic fever now defcribed (DCCCL VIII, DCCCLX.) as accompanying a purulent ftate of the lungs, is perhaps the cafe in which it moft frequently appears : but I have never feen it in any cafe, when there was not evidently,or when I had not ground to fuppofe, there was a permanent puru- lency or ulceration in fome external or in- ternal part. It was for this reafon that in LXXIV. I concluded it to be a fympto- matic fever only. Indeed, it appears to me to be always the effect of an acrimony abforbed from abfceifes or ulcers, although it is not equally the effect of every fort of acrimony ; for the fcorbutic and cancerous kinds often fubfift long in the body with- out producing a hedlic. What is the pre- cife ftate of the acrimony producing this I cannot determine, but it feeins to be that of a vitiated purulency. DCCCLXIL 370 PRACTICE DCCCLXII. However this may be, it appears, that the hectic's depending in general upon an acrimony, explains its peculiar circum- ftances. The febrile Rate feems to be chiefly an exacerbation of that frequency of the pulfe, which occurs twice every day to perfons in health, and may be produced by acrimony alone. Thefe exacerbations, indeed, do not happen without the proper circumftances of pyrexia; but the fpafm of the extreme veflels in a hedlic does not feem to be fo confiderable as in other fevers : and hence the Rate of fweat and urine which appears fo early and fo conftantly in hectics. Upon the fame fuppofition of an acrimony corrupting the fluids, and debili- tating the moving powers, I think that X moft of the other fymptoms may alfo be explained. DCCCLXIII. OF PHYSIC. 371 DCCCLXIIL Having thus confidered the charaCteri- ftical fymptoms and chief part of the proxi- mate caufe of the phthifis pulmonalis, I proceed to obferve, that an ulcer of the lungs, and its concomitant circumftance of hedlic fever, may arife from different pre- vious affections of the lungs: all of which however may, in my opinion, be referred to five heads; that is, I. To an hemopty fis; 2. To a fuppuration of the lungs in con- fequence of pneumonia ; 3. To catarrh ; 4. To aflhma; or, 5. To a tubercle. Thefe feveral affeCtions, as caufes of ul- cers, fliall now be confidered in the order mentioned. DCCCLXIV. It has been commonly iuppofed, that an hemoptyfis was naturally, and almoft ne- ceflarily 372 PRACTICE ceftarily, followed by an ulcer of the lungs; but I will prefume to fay, that, in general, this is a miftake; for there have been many inftances of hemoptyiis occafioned by external violence, without being fol- lowed by any ulcer of the lungs ; and there have alfo been many inftances of hemop- tyiis from an internal caufe, without any confequent ulceration. And this too has been the cafe, not only when the hemop- tyiis happened to young perfons, and re- curred for feveral times, but when it has often recurred during the courfe of a long life. It is indeed eafy to conceive, that a rupture of the veftels of the lungs, like that of the veftels of the nofe, may be of- ten healed, as the furgeons fpeak, by the firft intention. It is probable therefore, that it is an hemoptyiis in particular cir- cumftances only, which is neceftarily fol- lowed by an ulcer ; but what thefe cir- cumftances are, it is difficulty determine. It OF PHYSIC. 373 It is poflible, that merely the degree of rupture, or frequently repeated rupture preventing the wound from healing by the firft intention, may occafion an ulcer ; or it is poflible that red blood eflufed, and not brought up entirely by coughing, may, by ftagnating in the bronchiae, become acrid, and erode the parts. Thefe how- ever are but fuppofitions, not fupported by any clear evidence. And, if we confider that thofe cafes of hemoptyfis which fol- low the predifpofition (DCCCXXXI1.- DCCCXXXV.) are thofe efpecially which end in phthifis, we fliall be led to fufpect •that there are fome other circumftances which concur here to determine the con- fequence of hemoptyfis, as I fliall here- after endeavour to ihow. DCCCLXV. Any fuppofition, however, which we can make 374 PRACTICE make with refpecl to the innocence of an hemoptyfis, muft not fuperfede the mea- fures propofed above for its cure : both becaufe we cannot certainly forefee what may be the confequences of fuch an acci- dent, and becaufe themeafures above fug- gefted are fafe; for, upon every fuppofition, it is a diathefis phlogiftica that may urge on every bad confequence to be appre- hended. DCCCLXVI. The fccond caufe of an ulceration of the lungs, to be confidered, is a fuppura- tioii formed in confequence of pneumo- nia. DCCCLXVII. Trom the fymptoms mentioned ill DCCCLVIII.-DCCLIX, it may with rea- fon OF PHYSIC. 375 fon be concluded, that an abfcefs, or, as it is called, a is formed in fome part of the pleura, and moft frequently in that portion of it inverting the lungs. Here purulent matter frequently remains for fome time, as if inclofed in a cyft : but commonly it is not long before it comes to be either abforbed, and transferred to fome other part of the body; or that it breaks through into the cavity of the lungs, or into that of the thorax. In the latter cafe, it produces the difeafe called empyema; but it is only when the matter is poured into the cavity of the bronchia?, that it properly conftitutes the phthifis pulmonalis. In the cafe of empyema, the chief circum- ftances of a phthifis are indeed alfo prefent; but I fhall here confider that cafe only in which the abfcefs of the lungs gives occa- lion to a purulent expe&oration. DCCCLXV1II. 376 PRACTICE DCCCLXVIIL An abfccfs of the lungs, in confequence of pneumonia, is not always followed by a phthifis : for fomctimes a hedtic fever is not formed ; the matter poured into the bronchia: is a proper and benign pus, which is frequently coughed up very rea- dily, and fpit out: and, though this puru- lent expectoration fhould continue for fome time, yet if a hedlic does not come on, the ulcer foon heals, and every morbid fymp- tom difappears. This has happened fo fre- quently, that we may conclude, that nei- ther the accefs of the air, nor the conftant motion of the lungs, will prevent an ulcer of thefe parts from healing, if the matter of it be well-conditioned. An abfcefs of the lungs, therefore, does not necefl'arily produce the phthifis pulmonalis ; and if it be followed by fuch a difeafe, it muft be in confequence of particular circumftances which OF PHYSIC. 377 which corrupt the purulent matter pro- duced, render it unfuitable to the healing of the ulcer, and at the fame time make it afford an acrimony, which, being abforbed, produces a heCtic and its confequences; DCCCLXIX. The corruption of the matter of fuch abfceffes may be owing to feveral caufes; as, i. That the matter effufed during the inflammation, had not been a pure ferum fit to be converted into a laudable pus, but had been united with other matters which prevented that, and gave a confiderable acrimony to the whole i Or, 2. That the matter effufed, and converted into pus, either merely by a long flagnation in a vo- mica, or by its connexion with an em- pyema, had been fo corrupted as to be- come unfit for the purpofe of pus, in the healing of the ulcer. Thefe feem to be Vol. II. B b poflible 378 PRACTICE poffiblc caufes of the corruption of matter in abfceffes, fo as to make it the occafion of a phthifis in perfons otherwife found ; but it is probable, that a pneumonic abfcefs docs cfpccially produce phthifis when it happens to perfons previoufly difpofed to that difeafe, and therefore only as it con- curs with foine other caufes of it. DCCCLXX. The third caufe fuppofed to produce phthifis, is a catarrh; which in many cafes feems, in length of time, to have the ex- pectoration of mucus proper to it, gra- dually changed into an expectoration of pus; and at the fame time, by the addi- tion of a hedtic fever, the difeafe, which was at firft a pure catarrh, is converted in- to a phthilis. This fuppofltion, however, is not eafily to be admitted. The catarrh is properly an affedlion, of the mucous glands OF PHYSIC. 