SIR CHARLES MANSFIELD CLARKE, BART. 

MJ>^ F JUS. 



Mt dear Sm Charles, 

The dayi are gone by when dedications could be relied on 
as passports to public favor ; but I hope it will never be out of fashion to 
make a public profession of gratitude, esteem, and respect. I am proud to 
acknowledge myself as your pupil, and to avow that from you I learned, 
not only the science of physic, but the art of lecturiiig. 

The position which you occupy in society sufficiently attests your skill 
and acquirements ; but the esteem and regard of your brethren, which no 
one ever enjoyed in a higher degree, have been earned by still higher 
qualities of mind, by great urbanity, and an untiring readiness to promote 
the professional advancement of your juniors. 

I have yet another reason for prefixing your name to these pages. They 
treat of diseases which occur for the most part in that early period of 
human life, to the management of which your thoughts have been in a 
great degree directed. In submitting my ideas to your judgment, I feel that 
I am subjecting them to their severest ordeaL 

I am, my dear Sir Charles, 

Ever very faithfully yours, 

GEORGE GREGORY.

PREFACE. 



The following short course of Lectures on the Eruptive 
Fevers was delivered in the Theatre of St. Thomas's Hospi- 
tal, between the 18th January and the 8th February, 1843. 
It was thought that the experience which twenty years of 
official connexion with the Small Pox and Vaccination 
Hospital had given to the author might contribute something 
towards that extended and improved system of medical 
education now pursued in that school. 

The Lectures are published in the same form as that in 
which they were delivered, with the exception of certain 
portions necessarily omitted in the oral delivery, in order 
that what was calculated for thirteen lectures might be com- 
pressed into eleven. 

The author is very conscious of one imperfection of the 
present volume. He is fully aware that the conversational 
tone adapted for the lecture-room does not suit the closet so 
well as the gravity of a didactic style ; and that many, who 
might be inclined to look with favor on the matter, may 
very reasonably object to the manner. 

The author would anticipate one other criticism. Those 
who are in possession of the " Library of Practical Medi- 
cine " will at once perceive that a chapter in the first volume 
of that work has here been laid heavily under contribution ; 
but as, in so doing, the author only borrows from himself on 
points where later experience has suggested no improvement, 
he trusts to obtain the kind indulgence of the reader. Should

of the four epidemic diseases, small pox, measles, scarlet 
fever, and hooping cough, in the cities of New York, Phila- 
delphia, Boston, Providence (R. I.), Lowell (Mass.), Baltimore, 
and Charleston (S. C), and in the State of Massachusetts, as 
could be obtained ; and also some more extended remarks on 
various topics treated of by the author, which the editor 
considered more appropriate to this portion of the work. 

To enhance still further, as was hoped, the interest and 
value of the work, plates of the vaccine disease as it appears 
in the cow and on the hands of those inoculated from this 
source, copied from the beautiful and faithful illustrations of 
this affection by Mr. Ceely, of Aylesbury (Engl.), in his work 
on the varioleB vaccinae, have been annexed. 

The editor is happy to acknowledge the aid which he has 
received in constructing his statistical tables from the valu- 
able labors of Dr. Emerson, of Philadelphia, Dr. Joynes, of 
Baltimore, and Dr. Parsons, of Providence. The other and 
principal items in the tables have been derived from public 

documents.

LECTURE L 



CHARACTER AND AFFINITIES OF THE ERUPTIVE 

FEVERS. 

Mutual relation of diseases. Importance of the skin in the animal economy. 
Varieties of cutaneous disease. Exanthematic mortality throughout Eng- 
land, and in the metropolis. General character of the exanthemata. Of 
exanthematous fever, its uniformity and steadiness of course. Fever not 
essential to exanthemata. Symmetrical disposition of exanthematous 
eruptions. Alleged identity of the exanthematic poisons. Law of sus- 
pension. Affection of mucous surfaces accompanying exanthemata. 
Structures secondarily implicated. Variety and occasional severity of 
such complications. 

If there be any group or class of disorders which admits 
of being considered apart from and independent of 
others, it is undoubtedly that association of complaints 
called the exanthemata, or eruptive fevers. The reason 
is this. There are many pathological principles which 
are best exemplified in the phenomena of the exanthe- 
mata, and some which are nearly peculiar to them. 
Nevertheless, while I acknowledge this, I would at the 
same time impress upon you the great principle, that 
there are no diseases strictly isolated fi^om others ; they 
are links in a chain — 

" All are but parts of one stupendous whole .^' 

They must be viewed in conjunction, if we would hope 

1 



2 MUTUAL RELATION OF DISEASES. 

to form just, enlarged, and legitimate views of the cha- 
racter and pathological affinities of each. 

