PUBUSHED BY THE
MEDICAL AND CHIRURGICAL SOCIETY.
VOLUME THE THIRD.
PRIMTED POR LONGMAN, HURST, SEES, ORME, AND BROWH,

^D VERTISEMENT.
The President and Councilj convinced
of the advantages resulting from the early pub^
lication of the Papers with which the Medicai
and Chirurgical Society may he favored, and
which may be deemed worthy of being laid 6e-
fore the Public, have lost no time in editing
this Third Volume of the Society s Transactions.
The utility of the pian of early pub/ication,
receives an important conjirmation from the
experience of the Royal Society, and some other
Scientific Bodies in this country ; and though
the President and Council by no means wish to
pledge themselves to the precise periods at which
future volumes may appear, (which must ne-
cessarily depend on the number, as well as the
import ance of Communications made to the So-
ciety,) yet they have every reason to expect,
that they will be able to publish a pari of a
Volume, if not a whole one, at the end of every
season.

During my residence in Walcheren, I not ònly
vìsited ali the hospitals, but inspèeted, with the
permi^slon of the Cominander ià Chief, the whol?
retums of the anny from the tìme of their disem-
barkation, in order to adcertain the progress and ex-
tent of the sdckness and mortality. The result of
these enquiries ìè what I now propose to commu-
nicate, and, in describing the nature, and detailing^
th^ ravagesf of the prevailing disorder, I shall bor-
row the greàter part of what I bave to say, from my
i^eial Communications.
I arrived in the island on the SOth of September,
and remaìned till the isth of October fi>llowing.
During my stay I sta,ted to the govemment, th^t I

Both these dìseases, however, had begun to sheir

but were then stili more so, in conseqa^ice of most

In the large and elegant city of Middleburgh, the
accommodations were excellent, as we had not oixly
the advantage of the hospitals formerly belonging
to the Dtttch and French troops^ but the spacious
and aìry warehouses of the Dutch £art India Com*-
pany : this having been formerly the great empo*
lium of Indtan commerce. Here I fbund no ty^

Itis evidentin the presentinstance, how necessary

1 foundmyself under the painM necessity, there-
fere, of stating, that the sickness on this island did
not diminish. It appeared from the latest general
weekly retutn, that therfe were two thirds of the
whole numerai strength òf the army incapable of
duty* • The . mortality durii^ the last fofur weeks
had been about 1000. Ali the battalìons Teiere afi
fected nearly.in ari equal degree ; and it.does not
appear^ that tbeir illness was connected with tbe nu^
lureof tliéir duty, or that it was owing to priva-»
tions or nèglect of any kind ; for those were equal-^
ly sickly, who had enjoyed the utmost ease and
comfort in cantonments, as those who hàd been^nr
gagefd in thè siege of Flusbing.
■ i .
Nor was this great sickiiess imputableto any thing
unfavourable in the weather at tliis seasoii^in cofm^
parison of former years. On the contrary^ the native
inhabitants affirmed^ that thèy w^ete then lesssicMy
than usuai at the same season of the yeàt, and théy
accounted for this, from the uncommoti quantity of
rain that had fàll^n the last two months : for tlirty
ON THE WALCHEKEN FEVEB» 5
^onsider it as fully establìshed by observalìon, that
the most sìckly years are those, in which there had
been great dfought ajid beat in the latter end of
summer and the early part of autumn j owing, prò-
bably, to the increased exhalatìbji, and the more
concentrated foulness of the stagnant W9.ter prò»
duced by these causes»
I found upon enquiry, that a like degree of sick*
ness prevailed among the French troops who occu-
pìed Hushing during thelast seven yéarsj and that
in former times, the Dutch troops, froin the horth*
era parts of the United Provinces, suffèred equally.
As the army had not sufFered either from the scan-
tiness and bad quahty of provisions, nor from
want of proper accommodation, nor from hardships
and fatìgue, it admits of no doubt, that the unfor-
tunate state of the army bere, was solely imputable
to the contaminatibn of the air from a soil the most
productive of deleterious exhaJations of any perhaps
in Europe, producing an endemie fever which has at
ali times been particularly severe upon strangers
in the autumnal months» I find also upon enquiry,
that though this is by far the most sickly season, the
residents of this and the neighbouring islands do
not ehjpy, at any season, the same degree of health,
as the inhabitapts of the more salubrious parts of
Europe,
From this statement, it -will be clearly perceived,

reach of human cofatrol. There were two fects,
however, which afforded some encouragement fot
the employment of artificial means, in còunteract-
ing the overpowering influence of naturai causes.
One was, that thosè belonging to the upper ordèrs
of society in Walcheren were always less affected
with its endemie fevers than the poorer inhabitants:
the other, that the British officers suffered less in
this campaign, thah the private men, as will be seen
by an abstract of the retums. As this latter must
be owing to tome circumstances òf superìor accom-
modation and diet, there was encouragement to
attempi some improvement in these respects,
though the situation of the common soldier was as
comfortable as belongs to his condition^ With this
view I suggested the use of stoves in the barracks
as well as the hospitals, in order to promote the dry-
ness, warmth, and purity of the air. I alsO repre-
sented» that considerable beixefit might arise from
the men being suppUed with a hot breakfast. It
may likewise be remarked, that those who i^lept in
the upper stories of houses, were less Uable to the
disease, and had it in a milder form, than those who
slept on the ground floors. The testimony of the
natives ìi in tzvor of Ihis obsérvation. We had a
striking confirmation of it in the visit we paid to
the party aceommodated at Fort Rammekins. Tò
the obsérvation of General Monnet (the French
general who commanded during the siege) with
respect to the gobd eflfect of a small quantity rf ar-
dent spirita in the moming, I may add a recoìti-

mendation of mixing pepper fteely with the brMh
and other articles of food.
There were, in the beginning of October^ wheii
I arrived, considerably more than one half of the
army sick, or convalescent in hospitals.. This
amóunt tras not owing merely to the numbers aceru-
ing from those who were dailytakenillj butwas swell-
ed ib consequehce of the small number of dis«
charges^ and the numbers of convàlescents waiting
for a passage to England ; for under the inflaence <^
theendemial air, recov^rieswere slow andimperfecti
and relapses very frequenta not only among the fex^
who were discharged^ but among the convalescents
at the hospital, some of whom, when apparently in
a &ir way of doidg well, would unaccountably drop
down dead* This made me urge the conveyance
pf such subjects to England, with as little deky as
possiblf • There were then 6000 subjects proper
for beirig transported to Englànd ; and I recom-
mended, in conjunction with Dr. Macgregor, th«
superintendant of the militàry hospitals^ that line
of batile ships, with their lower deck guns taken
out, should be sent from England for this purpose,
therè being at Walcheren only the means of con*
veyance for lOOOmen. This measurewas render-
ed fhrther nec&ssary, by the rapid accumulation of
«ck in &e hospitals, some of which were already
over-crowded, and, if liot rdieved, must in them-
selvès bave pròved a source of additional sicknes»
and ifiifection.
\
9 FACTS A)n> OBSERVATIOKS
One of the most important'circumstances in thoi
pperation of nqarsh miasma on the human body
is the power of habit in mitigating its influence.
The natives are not a robuat peoplé ; they are pf a
very wan and sickly hue, and bave ali suffered
more or less firom the bad air which they breathe.
The children of both s^xes ar§ very subject to glan-»
dular and abdominal coipplaints ; andtheadults, par-^
ticularly thòse of the lower orders, haye ali of them,
some time or other in the course pf their lives, la-
boured under the endemie intermitt^nt, They
are, however, infinitely less subject to intermittent
fevers than strangers, It was curìpus to repfiark, in
conversing with the natives, èven, persons of educai
tion, and medicai practitioners, that they would not
admit their country to be more uiihealthy than any
other ; and when they were asked to account fon
the great sickness prevailing among our troops^
they n^entìoned some frivolous circumstance in diet
and habits of life, but would allow nothing. to be
ascrìbedto the insalubrity of the air. However
unfounded this prejudice may be, it is strongly ex^
pressive pf the great difference in point of bealth
between natives and strangers. These strangersi
are also yarìously affected according to thè diatrict
from which they come. It wa» found, that of the^
Brìtish troops, the natives of inountainous cóun-
tries, and dry scila, were more frequently 9.ffibcted
than the natives of fiat and moist . districts. It ì%

not feir to compare the mortality of an army, with
that of the general populatión; for the lattar in-
cludes ali ages, sexes, and constitutions, whereas
the former consists of the robust part of the male
sex, in theprìme of life. The computation being
Iliade ori the like clafes, it would appear, that there
is a éotisiderably smaller rate of mortality than in
people óf the saine age in England; for according
to Simpsòn's tables, the mortality heré in men and
womén from 20 to 45 is at the rate of one in 50
tómmUy; but the annua! rate of it in this army, if
computed by the mqnth ending the 26th of August,
would be only 1 in 248.

Water in a state of stagnation, without any ascer-

via, and eiitirely unconnected with the nature of.
the soil.
An intelligent general officer on the expedition
to Egypt in the year 1 800, who had served in ali
climates, assured me,Nthat he had nowhere seen so
little sìckness and mortality from disease ; for sick-
iiess, even including the pisane, was less destruc-
tive than in any other country in which he had
served; so that there was here an exception to a
rule which holds everywhere else, that disease is
more fatai thau the sword ; for more were killed,
or died by wounds, thaii by sickness, including even
those who died (^ the plague. Nor can it be al-
legedy that humidity alone may bave the efFect of
producing intermittent fevera ; for the vapor of
pure ftesh water, when not in a state of long stag-
nation, is fmmd to be free from any bad efFectl upon
the greater.number of constitutions. It is remark-
able, that though much greater quantities of rain
fall in the western parts of England thim the east-
ern, the average in some counties of the former
being more than doublé of what it is in those of the
latter, yet it does not appear that health is in the
least affected by this circumstance ; and seamen,
even in the thickest fogs on the banks of Newfound-
land, for many days together, preserve their health
perfectly. This poison, therefore, is some principle,
with the natxure of which We are stili unacquainted.

productivé of agues nor any òther dkorder. I al-
lude to bogs or peat mosses. This is fully proved
in Scotland, but stili more in Ireland, where there
are immense tracts of this soil, without any hurtful
influence upon health. It might naturally be ex*
pected also, that the swamps round Venice would
be productivé of endemie fevers. This is not the
case i and it is probably owing to the water which
forms them, being sea-water.
The miasmata in Zealand, are more noxious than
the like exhalations in England; the intermittents
fn the former, being more violent, untractable, and
fatai, than those which occur in the fenny coun-
ties, in the eastern parts of our own country. I
estimate this violence, by. the high degree òf febrile
beat and delirium, by the excessive secretion of
bile, the want of distinct intermissions, and the
more frequent sweUings of the li ver and spleen,
these taking place in the course of a very few weeks,
which in England seldom occur but under a long
continuance, or from frequent relapses of the dis-
case.
The exhalations of the soil in tropical climates,
extend farther, and are stili more malignant than
those of Zealand. Ships at the distance of dOOO
feet from swampy shores, (a distance to which it
did not extend in Zealand,) and even farther, were
affected by the noxious exhalations, according to
my own obscrvations and those of others in the

22 FACTS AND OBSERVÀTIONS
It is evident that the severi ty of the symptoms,
in the Zealand fever, added greatly to the difficul-
ty of the cure ; and there could be no ópportunity
of eitìploying Peruvian Bark or other specifìc reme-
dies, till its violence had abated, and the redundant
bile had been carried off. The treatment of this
acute state, consisted chiefly in giving such reme-
dies as purged freely; and in selecting them, the
preferencewas due to those which acted most readily
on the liver and the bile, such as calomel ; those
which wére least heating, as the neutral salts; and
such as were best borne by the stomach, which, in
a great many cases, was extremely irritable. In the
course of the general inspection, in which my duty
consisted at this time, I had not myself an óppor-
tunity of directing and wat^hing the practical de-
tails of individuai cases ; but I had considerable
experience in this way, in my atten dance on offi-
cers in England, wha either brought the complaint
with them, or were seized on the passage, or after
their return to this country. •
One of the medicai controversies respecting the
cause of intermittents, is founded on the difference
of opinion on the question, how far the excess of
bile may be considered as the cause of them. It
certainly cannot, in correct language, be called the
cause ; otherwise every case of redundant bile, such
as the cholera morbiùSj would be attended or fol-
lowed by an ague.^ Certain it is, however, that
epidemie intermittents not only occur exckisively
ON the" WAECHERENT FSySB* 23
in those seascms in which an excessivè-.secrelion of
bile is most apt to arise, but every attack, whether
originai or relapsed, which I bave secn, bore evi-
dent marks of an excessive flow of this humor. The
true statement of the fact perhaps is, that-that state
of the body, in which there is the strongest ten-
dency to a copious secretion of bile, either from
the naturai constitution, or the season of the year,
constitutes a predisposition favourable to the action
of the poisonous exhalations*. There seems in this
sondething analogous to other facts mentioned in à
fbrmer paper respecting the Piagne and the Yellow
Fever, namely, that the human body is not liable
to be affected by them^ unless when predispòsed by
a certain temperature of the atmosphere. If the
attack of this disease depended merely on theqtian-
tity of the exhalations, they would be most frequent
in June and July, when the beat of the atmosphere
is bighest But th^re is a stili more decisive proof
of its depending.on that season, in which the secre-
tion of bile is most copious, from this fact, that
when those who bave imbibed the poison, are
transported into countries where the air isin a state
of greatest purity , it is in the autumnal months, that
they are most conmionly attacked. There was" a
very striking proof of this after the campaign of
North HoUand in 1779. In the follo wing year some
of the officers and men who had escaped the disease,
were taken ili in the autumnal months; and none
that I heard of, at any other season of the year.
24 FACTS AKD OB^BltVATiaKS
é
The greateat difficulties which occurred in the
cure òf thpse severe intermittents in their early
stageSy proceeded firom the great irritability of
^totnach, which rendered it very difficult to exhibit
either purgatives with a view to procure intermis-
sions, or bark in sufficient quantity after intermis-
sions had been procured. The best means, I found,
of obviating the first difficulty , was to purge with
ealomely which, besides the advantage ahready men-
tioned, is^ on account of its small bulk, swallowed
without repugnance, and, by its weight, is not
easily rejected after being swallowed; and in case
the^ stomach rejetted neutral salts, to assist its ope-
f aition by consideràble quantities of carbonated mag-
nesia given in effervescence with lemon juice. It
* , is sometìmes advisable to give mercury às an alter*-
ative« Ramazim * relates^ that a person affect^
with aii obstinate ague wàs oired by mercurìal fric*
tion administered for the lues venerea* The second
difficulty was obyiated by substituting opium and
àrsénic for bark. The stomachs of some patients
were reconciled to the bark, by administering it with
opiùm or magnesia ili effervescence, or both; to
òthers it was so insùperably offensive, that it couid
not be bome in any form, quantity, or eombination.
In these cases, the cure was effected by opium and
arsenic, along with such bitters and aromatics, as
the stomach would bear, Where the periodica!
paroxysms had not ceased, the tincture of opium
was given from 30 to 50 drops, in the iatermission^ ,

a few hours before ih^ expected hour of seizure,
accompanìe^ with as mueh liiubarb as would coun-
teract its restringent effects. Sometimes the first
administration of thìs stopped the paroxysm ^ bui
more commonly only s^Ueviftted it, apd did not stop
it till the second or third time. After the p^rpx*
ysms were rtopped, it was continued in ^mailer dose^
ai the former perio^ds ; andeltber bark, or, if the
stomach would not bear it, arsenici was given in
the intervals, till it might r^asonably be supposed
that the tendency to relapse had ceased. At this
perìod, carbopate of iron wa^ also given with 9afety
and advantage, and with stili more benefit at a more
adyanced period, in prder to obviate debility ànd
emaciatiòn, and to afibrd a stili greater sectirity
against relapse, when there were no remains of fé?
ver, nor suspicion of loc$l affection. I bave cured
intermittent fevers in which bark had &iled both in
the West Indiest, and in St. Thomas's Hospital,
with the oxide of zinc ; but I bave made little use
of Uiis remedy sìnce I became acquainte^ with the
superior powers of opium and arsenic.

immediate visible effect, so modify the constìtution,
that tnany montbs afterwardsj though the persoti
has been living ali the while in a pure air, an in-
termittent fever arises sometimes, without any vi-
sible exciting cause; but most frequently in conse-
quence of cold, fatigue, watching, privatìon of
some kind, or, as has been before mentioned, on
the return of the autunm. This, as has been ai-
ready remarked, was strik^ngly exemplifìed in the
troops who had servèd in the campaign in North
Holland in September and October, 1 799. Among
these, was an officer who carne to town to put him-
self under my care, in the month of August in the
following year. He belonged to an encampment
at Swinly near Windsor, a district not liable to such
complaints; and he informed me, that not only
himsclf, but others who had not been- affected in
Holland, had been seized with intermittents, and
that this disorder was confined to those who had
been in the abovementioned campaign. I was in-
formed in February, 1811, by a field officer, who
came home from Portugal on account of bad health,
that those men of his own regiment as well as of
others, who had served before in Walcheren, were,
upon the first exposure and fatigue, rendered unfit
for duty, chiefly by remittent fevers, so as tó leave
not more than a third part of them fit for service.
Here there was a propòrtion of sick, far abòve that
of the army^ in general. This tendency is stili
strOnger, if the person had actually suffered from
immediate exposure to these exhalations; a consi*

continuìng.the remedies for a considerable time af-
ter ali the symptmns of the complaint have subsi-
ded, and also of avoiding the exciting causes above
enumerated. ...

I had, in the course of this service, an opportu-
nity of observing the extent to which the noxious
exhalatìons extended, . which » was found to be less
than is, I believe, generally known. Not only the
crews of the ships in the road of Blushing were en-
tìrely free from this endemie ; but also the guard-
ships which were stationed in the nan'ow channel
between this island and Beveland. The width of
this channel is about 6CXX) feetj yet, though some
of the ships lay «much nearer to one shore, than to
the other, there was no instance of any of the men
or officers being taken ili with the same disorder,
as that with which the troops on shore were af-
fected*
I had an opportunity of farther proving and il-
lustrating this ohservation, in the service I was
sentHipon to Northfleet in the autumn òf the fol-
lowing year. The spot upon which it i^ intended
to erect the proposed dock-yard and arsenal, is a
marsh of about 700 acres. On the banks of the
river, both above and below it, there is soil of a
similar description, but not immediately adjoining
to it on either side ; for above is the village of
Green Hithe, which stands on a chalky bottom,
28 FACTS AND OBSBR^yATIONS
rising to a few ìnches below the surface, and
ìs a projecting point of the general chalky hills
which compose the adjacent country, Below it,
on the bank of the rìver, there. is a similar inter-
vetition of the chalk, where the village of North-
fleet stands. Both these are nearly on a level with
the marsh ; yet the intermittent fevets are almost
unknown at either of them, whereas they are ex-
tremely prevaleti^t on the adjacent hiUs. I found
this fact analogous to some others to which my en-
quìries at this time led me. Dr. Maton infonned
me, that in the neighbourhood of Weymouth,
though there is stagndting water near the sea> pro-
ducing intermittents, these disorders are not known
in the dry districts on each side, on a level with
the water, but prevail on the adjacent hills. A
Cornish gentleman stated to me, that at St. Bla-
zey, between St. Ausile and Lestwithiel, agues
prevail much on a hill adjoining to a marsh conti-
guous to the sea beach. And Major Rennel, the
celebrated geographer, says, that in a district which
he surveyed on the river Burrampooter, the waters
pf which overflow, and, upon retiring, leave an oozy
fiat, the agues prevail to the very summit of the
adjoining hills. Lancisi mentions a hiU, on which
the same sickness prevails, as in the marshy lands
at the foot of it"^. An instance of the same fact in
ìSt. Lucia, has been already mentioned.

It is known to éveiy one, évei^ so little acquaìnt-^
ed with the operations of nature, aind indeed the
conimon pheiiometià oP clouds and rain render it
obvious to the inost ordihary observer, that water,
recently exhaled from the surface of the earth, has
a Ttendency to ascend, and being lifted over parts
on thfe same ievel, impinges on the neighbouring
heights, TTiere is reason to believe that impure
and unwholesome particies in general are attracted
by watery vapors, for it is remarkable, that, in case
of fogs, oflfensive smells are perceived, which in a
dry state of the air were fixed and quiescent.
Though pure humidity, theiefore, is innocuòus, it
may prove pemicious as a vehicle of unwholesome
volatile matter. In like manner, ihe poiisonou
principle of marshes, whatever it is, being engen-
dered by moist soils, will naturally adhere to the
watèry vapors, and ascend with fhem.
There are facts to prove, that certaan artificial
cfaanges tend greatly to improve the air of particu-
lar spots. It is well ascertained^ by the records of
physic, by the bills of mortality, and by civil* his-
tory, that intermittent fevers were very prevalent
in London, before the formation of common sewers
and the adoption of other means, such as paving,
conducive to cleanliness and dryness, to which,
more perhaps than to the improved habits of lifè,
in poìnt of diet, may be ascribed the unexampled

90 FACTS AND OBSERVATIONS
State of health in this great metropolis. There is
a stili stronger proof and illustration of this in
Portsmouth, which is buìlt upon a fiat, composing
part of the marshy island of Portsea. I am assiìred
by a medicai gentleman who practised there, but
is now retired from practice, that when he first
knevz that place, intermittent fevers were very pre-
valent; but the town having been drained and paved
in the year 1769, that disorder has since been un-
known there*. Hilsea and other parts of the Island
of Portsea bave retained the same aguish character j
but this dìsease has greatly decreased there also,
since a drainage which was madé in the year 1 79S,
Numberless other examples might be addUeed in
proof of this, derived from the general improved
state of health in various parts of the kingdom, in
consequence of the inclosure of commons for the
purpose of. agricultural improvements, of which
draining is (me of the prìncipal. This has been felt
on the spot now in question, for I am assured by
the Rev. Mn Crackhilt, who has resided in the pa-
rish of Northfleet for 42 years, that there has been

ON THE WALCHEREN FEVER. SI
in that time a progressiva amelìoration in point of
health.
It is mentioned by Bishop Burnet, in his History
of the Reformation, that in the last year of Queen
Mary's reign, " Intermitting fevers were so univer-
sal and contagioùs, that they raged like a piagne;*'
and we learn from Sydenham and Morton, that in-
termittent fever was one of the most prevalent and
fatai disorders in London from 1661 till 1665, and
that for some years afterwards this cofnplaint was
very rare. This was probably owing to the grea^ter
dryness of the streets by draining, when the city
was rebuilt after the great fire of 1666. We are
told however by Sydenham, that intermittent fevers
revived before the end of that century, and were
epidemie from 1677 to 1685. They prevailed a
good deal during the first part of the 18th century j
and we learn from a work of Dr. Fothergill's, that
they occiured as an annual epidemie in the spring
and autumn, as late as the years 1751, 1753 and
1754. For more than 30 years past, according to
my own observation and the best ìnformation I can
gather firom others, this disease has not been known
as an epidemie in this metropolis. I was physician
to St. Thomas's Hospital, from the year 1783 till
1795, during which period, the whole number of
intermittents that fell under my care, was 192. As
there were three physicians, this may be reckoned
the third part of the whole admiss^ons for twelve
years in an hospital eontaining 400 patients. I
32 f ACTS AND OBSERVATIONS
bave aot noted in my journal, from what quarter
they carne; but my memory perfectìy warrants me
in aifirming, that the great majority of them were
labourers from marshy districts, particularly Kent
and Essex, and there is this internai proof of the
greater part being strangers, that, of the number
above specified, only SS were females. Had they
belonged to the resident popuWion, the num-
ber of each sex would bave been nearly equal. On
referring to the notes, which I keep of my private
practice, I find that in the course of 25 years, I
bave met with 63 intermittents. Of these, 1 2 be-
longed to the armies, that had served in Holland
or Zealand, and of the number affected in Eng-
land, more than one half came from the aguish
counties. Several of the cases of those who be-
longed to the resident population, were so slight
and irregular, as to render it doubtfìd whether they
werfe strictly referable to this gemcs of disease.
One of the objects prescribed to me on my visit
to Northfleet, was to ascertain how far the health
of that spot might be affected by the exiialaticms
from the Essex side of the river. What has been
already said on the subject relating to Zealand, af.
fords an ahswer to this question ; the width of the
chànnel between Walcheren and Beveland being
about sìx thousand feet, and the breadth of the
ri vèr at Northfleet, aecording to a pian in the pos-
session of Mr. Rennie the engineer, being three
thousand feet. The distance of Essex from the

bank of the river at Northfleet, is therefore about
the same as between the shipa riding in the middle
of the channel, between the shores of Walchereft
and Beveliind. I found, however, from the most
accurate enquiry, that the endemie fever had not
spread, either to the ships of war in the roads of
Flushing, or to those stationed between the islands,
though some of th^m were nearer the shore than
the middle pf the channeK
I was further informed by Mr, Rennie, that iq
borìng the ground at Northfleet, he found tliat
there were beds of chalk and gravel undemeath th^
clay, so that these materìals, when thro\m up in
makìng thp e^f^cavatìons, would render the surfaCe
dry and wholesome ; and that he had calculate4
their quantity would be such^ as to raise the arti-»
ficial suiface eighteen feet high^r than. the present
naturai s^rfacQ,
.Taking into consideration, therefore, the great
changes which would take p]ace in the marshy spot
on which it was proposed to erect the docks and ar.»
senals, in consequence of the excavations, thQ
draìnings, the pavings, buildings. and various other
operatipns for forges and other machinery, I gave
it as my opinion, that no solid objection, on the
3Core of health, would arise to the pian proposed,.

qf England and Wales ^ at dij^rent periods.
SiNCE the preceding article was submitted tp tìie
Society, the Speaker of the House of Gommons
has done the author the honor of sendìng him a
copy of the retums of the population and parìsh
registers, made in pursuance of an Act of Fadia-
ment past last year. From these, some interesting
ànd authentic information may be gathered respect-
ing the public health, particularly with regard to
the disease, which is the sufojectc^ this article.
It appears from these retums, that the mortalitgr
in England and Wales in the year 1810, was ab<mt
1 in 49, the whole population being 10,150,615,
and the number of burials 208,184, that the births
were in the proportion of 1 in 34, and iJiat every
10 marriages produced on an average 42 childre©.

The counties in which the mortaKty was abov«
the average, were Middlesex, where it was 1 in »6;
Kent, where it wias 1 in 41 ; Warwickshire, ^er«
it was 1 in 42 ; Cambridgeshire, where it was 1 in
44;' Essex, where it was also 1 in 44; Surrey,
where it was one in 45 ; the East Riding of York*

was 1 in 48. 0£ the^e eight counties, four are sub*-

shire) aiu} the £ast Bidiog of Yorkshire, comprìs-
iiig aU the counties of that descrìption, except Lin-
colnshire, in which the mortality is below the aver^
age, being 1 in 51. The ^mailer degree of lior*
tality ii9i tìm last, is no doubt owing to the great
proportion^ which the dry and upland part of it
J>ears to the fenny districts. That there is a great
diflEerence in the mortality in these, is proved by
their respective return». Hie mortality in the
town of Boston, for instapce, which is situated in
the fens, is l in 97 } whereas that of Stamford,
which is in the diy and upland division, is l in 50.
And bere it may be proper to advert to an observ-
ation grounded on a very satisfactory induction of
&^ts, in a tract lately published, of which Dr.
Wells is the authpr*, thàt Hithisis Pulmonalis is
but little known in those districts which are infesta
ed with the exhalations producing intermittent fe*-
yer$. But as Phtbisis Pulmonalis forms one of the
principal heads in the general mortality of England,
so n)ucb the more is to be imputed to intermittents,
in those districts in which they are endemie.
It may be asked, whence arises the greater mor.
tality of the other fibur counties, of which tlie rate is

above the average. With regard to Middlesex, it fe
imputable no doubt to the varioùs circumstances ad-
verse tohealth, peculiar tothe metropoli», such as
the more intemperate habits of life, and perhaps
stili more the unfàvorable influence^ of the air of
thÉ great city, particularly on young childi-en. It
is worthy of remark, howevèr, that London has of
late years been improving in salubrity ; for it ap-
pears by the bills of mortality , that the burials in-
variably and considerably exceeded the christen-
ings, till a few years before thè dose of thè last
century : whereas since that time the christenings
bave generally exceeded the burials. This may
in part be ascribed to vaccination ; but it cannot
be entirely owing to this cause, for the decrease of
burials took place some years before that admirable
discovery. The first year on the records of the bills
of mortality, in which the births exceeded the bu-
mls in this metropolis was 1790. The decrease in
the deaihs of cliildren under two years of age, is
the most striking point of difference in these
tablep. In the beginning and middle of last cen-
tury, their annual amount fluctuated from nine to
ten thousand. Towards the end of last century,
and duringthat partof the present which has elapsed,
théy bave fluctuated from five to six thousand: and
considering that the computed riumber of inhabit-
antsiu 1700, was only 674,350, and in 1810, by
the late enumeration it is 1,050,000: it is evid^nt
that the relative mortality in this class, is little
more than one third of what it was a hundredyear^
ENGLAND AND WALES. 8t
ago. In farther probf of tìie improving health of
London, it is. stateci in this Parliamentary Report,
that the annual mortality in 1700, was one in 25 ;
in 1750, one in 21 ; in 1«01, and the four prece-
ding years, one in 35} and in 1810, one in 38.
The increased mortality in the middle of last (!%n-
tury, has been imputed to the great abuse of spi-
rìtuous liquors, which was checked about that time
by the imposition of high duties. The other causes
of superior health, seem to consist in ageneì^al im-
provement in the habits of life, particularly with
regard to ventilation and cleanliness, greater abun-
dance and better quali ty of food, the improved
state pf medicine, ^nd thp better management of
children»
The high proportion of mortality in Surrey, is
no doubt owing to its containing a portion of the
metropolis consisting of a population of 170,000,
which is more than one-half of the whole county.
The high rate of mortality in Warwickshire,
si^ems at first sight the most difficult to be ac-
counted for, the air of this part of the kingdom
I^eing very salubrious. It is no doubt owing to
the town of Birmingham being situated bere, for
it comprises two-fifths of the population ; and the
qiortality on the average of the last ten years, i&
one in 34. The mortality in this town is greater
than in Manchester, Leeds, or Norwich, the ope-
tatiótiÈ iti metaU, being probaMy mòte pemicioitar
to health, than the operatians of weavi^g^.
With regard to Lancashite,- where thè mdrtality
ìs Somewhat above the average, the nitmber of large
towns and extensive maniifkctures, affording a
greater proportion of artisans, to niral inhabitants,^
than in any other county, except those in which
the metropolis is situated, is certainly the cause of*
this, for the air is very salubrious, and the great
quantity and cheapnessof fuel, is extremely friend-.
ìy to life, health, and comfort. The repott of
Manchester, which is the second town in England
in point of population, forms an exception to this
remark, for the mortality there on the average of
the last ten years, is one in 58, and in the year 1810,
one in 74. But that of Liverpool, is one in 34 on
the average of ten years, an<Ì one in SO, in the
year 1810. In the former we have another pleas-
ing pictur^ of the progressive improvement of
health, for it is stated by the late Dr. Perei vai,
that in the year 1757, the annual mortality of
Manchester, was one in 25.7, and in 1770, one in
28 ; although at the former period the populatioit
was not quite one-fourth, and at the latter period,
not one-half of its present amountt. This im-
provement of health is greatly imputable to certain
regulations of police, particularly with respect to
'^ * See Ramazini de Morbis artìfìcum.

ventilation^ recommeaded and introduced by the
above mentìoned benevolent, enlìghtened, and ac»

The like progressive ameliòration of health, is
deducible from these public documents with respect
to the whole kingdom, as has been remarked lo-
cally ; for it appears from the returns of 1800,
that the mortality of alt England and Wales was
fhen one in 45; but in 18 IO, it proves to be one
in 49.
Thìs statement of facts cotrpied tvith the general
result of the population returns, from which it ap-

Read December 24, 181 L
On May 81, 1811, I was requested to vìsit
Maria Grant, a young woman, 23 years of age, of
a spare habit, who Was confined to the house by
ovarian dropsy, which had enlarged the abdomen
to a size very far exceedìng any thing of the kind
I had e ver seen. The disease began about six
years before, by a tumor in the left side, unaccom-
panied by any derangement of her general health,
which was even now very good, exceptmg only that
she had not menstruated for two years past, and
that the secretion of urine was scanty. Dr. Sim-
mons hadfrom time to time prescribedfor her; but
as medicine was not productive of any advantage,
he wished me to see ben

point of the ensiform cartilage ta the top of thè
pubìs. Thelegs were oedematous; the leftconsi*
derably more so than the right ; and great part of
the skiiì^of the left leg was in a state of complete
ìchthyosis. The lower part of the belly was also
oedematous, and the navel, when she sat, was on a
line wìth the knee.
The enormous qtiantity of fluid accumulated^
made it appear to me improper to think of evacua*
ting tlie whole at once, and I judged it best that thp
first evacuation should be made in a very graduai
manner, lest a hasty diminution of the tension should
produce syncope, and occasion too great a disturb-
ance of the system. I called therefore on the fol*
lowing day, June the first, accompanied by Dr.
Merrìman and Mr. Copeland, and made an oblique
puncture with a lancet at the most prominent part
oftheabdomen, in the linea alba, six inches above
the navel j and introducing a director, evacuated
seven gallons and a half of very dark, coffee-co-
loured fluid. When this quantity had beeh dis^
charged, she began to feel somewhat faint, and I
immediately closed the puncture with adhesive
plaster and graduated compresses. The abdomen
was stili tense, and measured S5\ inches in cir-
cumference, and 31^ from the ensiform cartilage
to the pubis.
She pàssed a good night, and on the foUowing
^yappeared liàuch relieved. The bowels acted

properly without any assistance firom medicine ;
and she passed near twice as much urine in 24
hourg, as she had been accu&tómed to do for severa!
years before, and this increase in the secretion of
urine contìnued.
June the eìghth, the enlargement appeared to bé
considerably more on the left side. The abdomen
measured 54inches round, of which SO inches were
from the spine to the middle of the linea alba, on
the lefl side, and 24 inches on the right. From the
point of the ensiform cartilage to the pubis weré
80 inches, so that a diminution of an inch and an
half in eadii direction had taken place in the inter-»
vai between the operation, and this perioda I now
xnade a second puncture in the most prominent
part of the lefl side, and dìscharged four gallona
and an half of straw-coloured, topy fluid. She
then became languid, and the optning was dosed
as before. The abdomen now measured 4S^ inches
round, and 27 from the ensiform cartilage to the
pubis: a bandage was applied.
No disorder was occasioned by this puncture»
The parietes of the belly gradually contracted »•
as to render it less flaccid ; the quantity of urine she
passed was as much as she had ever used to void
before the disease commenced ; and the size of the
belly contìnued to lessen, so that on the 27th of
June the circumference was only 45 inches^ and
the distance from the ensiform cartilage to the pu-

trocar used for pnnctwing the bladder through the

took except gruél, was rejected, or followed by-a
stool. Medicines gave only a temporary and imper-
feci relief, for she Innguished in this state> with few
material variations, till the sixth of September,
which was the day of her death. The abdortien had
fora time become enlarged during this.interval, but
had greatly subsided again. Its circumference then

however become extrfemely emaciateci, 'l'he cir-

On examining the body after death, the whole ca«*
vity of the abdomen appeared to be occupied by
two large cysts, formed in the lefl ovaiium, closely
connected together, their coats being of a very
firm texture, particularly the lowér one, which was
much the largest and thickest. They both adhered
anteriorly and laterally to the parietes of the abdo-
men, so as to require considerable force, and some
dissectioh, to detach them. The upper cyst con-
fained about 2 quarts of a brown glairy fluid, like
that which had been evacuated in the first opera-
tion, with some loose flakes of coagulable lymph.
The inferior cyst contained 3 gallons of .purulent
fluid. Its inner surface was covered with coa^able
lymph, having in it many large dark red spots.

ovarìuHì, one contaìning about 4 ouhces of a soft
gelatinons substance, and the other about half aa
ounce. The right ovarium and the uterus were in
a perfectly healthy state.
The right kidney had entirely lost its naturai ap*
pearance, and was converted into a sac, having two
distinct cavities, fiUed with a. straw-coloured fluid,
and having no opening into the ureter. The left
kidney and the rest of the viscera were sound in
their texture. But the liver ^as unusually sinalL
The whole of the abdominal viscera were forced
upward ; encroaching on the cavity of the thorax
so much, that the summit of the diaphragpi was on
a line with the upper edge of the thitd rib,
This case appears to me to afford several Inter-
estiiig particulars. A very obvious one, is the enor-
mous quantity of fluid accumulated. For as the
size of the abdomen diminished between each ope*
ration, the secretion of urine being in the mean
tirae increased, I am certainly warranted in as-
suming, that at least a quantity equal to the whole
which was drawn off in the four operations, had
been coUected in the belly at first. This, it will be
found, amounts to seventeen gallons ; a quantity, I
believe,far exceeding that of any.otlier case on re-
cord. And if any allowance is to he made for the
diminution of size between the operatioijs, it would
appear that the originai quantity must have been
even considerably more than I have now stated.