379 glands of the trachea and bronchise, ana- logous to the coryza, and lefs violent kinds of cynanche tonlillaris, which very feldom terminate in fuppuration. And although a catarrh Ihould be difpofed to fuch termi- nation, yet the ulcer produced might rea- dily heal up, as it does in the cafe of a cy- nanche tonlillaris; and therefore Ihould not-produce a phthilis. DCCCLXXI. Further, the catarrh, as purely the effect of cold, is generally a mild difeafe, as well as of fliort duration; and of the numerous inftances of it, thereareatmoft butvery.few cafes which can be faid to have ended in phthilis. In all thofe cafes in which this feems to have happened, it is to me pro- bable, that the perfons affected were pecu- liarly predifpofed to phthilis. And the beginning of phthilis fo often refembles a Bb 2 catarrh, 380 PRACTICE catarrh, that the former may have been miftakcn for the latter. Befides, to increafe the fallacy, it often happens that the appli- cation of cold, which is the moft frequent caufe of catarrh, is alfo frequently the ex- citing caufe of the cough which proves the beginning of phthifis. DCCCLXXII. It is to me, therefore, probable, that a catarrh is very feldom the foundation of phthifis ; but I would not pofitively affert that it never is fo: for it is poffible that the cafes of a more violent catarrh may have joined with them a pneumonic affec- tion, which may. end in a fuppuration ; or it may happen that a long continued ca- tarrh, by the violent agitation of the lungs in coughing, will produce fome of thofe tubercles which are prefently to be men- tioned O F PHYSIC. 381 tioned as the molt frequent caufe of phthi- iis. DCCCLXXII1. It muft be particularly obferved here, that nothing faid in DCCCLXXIl. fhould allow us to negledt any appearance of ca- tarrh, as is too frequently done; for it may be either the beginning of a phthifis, which is miftaken for a genuine catarrh, or that even as a catarrh continuing long, it may produce a phthifis, as in DCCCLXXIl. DCCCLXXIV. Many phyficians have fuppofed an acri- mony of the fluids eroding fome of the veflels of the lungs, to be a frequent caufe of ulceration and phthifls. But this appears to me to be a mere fuppofition : for, in any ©f the inftances of the production of phthi- fia Bb 3 382 PRACTICE fis which I have feen, there was no evidence of any acrimony of the blood capable of eroding the veflels. It is true, indeed, that in many cafes an acrimony fubfifting in fome part of the fluids, is the caufe of the difeafe; but it is at the fame time pro- bable, that this acrimony operates by pro- ducing tubercles, rather than by any di- reft erofion. DCCCLXXV. It has been mentioned in DCCCLXIII. that an afthma may be confidered as one of the caufes of phthifis ; and by afthma I mean, that fpecies of it which has been commonlynamed theSpafmodic. Thisdif- eafe frequently fubfifts very long without producing any other, and may have its own peculiar fatal termination, as fhall be ex- plained hereafter. But 1 have feen it fre- quently end in phthifis ; and in fuch cafes I or PHYSIC. 383 I fuppofe it to operate in the manner above alledged of catarrh, that is, by producing- tubercles, and their confluences, which fhall be prefently mentioned. DCCCLXXVI. I come now to confider the fifth head of the caufes of phthifis, and which I ap- prehend to be the moft frequent of any. This I havefaid, in general, to be tubercles; by which term are meant, certain fmall tumours, which have the appearance of in- durated glands. Diffcdions have fre- quently ihown fuch tubercles formed in the lungs ; and although at iirft indolent, yet at length they become inflamed, and are thereby changed into little abfcefTes, or vomicae, which breaking, and pouring their matter into the branching, give a pu- rulent expedoration, and thus lay the foundation of phthifis. B b 4 DCCCLXXVII. 384 PRACTICE DCCCLXXVIL Though the matter expectorated upon thefe occafions has the appearance of pus, it is feldom that of a laudable kind ; and, as the ulcers do not readily heal, but are attended with a hedtic fever, for the moft part ending fatally, I prefume that the mat- ter of the ulcers is imbued with a pecu- liarly noxious acrimony, which prevents their healing, and produces a phthifis in all its circumftances, as mentioned above. PCCCLXXVIIL It is very probable that the acrimony which thus difcovers itfelf in the ulcers, cxifted before and produced the tubercles fhemfelves ; and it is to this acrimony that we mutt trace up the caufe of the phthifis following thefe tubercles. This acrimony is < * OF PHYSIC. 385 is probably, in different cafes, of different kinds; and it will not be eafy to determine its varieties : but to a certain length 1 lhall attempt it. DCCCLXXIX. In one cafe, and that, too, a very fre- quent one, of phthifis, it appears, that the noxious acrimony is of the fame kind with that which prevails in the fcrophula. This may be concluded from obferving, that a phthifis, at its ufual periods, frequently at- tacks perfons born of fcrophulous parents; that is, of parents who had been affected with fcrophula in their younger years : that very often, when the phthifis appears, there occur at the fame time fome lym- phatic tumours in the external parts ; and very often I have found the tabes mefen- terica, which is a fcrophulous affeftion, joined with the phthifis pulmonalis. To all 386 PRACTICE all this I would add, that, even when no fcrophulous affection has either manifeftly preceded or accompanied a phthilis, this laft however molt commonly affedts per- fons of a habit refembling the fcrophulous; that is, perfons of a fanguine, or of a fanguineo-melancholic temperament, who have very fine Ikins, rofy complexions, large veins, foft flefh, and thick upper-lip : and further, that in fuch perfons the phthi- fis comes on in the fame manner that it does in perfons having tubercles, as (hall be immediately explained. DCCCLXXX. Another fpecies of acrimony producing tubercles of the lungs, and thereby phthi- fis, may be faid to be the exanthematic. It is well known, that the fmall-pox fome- times, and more frequently the mealies, lay the foundation of phthilis. It is probable alfo, OF PHYSIC. 387 alfo, that other exanthemata have the fame effect j and from the phenomena of the dif- eafe, and the diffe&ions of perfons who have died of it, it is probable, that all the exan- themata may occafion a phthifis, by afford- ing a matter which in the firft place pro- duces tubercles. DCCCLXXXL Another acrimony, which Teems Tome- times to produce phthifis, is the fiphylitic: but whether Tuch an acrimony produces phthifis in any other perfons than the pre- vioufly difpofed, does not appear to me cer- tain. DCCCLXXXIL What other fpecies of acrimony, fiich as from fcurvy, from pus abforbed from other parts of the body, from fupprefled erup- tionsf 388 PRACTICE tions, or from other fources, may alfo pro- duce tubercles and phthifis, I caYmot now decide, but muft leave to be determined by thofe who have had experience of fuch cafes. DCCCLXXXIII. There is one peculiar cafe of phthifis, which from my own experience I can take notice of. This is the cafe of phthifis from a calcareous matter formed in the lungs, and coughed up, frequently with a little blood, fometimes with mucus only, and fometimes with pus. How this matter is generated, or in what precife part of the lungs it is feated, I acknowledge myfelf ignorant. In three cafes of this kind which have occurred to me, there was at the fame time no appearance of ftony or ear- thy concretions in any other part of the body. In one of thefe cafes, an exquiiitely formed OF PHYSIC. 