Let us ask ourselves, what would be the conduct of 
a judicious traveller, when he first sets foot in an inte- 
resting district of country ? Would he not lofik out 
for some elevated point, some pinnacle or cloud-capt 
tower, from whence he may survey the general aspect 
of the country, trace the course of the rivers, and the 
direction of the mountains, — from whence he may note 
how the district is indented, on the one hand, by the 
countries he has already traversed, and how it loses 
itself, on the other, in those portions of the country 
which he has still to explore ? 

That which would be a pradent course iq the tra- 
veller would be an equally prudent course with us. You 
have studied some portions of the great field of patho- 
logy ; others remain for future investigation. Let it be 
our business now to take a general view of the exanthe- 
mata, in relation to other branches of patholc^ical 
study. It can be but a bird's eye view that I lay 
before you, but such a sketch, loose and imperfect as it 
must necessarily be, will prove useful to us, I had 
almost said essential, in the further prosecution of our 
design. 

Let us, then, consider the relation in which the 
exanthemata stand, 1. to each other; 2. to other forms 
of fever ; 3. to other diseases of the superficies ; 4. to 
other diseases arising from morbid poison ; 5. to the 
diseases of other structures. 

On the structure of the skin, or dermoid tissue, I 
have no intention to enlarge. That subject has been 
already brought before you in the lectures of Mr. 
Grainger. You will remember what was said of the 



PlIVaiOLOGY OF THE SKIN. 

epidermis, of ihc corion or true skin, and of the rauci- 
form tissue, called rete mixcosam, interposed between 
ihein. You will bear in mind what you were taught 
regarding the blood-vessels and nerves of the skin. 

But though I shall pass over in silence the anatomy 
of the skin, I must detain you for a few minutes while 
I direct your attention to some points in its physiology. 
The skin, yon know, is the great organ of transpiration. 
By means of tlie skin, the body loses every twenty-four 
hours not less than thirty ounces of matter, — very nearly 
two pounds. 

[Very Uifferent results have bceii arrived at by tbose who h«ve made 
experiments for the purpose of nacprtaining the amount of nmlter 
thrown off from the skin. M. Seguin fixed the quatiOly, taking the 
aventge of his experiraenla, nt eleven grains per minute, in a grown 
penQii, or more than two pounds in tweutj^-four houre. 

Dr. Willirtm Wood, of Newjiort (England), makca it abf<ut forty-fivti 
ounce*, or nearly four pounds every twenty-four hours. (Eniag on 
Structure anil Fanetimu nf Skin. Edinb,, 1832 : quoted by Dimglisoii. 
PhysiolosTP. 1850.)] 

The skin is exposed to the atmosphere, and to the 
moisture which the atmosphere contains, and to all its 
other inflnencps. It must he, and it is, fitted to bear 
the extremes of temperature which the meteorologist 
registers. You are aware that there are at least a 
hundred degrees of difference between the iicals of 
Calcutta and the snows of Caubul. Tlio skin, too, 
is exposed to various injuries, for by the sweat of 
man's brow he is to earn his daily bread. It is also 
supplied with abundant means for the repair of those 
physical injuries. Its numerous blood-vessels are 
endowed with a strong disposition to heal by the first 
intention (adhesive inflammation), or failing that, by 
the second intention, bv which is understood the pro- 
cesses of abscess, granulation, and cicatrization. 






4 VARIETIES OF CUTANEOUS DISEASE. 

If you wish to satisfy yourselves of the unmense 
importance of the skin in the animal economy, observe 
the effects of bums and scalds. See how a severe bum 
affects the heart, and the brain, and the lungs ; I may 
now say, also, the duodenum ; for the inquiries of Mr. 
Curling have lately added this viscus to those which 
severe injury of die skin disturbs and disorganizes. A 
man may lose one half of his lungs by slow ulceration, 
and he may yet live for months, nay, for years. But if 
one half, or one third, or even one fourth of the skin of 
the body be destroyed, the system rapidly gives way, 
and death ensues. 