It is also singular that so very large a cdlectioA
€£ fluid sfaould be formed without any jdLerange*-
aient of the general heakb, for the bowels had ali
along continued their action as regularly as usuai*
The breathing and pulse too were unaffected, not-
witbstaading so great an encroachment on the ca-
pacity of the thorax. In short almost the whol^
ìneonvenience ^e appeared to sustain fròm the dis-
ease was the excessive weight she had to carry.
Another cireumstance worthy of remark, is tlie
progress of inflammation and suppuration in the
larger and inferior cyst, to which ber death is to be
escribed. That cyst, near a quarter of aa inch in
thickness, and as compact in it^ texture as parch-
tnent, was entirely insensible ; but it was most curi-
ous to observe that the process of inflamxnatiou
•sfaould be excited init, and go on to so large a col^
iection of pus, attended with a rapid decay of the
gerieral healdi, and showing by that, the sympathy
of the constitution with this adventitious substance,
^tbout pain or tendemess being excited in it, or
the neighbourìng parts ; for no mark of infiammai
tian whatever was discoverable in the peritoneum,
or in s^ny part exterior to this cyst ; and as I bave

48 DIFFICULT PARTURITION
tended severa! years ago, which will, I think, throw
some light on Mr. Park*s paper*
December 20th, 1804, I was requested by my
friend, Mr. Robertson, surgeon, then residìng in
Half-Moon Street, Piccadilly, but now at Great
Hindred in Berkshire, to see a poor woman in la*
bour, to whose assistance he had been called the
preceding evening. I learnt that she was about
forty years of age, that she had been delivered of
ber first child in the country, eight years before,
since which she had never been pregnant till now,
Her health was not very good, and she was very
apprehensive respecting the result of her labour, for
her fdrmer one had proved very long and difficult,
though the child was extremely small. The child
bowever was bom aJive, but died fn a fejv hours,
Mr. Robertson informed me, that the Liquor
Amnii had beeu evacuated before he was sent for,
and that the labour had made very little progress
during the last eight or ten hours, though the
£ains had been very frequent and severe : he like»
wìse told me that there was a tumor of an un-
common nature in the vagina, on which account,
principally, he wished me to see the patient,
Having introduced my finger within tke vagina,^
I felt a soft elastic tumor, which seemed capable
of containing four or five ounces of fluid : it was
compressible, and did not give the sensation of

fluctuation under the finger, but rather felt as if it
were a large pouch, formed by the coats of the
rectum pretemati^ally distended. On passing my
finger beyond this tumor, I felt the child's head
within the os uteri, which was thick, rigid, and
very little dilated. I was not unacquaìnted with
the fact, of tìie ovaria in a diseased state having
been occasionally found lyìng between the rectum
and the vagina, and it occurred to me that this
might be a case of that kind ; but I must confess,
that I too readily abandoned this idea, being pre-
possessed with the opinion, that the disease was
situated in the coats of the rectum.
From the state of the os uteri, it was apparent
that nothing could be safely undertaken towards
efiecting the delivery of the patient at present ;
but as there was great reason to believe, that the
bowels were much loaded, we determined to emp-
1y them by castor oil and clysters, and afterwards
to give a large dose of laudanum, in order to
quiet the pains, which teazed the patient exces-
Mvely, without producing any advantage. By
tìiese means very copious evacuations from the
bowelswere produced,and some sleepwas procured;
but the OS uteri remained undilated, and the bulk
of the child's head was stili shove the superior aper*
ture of the pelvis.
It will be unnecessary to state minutely ali the

52 DIFFICI7LT PAETURITION
presence of twins in the uterus might likèwise
prevenfe fhe full efFect of the pains ; but I imagine,
that the position of the diseased ovariùm, more
than any thing else, prevented the expùlsivè et
forts of thè womb ; not becàuse it proved an ob-
staclè to the birth of the child, (for the child did
not come in contact with thè tumor till after the
perforator had been used,) but by pajralysing, if I
may so express it, ali regular uterine action.
The fatai terniinatìon of this case made me re-
solve, should another of the samé kind qccur in
my practìce, that I would endeavour to evacuate
the contents of the tumor, by puncturìng it
through tìbe vagina, and I am well pleased to fìnd
from Mr. Park's cases, that this may bè done with
so great a probability of success. It must how-
'ever be récoUecfed, that ovarìan tumors not con-
taining a fluid, may sometimes be found in the
pelvis. I bave in my póssession, a preparation
consistìng of the ovarium enlarged, and filled
with fatty matter intermixed with hair, which has
formed to itself a bed, between the Vectum and
the vagina. Had the woman from whom these
parts were taken, become ìmpregnated, the ova-
rium must of necessity bave been confined in this
situation, and a tumor occupying a cònsiderable
space, must in consequence bave been forméd in
tlie pelvis, which would bave pròved a great ob-
stacle to parturitìon.
FROM DEOPSICAL OVARICM. 5&
A case of this kìnd has lately occurred in one
of the Lying-ìn-Hospitals of this city, as I was in-
r
formed by a surgeon, who was present at the dis-
section. The birth of the child having been long
delayed by a tumor in the vagina, it was deter-
mined to lessen the child's head, and the won^tn
was delivered, but did not long survive. After
death it wais ascertained, that the tumor was oc»
easioned by the ovarium filled with fatty matter
intermixed with hair and teeth, lying between the
vagina and the rectum.
In Baudelo^que's " Art des Accouchemens/*
5 196S, a similar, and, as he supposes, asolitary^
case of diseased ovarium in the pelvis, impeding
the birth of the child, is recorded. It had been
proposed by Lauveijat, and another accoucheur
of Paris, tò perform the Cjaesarean operation, as.
the only means of delivering the woman* Bau-
delocque objected, and recommended delivery by
the feet. After several ineffectual attempts on the
part of the other accoucheurs to turn the child, by
which the tumor was dislodged, and forced above
f the brìm of the pelvis, Baudelocque succeeded in
bringìng down the feet, but was obliged to bave
recourse to the forceps, in ordex to accomplish
the delivery of the head. The child was dead
born, and the woman died in two days. On open-
ing the body, the tumor was found to be occa*
sioned by. the ovarium enlarged, and filled with

fined and imbedded position in the pelvis, th9
safety of both motlier and child might be prG«
moted by tlie operation, It must be considered»
that the forceps or the lever can very farely ba
eniployed with efFect, when the vagina is thus pro^.
traded by a tumor behind it ; the only instruments
that we can look forward to, are the perforator
and hook ; the use of which presupposes the death
of the child, if not its actual sacrifice, at the mo-
ment of émploying theni. And with regard to
the mother, theae instrutnents cannot be had re-
course to in such cases, without exposing her life
to great risk, as has been proved in several in-
stances. Besìdes the two already mentioned, in
both which the mothers died, a similar case is re-
lated by Dr. Denman*, where the same fiital event
followed the use of the perforator.
Nor does it appear, that tuming the child, and
delivering by the feet, is safer practìce, as is proved
by Baudelocque's case, and likewise by one some-»
what similar, attended by Doeverent, in both of
^ich the mothers and children perished. Upon
• the whole, therefore, I am disposed to believe,
that where the tumor in the vagina occupies a
large space, it would be a more warrantable prac-
tice, to remove it by excision, if it consisted of a

A PREPARATioK of dlseased appendix vermiformis
in my possessione was removed &om a boy about 5
years of age who died under the following circum-
stances.
He had been observed for some time, to decline
in health) bui made no particular complaint, until
two days before bis death, when he was suddenly
seized wìth vomìting, and great prostration of
' strength. The abdomen became very tumid and
painfiil upon being pressed : bis countenance pale
and sunken, and bis pulse hardly perceptible.
Beath, preceded by extreme restlessness and deli-
rium, took place within 24 hours.
Upon examination, the whole surfàce of the pe«

thin coat of coagulable lymph ; and sHght adhe-
sion had taken place between the peritoneum co-
vering the viscera, and the parietes of the abdomen.
The viscera, independent of the inflammatìon of
their peritoneal covering, appeared in a perfectiy
healthy state, excepting the appendix vermiformis
of the coecum. Nò diseased appearance was seen
in this part near to the coecum; but about an
inch of its extremity was considerably enlarged
and thickened, its internai surface ulcerated, and
an opening from ulceratiqn, which would bave ad-
mitted a crow quill, was found at the commence-
ment of the diseased part^ about the middle of the
appendix, through which it appeared, that a tìiin,
dark coloured, and highly fetid fluid, had escaped
into the cavity of tlie abdorawi.
Upon opening the appendix, a piece of harden*
ed foeces was found impacted in that part of it
which lay between the opening, and that portion of
the appendix, which wias not evidently marked by
disease.

bis mother first perceived that^the lefl testicle was
rather larger than the rìght From this period ìt
gradually encreased until it attained the bulk which
ìt exhìbited when she carne to consult me. She
had applied to several siLrgeon$, who recommend-
ed leeches, poultices, mercurìal ointment, &c. &c.
without producing any visible amendment. The
case had been twice mistaken fot a hydrocele, and
thetesticle had been punctured wìth a trochar, but
no fluid followed. Very little inflammation sue-
ceeded the operations, and the disease did not ap-
pear to bave been materially aggravated by them.
At the time when I saw the child, bis testicle was
rather larger than a goose-egg, and, when unsup*
ported, reached tò the internai condyle of the femur.
It was of an ovai figure, with a regular smooth sur-
face, and when pressed had an elastic feei, so as to
produce the sensatìon of a fluid contained in a cyst:
so deceptive was the feel, that a gentleman, who
has had most extensive practice in the treatment of
hydrocele, pronounced it without hesitation to bc
a case of that description. It was not, however, in
the sÙghtest degree diaphanous ; and at the same
time, was much heavier than a similar bulk of wai*
ter. No testicle or epidid3rmis could be traced at
the posterior or inferior part of the tumor. The
child had a most unhealthy aspect; bis skin was of
a greenish yellow colour, and bedewed with a clam-
my moisture; bis muscles flaccid and diminished in
sizej his head was large and prominent in front,
bis eyes heavy, and pupil dilated, the iris being of

culty distinguished from the pupiL His respiration
was rather anxioua; he was troubled with cough
and had a frequent hard piilse. The abdomen was
large and tense, and he was habitually costive. I
ordered him Hydrargyri submurìatis gr. iìj. Jalapas
gr. yj. omni alterna nocte, and a lotion consisting of
liquQiis ammonite acetatis, aquas fontanae a a j^ iv.
to be constantly applied to the part during the day,
and a bread and water poultice at night. He con-
tinued the use of these medicines foraweek, with-
out any alteration in the state of the testicle, his
cough was rather better and his abdomen was soft-
er. As the disease had existed for nine montha,
and had rèsisted ali applications, I did not think
that any good would arìse from prosecuting these
measures, and much evil might be expected from
the delay which they would necessarily occasion.
I therefore thought it my duty to propose an ope-
ration, although from the unhealthy appearance of
the child, and the unfortunate result of similar
cases, I was not very sanguine of ultimate success ;
stili Jhòwever I was led to entertain some hope from
the cìrcumstance of being able to trace the sperma-*
tic cord distinct and free from disease, for nearly
an inch above tìie tumor, and from the inguinal
glands being perfectly healthy and naturai.

an unusual occurrence; It will, I trust, be ex*

dissection which the termination of the case af*
forded. Although this is not a very rare disease
in the testis, it appears that its diagnostic symp*
toms are not very well defined, nor its nature ge-
nerally known, as many cases are on record where
surgeons of great and deserved reputation hav^
inadvertently plunged their trochars into the 3tib-
stance of the tumòr. Fortunately, no material in*
jury is likely to accrue to the patient from such ari
operation ; but the surgeon will be liàble to much
censure for bis mistake. It is certainly difficult .to
determine the nature of some cases ; but there are
generally sufficient characteristic marks to enable
a practitioner to form an accurate judgment. The
regular ovai figure, the peculiar elastic feel, and
total \vant of transparency ought certainly to raisé

mispicions in a person's mind, which shbuid t^i»
der him cautious in giving bis ojnmon. Uhd^ar
these circumstances no man shòuld attempt to'
piwicture the tumor, without being fully prepared
to follow up the operation, by removing the testi-
eie in the event of there being no collection of •
fluid ; but any one who has been in tlie habit of
€omparin^ the two diseasés, will find rauch diffeiv
encef'even in the serisation imparted to bis touch.
To say «in what this diflference consists, I will not
attempt,. as it is almOst imipossible to ^express in*
woxds those njce powers of discrìmination which
ean only be gained by experience. An altention
to the. bistory of the case, ar^d to the state of
health, which always suflfers more or less, will be
of much assistance in forming an opinion. The
term fungus hagmatodes has been applied to this
disease, but upon what principle I ain at a loss to
éetermine, as there does not appear to be any dis*
position to the production of fungus, nor any
oozing of blood whten it is wounded, What the
naturai termination of th^ disease wpuld be, sup-
posing it ta exkt alóne in the testicle, Jias npt, as
iàr as I know, been yet cjetermined. It generally
spreads to p^rts ess^ntial to life, and d^stroys be-
fore the ulcers^tive ^tage has commenced. The
term jnedullary sarcoma is perhaps equally ^xcep-
^coìable, as it does not convey a correct id^a of the
disease in differept parts of the body^. In the

term fbunded on the appearance of this dìsease»
in any one part, must necessarìly convey a wroDg
ìmpressìon of ita nature in other parts» as ìt is cer*^
tainly much modified by its situatìon. I bave con»
sidered this case as worthy of being recorded, as
it ahows in a striking manner to what extent a dis.
ease may reach in so important an organ ^s the
brain^ without materially deranging its functions,
provided its progress be graduai. This is the more
to be wondered at, when wé consider that a total
auspension pf its powers, and even death, will
3ometimes ensue from so slight a derangement of
ita structuxe, as ahnost to elude the investiga'tions
pf the anatomista I had oc^asion to qiake this same
remark about two ^ years since, in a case of hrge
abscess in the brain, which was ^ot at ali suspect-
ed during life. An account pf this case yrss pub^'
lished in No. 132 of the Medicai and Pbysicat
Journal. I consider the terminatìon c^ this case
as a good illustration of the graduai loss of power
in the brain, when labouring under the eflfects of
disease. It is first incapable of transmitting its in-*
fluence to tlie extreme parts of the body, as the
disease advances it$ powers gradually diminisb,
and the extent of its influence diminishes in pro-
portion, those parts nearest th^ brain being last af-
fected. It is probable fhat a less morbid state of

gnosìs, that I take the liberty of oflFering to thq
Society a few particulars of four cases, which
have come under my observation within a veiy
short time. They will forni a proper sequel
to the preceding very interesting narrative of
Mr. Earle,
CASE I. — M. Lambertini, an Italiana about
thirty-five years of age, perceived a hard tumor
in the right breast about fifteen months hefore his>
deat^i. When this had existed about twelve months^
it ulcerated, and a . fungus' shòt up. I saw hinx
about three weeks before his. death, 'at which time.
there was an ulcerated and fungous surf^ce of
about two inches in circumference, on t^e right of
the Tight nipple, which was sound. One consider-
able protuberance in this surface was ulcerated,
nearly smooth and florid: the rest wa,s irregular
and tuberculated, and covered mostly wtli an un-
healthy cuticle. The discharge was not consider-.
able, and ra.ther offensive : sometimés it bied slight-
ly. A hard mass occupied nearly the whole ante-
rior part of the right half of the chest : the sim
was hard and fixed, and small tubercles were feìt
under it fox some distanpe round the fungouspart.
The swelling and the hard state of the skin reach-
ed into and filled the axilla; it extended up to the
clavicle, as far as the middle of , the sternum, and
below the edge' of ihe pectoralis major rauscle,.
Hard tumors were felt above the claviclfiv and the,
axillary glands on the opposite side of the-body
vere enlarged. . The arm began to he oedematouSs^

gradually increased, debility carne on, and death
took place without any particular change in the lo-
cai disease, which had at na time been attendedwith.
much pain. The carbonate of iron was used both
^xtQrnally and internally : the discharge bec.amet
less offensive, a^d the bow^ls very costive uijder
its employment.
A very considerale mass of exceedingly hard
and tough substance covered the chest, reaching
as high as the clavicle, and fìlling the axilla. It
contained no cavity or celi, nor any part at ali sofì;
, in its texture. The most striking character of this
Gonsisted in its colour which was a bright yeUo^sh
green. With this there was mixed more opless red>
and a few portions nearly white. The axiUary
glands fonned a part of the general mass, from
which they could not be distinguished by their co-
hur or any other circumstance. The skin over the
swelling had its corion very much tluckened, and
this change extended beyond the middle line of
the chest. The tumor in most of its extcnt wa*
distinct from the pegtoral muscle, but had extended
through it apposite to the ulcerated portion, and
seemed to bave converted the fibres completely in-
to its own substance. The cellular tissue in both
the pectoral muscles and in the intcrcostais, as weD
p in ali parts about the region occupied by the tu--

mor, had the same remarkable green colour as the
swelKng itself. Thia colour eKtended along the
subcutaneous stratum to the opposite side of the
chest, and was observed in many points in the sub-
stance of the left pectaralis major. A very iarge
mass of substance entirely resembHng the originai
tiunor was placed above the right clavicle, and ex*
tended backwards to the spine, involving the axiU
lary artery and vein, and plexus of nerves. The
right pleura was greatly thickened, particular-
ly where it covers the diaphragm, and converted
into a tough green substance; its cavity contained
more than two quarts of a very bright lemon-co-
loured fluid. The lung was reduced to a very
small size, and its covering of pleura was t^icken-
ed ; but there was no disease in its substance.
The peritoneum lining the right side of the dia-
phragm was thickened and green ; and the mem*
brane had undergone a similar change in two or
three patches behind the abdominal muscles.
' Two hard lumps, consisting of the substance ,Qf
the gland indurated and turned green, were found
in the pancreas ; and a very considerable number of
masses of the peculiar green substance were dis*
persed through both kidneys, the intermediate
portìons of these orga^s being quite sound.
A portion of cellular substance behind one of
the vesiculae seminales was hardened, and exhibited
the green colour.

The lymjAfttic gl^nds were very extensively dis-
m^d : they w^re enlarge^ in various dqgreesj aii4
their suhstance more or lesst extensively conyarted
iutQ a bardiah homogeneaus ina$3 of the colour al*
ready described. In siome instancea this depoaitioii
occwpied the centre of the gland, and wds $ur-i
rounded by a thicker or thmner stratum of ^^
jstance resembling the naturai structure of ^q
part; in some this extemal layer had a deep red
aod bloody appearanice ; other glands were convert-
eà entirely into the green structure. The ceUular
texture surrounding the glands was loose and natu^
ral. The axillary glands, on the diseaaed side»
could not be distinguished from the originai tu-
mor, and those above the clavicie formed a large
swelling of exactly similar appearance. From
this a chain of enjiarged' glands extended to the
trachea, and along its right branch to the lung,
ali the glands of which were affected. The axil-
lary glande of the left side were very considerably
enUrged* The right ìnguinal glands were shghtly
diseased: thoee situated about the external and
internai iliac vessels, the aorta, and vena cava, as
high as the diaphragm, were greatly enlarged, and
fermed one contiuuous chaia, The largest of these
were equal in 9Ì2e to hen's eggs, and had ^e bloody
appearance externally. Two or three glands in
th^ mesentery, one on the stomach, one behind
the ^ght rectus abdominis, and several in the pos-
tQrior xnediastinum * were slightly enlarged, and
partìally ponverted into the green ^ubstance.
^6 FATAL DISBASE
The largé lymphatic tranks passing between
those abdominal glands, whioh exhibited the bloody
colour in the most remarkable degree, were dis-
tended with a reddish fluid. The thoracic duct
contained a similar fluid, and was pervious through-
eut. The tight absorbing trunk was pervious at
its termination, Neither the loft arni nor the Iqwer
lìmbs were at ali oedematous.
r The lining of the pulmonary artery arid its
branches, and of the aorta, together uvith its pri^
mary ramifications, was of a bright red colour>,
but not thickened,
" The mucous membrane of the trachea and its
branches, presented a deep red colour, and the
surface was crowded with small vessels,

• No part of the brain shewed any trace of dis-
èase ; and the right axillary nerves, which were
involved in the diseased glands and the primary
turaor, were equally free from ali morbid ap-r
pearance.
CASE II, — A woman, who had laboured for somo
tirae under a' singular afiection of the arm, grew
gradually worse, had a difficulty of breathing and
general debility, and died. The subcutaneousi
tissue of the arm, fròni the elbow upwards, wa»
converted <m thè inner side, 'and over about one
half of the limb, into a solid brawny mass of abonfj

ments into several small tuberclea. ^ >Two deep ul-
cers^ with foul surface, irregular evertéd edgea,
and uhhealthy discharge, had formed in thià dis-
eased mass. The axillary glands, and those aboye
the clàvicle^ were changed into a large tubef culated
substance, resembling, in ita hardness and very
light brown colour, the originai disease. Small
depositions of a similar kind had taken place in
the cellular substance of the biceps muscfe-; and
sevèra! small portions, hardly producing any ete-
vation of the surface, were found in the median
nerve, for about two or three inches òf its coùrse,
Very numerous* tuberei es were scattered over tbe .
sur&ce 5 . and through the substance of tbe lung« :
they possessed a whitish colour, and finn hpitìQ-
geneous texture. They were most abundant on
the surface, and varied in size from a millet sèed
to that of the end of the finger, ; There was no
appearance of suppuration in any of^them. The
bronchial glands were enlarged.
CASE III. — In a patient, who had been for some
time under medicai treatment, on account of dis-
ordered intestinal functions, and whose breathing
was affected only a few days befóre . hÌ3 deatlx, a
great number of very large and peculìar tubercles
was found in the Jungs. They were very finn, of

«f the liing had been imperfectly converted into
the turftor. In the intervals of the tubercles the
lung VFBS healthy. The foronchìal glands were con-
siderably diseased.
Fottf or fìve small tubercles were obfeeh^ed on
the heart, under its serous membrane»
A considerable lumor was ìbund ùa the upper
siirface of the diaphragm, wìth the lung adbering
to it ; and a similar one was seen under the thick
edge of the livej.
. Ève or six round and hard tubercles of different
dizes appeared in the omentum ; and many smaller
ones under the peritoneum in varìous parts òf the
abdomen* "
A white finn tubercle of the size of a nut, Was
found in one of the kidnies.
CASE rV. — In a woman,with whose history I am
entirely unacquainted, the pelvis presented a most
éestructive dìsease. The neck of the uterus was
destroyed ; the remainder of that organ, the back
of the bladder, and the front of thè rectum form^
ed the aides of a large cavity, with a rugged and

irregular surface covered by a horrìbly fetid dis-
charge. The bladder communicated with this bj
a large opening, and the larga intestine by two ul-
cerated apertures, one in the rectum, and the
other in the sigmoid flexure of tiie colon. The
firndus of the uterus had its naturai appearance ;
but the pa];t which contributed to the formation c£
tfae cavity, consisted of a white and softish mat-
ten A similar substance surrounded the rectum^
and connected it firmly to l^e sacrum ; it extend-
ed into the substance of that bone, which it had
rendered so soft that it, could be cut with a knife*
The^ inguiiud ^nds of the right side were con*
verted into a tumor of similar appearance. On the
sur&ce, and in the substance of the' liver, there
were several depositions of a white soft niatter, of
various sizes. The texture of die diseasé was very
ffitmlar in ali these parts. Maceration softened It
comsiderably, and pressure then reduced it to u

of securing it when passed.

of a noose, mach in use among packèrs; which,

cases^ where a ligatusfe is re^uired.
A single knot being first made upon one end of
the thread, tììe end so knotted, is to be brought
fotvrsofé upon the other, atid to màke a single noose
upon itself including the other, and to be drawn
tight ispòn it, dose to the first knot : the free end
of the thread is then to be passed through the ring
of the instrument, as in Rg. Ó. This end of the
thread being then held firm, and the ring pushed
forward upon the knot, the loop now formed, nlay
be readily tightened, so as completely tò* strangu-
late the diseasaì part; atid in the same manner it
may be tightened from day to day, till the part ìs
entìrely detached.

The kind of thread I prefer, is thin, strotlg lay*
cord : common packthread is so quickly rotted by
the offensive saliva^ which is afterward secreted,
added to the wannth of the mouth, and the putres-
cency of the strangulated part, that in one instance
in which I have employed it, it gave way, beforé
the tumor was completely separated : the tonsil,
however, was ^ufficiently grooved to luake it readily
included in a single ligature^ which was passed
without difficulty.
. Instead of a simple, fiat hook, I at first empio}*-
ed one with an eye, carrying the. ligature ; which,
being passed through the base of the tonsil, might
be seized with a hook, and brought forward : but
I found that the combined irritation from the punc-
ture and the thread in the fauces, was so great,
that the most determined courage was scarcely
equal to withstand it, for a sufEcient length of time,
to allow of the ligature being effectually laid hold
on, and divided: and it was from being disappoìnt*
ed in attempting to execute this part of the opera-
tion in that manner, that I was first led to the more
simple, and easy method of performing the opera-
tion, which I have now descrìbed.
A good deal of inflammation usually arises in
*
the mouth and fauces, and about the sublingual and
&ubmaxillary glands, soon after the operation ; which
ìs best soothed by small doses of laudanum and an-
timonial wine. The mouth may be frequenti/

Washed with warrn water, and the poppy fomenta-
tion employed extemally, if the pain should be
considerable. This inflammatión begins to subside
on the third day. I thìnk the tumor is generally
detached on the fourth or fifth day, and the sore
readily heals.
The ligature shòuld of course be of sufficient
length, to bang six or seven inches out of the
mouth j and it will be an usefiil precautìon to cover
the ends with a piece of adhesive plaster, which
may be fixed on any convenient part of the neck or
face, to keep them out of the way.

the 14th at noon, bis. respiration was afifected, aisd
in the evening it was loud and hoarse, and he was
long in completing each inspìration. He could
not sit stili for many moments, but walked about
the room in the greatest distress, often struggling
for breath. Unable to Uè down, he passed the en-
suing night in the same restless and agitated state,
with occasionai delirium^ On the 15th, the diffi-
culty of bis breathing was in no respect diminish-

membrane investing the epiglottis, rima glottidis
and the posterior part of the larynx, was found to
be oedematous to so great a degree, as to make it
evident that suflfocation had been prodttced by
stricture of the glottis. Tlie tumefection ceased at
the junction of the larynx and trachea. The in-
ternai mucous membrane of the larynx was red
and thickened. The traces of inflammation were
less apparent in the trachea and bronchia, the
membrane being irregularly reddened. No coagu^

gestion in the lungs ; some adhesions of the right
pleura existed, but these were not recent; the heart
was naturai, and the liquor pericardii slightly in-
creasqd. Excepting an enlarged spleen, there was
no disease of the abdominal viscera.
In this case the inflammation did not pass the
stage of congestion in the mucous membrane of
the trachea, and of sèrous effiision under the mu-
cous membrane surrounding the glottis; but in tlie
fbllowing, the inflammation went into the adhésive
stage, and closed the glottis by the efiusion of 'co-
agulable lymph.
CASE II. — A poor, but industrious and tempe^
rate man, about 60 years old, on Sunday the Slst of
March 181 1, was affected with a painful and difficuH
deglutì tion. On the fbllowing momìng, Aprii Ist,
alarmed at his inability to swallow fluid, which, on
the attempt being made, returned by his uose, he
sent for Mr. Weston who found the tonsils inflamed,
and disposed to ulcerate. A brisk purge was order-
ed. At ten o'clock, on the same evening, his respi-
ration suddenly became diffìcult, when Mr. Weston
immediately drew from his arm thirty-two ounces
of blood, which proved to be very sizy. • In the
course of an hour I attended, and observed the
character of his disease at this stage. Although
the tumefaction of the tonsils was mconsiderable,
deglutitìon was extremely painful, and very diffìcult:

respiratìon was performed with convulsive and long
continued èfForts : bis voice was nearly inaudible,
and he could only whisper. He answered my in*
quiry respectìng the seat of his suflfering, by put-
ting his finger on the superior part of the thyroid
cartilage. He feìt no pain in the chest. Ali the
muscles of respiratìon were thrown into vìdient
action, and he lay with his mouth widely opened,
pupils dilated, face pale and sunken, skin covered
with a clammy sweat, and his pulso at 133, and
smaU. His powers were prostrate, and general
bleeding could not be repeated* The anterior part
of the throat was covered with leeches, but the dis-
case never paused. At midnight, the op'eratìon of
bronchotomy seemed to be the only resource ; and
soon after one o'qlock^ I decided on its employment.
About two o'clock, Mr. Astley Cooper attended,
and as suffocatìon was instandy impending, the
operatìon was immedifitely performed, by dividing,
laterally, the ligament which connects the thyroid
with the cricoid cartilage*. The dyspnoea was '

muscle that could be brought into action to assist respiratìon was
employed. He was seized with sore throat yesterday, and at ten

There was some accumulation of mucus in the

more fluid than is naturai to them. The abdom*

The anterior part of the pharynx was indeed
the sèat of the inflammation ; but that portion of
the membrane being also common to the larynx, it
may, in a practical sense, be uséfiil to ternv the
disease laryngea^ because it proves fatai by con-
stricting or actually closing the glottis, and consti-
tutes precisely that case which, in its ultimate de-
gree, imperiously demands the operation of bron-

A CASE

A NiESTHES I A,

PHYSICIAN TO THE LONDON HOSPITAL.

i HE foUowing case exhibits an example of the
loss of sensation in the upper and Ipwer extremities,
independent of paralySs; and as some pf the parti-
culars are curious, and the occurrence of such a
complaint is exceedingly rare, I have drawn up am
account of ìt for the use of the Society.
I. S. aged 58 years, a native of Scotland, residèd
for many years in Jamaica as a pian ter; and with
the exception of being now and then bilious (to use
his own terni) he enjoyed, during the whole of this
period, very good health. About three years ago,
after being much heated and fatigued in his ai^ttend-
ance, as one of the Grand Jury in Kingston, in
CASE ÒF AN^STHESIA, 9l
very sultry weather, he went to bed with the wìn-
dow open, On awaking in the morning, he found
liis feet and ancles perfectly numb, but without
any sensation \)f pain, and without the muscular
power beiijg at ali affected. Soon afterwards, he
felt a numbness, with a tingKng pain in bis little
finger, such as occurs in a part which is said to be
asleep ; and, by degrees, finger after finger became
affected, until the whole of both hands was in a
considerable degree insensible. He never had any
pain or giddiness in the head, nor was he ever af-
fected with the dry colie, which so often gives rise
to paralytic affections in the West Indies.
A physician of eminence in Jamaica confidently
assured him, that bis complaints originated from
scurvy in some lurking forin or other; but it does
Dot a;ppear that Mr. S. ever had the least appearance
of cuticular afFection, till about 1 2 months after the
occurrence of the numbness, when some red pim-
ples shewed themselves in bis legs, on bis lying
down on the ground, after being much heated by
walking up a steep hilL ^
He arrived in this country on the 20th of July
last; and from the time of my first seeing him,
(which was on the 25th of Ofltober) till now, he
had been as nearly as possibIe\in the same state,
cxcept that bis appetite and digestive powers,
which were then a good deal affected, bave been
for some time past much improved.
98 HISTORT OF A CASE
The foUowing are the prìncipal circumstances
i^hich I bave had occasion to observe relative to
this case.
The hands, up to the wrists, and the feety half
tray up the leg, are perfectìy insensible to any spe-
cies of injury, as cutting, pinching, scratching, or
burning. The insensibility, however, does not sud-
denly terminate ; but it exists to a certain degree,
nearly up to the elbow, and for some distance above
the knee. He accidentally put one of his feet,
some time ago, into boiling water, but was no
otherwdse aware of the high temperature, than by
finding the whole surface a complete blister on re-
moving it. Nq species of injury to a vesicated part,
of either hands or feet, is felt by him. The extre-
nfùties are insensible to electrical sparks takea in
every variety of mode. The cubital nerve where
it passes the elbow communicates the sensation prò*
duced by pressure or a blow only half-way down
the fore-arm*. He perspires much in the left side,
just above the hip, but nowhere else« He is gene-
rally rather chilly, and the extremities are coW,
* I bave remarked in some cases of paralysis from Colica Pic-
tOTuro, that this nerve has its sensibìlity very mach diminished;
and in the case of a brìcklayer^ in whom there was a total loss of
power, and in a considerfd)le degree of sensation in both of the
fore-arms and hands, fr|(^ sudden exposure to cold, after working
in a very hot furnace, the cubital nerve was totally insensible to
àny degree of pressure or force applied to it. It is probaUe that
a similar insensibility might have been fonnd to exist in other
nerves, had they been accewible.
OF AN^STHESIA. 93
except when he is in a comfortable room ; and in
this case they are crf the usuai temperature of thci
body. The thermometer however rises to 101^ in
the mouth. The hands are of somewhat a purple
liue. If he wishes to ascertain the temperature of
any body, he is under the necessity of putting it to
his fece ór neck, or the upper part of his arm, His
skin seems to be more than usually sensible to thè
efiects of beat. On putting his band, at the desire
€^ a friend, into a paìl of hot grains, which his
fìiefid assured him were not too hot, and to con-
vince him of this, previously thrust his band and
arm into it, there was a very extensive vesication
produced. His hands are never free from blisters,
wtócb he gets by inadvertently putting them too
m
near the fire ; and he has met with* several severe
bums, without being aware of it. No degree of
pressure is felt by him ; but a blow produces a
sHght degree of tingKng. He has a general uneasy
sensation in the extremities, which warmth rather
relieves. His skin, in general, heals very readily,
after being bumt or scalded in the most severe way j
and there is no fèver, nor is there, as far as he has
been able to determine, any increased beat or
throbbing during the process of healing. This
seems to be also the case with some other parts of
his body which are not altogether insensible; fora
little tìme ago, he got bumt in the front of the pa-
telkt, and though there was a consid^erable slough
separated in consequence, he sufFei^d no pain, and
little inconvenience during the cure.
3
9é ilISTORY ÒF A CA8É
If the heat to whìch the insensible parts are ex*
posed is moderate, vesicatìon is not immedìately
produced. The part becomes red, and in a few
tninutes, but sometimes not till the lapse of an hour
or two, is bKstered, That a smaller than ordinary
temperature produces vesication in this individuai,
seems to be ascertained by the circumstance, that
cxposure to the heat of a common fire gave rise to
a blister in the knee, which was foUowed by the
slough abovementioned, though the clothes which
còvered the part, were not at ali injured. Immer-
sion in water at 120"* produces no change in the
affected parts; but exposure to the same 4:empera-
ture at a common fire, speedily blisters, That de-
gree of heat, is, as far as I can judge by myself,
about the utmost which can be long borne by the
hand, in ordinary circumstances, without pain*
Cold water and warm water of every tempera-^
ture invariably appear lukewarm to him. Water at
the freezing point produces no degree of sensation
whatever; but when his hand is kept in it for some
time, he feels a slight coldness at the end of the
thumb. After his hand has been immersed in wa-
ter of the common temperature, and was introduced
into water of SS'', he had some sensation of warmth.
The cold produced by means of a mixture of snow
or ice, and salt, communicates no sensation except
a slight chiUiness in the thumb, and when this
freezing mixture foUows the use of water of the
common temperature, it produces a slight degree
OP ANi&STHESIAé 93
of warmth. A soKd body produces no sensatjion,
whatever its temperature may be* , .
The power of motion exists in the muscles of
both hands and feet. With the former he can
grasp pretty firmly ; but in holding any thing he is
apt to drop it, if his attentìon is at ali called away.
There has been of late a slight loss of substance in
the hands.
He can lift a chair, but cannot raise himself from
the ground, by taking hold of any thing placed
àbove him. The susceptibility of impression, ge-
nerally, as well as the muscular power, seem to be
in this individuai in some degree diminished.
/
The functions are naturai, and the pulse regular
^nd moderate *.
In the treatment of these symptoms, no advan-
tage has been derived from any pian which I bave
myself adopted, or which has been employed by
others. The warm bath, electricity, galvanism, to-
nics, the rhiis toxicodendron, and mercury, given
both witli a view to its action on the bowels, and
the system at large, bave been equally unavailing;
though it must be owned, that the patient has ne-
ver shewn a sufficient degree of perseverance, in
the prosecution of any means which bave been
adopted for his relief.

the distance of an inch and quarter from the middle
of the dorsura of the metacarpal bone. Il touched
the bonejj and must bave passed thrbugli the mass
of short flexors of the thumb. Not the least de-
gree of pain, or even of sensation, was produced by
this puncture. The part was desired to be poul-
ticed, and the wound appears to bave healed by the
first intention ; for the poultice was considered by
the patient to be quite unnecessary after the 2nd

I have met with two instances very iiearly re-
sembling that which I have now laid béfore the
Society*. The first occurs in the American Me-
dicai Repoi^tory, and is communicated in a letter
from Dr. Samuel Brown, of Le^^ington in Ken-
tucky, to Dr. Miller, one of the editors. It is
dated June so, 1799, and is as follo wst.
" Mrs. M'L. of Baridstown, in Kentucky, aged
about 40 years, has been deprived for more than
two years, of the power òf sensatiòn in her hands
and feet. She is quite insensible of the efFects of
cutting ihstruments, or of buming coals applied to
them. In one instance, when she was employed
in s^iaping a pièce of woòd with a knife, she in-
cautiously turned her eyes on some other object,
and cut off the end of the thumb of héìr left band,
without perceiving the smallest sense of pain.
ISie cannot, from her sensations, discover the least
difference between a hot and a cold iron, and has
frequently burnt the skin and flèsh to a considera-
ble depth, by mìstaking the one for the other.
These wounds and burns heal without any uncòm-
mon difficulty. Notwithstanding this total loss of
sensibility, she retains the power of motion in foli
perfection, and pursues her domestic employments

During his work, the subject of this case happened
to break the bones of his fóre-arm, at about a third
of their length from the wrist. As he only felt a
crash (craquement) he thought he had broken the
shovel which he held in his band ; but it was sound,
and he could only discover his accident by being.
unable to continue his work. The following day»
the arm, at the fractured part, was pufied up ;
the temperature of the fore-arm and band was in-
creased, but the patient experienced no degree of
pain, even during the extension necessary to re*
duce the fracture*. In this case, it is clear, that
the muscles of the affected arm were equally in-
sensible with those of L S. And it is probable
that this was also the case with the person men-

ReadApiilU, 1812.
JyllSS D- 5 aged 14, for several days felt
pain in the head and back, which induced her, on
the 26th of February, to apply for medicai assist-
ànce. Blisters were applied behind the ears, and
opening medicìnes were ordered, which operated
the following day, and relieved the pain in the head ;
but the pain in the back grew mach worse, and
was aggravated and accompanied with a tendency
to sickness, on sitting up* On the Srd of March
the pain in the back ìncreased much, and on the
following day ber mother thought she discovered
THE THfiCA VERTEBRALIS. 103
a little projection of the spinous processes of the
lumbar^ vertebrae, in consequence of which I was
desired to see her. I could not discover any thing
in the appearance of the back that was nòt naturai,
nor was any particular pain excited by pressure.
The efFort to sit up distressed her much j but her
countenance was clear and healthy. The tongué
was rather white: she had a moderate, regular pulse
at 1 20, Under these circumstances the pain did
not excite any particular alarm in my mind : I di-
rected some leeches to bé applied as nearly as pos-
sible to the seat of the pain, and afierwards an opi*
ate lotion : she was also ordered to take three grains
of antimonial powder, with a saline draught every
àx hours, and I left her in foli expectation of find-
ing her relieved on the morrow, especially as, on
strict enquiry, she could recollect no exertion or
other vìolence by which the symptoms could bave
been produced.
On the foUowing morning, to my great surprise,
I was informed that, on the evening after I had
seen her, she complained of a sudden and violent
increase of the pain, and immediately went into
convulsions, in which she continùedbetweenfiveand
six hours and then expired. On the 6th of March I
examined the body in the presence of Mr. Johnston
of Mortimer Street, who had attended her from
nearly the commencement. There was not the
leasfc appearance of disease in the brain or in any
of the thoracic or abdominal viscera. The appear-
104 EXTRAVASATION WItHiN tBÈ
alice of the spine wad also perfectly naturai. I
therefore proceeded io cut away the bodies of the
]umbar vertebrae in order to expose the cavity of
the spinai canal, dose to the seat of the pain. 1
found it filled with extravasated blood, which froni
its florid colour must certairily haVe beéft arterìal,
and which covered the whole of the caudà equina.
The cavity appeated to be filled much higher up ;
but I did not prosecute the dissection as it did not
appear to me of much consequence to ascertain the
exact limits of the extravasation, and the violence
that must bave beén committed in openitìg the ca-
vity Éirther, would bave rendered it difficult, if
not impoasible, to teli precisely from v?tlat vessel the
blood had issued. The originai seat of the pain
would naturally lead me to suppose that the rupture
must bave taken place near the commenCement of
the cauda equina, and it is prob&ble the efiusion
of blood stopped within that part of the cavity in-
closed by the dorsal vertebra?, as there was no ap-
pearance of it at the foramen magnum occipitale
when the brain was examined.
The blood, thòiìgh tìorid, Was notali òf an equal
tint, it was very imperfectly coagulated; itis there-
fore probable that the vessel first gave way at the
commencement of the illness, and again to a much
greater extetit at the time the convulsions carne on.
I apprehend cases exactly of thi^ descriptìon bave
not been very commonly seen ; but that similar
ìnischief should fiequently occur, in consequence of
tHÉCA VERTEBRALIS^ lOj
VÌoleht straìns, is naturally to be expected : and I
believe the foundation of carióus spine, which isof-
ten laid by sudi accidénts, is not unfréquently at-
tendedby some such mischief, which, as it raay take
place in variots degrees, would account for the great
disproportion óne Sées in examining a multitude of
Cases of this sort, between the degree of curvature
in the spine, and diminution of power in the lower
extremities^
A child of là months old, who had just reco-
vered from thè operation for hair Hp, was carried
cut by the nurse. On its return home, it seemed
in mach pam, and appeared to bave lost the use of
its lower extremitieS: it died in three days. Onopett-
ing the body I found the spinai canal full of a bloody
serum, which, I have no doubt, was occasioned by
slight extravasatìon from a strain and subsequent
Inflammatory effusion. And how destructive such
extravasatìon, and inflammation combined raay be
to the structure and office of the nerves, was illus-
tratedby the case of a miller, who suddenly lost the

DlABEigplS INSIPIDUS, when existing as an
idiopathìc disease, is of such rare occurrence, that
I presume! the following case, which appears to me
to be entitled to this appellation, will not be un-
interesting to the Society*.
* The rariiy of the disease is very deciàedly proved by this
circuiDstance, that since the tìme of Willis, who first pointed pu^
the sweetness of the urine^ scarcely any distinetly detailed case
of diabetes insipidus is on record. Cullen, with that tlegree of
scepticism which is so characteristic of a philosophic mind, he-
sitates whether he should admit its existence^ yet he informs us
that he had seen one case in which the urine was not saccharine''^.
The two cases related in Dr. Rollo's work, in which a large quan*^
tity of watery urine was evacuated, were consequent to a locai
injury of the kidney, and therefore do not belong to this classf.
No^ do I regard the case in Dr. Duncan's annals, as entitled to
the appellation of diabetes ; it was attended with profuse perspi-
ration, and it may be inferred from the remarks, that the ap-

was under my care for a violent and long continued
attack of menorrhagia, by which she was much re-
duced in lier strength, but which was finally re-
moved, and was fbUowed by a total > cessation of
the menstrual dìscharge. She considered herself
well, although a great degree of weakness re-
mained ; she complained of being much fatigued
- after using the least èxercise, and remarked that
although her appetite was good, yet that her food
never appeared to give ber any sypport. The ge-
neral weakness and the peculiar /state of the sto-
mach increased upon her, and at length becam$
so marked, that I was again called upon to visit
her. The symptoms which she described, imme-

The average quantity of urine passed by this
patient in 24 hours, was 5 quarts; an ounce
measure ' of it, which I examined, weighed 492
grains : therefore the whóle quantity evacuated
would be ^xactly I05;lb3. Troy. It was pale and
nearly transparent ; it had a faint odour ; it slight-
ly reddened litmus ; and the specimen upon which
the foUowing experiments wej^e made, had the
specific gravity of 1,034. The residuiim, which
was left by slow evaporation, in its physical proper-
ties did not seem to differ from the extract of
healthy urine. It appeated, by a simple calcala-»
tion, that she was discharging between nine and
ten ounces of s«Jid water in th%24 hours ; this
may be estimated at about 8^ ounces more than.