389 formed phthifis came on, and proved mor- tal : while in the other two, the fymptoms of phthifis were never fully formed ; and after fome time, merely by a milk diet and avoiding irritation, the patients entirely re- covered. DCCCLXXXIV. Another foundation for phthifis, analo- gous, as I judge, to that of tubercles, is that which occurs to certain artificers whofe employments keep them almoft conftantly expofed to duft; fuch as ftone-cutters, mil- lers, flax-drefiers, and fome others. I have not obferved in this country many inftances of phthifis which could be referred to this caufe; but, from Ramazzini, Mor- gagni, and fome other writers, we muft conclude fuch cafes to be more frequent in the fouthern parts of Europe. DCCCLXXXV. 390 PRACTICE DCCCLXXXV. Befides thofe now mentioned, there are probably fome other caufes producing tu- bercles, which have not yet been afcertained by obfervation; and it is likely, that in the Hate of tubercles there is a variety not yet accounted for: but all this muft be left to future obfervation and inquiry. DGCCLXXXVI. It has been frequently fuppofed by phy- sicians, that the phthilis is a contagious dif- eafe ; and I dare not affert that it never is fuch : but in many hundred inftances of the difeafe which I have feen, there has been hardly one which to me could appear to have arifen from contagion. It is pof- fible, that in warmer climates the effects of contagion may be more difcernible. After having faid that a phthifis arifes from Of PHYSIC. 391 from tubercles more frequently than from any other caufe, and after having attempted to aflign the variety of thefe, I now pro- ceed to mention the peculiar circumftances and fymptoms which ufually accompany the coming on of the difeafe from tu- bercles. DCCCLXXXVII. A tuberculous and purulent date of the lungs has been obferved in very young children, and in fome others at feveral dif- ferent periods before the age of puberty and full growth; but inftances of this kind are rare : and the attack of phthifis, which we have reafon to impute to tubercles, ufually happens at the fame period which I have afligned for the coming on of the hemoptyiis. DCCCLXXXV1II. 392 PRACTICE DCCCLXXXVIII. The phthifls from tubercles does alfo ge- nerally aflccl the fame habits as the hemop- tyfls, that is, perfons of a flender make, of long necks, narrow cherts, and prominent fhoulders : but very frequently the per- fons liable to tubercles have lefs of the flo- rid countenance, and of the other marks of an exquifitely fanguine temperament, than the perfons liable to hemoptyfls. DCCCLXXXIX. This difeafe, arifing from tubercles, ufu- ally commences with a flight and fhort cough, which becomes habitual, is often little remarked by thofe a fleet cd, and fome- times fo little as to be abfolutely denied by them. At the fame time their breathing becomes eafily hurried by any bodily mo- tion, their body grows leaner, and they be- come OF PHYSIC. 393 come languid and indolent. This flate fometimes continues for a year, or even for two years, without the perfons making any complaint of it, excepting only that they are affected by cold more readily than ufual, which frequently increafes their cough, and produces fome catarrh. This, again, however, is fometimes relieved; is fuppofed to have arifen from cold alone; and therefore gives no alarm either to the patient or to his friends, nor leads them to take any precautions. DCCCXC. Upon one or other of thefe occasions of catching cold, as we commonly fpeak, the cough becomes more conliderable; is par- ticularly troublefome upon the patient's ly- ing down at night, and in this ftate con- tinues longer than is ufual in the cafe of a limple catarrh. This is more efpecially to Vol.IL Cc call 394 PRACTICE call for attention, if the increafe and con- tinuance of cough come on duringthe fum- mer feafon. DCCCXCI. The cough which comes on as in DCCCLXXX1X. is very often for a long time without any expectoration; but when, from repeatedly catching cold, it becomes more conftant, it is then at the fame time attended with fome expectoration, which is molt confiderable in the mornings. The matter of this expectoration becomes by degrees more copious, more vifcid, and more opake; at length of a yellow or greenifh colour, and of a purulent appear- ance. The whole of the matter, however, is not always at once entirely changed in this manner ; but, while one part of it re- tains the ufual form of niucus, another fuf- fers the changes now defcribed. DCCCXCIb OF PHYSIC. 395 DCCCXCII. When the cough increafes, and conti- nues very frequent through the night, and when the matter expectorated undergoes the changes I have mentioned, the breathing at the lime time becomes more difficult, and the emaciation and weaknefs go on al- fo increaling. In the female fex, as the dif- eafe advances, and fometimes early in its progrefs, the menfes ceafe to flow ; and this cirCumftance is to be confidered as commonly the efleCt, although the fex themfelves are ready to believe it the foie caufe, of the difeafe. DCCCXCIII. When the cough comes on as in DCCCLXXXIX. the pulfe is often natu- ral, and for fome time after continues to be fo; but the fymptoms have feldom fub- fifted C C 2 396 PRACTICE iifted long before the pulfe becomes fre- quent, and fometimes to a conliderable de- gree, without much of the other fymptoms of fever. At length, however, evening ex- acerbations become remarkable; and by de- grees the fever ailumes the exquifite form of hedic, as defcribed in DCCCLVI1I.- DGCCLX. ' DCCCXC1V. It is feldom that the cough, expectoration, and fever, go on increafing, in the manner now defcribed, without fome pain being felt in fome part of the thorax. It is ufu- ally and moft frequently felt at firft under the fternum, and that efpecially, or almoft only, upon occafion of coughing : but very often, and that too early, in the courfe of the difeafe, a pain is felt on one fide, fome- times very conftantly, and fo as to prevent the perfon from lying eafily upon that fide; but OF PHYSIC. 397 but at other times the pain is felt only upon a full infpiration, or upon coughing. Even when no pain is felt, it generally happens that phthifical perfons cannot lie eafily on fome one of their iides without having their difficulty of breathing increafed, and their cough excited. DCCCXCV. The phthilis begins, and fometimes pro- ceeds to its fatal iffiue,in the manner defcri- bed from DCCCLXXXIX. to DCCCXCV. without any appearance of hemoptylis. Such cafes are, indeed, rare; but it is very common for the difeafe to advance far, and even to an evident purulency and hecftic Hate, without any appearance of blood in the fpitting : fo that it may be affirmed, the difeafe is frequently not founded in he- moptyfis. At the fame time, we mull al- low, not only that it fometimes begins with Ccs an 398 PRACTICE an hemoptyfis, as is faid in DCCCLXIV.; but further, that it feldom happens that in the progrcfs of the difeafe more or lefs of an hemoptyfis does not appear. Some degree of blood-fpitting does, indeed, appear fometimes in the date mentioned DCCCLXXX1X. DCCCXCI1I. but more commonly in the more advanced flages of the difeafe only, and particularly upon the firft appearance of purulency. How- ever this may be, it is feldom, in the phthi- fis from tubercles, that the hemoptyfis is confiderable, or requires any remedies dif- ferent from thofe which are otherwife ne- ceffary for the ftate of the tubercles. DCCCXCVL I have now defcribed a fucccflion of fymptoms which, in different cafes, occupy more or lefs time. In this climate they very often take up fome years, the fymp- toms 0 F ,P H Y S I C. 399 toms appearing efpecially in the winter and fpring; commonly becoming eafier, and fometimes almoftdifappearing, during the fummer : but returning again in win- ter, they at length, after two or three years, prove fatal, towards the end of fpring or beginning of fummer. DCCCXCVII. In this difeafe, the prognofis is for the moil part unfavourable. Of thofe affected with it, the greater number die; but there are alfo many of them who recover entirely, after having been in very unpromiling cir- cumftances. What are, however, the cir- cumftances more certainly determining to a happy or to a fatal event, I have not yet been able to afcertain. C c 4 DCCCXCVIIL 400 PRACTICE DCCCXCVIIT. The following aphorifnas are the refill t of mv observations. J A phthifis pulmonalis from hemoptyfis, is more frequently recovered than one from tubercles. An hemoptyfis not only is not always followed by a phthifis, as we have faid above (DCCCLXIV.) ; but even when followed by an ulceration, the ulceration is fometimes attended with little of hedlic, and frequently admits of being foon heal- ed. Even when the hemoptyfis and ulcer- ation have happened to be repeated, there are inftances of perfons recovering entirely after feveral fuch repetitions. A phthifis from a Suppuration in confe- quence of pneumonic inflammation, is that which moil rarely occurs in this climate ; and a phthifis does not always follow fuch Suppuration, when the abfcefs formed fcon OF PHYSIC. 