The skin may be considered as the fourth in the 
series of important organs. First come those of the 
enceplialon, then those of the chest, then the abdominal 
organs, and lastly, the superficies. This portion of our 
frame, the superficies, is subject to various diseases 
originating from internal and obscure causes. They are, 

1. The acute febrile affections bringing life into 
hazard. We call them the Exanthemata, from the 
Greek av^o^, a flower. Hence egav^^w, to bud forth or 
effloresce. Of these greater exanthemata there are 
four: — Small Pox, Measles, Scarlet Fever, and 
Erysipelas. 

2. The acute febrile affections not bringing life into 
hazard, — the lesser Exanthemata. They are divisible 
into two sections. 1. Vesicular affections, of which 
there are four: — Vaccinia, Varicella, Herpes, and 
Miliaria. 2. The simple efflorescences, not leading to 
fluid effusion ; of which there are also four — namely, 
Lichen, Urticaria, Roseola, and Erythema. These 
twelve forms of eruptive fever will constitute the sub- 
jects of the present series of lectures. 

3. The chronic cutaneous affections of a mild or 



EXANTHEMATIC MORTALITT. 5 

benignant character, formerly characterized as being 
boni moris : such as Lepra, Psoriasis, Ichthyosis, Impe- 
tigo, Elephantiasis, and MoUuscum. 

4. Chronic cutaneous affections, mali mo7'is, bearing 
a malignant character, such as Cancer, Lupus, and 
Fungus haematodes. Complaints of this latter kind are 
exclusively surgical. The physician is consulted in all 
the others. 

I have said that the greater exanthemata are those 
which bring life into hazard. The first point, there- 
fore, to which I have to call your attention, and which 
strikingly displays the relation of the exanthemata to 
each other, is exanthematic or epidemic mortality : 
what is its amount 1 — what proportion do deaths by the 
exanthemata bear to the deaths by all other diseases ? 
Is this proportion constant or fluctuating ? Is it alike 
in town or country t I will tell you. 

Upon an average of years, 350,000 persons die 
annually throughout England and Wales, and 46,000 
in the metropolis. The mortality by the four great 
epidemic maladies (small pox, measles, scarlatina, and 
hooping cough) is very nearly 40,000 in England and 
Wales, and about 5000 in the metropolis, averaging 
one in nine of the total mortality, or eleven per cent. 
This is a very large proportion. That four diseases 
only should absorb one ninth of the total mortality of 
this and probably of all other countries, may well excite 
our surprise. 

[The average mortality by these four great epidemic diseases in 
New York, during the forty years from 1806 to 1845 inclusive, was one 
in about thirteen (12f) of the whole mortality, or nearly eight per 
cent., and in Philadelphia, during the thirty years from 1816 to 
1845 inclusive, one in thirteen and a half, or seven and one third per 



\ 



EXANTHEMATIC MORTALITY. 



cent. Iq both these cities, the proportion was one third more during 
the last two decennial periods (from 1826 to 1S35) than during the 
period from 1816 to 1825. In Boston, the deaths by these diseases 
from 1831 to 1840 inclusive, amounted to one in nearly nine and a 
half, or over ten and a half per cent., and from 1841 to 1845 inclusive, 
one in about eight, or a little more than twelve per cent. See Table 
A in Appendix.] 

If the exanthemata are considered independent of the 
hooping cough, considerable fluctuations will be per- 
ceived, the mortality by them falling sometimes as low 
as six per cent., at times rising to near thirteen ; but a 
very important principle comes into play here, which 
serves to equalize the amount of epidemic mortality. 
This curious doctrine had long been surmised, but was 
never proved until the statistical inquiries of recent 
times showed its correctness. We may, for want of a 
better name, call it the law of vicarious mortahty, by 
which is understood, that whenever one epidemic 
diminishes, another increases, so tliat the sum total of epi- 
demic mortality remains, on an average of years, nearly 
the same.' The following table exempUfies this : —

EXANTHEMATIC MORTALITY. 



We learn from this table, that every year is dis- 
tinguished by some master epidemic. In 1838, small 
pox was the ruling epidemic throughout England. In 
1839, measles and scarlet fever struggled for the mas- 
tery. In 1840, scarlet fever was so general, and so 
fatal, that the mortality by it exceeded by one fifth the 
ravages of small pox during an epidemic season (1838), 
and more than doubled the mortality by that disease in 
1839. 

The following table, exhibiting die amount of epi- 
demic mortality in the metropolis during a period of 
five years, shows that the same general principle applies 
to town and country, but is less manifest in the smaller 
population.

