Mr. Davis discovered signs of inflammation, after death from this

disease, to be universal. In eighteen or twenty dissections, he tells

us, he found the pia mater always distended with blood[55]. Where signs

of inflammation have not occurred, the blood-vessels had probably

relieved themselves by the effusion of serum, or the morbid action of

the blood-vessels had exceeded that grade of excitement, in which only

inflammation can take place. I have seen one case of death from this

disease, in which there was not more than a tea-spoonful of water in the

ventricles of the brain. Dr. Quin mentions a similar case. Here death

was induced by simple excess of excitement. The water which is found in

the ventricles of the brain refuses to coagulate by heat, and is always

pale in those diseases, in which the serum of the blood, in every other

part of the body, is of a yellow colour.

[55] Medical Journal, vol. VIII.

In addition to these facts, in support of the internal dropsy of the

brain being the effect of inflammation, I shall mention one more,

communicated to me in a letter, dated July 17th, 1795, by my former

pupil, Dr. Coxe, while he was prosecuting his studies in London. "It

so happened (says my ingenious correspondent), that at the time of my

receiving your letter, Dr. Clark was at the hospital. I read to him that

part which relates to your success in the treatment of hydrocephalus

internus. He was much pleased with it, and mentioned to me a fact which

strongly corroborates your idea of its being a primary inflammation of

the brain. This fact was, that upon opening, not long since, the head of

a child that had died of this disease, he found between three and four

ounces of water in the ventricles of the brain; also an inflammatory

crust on the optic nerves, as thick as he had ever observed it on the

intestines in a state of inflammation. The child lost its sight before

it died. The crust accounted in a satisfactory manner for its blindness.

Perhaps something similar may always be noticed in the dissections of

such as die of this disease, in whom the eyes are much affected."

Having adopted the theory of this disease, which I have delivered, I

resolved upon such a change in my practice as should accord with it. The

first remedy indicated by it was

I. _Blood-letting._ I shall briefly mention the effects of this remedy

in a few of the first cases in which I prescribed it.

CASE I.

On the 15th of November, 1790, I was called to visit the daughter

of William Webb, aged four years, who was indisposed with a cough, a

pain in her bowels, a coma, great sensibility of her eyes to light,

costiveness, and a suppression of urine, a slow and irregular, but

tense pulse, dilated pupils, but no head-ach. I found, upon inquiry,

that she had received a hurt on her head by a fall, about seven weeks

before I saw her. From this information, as well as from her symptoms,

I had no doubt of the disease being the internal dropsy of the brain. I

advised the loss of five ounces of blood, which gave her some relief.

The blood was sizy. The next day she took a dose of jalap and calomel,

which operated twelve times. On the 18th she lost four ounces more of

blood, which was more sizy than that drawn on the 15th. From this time

she mended rapidly. Her coma left her on the 20th, and her appetite

returned; on the 21st she made a large quantity of turbid dark coloured

urine. On the 22d her pulse became again a little tense, for which she

took a gentle puke. On the 23d she had a natural stool. On the 24th her

pupils appeared to be contracted to their natural size, and on the 30th

I had the pleasure of seeing her seated at a tea-table in good health.

Her pulse notwithstanding, was a little more active and tense than

natural.

CASE II.

On the 24th of the same month, I was called to visit the son of John

Cypher, in South-street, aged four years, who had been hurt about a

month before, by a wound on his forehead with a brick-bat, the mark of

which still appeared. He had been ill for near two weeks with coma,

head-ach, colic, vomiting, and frequent startings in his sleep. His

evacuations by stool and urine were suppressed; he had discharged three

worms, and had had two convulsion fits just before I saw him. The pupil

of the right eye was larger than that of the left. His pulse was full,

tense, and slow, and intermitted every _fourth_ stroke. The symptoms

plainly indicated an internal dropsy of the brain. I ordered him to lose

four or five ounces of blood. But three ounces of blood were drawn,

which produced a small change in his pulse. It rendered the intermission

of a pulsation perceptible only after every tenth stroke. On the 25th

he lost five ounces of blood, and took a purge of calomel and jalap. On

the 26th he was better. On the 27th the vomiting was troublesome, and

his pulse was still full and tense, but regular. I ordered him to lose

four ounces of blood. On the 28th his puking and head-ach continued;