401 foon breaks and difcharges a laudable pus: but, if the abfcefs continue long fhut up, and till after a confidcrable degree of bee- tic has been formed, a phthifis is then pro- duced, equally dangerous, as that front other caufes. A phthifis from tubercles has, I think, been recovered : but it is of all others the moft dangerous ; and, when arifing from a hereditary taint, is almoft certainly fa- tal. The danger of a phthifis, from whatever caufe it may have arifen, is moft certainly to be judged of by the degree to which the hedic and its confcquences have arrived. From a certain degree of emaciation, debi- lity, profufe fweating, and diarrhoea, no perfon recovers. A mania coming on, has been found to remove all the fymptoms, and fometimes has entirely cured the difeafe; but, in other cafes. 402 PRACTICE cafes, upon the going off of the mania, the phthifis has recurred, and proved fatal. The pregnancy of women has often re- tarded the progrefs of a phthifis; but com- monly it is only till after delivery, when the fymptoms of phthifis return with vio- lence, and foon prove fatal. SECT, OF PHYSIC. 403 SECT. IL Of the Cure of Phthisis. DCCCXCIX. From what has been juft now faid, it will readily appear, that the cure of the phthifis pulmonalis muft be exceedingly difficult; and that even the utmoft care and attention in the employment of reme- dies, have feldom fucceeded. It may be doubtful whether this failure is to be im- puted to the imperfection of our art, or to the abfolutely incurable nature of the dif-* eafe. 404 PRACTICE eafe. I am extremely averfe in any caffe to admit of the latter fuppofition, and can always readily allow of the former; but, in the mean time, muft mention here, what has been attempted towards either curing or moderating the violence of this dif- eafe. DCCCC. It muft be obvious, that according to the different circumftances of this difeafe, the method of cure muft be different. Our firft attention fhould be employed in watch- ing the approach of the difeafe, and pre- venting its proceeding to an incurable ftate. In all perfons of a phthifical habit, and efpecially in thofe born of phthifical pa- rents, the flighted: fymptoms of the ap- proach of phthifis, at the phthifical period of life, ought to be attended to. DCCCCI. OF PHYSIC. 405 DCCCCI. When an hemopty fis occurs, though it be not always followed with ulceration and phthifis, thefe however are always to be apprehended ; and every precaution is to be taken againft them. This is efpe- cially to be done by employing every means of moderating the hemorrhagy, and of preventing its return, directed in DCCCXCI1. et feq.; and thefe precautions ought to be continued for feveral years af- ter the occurrence of the hemoptyfis. DCGCCII. The phthifis which follows a fuppuration from pneumonic inflammation, can only be prevented with certainty, by obtaining a refolution of fuch inflammation. What may be attempted towards the cure of an abfcefs 406 PRACTICE abfeefs and ulcer which have taken place, I fhall fpeak of hereafter. DCCCCI1I. I have faid, it is doubtful if a genuine catarrh ever produces a phthiiis; but have allowed that it poffibly may : and both upon this account, and upon account of the ambiguity which may arife, "whether the appearing catarrh be a primary dif- eafe, or the effect of a tubercle, I confider it as of confequence to cure a catarrh as foon as poffible after its firft appearance. More efpecially when it (hall linger, and continue for fome time, or Ihall, after fome intermiffion, frequently return, the cure of it fhould be diligently attempted. The meafures requifite for this purpofe Ihall be mentioned afterwards, when we come to treat of catarrh as a primary difeafe; but, in the mean time, the means necef- fary OF PHYSIC. 407 fary for preventing its producing a phthi- fis (hall be mentioned immediately, as they are the fame with thofe 1 fhall point out as neceflary for preventing a phthifis from tubercles. DCCCCIV. The preventing of a phthifis from afthma muft be, by curing, if poflible, the afthma, or at leaft by moderating it as much as may be done : and as it is probable that afthma occalions phthifis, by producing tubercles, the meafures neceflary for pre- venting phthifis from afthma, will be the fame with thofe necefiary in the cafe of tubercles, which 1 am now about to men- tion. DCCCCV. I confider tubercles as by much the moft fre- 408 PRACTICE frequent caufe of phthifis ; and even in many cafes where this feeins to depend upon hemoptyfis, catarrh, or afthma, it does however truly arife from tubercles. It is upon this fubjed, therefore, that I dliall have occafion to treat of the mea- fures moil commonly requifite for curing phthifis. DCCCCVI. When, in a perfon born of phthifical parents, of a phthifical habit, at the phthifical period of life, the fymptoms (DCCCLXXX1X.) in the fpring, or begin- ning of fummer, fliall appear in the Highteft degree, we may prefume that a tubercle, or tubercles, either have been formed, or are forming in the lungs ; and therefore, that every means we can devife for pre- venting their formation, or for procuring their refolution, fiiould be employed im- mediately, O F. P H Y S I C. 409 mediately, even although the patient him- lelf ihould overlook or neglect the fymp- toms, as imputing them to accidental cold. DCCCCVIL This is certainly the general indication; but how it may be executed, I cannot rea- dily fay. I do not know that, at any time, phyficians have propofed any remedy ca- pable of preventing the formation of tu- bercles, or of refolving them when formed. The analogy of fcrophula, gives no allift- ance in this matter. In fcrophula the reme- dies that are feemingly of mod power are, fea-water, or certain mineral waters ; but thefe have generally proved hurtful in the cafe of tubercles of the lungs. I have known feveral inftances of mercury very fully employed for certain difeafes, in per- fons who were fuppofed at the time to VOL. II. Dd have. 410 PRACTICE have tubercles formed, or forming, in their lungs ; but though the mercury proved a cure for thofe other difeafes, it was of no fcrvicc in preventing phthifis, and in fome cafes feemed to hurry it on. DCCCCVI1L Such appears to me to be the prefent Rate of our art, with refpedt to the cure of tubercles; but I do notdefpair of a remedy for the purpofe being found hereafter. In the mean time, all that at prefent feems to be within the reach of our art, is to take the meafures proper for avoiding the in- flammation of tubercles. It is probable that tubercles may fubfift long without producing any diforder: and 1 am difpofed to think, that nature fometimes refolves and difeufles tubercles which have been formed; but that nature does this only when the tubercles remain in an unin- flamed OF PHYSIC. 