The constituetits of the urine were then more
particularly examined. A quantity of the extract
wàs digested in alcohol, and when ali was removed

fluid was evaporated. The part left by the evapo-
ration of the alcohol, was to the part which the
alcohol did not dissolve in the proportion of 17 to 4j
* The weight of the entire urine in the healthy state, and the
proportion of the sohd contents to the watery part, can only he
obtained by an average estimate, and that subject to great uncer-
tainty, in consequence of the numerous circumstances wiiich
produce a variation both in the quantity and the quality of this
excretion. Haller, witb his accustomed diiigence and accum'cy,
Las coUected a great body of authorities witb respect to the quan-
tity of the urine, froni which he fixes it at 49 ounces daily. But
in forming this estimate, he hàs not exercised that judicious dis-
crimination for which he is'generally so conspicuous ; after stat-
ing the diflèrent quantitìes that are given by diffèrent wiiters»
(which vary from 28 to.64 ounces) he takes the general averagCi
regarding the number more than the weight of bis authorities'^.
The observations which appear to me by much the most accurate,
are those of Rye, who fixes the quantity at 40 ounces f. The
proportions which bave been assigned for the water, and the soUd
contents of the urine are as various as those rcspecting the entire
quantity. Haller has coUected diffèrent estiinates, which make

and as the former of these consisted principally
of urea, it appeared to be in this case ratìaer
more than four times the weight of the saline sub-
stances. By refei^iflig to the quantities mentioned
above, it will be found that this patient was dis-
charging daily about 7^ ounces of urea, and nearly
2 of different saline substances. I could not dis-
cover any portion of sugar in the urea, nor did I
observe any thing peculiar in the nature of the
salts.
With respect to the proportion which the animai
matter in the urine bears tò its saline ingredients,
the statements of different writers are completely
at variance- MM. Fourcroy and Vauquelin say,
that the sàlts form . only »% of the weight of the
extract*, while Mr. Cruickshanks informs us, that
they amount f o about ^ of it, or, more exactly,
that they are to each other as 315 to 220t. It is
not imppssible, or even iraprobable, that the urine
may diiSfer from itself so much in different states
of the body, as that both these aCcounts may be
correct, as applying to extreme cases ; but grant-
ing this to be the case, they stili give us no idea of
the average condition of the fluid. The results of
two experiments, which I made with a good deal
of attention, were that, in the first, the salts were
tothe urea as 13 to .69, and in the 2d, as 24 to
79 ; the average of these is as 1 to 4, a proportion
which is not very far from the medium between

the estìiiiates of the French chemists and Mr.
Cruickshanks. Supposing that the whole of the
soUd contents iixJthe healthy state, amount to 600.
grs. the urea will compose 450, and the salts 150
grs. ; my patient was therefore discharging daily
abov^ 6 ouuces of urea, and above 1^ of sisdts
more than the naturai quantity. Such a waste of
the system, may point out to us the final cause of
tlie ìncreased appetite for food, and the excessive
thirst, which form some of the raost characteristic
symptoms of diabetes.
In endeavourìng to detect the presence of sugar
in this urine, I employed the action of nitric acid,
and concluded that there was no sugar, because
no oxalic acid was formed. In order to try how
far this method of reasoning was correct, a quan*-
tity of pure urea, prepared from healthy urine,
had y\f of its weight of sugar added to it, and
upon it was poured 6 times its weight of a mixture
of equal parts of nitric acid and water, and heat
was then applìed. When it had been boiled to the
consistehce of a thick syrup, and was beginnìng
to assume a^tlark colour, showing that the nitriq
acid was separated, it was removed from the lump;
in a few hours crystals w^ere formed, which, afler
being dissolvéd in water and reorystalliised, seemed
to consist of pure oxalic acid.

With respect to the treatment which was adopt^

tiiarks. As tìie urine was not saccharìne, animai
diet was not prescribed, and those remedies only
e^fij^oyed which wére snpposed to bave tìie power
of strengthening the digestive organs, and repró-
ducing a healthy state of the skin. For the for-
mer purposé the preparations of iron were chiefly
relied on, and for the latter the warm bath ; but I
suspect tìiat the morbid symptoms were so far con-
aected, thatwhatever tended to relieve the one,
was likewise beneficiai to the otìier. The result
was completely successfìilj the constitutional a£
fections disappeared, the urine was reduced to the
nafìiral standard, and the sur&ce regained its
h^thy action. The patient has remained well
ibr above li months.
To the case that has been now detailed, I con-
ceive the appellation of diabetes is strictly appli-
cable ; it possesses the three pathognomonic symp-
toms of the disease, the increased appetite for
fbod, the suppression of the cutaneous dischaiige,
and especially, the evacuation from the urinary
organs of a larger quantity than ordinary of ani-
mal matter. This latter circumstance is essen-
tially diiièrentfrom the mere increase in the quantity
of water, a morbid state which has been often con-
fouiided with diabetes, but from which I regard it
as totally dissimilar. The quantity of matter dis-
charged from the urinary organs, when the disease
is fiilly formed, or exists in an aggravated state,
is so considerable, as to increase the specific gra-
voL. ni. I
114 OBSERVATIONS ON
vity of the fluid, iiotwithstanding the great increase
in its quantity*. In thìs case it appeared, that
the specimen upon which the experiments were
made, which was obtained after the patìent had
been for some time without evacuating the bladder,
had its specific gravìty considerably increased, al-
though the average specific gravity of the urine
passed during the 24 hours, was not above the or-
dinary standard. Although cases of diabetes in-
sipidus bave been so seldom noticed, yet I am dis-
posed to believe, that it is a more fi'equent occur-
rence than is generally imagined. It is seldom
that the attention is directed with so much mi-
nuteness to the urinary discharge, as to enable the
practitioner to ascertain the nature of its ingre-
dients, and should the increase of its quantity be
noticed, it is thought to be accounted for, by the
increased quantity of fluids that are employed to
allay the thirst.
We are perhaps not able to decide with perfect
certainty, whether this disease be the commence-
ment of the diabetes mellitus, or has a tendency
to terminate in this state. I conceive, however,
that the opinion is in itself probable, and it ap^
pears to be strongly confirmed by a case which
occurred to Dr. Lewin, of Liverpool, the parti-
culars of which he communicated to me, and upon
which, at bis request, I madé some experiments.

I DiABEfES INSIPIDUS. 115
The patient was a hùddle aged female, and had a
variety of complaints ìndicating general debility,
and a decayed state of the digestive organs, which
led him to suspect the existence of diabetes ; and
upon inquiry^ he found that the urine was rather
more copious than naturai» He sent me a quan-*
tity for exatnination, the general results of which
were as follows. It was somewhat opake, and of
rather a browner colour than naturai ; by stand-
ing, it deposited a sediment, and then became
more transparent. The difFerent re-agents prò*
duced nearly the usuftl effects, except that the
scaly crystals, formed by adding nitric acid to the
urea, were less distinctly visible than ordinary.^ I
thought the odour of the urea was le^s urinous
than naturai, but I was unable td procure from it
any oxalic acid by heating it with nitric acid.
Dr. Lewin afterwards sent me a second speci-
men of urine, discharged by the same patient, the
properties of which were, in sever^l respects, dif-
ierent from what I had before examined. It wa3
more opake, and deposited a greater quantity of
sediment, its odour was sourish, and scarcely urj-
nous* The extract produced by a slow evapora-
tion, instead of being granulated, was of the con-
sistence of a thick syrup, and when nitric acid
was added, the scaly crystals were only imper-
fectly formed, and mixed with a quantity of un-
crystallized matter. This half crystallized mass
had a fresh quantity of nitric acid paured upon it,

and the beat of a lamp applied ; a brisk efferves*
cence was excited, and a vapor disengaged, which
had the odour of nitro-muriatic acid. The prò-
cess was continued until the fluid was nearly eva-
porated, and a mass was obtained, which, when
cold, resembied candied honey. This was dis-
solved in water and partly evaporated, and in 24
hòurs some fine spicular crystals were formed,
which produced a copious precipitate with lime
water, and exhibited every property of oxalic acid.
The result of this exaraination appeared to me so
important, that I was desirous ot having it con-
firmed by Dr. Henry, and I accordingly sent him
a quantity of the solution of the honey-like sub-
stance. He replies to me as foUows : " The small-
er phial unquestionably contains oxalic acid, as I
determined not merely by the fact of a precipita-
tion, but by examining the precipitate, which, in
ali its characters, answered to oxalate of lime.*'
To Dr. Lewin's sagacity in detecting the nature
of the disease in this early stage, we may consider
ourselves as indebted for the important fact, that
a small quantity of sugar can exist in mine along
with a largè quantity of urea*. The case is almost
. * The fact bere statcd is preciaely the cscmverse of that ad-
v.anced by Dr. Henry ; he discovered that a small quantity of
wrea can exist in urine with a large quantity of sugar, wliile I
bave detected a small quantity of sugar united to a large quantity
òf urea. These facts may bc considered as mutually illustrating
each otber, and become more interesting by their contrast.

eqiially decisive in favour of the conversioni of the
insipida into the saccharine diabetes, and renders
ìt probable that the two states alternate with each
other, until, as the constitution becomes more and
more impaired, the saccharine state of the urine
predominates.
I bave referred above to that morbid state of the
urinary discharge, in which a large quantity of
fluid is evacuated, but in which the animai matter
exists in less proportion than naturai. Such cases
bave generally been considered as diabetìc ; but I
am disposed to doubt the propriety of the denomi-
nation, and to regard them either as the sequel of
proper diabetes, or afièctions of a totally difterent
nature, perhaps orìginating in a disease of the kid-
ney*. A remarkable instance of a large discharge
of watery urine, lately occurred to Dr. M'Cartney,
one of the physicians to the Liverpool Infirmary,
who sent me some of the fluid for examination.
Upon pouring it from the bottle in which it wa«
contained, it seemed so very unlike urine, that I
coQcluded there had been some mistake respecting
it, and requésted that a fresh specimen might be
procured. It appeared, howeverj that my suspi-
cion was withojj^ foundation, for I received a se-
cond quantity,^ ip^hich exhibited exactly the same
properties with the first.

It was nearly without colour and smeli, slightly
opake, neìthe;r acid nor alkalìne, and had a spe-
cific gravity not much superior to that of water*.
At the time when the patìent was discharging 4f^
quarts in the 24 hours, the sólid extract amounted
to no more than ihs part of the weight of the fluid.
The action of nitric acid upon the extract pro-
duced a kind of spongy mass, in which the scaly
crystals were scarcely, if at ali, perceptìble, nor
was ^ny oxalic acid formed when an additional
quantity of nitric acid was heated with it. The
oxymuriate of mercury threw down a slight floccu-
lent precipitate, which was rendered more dense
by boiling, but no effect was produced by beat
alone, por by the addìtion of tan. The other re-
agents, commonly employed to detect the salts pf
the urine, threw down precipitatesi which seemed
to be in the usuai proportion to each other, but in
smaller quantity than ordinary. Heated alcohol
dissolved about 3- of the extract j the alcohol, upon
being evaporated, left a brown substance, which
in its extérnal appearance bore a resemblance to
the urea, but which was found to diifer from it in
b^ing reducible by a moderate beat to a dry state^
when it assumed a kind of crystalline appearance.

crystals, of nearly a white colour. That part of*
the extract, which was not soluble in alcohol, was
chiefly dissplved by water ; but a portion was left,
which when separated and dried, had the appear»-
ance of a fine black carbonaceous powder : it com-
posed about ^ of the mass which was not soluble in
alcohoL The composition of the extract would
therefore be nearly as foUows : 63 parts of a saline
mass, which seemed to consist of the usuai muria-p
tic and phosphoric salts, 26 parts of an animai
matter, and 1 1 parts of the carbonaceous powder.
The urine soon acquired a nauseous smeli, became
slightly alkaline^ and deposited a small quantity of
a flaky sediment j but it afterwards remained for

I relate this case rather as exhibiting a singular
and curìous state of the urìnary discharge, tlian as
directly leading to any physiological conclusions,
One circumstance, however,is worthy of notice, that
in this, as well as in the case of watery urine which
I formerly published, the deficiency of the salts is
not so considerable as of the animai matter. In this
respect the urine seems to be analogous to the al-
bmmnous fiuids of the body : for in the elaborate

The following train of facts, although not im-
medìately connected with the subject q£ the abov«
paper, I consider not undeservìng the notice of the
Society, as tending to throw some light upon the na-
ture of the extract procured from the urine of dia^
betes mellitus*
About eight years ago, I procured some diabetic
extract from urine, which was so highly saccharìne^
that by mere evaporation at a low temperature,
the whole was converted into a dry substance, of
a granulated and half crystallized texture, which
in its appearance very nearly resembled fine brown
sugar. It retnained for a long time without un-
dergoing any alterations ; but having been placed
in a damp room durìng the last winter, upon ex-
amining it some weeks ago, I found its appearance
entirely changed* The paper containing it, which
consisted of several foids, was covered with a thick
coating of mould, not uniike the mouid of cheese.
The substance that remained within the paper- was
much diminished in bulk, and had lost ali appear-
ance of sug^r i it was of a viscid consistence, and
looked like balf meked glue ; it was of à brown
Golour and musty smelL It seemed io experìence
no f^rther ehange by exposure to the atmosphere.
Water, when boiled with it, was tinged of a light
brown colour ; the substance seemed tó be rendered
whiter, but it did npt appear to be soluble i^ thì$
fluid. Boiling alcohol rendered the substance
harder and wjiiter, but no solution was efiected.
Caustic potash, when assisted by beat, dissolved it
in moderate quantity; the solution was brown,
soapy in its consistence, and frothed much when
boiled ; sulphurìc acid threw down a white flaky
precipitate from the solution. Nitric acid, when
diluted with an equal bulk of water, soon began
to act upon this substance ; when heated to ebulli-
tion the substance was dissolved, with the disen-
gagement, first of nitric vapor, afterwards of ni-
trous gas. The colour of the acid was much deep-
ened, and its consistence was thickened; as it
cooled, some flakes separated that resembled a •
concrete oil : the acid had acquired that peculìar
odour which attends the action of nitric acid upon
the muscular fibre. When potash was added in
excess, the nitric solution acquired a deep orange
colour, a grey precipitate was thrown down, and
the fluid was left nearly transparent. When am-
monia was added to the nitric solution, there was
a very copious emission of white fumes, and the
same ehange of colour as with potash.
These experìments were sufficient to show, that
122 OBSEEVATIONS ON DIABETES INSIPIDUS*
the saccharine extract had been converted into &
substance very nearly resembling coagulated albu-.
men. It is probable that the albumen must bave
existed in the first instance, mixed with the sac-
charine matter; but in what way the saccharine
matter was decomposed, and the albumen coagu*
lated, are points that I confess myself not able to
detennine.

account of the difficulty of the case. Whcn I ar-

arose, from the heads of two chìldren being in the

a fall, or some other accident, which threw her in*
to premature labour. I was informed, that upon
this occasion, her delivery was effected without
difficulty, and thè child was bom, with so much of
life, as to cry faintly once or twice, before it ex-
pired.
In November, 1 809, she fell into labour of her
second child, at the full period of gestation. It
was now for the first time discovered, that ber pel-
vis was very much defòrmed, and that there was
no possibility of the delivery beìng effected, with-
out extraordinary assistance. The surgeon-accou-
cheur in attendance therefore requested, that there
should he a consultation upon the measures to be
adopted; and two physician-accoucheurs being
joined in consultation with him, it was judged ab-
solutely necessary, to bave immediate resource to
the perforator. Accordingly the contents of the
cranium were evacuated, but it was not till after a
V. very long, hard labour, that the child could be
brought into the world.
In her third pregnancy,^ she consulted with Dr.
Denman, and myself, respecting the expediency
of having premature labour brought on. As we
both agreed in opinion, that this would give the
only chance of her being delivered of a living
child, it was detenriined to perform the operation»

and a fortnight of her pregnancy, and being in good

health, I punctured the membranes, in the even-
ing of Tuesday, Febraary 13, 1811. The pains of
labour began, in the night of Thursday the 15th,
and I was sent for the next moming, when I had
the mortification of finding the child^s arm in the
vagina.
Having apprì^ed Dr. Denman of this untoward
position of the child, he carne immediately to see
the patient, and to afford his advice and assistance.
The OS uteri appearìng to be dilateable, I cautious-
ly endeavoured to introduce my band, for the pur-
pose of tuming the child; but the irritation this
produced, threw the uterus into such strong action,
that we thought it more prudent to desist, and to
allow some more hours to pass over, before another
attempt should be made. We expected, that, in
the meafi time, the parts would become more dilat-
ed, and as the child was small, that the feet would
be forced by the pains, nearer to the os uteri, by
which the operation of turning would be much &-
cilitated.
At 8 o'clock in the evening, I made another at-
tempt to tum the child, and accomplished it, with-
out more difficulty than usually occurs in tuming,
in a contracted uterus, after the liquor amnii has
been so many hours evacuated.
The feet, being brought into the vagina, were
soon expelled by a pain, and almost immediately

afterwards the hips protruded through the os e^t-
temum« At thìs time^ the pulsation in the ftmis was
strong, and the child vigorous; but when the head
became wedged in the narrow part of the pelvis,
the navel string was so much compressed, as soon
to occasion the child's death. It was nearly half
an hour before the head could be brought ìnto the
world, though the action of the uterus continued
very strong^ at ìntervals, during the whole time.
Immediately after delivery, the mother was seized
with a very violent shivering fit, of more than an
hour's duration. This was fbllowed by so great a^
degree of fever and delirium, as to create consider-
able alarm for her safety; and I was, in conse-
quence, induced to order for her, an active cathar-
tic, preceded by a dose of calomel, in a very few
hours after deUvery. From these remedies, a co-
pìous evacuation of very offensive dark coloured
foeces was procured, which gave her great relief. In-
deed it is probable, that the early exhibition of tliese
purgatives saved her life, for her fever ran very
high, and she continued in a very dangerous state,
fbr seven or eight days. At length however she
perfectly recovered.
Mrs. Jenkins, 22 years of age, in labour of her
first child, was attended by a veiTy experìenced ikiid-
wife. Her labour began on the 1 5th of November,

veiy strong and frequenta but the child's head
made little progress, in descending into the pelvì^é
My assistance was therefore requested on the 1 7th
in the evening* This woman had been extremely
ricketty when a child, and the pelvìs was in conse-
quence very much deformèd.
I believed it necessary to bave recourse to the
perforator without delay, and having removed one^
parìetal bone, I left ber under the care of the mid-
wife, that the pains might force the head, thus di*
minished, lower into the pelvis. At the end of
five or six hQurs, finding that no apparent progress
was made in the labour, I endeavoured to extract
the head, by the help of the blunt hook, but could %
net finish the delivery without great difficulty.
At the beginning of the présent year (1812), I
leamt, that this poor woman was again pregnant \
and being convinced by anexamìnation, to which, at
my rèquest, she iiow again submitted, that it would
be impossible to deliver ber of a living child at the
full period of utero-gestation, I determined with
her ready consent on performing the operation for
inducing premature labour. Accordingly on Wed-
nesday, March 4, 1812, 1 punctured the membranes
in the evening, giving her àfterwards a dose of tinct.

been irni^h questioned since this time, does not
appear to have beèn doubted by these experienced
practitiónefis. For the proposai was, that labour
shouid be brought on at seven months, in Ijiose
casea onlyj where it had been previously ascertaìn'-
ed, that the pelvìs was too much contracted, to al*
lòw a foli sìzed foetus to pass undiminished» By
Ibis operation, therefore, it was proposed to give a
chance to the mother of bearing a living child at
seven months, which must of necessity be sacrificed
to her safety at nine months. The idea was pro*-
bably suggested, by the success which had occa^^
sionally attended the practicej recommended by
Guillemeau and others, of rupturing the mem-
branes at an early perìod, in cases of profuse ute-
rine haemorrhage, during pregnancy.
Objections to the morality of this practìce^^ are
much more frequent in the writings df fbreign
practitioners of midwiféry, than in those of this
country. Sue» Baudelocque, and Gardieu, ali ac*

practice is contrary to the laws of iiàture, but be-

14Ù CASES OF LABOUR
hdng on premature labour, six weeks befbre tìi«
ifìill time, and the patient was delivered of a liv»
ing child, and ultimately recovered.
Men in extensive practice in midwifery must bc
tware, tìiat the state ù£ irritabìlity of stomach bere
described, occasianally takes place at ali stagès é£
pregnaney ; that however severe it, may be, the
complaint frequéntly ceases before the termination
of the prégnancy, and that very small quantitìes
of simple diet, containìng but little riourishment,
and nothing stimulating, will, under such circum-
stances, support the mother for an inconceivably
long space of time, without destroying, or injuring
the foetus. It may likewise be remarked, that
this state of irritabìlity of stomàch is generally
connected with more or less of inflammatory acti-
on, either in that viscus, or in some of the nei^-»
bouring parts ; to relieve which, bleeding is per-
haps, of ali others, the most appropriate rémedy :
while cordials, and aromatics serve but to aggra-
vate the complaint. Now as the patient in ques-
4ion took remedies .of the latter class, while the
former appears to bave been neglected, I think
this case cannot be held up, as a proof of the ne*
^essily of resorting to this expedient.
Writers of the best authorìty bave remarked,
&at in acute and dangerous diseases, thè spenta-
neous occurrence of abortion or premature laboùr

strong reason against exciting premature labourby
art^ during the continuance of such dìseases. And
though the practice of ìnducing premature laboui:
in cases of distorted pelvis has rarely been attended
with alarming consequences^ yet I apprehend that
I bave mentioned enough to shew, that there is no
absolute freedom from hazard, even when the wo-
man's health may be called good at the time of the
operatlon, and how much the degree of hazard must
be increased, when the patient is already in a state
of great dariger, need not be insisted upon.
As to the safety of the practice with regard to
the child, that likewise seems to be assumèd upon
no very substantial grounds ; at least if we may
judge of the probability of saving the child, from
what has happened in cases where distortion exist-
ed, we shall not bave much encouragement, so £ir
as the child is concemed, to extend the practice to
such casès. If indeed the majority of the child-
ren had been preserved, sometbing might be said in
support of thè operation ; but it seems, that only
Tiineteen children were born alive, and capable (^

These are indeed suflSicient to justify the prac-
tice, when there is a moral certainty that the child's .
life must be inevitably lost, unless this mode b^
adopted ; but there does not exist the same reason
fpr resorting to it, when the child's lifè is not so
cextainly exposed to danger»
142 ' CASE» aF LABÒÙR
Itpoìi the whole it appears to me, that tìie ad-
vantage either fo mother or child from such an ex-
tension of this practice is extremely problematìcal,
wKile to admit of it wouid be opening a wlde door
to a dreadful abuse of the opefation, by the igno-
rante or the unprincipled. I must take leave there-
fore to express my humble opinion, that the induce-
ment of premature labour by art ought to be strictly
confined to those melancholy cases of distorted
pelvis only, for which it was originally recom-
mended.
In order to guard against any abuse of this me-
thod of practice, itseems expedient, tbat somefixed
rulés of conduct should be observed respecting its
àdòption. What these rules ought to be, I do not
presume to determine, but shall contpnt myself
with subjoining such limitations and cautions as ap-
pear to me to be indispensable.
1. As the primary object is, to preserva the life
of the child, the operati©» should never bé under-
taken, till seven compiete montks of utero-gestation
have elapsed, and if the pelvis of the mother be
not too much contracted to allow of it, the delay
of another fortnight, will give a greater chance to
the child, of surviving the birth.

4. The operalion ought not to be performedy

5. If upon examination, before the operation is
performed it should be discovered^ that the present-
ation is preternaturale it might be advisable^ to de^
fer it for a few days, ^s it is possible, that a spon-
taneous alteration of the chiid's pòsition may take
placet; particularly if the preaentation be of the
superior extremities.

7. In order to gìve every possible chance for
preserving the life of the child, it wiU be prudent
been known to happen. Dr. Denman bas known more than ooe
instance of the presentation of the head being exchanged for the
arm. Introd. to Midwifery, p. 450. Mr. Burns mentions a ca^
where theshoulderwas exchanged for the head, Princip. of Mìd-
wifery, p. 218. ,Dr. Merrìman, senior, was about to puncture the
membranes in a wooian who bad a distorted pdvìs, when he dìs-
tÌQCtly felt the child's band through the membiianes, just witbìn the
OS uteri ; he therefore deferred the operation, and at the end of
three or four days, examined again, and discovered that the band
vas retracted and that the head presented. He now performed
tìie operation, which was completely successful. Silber tells of a
case in which the elbow presented, but in tbirty-six hours, tbe
head occupied its place. *' Pater meus explorans per vaginam Poe-

ALTHOUGH kino has been, for a considerable
lime, well known as an article of the materia me-
dica, there stili remains, some uncertainty respect-
ing its origin. It is indeed generally supposed,
that there are three substances, somewhat dif&r-
ent from each other, to which this name is applied.
The one which has been the longest known, and is
perhaps the most frequently met with, comes from
Africa; but we are entirely ignorant from what
plant it is derived. A second species is said to be
extracted from the Eucalyptus resinifera of New
South Wales; while a third variety, which isbrought
from the West Indies, has by some writers been as-
cribed to the coccoloba uvifera, and by otliers to
the mahogany*. Having obtained a quanti ty of
the bark of the coccoloba uvifera frp^p a friend in

citlydepend, I embraced the opportunity of examin-
ìng its properties, and comparìng the extract form-
ed from it wìth the kino usually employed in medi»
cine»
The bark appeared to have béen taken from
branches of from one to two inches in diameter» and
was partially roUed up, much after the manner of
the common Peruvian bark« No part of it was
more than ^th of an inch in thickness, and some
specimens considerably thinner. It was lined
with a fine reddish brown cnticle, while the rei^t of
the bark was of a L'ght yellowish brown coloun
The extempl sur&ce was clean, and nearly firee from
any protuberances^ but in many parts it was
marked with slight longitudìnal fìirrows. When cut
transversely, the extemal part of the bark, for about
one quarter of its thickness, exhibited a coarser tex-
ture than tb^ remainder, and could not he reduced
to an equaUy fine powder, It had scarcely any
smeli ; when chewed and kept for some time in
the mouth, it produced a moderate degree of bit-
temess and astringency, with a slight. mixture of
an aromatic flavor.
A portion of the bark reduced. to fine powder,
from which a little of the coarser part had been
separated, was mixed with 40 times its weight of
water, atid kept for an hour at the beat of 200*. :

found to bave dissolved *4*2 of the powder-; the
residue was of a redder colour, and of a more
spongy texture than bèfore the experiment. The
iniusion seemed to retala ìtd transparency until ali
the water was evàporàted ; the extract wias hard
and brittle, and of a very deep reddish brown co-
lour. It was softened by beat, and reduced to a
half melted state. From what was observed during
the evaporation of the infusion, it seems that wa-
ter has the power of retaimng in solution almost an
indefinite quantity of the extract, although when
heated with the bark, it will' Hot originally take up

different reagents, and by way of comparison, simi-s

commonly used in medicine, and which appearéd
to agree nearly with the description of the variety
that is brought from Africa*. By being heated

opake as it cooled, but by filtration it was rendered
nearly transparent, Its colour was very different
from the infusion of the coccoloba, the latter being
brown with a tinge of red, while the kìno was red
with a sKght tinge of brown. The reagents em-

* The jiticture of tfie icoccoloba baiale was not afc
fected hy the additìon of water. • Jelly and the
oxysulpbate of iron threw down precipitates nearly
similar to tliose ftomthe watery infusion, but the
mnmte of titì had no -effect. A quantity of the
tinctui^e was 6l<;iìwly evaporated, and a resàduum
was òbtained which was brittle, and of a browneir
colour than the extract from the ìnfbsion. It ap^*
peared to be scarcely soluble in cold water, but in
hot water the greatest part was dissolved ; the solu-
tion became muddy asit cooled, ìt was rendered
transparent by beat» and again grew opake when
the beat wa» witìidrawn. It was then filtered, and
an infusion was pbtained which was nearly trans*
parent, and of a light brown colour. . The tincture
of kino being treated in the same manner, a rci^
siduum was òbtained, which was of a deep rad co#
lour, and of a mcHre .fiiable texture than the kino
itself. This residuum was, for the niost part, rea-
dily soluble in hot water, althòugb a small portion
of a black substance remained undìssolved. Thia
part was soluble in alcohol } and the solution was
not precìpitated by water. Comparative experi-
ments were then made upon these twoinfusions, by
adding to each of them the same eight reagents as
in the former instance; the efiècts were nearly simi«
lar to those mentioned above.
A portion of the residuum of the eoeccdoba, after
the action of water upon it, was then digested in

lost abcmt ^th of its weìgbt. Wlim the converse nf
Ihis experimeot was tried, i* e. whea the residuuitt
of the tincture was digested in water^ scarceiy any
effect was produced, the ìnfiision was aligfatly ting<*
ed by the oxysulphate of inm, and a very mìinite
precipitate was produced by jelly»
From the above experìm^its we may conclude,
that the extract of coccoloba is a substance of the
same nature wìth the kino used in medicine ; but
ihat it diifers j&om it so fax as to show» that thejF
are not derived from the same plant They are
very similai* in their esternai appearauce ajad phy-
sical properties ; but there is an obvious difierence
in the colour» bofb of the infìision and tincture.
The eiiect of the reagents is also difierent ; jelly
producìng a brown precipitate with coccoloba, and
a reddish one with kino ; iron a black precipitate
wìth coccoloba^and an olive-coloiired one with kino*
The efibcts of lime and sulphuric acid are much
less with kino than with the coccoloba : there h
no precipitate thrown down either by antimony or
the subcarbonate of potash from kino, while the ei^
fect upon the coccoloba is very considerable. The
soluble part of the coccoloba bark seemsr to consist
principally of tan, which is in ali respects similar to
the tm of the gali nut ; while thè tan of which
kino is chiefly composed, resembles that of rhata-
ny, and the substance which is artificially prò»

cocodU>ba bark is accpiopankd, as is usuElly the
case, with gallic acid^ and it likewise exhibits those
propeitie^ which bave been ascrìbed to the presence
of a spedfic vegetabk product called extractive ;
btit the eKÌstence of this I thìnk has not been di^
tinctly proved*. The substance procured by èva-
porating the watery infusion, is in.pàrtrenderedin-
sohible by the process, and the same would appear
to be the case with kino, as it is probable that kino
is fbrmed by evaporation, from an infusion or de-
coction. Its appearance indicates that it has un-
dergone this kind of operation, and I am not ao
quainted with any instance in which a substance,
composed principally of tan, naturally exudes &om
aplant.
That part of the coccoloba which is soluble in
ulcohol, and not soluble in water, was examined by
evaporating the tincture formed from the aqueous
residue of the bark. By the evaporation, a sub-^
stance was lefìt, the greatest part of which was of a
greenish brown colour, and along with it a little
reddish matter.. Its odour was fragrant, something
like that of the balsam of tolu. Water that had
been digested upon it produced only a slight efièct
yiith isinglass, and the oxysulphate of iron. Neither
the tincture of this substance nor of the entire
extract of coccoloba were precipitated by water.

pffer as a true description of the earliest and most
simple state of spleniti», I beg leave to cali their
attention to an example of that afFection in its more
advanced stage. In this part of its progress the
diseasie may be expeòted to bave assumed its in*
flammatory chajacter, and to correspond with the
account of writ^rs on splenitis. Even in this
stage I believe that the treatment may be improved.
It appears that the opinions of physicians are not
settled respecting this disease j since the treatment
of the foUowing case had been exceedingly various,
and though it was directed by men of great intelli-
gence and experience, the pian that was successful
bad not made a part of their practice; and it must

be inferred, that continued daily purgation had
not been yet considered an effectual means of cure
in splenìtìs.
The subject of this case is a young lady about
25 yéars of age, whose disease was finft noticed in
the year 1 808, during a state of great uneasìness
of mind. She had been sensible of debility and
shortness of breath in the spring of this year, but
in the summer she was free from complaint. In
the month of September she began to complain of
an uneasiness across the pit of the stomach, below
the stemum, from the spurìous ribs of one side to
those of the other side, and imder them. The
right side was most affected, but she could not lie
on either side. The pulse was not disturbed. Mr.
Harcourt who attended the pat^ent observed, that
it varied from 60 to 70, and only became quicker
on the advance of thè diseiuse, in fits of pain and
dyspnoea. In three weeks she began to saffer pain
on pressure of the left side, and the right side be«^
carne more easy in proportion as this sensation in-»
creased. She now had frequent nausea and puking,
but an eager desire for food in the intervals of her
sickness.