his pulse was a little tense, but regular; and his right pupil less

dilated. On the 29th his head-ach and puking ceased, and he played

about the room. On the 4th of December he grew worse; his head-ach and

puking returned, with a hard pulse, for which I ordered him to lose five

ounces of blood. On the 5th he was better, but on the 6th his head-ach

and puking returned. On the 7th I ordered his forehead to be bathed

frequently with vinegar, in which ice had been dissolved. On the 8th he

was much better. On the 9th his pulse became soft, and he complained but

little of head-ach. After appearing to be well for near three weeks,

except that he complained of a little head-ach, on the 29th his pulse

became again full and tense, for which I ordered him to lose six ounces

of blood, which for the first time discovered a buffy coat. After this

last bleeding, he discharged a large quantity of water. From this time

he recovered slowly, but his pulse was a little fuller than natural on

the 19th of January following. He afterwards enjoyed good health.

CASES III. AND IV.

In the month of March, 1792, I attended two children of three years of

age, the one the daughter of William King, the other the daughter of

William Blake: each of whom had most of the symptoms of the inflammatory

stage of the internal dropsy of the brain. I prescribed the loss of four

ounces of blood, and a smart purge in both cases, and in the course of a

few days had the pleasure of observing all the symptoms of the disease

perfectly subdued in each of them.

CASE V.

In the months of July and August, 1792, I attended a female slave of

Mrs. Oneal, of St. Croix, who had an obstinate head-ach, coma, vomiting,

and a tense, full, and _slow_ pulse. I believed it to be the phrenicula,

or internal dropsy of the brain, in its inflammatory stage. I bled her

five times in the course of two months, and each time with obvious

relief of all the symptoms of the disease. Finding that her head-ach,

and a disposition to vomit, continued after the tension of her pulse

was nearly reduced, I gave her as much calomel as excited a gentle

salivation, which in a few weeks completed her cure.

CASE VI.

The daughter of Robert Moffat, aged eight years, in consequence of the

suppression of a habitual discharge from sores on her head, in the

month of April, 1793, was affected by violent head-ach, puking, great

pains and weakness in her limbs, and a full, tense, and _slow_ pulse.

I believed these symptoms to be produced by an inflammation of the

brain. I ordered her to lose six or seven ounces of blood, and gave her

two purges of jalap and calomel, which operated very plentifully. I

afterwards applied a blister to her neck. In one week from the time of

my first visit to her she appeared to be in perfect health.

CASE VII.

A young woman of eighteen years of age, a hired servant in the family

of Mrs. Elizabeth Smith, had been subject to a head-ach every spring for

several years. The unusually warm days which occurred in the beginning

of April, 1793, produced a return of this periodical pain. On the eighth

of the month, it was so severe as to confine her to her bed. I was

called to visit her on the ninth. I found her comatose, and, when awake,

delirious. Her pupils were unusually dilated, and insensible to the

light. She was constantly sick at her stomach, and vomited frequently.

Her bowels were obstinately costive, and her pulse was full, tense, and

so slow as seldom to exceed, for several days, from 56 to 60 strokes in

a minute. I ordered her to lose ten ounces of blood every day, for three

days successively, and gave her, on each of those days, strong doses of

jalap and aloes. The last blood which was drawn from her was sizy. The

purges procured from three to ten discharges every day from her bowels.

On the 12th, she appeared to be much better. Her pulse was less tense,

and beat 80 strokes in a minute. On the 14th, she had a fainting fit. On

the 15th, she sat up, and called for food. The pupils of her eyes now

recovered their sensibility to light, as well as their natural size. Her

head-ach left her, and, on the 17th, she appeared to be in good health.