411 flamed flate ; and therefore, that the mea- fures neceflary to be taken, are chiefly thofe for avoiding the inflammation of the tubercles. DCCCCIX. The inflammation of a tubercle of the lungs is to be avoided upon the general plan of avoiding inflammation, by blood- letting, and by an antiphlogiftic regimen; the chief part of which, in this cafe, is the ufe of a low diet. This fuppofes a total abftinence from animal-food, and the ufing of vegetable food almoft alone : but it has been found, that it is not neceflary for the patient to be confined to vegetables of the weakeft nourilhment, it being fufficient that the farinacea be employed, and toge- ther with thefe, milk. D d 2 DCCCCX, 412 PRACTICE DCCCCX. Milk has been generally confidered as the chief remedy in phthifis, and in the cafe of every tendency to it; but whe- ther from its peculiar qualities, or from its being of a lower quality, with refpedt to nourifhmcnt, than any food entirely ani- mal, is not certainly determined. The choice and adminiftration of milk will be properly diredied, by confidering the na- ture of the milk of the feveral animals from which it maybe taken, and the par- ticular ftate of the patient with refpect to the period and circumftances of the dif- eafe, and to the habits of his ftomach with refpecl to milk. DCCCCXI. A fecond means of preventing the in- flammation of the tubercles of the lungs, is. OF PHYSIC. 413 is, by avoiding any particular irritation of the affeded part, which may arife from any violent exercife of refpiration; from any confiderable degree of bodily exercife; from any petition of the body which ftraitens the capacity of the thorax ; and, laftly, from cold applied to the furface of the body, which determines the blood in greater quantity to the internal parts, and particularly to the lungs. DCCCCXII. From the laft-mentioned confidefation, the application of cold in general, and therefore the winter-feafon, in cold cli- mates, as diminifliing the cutaneous per- fpiration, is to be avoided ; but more par- ticularly, that application of cold is to be fhunned that may fupprefs perfpiration, to the degree of occafioning a catarrh, which confifts in an inflammatory determination D d 3 to 414 PRACTICE to the lungs, and may therefore moft cer- tainly produce an inflammation of the tu- bercles there. By confldering, that the avoiding heat is a part of the antiphlogiftic regimen above recommended, and by comparing this with what has been juft now faid refpecfting the avoiding cold, the proper choice of cli- mates and feafons for phthiflcal patients will be readily underftood. DCCCCXI1I. A third means of avoiding the inflam- mation of the tubercles of the lungs con- lifts, in diminifhing the determination of the blood to the lungs, by fupporting and increaflng the determination to the furface of the body ; which is to be chiefly and moft fafely done by warm cloathing, and thefrequent ufeof theexercifesofgeftation. DCCCCXIV. OF PHYSIC. 416 DCCCCXIV. Every mode of geftation has been found of ufe in phthifical cafes ; but riding on horfeback, as being accompanied with a great deal of bodily exercife, is lefs fafe in perfons liable to an hemoptyfis. Travel- ling in a carriage, unlefs upon very fmooth roads, may al Co be of doubtful effedl; and all the modes of geftation that are em- ployed on land, may fall Ihort of the ef- fects expected from them, becaufe they cannot be rendered lufficienrly conftant; and therefore it is that failing, of all other modes of geftation, is the moft effectual in pneumonic cafes, as being both the fmooth - eft and moft conftann It has been imagined, that fome benefit is derived from the ftate of the atmofphere upon the fea: but I cannot find that any impregnation of this which can be fuppo- fed to take place, can be of fervice to phthi- fical D d 4 416 PRACTICE fical perfons. It is however probable, that frequently fome benefit may be derived from the more moderate temperature and greater purity of the air upon the fea. DCCCCXV. In order to take off any inflammatory determination of the blood into the veffels of the lungs, blifters applied to fome part of the thorax may often be of fervice ; and for the fame purpofe, as well as for mode- rating the general inflammatory (late of the body, iffues of various kinds may be employed with advantage. DCCCCXVI. • The feveral meafures to be purfued in the cafe of what is properly called an Inci- pient Phthifis, have now been mentioned ; but they have feldom been employed in fuch Of PHYSIC. 417 fuch cafes in due time, and have therefore, perhaps, feldom proved effectual. It has more commonly happened, that after fome time, an inflammation has come upon the tubercle, and an abfcefs has been form- ed, which opening into the cavity of the bronchiae, has produced an ulcer, and a confirmed phthifis. dccccxvii. In this Rate of matters, fome new indi- cations different from the former may be fuppoled to arife; and indications for pre- venting abforption, for preventing the ef- fects of the abforbed matter upon the blood, and for healing the ulcer, have been actually propofed. I cannot find, however, that any of the means propofed for executing thefe indications, are either probable or have proved effectual. If, upon fome occafions, they have appeared to be ufeful, 418 PRACTICE ufeful, it has been probably by anfwering fome other intention. While no antidote againft the poifon which efpecially operates here, feems to have been as yet found out, it appears to me, that too great a degree of inflammation has agrcatfhare in preventing the healing of the ulcer which occurs; and fuch inflamma- tion is certainly what has a great ihare in urging on its fatal confequences. The only practice, therefore, which I can venture to propofe, is the fame in the ulcerated as in the crude ftate of a tubercle; that is, the employment of means for moderating in- flammation, which have been already men- tioned (DCCCCIX. etfeq.}. DCCCCXV1IL The balfamics, whether natural or arti- ficial, which have been fo commonly ad- vifed in cafes of phthifis, appear to me to have OF PHYSIC. 419 have been propofed upon no fuffleient grounds, and to have proved commonly hurtful. The reiinous and acrid fubflance of myrrh, lately recommended, has not ap- peared to me to be of any fervice, and in fome cafes to have proved hurtful. DCCCCX1X. Mercury, fo often ufeful in healing ul- cers, has been fpecioufly enough propofed in this difeafe ; but whether that it be not adapted to the particular nature of the ul- cers of the lungs occurring in phthifis, or that it proved hurtful becaufe it cannot have effect, without exciting fuch an in- flammatory flate of the whole fyftem, as, in a hedlic ftate, muft prove very hurtful, I cannot determine. Upon many trials which I have feen made, it has proved of no fervice, and commonly has appeared to be manifeftly pernicious. DCCCCXX, 420 PRACTICE DCCCCXX. The Peruvian bark has been recommend- ed for feveral purpofcs in phthifical cafes ; and is faid, upon fome occafions to have been ufeful; but I have feldom found it to be fo: and as by its tonic power it in- creafes the phlogiflic diathefis of the fyf- tem, I have frequently found it hurtful. In fome cafes, where the morning remif- fions of the fever were confiderable, and the noon exacerbations well marked, I have obferved the Peruvian bark given in large quantities, with the effedl of flopping thefe exacerbations, and at the fame time of re- lieving the whole of the phthifical fymp- toms : but in the cafes in which I obferved this, the fever {bowed a conflant tendency to recur; and at length the phthifical fymp- toms alfo returned, and proved quickly fa- tal. DCCCCXXL OF PHYSIC. 