In the middle of sammer there was an abatement
of severity in the symptoms for a short time.
In Septembfer the disease had again ìncreased In
vìolence. To tìie symptoms akeady enumerated
there was added a new form of dyspnoea. It now
carne on by spasmodic fits, and it also distressed

In November she had some mitigation of her sui^
ferings, but there was no suspension of her com-
plaìnt. On the attacks of spasm and pain the pulse
roseto 120; at other tiìnes itwas seldom higher

I7th, 1810. About two years from the beginning
of her'complaint, which had new greàtiy increased
in violence, and was attended by great depression
of mind« The attacks of spasm were particularly
distressing : fòr these she took large doses of anti-
spasmodic and opiate medicines, which gaVe relief

iless succeeded; and the pain of the leftsidé greW
insupportable^ Wìth more or less of these symptoms,
she h^ been unable to lie down for séveral mónthsy
and she had a heavy weightin the left ^e;. Upon
examination of the side» it was found to be enlarged
and painful : the eniargement was not promìnent
at a point, but dìfiused from the margin of the
£ilse ribs to the pìt of the stomach and backwards
to the spine. The 8th rib, and the lòwer ribs ap-
peared to be pushed forward. The least motion of
tlie body aggravated the symptoms : the pulse had
become as high as 90 between the attacks: the
tongue was raoist, with a whitish siuface, the skin
was naturai, the evacuations of stool and urine were
naturai.
. I prescrìbed pills composed of aloes with antìmo-
nial powder and extract of coxìium to be taken
every six hours, with a saline, draught* »She was:
recommended to bear the attacks as ùlt as possìble
without applyìng to opiates and antispasmodica.

On my next visit I found that she was beginnìng
to derive benefit from this pian. Tlje symptoms
had abated gradually from the first purgative ope-
ration of tìy medicines, which were contìnuéd with

spasms were less distressing in^violqpee aod dara->
tion, and she had seldom taken the anodyne
draught. The tension and soreness of the side were
much less. She was directed to pursue the same
medìcines.
May 5* 19. — She had continued to have five or
six stools dàily, and to discharge much urine, but
neither of these evacuations had any remarkable
appearance. The swelling of the side was more di-
minishedv The spasms were not so frequent pr
severe, and the dyspnoea and locai pain, tliough yet
Constant, were become bearable. The pulse was
96 only during theattacks. From the general
amendnient, it was determined to attempt the use
of a stom9.chic, combined with aperìents. An in->
fusion . of cascarilla was directed to be taken twice'

June 16, SO. — After a short trial of the stomachic
draughts, it had appeared that pain, general irrì*
tation, and dyspno^ were increased, and that the
bowels had not been so freely operated upon as by
the fórmer medicines. She. was therefore directed.
to resumé the aloetic antimonial pills, and to take
a saline draught with sulphate of potash instead of
that with infusion of cascarilla.

Jtdy 14, 28.— This pian of medicine having been
pursued through the month of July, ali her com-
plaints were considerably lesseried by the end of the
month. She lefl her room about this time.
August 1 1 • — She stili persisted in the evacuant
pian with continued good effect. The fulness or
general swelling of the side was gone, but there
was a perceptible thickness of the cartilaginòus ex-
tremities of the false ribs, and of their integimients,
with some tendemess on the pressure of these parts^
dose under the false ribs, and on their edge up to
the scrobictilus cordis. By the absence of the
swelling intemally, these extemal parts werè more
distinctly noticed as the seat of complaint. The
ade had been ipvariably more uneasy when the
bowels were less purged. She had, however, been
ttioved from four to six times every day. The pulse
was stili quicker than naturai, but it generally was
at 90 in a minute without much variation. It ap-
peared proper to continue the pian of medicine, by
taking pills of tartarized antimony and aloes every
liight, and a saline draught every moming.

Septemher. — ^At the beginning of this month the
tEermometer stood at 80, and in a few days after-
wards at 55 and 60, but she felt no return of dis-
ease, and could now lie very well ori either side.
The pulse was 84, The pills and draught had prò-
cured not less than four motions every day, which
had no extraordinary appearance. She had a good
appetite, a&d the power of ta}ang exercise vntk9Vit
&tigue or dyspnoea.
: As the disease had manìfested itself most in the
qxring and autumn» I had looked to the advance of .
the piesent season with anxiety, but firom the, fa-
vorable state of the case at this peciod, I begau to
expect that ìiie patient imght escape a relapse.
Sbe was not, however, so &r confirined in faealth,
or the disposition of the affected organ was not so
£aut changed, as to realize my hope.
"Por several days after the 20th oi September, a
weight had been gradually increasing in the left
side, attended with some uneasiness in lyììig on the
rìght side* The head was confused and gìddy, and
ishe had a short and panting respiration, with chil-*
liness and beat at intervals. The pulse was 92.
She had lately used a fuller diet and more exercise,
and the menses were expected in a few days. I
hoped that this change, with the efFect of active
puFging, might reduce the action and fìihiess of
the vessels, and remove the attack. I prescrìbed
laiger doses of aloes united with calomel and a purg-
ing saline draught every morning. She was to take
a draught of camphorated mixture with camphorated
tincture of opium after the operationeveiy night, and
oftenerifnecessary. Thesemeansansweredverywell.
Intwodaysthe menses appeared in great abundance,
but with a naturai colour, and the patient was relieved
òom this short attack by the end of the month.

November lé.^^ln the beginning of this month
the disease retumed with some variatìon of symp-
toms, in consequence of taking cold. It had as-
sumed a more acute character, than I had observed
since the formidable symptoms gave way in the
spring; and it might have been mistaken for pleu-
risy by a person unacquainted with the preceding
circumstances. She had a severe cough, and a
pain in the side, where the complaint had been he-
fore felt. She had mach head-ache, sickness of the
stomach and rigors. The pulse was 1 10.
1 ordered a saline draught to be taken.every four
hours, and jhUs of extract. coloc. compos. and gam-
boge to be taken directly, and repeated according
to circumstances once a day. Twelve ounces of
blood were taken from the arm, which had the ap-
pearance of healthy blood : there was no size, and
the texture was good. The bleeding afibrded very
little sense of relief from pain, which extended from
side; to side^ but was felt acutely in the left side
under the false ribs. There was no swelling per-
ceptible extemally. In this state of things tlie
menses appeared on the 2lst of November, and
gave very speedy and almost pérfect relief. The
cough wasgone: she had no head-ache or sickness:
. the pulse was reduced to 85. She was directed to
take piUs as before, of aloes and tarta^zedfintimony.

At the end of this moDth, she was free from com-
plaint. The pulse was at • 80. She had a perspir-
ing skin, and evacuated many stools every day.
She was directed to continue the aperient pills.
It appeared to me that the disease was stogped
, in September by the evacuant medicines, and the
appearance of the menses, and I consìdered it
doubtfiil if the relapse would bave occurred in No-
vember if she had not taken cold. The attack ìxi
Noyember had 'the character of acute splenitis ii^
which the investing membranes were principally, if
not whoUy, the seat of the disease. TKis acute
state was favored by the increased irritability of
the organ iti consequence of its long, suffering,
and the continued appUcation of necessary treat-
ment j but it seemed to be the harbinger of a con-
fìrmed dispositìon to sound health in tlie part af-
fected.
Since the end of the yea,r 1810, this patient has
remained well, with the slight exception of feehngs
of uneasiness in the side on the approach of the
menses, which menstruation has always removed.
But she considers that the pills of aloes and tartariz-
ed antimony bave been, by their effect on the bowels
during the last year, a securityfor the confirm-
ation of ber health.

Semarks on the preceding Case.
1 bave considered this case as affordmg an ex-
ampie of an advanced state of splenitis. It might
be called the **Second Stage" when compared
with that disease which I had the honor of de-
scribing to the Society as a case of ** painful and
turgid spleen** in its most simple state, in tìie
earliest condition of this disorder tlie organ is sweD-
fed from the passive state of its vesseis, which re-
ceive a greater proportion of blood tìian they can
return. No fever accompanied this stage, nor waS
it the effect of fever, but an idiopathic afièction,
leading to inflammation by tension and irritation of
the membranes that invest the spleen. The means
of cure were experienced to be active and daily
evacuations, so persisted in as to become the prò-
bable occasion of disease, if they had not been es-
sential to the removal of it. A considerable iength
of ti me is necessary to the cure of this affection, be-
cause it is dependent on the weakness and passive
condition of the vesselsof the spleen, and its duration
must be in proportion as the return of their energy
and contractilè power is slow. If the second stage
of splenitis be made free from danger, it must re-
quire stili longer time before it terminates in a cure
than the first stage, as the disposition to a renewal
of vascular sweliing will be more confirmed by
time, and show itself periodicaJly.
The more advanced stage of this disease has
been often described, and too often furnished the
anatomist with obsetvations after death.
REMARK& ON SPL£^IS. 165
In the second stage the pulsa becomes quicker^
and it is long, in convaleseence, befof e it is re-
duced lo its naturai standard. The increased
pulse is produced by painful irrìtation ait first» and
next by the actual tension of the membranes, pro«^
ceeding to inflammation and adhesion- of adjoining
"paxts. The quickncss. of the pulse will assist in.
distinguishing the degree of progress of this dasease^
for it will be found, by reference to hisitories,, that in>
a great proportion of cases,^ tbere was no waming
c£ the growing mìschief in its earliest stage ; and
fhat painful aifection of the lefl side existed in xm^
ny other casesv long before fever was ìndueed,
though these ended fiitally.
Ib the first stage the patient can lie upcm the
left side, but not on the right side. In the second
stage it is impossible to lie on the side afiècted.
The spasmodic action of the (Maphragm is more
likely to come on in the second stage, and may be
much aggravated by stimulant treatment. Tbere
is no emaciation in the first stage of a morbid kind,
nor any qonsiderable emaciation in thè second
stage» notwithstandiog the large and continued
evacuations. But in the third and last stage of
splenitis, emaciation is always an attending symp-^
tom, combined with hectie or slow fever, particu*
larly in middle-aged aJad elderly people. In this
third stage diarrhoea supervenes, as well as dysen»

charges give temporary relief in many cases, and
óccur long before the énal event.
Besides the two cases which I-have submitted* to
the Society, it is right to observe, that I bave* seen
the result of many others during the last three
years, three of which occurred in young men and
the majority in women. Ali these bave concurred
to shew me in a satisfactory manner that drastic
purging, long continued, is the proper mode of
treatment. By this practice a young woman has
been relieved of a swelling of the spleen and epi-
lepticfits at the same time. The fits began with
the first symptoms of disease in the leff side, and
bave disappeared for the last year, during which
time she was gradually recovered from the swelKng
and pain.
Compositions of aloes and antimony were prefer-
red in the cases that bave been related, and gene-
rally in others, but not exclusively adopted: large
doses of neutral salts bave' however appeared
exceptionable when exhibited daily, as they bave
occasioned flatulence and depression. But aloes,
extract of colocynth, and scammony withjalap,
bave acted without this inconvenience, and calo-
mei has been combined with these, at intervals,
producing more efFectual discharges from the bow^
els : tartarized antimony in such minute doses, as
not to puke, has always appeared to increase the
beneficiai efFeCt of those combinations.
REMARKS QN SPLENITI».
167
This idiopathic disease afiects femalés more than
males, and they bave been alwayF relieved in a
signal manner by the flow of the menses : this fact
taay give rise to an idea somewhat speculative, but
not wìthout supporta that a particular correspopd*»
enee or sympathy of action, may exist between th©
spleen and the uterus. Each of these vascular or*
gans bave a structure which yields to extension and
contraction with less disturbancB of the whoje ha»
bit than happens from equal changes in otherorgans,
and wherever splenitis is relieved by nature or art,
the ìnferior vessels of the body receive more than
their usuai quantity of blood, which passes from
the uterus or the intestinés : a fact agreeing with
the 48tb. Aphor. of Hippocrates, lib. 6. " Tot(ri trvM'

The progressive efFects, and the cpmpUcations
of this complaint may appear after death ; bùt it
is obvious that no certain conclusions can be drawn
from dissection^ respecting the two first stages of it,
and particularly that the condition of the organ int
the earliest and most simple state of its sufFering
cannot be prpyed by anatomical examinatipn.
Splenitis, complicated with extensive visceral
obstructions, has been very frequently the effect
of remittent and endemie fever; but a tumid spleen
occasiòned by this cause, cannot afibrd any reason-
ìng respecting the idiopathic disease, whicb in its

▼ery àiflferent cha^acter. The difference between
Àuch Gomplicated affisctions and tbìs sìmple dìsease
mll appeal^ mfficiently manifest io those who con-
sult the historìés of Lieutaud and Morgagni, but
particulariy the recent descriptions of Dr. Davis
in his treatisé on the Walcheren fever.
Arettóus Bàyè, that the disease is fatai to élderiy
péople, but that it is not so dangerous to youth. Dr.
Heberden's later observations confirm the assertion
òf Arètaèus respecting the tendency of the disease in
people advanced to middle age, in whom it is fatai
in six months.
It is very importànt at every period of lifc to dis-
tinguish the disease in its early stages ; we are not
to expect the presence of pyrexia, and extemal
swelling to make the case obvious. Pain of the left
side, and inability to He on the right side, are often
the only i^gns, aiid if these two symptoms exist
without fever, there cannot be much doubt respect-
ìng the seat of the disease, fbr a painful disease of
2^ny other organ of the left side would be accom-
panied with fever, aftd other symptoiìis of consti-
tutional sympathy and irritation.
The spleen has been dei^crìbed very gènerally as
» passive organ, and not readìly sensible, to inflam*^
matory irritation. (SeeDr. Pemberton.) Tliiscfaa*
racter can occasìon little wonder, if the structure
RBMARKS ON SPLENITE. 169
and oeconomy of the spleen be well consìdered.
(See Malpighi and Hakely &c.) The absence of
pyrexia in the early part of splenitìs does not ap-
peal so remarkaWe as it does in cases of the stran-
gulated intestine, in which Dr. Baillie says, ** The
pulse is sometimes not increased in frequency be»
yond the stand^d of health, and yet the inflamma-
tion of the bowels has been discovered afterwards
by the operation to be very great/*
It is impossible to say how far a continued ap-
plication of purgatives might bave ahswered in ad-
vanced cases, or in thè first stages of cases, which
ended fatally, as ibis practice has not been follow-
ed in any instance within my knowledge. In a
case detailed. in the Edinburgh Journal, it was
found that purging was the best means of relieving
the patient, but it was only practised at intervals,
and it was accompanied by the use of medicines
which must bave acted upon an opposite principle
to that of evacuation, possibly counteracting its in-
fluence. Similar cases are to be found in Morgagni
and lieutaud, and it must appear from the result,
that it was a third stage of splenitis when the inge-
nìous writer first saw the case, the distinguishing
character of the early part of the disease having
been lost. The patience and insensibility of the
organ is so remarkable that changes that must bave
been of long standing, bave been ohly discovered at
the death of the patient.

1 70 REMARKS OX SPLENITIS.
A person met with sudden death from accident,
and, as it is related in the ^* Acta Parisiensia/* bis
spleen -was found stoney in its internai structure
withouf any other mark of disease.
Enlargements are recorded by writers to bave ex-
isted without notice of the change, and fever, or
severe pain only carne on to alarm the patients
after a long period, thougb these diseases terminated
in death,
It is therefore true in the distinguishing of sple-
nitis, that the disease may bave made great progress
without observation. Pain may bave been felt
without, swelling, and swelling without pain, and
both may bave fexisted without the pulse having
been disturbed for a long period in the first stage of
splenitis; but on dissection, the spleen, after such
previous circuinstapces, has been found iporbid,
and the only diseased organ.

They are attached to the orifices of the ureters, and
are seated in the bladder. In health they are the
Instruments of a very peculiar organic action, and
in disease the cause of most distressing complaints,
Before I proceed to describe the anatomy of this
part of the bìadder, the subject seems to require,
that I should give a short historical review of the
opinions respecting it.
1*72 ON THE MUSCLES
Of the parts hilherto described as seated at tJie neck
qf the bladder-^^La trigone de la vessie — La
Luette — Uvula Vesicce — Corpora carnosa Mor^
gagnL — Third lobe qf the prostate^ S^c. 8^.
In the plates of De Graaff there are represented
certain folds extending forward from the orifices of
the ureters, where tbey terminate in the cavìty of
the bladdèr; and at the lower part of the orifice of
the bladder, there is a tubercle fein-ily indicated.
The same appearance is represented by Bidloù. In
Santorini also the naturai appearance of these parts
is accurately delineated. Morgagni expresses him-
self to this purpose: " at the points where the ure-
ters terminate in the bladder, there arises from each
of them a thick round compact fleshy body, which
takes a direction towards the orifice of the bladder.
These two bodies having proceeded a little way,
are united, and proceed forward, terminating in
the Caput GaUinaceum*.'*
^ Santorini t gives the same description of thése
pai'ts as Morgagni has dehvered.
Lieutaud describes these bodies under the term
Zia trigone de la vessie. The learned Portai is in-
correct in saying that Lieutaud was the first anato-
mist who has given their description.

Portai has tkus dcBcribed the Trig<me: at
the lower part, the uiternal tunic of the bladder
adberes to a triaagular body of a cartìiaginoue hard-
ness, and tiiìs body is always prominent in the ca-
vity of the bladder, especially in old meo* He
proceeds to say, that, at the extremity of the trì-
jxn^e, baclcwards, the orifices of the ureters open;
and at their anterior extremity, there is an eminènce
slightly protuberant, to whidi lieutaud has given
the liame of Luette.
This account leads me agaìn to refer to the plabe
of the excellent anatomist Dominico SantorinL In
his secoiìd table the Luette and Trigone are accu-
rately represented.
He h^as the fdlowing explan^tion on the letter L
" Vesìcae urinai oscid^un cui prominulum corpus
^* pr«6gitur quod in afièctis vesic» ac prominet ali-
** quando ut urinai iter prorsus intercludat.*' This
refers to the disease with which Mr. Hunter and
Mr. Home bave made us familiar.
The expression of Santorini recalls us again to
the remark of Portai : he say s. ** I bave found in
" old men who bave suffered retention of urine,
" the Trigone de la Vessie so enlarged, especially
" its tubercle, in the form of an Uvula (Luette)
" that the orifice of the bladder was shut by it*/

Sabatierfólìows his countryman in his. description
of thìs part ofthe bladder, but adds; " The Tri-
gone and Luette are the most sensible parts of the
bladder; wHich is the cause why a stone lodging
bere produces extreme irritation, while if it
" lodges in any other part of the cavity of the blad-
" der, it causes little inconvenience :" he adds,
" The uvula (Luette^) which terminates thci ante-
" rior angle is very subject to swell, and then it
*' rises in the forni of a round tumor which fills the
^' neck of the bladder, and opposes itself to the flow
" of urine*."
Desault^ speaking of the tumors which grow in
the bladder, has this expression. " Le sommet de
" ce viscere n'en est pas plus exempt que son bas-
*' fond ; mais ce sont particulièrement ceux qui crois-
" sent près de son col, et que quelques auteurs ont
** pris pour un gonflement de la luette vesicale, qui
" occasionnent la retentìon d*urine.**
This sentence, which betrays the imperfect know-
ledge which Desault had ofthe disease, isfollowed
by other unequivqcal marks of unconfirmed prin-
ciples and practice: and the whole chapter stands
in reraarkable contras t with the publication of Mr.

OF THE URETERS. 1 75
m
In Haller's Ekment. Physiolog*. we have a de-
scription following that of Morgagni under the tidè
Colliculi ab Uteribus in Urethram prodmiu '
m
These authorities discussed, we come now to the
more modem observation of Mr. Hunter.
\
Mr* Hunter i has described a small portion of
the prostate gland which lies behind the very be-
ginning of the urethra; and this he describes as
subject to swell out liké a point into the cavity of
the bladder, where it acts like a valve on the mouth
of the urethra. This can J^e seen even when the
swellìng is not considerable, by looking upon the
mouth of the urethra from the cavity of the bladder.
It is ìmpossible to mistake this; the swelling he
describes is the Uvula Veskce or Luette of Lieutaud.
The observations of Mr. Hunter, then, go to inform
US, th^t this tumor is of that part of the prostate
gland which is below the urethra, and betwixt the
lateral portions of the gland*
This discovery carries us back to the great ana-
tomists in whose works we find the elements of ali
oui: present knowledge. Morgagni has very fiilly
described the part of the prostate gland which Mr.
Hunter mentions, and which he discovered to be
the seat of this dangerous malady. Morgagni thus
describes it :

Anatomy of the Neck qfthe Bladder.
I bave now to lay before the Society the anatomy
of the neck of the bladder in man.
On dissecting up the inner coat of the bladder,
there are seen two strong fleshy columns, which
■

t Med. Operat. T, II. p. 72.
OF THE URETERE 177
deséend from the orifices of the ureters towards
the orifice of the bladder : they unite and run to
wards the prostate gland. On the surface, towards
the cavity of the bladder, they are denser by the
union of the inner coat of the bladder, but they
are fibrous, and this fibrous structure is made mani»
fest by dissection from be^ow. They are larger and
firmer, but of the same colour and structure with
the fleshy eolumns of the Detrusor urincv. The
variety which we find in their length according
with the degree of contraction of the bladder,
proyes their muscularity. Whatever expites* the
action of the bladder increases the size of these
muscles in a remarkable degree, and they always
acquire a great increase of power and size when
the miiscular coat of the bladder, becomes more
distinct and powerfuL In some of my specimens
of^ diseased bladder, I find the cause of this to be
stòné in the bladder ; in others, an ulcer ; in many,
stricture ; but always irritation and the necessity
of continuai action of the bladder are attended
with an enlargement of the muscles of the ureters,
When. contracted, the course of these columna
is distinguishable ali the way from the mouths of
the ureters to the beginning of the urethxa ; and
there, at their union, they heave up the inner coat
of the bladder producing the appearance of a tuber-.
de at the lower part of the orifice of the bladder *r
^ It ià this appearance presentéd bytbe muscles in a sfate fd con-
traction, which has led so many of oiir best authorities to confour>4
it with the disease of the third lobe of the prostate jìaud,
VOJ-. ni. N
17S ON THE IVIUSCLES
It is stili the form of the inner coat whicli
makes these fteshy columns appear to terminate for-
ward in the caput gallinaceum ; which theydonot;
they only take a firmer insertion. Where these co-
lumns unite they are most fieshy, and their fibres
are more intricate ; then, directing theu* eourse to-
wards the lower and backmost part of the prostate,
they degenerate into tendon, and are insertod into
tlie portìon called the third lobe of the pròstate. '
Althougb I have described the course of these
muscles as proceeding from the back part &rward,
because it better corresponds with the first view we
have of them, yet, I believe, it is more correct to
consider their connection with the prostate gland
as the fixed point, and their connection with the
extremities of tliie ureters as their insertion.
USE. — The use of these muscles is, to. assist in
the contraction of the bladder, and at the same
time to dose and support the mouths of the ureters.
The surface of the bladder where it covérs their
union on the inside, is endowed with an exquisìte
sensibility, which is a prò vision of nature, fbr theii*
ready and instantaneous action on the stimulus to
|)ass the urine. It is bere that is seated that sensi-
bility which produces the naturai cali to urine, and
bere also is the seat of diseased irritations.
It will be observed tliat the orifices of th^ ureters
are not closed by the contraction of the musculftr
QF THE URETERS. 179
fibres around them. They are defended against
the return of the urine by the obliquity of their pas-
sage through the coats of the bladder. It is well
known that the extremity of the ureter enters
through the coats of the bladder obliquely, and
that in consequenqe of this, there is a valvular
action in the coats of the bladder which prevents
the regurgitation of the urine into the ducts of
the kidney.
But if we look to the a^oining diagram, and
consider thésubject, we shall find, that inpropor-
tion as the bkdder contracts, this obliquity must
be diminished j and further, if we reflect that the
coat which contracts is òn the outside of the ob-
lique passage of the uretei*, we shall conclude that
without some counteradting power on the inside of
the bladder to draw down the orifìce of the ureter,
the obliquity of the passage would be lost. These
muscles, which I bave now described, guard the ori-
fiìces of the ureters by preseiTing the obliquity of
the pas^e, and by pulUng down the extremities
of the ureters according tp the degree of the con-
traction of the bladder generali/.

The membrane which covers these muscles, is
the seat of that sense which calls the muscular
coat of tfae bladder into action. Of this we may
he sensible in passing the bouglé^ and stili more in
passìng the uréthra sound. As the instriìmeht is
passed down the uretfirà, there is a siqkéning sen-
sation ; as it passes the caput gallinacèum, the na-
ture of the pain is changedj and, lastly, in pass-
ing it over the surface of the triangular elevation,
produced by these muscles, there is experiénced
thè familiar sensation of the cali to pass urine. If
it were doubted that bere, in a particular manner,
* is seated that sensibility, which calls the bladder
into action, the efiect of a stone falling upon
the part is sufficient proof. When a patient has a
stone in the bladder, there is pain and excitement
while it rests in this place, and relief when it
lodges elsewhere. The reason why this part is
possessed of such sensibility, I apprehend to be,
that the muscles of the ureters may, as it were, te
the fifst ^armed, in order to guard the mouth of
the ureters, and preserve their obliquity during
the action of the bladder*
its operation is to draw down the orifice of the Ureter C. in pro-
ppttion as the bladder coutracts^ by which, me^ins the pbliqviitT qÌ
the passage is p^ ^sei:ve4.
là2 GX THE S^X^LES
Aftim in Disease.
When the sensibility in the iusat of tìiese oms*
cles ìs increased by disease, ànd the increased ien»
«bility is accompanied vith a continuai actipn of
the muscles, tifie prostate gland mmt fsmSkt xxsmxxA
exciteinent. The naturai prominenee {wm^ by
the piusclés being directly over the third lobe of
the prostate, and theìr chief attachment being alsa
to this third lobe, we may pecceive how it bappena
that this part is sometimes enlarged without tìie
body of the prostate gland partaking mui;;h in the
disease, When there is an unusual fdm$ of the
bladder, these muscles are the seat of it ; and as
their united extremities are attached to the lower
and middle portion of thè prostate gland, they
must, I think, promote the growth of this portion
in a direction toward^ the cavity of the bladder*^
This will produce the true tevula vemasj the pen-*
dulous tumor in the neck pf the bladder resesi^
bling the uvula of the palate^ Thia tumor bangs
into the cavity of the bladder, and falls like a vajve
upon the orifice of the bladder, proving a most trou-
blesome and dangerous obstruction to the urine.
' But whilst I state this às an opinion, drawi^
from the consideration of the parts in their natu^^
ral state, I must also submit the naked facts. I
have, in my coUectipn, two specimens of the dis-
pase of the third Iqbe of the prestate, where these
muscles are remarkably strong. I have, on the
OlP TtìÈ URETERS. 183
other band, soiAe specimens of diseased bladder,
where thè muscles of the ureters are enlarged;
aftd ótily in one of these ìs there a beginning en--
largement of the middle lobe of the prostate
glaiìd.
1 have many specimens of bone distorted by the
action of the muscles ; and many, where, at the at-
taehments of the tendons, the bones are dràwn out
iftto l^pines atid tubercles. We may say, such ìs the
eflbct óf the muscles ; but though the growth of
Buch Spinès OF tubercles be the effect of thè action
of the muscles directly, yet thése spines will not
be formed, unless when the bones are at thè same
tiiiìe sufiering from disebse. So in considering the
action of the muscles of the ureters, as influencing
the growth of the prostate in a particular direction,
1 do not imagine that the muscles will do this
merely by theif mechanical effect, There must b^
alsò a disposition to disease in the prostate ; and if
disease be not present, the irritation of the bladder
wiU continue even till the death of the patient,
without afiecting the growth of the glande
On the extremities of the ureters, in the dis^
easèd action of the bkdder, the contraction of
ihèse muscles ìs converted from a salutary in«
fluenc€, to one which aggravates disease, Thòy

vis of the kidney, and influence the kidney itsélf*:
thus increasing the extent of the kx:al disorder,
and consequently its influence on the constitutiòn»
- Such consequénces as àrise froin the irritation \
and action of these muscles, are to be reKeved by j
removing the cause ; by assuaging the sensibility
of tlie surface of the tuberclc, and by drawing off" |
the urine. When we know that this spot on the
lower part of the orifice of the bladder, is the seat
of that irritabiUty which is so distressing, we see
that it is practicable to effect it by the use of the
bougie. By the introduction of the catheter, the
urine is let off without hindrance from the valve :
the distressing excitement of the muscles is not
perpetuated, and the prostate subsides from its ir-
ritation*
\ »,
This practice, though a direct deductiòn fix)m
the examinatìon, I Jiave made, is no more than the
advice given to us by the bést authors.
Thus we see that a small tuhercle was painted
by De GrafF, and described by others, but the na-
ture and origin of the tuberete was miscoiicdvéd.
Anatomists were calUngit uvula vesiccBy as if that
naturai prominence was the same with the ttimar
of this part of the bladder. We find that the dis-
ease called , wrw/iz r?e5/c«?, is nootherthan that oc-
casioned by the enlargement of the third lobe of
the prostate gland. To Mr. Hunter and Mr.
OF THE UEETEM* 185
fiome, we are indebted for a full knowledge of
the nature of this disease. It has been objected
to Mr. Home, that he ìs in vain making that inr«
portant, which the great anatomists of ali ages
faave failed to discover, or* bave neglected to no-
tice, I bave shewn that the thiid lobe of the
prostate was known to Morgagni, and that it^was
a subject of discussion in his day. We bave suffi-
cient evidence (even on this very subject) of the
difference of a fiict being noticed in the elaborate
-Works of Morgagni, and of its being familiarlj
and practicaUy known to surgeons. The third
lobe of the prostate was qui te forgotten, the con-
sequence was that we were igjQorant of the nature
of the most fatai disease of the bladder. It would
be disingenuously reserving the circumstance,
which drew me to attend to this subject, were I
to omìt the mentipn pf the late work of Mr. Home,
or rather his originai paper on the anatomy of the
prostate gland. I- acknowledge both the merit
and the necessity of what he has written : for the
observation of Morgagni, andthehint of Sabatier,
were forgotten both bere and in France, until the
subject was distinctly and practically brought fof-
ward by Mr. Home. Even the latest French au*
thor, Richerand*, stili ,speaks of the enlargement'
of the anterior angle of the " trigone vesicale/*
and the growth oi fungosities near the neck of the
bladder, obstructing the course of the urine.

ON THE liTUSCLES OF THE URETERS.
It Stili remained to be explained^ why the small
part of the prostate gland, the thìrd lobe of Mr.
Home, shouid be so frequently eniarged, without
the allection of the body generally being apparent,
or why this pari shouid enlarge more rapidly thati
the rest of the gland. It was in the prosecution
of this inquiry, that I dìscovered the muscles of
the ureters, and after ascertaining their nature, I
iKaw through the obscurities of authors, in treating
of the diseases of this part of the bladder ; so that
in speaking of the enlargement of the anterior ex-
tremity of a naturai tubercle, they were deceived,
and that. in treating of the woulaj they were de«
scribing éhe diseased prostate gland.

some of the cases the gali bladder adheted to, and
broke into, the colon ; in some abscess was formed
extemally, which broke, discharged gali stones,
and remained fistulous ; and in other cases they en-
tirely healed. The symptoms which distinguish
this speci es of tumor from others, are detailed
with the singular sagacity which marks the writ-
ings of that great sui^eon.
Although in the following cases, the gali bladder
was not immediately concerned, they seem so evi-
dently allied to the subject of Mons. Petit's Essay,
that it is impossible to avoid referring to ìt.
*
A lady, about fifty years of age, was afFected
with great pain, which was described to be in the
Stomacb, Constant sickness, and a costi ve state of
the bowels, for which she took such medicines as
were prescribed by ber physìcian. These symp-
toms had continued for many wieeks, when a tu-
mor, evidently contàining a fluid, presented itself
just above the right groin, which I was desired to
see. The preceding history, the want of surround-
ing inflammation which shouid bave characterized
a simple abscess, and the recoUection of Petit's*
paper, induced me to decline opening the tumor.
* It will he rcmarked by those who are not awareto how great
a size the gali bladder will arri ve, that the situation of thè tumor
dfstlnguislied it from such an affection. I may therefore ohsen-e,
that there is in the coHection of St. Thomas's Hospital, a human
g«B bladder« wbicb« I suppose, \iould contain at least three pinta
of fluid. 1

I could not suppose it was a lumbar abscess, the
oiìly other disease for which it could easìly be
taken ; and even the propriety ,of opening such
tumors is, I think, by no méans fully established.
A poultice was therefore applied, and in aboutten
days it broke, and discharged a consìderable quan-
tity of discoloured matten The wound became
cxceedingly irritable, the granulations were loose,
indistinct, and dark-coloured, and the patient's
health much impaired. She was àdvised to go into
the country, and some time after her departure, I
was informed that the complaìnt had assumed a
difièrent charactér, that the discharge had become
foetid, and that the caraway-seeds in some cakes
she had eaten, Were occasionally seen with the dis-
charge on the Knt covering her sore. Soon after
this, she retiìmed to town, and another abscess
formed and communicated with the preceding one,
iand the discharge became manifestly faecal. Mean-
while the functions óf the bowels were not mate-
iially imjieded. She had an evacuation daily, with
or without aperient medicine, but her health suf-
fered much from the irritable state of the sores^
which was considerably increased by attempts at
locomotion.
At this period of her complaint, when I was
examining the wound deeply with the probe, I felt
it senslbly strike against a hard body, which, with
some difficulty, I could move so as to ascertain to-
lerably its situation and size. I then enlarged the

fistulous sore with the bistoury, and, with a pair of
long forceps, succeeded in extracting a calculus of
an ovai form, the long diameter of which wa3 more
than half an indi. I did not think it necessary^
like Mons. Sajirau*, to remove the callous circum-
ference of the sore, but the operation was painful
and somewhat tedious, from the difficulty of seiz-
ing the' stone with the forceps. No fever of con-
sequence, or any other untoward circumstance fol-
lowed, nor was the faecal discharge more copious
from the enlarged wound, a circumstance which
jsurprised me. About this time her health began
to amend, and the discharge to abate. It was
found necessary a short time 'afterwards, to divide
the interval under which the two sores communi-
cated, and which by its friction kept the parts in
a state of irritation. The wound theh gradually
contractted, assumed a more healthy appearance,
and had nearly closed when she went into the
country^ and her health was so much improved,
that I bave no doubt, in a very short time her cure
was perfectly accomplished.
A woman, about twenty-five years of age, had
for some time complained of pain and sicknes»
in the stomach, occasionally more or Jess violent,
and the functions of herbowels were so imperfectly
performed, that for many months she had been
constantly compelled to bave recourse to purga-

CALCtJLUS VOIDEB FROM THE GROIK. 195
tive medicines : at last a tumor presented itself
which I was requested to see, just above the right
groin* It was evidently situated under the integu-
ments and muscles of the abdomen, slightly move-
able, and could almost be comprehended between
the fingers and thumb. There was an inflamed
line of above àn ìiìch. in diameter, extending ob-
liquely upwards, and towards the linea alba. It
was painful to the touch, and she had some fever.
The first impression on- my mind, was that it
might probably be an affection of the ovarium,
But^ her age, the preceding history, and the very
strong resemblance of the symptoms to the case I
have described, induced me to suspect that, un-
less it were prevented, it would have the same
progress and issue; for it was clearly, I think,
connected with the functions of the intéstinal ca-
nal. I therefore directed her to apply leeches to
the tumor, which was done four; or five times,
and to be smartly purged every morning. With this
treatment, tògether with rest, and a very low re-
gimen, the tumor soon became less painful and
smaUer, and in the course of ten days was so far
reduced as to cease to be inconvenient to her;
there was, however, stili a considerable indura-
tibn, .which could be discovered by hard presaure
on the abdomen.
It would have been Éivourable to the analogyv
which I yet presume wìll be acknowledged, of these

two cases, if a calculus, wherever it had been lodged,
fiad been discovered in the faeces which passed
ivhile the tumor was diminishing, But no such
concretion was seen, nor perhapsvery accurately
sought for, altl;iough I had said that very probably
it would be found in the evacuations.
^ ^ From the sìtuation and ali the circumstances of
the first case, I thmk there can be no doubt that
the calculus was the cause of the abscess, and that
it was lodged in the coecum, where that portion of
the canal is attached to the right side, and net,
like Petit's cases, in the gali bladder. The faecal
evacuations sufficiently distinguish the two diseases,
and the fbetor of the discharge shews that it was
not in the small intestines.
Had the abscess been opened artificially, I have
great doubt whether it would have terminated so
favourably, for the differeilce between a spenta-
neous wound, and one made by a cutting instru-
ment, is often ^reater than a priori might have
been suspected, more particularly ^ere a serous
membrane is involved in the operatìon ; and the
flow of fseces after the lancet, unlesis it had been
distiYictly foreseen and foretold, would, at ali events,
have been an embarrassing and unfavourable cir-
cumstance to the surgeon.

as thcy have not been translated ìnto any other lan-
guage, and as they have appeared to those who
bave seen them, to contain some new views, I
am induced to offer them to the Society, in the
hope that they will be received isrith indulgence.
I. Oftlie blood.
In most of the analytical researches on blood,
that of the bullock has been made the subject of ex-
periment. I shall therefore begin with the analysis of
the blood of that animai, and afterwards notice the
essential points in whicb I have found it to differ
from the human,
A. Buttoclc's blood^
Blood may be regarded as a liquid holding a co-
louring matter suspended in it, but not dissolved.
The first step in the process of accurate analysis
should therefore be to separate the suspended mat-
tar by filtration. But this method succeeds only to
a certain degree, and requires a time so considera
able, that the blood undergoes spontaneous changea
of composition before the separation can be com-
pleted: for notwithstanding ali possible care, the
colouring matter will either pass through with the
fluid portion, or by adhering in masses, prevent ali
further percolatìon, Another mode is that of allow»
ing it to subside by rest: but this alsó goes on with
extreme slowness: the clear supernatant liquor loses.
its red colour but very gradually ; and the colour-
less |>ortion is not capable of being coUected alone.
200 CHEMICAL PHOPIiltTtES
The usuai way of obtaining them separate is Ui
take advantage of the coagulation of the blood,
during which the fibrin enveloping the colouring
substance, presses out the serum. This; method is^^
indeed but very ìmperfect, as a iarge partion of
the serum stili remains attached to the red globules
in the coagulum ; but it is the only one that we can
employ.
I shall first consider the crassamentum, and its
two constituent parts, fibrin and colouring matter.
The Chemical Properties qf Fibrin.
Fibrin is insoluble in cold water. In boiling
water it curls up, and, after the ebullitìon has con-
tinued some hours, the water acquires a milky hue,
but no gaseous product appears. By this operation
fibrin undergoes a species of decomposition ; the
water in which it is b'oiled affords, by the addition of
tannin, a precipitate of white and distinct flocculi,
which do not cohere together by the beat, as those
produced by gelatìn. The evaporated liquid does
not gelatinize to whatever degree it may be con-?
centrated, and leaves a white, diy, hard and fri-
able residue, which is soluble in cold water, and
has an agreeable taste similar to fresh broth, and
^otally unlike the salt and acrid flavour of the
extrac t from muscles. fibrin, by Ipug boiling in
water, loses its property of softeningand dissolvipg
|n acetic acid*

pitatedby the addition of water } having often a very
strong and unpleasant odour. The alcoholic soluti*
tion leaves on evaporation a fat residue, which did
not pre-exist in the fibrin, and which, as we shall
find, is Kkewise formed by the action of al^ohol in
the colouring matter and on the albumen. Fibrin
heated in alcohol, retains' its property of softening
and dissolving in acetic acid.
S. By th? action of ether^ fibrin is converted in-
to an adipocirous mass similar to the preceding, but
in much greater abundance, and having a much
«tronger and more disagreeable odour. We are on
this account precluded from employing generally
edther. alcohol or ether in analytical experiments on
Itnimal substances»

4. In concentrateci acetic acidy fibrin becomea
immediatély soft, transparent, and with the assist-
ance of beat is converted into a tremulous' jelly,
By adding water and warming it, this jelly is com-»
pletely dissolved^ with the evolution of a small quan*
tity of azotic gas. The solution is colourless, of a
mawkish and slightly acidtaste. During its evapora-,
tion a transparent membrane appears on the surface,
and after a certain degree of approximation , th e gel ati-
nous substance is again re-produced; but this gela-
, ^ne has no resemblance to that formed by paste.
202 >CHEM1CAL PROPERtnCS
When completely desiccated it ìs a transparent mass
which reddens turnsol paper, but which without a
fresh addition of acetic acid is insoluble both in cold
and boiling water. The solution of fibrin in acetic
acid added toprussiateof potassorof ammonia, gives
awhite precipitate, without any separation of prussìc
acid, This solution will also produce a precipitate by
alkalies, but it is redissolved by a small excess of the
latter. Sulphuric, nitric, and muriatic acids afibrd
Kkewise a precipitate with this solution: and tìie
precipitate is composed, as we shall presently see,
of fibrin and the acid employed. If the precipitate
be laid on a filter and washed, a certain quantity
of this acid is carri ed off' by the water, and the re*
maining substance is soluble in pure water. The
sdiution contains a neutral combination of fibrine
with the minerai acid employed, which is mucous,
somewhat opaline, and of an acidalous taste. An
addition of acid will again precipitate it, and itthus'
often happens that an animai substance that has
been treated with a minerai acid and washed on the
filter, gives at length a clear liquor which becomes
turbid on falling into the acid liquor that had first
gone through. This phenomenon always indicates
the presence of the abovementioqgd combination of
a minerai acid with fibri», or with allfumen, which
appears to possess tlie same chemical properties a^
fibrin*.
* It may be oteervcd that the precipitate produced by nitric
acid, assumes a yellow colour, but has in other respects the same
pro^^erties as the two olhers.