From this table we learn that in 1838 small pox was 
the great epidemic in London as in the country. In 
1839, measles and scarlet fever were both on the 
increase, while small pox had sunk from 3817 to 634. 
In 1840, scarlet fever predominated. In 1841, hooping

cough doubled its numbers, and shot above all the rest ; 
while scarlet fever sank to the low point which small 
pox had reached in 1839. The year 1842 has been 
remarkable, first, for the extreme infrequency of small 
pox, one death only throughout this great metropolis 
being attributed to it for each day of the year ; and 
secondly, for the uniform rate of mortality occasioned 
by its three great rivals. 

pn Appendix B, will be found tables showing the amount of 
epidemic mortality in the cities of New York, Philadelphia, Boston, 
Providence, Lowell, and Charleston (S. C), and in the State of Massa- 
chusetts (exclusive of Suffolk County), during different series of years in 
the different cities, from 1805 to 1849 inclusive. 

It may be seen by reference to these tables, that scarlet fever was the 
predominating disease in the first three of these cities during the five 
years referred to by our author, except in Philadelphia during 1841, 
and in Boston during 1840, in both which years small pox exceeded it 
in mortality — tliat small pox increased nearly four-fold in New York in 
1840, and in Philadelphia in 1841, and nearly two-fold in Boston in 
1840 — and that in 1838, when it was the great epidemic in London, 
the* whole number of cases in New York and Philadelphia was only 
about one third of that of scarlet fever, and in Boston only 3 to 106 of 
that disease. 

It will also be seen that there was a great increase of mortahty by 
small pox in New York in 1834, '5, '6, "7, and in Philadelphia in 1833, 
'34, while there was no epidemic visitation of it in Boston until 1839. 

In New York and Philadelphia, scarlet fever predominated in 1840, 
as it did in London ; while in 1841, hooping cough was less prevalent 
in each of these three American cities than the other diseases, consti- 
tuting in Philadelphia a proportion of only 6 to a total epidemic 
mortality of 407 ; the next year, however, in the same city, reaching to 
197 out of an epidemic mortality of 697. 

In Baltimore, small pox and scarlet fever were both rife in 1838, 
and the latter was the predominating disease until 1842, during which 
year measles took the lead. 

The same fact with regard to both scarlet fever and measles will be 
found in Charleston, the former prevailing extensively in 1838, when 
the number of cases of measles was only about one seventh ; while in 



EXANTHEMATIC MORTALITY. 9 

1842, the number of cases of scarlet fever was just one half that of 
measles.] 

Everything teaches us that when one avenue to death 
is closed, another opens, — 

Noctes atque dies patet atri janua Ditis. 

You will perceive from all this, that vaccination, 
great as its merits are (and no one more fully appre- 
ciates them than I do), does not, and cannot do all that 
its too sanguine admirers promised. The blessings of 
vaccination are met and counterbalanced by the law of 
vicarious mortality. How and why is this? The 
explanation is easy. The weak plants of a nursery 
must be weeded out. If weakly children do not fall 
victims to small pox, they live to fall into the jaws of 
tyrants scarcely less inexorable. Scarlet fever and 
measles are both advancing in respect of mortality, and 
the increase of deaths by hooping cough since this 
century set in is quite extraordinary. 

These statistical considerations are both curious and 
instructive, but they are not to diminish our zeal in 
behalf of vaccination, or our efforts to lessen the sum of 
human misery. 

[The subject of vicarious mortality is one of much interest, and one 
which has not received the attention it deserves. Statistics prove that 
the per centage of deaths under five years of age is rather on the 
increase than the contrary, in cities at least ; or, at any rate, remains 
about stationary, and that at a high point in the scale, notwithstanding 
the many lives acknowledged to have been saved by vaccination ; and 
it is no less true, that the mortality by scarlet fever, measles, and 
hooping cough has increased, both in this coimtry and in Europe, 
within the last twenty years. 

It must necessarily be the case that the lives saved from small pox 
increase, by just so many, the number of those who are exposed to 
other causes of death ; and if the susceptibility to each exanthem be the 



10 CHARACTER OF THE EXANTHEMATA. 

same, the balance of life among those who suffer most by these dis- 
eases would naturally remain the same, so far as this cla<*s of causes is 
concerned, supposing them to prevail with equal fatality at all times. 
But other elements must enter into the calculation. The diminution in 
the number of victims of small pox and the increase of mortality by the 
other exanthems, at any particular period, will be governed also to a 
certain extent by the absence of epidemic prevalence of the former, and 
the existence of such a prevalence of the latter. It is, therefore, neces- 
sary to examine the subject in several points of view, and also to extend 
the investigation over a long succession of years, before conclusions 
deser\nng of confidence can be reached. Even a limited view of the 
subject would require more space than could with propriety be devoted 
to it in this connexion, and we reluctantly dismiss it with this passing 
notice.] 