421 DCCCCXXL Acids of all kinds, as antifeptic and re- frigerant, are ufeful in cafes of phthifis ; but the native acid of vegetables is more ufeful than the foffil acids, as it can be gi- ven in much larger quantities, and may alfo be given more fafely than vinegar, be- ing lefs liable to excite coughing. DCCCCXXII. Though our art can do fo little towards the cure of this difeafe, we muft, however, palliate the uneafy fymptoms of it as well as we can. The fymptoms efpecially ur- gent, are the cough and diarrhoea. The cough may be in fome meafure relieved by demulcents, (DCCCLXXIIL); but therelief obtained by thefe is imperfcdt and tranfj- tory, and very often the ilomachis difturb- ed by the quantity of oily, mucilaginous, and 422 practice and fweet fubllances, which are on thefe occafions taken into it. pccccxxin. The only certain means of relieving the cough, is by employing opiates. Thefe, indeed, certainly increafe the phlogiftic diathefis of the fyftem; but commonly they do not fo much harm in this way, as they do fervice by quieting the cough, and giving fleep. They are fuppofed to be hurtful by checking expectoration: but they do it for a fliort time only ; and, af- ter a found deep, the expectoration in the morning is more eafy than ufual. In the advanced (late of the difeafe, opiates feem to increafe the fweatings that occur ; but they compenfate this, by the eafe they af- ford in a difeafe which cannot be cured. dccccxxiv. OF PHYSIC. 423 DCCCCXX1V. The diarrhoea which happens in the ad- vanced Hate of this difeafe, is to be pal- liated by moderate aftringents, mucilages, apd opiates. Rhubarb, fo commonly prefcribed in every diarrhoea, and all other purgatives, are extremely pernicious in the colliquative diarrhoea of hedlics. * Frefh fubacid fruits, fuppofed to be al- ways laxative, are often, in the diarrhoea of hectics, by their antifeptic quality, very ufeful.

But a difcharge of blood from within the anus, when the blood is of a florid colour, fliowing it to have come from no great diftance, is alfo confidered as the fame difeafe ; and phyfi- cians have agreed in making two cafes or varieties of it, under the names of Exter- nal and Internal Hemorrhois. DCCCCXXVI. In both cafes it is fuppofed that the flow of blood is from tumours previoufly formed, which are named Hemorrhoids, or Piles; and it frequently happens, that the tu- mours exift without any difcharge of blood • in which cafe, however, they are fuppofed to be a part of the fame difeafe, and are named Hemorrhoides Cascaz, or Blind Piles. Vol. II. Ee DCCCCXXVII* 426 PRACTICE DCCCCXXVII. Thefe tumours, as they appear without the anus, are fometimes feparate, round, and prominent, on the verge of the anus ; but frequently the tumour is only one tu- mid ring, forming, as it were, the anus puffied without the body. DCCCCXXVIII. Thefe tumours, and the difcharge of blood from them, fometimes come on as an affection purely topical, and without any previous difordcr in other parts of the body : but it frequently happens, even before the tumours are formed, and more efpecially before the blood flows, that va- rious diforders are felt in different parts of the body, as headach, vertigo, ftupor, difficulty of breathing, ficknefs, colic- pains, pain of the back and loins and often. OF PHYSIC. 427 often, together with more or fewer of thefe fymptoms, there occurs a confider- able degree of pyrexia. The coming on of the difeafe with thefe fymptoms, is ufually attended withafenfe of fullnefs, heat, itching, and pain in and about the anus. Sometimes the difeafe is preceded by a difeharge of ferous matter from the anus: and fometimes this ferous difeharge, ac- companied with fome fwelling, feems to be in place of the difeharge of blood, and to relieve thofe diforders of the fyftem which we have mentioned. This ferous difeharge, therefore, has been named the Hemorrhois Alba. DCCCCXXIX. In the hemorrhois, the quantity of blood difcharged is different upon different occa- fions. Sometimes the blood flows only E e 2 upon 428 PRACTICE upon the perfon's going to ftool; and com- monly, in larger or lefler quantity, follows the difcharge of the faeces, in other cafes, the blood flows without any difcharge of faeces ; and then, generally, it is after ha- ving been preceded by the diforders above- mentioned, when it is alfo commonly in larger quantity. This difcharge of blood is often very conflderable ; and, by the re- petition, it is often fo great, as we could hardly fuppofe the body to bear but with the hazard of life. Indeed, though rarely, it has been fo great as to prove fuddenly fatal. Thefe conflderable difcharges occur efpecially to perfons who have been fre- quently liable to the difeafe. They often induce great debility; and frequently a leucophlegmatia, or dropfy, which proves fatal. The tumours and difcharges of blood in this difeafe, often recur at exadlly Rated periods. DCCCCXXX. OF PHYSIC. 429 DCCCCXXX. It often happens, in the decline of life, that the hemorrhoidal flux, formerly fre- quent, ceafes to flow; and, upon that event, it generally happens that the per- fons are afledted with apoplexy or palfy. DCCCCXXXI. Sometimes hemorrhoidal tumours are affedled with coniiderable inflammation; which, ending in fuppuration, gives occa- fion to the formation of fiftulous ulcers in thofe parts. DCCCCXXXII. The hemorrhoidal tumours have been often confidered as varicous tumours, or xlilatations of veins ; and it is true, that in fome cafes varicous dilatations have appear- ed E e 3 PRACTICE 430 ed upon difledion. Thefe, however, do not always appear ; and 1 prefume it is not the ordinary cafe, but that the tumours are formed by an effufion of blood into the cellular texture of the inteftine near to its extremity. Thefe tumours, when recently formed, frequently contain fluid blood ; but, after they have remained for fome time, they arc commonly of a firmer fub fiance. DCCCCXXXIil. From a confideration of their caufes, to be hereafter mentioned, it is fufficiently probable, that hemorrhoidal tumours are produced by fpinc interruption of the free return of blood from the veins of the lower extremity of the redum; and it is pofiiblc, that a confidcrable accumulation of blood in thefe veins, may occasion a rupture of their extremities, and thus pro- duce Of PHYSIC. 431 duce the hemorrhagy or tumours I have mentioned. But, confidering that the he- morrhagy occurring here, is often preceded by pain, inflammation, and a febrile ftate, as well as by many other fymptoms which ihow a connection between the topical affec- tion and the ftate of the whole fyftem, it feems probable that the interruption of the venous blood, which we have fuppofed to take place, operates in the manner ex- plained inDCCLXIX.; and therefore, that the difcharge of blood here is commonly from arteries. DCCCCXXXIV. Some phyficians have been of opinion, that a difference in the nature oi the he- morrhois, and of its effects upon the fy- ftem, might arife from the difference of the hemorrhoidal veffels from which the blood iffued. But it appears to me, that Ee 4 hardly 432 PRACTICE hardly in any cafe we can diftinguifli the velfcls from which the blood flows; and that the frequent inofculations, of both the arteries and veins which belong to the lower extremity of the return, will render the effects of the hemorrhagy near- ly the fame, from whichfoever of thefe veflels the blood proceed. DCCCCXXXV. In DCCLX1X. I have endeavoured to explain the manner in which a certain Rate of the fanguiferous fyftem might give occafion to an hemorrhoidal flux; and I have no doubt, that this flux may be pro- duced in that manner. I cannot, however, by any means admit that the difeafe is fo often produced in that manner, or that, on its firfl appearance, it is lb frequently a fyftematic afiecflion, as the Stahlians have imagined, and would have us to believe. Ic occurs OF PHYSIC. 