4. In weakmuriaticacid^ fibrìn shrihks and gìves
out a small quantity of azotic gas ; but scarcely any
portion is dissolved even by boiling: neither does
the acid lìquor afFord any precipitate with ammo-
nia, or with prussiate of potass. Evaporated to
dryness a brownish residue is obtained, from which
potash disengages a little amtnonia. Concentrated
murìatic acid decomposes fibiìn by coction, and
produces a red or violet-coloured solution^
The fihrin that has been digested with weak mu-
rìatic acid is hard and shrìvelled. By washing re«
peatedly with water, it is at length converted into
a gelatinous mass, which is perfectly soluble in te^
pid water. The' solution powerfully reddens litmus
paper, and yields a precipitate with acids as well as
with alkalies. Fibrin has therefore the property of
combining with muriatic acid in two proportions.
The one gives a neutral combination soluble in wa-
ter; the other, a combination with excess of acid
which is insoluble, but which is reduced to the state
of tlie soluble compound by the action oppure water.
5. Concentrated suJphuric acid decomposes and
carbonises fibrin.- The same acid diluted with six
times its weigbt of water, and digested with fibrin,
acquires a red colour, but dissolves scarcely any
thing. The fibrin that is not dissolved is a combin-
ation of it with an excess of sulphuric acid. By
depriving it of this excess of acid, by means of pure
water, a neutral combination is obtained which is
204 CHEMICAL FROPEBTIDS
soIuUe in water, and possesses thè same characters
as the neutral muriate of fihrin.
6. Nitric acid of the specìfic gravity 1.25 digest-
ed with fibriQ, renders it yellow, and diminishes
itscphesion. The fluid becomes yellaw, and the
surface of the fibrin is covered with a small quantity
of fat formed by the action pf the acid. During
this operation elastic matter is disengaged, which is
azotic gas alone, and in which I could not discover
the smallest portion of nitrous gas. When the di-
gestion has been continued twenty.four hours, the
fibrin is converted into a pulverulent mass, of a
pale citron colour, which is deposited at the bottom.
of the Kquor. The latter ^>cing decanted off, and
the undissolved matter placed on a filter and washed
with a large quantity of water, the colour changes
in proportion as the acid which was in excess is
carried off, and the mass acquires a deep orange
colour. Even vòen the affiision is continued J:ill
the water gives no sign of acidity, the orange mass
has not yet lost the property of reddening litmus.
This yellow substance was discovered by Messrs.
Fourcroy and Vauquelin, who obtained it in treating
muscular flesh with nitric acid. They have de-
scribéd it as a new acid formed by the action of
nitric acid on the muscular fibre, and to which from
its colour they have given the name of yellow acid.

and it is partìy soluble in acctate of potass and of
soda. The French chemists found that if treated
with a fresh quantity of nitrìc acid, it acquires the
property of burning with the satne phenomena as a
combustible body mixed with nitre. This fact iSù^^y
consìdered as remarkable, since they could not de-
tect any nitric acid in the yellow acid. But the
latter, as will be presently shewn, is nothing more
than a combination of fibrin with nitric acid, (oriu
other cases, perhaps, with nitrous acid,) and also
with another acid formed by the decomposition df
a portion of the fibrin, a species of combination
very analogous to the one already described. If
the yellow substance be boiled with alcohol, a yel-
low adipocirous matter is takeh up ; but it is depo-
si ted when the liquor cools. This sebaceous matter
has a great resemblance to that obtained by the
action of alcohol on pure fibrin. If the yellow sub-
stance, after being thus deprived of its adipocirous
portion, be digested with water and carbonate of
lime, it slowly decomposes the carbonate, disen-
gages its acid in the form of gas, and produces a
yellow solution. Having séparated this fluid fìrom
the undissolved portion of the yellow substance, I
concentrated it to the consistence of a sjrrup : and
then poured in alcohol, which precipitated one
part, retaining the other in solution. The precipi-
tate had ali the characters of malate of lime. Dis«
solved in water, and decomposed by a sufficient
quantity of sulphuric acid, it yielded sulphate of
Urne; and the acid liquor being filteréd and evapo-
SÌOS ^ CHEMICAL PROFERTlES
rated, gave a brownish and liighiy acid i^fup^
possessing aH the properties of malie acid. The
portion dissolved in the alcohol was evidently a
mixture of nitrate and nitrite of lime. The mixture
consisting of undecoraposed carbonate of lime, and
tlie insoluble part of the yellow substance, beìng
decomposed by diluted muriatic acid, left a yellow
mass perfectly sìmilar to the one which I had before
decomposed, and possessing, like that substance,
the property of reddening litmus paper. It appear-
ed therefore that I had merely exchanged the ni-
tric and malie, for tlie mmiatic acid.
We thus find that fibrin enters into combination as
readily with nitric acid, as with the other beforemetì-
tioned acids, and that it is capable of forming two
combinations, the one containing an excess of acid
and having a pale yellow colour, the other neutral
and of an orange bue. By digesting fibrin with
nitric acid, it undergoes a species of decomposition
by which malie acid is formed. This acid in con-
junction with the nitric acid combines with the im-
decomposed fibrin. The fibrin thus united with
the two acids is certainly in some degree altered,
for its neutral combination with nitric acid is inso-
luble in Vater, and retains its insolubili ty and its
yellow colour even when the nitric acid has been
displaced by muriatic. On the other band, we
bave seen that the precipitate thrown down by ni-
tric acid firom a solution of fibrin in acetic acid,
acquires a yellow tinge, but that watei^in depriving

it of the excess of acid, renders ìt gelatinous and
again soluble. It follows that the fibrin, which, in
the yellow body, performs the office of a saline base
to the nitrìc acid, must be modifìed in a difTerent
manner from what it is in fibrin combined witli the
acids in the soluble combinations.
The nitric acid, in which the yellow substance
has been formed, has a bright yellow colour : it
holds in solution a portion of the yellow substance
with a quantity of malie acid, Mixed with alkali
in excess, it assumes a very dark yeUowish brown
coloun
7. In caustìc alkalij fibrin increases in bulk, be-
comes transparent and gelatinous, and at length is
completely dissolved. The solution is yellow with
a shade of green. Acids occasion in it a precipitate
which gradually becomes confluent. The solution
of fibrin in caustic alkali is precipitated by alcohol^
which by means of the excess of alkali dissolves a
portion of the neutral combination of fibrin with
alkali. If the aqueous alkaline solution be evaporat-
ed, a coagulum is formed towards tbe end of the
process, probablyin proportion as the alkali becomes
carbonated. The action of alkali upon fibriu pro-
duces some alteration in its properties, fot th^

dissolve by an additional quantity of acid. But
whatever be the nature of this change induced oa

converted, as M. Fourcroy has alleged, into a fatty
substance with which the alkali produces a sapona-
ceous compound, nor has it even the least analogy
to any species of soap. As far as I can perceive,
tìiis effect of alkalies is confined to the epidennoid
textures, and parts which by long arid continued
boiling are converted into a simìlar substance.
s
Ofihe Colùuring Matter and its Chemical Properties.
In order to separate, as much as possìble, the
colourìng matter from the albumeft and the salts of
serum, I cut the crassamentum irito very thin slices
which I placed upon blotting paper, till it had
taken up ali that it could absorb : after which they
were dried. A portion of the crassamentum treat-
cd in that manner, was triturated with water as
long as it appeared capable of acting as a solvent.
Tliis water acquired from the matter it had dissolv-
ed, a brown colóur of so deep a shade that ìt did not
exhibit the least transparency when contained in a
glass tube of a quarter of an inch in diameter.
The fluid had a faint odour of blood, and a mawkish,
saline and highly nauseous taste.
I coagulated the solution by raeans of beat in a
pneumatic apparatus. The mass frothed consider-
ably, but no elastic fluid was disengaged. While
yet hot, it was placed on a Alter : the liquor had a
tea colour which it lost by cooling, arid at the same
lime deposited a small quantity of the colouring
matter. I shall revert to this liquor in the sequel.
OF ANIMAL FLUID9. 209
The dark brown coagulated matter» after being
tarefully washed, and subjected to a powerfìil press^
was drìed at a temperature of TO'" (centigrade ther*
mometer.) It was but little contracted by the ex-
siccatìoii, but had become black^ hard, difficultly
palverisable. and shewed a vitrous fracture. Before
the desiccation is complete, it is of a dark brown
colour, faas little cohesion, and forms a granulated
mass: drcumstances by which it may be distin.
guished from both fibrin and albumen.
1. The colourìng matter is acted upon by hoiling
'water in nearly the same way as fibrin, becoming
somewhat contracted by coction; and the solution
contains soda, and an animai matter perfectly ana- .
logous to that wliich k obtained from fibrin^ but
rather less in quantity: for it would appear that a
, portion of this sabstance begins to be fbrnìed from
the comibencement of the process of coagulation.
It retains its black colour, but loses the property
of softening, and dissolvìng in acetic acid.
2. Alcohol and etìher convert the colourìng mat-
ter in part, into a &tty adipocirous mass, having a
very disagreeable odour.
3. In acetic aeìd^ the colourìng matter immedi»
ately becomes soft, forming a black and tremulous
jelly, which dissolves ia tepid water with the disen-
gagement of a small quantity of azotic gas. The
solution is reddish brown and only sémi-traixsparent»

210 CUEMICAL PaOPJERTIES
A small part of the coloUriog matter remains un-
dis$olvedt aud forms with the acid a compound of
very sparing solubility.
A solution of the colouring matter mixed witl»
^cetic acid does.not coagulate; hut when made to
boil turns black and deposits a very small quantity
of its insoluble compound, without however coagu-
lating. .
Tlie solution of the colouring matter in acetic
acid is precipitated both by alkalies aud by alkaline
prussiates. Ammonia produces a dark brown pre-
cipitate, which when well washed and weighed, is
found to be the colouring matter unaltered, and
àgain soluble in acetic acid. The solution after
precipitation by ammonia is. yellow, and deposits by
evaporation a quantity of white matter, which ìi
readily distinguished to be albumén, of whioh it is
impossible entirely to deprive the crassamentum.
Prussiate of ammonia precipitates from the acetic
solution a mass of a blackish brown colour, resem-
bling the precipitate by pure ammonia. Both ihese
precipitates, employed as pigments, give the stme
shade of a dirty brown. The prussic acid, therefore,
appears to exert no action on the colouring matter
of the blood; which should take place if the latter
owed.its colour to a ferruginòus «alt. The solution
of colouring matter in acetic acid is precipitated by
the mineraL acids, and the precipitates have-pre*

4. Concentrated muriatic acid does not dissolve
the colouring matter, evén when aided by digestion :
a small quantity of azotic gas is disengaged and the
acid assumes a yellow tint : alkalies, however, prò--
duce in it hardly any precipitate. The undissolved
portion is a compound with excess of acid which
becomes soluble in proportion as the superabund-
ant acid is carried oiR The neutra! solution of co-
louring matter is brown, and has the sàme properties
as that formed by acetic acid. The colouring mat«>
ter boiled for a long time with muriatic acid, suffers
a commencement of dacomposition ; some iron is
taken up by the acid, and the undissolved portion
is no longer soluble even by repeated washing, al-»
though in this state it retains a portion of acid, of
which the water cannot deprive it*
5. The nitricacid produces the same effects in
the colouring matter as on fibrin; the only dis-
tinctìon being in the colour, which in the formey
is invariably black,

ter assuming a very deep brown colour. A pre-
cipitate is thrown down by acids, but not by the
alkaline prussiates. The precipitate formed by

212 CHEMICAL PROPERTIES
acetic acid is again soluble, but only by an excess
of acid.
7. In solution of caustìc Jixed alkali the colour-
ing matter is softened, forming a browni^ jeBy>
which is dissolved by a sufficient quantity of water.
During the evaporation it coagulate» in próportion
as the alkali absorbs carbonic acid. The alkaline
solution Ì3 precipitated by alcohol, which, however,
acquìres a red tihge by dissolving a small quantity
of the compound fbrmed of the colouring matter
with the excess of alkali. The alkaline solution of
colouring matter seen by day-light has a green
colouF, buf appears red by candle-Ught. It was
npon tbis appearance of gteen that Fourcroy con-
ceived the idea that bile might be formed by boil-
ing blood with a small quantity of water ; but thia
green fluid, as we shall afterwards see, agrees with
bile in no property excepting colour.
8. If a solution of the colouring matter in water
be exposed to a beat of 5(f (centigrade thermome-
ter) in a saucer, it blackens aiid dries completely
without coagulating. In this state it is again en-
tirely soluble in cold water.

one another principally by a difference in colour; by
the fibrin coagulating spontaneously in ali tempera-
tures, while the colouring matter nmy be dried,
without losing its solubility in water, and becomes
insoluble only at a certain temperature : and lastly
by the peculiar character of the latter when coagu-
lated, such as its not being diminished in volume
during the exsiccation, as happens with fibrin.
Inquiry info the ÌTifltience of the iron containcd in the
colouring matter^ in prdducing its colour.
The greatest chemical difference that is found be-
tweenfibrin, albumen, aridcolouring matter, consista
in a quantity of oxide of iron being contained in the
ashes of the colouring matter, while none, or at '
least an infinitely small portion is af&rded by the
others. Parmentier and Deyeux, to whom we are
indebted for an elaborate memoir on the blood,
,have conjectured that the iron, contained in the
blood, was dissolved in a way analogous to the al-
kaline tincture of Stahl, an opinion which has since
been controverted by Fourcroy and Vauquelin,
who, on their side, bave endeavoured to prove
that the colouring matter of the blood was a solu-
tion of red subphosphate of iron in albumen. We
shall find that neither of these theories can be true,
and that the t^ode in which the iron is cambined
with the colouring matter will probably long re*
main ynknown.
214 CHEMICAL PROPERTIÈS
The colouring matter dried, and exposed to lire
in an open crucìble, melts and swells up, and at
last burns with flame. It leaves behind a poroiis
coal, which cannot be incìnerated without the
greatest difficulty* For this purpose it must be re-
duced to a very fine powder, and exposed to the
fire in very thin layers. Whìle the charcoal is con-
suming, it continually exhales a smeli òf carbo-
nate of ammonia, which proves that the constitu-
ents of ammonia are not disengàged from the char-
coal by heàt alone^ but that the influence of 0x7.
gen is also required in ord^r to effect the separa-
tion. The ashes remaining after the destruction of
the carbon is yellow and pulverulent.
The disetìgagement of ammonia from a mass of
burning charcoal which has already been exposed
for a long time to fire, is undoubtedly a very re-
markable phenomenon; but another and a no less
singular fact is presented by the same substancè.
If the cl^rcoal which has already been long burti-
ing, and whose surface is covered with yellow
ashes, be pulverised and boiled in nitro-muriatic
acid, the acid dissolves the ashes already fofmed,
but does not deprive the remainder of the charcoal
of the property of affording a fresh quantity of ashes
on re-exposure to the fire. These observatipns
seem to prove that the carbonaceou* matter of the
colouring substancè which remains after the flame
has ceased to appear, and after the whole mass has

been subjected to a strong red beat, cannot be, as
was before supposed, a mechanical mixture of char-,
coal with the phosphates and carbonates of the
earths and of iron. We must therefore consider it
as a chemical compound of carbon, phjpsphonis,
sulphur, with calcium, ammonium^ and iron ; and
it appears that it is in a mode analogous to this com-
bination that the iron as well as the calcium, phos-
phorus &c. are united with the charcoal, and other
constituents of the colouring matter ; for it is very
evident that the mode in which combustible bodies
*
combine with one another, and with a small portion
of oxygen in organic substances, is totally different

ductiòns of naturet
To return to the ashes of the colouring matter ;

roixed with muriate of soda. I bave great reason
jto suspect that these two constituents are merely
accidentale and that tliey appear in consequence of
the impossibility bf freeing the crassamentum en-
tirely from serum. If the alkaline liquor which is
obtained from the ashes, be saturated by acetic
acid, evaporat^d to dryness, and again dissolved, a
precipitate will appear on the addition of lime-w^-
ter, which is phosphate of lime, but in so minuta a
. quantity as npt to be appreciable,

But this phosphate of iron was not, in ali proba-
bility, contained in the colouring matter, not even
in the ashes: it has evidently been a produet of the
analytic process. It is produced in iike manner
when oxide of iron and phosphate of lime are dis-
solvedtogetber in an acid, and aflerwards precipitata
^d with caustic ammonia. Part of the lime x^
mains in solution, and the iron seizes upon its phos-
phoric acid.
But as one mode of argument will hardly suffice
to overtum a theory maintained by chemists of such
pminence as Fourcroy and Vauqudin, and for
the support of which they bave brougfat forward
many positive facts, I bave made a number of ex-
perimentsi with a view of throwing light on this
subject, and bave not ^let with a single one, which
^idnot appear in contradiotion to the opinion of
these celebrateci analysts« Some of these experi-
ments I shall now relate.
(A.) The prussiates, as we have already secn,
produce no effect on the colouring matter of the
blood ; and yet they detect, after 24 hours, the
least quantìty of any ferrugineous salt added te it^
bavìng the red oxide of iron for its basìs.
(B.) A watery solution of colouring matter^ mixed
with gallic acid^ acquires a beautiful red colour,
but the acid produces no precipitate. By adding
to the solution of colouring matter one or two drops
of a dilute solution of tannin, the liquor becomes
•of a beautiful red, without any precipitate appear-
ing. But if on the contrary, tlie solution of tan-
nin be concentrated^ it precipitates tlic colouring
matter, and gives it a pale red colour. None of
ihese effects seem to prove the presence of a salt
,with tlie base of oxide of iron.
(C.) The aqueous solution of colouring matter,
mixed with solution of bary tes, is not precipitated :
t^t the end of 24 hours a sinall quantityof phasphate
of barytes is found at the bottom of the vessel, and
the liquor has assumed a green colour by the action
of the alkaline base. Lime water produces no
change.
(D.) A solution of gulphuret of potash produces
QO change in the solution of colouring matter, ex-

cept that the red colour is slowly converted ìnto
green by the action of the alkali. A drop of ace-
tic acid precipitates the sulphur of a white colour.
(E.) It is well known that none of the minerai
acids deprive the colouring matter of its colour,
which ought to be the case if that colour had been
owing to the presence of the subphosphate of
iron* The phosphoric acid mixed with the co-
louring matter blackens without precipitating it :
whereas, if the opinion of the French cbemists
were correct, it ought to produce a neutral and
colourless phosphatCt
(F.) A drop of a solution of acetate of lead ex-
alts the colour of the colouring matter, and a larger
quantity throws dowji a fine red precipitate,
(G.) The nitrates of &ilver, of lead, and of mer-
cury blacken the colouring matter, and wben addi-
ed in larger quantity precipitate it,
«
These experiments prove that the iron in the co-
louring matter is not contained in it in such a way
as to admit of being detected by the best re-agents
we possess, until the composition of the colouring
matter is totally destroyed.
But how can these facts be reconciled with the
following, mentioned by Fourcroy in bis Systéìnedes
Connoissances Cht/miques? " Vauquelin and I,'* says
1
ÒF ANIMAL TLtJIDS. 219
he, " bave found that the subphosphate of oxide of
iron is easily dissolved in albumen by a slight agita*
tion and without the aid of beat, and that this so-
lution possesses a bright red colour, similar to that
of the blood. This colour becomes stili more vivid
by adding a little caustic alkali, which fàcilitates
stili mòre the solution of the subphosphate in albu-
men."
It was not till after having made and carefuUy re-
peated many experiments, that I could venture to
pronounce this opinion to be void of foundatiom
I shall not seek to form any conjectxu'e with regard
to the circumstances which may bave deceived
thesG distinguishedchemists, but shall merely relate
my own experiments on the subject*
The subphosphate in question, newly prepared
and stili moist, easily mixes with serum, giving it
the colour of rust ; but it subsides in process of
lime, and may be entirely separated from it by
means of a fìlten The neutral phosphate of oxide
of iron, mixed with serum also, does not dissolve^
and the addition of caustic- alkali instantly prò»
duces the subphosphate ; but this last remains un-
dissolved, and communicates to the liquor a colour
of rust, which is quite dissimilar to that of the co-
louring matter of blood. The serum deprived of
subphosphate by filtration retains a pale yellowish
colour, which is owing to a small quantity of oxide
i>f iron hcld in solution.
220 CHEMICAL PROFERTIES
If serum is mixed with the sub^phosphate in
question, and phosphoric acid is added, so as la
dissolve the subphosphate, a clear rust-coloured
liquor is formed, from which a small addition of
caustic alkali precipitates a little albumen, which
is again dissolved by a slight excess of the alkali ;
and then the solution loses its rcd colour, and the
subphosphate falls down, and may be coUected on
thè fìlter.
In ali these experiments the albumen dissolyes
the oxide of iron, even in greater quantity than
exists in the colourìng matter of the blood ; but
this solution is yellowish, and has but little body
of colour ; and the oxide of iron is shewn by the *
usuai reagents* The albumen of serum wiU also
dissolve many other metallic oxides, for instance,
that of copper, as Vauquelin has long since proved;
and it is doubtless the albumen which is the men-
struum of the oxide of mercury, found dissolved in
the blood during a course of this metal for the cure
of syphilis. The oxidulum (or black oxide) dis-
solves easily, and stili more copiously, in serum,
forming a perfectly limpid sea-green liquor. The
solution is readily obtained by adding to serum
some salt c^ irOn, which has the black oxide for ita
base, and neutralizing its acid by an alkali. When
this green solution is exposed to the air, it ahsorbs
oxygen, deposits red oxide of iron, and becomes
yellow. The compounds of oxide of iron Imd aU
bumen are dccomposed by the minerai acids, which
OF ANIMAL FLUIDS. 221
precipitate the albumen colourless, and retain the
iron in solution. The prussiates alone do not dis-
turb the solution of iron in albumen, because the
metallie oxìde is not bere dissolved by any acid ;
but if, àÀer mixing them, a little muriatic acid is
added, an exquisitely beautiful azure blue precipi-
tate appears, consisting of albumen and Prussian
blue. If the acid phosphate of iron is dissolved
in acetic acid, and afterwards serum be added, fol-
lowed by a little caustic alkali, the albumen and
subphosphate are precipitated together, of a rust-
colour, which is not changed by drying, but has
no resemblance to the colouring matter of blood.
In a word, I have not been able to find any me-
thod of combìning albumen with subphosphate of
iron^ or with any other salt of this metal, so as to
produce a compound identica! with the coloiuing
matter of the blood.
But firom the result of aU these experiments,
what appears to be the difference betweeH venous
and arterial blood ? This question I am unable to
answer; nor can I explain the difierence between
diese substances befbre and after coagulation.
I have already mentioned that the liquid out of
which the colouring matter has been coagulated by
beat, has at first a tint of red, which it loses by
cooling ; at which time it further deposita a small
quantity ^f colouring matter. This liquid, whilst
evaporating, becomes green, owing to the actiou
2
282 CHEMICAL phoperties
of the uncombined alkali on the small portioti of
colouring matter that it stili retains. This liqukl
holds also in solution ali the salts, and the so-
luble animai substances belonging to that portion
of the semm which stili adheres to the coagulum,
and cannot be entirely separated from it. The coa-
gulum, I bave found by one analysis, Ito consist
(exclusive of the saline and uncoagulable ingre-
dients) of 64 parts of colouring matter, and 36
parts of an insoluble mixture of fibrin and albumen.
Ofthe Seruniy Albumen, and Salts ofthe Bhod.
When serum is heated in a glass vessel, over a
water-bath, it solidifies and forms a pearl-coloured
jelly, transparent at the edges. If it is stirred the
coagulation is more unijfbrm. It has been said to
blacken any silver instrument employed to stir it ;
but this only happens when the serum has begun
to putrefy, or when the bottom of the coagialum
has been bxumt. As this blackening of silvef is
owing to sulphur, this substance has also been
reckoned among the constituent parts of blood.
But it would be equalìy proper to consider carbon
and hydrogen as constituent parts, since these en.
ter into the ccÉnposition of albumen, in the same
way as sulphur does*
jSIuriatic acid coagulates serum. ^lien heated,
a small quanti ty of azotic gas is evolved. This
coagulum has exactly the same propertiés as the
qpmpound of fibrin and muriatic acid«
OF ANIMAL FLUIDS. fi2S.
The sulphuric and nitric acids also produce witìi
the albumen of serum precisely the same com-
pounds as with fibrin.
Phosphorìc acid does not coagulate serum.
The acetic acid does not coagulate serum, and
when thìs acid is in sufficient quantity, it prevents
the coagulation on heating.
In short, the albumen of serum produces ex-
actly the same compounds with. acids and alkalies
as the fibrin does, and therefore to avoid repeti-
tion, I shall refer the reader back to my observa-
tions on this latter substance. Tlie action of al-
cohol also is perfectly similar in both cases.
There appears therefore to be very little differ-
ance between fibrin and albumen ; and the latter
seeips to be intermediate between fibrin and the co-
louring matter. The only character of distinction
between fibrin and albumen is, that albumen does
not coagulate spontaneously, but requires a higher
temperature for that purpose. Coagulated albu-
men does indeed dissolve more slowly than fibrin
or colouring matter in acetic acid and in ammonia,
but probably this is owing to the influence of the
heat employed for its coagulation.

the French chemìstshave examined this acid ; and Fourcroy^ Vau-
qudin^ Thenard, and Bouillon La Grange, have sought to prove
that Scbeele was niistaken in the supposed peculiar nature of this
acid, and thàt ìt is only a combination of acetous acid, with some
animai matter.
These cfaemists, howerer, have made no attempts to obtain this
animai matter separate from the acid, and have never succeeded
in producing the lactic acid by means of the acetic ; but this is
the proof which they ^ve of Scbeele being in an error. Lactic
acid ìs combined with an alkali, the resulting lactate ìs distilled
with concentrated sulphuric acid, and in the recdver is obtained
a mixttire of sulphureous, muriatic, and empyreumatic acetie
acid, the latter of which is purified, and hence it is, that we are
informed that the pretended lactic acid is only the acetous united
with some animai matter. But it appears to me, that the French
chemists have only cut the Gordìan knot ; for one of the proper-
ties of the lactic acid, is to be incapable of volatilization, and it
is a property of the sulphuric acid to change many organic sub*
, stances with which it is distilled, into the empyreumatic ace*
tous and sulphureous acids. By a parity of reasoning, almost
every one of the freed vegeiable acids might be proved to be only
acetic acid, combined with some matter which deprives it of ite
volatility, without destroying its other acid properties; and in
fact it is thus, that Bouillon La Grange has inferred that the malie
and gallic acids are only varieties of the acetic. In an analysis
of muscular flesh, which I made in the year 1806, I found that
the humours of the muscles contained a free acid, which, by
many experiments^ I discovered to have ali the properties which

ed> that two acids that produce saUne compounds di^reat fìrom
each otbery cannot be identi^eal in their nature^ the distination be^
tween the lactic and the acetic acids cannot be controverted. It
i& since that time that I bave discovered the lactic addy free or

Many chemists bave obserred^ in their analysis of animai fluids*
that the alcoholic solution when evaporated leaves a yellow, deli*'

to this extract, and if I mistake not, it has been considered as a
single substance, and has reeeived the name of osmazome, One
of the component pafts of this cxtract is lactate of stoda, and the
other, with which it is intìmately eombined, is an animai matter
that may be separated by means of tannin. To prove the pre^
sence of lactic acid> dissolve the whole in alcohol, and add a mixture
of sulphuric acid much diluted with alcohol, as long as there ap-

deal of the residiiary uncoagulable fluid. This I
mixed with barytic water, which after a time gave a
felight precipitate, soluble in muriatic acid. Some
of the same serum, mixed with lime-water, was
not clouded. It follòws from this, that the blood
contains no sulphuric acid, and only a véstige of
the phosphòric. In my Trèatisé on Animai Che-

I washed the albumen well in this experiment,
digested it in muriatic acid, and then burnt it to
ashes, which were almost exacdy equal in qìuantity
tq the ashes produced by the combustion of the
same weight of colouring matter, But the ash of
the albumen was white, and did not shew a parti-
eie of iron. I found a trace of soda, but the
greatest part was phosphate and carbonate of lime,
with a little magnesia. It is clear, therefore, that
the earthy salts found in the aJshes of coloured
blood had not been dìssolved in the blood, nor
even existed as salts in the blood, from whìdh they
were obtained by means of combustion. Hence
we may conceive, how the blood can produce and
deposit in the animai economy, the earthy pho»-
phates, which, however, are not soluble either in
pure water, or in the blood; and hence too we

Ali the authors who have written on the blood^
assert that gelatine is one of its component parts*
This, however, is a mistake, and arises from the
gelatinous appearance of the albumen, as I have
never been able to detect a partìcle of gelatine in
blood ; and, as far as my researches extend, I
have found gelatine to be a substance altogether
unknown to the economy of the Hving body, and
to be produced by the action of boiling water on
cartilage, skin, and cellular membrane, substances
which are totally distinct from fibrin and albumen.
On Human Blood.
The blood of man perfectly resembles in com-
position that of the ox, but the coagulum of hu-
man blood is more easily décomposed by water,
and the fibrin thus obtained is more transparent,.
When dried, it amounts to no more than 0.75 from
lOCX). parts. Human fibrin has the same chemi-
cai properties with that of the ox, but is more
readily incinerated : the white ash coilsists of the
phosphates of lime and magnesia, a little carbonate
of lime, and soda»
The colouring matter of human blood is also
chemically the same with that of ox blood, but is
much more easily reducible by fire to the same
yellow ash, which seems to shew that it contains

precipitate of phosphate of barytes, soluble in an

Human albumen is more easily incinerated than
that of the ox, and contains more soda and phos-
phate of soda. A hundred parts of the dried al-
bumen give twelve parts of calcined ash.
The muriates found in human blood are triple
the quantity of those in ox blood, owing doubtless
to the salt consumed by man in his food. Human
blood also contains a larger proportion of muriate
of potash,
On the whole, the great agreement in the com-
position of human and of ox blood is remarkable,
and explains to us the possibility of the phenomena
obseryed in the experiments in transfusion.

S. The portion which is suspended is the colour^
ing matter. It differs from the albumen chiefly in
its colour, and its insolubility in serum. The co-
lour seems to be owing to iron, of which it con-
tains j per cent of its weight, but which cannot
be separated from it as long as it continues to be
colouring matter. This separation can only be af-
fected by combustion, or by the concentrated acids,
both of which agents entirely decompose the sub-
stance with which the metal was combined. The
colouring matter cannot be artificially produced by
uniting albumen with red sub-phosphate of iron.

Scrum absorbs very little oxygen, and only in proportion as it is
decomposed. Can the iron in the colouring matter give it this
property ? This is probable ; but we shall never arrive at any ac-
curate knowledge of these phenomena, without first analyzing

unite with acids, and produce compounds, that
may be termed saline ; these, when neutralized,

excess of acid. The acetous and phosphoric acids

of these forms a compound soluble in water. Ni-
tric acid, digested with the albuminous contents,
forms an insoluble compound consisting of the al-
bumen in an altered state, and of the nitric and
the malie acids. This property of combining with
àcids, is retained in some instances by the albumen
after it has updergone the changes produced in the
secretory organs ; as for instance in the peculiar
matter of the bile, the curd of milk, &c.

234 CHEMICAL PROPERTIES
Secreted Fluìds.
There exists no problem in chemistry more dlf^
ficult to solve, than that of the secretion of ani.,
mal iìuids. The circulating fluid is carried to the
organized laboratory which nature employs, no fo»
reign ingredient is added, no chemical reagent is 1
interposed, and yet the fluid which flows from these
organs has acquired chemical properties, which
render it decidedly different from the common cir-
culating mass. Not only is the chemical agent
which produces these changes unknown to us, but
we shall in vain search for any analogous chemical
operation. It is doubtless easy tp conjecture, that
it is by the influence of the nervous system, thì^t
this decomposition of blood into the secreted fluids
is effected ; but what is this influence ? If elec-^
trio, how can it be brought to record with our pre-»
sent knowledge of electric agency ? But avoiding
vain conjectures on a subject which perhaps will
ever remain a mystery, let us determine from
the knowledge we already possess, th^ chemical
nature of the materials of their products. In prò-
portion as we acquire light pn the nature pf the
former, the analysis of the latter becomes more
and more interesting,, and much may be done by a,
judicious comparison of the one with the othen
There are two classes of secreted fluids ; name^
ly, the secretionSj properly so called, or the fluids
intended to fulfil some ulterior pqrpose in the ftni-»

mal economy; and the excretions vfhìch are directiy
4ispharged from the body. The fluids 9f the former
class are ali alkaline ; and of the lattei, ali acid. The
excretions are the urine, the perspired fluid, and
the milk. Ali the other fluids appear to belong to
the former class.
•
The alkaline secreted fluids may be divided into
two very distinct species. The former of these con-
t^ins the same quantity of water as th^ blood, so
that the change induced by the nervous influence,
seems to be confined to that of altering the chemi-
cal form of the albuminous materials, without af-
fecting their relative proportion to the water ànd
Dther substances dissolved in the blood. The bile>
$permatic fluid, &c. are of this kind. The latter
species consists of fluids in which the influence of
the nervous system has separated a large portion of
the albuminous matter, and left the remainìng liquid
proportionally more watery. The saliva, the hu-
jnors of the eye, and the efiused serum of mem-
branes are of this species; and in these the quanti-
ty of salts, and in general alsp of alkali, is the same
3,s in the blood*
The influence of the chemical agent of secretion
is therefore chiefly spent upon the albuminous ma-
terials of the blood, which seems to be the source
of every substance that peculiarly characterizes each
secretion, each of which is sui generis^ and is its
|9rincÌLpal constituent. Ali the other parts of the
SS6 CHEMICAL PROPERTIES
«ecretion seém to be rather accidentale and to be
found there only because they were contained in
the blóod out of which the secretion was fbrmed.
Therefore in examining the secreted fluids the
chief attention should be paid to the peculiar mat-
ter of the fluid, which varies in alL This matter
sometimes retains some of- the properties of albu-
jnen, at other times, none ; and hence an accurate
analysis shewing the quantity and nature of this pe-
culiar matter is above ali to be desired.
If the several secretions be supposed to be de-
prived of their peculiar matter, and the remainder*
analyzed, the same residue would be found from
them ali, which also would be identical with the
fluid separated from the serum after its coagulation.
Thus we should find, first, a portion soluble in al-
cohol, consisting, as has been already shewn, of .
the murìates of potash and soda, of lactate of soda,
and of an extractive animai substance precipitable
by tannin: and secondly, of a portion soluble only
in water, containing soda (which acquìres carbonio
acid by evaporation, and is separable by acetic acid
and alcohol) and another animai substance, not ex-
tract, precipitable from its solution in cold water
both by tannin and by muriate of mercury. Some- .
times a vestige of phosphate of soda will also be de^
tected.
The excretions are of a more compound nature.