Her pulse, however, continued to beat between 50 and 60 strokes in a

minute, and retained a small portion of irregular action for several

days after she recovered.

I am the more disposed to pronounce the cases which have been described

to have been internal dropsy of the brain, from my having never been

deceived in a single case in which I have examined the brains of

patients whom I have suspected to have died of it.

I could add many other cases to those which have been related, but

enough, I hope, have been mentioned to establish the safety and efficacy

of the remedies that have been recommended.

I believe, with Dr. Quin, that this disease is much more frequent

than is commonly supposed. I can recollect many cases of anomalous

fever and head-ach in children, which have excited the most distressing

apprehensions of an approaching internal dropsy of the brain, but which

have yielded in a few days to bleeding, or to purges and blisters. I

think it probable, that some, or perhaps most of these cases, might have

terminated in an effusion of water in the brain, had they been left

to themselves, or not been treated with the above remedies. I believe

further, that it is often prevented by all those physicians who treat

the first stage of febrile diseases in children with evacuations, just

as the pulmonary consumption is prevented by bleeding, and low diet, in

an inflammatory catarrh.

Where blood-letting has failed of curing this disease, I am disposed

to ascribe it to its being used less copiously than the disease

required. If its relation to pneumonicula be the same in its cure,

that I have supposed it to be in its cause, then I am persuaded, that

the same excess in blood-letting is indicated in it, above what is

necessary in phrenitis, that has been practised in pneumonicula, above

what is necessary in the cure of an acute inflammation of the lungs.

The continuance, and, in some instances, the increase of the appetite

in the internal dropsy of the brain, would seem to favour this opinion

no less in this disease, than in the inflammatory state of pulmonary

consumption. The extreme danger from the effusion of water into the

ventricles of the brain, and the certainty of death from its confinement

there, is a reason likewise why more blood should be drawn in this

disease, than in diseases of the same force in other parts of the body,

where the products of inflammation have a prompt, or certain outlet from

the body. Where the internal dropsy is obviously the effect of a fall,

or of any other cause which acts _directly_ on the brain, there can be

no doubt of the safety of very plentiful bleeding; all practical writers

upon surgery concur in advising it. The late Dr. Pennington favoured

me with an extract from Mr. Cline's manuscript lectures upon anatomy,

delivered in London in the winter of 1792, which places the advantage

of blood-letting, in that species of inflammation which follows a local

injury of the brain, in a very strong point of light. "I know (says he)

that several practitioners object to the use of evacuations as remedies

for concussions of the brain, because of the weakness of the pulse; but

in these cases the pulse is _depressed_. Besides, experience shows,

that evacuations are frequently attended with very great advantages. I

remember a remarkable case of a man in this [St. Thomas's] hospital, who

was under the care of Mr. Baker. He lay in a comatose state for three

weeks after an injury of the head. During that time he was bled _twenty_

times, that is to say, he was bled once every day upon an average. He

was bled twice a day _plentifully_, but towards the conclusion he was

bled more sparingly, and only every other day; but at each bleeding,

there were taken, upon an average, about sixteen ounces of blood. In

consequence of this treatment, the man perfectly recovered his health

and reason."

Local bleeding by cups, leaches, scarifications, or arteriotomy, should

be combined with venesection, or preferred to it, where the whole

arterial system does not sympathize with the disease in the brain.

II. A second remedy to be used in the second stage of this disease is

_purges_. I have constantly observed all the patients whose cases have

been related, to be relieved by plentiful and repeated evacuations from

the bowels. I was led to the use of frequent purges, by having long

observed their good effects in palsies, and other cases of congestion

in the brain, where blood-letting was unsafe, and where it had been

used without benefit. In the Leipsic Commentaries[56], there is an

account of a case of internal dropsy of the brain, which followed the

measles, being cured by no other medicines than purges and diuretics. I

can say nothing in favour of the latter remedy, in this disease, from

my own experience. The foxglove has been used in this city by several

respectable practitioners, but, I believe, in no instance with any

advantage.