433 occurs in many perfons before the period of life at which the venous plethora takes place ; it happens to females, in whom a venous plethora, determined to the hemor- rhoidal vefTels, cannot be fuppofed; and it happens to both fexes, and to perfons of all ages, from caufes which do not affect the fyftem, and are inanifeftly fuited to produce a topical affection only. DCCCCXXXVL Thefe caufes of a topical affe&ion are, in the fir it place, the frequent voiding of hard and bulky faeces, which, not only by their long flagnation in the rectum, but Spe- cially when voided, mutt prefs upon the veins of the anus, and interrupt the courfe of the blood in them. It is for this rea- fon that the difeafe happens fo often to perlons of a flow and bound belly. DCCCCXXXVIL 434 PRACTICE DCCCCXXXVII, From the caufes juft now mentioned, the difeafe happens efpecially to perfons liable to fome degree of a prolapfus ani. Almoft every perfon in voiding feces has the internal coat of the return more or Icfs protruded without the body; and this will be to a greater or leffer degree, accor- ding as the hardncfs and bulk of the feces occafion a greater or leffer effort or pref- fure upon the anus. While the gut is thus pu filed out, it often happens, that the fphinder ani is contracted before the gut is replaced; and, in confequence thereof, a ftrong conftriction is made, which pre- venting the fallen-out gut from being re- placed, and at the fame time preventing the return of blood from it, occafions its being confiderably fwellcd, and its form- ing a tumid ring round the anus. DCCCCXXXV1IL o F P H Y S I C. 435 DCCCCXXXVIII. Upon the fphinfler's being a little re- laxed, as it is immediately after its ftrong contraction, the fallen-out portion of the gut is commonly again taken within the body; but, by the frequent repetition of Rich an accident, the fize and fullnefs of the ring formed by the fallen-out gut, is much increafed. It is therefore more flow- ly and difficultly replaced; and in this conffils the chief uneafmefs of hemorrhoi- dal perfons. DCCCCXXXIX. As the internal edge of the ring men- tioned, is neceflarily divided by clefts, the whole often affumes the appearance of a number of diflind fwellings ; and it alfo frequently happens, that feme portions of it 436 PRACTICE it more confiderably fwelled than others, become more protuberant, and form thofe fmall tumours more ftriCtly called Hemor- rhoids, or Piles. DCCCCXL. From confidering that the prefiure of feces, and other caufes interrupting the return of venous blood from the lower ex- tremity of the reftum, may operate a good deal higher up in the gut than that extre- mity, it may be eafily underftood that tu- mours may be formed within the anus; and probably it alfo happens, that fome of the tumours formed without the anus, as in DCCCCXXXIX. may continue when taken within the body, even be increafed by the caufes juft now mentioned. It is thus that I 'would explain the production of in- ternal piles, which, on account of their fituation and bulk, are not protruded on the OF PHYSIC. 437 the perfon's going to ftool, and are often, therefore, more painful. The fame inter- nal piles are more efpecially painful, when affedled by the hemorrhagic effort defcri- bed in DCCXLV. and DCCLXIX. DCCCCXLI. The production of piles is particularly illultrated by this, that pregnant women are frequently affeCted with them. This is to be accounted for, partly from the preffure of the uterus upon the rectum, and partly from the coftive habit to which pregnant women are ufually liable. I have known many inftances of piles occurring for the fir ft time during the ftate of preg- nancy ; and there are few women that have born children who are afterwards entirely free from piles. The Stahlians have commonly afierted, that the male fex is more frequently affeCted with this dif- eafe 438 PRACTICE. eafe than the female; but in this country I have conflantly found it otherwife. DCCCXLII. It is commonly fuppofed, that the fre- quent ufe of purgatives, efpccially of thofe of the more acrid kind, and more particu- larly of aloetics, is apt to produce the he- morrhoidal affection ; and as thefe purga- tives ftimulate chiefly the great guts, it feems fufficiently probable that they may excite this difeafe. DCCCCXLlli. I have now mentioned feveral can Fes which may produce the hemorrhoidal tu- mours and flux as a topical affecflion only; but muft obferve farther, that although the difeafe appears firfl: as a purely topical affedtion, it may, by frequent repetition, become habitual, and therefore may be- come OF PHYSIC. 439 come connected with the whole fyflem, in the manner already explained, with refpecl to hemorrhagy in general, in DCCXLVI1I. DCCCCXLIV. The dodlrine now referred to, will, it is apprehended, apply very fully to the cafe of the hemorrhoidal flux; and will the more readily apply, from the perfon who has been once affected being much expofed to a re- newal of the caufes which firfl occalioned the difeafe; and from many perfons being much expofed to a congeflion in the he- morrhoidal veflels, in confequenCe of their being often in an eredl pofition of the body, and in an exercife which pufhes the blood into the depending veflels, while at the fame time the effects of thefe circum- ilances are much favoured by the abun- dance and laxity of the cellular texture about the redlum. DCCCCXLV. 440 PRACTICE DCCCCXLV. It is thus that the hemorrhoidal flux is fo often artificially rendered an habitual and fyflematic affeCtion ; and 1 am perfua- ded, that it is this which has given occa- iion to the Stahlians to confider the difeafe as almofl univerfally fuch. DCCCCXLVI. It is to be particularly obferved here, that when the hemorrhoidal difeafe has either been originally, or has become, in the manner juft now explained, a fyftema- tic affection, it then acquires a particular connexion with the ftomach, fo that cer- tain affections there excite the hemorrhoi- dal difeafe, and certain ftates of the hemor- rhoidal affeClion excite diforders of the fto- mach. It is perhaps owing to this connection, that the gout fometimes affects the re&um. See DXXV. SECT. OF PHYSIC. 441 SECT. n. Of the Cure of Hemorrhoidal Affections. DCCCCXLVIL Almost at all times it has been an opinion amongft phyficians, and from them fpread amongft the people, that the hemorrhoidal flux is a falutary evacua- tion, which prevents many difeafes that would otherwife have happened ; and that it even contributes to give long life. This opinion, in later times, has been efpecially Vol. IL Ff men- 442 PRACTICE mentained by Dr Stahl, and his followers ; and has had a great deal of influence upon the practice of phyfic in Germany. DCCCCXLVIII. The queftion arifes with refpecft to he- morrhagy in general, and indeed it has been extended fo far by the Stahl ians. I have accordingly confidered it as a general que- ftion, (DCCLXVH.-DCCLXXX.), but it has been more efpecially agitated with regard to the difeafe now under our confl- deration : And as to this, although I am clearly of opinion, that the hemorrhois may take place in confequence of the general ftate of the fyftem, DCCLXIX. or, what is ftill more frequent, that by re- petition it may become connected with that general ftate DCCCCXLIII. and in either cafe cannot be fupprefled without great caution; I muft beg leave, notwithftanding beg OF PHYSIC. 443 this, to maintain, that the firft is a rare cafe, that generally the difeafe firft appears as an affection purely topical (DCCCCXXXV. DCCCCXLIL), and that the allowing it to become habitual is never proper. It is a nafty difagreeable difeafe, ready to go to excefs, and to be thereby very hurtful, as well as fometimes fatal. At belt it is liable to accidents, and thereby to unhappy con- fequences. 1 am therefore of opinion, that not only the firft approaches of the difeafe are to be guarded againft, but even that when it has taken place for fome time> from whatever caufe it may have pro- ceeded, the flux is always to be moderated, and the neceffity of it, if poifible, fuper- feded. DCCCCXLIX. Having delivered thefe general rules, I proceed to mention more particularly, how Ff 2 the 444 PRACTICE the difeafe is to be treated, acccording to the different circumftances under which it may appear. When we can manifeftly difcern the firft appearance of the difeafe to arife from caufes acting upon the part only, the ftridl- eft attention fliould be employed in guard- ing againft the renewal of thefe caufes. DCCCCL. One of the moft frequent of the remote caufes of the hemorrhoidal affection, is a flow and bound belly, (DCCCCXXXVI.): and this is to be conftantly obviated by a proper diet, which each individual's own experience muft direct ; or, if the manage- ment of diet be not effectual, the belly muft be kept regular by fuch medicines as may prove gently laxative, without irritating the rectum. In moft cafes it will be OF PHYSIC. 