OF ANIMAL FLUIDS. 2S7
They ali cantain a free acid, which is the lactìc^
and in the urine this is mixed with the urie acid.
Urine seems to contain only a single peculiar cha-
racteristic matter ; but milk has as many as three,
namely, butter, curd, and sugar of milk, which^
however, seem to be produced by difFerent organs
that mingle their fluids in the same receptacle*
The perspired fluid appears to bave no peculiar
matter, bùt to be a very watery lìquid with hardly
a vestige of the albumen of the blood, and, in short,
is the same as the other excretory fluids would be
when deprived of their peculiar matter, If we sup-
pose this matter taken away from those excretions
that possess it, the remaining fluid wiU be found to
bave properties very different from the fluid part of
the secretions, when equally freed from their pe-
culiar matten That of the excretions is acid, con-
tains earthy phosphates, and when evaporated,
leaves a much larger residue than the fluid of the
•secretions, This residue is yellowish-brown, of
the consistence of syrup, with an unpleasant sharp
saline taste of the salts that it contains. It reddens
litmus, is mostly soluble in alcohol, and this spu
rituous solution contains the murìates of the blood
together with free lactic acid, much làctate of soda
(the soda being the free alkaU of the blood neu-*
tralized by this acid) and the extractive matter
which always accompanies this neutral salt. The
part insoluble in alcohol contains a distinguishable
quantity of phosphate of soda, a little of a similar
animai matter to that found in the secretions, and

matter and any of the minerai acids often forms
with the same oxides a substance lìke a plaster, re»
sembUng in this respect also the true resins.
m
The degree of insolubility possessed by these
compounds of acid and biliary albumen varies both
according to the species of animals, and also accord-
ing to the length of time that the bile has bcen
extracted; for the longer it has been kept, the
more solubility these compounds acquire j but in
this case I bave always found that by pouring in a
fresh quantity of acid, and slowly evaporating the
mixture, the resinous matter falls down as the su-
pematant liquor becomes more acid.
The biliary matter may be obtaìned pure in the
following way: ,mix fresh bile with sulphuric acid
diluted with S or 4 times its weight of water; a
yellow precipitate of a peculiar nature first appears,
which must be allowed to subside and be removedj
then continue to add fresh acid as long as any pre-
cipitate is formed; beat the mixture gently for
•somehours, andafterwardsdecant the fiuidpart, and
thoroughly edulcorate the green resin which is left.
This resin reddens litmus, and is partially and spar-
ingly soluble in water. It may be deprived of its
acid in two ways: one of them is by digesting it
with carbonate of barytes and water, whereby th«
carbonate is decomposed, and the water forms a
green solution possessing aU the peculiar charactera
of bile: the otìier way is by dissolving it in alcohol
OF ANIMAL FLUIDS. 241
ànd digesting the solution, either with carbonate of
potassor carbonate of lime tillit no longer reddens
litmus, and then evaporating it to dryness. Either
of these methods wiU give the pure biliary matter,
and there are also other ways of obtaining it, which
I bave described in my work on Animai Chemistry,
Voi. II. p. 47.
This peculiar biliary matter when pure, resembles
exactly entire desiccated bile. Being soluble in al-
cohol it might be supposed that it would dissolve
in ether, but this is not the case, for ether only
changes it tp a yery fetid adipocirous substance,
exactly as it acts upon the albuminous matter of
the bloodé One circumstance relating to the biliary
matter has much surprised me, which is, that it
gives no ammonia by destructive distillation. There-
fore it contains no azote ; but what can bave be-
come of the azote of the albuminous matter of
the blood ? for, no vestige of azote is found in any
other of the constituent parts of the bile, nor does
^ bile contain any ammonia.

The saliva is one of the fluid secretions which

discharged from the mouth it holds suspended a
tnucus which is not dissolved in the saliva, but

subsides fì*om the saliva when kept in a cylindrical

which remains ih the insoluble portion is then ex-,
tracted by fresh spirits slightly acidulated with acet-
ous acid. The resìdue is mucus mixed with the
peculiar salivary 'matter, which last may be dissolv*
ed by water, leaving behind the insoluble mucus.

This peculiar matter is therefore soluble in water
but not in spirits of wine. The solution in i^ater,,
when evaporateci to diyness, leaves a transpar^nt
mass that easily again dissolves in cold water. This
solution is mot precipitated either by alkalies, or
acìds, or subacetate of lead, or muriate of mercu-
ry, or taiinin ; neither does it become turbid by
boiling.
The nmcus of the saliva is readily procured by
mixing saliva with ^distiUed water, from which the
mucus gradually subsides, and it may then be col-
lected on the filter and washed. In this state it is
white, and would seem to contain phosphate of lime
ini:sed with it. This mucus is quite insoluUe in
water ; it becomes transparent and horny in the
acetic, sulphuric, and muriatic acids, but does
not dissolve in them, and the alkalies separate no-
thing from them. The mucus therefore contains
no earthy phosphate, though its appearance would
lead tó suspect this earthy salt. It dissolves in
caustic alkali, and is again separated from it by the
acids. A small proportion escapes the action of
the alkali, but yièlds to muriatic acid, and is not
separable from this acid by an excess of alkali.
Tlie mucus of the saliva is very easily incinerated,
and though no phosphate of lime is detected in it
by the acids in its naturai state, a considerable por-

Is this mucus secreted in the saKvary glands, or
is it only the common mucus of the mouth ? The
Jatter appears most probable, though I confess that
the large quantity of this mucus contained in the
saliva, and the great diiFerence between its chemical
properties and those of the nasal mucus, throw some
doubt on this opinion.
It is this mucus that produces the tartar of the
teeth, which at first is only mucus precipitated on
the surface of the teeth and adhering to them, but
soon it begins to decompose, its colour changes by
the influence of the air from white to yellow or
greenish, the warmth and moisture of the mouth
contribute to complete the decomposition, and the
same earthy phosphates which are produced by oxi-
dation and combustion in open fire are bere formed
and slowly deposited on the sur&ce of the tooth by
a slower but a similar process. The tartar is there-
fore as it were the ash of mucus cr)'stallized on
the tooth, and this, as is well known, will in length
of time form very large incrustations.

3» Tìte Mticus of the mticous membranes*^
I shall premise some remarks on the term mucics
as applied to animai chemistry. It properly signi-
fies the mucus of the nostrils, but many chemists
bave extended it to other substanees found in the
animai fluids, so tbat Jordan, Bostock, Haldat and
others reckon it among the constituents of these
fiuids. None of these chemists has considered mu-
cus, used asa general term, a» identical with the
nasal mucus, or, if they have thought so, it has been
a very great error. I must now mention that there
is no such principle as the mucus of animai fluida,
the substance so considered being in reality lactate
of soda mixed with the animai matter that always
accoBipanies it. But if it did exist as a separate
principle, some other term should have been used,
to dìstinguish it from the mucus of the nostrils
which is very different.
The chemists who bave the most attended
to the analysis of mucus, have been Messrs. Bos-
tock, Fourcroy, and Vauquelin, but none has
given a very satisfactory account of its properties^
The two latter chemists, who have published a
long memoir on animai mucus, bave too much
generalized the characters peculiar to nasal muco»,
in attempting to extend them to the mucus of the
intestines and gali bladder, &)t example, where
they are totally inapplicable.
The mucus of mucous membranes is- prodiiced
246 CHEMiCAt ^R0P£RtI£9
from tlje some secretory organ throughout the body,
and possesses every where the same external charac?
ters which constitute miicus ; but in chemical prp-
perties the mucus of different prgans varies ponr
siderably according to the required use in protect:
ing these organs from the contact of foreign subr
stances. Thus t|;^e mucus of the nostrils and tra^
chea» which is intended to protect these membrane^
from the external aix> differs from that pf the urin-
ary bladder which is to preserve this organ from the
contact of an acid liquor, or from that of the gall-
bladder whose contents are alkaline*
The anime! matter peculiar to mucus is the same
in ali cases, and has the following properties : it i$
insoluble in water^ but is able to imbibe so much of
t
this ifluid as to become more or less transparent^^
semi-Iiquid or what is termed glaiiy* If iij this
state it be laid on blotting paper, and the paper
changed as it becomes wet, the mucus ìnay be de-
prived of the greater part of the moisture which it
bad absorbed, and will then lose most of its pecu<-
Kar properties. Mucus is not coagulablq by boil-
ing, it becomes transparent when dry, atìd gene-
rally resumes its mucous cbaracter on adding fresb
water, but there is great difierence in thÌ3 property.

Nasal mucus when just secreted contains a great*
er proportion of wat^ than above stateci. It is
very fluid, and gives by evaporation pnly 0.25 per
cent, of solid matter. There is reason to suppose
that its peculiar animai matter is first dissolved in
the free alkaK, but is gradually precipitated as the
alkgli becoraes carbonated by the contact of the re-

has again lost nearly the whole of the moisture it
had imbibed. Mucus thus dried will again absorb
water when immersed in it, and resumé its trans-
parency j and tbis alternate wetting and drying may
be repeatedan indefinite numberoftimes^butitthus
gradually becomes yellowish and more resembling
pus. Five parts of recent mucus absorbed by 95
parts of water produce a glairy mass which will not
pour from a vesseL When mucus is boiled with
water it does not become horny, nor does it coagu-
late; the violent motion of ebuUition rends itin
pieces, but when the boiling is discontinued, it is
found coUected again at the T)ottoffl of the vessai,
and nearly as mucous as before. I should observe,
however, that this mucus naturally contains a little
albumen, which must first be extracted by cold wa^
ter to enable the remaining mucus to exhibit the
above mentioned appearances. The nasal mucous
matter dissolves in diluted sulphuric acid : when
the acid is concentrated, the mucus is carbonized.
Nitric acid at first coagulates it, a number of yellow
spots being dispersed through the coagulum ; but
by continuing the digestion it soflens and is finally
dissolved into a clear yellow liquid containing none
of that yellow substance which I bave described
under fibrin.
Acetous acid hardens mucous matter, but with-
out dissolving it, even in a boiling heat. Caustìc
alkali at first renders mucous matter more viscous,
and afterwards dissolves it into a limpid fiowing

liquìd. Tannin coagulates mucus both when soft-
«ned by the absorptìon of water, and when dis-
solved either in an acid or an alkali.
Thè mvcus of the Trachea^ as far as I bave been
able to examine, possesses the same properties with
the preceding. The first morning expectoration
often contains bluish or dark coloured flocculi,
which will imbibe 20 times their bulk of water, and
sometimes become thereby so perfectly transparent
as hardly to be distinguished in the surrounding wa-
ter. Acids and alkalies act upon them as on nasal
mucus.
The mucus of the GaJJMadder much resembles
that of the nostrils, but is more transparent, and is
always tinged yellow by the bile. When dried it
will again soften in water, but loses part of its mu-
cous property. Biliary mucus dissolves in alkali,
and its fluidity increases in proportion to the quan-
tity of the latter. If this solution is exactly saturated
with an acid, the mixture becomes slightly turbid
and of a consistence to be drawn out in threads.
Ali the acids produce with billiu-y mucus a yellow-
ish coagulum that reddens litmus. The coagulum
formed with the sulphuric acid may be restored to
its mucous properties by exact saturation with an
alkali. Alcohol coagulates this mucus into a very
yellow granular mass, to which the mucous property
cannot bp restored. A similar mass is often found
in the adipocirous biliary concretions, and it is re-
3
iSO CHEMICAL PROPERTIEg
markable that it may be produced from mucus by
alcohol, as from biliary matter by ether. ^
Bile itself is often of such a mucous cottsistence
as to be drawn out in threads. This is owing to
the presence of mucus dissolved in ihe alkali of the
bile. A very little of any acid (the acetous for ex-
^mple) precipitates the mucus, and destroys the vis-
cosity of the bile* Alcohol has the samel effect.
Former chemists seem to bave regarded this prò-»
perty of bile as owing to the presence of albumen,
the existence of which has been considered as de*
monstrated by the precipitate caused by addìng
acetic acid or alcohol. From what I bave already
mentioned, it is clear that no precipitate produced
by acetic acid can be albumen, since the lattei is
soluble in this acid; and as bile is not disturbed by
prussiate ofpotassorby tannin after the precipitate by
acetous acid is removed, this is a proof that no al*
bumen can be contained in bile. The foUowing ex-
periment is conclusive that the supposed albumen of
bile is only mucus: mix some bile with very weak
sulphuric acid, drain on a filter the yellow precipi-
tate thus formed, andthen digest itwith a saturating
quantity of carbonate of soda and water, and the
precipitate will be changed to a mucus which will
be more or less glairy according to the quantity of
water employed.

who, on txeating it with nitric acid, discovered in it
a peculiar muscular stnicture; and Mr. Chenevix

water is a suflScient proof that it is not a inuscle,
though to effect this solution it is necessary to
break it down, and then it leaves undissolved a
small portion of extremely pellucid membrane.
This circumstance, added to that of the increasing
density towards its center, shews that the structure

When bumt, it leaves a little ash containing a very
small portion of iron. The liquor in which the co-

The petìfect àehronìatic transparence of the lens,
notwithstànding ita similarity in chemical pn^er-

worthy of noticé. The black pigment of the cho-

slightly soluble in alkalies. When dried and ignited,
it bums as eàsily às a vegetable substance, and the
ash contains much iron. From these observations
it may well be suppòsed that the circulating blood
is decomposéd on the interior surfiice of the choroi-
dea, leaving there its colouring matter, which is re*
quired fòr the pùrposes of vision, and conveying
the i^étóainder tó the ihner part of the eye perfectly

ceiVed opinion of the presence of gelatine and al-
bumen in the lens is erroneous ? The existence of
free kctic acid in the humors of the lens proves
nothing witìi regard to its suppòsed muscUlàr struc-

256 CHEMICAL PROPERTIES
Of the Fluids that compose the ExcreUons*
I must refer the reader to what I bave already
observed generally oii this subject, and shall prò-
ceed to the individuai species.
- 1. The Fluid of Perspiration.
I bave not been able to make my experìments on
this fluid in any large quantity, the organ that se-
cretes it being extended over so large a surface and
seldom affording much at a time. As to what col-
lects in under-waistcoats after some days wearing,
it must always be more or less altered by spmitane-.
ous decomposition.
I collected on a watch glass a few drops of sweat
as they fell from my &ce, and evaporated them
careftdly. The yellowish residue had ali the ap-
pearance under the microscope of the usuai mixture
of the muriates of potass and soda with lactic acid,
lactate of soda» and its accompanying animai mat^
ter. It reddened litmus, and dissolved in alcohol,
and was without doubt of the same nature as the
analogous matter found in the other fluids. The
alcohol left untouched a small trace of an animai
matter which blackened in the Are, but was in too
small quantity to admit of fiirther examination.
Mr. Thenard dìscovers acetous acid in perspira-
tion, but this acetous acid is produced bere, as in
bis other experiments» from the lactic, by bis mode
OF ANIMAL PLUIDS* 257
of opèratìng. It is well known that litmus paper
reddens instantly when put in contact with the skin
of the living body ; which 3hews that the acid that
produces this eflfect Ì9 not volatile, otherwise it
would be evaporated hy the dry ^urface of the body
which has always a temperature of 86° to 9(f Fahr.
2. Urine.
We possess many analyses of urine, botli in a
healthy and diis^ased state, but none of them gives
^ very extended view of the subject; and it is cl^ar
that the ai^dysis of morbid urine acquires its chief
interest from being able to compare it with that pf
bealtbf
A. The acids of the Urine.— Tì^ìq acidity pf
Jiealthy urine has generally been attributed to the
phosphoric acid. By the chemical change which
the blood undergoes in the kidneys, a large portìLon
of its consti tuent parts are acidifi^d; SQ that the
blood which enters alkaline iijto the renai arteries^
retums from tìie renai vess^ls Ipaded with many
^cids, som? pf which did not at ali exist in the
blood at itsentrance, and others were present in yery
minute quantityonly. The acids of the urine which do
not atall exist inthebloodarethesulphuric, urie, and
spmetimes the benzoic ; the others are the phospho-»
rio and l^ctic. The muriatie and fluoric acids ap-
pear to pass from the blood to the urine without in*
crease in their proportional quantity. As by the
}j^ws of chemical afSnity these acids will unit^ with
yoj.. m, ^
258 CHEMICAL PROPERTIES
any alkali that may be present, and saturate them*
selves with it in the order of the force of their
respective affinities, it must follow that where the
quantity of alkali is insufficient to saturate ali the
acids present, the weakest acids must be those that
will remain uncombined and will give the urine its
acid properties. These therefore must be the lac-
lic and the urie.
It is so generally known and so fuDy proved that
the urine contàÌTìs the phosphoricj muriatica aìià urie
acids, that it is usel^ss to add any thitig furtlier on
this subject.
Urine contains the Jlz^pric acid. In my analysis
of bones I bave found that human and ox bone
contain as much as two per cent, of fluate of lime.
It is therefore naturai to suppose that the earthy
phosphates dissolved in urine, which are chiefly de-
rived from the decomposition and absorption óf
bone, should also retain the same proportioh of flu-
ate of lime. To prove it, I precipitated a largo
quantity of urine with caustic ammonia, collected
and calcined the precipitate, ìiiixed an ounce of
it with as much si4phurìc acid, and then heatèd the
mixture modefately in a platina crucìble covered
witii a glass piate prepared for etching. After some
hours I removed tlie glass, took off the graver*s
wax, and found the lines corroded by the fluorìc
acid vapour.
OP ANIMAL FLUIDS. 259
Urine saturated by ammonìa, fitered, and mixed
with muriate of lime gives also a good deal of phos-
phate of lime, containing no fluoric acid. The
urine therefore contains no other fluate than that
of lime.
The sulphtiric acid is also foùnd in urine. The
alkaline fluids merely neutralized by acetic or mu-
riatìc acid, and then mixed with muriate of barytes,
give no indication of sulphuric acid. But if the
residue left after the evaporp^tion of these fluids, bè
first calcined, and the saline part then extracted by
lixiviating the ash, and tréated with muriatic acid
and muriate of barytes, a notable quantity of sul-
phuric acid is found^ produced from the sulphur
contained in animai matter. But with urine the
appearances are very different. Muriate of barytes
added to it forms immediately a (^opious precipitate
of sulphate of barytes; and I bave constantly found
that the quantity of sulphuric acid in urine exceeds
that of the phosphoric acid. Rouelle the elder long
ago detected sulphuric acid in urine, but this was
considered as an accidental circumstance: I bave
however very goo4 reason.for supposing this acid to
be a most essential constituent part of urine. The
production of this acid takes place in the kìdrieys,
and the action of these organs resembles combustion
in this respect, that part of the constituent elements
' of the urine, such as the sylphur, phosphorus, the
radicals of the alkalies and earths, &c. become ox-
idated to their mcmmum : and bere also the kid-
s2
260 CHEMICAL FROPERTIES
neys generate some acids with compound bases.
The remainder of the blood gives rise to the urea,
which being formed from the materials of the blood,
ought to contain more azote in proportion asa great-
er number of the other eleraents of these materials
has been acidified. It would however be incorrect
to consider the production of urine as an excretion
of the azote Which is in excess in the animai econo-
my, because it appears thattheamount of itsquantity
in the constituents of urine is not greater than in
the constituents of blood. We might with as much
reason consider the kidney as an organ for oxida-
tion ; but it is certainly an error to believe that any
organ except the lungs has the office of removing
one particular element in a greater proportion than
the rest.
I at first conceived that the whole of the sulphur
contained in the blood was acidified in the kidnèys,
and consequently imagined that the same change
might be induced on a part of the azote, the carbon
and the hydrogen. Proust asserts that the urine
contains carbonio acid ; but it isvery difficidt to esta-
blish the certainty of this fact, because the urea is
decomposed by a beat even inferior to that of boil-
ing water, and produces carbonate of ammonia,
which is decomposed by the free acid of the urine,
and carbonio acid is disengaged. I am rather dis-
posed to believe that urine does not contain car-
bonic acid, because no bubbles of air are ever seen
lo form on the sides of the containing vessels ; and
OF ANIMAL FLUIDS. 261
if urine stili warm be thrown on any substance
"whatever reduced to powder, such as powdered su-
gar, no eifervescence ensues. Urine is found to
contain no nitric acid. If the residuura from eva-
poration be treated With alcohol, and the undissolv-
ed portion, (which must contain ali the nitrates of
the urine) be exposed to fire, it will exhibit no sign
of detonation : although this phenomenon is very
perceptible whenever a very small quantity of m-
trate of potass or even of nitric acid bas been add-
ed to the urine. Lastly, I found accidentally that
the whole of the sulphur contained in urine is not
acidiiied. I had made use of nitrate of barytes to
precipitate the sulphuric acid in urine, and had pre-
viously added to the latter some nitric acid in order
that the phosphate óf barytes might be retained in
solution. Aft^ having separated the sulphate of
barytes, I precipitated the phosphate by ammonia,
and after having filtered the ammoniacal liquor, I
evaporated it. During its evaporation it deposited
small white shining crystals; exceedingly hard, in-
soluble in water, in acids, or in caustic potass.
After subjecting them to many experiments, I at
length found them to be sulphate of barytes. In
repeating the experiment with miniate of barytes
and muriatic acid, in order to preventthe precipi-
tation of the phosphate of barytes, no sulphate of
barytes was formed. The production of this salt
is the more singular because the nitric acid pre-
sent was even supersaturated with anunonia. Instruct-t
\
262 CHEMICAL PROPERf IE5
ed by this experimènt, I precipitateci another por-
tion of urine with nitrate of barytes, and after fil-
tering evaporated it to dryness, and burned the re-
siduum with a fresh quantity of nitrate of barytes.
The ashes treated with ttiuriatic acid left a consi-
derable quantity of undissolved sulphate of barytes.
4. The benzoic acid is found, according to
Schede^ in the urine of in&uts. I bave noi
bèén able, in my experiments, to discover the least
trace of it^ and I much doubt whether it be contain-
ed in acidulous urine.
5. Lactic acid. It is principally to this acid that
urine owesits acid propertìes: and ìf I may be
allowed to speculate on final causes, I should say
that it is destined to hold the earthy phosphates in
solution, and obviate the dire effects of their deposi-
tion in a solid mass. In order to ascertain the pre-
sence of this acid, the urine must be evaporated
to the consistence of syrup, and treated with al-
cohol. The substance which remains undissolved
is acid, and bythe addition of ammonia is decom-
posed; andthe lactic acid combined with the am-
monia becomes soluble in alcohol. From its solu-
tion in alcohol the ammonia is disengaged by quick-
Ume, and from the new salt thus formed the lime
may be separated by oxalic acid, which leaves the
lactic acid dissolved in water. By this process a
small part only of the lactic acid contained in tbe
OF ANIMAL FLUroS. 263
urine is obtained» the greater part, together with
the lactate of ammoma> being carried off by the
alcohol.
B. The deposit from urtile.
Urine, by cooKng, affords a deposit which varies
considerably in different circumstances, not only
in quantity, but also in extemal characters. When
it is abundant the urine becomes turbid throughout»
a grey powder is precipitated, and after continuing
£ov some tim^ at rest, the precipitate is found at th^
bottom covered with a mucous stratum. The de-
posit gradually acquires a red tinge, and after some
time is found perfectly crystalUzed» When the
urine does not become turbid, there only appeara a
tbin cloud scarcely discernible^ which by rest sinks
to the bottom or collects in light transparent floct
culi, in which there are sometimes formedjt after 24^
hours, red crystals^
AH urine, when newly evacuated, contains a mat»
ter suspended in it, which in some degree affects
ìts perfect transparency. This matter is the mucus
of the inner coat of the bladder. If the urine^
while yet warm, be poured on a filter, it will pass
per&ctly clear, and the mucus will remain on the
filter in the fbrm of transparent and colourless
flocculi. The deposit which afterwards takes place
in filtered urine is pulverulent, andnowìse mucous r
which proves that it is from admixture with the mu-
cus of the bladder, that the flocculent appearance».

266 CHEMICAL PROPERTISS
In catarrhus vesicas the urine is loaded wìth an
enormous quantity of a mucous matter whìch is
suspended in it. This matter is a true mucus,
although, in consequence of the morbid affectioii
of the orgam which produces it, its characters are
different from those of healthy mucus. If it be col-
lected on the filter, in proportion as the water is
absorbed, it becomes more and more mucous and
vìscous ; and, during the desiccation, it becomes
transparent and gree^sh. fiy maceration in water
it recovers its mucous character, undergoes after
some time an acid fermentation, and acquires a
purulent appearance. In a word, the mucus of
the bladder, when diseased, approaches more nearly
to that of the uose, and differs much in its proper.
tìes fÌTom the secretion in its naturai state.
There is stili ano^er morbid condition of the
urìnary passages, in which the urine carrìes along
a matter mechanically suspended in it, and which
has so dose a resemblance to that produced by ca-
tarrh, that inattenti ve practitioners easily confound
the one with the other. The urine when filtered
leaves a mucous matter pn the filter, which however
does not become transparent by desiccation, but
gives, on the contrary, a white powder appearing
only to the touch. This powder consists of phos-
phate of lime, and the ammoniaco-magnesian phos-»
phate, mixed with the mucus of the bladder. The
urine in this disease has lo$t ali its free acid, it does
not affect the colour of litmus paper, and I hav«
OF ANIMAL FLUID8. 267
scHfnetimes even seen it restore the blue colour of
litmus when it had been reddened by vinegar. In
obsérving this reaction, the paper should be inspect-
ed immediately; if itbe allowed to dry, it reddens
firom the decomposition of the ammoniaca! salts,
and this happens even when the paper is immersed
in a solution of neutral muriate of ammonia, or
even when the ammonia is in excess. The urine
in this disease has also the property of yielding a
precipitate by common muriate of mercury, in
the same way as during a paroxysm of fever : a cir-
cumstance which is owlng to the absence of the
free acid*.
«
The secondary precipitate which is formpd in
urine, which has been filtered while stili warm, is
pulverulent, and contains, as is already known, the
urie acid in abundance. In the first moments after
it3 formation it is of a greyish white, but it gra-
dually acquires a réddish hue, and the pulverulent
"^I once had occasion to treat a man attacked M^ith this disease.
I endeavoured by large doses of phosphoric acid to supply the de-
ficient acid in the urine, but without being ablc to effect any alter-
ation whalever. The dose was ai length increased till it purged the
patient, when the urine suddenly resumed its naturai characters,
and became acid^ transparent^ and deposited urie acid. But these
salutary eflfects disappeared with the purgative one, and they could
not be again reproduced. After the phosphoric acid had been em-
ployed in vain, the acetic and sulphuric acids were given, but
without success. AlkaUne remedies had no efiect either benefìcìal
or in^urious» and the disease stili continues, having produced ast
great degree of debility in the inferior extremities.
26Ì CHEMICAL I>R0PERT1È$
tnatter assumes at the same time a crystalline fbrm*
Tlie change is efFected stili more quickly when ex-
posed to the immediate contact of air, than when
the deposdt is covered with urine. The greyish pre-
cipitate which is first formed is soluble in caustic
alkali, without the evòlution of ammonia ; but in
proportion as it becomes red and crystallized, pot-
ass disengages from it ammonia in abundance. It
isevident, therefore, that the crystallization of the
precipitate depends on tÈie formation of urate of
ammonia with excess of acid, which appears to con-
stitute the red crystals which fprm in urine by cool-
ing. I think I bave observed that the mucus is in
a great measure concerned in this change in the pre-
cipitate, since it takes place more slowly, and in a
less degree, in urine which has been filtered. That
species of urine which on cooling becomes milky
and appears like a mixture of day and water, yields
about one thousandth of ìts weight of precipitate.
The deposit, treated with acetic acid, is partly
dissolved and gives a yellowish solution, from which
a precipitate is thrown down by carbonate or prus**
siate of potass, as well as by ìnfUsion of galls, but
net by the caustic alkalies. The quantity dissolv-
ed is greater, and the yellow colour more intense
when the urine has not been filtered before cooling j
which appears to prove that the substance dissolved
by the acetic acid is in both cases mucusj of which
a part has been dissolved in the urine, and since

the urie acid. It is t^is compound which is gradually
decomposed, and gìves rìse to the crystallized su-
perurate of ammonia* The deposìt contains none
of the earthy phosphates. The muriatic acid di-
gested with the deposit, and then saltirated with
ammonia, precipitates nothing. Subjected tp fire,
the deposi t burns, and leaves at length, and with
some difficulty, a very small quantìty of a fused
ash, which consists of carbonate of soda, proving
that the deposit oflen contains a small quantity of
superurate of soda, that insoluble salt which, ac-
cording to the experiments of Dr. WoUaston, pro-
duces the gouty concretions of the joints.
The secondary deposit of healthy urine, there-
fore, is not urie acid, but a combination of this
acid with an animai matter, which appears to he a
portion of the mucus of the bladder dissolved by
the warm urine. The deposit contains stili a trace
of superurate of soda, and by spontaneous decom-
position there is formed superurate of ammonia
which renders it crystalHne.
Itis to be presumed that urie acid, which is de-
positedinthe bladder and forms calculi, contains
this same animai matter, which ought accordingly
to be an essential constituent of ali calculi formed
in the bladder. I bave thus found it in two differ-
cut calculi which I examined with this view. The
fdlowing is the mode of separating the urie acid
from the animai matter. The calculus is dissolved
270 CHEMICAL PROPERTIES
in caustic alkali, and a precipitate obtainedljy add-
ing to the solution muriatìc acid in excess« The
precipitate consists of urie acid; and a combinatìonof
the animai matter with muriatìc acid, which may be
carrìed ofF by washing the precipitate freely on the
iilter. The muriatìc compound is soluble in pure
water, and is again precipitated by the additìon of
muriatìc acid, or by allowing it to drop into the
acid liquor which has passed tìirough the filter.
The urie acid remaining on the filter is in a state of
purity greater than any that has been hitherto the
^ubject of examinatìon.
C, Anàlysis of Urine.
I bave béen at much pains to arrive at as accu-
rate a knowledge as possible of the precise compo-
sitìon of urine, both as to the quantìty and condi-
tìon of its constìtuents. The task has been labori-
ous, difficult, and often extremely complicated.
It would be trespassing on the patience of the So-
ciety, were I to attempt at present to give an ac-
count of ali the details, and such is the nature of
an exact analytical investìgatìon that it admits not
of a brief recital. I shall therefore content my-
«elf with communicatìng the general result which
h as foUows :

With regard to the relative proportions of these
ingredients, it is very probable they may vary inde-
pendently of disease. I believe, howeyer^ that in
urine they are never very differente unless from
pathological causes which mat$rìàlly affect the
faealth. /
I should also observe thaf in the 17.14 paxts of
lactic acid, lactate of ammonia, &c. thejre exists a
^uautity of water which it ìs nòt possible to ab-
272 CHEMICAL PROPEIITIES
jstract without the rìsk of decomposing these sub*
stances. The quantity of urie acid always varies
according to the individuai, and also in the same in*
dividual from different circumstances which bave
little influence on health. In the above analysis it
was determined from urine which became turbid
throughout during its cooling, and which during
its deposition resembled water mixed with day.
The earthy phosphates contain rauch more mag^
nesia (as mach as 1 1 per cent) than in the bones
or the ashes of blood. Of the cause of this I am
ìgnorant ; but I bave likewise found much more
potass in urine and in milk than in the blooO.
The silex was not detected by the combustion of
drìed urine : fbr in this way it might bave been
considered as a constituent of some animai matter
dissolved in the urine, I discovered it by treating
evaporated urine with alcohol, then with water, and
afterwards with muriatic acid, which left the un-
dissolved silex in the form of a grey powder, which
fused with soda produced a transparent glass, and
which by the decomposition of the glass was con-
verted into the gelatinpus state. The water we
drink, and which supplies the continuai waste of
that element by perspiration and by urine, always
contains silex, which appears not to separate from
it in the body, and which tfaus makes its exit in
the same state in which it eatered. It is evideiit
that this earth should be found dissolved in the

Butter 4.5
Chee.se 3.5
Whey 92.0
As 92 parts whey contain 4.4 sugar of milk and
salts, it foUows that cream contains about 12*5 per
cent, of solid matter.
It is very remarkable that scarcely any other al*
kali than potash is found in milk. I bave bumt a
quantity of dried milk, and bave dissolved tìie mu-
riate of the ashes in spirit of wine, and the alkali
left undissolved by the alcohol, neutralized by the
sulphuric acid, produced only sulphate of potash. I
know not how far this observation is applicable to
other kinds of milk, or to milk taken from other in-
dividuals.
Cheese, which is destined to be part of the nou-
rishment of the young animai, has, very pecidiar
characters, which, as it would seem, fit it for this
office. It admits easily of incineration, affording
a white ash which contains no alkali, and which
forms as much as 6.5 per cent, of the weight of the
cheese. This ash contains principally earthy phos-
phates with a little pure lime : but it contains nei-
I
i
*«<
ÙxéT alkali nor oxide of iron. % Cheese digested with
concentrsted muriatic acid yìelds the gn^ater part
of its phosphates to the acid, and it afterwards burns
mthout leaving any ash» But the cheese may be
precipitated from the milk by an acid vnithout losing
its phcMsphates. It appears then, that the latter
arenot yetformed» but that a slight affinityonly
is requisite to their production. We may con-
clude that nature has thus sought to assist the di-
gestive powers of the young during a period of
their lives, in which there exists in the ceconomy
the greatest demand for earthy phosphates for the
purposes of ossification, which is at that time ad-
vancing so rapidly.
Cheese is generally considered as a substance in-
soluble in water, and yet a great part of it is in act-
ual solution in milk. A solution of it in water may
be obtained, if cheese precipitated by an acid and
well expressed, be digested with carbonate of bary-
tes or carbonate of lime. The carbonate is de-
composedwith effervescence, andthe cheese quitting
the acid is dissolved. The solution is yellowisl^
and resembles a solution of gum. Evaporated to
dryness it leaves a yellow mass which easily r^dis-
solves iii water. The solution boiled in an open
vessai, becomes covered with a white pellicle, pre-
cisely as milk does, and acquires the smeli of boiled
milk* The membrane is almost insoluble in water,
and appears to be a produci by the action pf air on
the dissolved cheese.