[56] Vol. xxix. p. 139.

III. _Blisters_ have been uniformly recommended by all practical writers

upon this disease. I have applied them to the head, neck, and temples,

and generally with obvious relief to the pain in the head. They should

be omitted in no stage of the disease; for even in its inflammatory

stage, the discharge they occasion from the vessels of the head, greatly

overbalances their stimulating effects upon the whole system.

IV. _Mercury_ was long considered as the only remedy, which gave the

least chance of a recovery from a dropsy of the brain. Out of all the

cases in which I gave it, before the year 1790, I succeeded in but two:

one of them was a child of three years old, the other was a young woman

of twenty-six years of age. I am the more convinced that the latter

case was internal dropsy of the brain, from my patient having relapsed,

and died between two or three years afterwards, of the same disease.

Since I have adopted the depleting remedies which have been mentioned,

I have declined giving mercury altogether, except when combined with

some purging medicine, and I have given it in this form chiefly with a

view of dislodging worms. My reasons for not giving it as a sialagogue

are the uncertainty of its operation, its frequent inefficacy when

it excites a salivation, and, above all, its disposition to produce

gangrene in the tender jaws of children. Seven instances of its inducing

death from that cause, in children between three and eight years of

age, and with circumstances of uncommon distress, have occurred in

Philadelphia since the year 1795.

V. _Linen cloths_, wetted with cold vinegar, or water, and applied to

the forehead, contribute very much to relieve the pain in the head. In

the case of Mr. Cypher's son[57], the solution of ice in the vinegar

appeared to afford the most obvious relief of this distressing symptom.

[57] Case II.

A puncture in the brain has been proposed by some writers to discharge

the water from its ventricles. If the theory I have delivered be true,

the operation promises nothing, even though it could always be performed

with perfect safety. In cases of local injuries, or of inflammation from

any cause, it must necessarily increase the disease; and in cases of

effusion only, the debilitated state of the whole system forbids us to

hope for any relief from such a local remedy.

Bark, wine, and opium promise much more success in the last stage of

the disease. I can say nothing in their favour from my own experience;

but from the aid they afford to mercury in other diseases, I conceive

they might be made to accompany it with advantage.

Considering the nature of the indirect causes which induce the disease,

and the case of a relapse, which has been mentioned, after an interval

of near three years, as well as the symptoms of slow convalescence,

manifested by the pulse, which occurred in the first and seventh cases,

I submit it to the consideration of physicians, whether the use of

moderate exercise, and the cold bath, should not be recommended to

prevent a return of the disease in every case, where it has yielded to

the power of medicine.

I have great pleasure in adding, that the theory of this disease,

which I have delivered, has been adopted by many respectable physicians

in Philadelphia, and in other parts of the United States, and that it

has led to the practice that has been recommended, particularly to

copious blood-letting; in consequence of which, death from a dropsy of

the brain is not a more frequent occurrence, than from any other of the

acute febrile diseases of our country.

OBSERVATIONS

UPON

THE NATURE AND CURE

OF THE

_GOUT_.

In treating upon the gout, I shall deliver a few preliminary

propositions.

1. The gout is a disease of the whole system. It affects the ligaments,

blood-vessels, stomach, bowels, brain, liver, lymphatics, nerves,

muscles, cartilages, bones, and skin.

2. The gout is a primary disease, only of the solids. Chalk-stones,

abscesses, dropsical effusions into cavities, and cellular membrane, and

eruptions on the skin, are all the effects of a morbid action in the

blood-vessels. The truth of this proposition has been ably proved by Dr.

Cullen in his First Lines.

3. It affects most frequently persons of a sanguineous temperament; but

sometimes it affects persons of nervous and phlegmatic temperaments.

The idle and luxurious are more subject to it, than the labouring and

temperate part of mankind. Women are said to be less subject to it than

men. I once believed, and taught this opinion, but I now retract it.