445 be of advantage to acquire a habit with re- ipecl to time, and to obferve it exadlly. DCCCCLI. Another caufe of hemorrhois to be efpeci- ally attended to, is the prolapfus or protru- fion of the anus, which is apt to happen on aperfon'shavingaftool,(DCCCCXXXVII.) If it fliall occur to any conliderable degree, and at the fame time be not ealily and im- mediately replaced, it moft certainly pro- duces piles, orincreafes them when other- wife produced. Perfons therefore liable to this prolapfus, fhould, upon their having been at ftool, take great pains to have the gut immediately replaced, by lying down in a horizontal pofture, and preffing gently upon the anus, till the reduction fliall be completely obtained. Ff3 DCCCCLII. 446 PRACTICE DCCCCLII. When the prolapfus of which I fpeak, is occafioned only by voiding hard and bulky feces, it fhould be obviated by the means mentioned in DCt CCL. and may be thereby avoided. But in fome perfons it is owing to a laxity of the rectum; in which cafe it is often moft confiderable upon occafion of a loofc (tool: and then the difeafe is to be treated by aftringents, as well as by proper artifices for preventing the falling down of the gut. DCCCCLIIL Thefe are the means to be employed upon the firft approaches of the hemor- rhoidal affection; and when from neglcft it fhall have frequently recurred, and has be- come in fome meafure eftablifhed, they are no lefs proper. In the latter cafe, however, fome OF PHYSIC. 447 ibme other means are alfo neceflary. It is particularly proper to guard againft a ple- thoric ftate of the body ; confequently, to avoid a fedentary life, a full diet, and par- ticularly intemperance in the ufe of ftrong liquor, which, as I fhould have obferved before, is, in all cafes of hemorrhagy, of the greateft influence in increafing the difpofi- tion to the difeafe. DCCCCLIV. I need hardly repeat here, that exercife of all kinds mutt be a chief means of ob- viating and removing a plethoric date of the body; but upon occaflon of the he- morrhoidal flux immediately approaching, both walking and riding, as increafing the determination of the blood into the hemor- rhoidal veflels, are to be avoided. At other times, when no fuch determination has Ff4 been 448 PRACTICE been already formed, thofe modes of exer- cife may be very properly employed. DCCCCLV. Cold bathing is another remedy that may be employed to obviate plethora, and pre- vent hemorrhagy; but it is to be ufed with caution. When the hemorrhoidal flux is approaching, it may be dangerous to turn it fuddenly afide by cold bathing: but during the intervals of the difeafe, this re- medy may be employed with advantage; and in perfons liable to a prolapfus ani, the frequent waffling of the anus with cold water may be very ufeful. DCCCCLVI. Tliefe are the means for preventing the recurrence of the hemorrhoidal flux; and in all cafes, when it is not immediately ap- O F P H Y S I C. 449 approaching, they are to be employech When it has actually come on, means are to be employed for moderating it as much as poffible, by the perfons lying in a hori- zontal polition upon a hard bed; by avoid- ing exercife in an eredl pollute ; by uling a cool diet; by avoiding external heat; and by obviating the irritation of hardened faeces by the ufe of proper laxatives, (DCCCCL.). From what has been faid above, as to the being careful not to in- creafe the determination of the blood into the hemorrhoidal velfels, the propriety of thefe meafures mull fufEciently appear ; and if they were not fo generally neglected, many perfons would efcape the great trouble, and the various bad confequences which fo frequently refult from this dif- eafe. DCCCCLVII. 450 PRACTICE DCCCCLVIL With refpe6t to the further cure of this difetfe, it is almoSt in two cafes only, that hemorrhoidal perfons call for the afliSt- ance of the phyfician. The one is when the affection is accompanied with much pain ; and of this there are two cafes, ac- cording as the pain happens to attend the external or the internal piles. DCCCLV1IL The pain of the external piles arifes espe- cially when a conflderableprotrufion of the rectum has happened; and when, conti- nuing unreduced, it is Strangled by the con- ftridion of the fphinder; while, at the fame time, no bleeding happens, to take off the Swelling of the protruded portion of the inteStine. Sometimes an inflamma- tion Supervenes, and greatly aggravates the pain. OF PHYSIC. 451 pain. To relieve the pain in this cafe, emollient fomentations and poultices are fometimes of fervice ; but a more effectual relief is to be obtained by applying leeches to the tumid parts. DCCCCLIX. The other cafe in which hemorrhoidal perfons leek aifiitance, is that of excelTive bleeding. Upon the opinion fo generally- received of this difcharge being falutary, and from the obfervation that upon the difcharge occurring perfons have fome- times found relief from various diforders, rhe molt part of perfons liable to it are ready to let it go too far ; and indeed the Stahlians will not allow it to be a difeafe, unlefs when it has actually gone to excels. I am, however, well perfuaded, that this flux ought always to be cured as foon as poflible. DCCCCLX. 452 PRACTICE DCCCCLX. When the difeafe occurs as a purely to- pical affection, there can be no doubt of the propriety of this rule; and, even when it has occurred as a critical difcharge in the cafe of a particular difeafe, yet when this difeafe fliall have been entirely cured and removed, the preventing any return of the hemorrhois feems to be both fafe and pro- per. DCCCCLXI. It is only when the difeafe arifes from a plethoric Rate of the body, and from a (tag- nation of blood in the hypochondriac region, or when, though originally topical, the difeafe, by frequent repetition, has be- come habitual, and has thereby acquired a connection with the whole fyftem, that any doubt can arife as to the fafety of curing OF PHYSIC. 453 curing it entirely. Even in thefe cafes, however, I apprehend it will be always proper to moderate the bleeding; lefl by its continuance or repetition, the plethoric Rate of the body, and the particular de- termination of the blood into the hemor- rhoidal veflels,be increafed, and the recur- rence of the difeafe, with all its inconve- niences and danger, be too much favoured. DCCCCLXII. Further, even in the cafes Rated, (DCCCCLXL), in fo far as the plethoric Rate of the body, and the tendency to that Rate, can be obviated and removed, this is always to be diligently attempted ; and if it can be executed with fuccefs, the flux may be entirely fupprefled. DCCCCLXIIL 454 PRACTICE DCCCCLX1IL The Stahlian opinion, that the hemor- rhoidal flux is only in excefs when it oc- cafions great debility, or a leucophlegma- tia, is by no means juft; and it appears to me, that the fmalleft approach towards producing either of thefe, fhould be con- fidered as an excefs, which ought to be prevented from going farther. DCCCCLXIV. In all cafes therefore of excefs, or of any approach towards it, and particularly when the difeafe depends upon a prolapfus ani (DCCCLL), I am of opinion that aftringents, both internal and external, may be fafely and properly employed; not indeed to induce an immediate and total fuppreflion, but to moderate the hemor- rhagy, and by degrees to fupprefs it alto- gether, OF PHYSIC. 455 gether, while at the fame time meafures are taken for removing the neceflity of its recurrence. DCCCCLXV. When the circumftances (DCCCXLVL) marking a connection between the hemor- rhoidal affedtion and the date of the fto- mach occur, the meafures neceffary are the fame as in the cafe of atonic gout.