276 CHEMICAL PROPERTIES OF ANIMAL FLUIDS.
With the minerai acids cheese produces the same
combinations as albumen and fibrina although the
neutral combinations are less soluble thàii those of
fibrin. A great excess of acetic acid is required in
order to diiSsolve the cheese, and the neutral com-
bination with this acid appears to be insoluble.
Cheese is easily dissolved in alkahes.» Its solution
in acetic acid as well as in ammonia, becomes co-
vered with a small quantity of cream every time
that the cheese has not beent well separated fi:om
the butter. Alcohol converts cheese into an adi-
pocirous and foetid substance^

tend outwards, between those muscles, so as not
to press on the axillary nerves and vessels. Its cìn
cumference and base were as hard as a cancerous
breast: the body of the tumòr was elastic, and
seemed divided into sacculi containing fluid: the
sur&ce was irregular, and the prominences gave a
feeling as of fluid contained in cysts. The.skin was
much stretched and discoloured : it had a purpleish
bue, not unUke that of erysipelas ; but its tempera^
ture was naturai. There was no pain until the end
of November, whea a violent attack took place»
with considerable fevei: theso subsided, leaving
the patient occasicoially sulgect to darting pain in
the swelling.

greatly debilitating the patient^ .
The tumor increased but little after this periodji
nor was pain complained of till the 1 2th of January ,
when excruciating and darting sensations were felt
in the swelling, on the side of the neck, and along
the under part of the arni. These were sometimes
SQ severe, that the patient supposed he should net
survlve them. The circumference of the tumòr
pow beqame considerably enlarged, the prominent
parts continued elastic, and the integuments were
pf a deep purpleish red colour. The continued
pain and constitutional derangement, accompanied
with difficulty of breathing, confined him to bed
from the 19th of January, and were not alleviated
by any locai or general treatment.
On the 8th of February, the tumor measured six
inches and a half in the long axis, and six in the
short; the centrai point began to project intp a
nippleJike eriiinence, whicji was apparently only
coverà with cuticle. It was surroiinded by a beauti*
fui deep red and purple coloured disk, the diame*
ter of which was two inches and a half; the skin

gradually shaded with purple and red streaks. It

already described, darting sensations were added,

the kteral ìncrease of the swellìng had been as-
tonishìng, as its transverse measurement was now
fburteen inches. The skin, about two inches above
the part which burst and afterwards cìcatrìzed (ex-
cept the small aperture through which the fluid had
oozed more than a fortnight,) was extremely thin,
prominente and likely soon to give way.
llie circle, where the integuments first ulcer-
atéd, was considerably enlarged, owìng to its dis^
tension by fluid, the aperture having been for some
days closed ; the new formed skin was changed
into a whìte and fibrous substance, which adhered
with great flrmness. The pain in the tumor wi^s ^t
this time so particularly violenta from the integu-
ments being so much distended, that I felt inclined
to make a small puncture ^o afibrd him temporary
relief ; but on the evening of this day, the integu-
ments gave way, and a considerahle quantity of
bloody serum was discharged, which occasioned
immediate ease ; but fluid stili seemed coiitained
in several parts of the tumor.
March 10. — Thedifficulty of breathingincreased,
and he had coughed up blood. The integuments
at th€i most convex part of the tumor were begin-.
ning to ulcerate, and there were several apertures,
through which a probe might be passed into it.
The discharge was stili considerahle, though it did
pot tend to the diminutioQ of the» swelling.
Q&4t FUNGUS H^MATODES,
The pain, difficulty of breathing, an<ì other symp*
toms grew more and more distressing, and diarrhoea
carne on, with excruciating pain in the bow^s.
The tumor assumed an appearance òf sphaceW
tìon at one part, and the discharge became very
ofFeosive,
Although the powers of the constitution were
reduced to the lowest ebb, a disposition to form
these tumors stili remained, as one made its ap-r
pearance on the rìght side of the neck, s^nd ano*
ther on the bs^ck, and the former became consider-
ably enlarged, Violent sickness accompanied with
tormina and tenesmus, and other dysenteric symp*
toms continued till the 16th of M^irch, when
death took place,
After insulating the integuments from the base
of the tumor, and dissecting back those covering
the chest and posterior part of the arm, the sui^
perficies of the di^eased piass was found tq be form*
ed of a congeries of yaripus-sized dark purpl^co»
loured tumors, 'wbich had extend^d bet^een the

as to impede their fiinctions^ or produce any mor-'

The morbid growth weighed four poutids aver-
dupois weight, and when the integuments and
cellular substance^ covering the various-sized tu-»
mors which formed thè whole, were removed^ and
the axiliary nerves and blood vessels cleaned, it
bore much resemblance to an enormous bunch of
black Muscadine grapes*

Ali the tumórs situated on the external part of
the large one, had that spongy elastic feel peculiar
to it, which so singularly characterizes this horrid
diseasé, and which h^s been described by those
who bave written on fungus haematodes, but par-
ticularly by Mr< Burns^ Mr. Hey, and Mr. Ward-
fop.
Several of the tumors were cut through, to ex-
amine their internai structure and contents ; some
were found to be composed of a soft medullary
substance j like braiii mixed with coagulatéd blood \
others wìth a dark grey-coloured substance in con*
astence similar to the former ; a few were of a
blackìsh colour, but had the same arrangement of
structure as the former, and the fluid expressed
firom them was exactly like the pigmentum nìgrum
<m the choroid membrane of the eye, or die inky
fluid in the bronchial glands, and when their con*
tents w^e pressed out, the condensed cellular
cysts only lemained, with a loose iìbrous retiou-
lated arrangement of their internai parts, with the
ramifications of several minute blood vessels.
The main bulk of the disease was next divided j
it presented an irrcgular union or blended ap-
pearance, similar to what composed the other tu-
mors, and the contenta were confined by strata of
apparently fibrous reticulated condensed cellular
substance; but there.were three cavities, each of
which contained about an ounce of loose coagu-
lated blood.
The sloughing- process on the anterior part of
the tumor had not penetrated beyond the integu-
ments, but had changed that part of it beneath
them into a white sloughy looking substance.
The blood vessels were numerous, but very
smsdl.

consistence, but of a cinerìtious colour, and in-
jtersected with cellular septa.
There was a small tumor similar to those in the
liver, between the layers of perìtoneum which form
the ligamentum suspensorium hepatis; and two
on the front of the pancreas, one about the mag-
Hitude of a pìgeon's egg, the other the size of a

XHE subject of the following detaìl was a gentle»
man residing about ten miles from Worcester, sixty-
three years of age. In the early part of his life>
he had served in the American war, in which, he-
fbre he was thirty, he lost his right leg. He was
of a fair and florid countenance; about five feet
ten inches high, and of a strong and manly figure,
his chest being particularly capacious and well
formed. He was a man of qvick feelings, but of

grett resolution and bene\folence. His habits were
temperate. The loss of his limb prevented hi*
walking much, but he generaljy spent many bQ^^ir*
in tibe day on horseback»
For ^xteen or eighteen years, he had occasion-
ally hawked up a little mucus, tinged with dark cof
loured blood^ without cough, to which he had ne^-
ver been subject. He had had several attacks of
rheumatic fever; and wa$ so much troubled with
indige$tion, that for some years he had been obliged
to regniate his diet with great care. He had also
been several times affiscted with a peculiar kind of
dyspncea, which I shall presently bave occasion tp
describe, and which was most violent after his first
attack of acute rheumatism^ The dyspnoea was
never attended with congh, but always with morii
or less expectoraùon of mucus tinged with dark co»*
loured blood.
In th^e early part of last wìnter, he was vùmcìk
troubled with rheumatic pains, which prevented
hi» ufiual exercise oh h<Mrseback ; and at the $am^
time the symptoms of imligestion increased, and
the dyspncea returned, which last Uniformly carne
on early in the morning, and obliged him to sit up
in bed. These symptoms sooii yielded to the use
of rust of iron, extract of gentian, and infiision of
bark, with gentle aperients, chieily magnesia; and
fbraweek or ten^iays seemedwholly tofaave left him»

They again returhed however, notwithstànding
the continued use of the medicines^ and the dys-
pnoea began to be more troublesome, and to harass
him during the day. It was now attended with
some frequency of pulse, but without any other
symptom of fé ver. He said the dyspnoea was al-
ways least after dinner, and seemed relieved by eat-
ing animai food and drinking a few glasses óf wine*
He complained much of a sense of sinking and de-
bility at the stomach, and stated that he could re*
Jieve the dyspnoea by pressing hard on the epigas-
trio region, or by a fuUer inspiration than usuai.
The pulse was never either intermitting or irregi^lar
at any period of the disease*.
The character of the dyspnoea was very peculiar.
It consisted of about twenty full, deep, and quick
inspirations, succeeded by perfectly iree breathing,
for perhaps a minute, when the paroxysm retumed.
After several such alterations, the dyspnoea, in the
earlier periods of the complaint, often ceased for
many hours. In these intervals, as well as in thè
short intervals between the paroxysms, the patient
could lie in the horizontal position without brìnging
on the dyspnoea, till within a very few weeks of
h:s death.
* Unless it be regarded as an exception to this^ that ìa the lat-
ter part of his illness, it was slower during the paroxysms of dys-
pnoea, than in the intervals between the paroxyHns.
Oa^ANS OF BESFIRATIQ^. 293
Yarious antispasmodic and other medicines were
aow tried without effect«
Having exposed himself to a cold wind on the
22d of last March, (for he stili continued to ride
out occasionally,) he experienced a sudden ìucrease
of the dyspnoea, and the pulse was for the first time
rather hard. Althouglv there was no cough, I ad-
vised the application of leeches, and afterwards of
a blister to the chest, which gave considerable re-
lief. This, however, proyed of short duration, thQ
sense^ of aebility and fits of dyspnoea evidehtly in*
creasing, though unattended with cough or fever,
and the pulse becoming more frequent,
4
On the 30th of March, Dr.^Edw. Johnstone of
Birmingham was requested to see him, with me.
It was agreed that he should take stomachic
draughts with a small quantity of the vitriolated
iron, and occasionally an anodyne draught, with
tincture of opium and camphorated mixture, whichf
be had been using.
Within two days after this, he was attacked in
the night with so alarmipg a traiu of symptoms,
that Mr. Ricketts (the surgeon under whose care
he had been from the comipencement of bis illness)
hardly expected him to survive till mojming. When
I saw him early in the n^orning, I found tji? dys-
piioea extreme^ but sjiU ^ppearìng in paroxysms fi^

àbove described, uhattended with either cough or
fever. The piilse was very feeble but regular, and
appeared to be about 1 60, though it could not be
accurately counted, Laxative medicities ànd the
occasionai repetition of the anodyne were advised.
Next day, (Aprii 3d) the symptomt? havitig by no
nieans abated, Dr, Johnstone was again requested
to meet us,
We now considered the case as bop^less, but <m
account of the great frequency of the pulse, agreed
to make a cautious trial of the ibxgiove, hoping
that it might, by lessening the frequency of the
pulse, produce some xnìtìgation of the symptoms.
This we added to the anodyne draught; and di-
rected two grains of ipecacuanha and four or fìve
òf rhubarb to be given occasionally, fbr the pur-
pose of excitiag the bowels.
1?HiiIe the pulse and breathing continued in the
state bere described, the sense of anxiety was ex-
treme, and the feelings of the patient such, that he
said he would rather die twenty times, than pass
oné such night as the two làst* He was now oc-
casionally affècted whh a degree of delirium. It
is on^ of the peculiarities of this extraordinar}-' case,
that even when the fits of dyspnoea were worsrt, the
patient never had any swelling of the jugular veins,
unusual beating of the carotid or temporàl arteries,
òr other symptoms of impeded return of blood irpiu

^ SQon. after the fir«t dose qf rhubartx and ipec^cu-
>Q^ was giveu bina, he was seized with vovnìtivig
ancj violent str^iming, which, although there was
.but little brought up fiom tha stom^ch, continued
.for a cousld^rable time. I was not displeased at
^tfais eSactp asf I |had been long in vain urging bim
. to take an emetic. Tl^e change of symptoms wbich
^etiisued was very singular* The pulse at once lost
. its great frequency and feebieness, and became a
good steady pul^e of from 96 to 100. Ali appear-
ance of dyspnoea ceased, the patient conceived him-
.96if aloió^t reaiored to bealtn, and said that if he
recovered, the em^c had eaved him.
^ I remained witìi him several hours after this,
during whìch he continued perfectly easy, and tìhe
pulse was strong and good. I left him about six
o'clock in the morning, telling him, that, as he was
so much better, I should not see him again till
next day.
On my return next day, I found that toou after
I was gone, the dyspnoea had recurred with great
viole&ce; but the pube, instead <^ bei^g feeble and
extremely frequenta was now^oply about HO or

blood-lcttìng ón the following moming, to about
the same extent, by which the symptoms were
greatly relieved. The first blood drawn, shewed a
little of the buffy coatj but there was no appear-
ance of it in any of the succeeding blood-lettings.
As mid-day approached, the fits of dyspnoea again
returned, but by no means to the same degree.
They had now, for many days, shewn a periodic
tendency, being evidently worst about one or two
o'clock, both in the day and night*
Wc then gave the patìent a scmple of ipecacu-
anha, whichproduced repeated vomiting with much
straining, and another very complete remission of
the symptoms. Towards midnight, however, the
fits of dyspnoea again returned, stili, as usuai, \vith
perfecUy free breathing between them, and without
cough or fever. The pulse was a little above 100,
• stròng and good, and in some degree hard.
On the 6th of Aprii, I wrote to Dr. Baillie, giv-
ing a full detail of thìs very unaccountable train of
symptoms, stating fhat blood-letting and emetics
were the only means which had latterly afibrded
much relief, àpd that the relief from emetics had
beeh the most complete* I was not then awàre,
• that, although more immediate, it was of shortér
duration Ihau that firom bloodJetting, and that, at
an earlier period, the symptoms had been wholly
removed for a little time by bark, geiì^tian, and nist
of iron. Dr* Baillie advised the repétition of th^
emetic, and the use of such tonic medicjnes as at
th^ ^ame time possessed some antìspasmodic power.
Befbre I received Dr. Baìllie's answer, the patient
refusing to submit to the repetition of the emetic,
we again had had reconrse to blood-letting; and as
Dr. BailHe had noi mentìoned blood-^etting» I
wrote to him on Aprii lOth mentioning what had
happened since my last letter. In his answer, he
observed that the symptoms could neither arise from
inflamtnation nor water. He recommended the re-
petitìon of blood-letting in the more severe, of
emetics in the slighter attacks, and the use of such
tonic medicines as had formerly been found usefiiL
The patient would on no account again submit
to the operation of an emetic, and such symptoms
of debiEty soon began ^ to ^hew themselves, as de-
terred us from a frequent repetition of the blood-
letting. After thjB third blood-letting, (which was
to the extent of about six ounces, and was per-
formed on the moming after the last emetic) the
relief was more permanent than on any former oc-
Casion. Within the succeeding ten days small
quantities of blood were occasionally taken from the
arm. At first the loss of two or three ounces gave
relief; but at length little or no advantage was de-
rived from bleeding to this extent : and as the leg
and stump began'to swell, and symptoms of water
in thè chest appearéd, the patient being now un-
able at any time to lìe in the hprizont^lposition ;

after deatb. On a general view of the abdominal
viscera they appeared healtliy, with the exception
of a greater degree of redness and a more vas*
cular appearance of the small intestine^ tban ìs
usuaL Our time for the inspection of the body
being rather limìted, we proceeded ìmmediately to
the examinatìon of the thoracic viscera, where it
was evident that the immediate cause of the disease
hadexiated.
On opening the thorax, àbout three qttarts of
water were found, chiefly occupying the right side.
The rìght lobe of the lungs appeared diminished
in size ; but, not more than was to be e^ected
irom the quantity of water found in this side of the
thprax. The whole of the lungs appeared of a
darker colour than usual^ the pulmonary yessels
being in a state of great congestion with very dark
coloured blood. Part of the right lobe, for the
space of about an inch and half in diameter, was
converted into a spbstance like liver» and at this
place only, there was ^n adhesion of the pleura^
A iBmall part of the edge of this lobe W9S of a white
ccdour. In ali other respects the lungs were
healthy.
Tlie pericardium was found every where firmly
adbering tp the heart, and the heart itself, especi-
ally on the left side, appeared gf a dark red colour.
There was no other indication of disease in it*
The semilunar ^nd Qther yalves appeared in the
naturai state.
OROAXS O]? RESFIRATION. SOI
Most of these morbid changes were apparenti/
the con^equences^ net the cause, of the disease.
llìat the fluid found in the chest ìs to he regarded
as a consequence of the disease is obvious; for tìie
patient, till mthjn about a month of bis death,
couldy evenin the shortest intervals of the dyspnoea,
lie in the horìzontal position without any inconve-
nience. That the inflammatory afiection of the
heart must be regarded in the same point of view,
appears from a variety of circumstances ; and par-
ticularly from this, that, at an early period, the
syxnptoms were whoUy removed by the use of bark^
iron, and gentian, and the patient aiways found
himself easiest after eating animai food, and drink*
ing wine»
It is almost unnecessary to observe, thiat, had
the dyspnoea arisen from the inflammation of the
lieart obstnicting the passage of the blood through
the lungs, it was impossible that the patient could,
every five minutes, bave had an interval of perfect-
ìy free breathing.
The pericardium every where adhered closely to
the heart, giving reason to suppose that the adhe*
gioii had been of late date*. It may appear at first
view very surprìsing, that inflammation of the heart
dionld bave existed, for however short a time, with-
out foetraying itself by any of its diagnostic symp-
toms« There was no fever, permanent dyspnoea,

or cough*; and the symptomS) which occaèionally
attend ìnflammation of this organ, were also
absent ; viz. irregular pulse, palpitation, and sy»-
cope. In the coUectìons of Bonetus and Morgagni^
the reader will however find cases related, which
prove that there is a chronìc inflammation of the
heart, which, not impeding its functions, may exist
without betra}dng ìtself by any syin{rix>in j and can
only be detected by dissection.
We might at first view be inclined to suppose,
that the héart is subject to this species of inflamma-
tion from its being an organ of very duU feeling
notwithstanding its importance ; (or it has met ^th
severe woundst; worms and other extraneous bo*
dies bave lodged in ittj and abscesses and ulcera-
tions bave formed in it§ , firequently without the pro-
duction of any painfìil sensation, and wbat is sttU
more extraordinary, of any material derangemrat
of its functions* ' But we find the same species o£

htóTe, Sir John Pringle's Account of the diseases of
the array, and in tlie fburth volume of De Haen's
Ratio Medendi. The case before us, may be re-
garded as another ìnstance of the same kiiid ; evi-
dent marks of ìnflammation appéaring on the ìsmall
ìntestines, although the patient liad never com^
plaìned of poin in thern, nor had their functions«
been any fuither deranged, than to require the use
of smail doses of magnesia. The same species o£
ìnflammation has been found in thè stomach itself,
of ali our organs perhaps the most sensìble. D^
Haen, in the work just alluded to, mentions one
case, in whìch the stomach was found inflamed after
death, where there had been no vomiting ; and
anotfier in whìch there had been neither vomiting
nor pain. '
Such cases lead to a curious ìnference, that th«
derangement of fimction in an inflamed part, de»
pends more on the irritation g£ ìts nervesr, than
the dìstension of its vessels : for it appears firom
these cases, that, if the latter exists without occa-
^oning the former, the function of the part is often
little, if at ali, impaired. The nerves appear tp
perfiirm a part in the production of ìnflammation,
Avhi^h is, and probablyever will be, but little under-
ttbod. In extracts from a work by Pedratto, in
the 21 st epistle of Morgagni, and in the Historia
Hepatica of Bianchus, the reader will find cases
and dissectìons related, in which the cause that
produced the ìnflammation, was wholly confined to

one organ, and the ìnlBammation to anothef* Thel
ìnteresting nature of the subject wìll apologìze fer
this digression.
It 13 difiicult to judge of th^ kind and degree of
inflammation by examintng the inflamed part after
death. In the casa before us, the . appearance of
the heart seemed to ali present but myself to indi*
cate a state of active inflammation. To me it ap*
peared too flaccida and of too dark a hue to a£S)rd
this inference ; and its colour seemed to me in a
great d^ee to depend on the same cause» which
gave the dark colour to the lungs, the vessels car-»
rying vety dark coloured blood. It is wcll known
that^ in highly inflamed parts, the blood retains a
very florìd colour long after death*. That inflam*
mation had existed to a considerable degree, there
can be no doubt, ftom the general adhesion of the
perìcardium ; but chronic inflammation of the heart,
as appears f rom the dissections just aUuded to, h
capable of producing even abscess and ulceration.
We cannot conceive that any great degree of
dyspncea could be occasioned by the diseased por*
tion of the lungs, which was coipparatively so
small. Besìdes we may say of this, as of the in-
flammation of the heart, that had the dyspngea
arisen from such a cause, it must bave been .perw*-
nent. We cannot teli whether this changeofstnic-

ture in the luiìgs had exìsted from the commence-
ment of the disease, because it might have existed,
without betraying itself by any sufficiently marked
symptom. But I think we may very positively say,
that it was noi the cause of the disease.
On reviewing ali that has been detailed concem-
ing this extraordinary case, the follawing observa-
tions naturally arise. The explanation which they
alFord must be admitted to be in several respects
conjectural; but I know of no other which can at
ali account, either for the symptoms, or the effect
of the means employed.
It appears, frora the whole course of the symp-
toms, that no permanent course of obstruction to
the circulation through the heart or lungs existed;
And, ih the dii^section, no such cause could be
found : for, that the inflammatìon of the heart only
supervened in the ktter stage of the disease, and
that, when it did supervene, (as in the cases men-
tioned by Bonetus and Morgagni) it occasioned no
obstruction to the circulation, as I have already had
occasibn to observé, are proved by the history o£
the disease. It follows then, that, without organic
derangement, spasm, or any other cause capable of
obstructing for the space of a minute the circula-
tion through the heart and lungs, (for the fits of
dyspnoea never iasted so long as a minute) some
cause existed capable of occasioning such fits ; and
consequently of impeding the oxygenation, or, we

x>ught rather to say, from the late veiy accurate
experiments of Mr. Ellis*, the decarbonìsation of
the blood in the lungs ; and that such a cause did
exist to a greater or less extent, from . the com-
mencement of the disease, appears from the blood
hawked up having always beeri of a dark colour.
This state of the lungs being admitted, does it not
afford a ready explanation of the peculiarìties of
the foregoing ca^e ? We know from direct experì-
ment, that the left side of the heart cannot be ex-
cited by venous blood. This does not seem sur-
prìsing, as arterìous blood is its naturai stimulus*
And may we not safely infer, that the smaller rami'*
fications of the pulmonary artery, and the trunk,
as well as ali the ramifìcations of the pulmonary
vein, which, in the naturai state, carry only arte-
rìous blood, are also insensible to the stimulus of
venous blood, which is the naturai stimulus of the
right side of the heart, and of the trunk and larger
branches of the pulmonary artery. As soon, therfe-
fore, as the decarbonisation of the blood began to
be impaired, the action of the former set of ves-
sels would be impaired in the same proportion.
Would not the consequence of this te, that these
vessels would require a greater degree than usuai of
tliie stimulus of distpnsion to excite them to carry

Blood4etting would necessarily relieve, by less-
ening the quantity of blood thrown into the debi*
lita!ed vessels. The effects of the bloodJetting
would prove more permànent, because they would
continue till the increasing quantity of blood, or
increasing debility of the vessels, again called for
a dimination of the blood. The good effects of
the emetic would be more transitory, but more im-
mediately felt, because, by it, the distended ves-
sels would be immediately enabled to contract ; but,

the same, they would in a short time àgain be op-
pressed. Now ali this was exactly what we re-
peatedly witnessed. The circumstance of the pa-
tient obtaining immediate ease, in slight paroxysms,
by a very foli inspiration, seems to indicate, that
nothing was wanting for the free circulationthrough
;he lungs, but a more perfect decarbonisation of
:he blood.
It may also be seen, why there was no ìmpedi-
ment to the return of blood from the head. For
as the right side of the heart and larger pulmonarj
arteries possessed their naturai stimulus, it is evi-
dent, that, long before congestion could take
place in them, from the cause I bave mentioned,
death would ensue.
It may also be observed, that the deficient decar-
bonisation of the blood could never, in this way,
go so far, as greatly to affect the \vhole mass of the
blood. In the case of a blue boy it does so; because
there, arterious blood is, to the last, supplied to the
left side of the heart and pulmonary system, although
this may be in too small quantity. But bere, the
defèct is first felt in these organs, and consequently
cannot go to any great length without destroyiug
their action.
If these observ^tions be just, tlie foregoing case
aifords an instance of a diseased state of the lungs,
which, 9S far as I know, has not been noticed by
ORGANS OF RESPIRATIOK. S09
writers. And indeed the symptoms were such as
it seems difficult to suppose could bave arìsen from
any of the common causes of pulmonary disease.
It is not unlikely that this dìseased state of thè
lungs, whatever it was, had given rise to the change
of structure observed in one part of them, and
which, could the functions of life have gone on,
\wuld probably have spread to the rest.

CHRONIC RHEUMATISM,

COMMUNICATED
By ALEXANDER MARCET, M.D. F. RrS.
ONJi or THE FHYSICIANS TO GUY's HOSPITAU
Read Nov. 24, 1813.
I H AVE frequenti jhad the opportunity of observ«
ing, for the last six or seven years, that the pro-
fuse and unavailing sweats which often spontane*
ously take place in the early stages of rheumatism^
and exhaust the strength of patients without allevi-
ating their sufferings, are almost in every instance
checked, and the pains proportionally relieved, by
the use of antimonial medicines. Several distinct
instances of this kind were recorded some years ago
at Guy's Hospital in our clinical diarìes, and the
explanation which I ventured to ofier of this para*
doxical result, was, that the profuse flow of moist-
ture from the pores, is not, in ìtself, the circum*

stanca which dìminishes pain in rheumatic afFec-
tìons ; but that the relief is produced by a certain
conditìon of the sur&ce, or peculiar action of the
cutaneous vessels, which, though generally pro-
ductive of moisture, is not necessarily connected
with profuse perspiration^ It is this peculiar ac-
tion which antimoniais are so apt to promote ; and
there is no diflSculty in conceiving, how the violent
and colliquative paroxysms of sweating which oc-
cur in rheumatism, gradually yìeljd to this gentle
and uniform operation*.
The following interesting case, which I think in
eveiy respect worthy of being communicated to the
Society, appears to me to contain ingenious and
instructive hints on the treatment of rheums^sm,
and on various physiological points, and to throw
some light upon the preceding observàtions. It
was drawn up by the patient himselft, a gentleman,
who, although not belonging to the medicai profes-
sion, is so well known in the philosophical and li*
terary world, that bis name, had I been at liberty
to giva it at fuU length, would bave added great
weigbt to the opinions and statements which hi»
paper contains.
* It is probable also that the ìnvarìable tendency of aittimonials
to determine gently to the intestines, may eontribute to this bene-
ficiai eftect. Opium alone, often checks the most distressing
tymptoms, but its mode of operation is altogether diiièrent

sia A NEW MODE OF TREATMENT
**About eighteen years ago," says Mr. C. " Ifc-
ceived a sprain on horseback which occasioned very
violent pain in myloins,and stili more in the left hip,
thigh, and leg, foUowing the course of the sciatic
nerve, and spreading itself over the sole of the left
foot. I was then on the continent at Bruxelles;
and after severe blistering and other remedies, not
finding myself better , I was ordered to try the mud
baths and douches of St. Amand. Having used them
six weeks to no efFect, I proceeded to Paris. I
tried various methods of cure under the most emi-
nent surgeons there, as warm and cold bathing,
vapor, air conducted through a heated pipe direct-
ly to the part affected, warm and strengthening plas-
ters, fumigations, &c. till at length the celebrated
and unfortunate Monsr. De Seaux proposed the
moxa. This was accordingly applied with more
than common severity, and the suppuration was
maintainedlonger than usuai, butwithout effect. In
this state I was, with many other English, put into
a damp prison, and a violent rheumatic afiection fell
upon the injured parts. I remainedin this situation
fifteen months without a possibility of applying any
remedy. Upon recovering my liberty, an English
phywcian proposed to me a quack medicine, known
in Paris by the name of Goderneau's powders*,

powders chemically. They are a preparation of mcrcury. Each

adding strong testimoni^s in its favour,although the
French physicians reprobated it as unfit for human
creatures. Much more con vincedby the Englishphy-
sician than deterred by the French practitioners, I
began this powder ; 'and, after six doses of it, the
pain diminished, and I was able to walk. Time has
since that helped to wear out th'e complaint, and I
bave occasionally been five or six years witìiout its
is not so wliìte as that of calomel. Examined with a lens, small
globules of metallic niercury are discernible, and also some red-
dish particles which are red precipitate. They are wholly volatile
at a low heat 4ike calomelj but volatilization separates them in a
manner wbich proves tbem not to be homogeneous» for the vìal in
which they are sublimed is roarked with threedistinct zones^ white
xed> and grey. Water does not dissolve any sensible portion of
them. Nitrìc acid dissolves the whole of them, and nitrate of Sil-
ver poured into the solution lets fall a quantity of muriate of Sil-
ver corresponding to about nine grains of calomeU The remain-
ing three seem composed of one and a half metallic mercury, and
one and a half red precipitate. By triturating the above sub-
stanccs in the above quantities^ I produced a compound very like
Goderneau's powders^ but rather mòre unìformln its appearance»
This is a very rude preparation of mercury, and the use of it
sbould noi be encouraged. Its efi^ct is to produce a disagreeable
sensation in the stomachi and aflerwards to increase the appetite.
It also purges, and, as I am told, sometimes produces vomita
ing. ' The French faculty excìaim against it, but this they are
apt ìQ do against every medicine more active than orange-flower
water ; and yet they admit corrosive sublimate. The Chevalier
Goderneau was a inilitary man, and a knight of * St. Louis, but no
chemist; and since the revolution has swept him from off the face
of the earth, the care of preparing the powdcrs hasdevolved upon
bis sister, an old maiden ladyi who from ti me to time swallow#
large doses of them for a sore foot, which has the advantage of
^ways being about to heal.

period I bave tried bathing in warm se?i water, in

which had afTorded me relief in Paris, and in the
Bath waters. I bave also used the dry pump there,
vapc»: baths, and heated air, friction, cupping»

acid, James's powders, guaiacum, nitre, cicuta, hy-

which bore a strong analogy to my o^rti, tbougb
the subject was not a human creature» it ^ggested
lo me an cxperiment which I resolved to trjrimme-
diately. A celebrated race-horse \ belonging to a
Bobleman very well known at Newmarket, had been
ctired of a disorder which ha[d ali the symptoms of
rfierraiatism, by sweating in body clotlies, after
every oUier remedy had failed. I therefore clothed
myself in a sufBcient quantity of flannel, and set
out to walk as far and as fast as I could. With the
iitm^st difficulty I proceeded half a mile ; and the
pain I suffered contributed not a little to the effect

of the exercìse in promoting perspiration. 1 re-
tumed home in a profuse sweat, rubbed myself
dry before a fire, and went to bed. In about an
hour I gqt up, found myself very much fatigued,
but in other respects not worse. Forty-eight hours
after this, I fepeated the same kind of exercise, and
found that I could walk a mile with as much ease,
as I had walked half that distance on the first day.
My general sensations were the same as before;
but, as the fatigue diminìshed, I thought I could
perceive an amendment in my rheumatic pains.
Two days afterwards I took my third walk, proceed-
ing as before, and after it I had a better night, less
interxuptedbypain than anyl had enjoyed for eight-
eèn months. From that moment I looked forward
with confidence to a ciire, and I bave not been dis-
appointedr Every succeeding walk has diminished
my suflFerings, and I may safely say, that after the
sixth, I was as free from pain as I had ever been
in my life. The only remnant I bave left to re-
mind me I was so lately a cripple, is aweakness in the
left leg, particularly about the ankle, together with
now and then a slight sensation of numbness along
the sciatic nerve. These are naturai symptoms,'
considerìng that I had been so long without using
the limb; and there is every reason to suppose they
will yield to time and moderate exercise. I bave
. now walked nine times in this manner for the pur-
pose of sweating, and shall continue to do sa pro-^
bably much longer; for I find it of the greatest use
to my general health to counteract the effects^of
sedentary habits.
àia A NEW MOD£ OB* TREATMENT
" I usuaHy proceed to my sweating walks ia the
following manner. Next to my skin I wear stock-
ings, drawers, and a shirt, ali of fleecy hosiery.
Over these I put one, two or three pair of flannel
drawers, one, two or three flannel waistcoats; and
round ray hips and loins I gird six yards of thìck
flannel, making beside the drawers and waistcoats
eight thicknesses of flannel on the chief seat of
pain, and the origin of the scìatic nerve. Over ali
this I wear warm pantaloons and a great coat. When
I have walked one or two miles, more or less ac-
cording to the heat of the day, I am generally in a
profuse perspiration. I return home, take off my
wet clothes, have a couple of changes of well aired
flannel, and then lie down upon a bed not warmed»
I use no means to excite further perspiration after
the muscular action is over ; but, on the» contrary^
rather incline to check it as speedily as I can, tak-
ing particular care however to avoid catching cold.
*^ I do not perceive that the quantity I perspire,.
has any influence on the efficacy of the remedy. I
imagine that a violent action produced in the gene-
ral system is the chief cause of iis salutary effect.
In coti3equence of this opinion, I cease the exer-
cise the moment that a very increasied action is* well
establi^hed. This is fully produced with tlie shov^^
quantity of clothing in moderately warm weather,
by walking from one to two miles. For patients wfao
ar^ very much disabled, the quantity of dothing

When the excitement is well established, I find my
pulse rìse to between 90 and 100, and it is full and
strong.
^^When I bègati to experience relief from this,
mode of treatment, I was eager to prosecute the
cure, and took my walks every second day. Being
now relieved, I resumé them only every fourth,
6ftìsiy or sì^th day, as most conveniente
** I do not find myself under the necessity of any
particular precaution as to avoiding cold the day I
exereise ; and, in this respeet, sweating by muscu-
Jax iK^tion has an immense advantage over warm
baths» vapour, orheatedair; particularly in a cli-
mate so damp as that of an island situated in the
north seas must be. Physiology will easily point
cut many other advantages in exciting perspiration
by a stifflulus which invigorates, rather than by the
eneryating raethods of heated air or water.
" Since beginning this process, I do not find that
I am grown thin; and in my general health I ani
infinijtely better. I feel myself more strong and
active, and less sensible of cold. My diet has been
mach as usuai, but my appetite rather increased.
I bave occasionaliy taken a little bark to maintain
the general tone of the system ; and òn retuming
home after each walk, I bave found that a few
drops of harti^om in water were refresllìng, and
prevented thirst during the rest of the day.
520 A NEW MODE OF TREATMENT
* •
** By what I have leamt from very good authority,
the exercise I perform is not one-twentieth part of
t^rhat the Newmarket riders undergo. Hiere ìi*
hardly an example of one of those who follow the
advice of a skilful physicìan in their process of
wasting, that suffers by it; and the opinion that
either their health is injured or their life abrìdged,
is altogether erroneous. ' Excessive purging is ne-
ver used now, except when the riders are too lazy
to undergo violent exercise, for purging is found
by experience to be a much more prejudicial mode
of reducing their weight. Sweating by muscular
action with an increased quantity of clothing ibight
be recommended not only to rheumatic patients as
a saie and easy remedy for their pains; but to per-
sons of both sexes who are troubled with redundant
corpulency>
" P. S. Since the above was written, I have had^
leisure to make some further observations whìch I
teg leave to add.
*' I am stili more convinced thataveryprofuseand
long continued perspiration, promoted by muscular
action, is not ne«essary to the cure of rheumatism,
pr to the improvement of general health, unless
corpulency be one of the evils which is to be re-
moved. Perspiration may be useftd as.aproofthat
IN CHRONIC RHEUltATISM. S21
m
a very strong action is established in the system,
and may in some sort be regarded as the measure
of that action ; in the same manner as the point of
ebuUition is referred ta as a rough thermometer by
those who want very warm water. Of the very .
much which has been attributed to sensible and in-
sensible perspiration a great deal certainly is true ;
but may not much also be attributed to the action
excited in the system by those very medicines which
are supposed to promote perspiration ? Does mer-
cury, independantly of the diseases it cures or
causes, diminish the quantity of flesh by mere per-
spiration ?
" As an encouragement to those who might be de-
terred from the use of this remedy by the apprehen-
sion that it is too severe for a weak constitution, I
add the foUowing table of my weight taken twice or
thrice each day, during the time that I was per-
forming six of these sweating walks, (one in every
forty-eight hours) undertaken with a view to ascer-
tain whether the quantity of exercise necessary to
cure a sciatica, in such a case as mine, is so great
as to cause a ihaterial loss of flesh in the patient.
" Before I began to weigh I had already walked
nine times, It is therefore only by my general ap-
pearance that I can say I had not lost flesh by my
first walks. Previously to the six walks of which I
am going to state the results, I had been obliged to
suspend my exercise for fifteen days, as the weather

physician. A more valuable report, giving an ac-
count of both cases, has been recently presented to
the profession by ÌDr. Baillie, in the third volume
of the Transactions of a Society for promoting Me-
dicai and Chirurgica! Knowledge.
The conversation to which my communication
gave ijse, has induced me to ofter some observa-
tions'on the diagnosis, and treatment of a disease
which seems to be Uttle known, and which assumes
a more than usuai interest from its having proved
fatai to two physicians, notwithstanding their own
practical knowledge, and the aid of the most emi-
nent in the profession.
In ali the cases of cynanche laryngea, the mucous
membrane investing the epiglottis, glottis, an^
chiefly the extemal and posterior surface of the
larynx, was the seat of the inflammation, by which
the rima glottidi^ wàs so much narrowed, that the
vital functions were actùally extinguished by the
stricture. It is true that the tonsils, the arch of
the soft palate, the uvula, the tongue, the internai
membrane of the larynx and, trachea, ali, or seve-
ra! of them were inflamed ; but this was only an
extension of the action to one common membrane
which invests the whole, whilst it was most intense
at the mouth of the larynx. In both the cases
communicated by Dr. Baillie, uneasy sensations
were felt in the larynx. In one of them, tliis
symptom appeared at the accession of the inflam-

mation, and. strongly excited the patient*s anxiety
for the result, at a time when the apparent inflam-
mation in the fauces was so iiiconsiderable, that
upon a superficial observation it would hardly have
been noticed. I did not see Essex alìve ; but the
slight swelling of the uvula and tonsils which ap-
peared on dissection, n]ade it obvious that bis dis-
ease could not have been mistaken for cynariche
tonsillaris. In Case II, when I desired the patient
to point out the seat of bis suffering, he placed bis
fore-finger on the middle notch of the thyroid car-
tilage, to which the epiglottis is fìxed. The diiffi-
culty of the diagnosis does not in fàct He between
this inflammation and the cynanche tonsillaris, but
between it and the cynanche trachealis. Dr, Pit*
cairn wrote on a piece of paper, that bis complaint
pwas croup. Croup very nearly approaches the
cynanche laiyngea, but the difference between the
seats of the inflammation will appear by comparing
the symptoms and morbid appearances which be-
long to each disease. In the cynanche laryngea
the symptoms are, uneasy sensati on in the larynx,
difficult and painful deglutition, partial swelling in
the fauces, a supervening and perpetually increas-
ing difficulty of breathing, inflammatory fever. In
the cynanche tracheaHs there is a diflSculty of breath*
ing*, without any swelling in the fauces, or painful
deglutition, the expirations, especially in cough-

adjunct^ is of little importance. Many confoupd merely this
symptpm,
ing;, ^xe vfwry dirill, tfap fever is inflammatory. • In
both, the voice is ch^ged, and, in extreme c^tses^
is suppressed ; thje termination is by suffocation. —
The following are the morbid appearanceS : in the
former, the mncous membrane investìng the epi-
glotti^ and margin of the giottis is inilamed ;
serum is effiised under it, qr coagulabie ]ymph on
its extemal suriace, by which the rima glottidis is
narrowfed, or actually closed^ (See piate III.) In
thp latter, the mucous membrane of the larynx and
trachea is inflamed, and ajayer of coagulated lymph
is formed on its internai surface, from the extremity
of the epjglottis to an indefinite éxtent within the
trachea, by which the tube it&éif is narrowed, or
actually closed. A puriform fhiid, instead of mu-
cus, is found in the trachea and bronchia. These
charjj^cters chiefly apply to simple cases of both
species, for g,s they difFer in their seats, but not in
their nature, it is possible for both forms to he
combined in the same patient, and it were an easy
matter to prove that a stili greater extension of
inflammation than this does actually take place in
these organs.
In cprnparing the morbid appearances with the
symptpms of cynanche laryngea, it is not difficult
to determine that the inflammation, fron^ its limited

seay:, fram its not exceeding the bounds of the ad-
hesive stage, and from the symptomatic fever, re-
quires the use pf the lancet. I may be here allowed
to give an unbiassed opinion ; fòr in neither of the
cases which I bave described did I order general
bleeding : the first, I bave already stated, was not
attended by myself ; the second was not in ^ state
to adrait of tìiis remedy when I was consulted.
Both were bled, it is trae, but it was doife in the
very advanced stage of the disease. \^Tien the
function of respiration can scarcely be carried on,
the body will not then bear large bleeding ; but
although in the ultimate stage, the vital powers
are greatly depressed by the copious abstraction
of blood, yet on the accession of the inflammation
this remedy seems to be less a matter of choicé
than. of necessity. Dr. Pitcairn was bled once
cópiously on the third day, and died on the fourth.
Sir John Hayes was thrice bled, to the amount, in
the whole, of thirty or forty ounces, on the second
day, and died on the fourth morning. In both
these cases, it must be manifest to every one who
reads the history of them, that the patients died
not from exhaustion, but from strangulation. By
those who will take the pains to consider inflam-
mation as a process, it will be understood that it
may be checked, but cannot be suddenly extin-
guished by the most active means ; time must be
allowed for the process to deqline, even after the
fiiirest efforts bave been liiade to arrest its progress,
Unhappily, this necessary tim.e can rarely be ob«

tained in this disease, in which the activity of ^e
inflammation is expended on a smaU, but most vital
seat ; for the glottis once narrowed, may be closed
by the locai action, even after the general powers
are prostrate.
These sijmple, and, I trust, naturai views of the
subject, lead to a treatment which must be varied
according to the stages of the inflammation : the
first, or stage of congestìon, is the period for active
depletion ; on the accession of the disease, in the
first twenty-four hours, as soon as the patient feels
the slightest uneasiness in the larynx,, or a very
painfiil and difficult deglutition, which the appa-
rent state of the fauces cannot explain. There is
not in this stage any objection to copious general
bleeding, suited to the strength of the patient; biit
if this treatment fails to relieve, and the diflSculty
of breathing supei'venes, it is too certain that the
narrowing of the glottis has commenced. In this
second and alarming stage, or t^at of eftusion, it
may be proper to try locai blood-letting, by free
cupping from the neck and shoulders, and by a
continued oozing from numerous orifices made by
leeches on the throat. In both stages it is reason-
.able to resort to those internai means which dimi-
nish the force of the circulation in the capillary
àrteries ; and to produce this effect, none seem
better adapted than the combined powers of the tar-
tarized antimony and the submuriate of mercury,
in doses suited to the strength of the patient.
AND CYN ANCHE TRACHBALIS. S29
Jn the advancèd period of this second stage,
when the glottis is so much narro wed that the
signs of strangulation begin to appear, a persever^
ance in these or other ordinary means seem no
longer to aflFord even a chance of preserving the
life of the patient, his physician must now resign
him to the horrid death of slow sufFocation, or
make a last effort to save him by the operation of
bronchotomy. That the disease is a locai one^ that
it is acute, and of short duration, that it affects a
mucous «lembrane, which consequently does not
readily take on the adhesive inflammation, or if it
should be so acutely inflamed, easily sheds the
lymph that had been effused on it, are circum-
stances which, in the otherwise hopeless state of
the patient, justify a trial of this operation. But
if it be further considered, that bronchotomy has
actually preserved life under the more unfavour-
able disease of cynanche trachealis, the operation
becomes expedient. And bere I am happy to find
that the resort to bronchotomy, in Case IL is sup-
ported by the opinion of Dr. Baillie, who had ac-
tually proposed this operation in one of his cases,
which was only not performed because the surgeon
arrived too late. He also enforces this opinion by
the foUowing advice. " If no substantial advantage
is produced by this pian* in thirty. hours, it might

be advisable to perfbyrm the operatioa of broncho-
toHiy at the upper part of the trachea, just under
the thyroid gland. TKis operation would probabljr
euable the patient to breathe till the infiammatioa
in the larynx, more especially at the aperture of the
glottis, had tinie to subside."
Different parts of the windpipe bave been selected
ibr the operation by different surgeons» This seems
to me a matter of considerable importance ; but to
enter upon it would lead me Qut of my province.
It is more within the line of my duty to consider
what forms of cynanche admit of the operation.
In the cynanche maligna, the inflammatory action,
which is vehement, effuses coagulable lymph on the
tonsib, and, in the worst cases, on the mucous
membrane of the larynx ; but the strength of the
action is soon spent, the lymph perishes, and the sur-
faces which effused it die, and slough, or open into
ill-conditioned ulcers. In such a disease, if symp-
toms of strangulation supervene, it is almost need^
less to say, that bronchotomy is inadmissible, But
the badly ulcered or sloughing tonsils, with typhoid
fever, sufficiently distinguish this malignant disease
. from the simple cases which demand the operation*
In every uncombined case of cynanche laryngea,^
when otlier means bave failed, I think that the
patient ought to haVe the chance, even if it should
prbve a small one, which this operation aiFords»

proviiJg fatai, to the cynanche laryngea, that the
same mode of treatment, with a little modifìcation,
which is applicable to the one, is also suited to the
other. But when the cynanche trachealis is com«
bined with pneumonic inflammation, of whatever
kind, then the operation cannot avail. In propor-
tion as the infiammation is extensive, it is less in-
tense in the larynx, and I think it is not difiicult
to discriminate between the cases, at the period
when the operation is required, by the manner in
which thg respiration is conducted. In the one,
the difficulty of breathing is evidently that of im-
pending strangulation ; in the other, that of deep
seated and extensive oppression. The difference
may, perhaps, be illustrated better by a case of
each kind.