From the peculiar delicacy of the female constitution, and from the thin

covering they wear on their feet and limbs, the gout is less apt to fall

upon those parts than in men, but they exhibit all its other symptoms,

perhaps more frequently than men, in other parts of the body. The remote

causes of gout moreover to be mentioned presently, act with equal force

upon both sexes, and more of them I believe upon women, than upon men.

It generally attacks in those periods of life, and in those countries,

and seasons of the year, in which inflammatory diseases are most common.

It seldom affects persons before puberty, or in old age, and yet I have

heard of its appearing with all its most characteristic symptoms in this

city in a child of 6, and in a man above 80 years of age. Men of active

minds are said to be most subject to it, but I think I have seen it as

frequently in persons of slender and torpid intellects, as in persons of

an opposite character. I have heard of a case of gout in an Indian at

Pittsburg, and I have cured a fit of it in an Indian in this city. They

had both been intemperate in the use of wine and fermented liquors.

4. It is in one respect a hereditary disease, depending upon the

propagation of a similar temperament from father to son. When a

predisposition to the gout has been derived from ancestors, less force

in exciting causes will induce it than in those habits where this has

not been the case. This predisposition sometimes passes by children,

and appears in grand-children. There are instances likewise in which it

has passed by the males, and appeared only in the females of a family.

It even appears in the descendants of families who have been reduced

to poverty, but not often where they have been obliged to labour for a

subsistence. It generally passes by those children who are born before

the gout makes its appearance in a father. It is curious to observe

how extensively the predisposition pervades some families. An English

gentleman, who had been afflicted with the gout, married a young woman

in Philadelphia many years ago, by whom he had one daughter. His wife

dying three weeks after the birth of this child, he returned to England,

where he married a second wife, by whom he had six children, all of whom

except one died with the gout before they attained to the usual age of

matrimony in Great Britain. One of them died in her 16th year. Finally

the father and grandfather died with the same disease. The daughter whom

this afflicted gentleman left in this city, passed her life subject to

the gout, and finally died under my care in the year 1789, in the 68th

year of her age. She left a family of children, two of whom had the

gout. One of them, a lady, has suffered exquisitely from it.

5. The gout is always induced by general predisposing debility.

6. The remote causes of the gout which induce this debility, are,

indolence, great bodily labour, long protracted bodily exercise,

intemperance in eating, and in venery, acid aliments and drinks, strong

tea and coffee, public and domestic vexation, the violent, or long

continued exercise of the understanding, imagination, and passions

in study, business, or pleasure, and, lastly, the use of ardent, and

fermented liquors. The last are absolutely necessary to produce that

form of gout which appears in the ligaments and muscles. I assert this,

not only from my own observations, but from those of Dr. Cadogan, and

Dr. Darwin, who say they never saw a case of gout in the limbs in any

person who had not used spirits or wine in a greater or less quantity.

Perhaps this may be another reason why women, who drink less of those

liquors than men, are so rarely affected with this disease in the

extreme parts of their bodies. Wines of all kinds are more disposed

to produce this form of gout than spirits. The reason of this must

be resolved into the less stimulus in the former, than in the latter

liquors. Wine appears to resemble, in its action upon the body, the

moderate stimulus of miasmata which produce a common remitting fever, or

intermitting fever, while spirits resemble that violent action induced

by miasmata which passes by the blood-vessels, ligaments, and muscles,

and invades at once the liver, bowels, and brain. There is one symptom

of the gout in the extremities which seems to be produced exclusively

by ardent spirits, and that is a burning in the palms of the hands,

and soles of the feet. This is so uniform, that I have sometimes been

able to convict my patients of intemperance in the use of spirits, when

no other mark of their having taken them in _excess_, appeared in the

system.

I have enumerated among the remote causes of the gout, the use of

strong tea. I infer its predisposing quality to that disease, from its

frequency at Japan, where tea is used in large quantities, and from the

gout being more common among that sex in our country who drink the most,

and the strongest tea.