Williams, a fine boy, at the age of two
years and five months, was carried off by an acute
disease in little mone than forty-eight hours after
the attack. The distressing and violent symptoms
which markèd its progress, and the rapidity with
which it proved fatai, induced his mother to solicit
me to ascertain, by dissection, the cause of his
death. Previously to the examination, I minutely

violent and incessant cough, until the instniment was with-
drawn. A hollow bongie being introduced, produced the same
efJèct. I then contented myself with dressing the wound super^

openings into the trachea, and covering the wound with a piece
of gauze laid loosely on the neck'\

com^lsive and struggling eflforts with which it is
performed under a more complete obstruction of
the upper part of the windpipe, in cases of simple
croup, was striking. The child being of a vigorous
habit, and the inflammation acute, it was proposed
to draw six ounces of blood between the shoulders,

Mr. Newington communicated to me the follow-
ing parti culars : She was cupped, and in the even-
ing a doublé quanti ty of the mixture, ordered ili
the morning, was repeated at four doses, without
producing any^ other effect than great languor and
cold perspirations. The breathing continued to
be very laborious, but the cough was not so frc"
qu^nt. On Sunday moming, the 9th, before Mx.
Newington saw her, ber mother had given her a tea-
spoonful of antimonial wine ; she vomited a litde,
and in the course of the morning had three evacu-
ations from the bowels. In the afternoon the
antimonial wine was given in the dose of a tea-
.spoonful and a half without exciting vomiting. The
countenance, which was at first very florid, had
now become pale and languid j her palse had lost
its fulness and hardness. At seven in the evening
he found her a little easier, but very languid. Her
mother had administered, without bis order, a

been infused for that purpose. On Monday her

some ttìììk in a hurry, as if in danger of being
strangled. A squill mixt'ure was given, and
brought up some viscid mucus. In the eyening
the frequency of pulse and general languor had
increased, her lips were slightìy livid, but the rest
of the comitenance was pale, and about twelve
o*clock at night she died.

whiqh had also destroyed the pleura posteriorly,

from the lung, which, together with some of the
contents of the stomach, and probably some prìor
serous effusion from the pleura, made up the
quantity of fluid. The left cavity contained a little
serous effiision. A partial exudation of coagulable
lymph, on some parts of the surface of the pleura,
had made it somewhat rough, impairing that
polished surfaci3 which is naturai to the healthy
membrane. The pericardium and heart were faot
affected. The tongue, pharynx, oesophàgus, larynx,
trachea, and lungs were removed together. On
cutting open the windpipe posteriorly through its
whole length, its membrane was found besmeared
with a brownish mucus, under which it was every
where covered with a thin coat of coagulated
lymph, that extended into the ramifications of the
bronchia, (see piate VII.) but was no whQre in
sufficient quantity to dose the pipe : even in the
larynx the sacculi were apparent. The lungs had
suffered excessive congestion ; their parenchyma
was very generaljy red and tumid, yet they floated
when thrown into water. The effusion, therefore,
into their reticular texture was serous, but the
air-cells and minute ramifications of the bronchia
were loaded with a yellowish white fluid, the secre*

ali the tests hitherto used for that purpose. The
method consists simply in adding in succession, to
the fluid suspected to contain arsenic, minute
quantitìes of solutions of anamonia and of nitrat of
Silver j by which means, if the smallest quantity of
sirsenic be present, a dense yellow precipitata will
be prpduced.
Ali the particulars respecting this mode of de-
tection having been fuUy stated by Dr. Roget, with
such refèrences to former writers on the subject as

enter into any fìirther detail on this head. My ob-
ject in resuming the subject, the practical import-
ànce of which need not be pointed out, is to com-
municate to the Society the result of an inquiry
which I bave made on the nature of the yellow
precipitate, the appearance of which is assumed as
denoting the presence of arsenic, and to ànswer
sòme objections which bave been made against this
test by Mr. Sylvester, of Derby, in a paper on me-
tallic poisons, recently published in Nicholson's
Journal *.

it is inferred that its formation, when ammonià and

course be prevented from appearing,"
This danger of ambiguity, however, though
applying in some degree to the process in question,
and well deserving to be noticed, will be found to
bave been greatly overratedj and there are such
easy and obvious means by which this ambiguity
can be entirely removed, that it can make no solid
objection to the utility of the test.
There cannot be the least doubt, as Mr. S. obw
serves, but that whenever nitrat of silver is added
to a solution containing murìatic acid, a precipitate
of muriat of silver must be the consequence. But
if the nitrat of silver be added in excess, the ar-
senite of silver is also thrown down by the inter*
vention of ammonìa, and a . mixed precipitate c^
luna cornea and arsenite of silver is obtained»
which partakes more or less of the yeDow colour
of the latter, according to the proportion of the
two salts.
If to this dubious precipitate a few drops of di-
. Iute nitric acid be added, the arsenite of silver is
ìnstantly dissolved, and the muriat of silver,
which is insoluble, immediately resumes its pecu-»
liar density and whiteness. If a little ammonia be
now added to the clear fluid, the yellow precipitate
appears in the most distinct manner, and becomés
cyen more characteristic from atcomparison with
3

the white precipitate, the appearance of which
differs from this in evejyrespect.
By this method, I believe that every objectioa
to the test will be removed; and in order to anti-
cipate ali ambiguity, and to avoid any complica*
tion or practical difficulty in its application» I
would propose to modify the process in the fol-
lowing manner :
To the suspected fluid, previously filtered, add,
first, a little dilute nitric acid, and, afterwards,
nitrat of silver, till it shall cease to produce any
precipitate* The muriatic acid being thus re*
moved, whilst the arsenious acid (if any, and in
whatever state) remains in the fluid, the addition
of ammonia willinstantly produce the yellow pre-
cipitate in its characteristic form. It ìs hardly
necessary to add, that the quantity of ammonia
must be sufiicient to saturate any excess of nitrìc
jicid which the solution may contain.

posèd myself upòh one occasion, by getting out of
bed, and standing for some minutes subjected to
the night air at an open window, in consequence
of a quarrel in the Street, I was attacked, in a day
or two after, with acute ophthalmia in the left eye ;
which, however, was in a great measure removed,
in about a week, by the application of leeches, and
the use of saline purgatives. A slight degree of
obscure vision remained, from turgescence of the
vessels in the fore part of the cornea; butthis gra-
dually lessened, so. as, in a year after, to be scarce-

mination of another. A subsequent residence of
eight months in Bengal, during which I sufiered no
less than five attacks of severe illness, in the dif.

fevers, &c. not only radically impaired my general
constitution, but laid the foundation of that parti-

Durmg' the very severe wèather in January, 1789,
at whicH tìme the Thames was so completely frozen
afi to bare booths erected ùpon it, a heavy fall
of snow wasimmediately succeeded by a rapid thaw;
and the pipes belonging ta the house in which I
resided, being ali chokéd with ice, the snow water
io the leaden gutters of the roof, rose ^o high as to
get undet the tires, and made its way down tbrough
two floors, so as to come into the bed where I ky.
How long I was exposed to its influence ih the slow
oàode in which it descended, is impossible exactly
to say ; but when I awoke through the cold, I
found the feft side of my night cap, and my left
«honlder and arm, with tìie bed clothes covering
them, quite wet* After putting on a dry shirt,
éhifting the bed clothes, turning the feather bed,
and drawing the bedstead into another part of the
i?QOHf, Iwent to sleep again; andhopedthatnoincon-
venience would ensue, as I had more thanonce
been similarly wetted in my cot by sea-water, wìth-
out any bad consequence. In a few days, howevéf ,
I was attacked with ophthalmia in my left eye,
whick ptoved more severe and obstinate than any
preceding attack; confìning me three weeks to the
house, and nearfyaweek of that time to bed: even
when the continued pain was abated by leeches to
the check and tempie, foUowed by a blister, and
aiEed by purgjng, the vessels of the eye continued

iUstended with blood, and violent pains, affecting
not only the fore part of the eye, but extending ali
round the orbita carne on every night. Under
these distressing symptoms, I consulted the late
Mr. Hunter, who recommended the use of the cin-
chona rubra ìnfìised in lime water, which was at-*
tended by such speedy relief, that the very first
night after I began its use, I was quite free from my
usuai paroxysm of pain, and the eye instead of be^
ing dry and burning hot as before, now discharged
tears most copiously, which felt as cold as water
&om a spring. By continuing this remedy §or se-
veral weeks, I v^s enabled to go into the country
and settle in business; but I was for many months
distressed with inflammatlon of the glandulse Mei-
bomtì, the acrid secretion from which kept the tu-
nica adnata in a Constant state of irritation, and no
doubt served to fix stili more obstinately, a distinct
speck which had formed exactly in the middle of
the cornea, so as greatly to obscure the vision with
that eye for many years after.
From the period of this attack in 1789, I conti-
nued tolerably free from ophthalmia until the sum*
mer of 1 794, when I was visited by it in a stili
more formidable shape, about a fortnight after re*
covering from a smart fit of regular gout; fin: the
pain now was not confined to the fore part ef the
eye, but extended into the. interior, and at times
darted through to the back part of the head, with
$UQh violence as to resemble what I conceive woizld

so exquisitely seusible, that I could not bear the
smallest ray òf ligfat; and I could discern every ar^
ticle of furniture in a room so completely darkened^
that other persons were obliged to grope their way,
in order to avoid the table and chairs. Being tben
resident in a country town (Ketterìng) none of the
medicai men would undertake to open the temporal
artery, which I wa9 urgent to bave done, às I knew
that under such agonizing paìn, I could not long
retain my senses. I therefore dispatched a messen*
ger to Dr. Kcrr of Northampton, who was ludfily
met on the road, and very kindly hastened to assist
me. His opinion exacjiy coinciding wìth my own,
he immediately performed the operation, and took
away eìght ounces of blood before I became &int,
but even before half the quantity was drawn, I felt
my whole head relieved as from the pressure of a
vice, and the darting pains entirely subsided. From
that moment, I b^an gradually to recover, in eveiy
respect; but the sight of that eye stili remained ob*
scure, from the former opacity of the cornea; and
both ey es were at times Uablè to slight degrees of
redness and tenderness from exposure to cold.
In the spring of 1798, 1 underwent great fatigue
and anxiety, in attendance upon a gentleman for
wbom I had the highest regard; being three days
and nights, without taking off my clothes, or lying
down in bed more than an hour or two at a time^
On the very evening when I was liberated from this

feXertìonby the patient's death, I was seized^- in a
fe^ hours after getting home, with increased dim^
ness of sight in the left eye, followed bj violent
pain, which carnè on, with augmented severity, in
pangs that otcurred just àt the moment I was drop»-
ping to sleep. Having no other mode of relief at
band, 1 took a grain of opium with some antitaio^
nial poTC'der, by which I at last T)btained sleep^
and the next morning I felt my eye almost free
from pain, but with a particular sensation of ten*
demess upon the cornea whenever I moved the ey^
!ld over ìt. As the eye was nòw capable of hearing
the light, I examined it attentively by means of a
small looking-glass, and distinctly perceived a pit
or hoUow in the fore part of the cornea about the
sixth of an inch in breadth, nearly circular in form,
and exàctly corresponding with the place where the
speck or opacity was formerly situated, but which
now no longer appeared : in short it was evidènt,
that the speck had inflamed, and sloughed off dur-
ing the course of one night : the eye has ever since
remained free from any opacity visible to another
person ; but the new formed tunica adnata has not
the same fine polish as in the naturai and heaithy
state, and consequently small objects, such as the
letters in a hook, viewed with that eye^ appear hazy
and undefined in their edges, unless I look at tfaem
through a narrow chink, so as to defiect the rays
of light, and make them pa«s a little to one side of
the scabrous part ; in which way they ar« clear

Tbis detail may to some appear tedious and un-
iateresting ; but I thought it might be satìsfactory
to the Society, as it certainly would be to me, to
bave a complete history of the rise and progress of
a complaint, which subsequently displayed itself in
so disti net a shape, and with such severity of symp-
toms as I shall now describe ; being perfectiy con-
vinced, tliat nothing will contribute so much to en-
large our knowledge of^ pathology in general, as
that concatenation and sequence of phsenomena,
which at present are often considered as distìnct
disorders, though in fact only varìations of one
genus of derangementm the human system.
On Friday the 23d of Dee. 1802, after going
tound the hospital, and subsequently visiting some
private patients, I returned home ' at 3 o'clock in
order to dress myself for dining out ; but before
four o'clock, I felt so much stiffhess in my right eyey
that fearing the consequence of exposure in com-
ing back at night, as well as drinking any wine un-
der such threatening, I sent an apology, and de-
termined upon staying within doors ali the even-
Jng. By five o'clock the eye was become veiy stiff,
with some degree of soreness ; and só dim, that
the candles appeared duU, and surrounded by an
extensive halo or haze ; and at eight the paìn was
so considerable, that I could not read. I therefore
took at going to bed a grain of opium, tliree grains
of calomel, and two of antimonial powder ; after*
wards drinking a basin of water gruel to promote
pérspiratìon» I passed but ari indifferent night,
however; and in the moming, fìnding the eye-
considérably inflamed, I applied slx leeches round
the lower atìd outer part of the orbit; and took
gome colocynth extract, which operated 2 or 3
times with slight relief* In additìon to these mea-
sures, I put some of the vinous tincture of opium
(the old Tinctura Thebaìca of the London Fharma^
copoeia ed. 1 740) into the eye several tiriies, by
means of a large camiePs*hair pendi ; this occa-
sioned very pungent pain for a few «econds, and
was followed by a short abatement of pain, which,
however, was more comparative than real, for in a
quarter of an hour after, tlie eye felt no better
than before. At night the pain again increased,
and I repeated the opium &c. with relief, taking at
the same time some liquor ammonise acetatis to ex-
cite diaphoresis. The pain abated in the night,
and I got some sleep ; but no amendment appeared
next moming in the eye, which was now stili more
red than before* On the third night I blisteréd the
rìght tempie, and repeated the opiate, calomel, and
diaphoretic, without gaining any more than a tcm*-
porary benefit. On the fourth day, I became ex-
tremely alarmed by the increasing obscurity of vi-
sion, which was now so great that I could not dis-
tinguishthe barsof thewindow sash, and could bare-
ly count my fingers when held within a foot of my
face ; added to which, this was now not only in the
right eye which had never been more thaii
slightly aflfectcd before, but a similar though less

obscuiity, was making progress in the left eye also.
I therefore sent immedìately for an eminent sur-
geon-oculist, whom I will beg leave on this occa-
sion to designate by the name of myfriendy a name
to which his kindness and attention give him a just
claim. He carne tome soon after, and upon exam-
ining the eyes, remarked, that there was no opacity
in the cornea ; a circumstance which I had noticed
my&elf before his arrivai as difFerent from every for-
mer attack; though from the dimnessofmy vision,
I could not ascertain this so well as he did : I can-
not describe this peculiar state of vision better than
by saying, that every object which I could discern,
appeared of a dusky grey colour as if obscured by
smoke or steam ; and such as I conceìve would be
the case, if the aqueous humour of the eye had lost
its limpid transparency, and acquired the blueish-
grey tint, which I bave noticed in some minerai
waters. I held this as probably indicating an opa-
city of the capsule of the cristalline lens, or of the
vìtreous humour; and I could perceive from my
friend's mànner, that he had much doubt about my
recovery. I then stated to him the steps that I
had already taken, ali of which he approved of, éx-
cepting the opìum ; advising me by ali means to
abstain from it, às it would tend to weaken the ves-
sels of the eyes, and certainly retardj if not, in the
end, entireb/ prevenir them from regaining their na-
turai strength. However reluctant I felt, at giv-
ing up the employment of a medicine from which
I had found at least temporary relief, yet consider-

irig the disease as now altogether beyond my own
management, and having the utmost reliance upon
his judgment foundéd on long experience and ex-
tensive observation,- I determined to submit to
whatever measures he might think proper. As the
most ready means of lessening the extremely tur-
gid state of the vessels on the tunica adnata, he
proposed scarification ; which was immediately per-
formed, by drawing dowii the lower eyelid, and
scoring its surface in severai pkcés with the shoul-
der of a lancet, so as to take away about a tea-
spoonful of blood. No sensible relief attended
this operation ; . on the contrary, the clots of blood
which formed upon the incisions during the night,
acted like so many foreign bodies, and aggravated
the pain whenever the eye-lid moved upon the ball.
In addition to this, he recommended fbmenting
the eye with a decoction of poppy-heads, which
was accordingly employed, as soou as it could be
got ready. I had always found ease before from
cold applications ; and the present trial of an op--
posite temperature, concurred to strengthen my
fbrmer experience ; for the pain became so mucb
worse under the fomentation, that I could net con-
tìnue its use above a few seconds» Observing na
abatement of inflammation when he carne next day^
he conceived that the failure depended upon the
quantity of blood evacuated, being toosmall ta
lessen the congestion : and as a more adequate
depletion, opened the vein wlùch runs betwees^
the inner canthus of the eye^ and the aose, and

drew away a large tea-cupfoU of blood (about à%
ounces). During this operation, I thought my
head felt lighter, and the eye less stiff and full ;
but the relief did not last much beyond the flowing
of the blood j and the pain at night, with the red-
ness g,nd turgescence of the vessels next morning,
were exactly the same as before. My pulse being
nowlanguid as to strength , and unaccompanied either
by hardness in ìts stroke, or by febrile beat of skin,
he did not consider fartherloss »of blood, either ge-
nerally or topically, at ali adviseable; but recom^
mended a large blister to the head. I accordingly
had my head shaved without delay, and a blistering
plasterapplied over thewhole of thescalp,extending
fromone ear to another, andfrom the top of the forar
head to the nape of the ìieck. Notwithstanding
what might bave been expected from the imtation
^f so extensiv? a surface, I certainly slept better
than I had done for the three preceding nights ;
but this was ali the advantage it procured, as the
inflammation was not in the least diminished by it;
and the succeeding night was attended with the
same severity of pain as before. I now, agreeably to
his desire, took a quarter of a grain of the muriate of
quicksifver, dissolved in half an ounce of the spirit
of nutmeg, "and diluted with half a pint of warm
waterf^gruel sweetened to the taste. This excited
most profuse sweating for several hoors, and gave
me greater ease than any thiijg which had previ-
ously been done : indeed I had observed in former
j^nd s}ighter attacks, that sweating always proGure4-

relìef frolli pam, especially while the diaphoresis
was presenta I accordingly repeated the same me-
dicine on the foUowing night with veiy sanguine
expectations but by no means with equal success,
the pain being more severe aithough the sweating
was nearly the same. .The third night it failed en-
tirely ; and pwing to the nutmeg spirit then em-
ployed being made by uniting the essential oil
with proof spirit by triturating it with sugar, ìnstead
of distilling them together, the muriate of mercu-
ry was probably not completely dissolved, .in con-
sequence of which it occasioned considerable sick-
ness and vomiting : observing, however, that as
oftefa as I strained to vomit, though nothing was
brought up except the gruel, the pain of the eye was
sensibly lessened for a short period, I conceived
that fuller vomiting might be attended with stili
greater and more permanent benefit, and with this
view got to a medicine chest which stood in the
room, and guessing five grains of tartarised anti-
mony by lifting it between my finger and thumb, I
placed this in the palm of my band, and by wet-
ting the poìnt of my finger, took up what I supposed
raight be from half a grain to a graìn : I swallowed
this quantity every quarter of an hour, until I be-
. carne very sick, and vomited several times : after
which I gòt ease and fell ^sleep. Next day, the
eye appeared exactly as before j and feeling great
debility, and loss of appetite, I did not recur
either to the sweating or the vomiting pian. The
nocturnal exacerbation of pain having iigw become

grc^itly aggravateci, as well as more distìnclly
marked in its remitting form, I had recourse to the
cinchona, from which I had fòrmerly experìenced
such remarkable advantagej but although taken in
the same way, and in doses of a drachm every
&ur haurs, xt produced no sensible effect. One
article stili remained, which is known to possesa
extraordìnary powers in the cui'e of intermitting
fever, even where the Peruvianbark has feiled;
I mean the arsenjcal solution. This, therefbre,
I had recourse to, in doses of ten drops three
timesa day; but after two days* tiial, it occasioned
suchloss of appetite and of general strength, with-
put any perceptible advantage to counterbalanc^
these efiects, that I abandoned it as I had done the
rest.' I was now left, in the middle of the third
week, apparently wìthout any resource ; my sight
being only capable of distinguishing between day
stnd night y the flame of the candles upon the ta-
bìe appearing like two drops of blood, and the fìre
when buming bright, like a mass of red-hot iron,
whilst ali around was utter darkness : in addition to
which, the paroxysms of pain through the night,
could only be compared to screwing the eyeball
out of^ the socket ; and the only ease I had from
this, was by sitting up in bed, with a wash-hand-
basin of cold water placed between my knees, and
dipping a towel in this, which I applied to both
ey^s. Just so long as the sensation of cold lasted
(the ground was then covered with snow), so long
w:as the pain rendered bearable j but as soon as the
REMITTIN6 OPHTHAX.MIA, 361
wet tawel acquired a little warmth, the pangs re^
turned as before. Worn out hy suffering, and with
iJie melancholy prosppct of irremediable blindness
before me, I resolved to obtain ease at ali events,
by having recourse to opium ; and wishing to pro-
cure this more particulafly in the night, when the
pain was always wòrst, I took two grains of solid
opium at six o'clock in the evening/ I can scarcely
express the delìght I experienced on finding, that
instead of the paroxysm coming on between 7 and
8, as usuai, I felt quite easy ; and on going to bed
atten o'clock, gotinto a sound sleepfrom which I
awoke greatly refreshed and free from pain, at 8
next moming. The next day also, was compara-
tively a day of ease ; and it will readily be con-
cluded, that I did not fall to take the opium again
as on the precedingevening. The second night, like
the first, was a night ofbliss^ which was perhaps the
moreapparent, by my not sleepingat ali, but lying in
perfect ease. On the foUowing momìng, my friend
called, after an absence of two days (for indeed I
beKeve the obstinacy of my case had put hìs kind
attention to a severe trial by previous daily attendr
ance); and it was with unspeakable pleasure, I heard
him pronounce my eyes considerably better. I
then candidly stated to him, that the severity of
my sufferings had compelled me to disobey bis in-
junctions against taking opium ; and that, as I had
left off every other medicine except the occasionai
use of colocynth pili with calomel, as a laxatìve,
I could only attribute the amendment to the effect
362 REMITTINO OPHTHALMIA.
of that femedy. Under suqh circumstances, he
admitted, that I should continue its use ; observing,
however, that there was either something vety sin-
gular in the nature of the case, or that opjum wasi
peculiarly frien41y to my constitution. Notwith^
standing the strong proofs which I already had of
its beneficiai ipfluence, I was by no means firee
from fears, that in thus procuring temporary relief,
I might not ultimately do injury to my eyes ; and
believing that I had now in my power the means
of eifecUially checking the farther progress of the
disorder, 1 was determined to maintain my profes-
sional allegiance, by abstaining from opium until it
became imperiously necessary, Accordingly, oa
the third evening I did not take my dose as before
at six o'clock, but waited th^ coming on of the par-
oxysm, and though not without some anxiety, yet
certainly with greater hope, that I might either
escape the attack altogether, or bave it in a veiy mild
and bearable degree. At eight o'clock, I observed
the usuai precursor, a feeling of soreness, aggra-
vated by pressure, in the integuipents round the
eye, and especially at the infra and super-orbitari/
Jìoles, through which the nerves pass to supply these
parts. In twenty minutes the pain became very
severe^ and I immediately swallowed twograins of
opium. At nine o'clock the pain, instead of abat-
ing, was cvidently upon the increase ; I therefore
repeated the dose ; and having remarked that the
full effect of any individuai dose of this medicine
is generally experienced in three quatters of an
5
REMITTING OPHTHALMIA. 363
hoùr from the time of taking it, I deteririined to
repeat the same quantity every hour at farthest, un-
til relief ensued ; and as no sensible abatement
look place from what was previously administered,
I persevered at the assigned intervals, until I had
swallowed ten grains of soiìà opium, wlthout the
smallest alleviation of my sufferings. At twelve
p'clock, I became stupid to every sensation, except
that of agony ; and retired to bed in a state which
can better be conceived than described ; nor do I
exaggerate the deseription of my wretchedness
when I declare, that I should bave blessed the
fiiendly band which presented a pistol to terminate
my existence. FoTjòurteen hours aiid ahalf^ I lay
in this struggle between stupefaction and torture ;
the muscles of the right side of the face quivering
with pain as if tom from the bone, and a continued
stream of scalding tears running down the check,
whilst £he eyerball itself was, at intervals of only a
few seconds, afFected with a convulsion that made
every limb shake with the agony. At half past
eleven o- clock in the forenoon, the power df suf.
fering was itself wom out, and from that time till
five in the evening, I lay in a state which alarmed
the people in whose house I lodged, as I neither.
called for nourisliment^ nor even rang the beli to
say I wanted assistance of any kind. My convic-
tion, so dearly purchased, was now complete; and
ì resolved, whatever might be the ultimate event,
never to pass such another night, whilst I had the
pertainty of relief within my power. Aceordingly,

at six in the evening, I took three grains of opium,
with the satne happy efiects as at first ; and by re-
peating this every evening at the same hour, I not
only completely prevented ali recurrence of pain»
but in the course of ten days, was able to go out
daily in a carrìage to visit a patient at Canonbury ;
and at the end of three weeks, resumed my hospi-
tal business and lectures as before my attack.
Tlie case just related, offers grounds for much
new and interesting inquiry respecting ophthalmia
in general, and particularly that form of it which
has committed such ravages among those of our
soldiers and seamen who were employed in the ex-
peditìon to Egypt : as I am strongly inclined to
believe, that they bore a considerale resemblance
to each other in many essential points. At present,
however, I have no leisure for so extensive an in-
vestigation ; and were I even so disposed, 'I hayie
not had sufficient opportunities of seeing the
Egyptian ophthalmia as it has been prolonged or
propagated in this country, to qualify me for such
an undertaking.
One circiunstance has surprìsed me greatly,
which is, that in the course of a pretty extensive
examination of authors, both ancient and modem,
which I have been obliged to go through in order
to coUect materials for my lectures, I have not met
any case resembling my own. Does this proceed
from its being unique in its kind, or from want of

due discrìmination in those who bave treated on
ophthalmia, especially in its epidemie form ? How*
cver reluctant to admit the lattei conclusion, yet
I am compeiled to do so when I aiHrm, that, not-
wìthstanding the almost exclusive treatment ofsuch
complaints by the oculist, and the consequent in-
frequency of their coming under the cognizance
of the physician, I bave myself met witb several
of the same kind ; and, therefore, reasonably pre-
sume, that I am not the only person to whom they
bave occurred. Being bereditarily of a gouty con-
stitution, and bàving bad to the amount of six m
seven severe and regular attacks, beside many
sligbter and irregular pnes, it might be ìmagined^
especially as gouty opbtbalmia is mentìoned by a
few authors, that mine was of that descrìption ;
and such indeed was the opinion of the friend who
attended me; as be acknowledged, that on no
otber ground could be account for the disorder
giving way to opium, wbile it resisted every mode
of treatment which be had before found successfiiL
At first I was disposed to admit this reasoning ; but
from subsequent attention to the disease, as it bas
occurred both in myself and in otbers, I am satis-
fied that it is not correct : for three of the cases
which I bave seen besides ray own, were in females
who are well known to be very rarely the subjects
of gout, comparati vely witli men ; and in no gouty
attack which I bave ever bad in the inflammatory
form, did I ever receive any considerable relief
from opium. The progress^ likewise, of the two
866 REMITTING OFHTHALMtA<
forms of disorder is very different ; for I hàve hié
gouty paroxysms of varìous intermediate duration
between ten days and six weeks, whereas the oph-
thalmia in three distinct attacks posterìor to the
one related above, has regularly assùmed the f ebrile
perìod of three weeks^ so raarkedly so indeed, that
in three of a milder degree which occurred in
1806, 1810, and 1811, although by the use of
opium I kept the disease so completely in check,
as not to be confined from my business a single day,
yet it ran its usuai period. But a very curious
circumstance yet remains to be mentioned, which
will, perhaps, of itself be sufficient to disprove the
alledged gouty nature of my ophthalmia in 1802-».
It must be remembered by most of the Members
of this Society, that themonth of January, 1803,
was that in which a very violent, and in many in*
stances fatai, catarrhal pneumonia prevailed in
London and its environs particularly, but I. beh ève
also, though in a less degree, in every part of En-
gland. The same disease had previously appeared
in some part of Germany, whence it spread to Pa-
ris, where it raged with unusual violence under the
name of la gripe ; and it had begun to decline at
Paris, about the time it arrived at its gi^eatest heighf
in London. From the date of the memorable in-
fluenza of 17825 which was perhaps the most uni-
versai ever recorded (having traversed the earth in
a westerly direction, fbom the Tartar hords con-
tiguous to the Great Wall of China, and finally
spent itself in the West India Islands and Americo,)
B£MITTÌNG OPHTHALMIA. 867
t had never escaped an epidemie catarrh in its or-
dinary form, until this time. My escape on this
occasion may indeed be accòunted for, upon a
prìnciple which, though not universa!, is yet so
general as to be admitted atnong the laws of the
human constitution, vìz. that one disease super-
sedes, or prevent» another of an analogous nature,
from taking place at the same time; and it w31
readily be granted, that my constitution was suffi-
ciently occupied by one kind of suffering, to en-
title me to an immuni ty from any other as long as
the first continued. But will this, as applied to
any case, explain why the same freedom from ca-
tarrh should equally attend nmny other persons who
were afiècted with ophthalmia about the same time
as myself, although in so trifling a degree, as scarce-
ly to confine them to the house ? Mr. Stocker, Apo-
thecary to Guy's Hospital, and several of his fa-
mily, had slight ophthalmia during the pre-
valence of the influenza ; but not one so a£Pected
had any attack of catarrh. A person who carne
to me on business during my convalescence, ob-
serving that I wore a shade and green spectacles,
told me that he had been himself a sufièrer, about
three weeks before, with the same complaint in his
eyes, as had many of his neighbours, aiid of his
-workmen ; and upon inquiring whether he or they
had also the influenza, he said it had been remarked
i>y alias surprising, that they escaped the epidemie
cold. During the summer of 1803, I met Sir
Jan^es £ellow93, who had lately befor? retumed
368 HEMÌttÌNG Ò^HTIiALMlÀ.
from Paris, whére he was during the whole time that
h gripe prevailed j and Upon mentiomng to him
the singular connexion between it and ophthalmia
in London) he informed me, that a similar coinci-
dence was noticed ih France, with this unac-
countable difference however, that there the ca-
tarrhalpneumonia j?rec^flk(S?the ophthalmia 5 butthat
the immunity Was the sàme ih bóth places, no per-
son who had laboured under ta gripe being known
to sufFer afterwards from inflammation of the
eyes ; Dr. M^Donnell, of Orchard Street, Portmatì
Square, whò was likewise in Paris at the period re-
ferred to, confirmed by his testimòny the informa-
tion of Sir J. Fellowes, both às to the ordèr in which
the two forms of complaint took place, and to the
exemption which each of them affi>rded against the
other.
The evidence which I bave bere adduced, will
perhaps be deemed by. the Sopiety quite sufficient
to decide the qhestion in the negative, as to the al-
ledged gouty nature of the ophthalmia; butwhat-
ever doubt might remaìn on that point, it must be
ientirely done away by the account I shall now give
of my last attack, which I watched most minutely
through its several stages, with a view to place this
circumstance beyond controveri^y ih. future.

dìeinde at the distance of four days, so that I Was
enabied to go about, though stili with ìnflamma^
tion, swelling atid pain ; and at the end of a month
from the commencemènt, the symptoms spentane-
ously ceased, leaving me in better general health,
than l' had been fbr a considerable time» Durìng
the latter part of May, though able to walk very
well, I was prevented by the coldness and wetness
of tìie weather, fronì taking any exercise on foot,
which is the only kind that is eifJier pleasant or be-
neficiai to me, On Monday the 4th of May, the
weather became suddenly mudi finer than it had
been for many wéeks, and I determined to avail
myself of the change, by dismissing my carriage in
Oxford Street about three o'clock, and doìng the
remainder of my business on foot. The sky was
perfectly free from clouds, and the sun considera
ably hot ; but the wind was easterly,. and had a
bleak chillness in it which made the alternate sen*
aations of beat and cold, accordingly as I was in
the sunshine or shade, peculiarly unpleasant. In
passing* along Heet Street on my return home^
about fivtt o'clock, I felt suddenly a painful sensa<>>
tion in the lower part of my right eye, exactly as
if a person had forcibly thrust the end of their
finger against the under eye-lid; and as this took
place not only without any obvious cause, but as
the dull pain continued, though in a less degree»
during the .remainder of the evening, I had no
doubt but it was a prelude to a severe attack of
ophthahnia. As soon as I could examine the eye^
VOI-. III. JB b
I foTlnd my alarm was but too well grounded^ fot
there appeared a stream, as it were, of red vessels
running from the lower part of the eyeball to the
edge of the cornea, exactly at that part where I
had felt the paìn at first. I lost na.time in taldng two
gralns of opium, which procured me a very good
night i and as the eye was scarcely at ali painfttl,
and had become but very little redder when I
looked at ìt again the next moming, I flattered my-
self that I shonld escape without much ìnoonvexiì-
enee. When the evening caule, however, this hope
was done away, as the pain recurred, and compdied
me to take three grains of opium to get relìe£
The foUowing morning the eye was very red, and
the sight £0 obscure^ that I could scarcely read a
letter. As the treatment difiered in no i^i^ect
from that which I bave already detailed^ it is nn*
necessary to repeat it here; suffice it (to say, làat
by pursuing the same pian now^ I was not kepi
within doors more than three days, and these luri;
in succession ; for afìter staying at home on Thurs-
day and Friday^ I felt so much better on Saturday
that I made a number of visits, and in the evening
ftént to apprize my fnend Dr. Babington, who was
lecturing fòr me, that I should resumé my hosj^tal
duties on the Monday. Very early on Simday
morning, however, the pain came on with great
violence, so much so indeed, that it required mx
grains of opium taken within the first hour, to
render it bearable j and eìght grains more, at
difierent periods through that day, to keep it off.
SìEMiTiPtNG aTwrUAlmÀd S7i
In tte course of the succéeding weèk the inflam*
matìon abated^ and a second timé did I§ at the
distance of seven days, ànnounce my intention of
retuming to leeture j but a second time wàs I dis*^
appoìnted, by the vessek of the eye becoming
stili more disterided^ though Hot more paitlful than
before ; and the vision with that eye being as
much obscùred as in the attack of 1 802-^3. At the
end of the third week the pain ceased entìrely, and
the redness abated so fast, that in four days more
I returtied to the discharge of my several dutìes as
before my attack*
The complaintj in this ìnstance, clifiéred £rom
that of 1802->S in two partìculars^ viz. that the
diumaì exàcerbatìon of pain was not so great as it
was then, whilst the septenary or hebdomàdat stages
Were much more distinct; in which respect the
first partook more of the ìnt^mitting, the lattea
moi^e of the contìnued febrile type^