Dr. Haygarth once inquired what would be the pro- 
bable effect of a complete annihilation of small pox. 
He entertained some extravagant idea of effecting this 
by a plan of universal inoculation. The result of the 
calculation was, that in fifty years more than one eighth 
would be added to the population. On a population of 
sixteen millions (which we now nearly reach), the 
increase in fifty years would therefore be two millions 
and a half. In this calculation, the doctrine of vica- 
rious mortaUty, though not left out of consideration, 
was, it is plain, prodigiously underrated. 

The general character of the exanthemata is derived 
from the following sources : — 1. From the presence and 
course of the accompanying constitutional disturbance. 

2. From the course of the local or cutaneous affection. 

3. From the law of universal susceptibility. 4. From 
the law of non-recurrence. 5. From the law of con- 
tagious origin. 6. From the law of epidemic diffusion. 
Fever, eruption, universal susceptibility, non-recurrence, 
contagion, epidemic diffusion — these are the topics 



CHARAOTER 01* THE EXARTBEHATA. 

which in the course of this and the succeeding leclure 
are to occupy our thoughts. They will be found to 
involve a great variety of ioiportaut and some very 
carious considerations, ail equally necessary to a due 
understanding of the exantliomata. 

]. The exantlieniata are usually described as fevers 
to which eruption is essentially linked. The old 
authors used ihe phrases febris variolosa, febris ruheo- 
losa, febris anginosa, and eryslpelatosa, wheu speaking 
of these disorders. As the doctrines of fever have not 
yet been formally explained to you, I may premise that 
by fever we mean a general disturbance of the whole 
system, affecting principally the heart, lungs, brain, and 
secreting organs, but extending, more or less, to every 
structure and function of the body. The four leading 
features of fever are — 1. Rigors, succeeded by or alter- 
nating with flnslios. 2. Frequency of pulse. 3. Las- 
situde and debility. 1. Diminished and depraved 
secretion. Wheu a man has a hot skin, a frequent 
pulse, a furred tongue, and a feeling of weariness, we 
say that he has an attack of fever. The lesser symp- 
toms are, restlessness, disturbed dreams, wandering 
pains, especially of the back aud limbs, tlnrsr, and loss 
of appetite. 

Fever is of several kinds, types, or characters. We 
distinguish four great types of fever, the inflaunnatory, 
the nervous, the gastric, and the malignant, in which 
respectively the heart, the brain, the intestinal canal, 
and the blood itself are more directly and severely im- 
plicated. The true character of exauthematons fever is 
innammatory. This it exhibits in nineteen twentieths 
of the cases of small pox and measles. The low or 
nervous form offerer occasionally characterizes scarla- 



J 



12 EXANTHEMATOUS FEVER. 

tina and erysipelas. The putrid, petechial, or malignant 
form of fever is occasionally witnessed both in small 
pox and scarlatina. In these cases the blood is literally 
poisoned. It loses its ordinary powers of coagulation, 
bursts through its containing vessels, and appears in the 
form of petechiae and haemorrhages. It is a curious 
circumstance that the vaccine poison, mild as it is to 
the greater number of mankind, may yet in the same 
manner poison the blood. I have lately attended a 
case of petechial cow pox — an occurrence hitherto 
unrecorded. It is far from an improbable supposition, 
that in the worst of these cases the vitality of the blood 
is actually destroyed, and that death takes place in 
consequence of the circulation of blood, the vital pro- 
perties of which are extinct. 

Exantliematous fever is divided into stages. I shall 
have to speak to you of four stages — the incubative, 
eruptive, maturative, and secondary. The incubative 
stage, commonly called the period of breeding, is of two 
kinds, the silent and the overt ; that is, it is sometimes 
attended, sometimes unattended by symptoms. The 
processes of eruption and maturation have Ukewise their 
respective fevers, called the eruptive and maturative 
fever. The term secondary fever expresses that renewal 
or exacerbation of febrile vsymptoms which happens 
when the specific fever ought, normally, to subside. It 
is commonly applied to small pox, but I shall have 
occasion to show you that each exanthema has its stage 
of secondary fever, characterized by a certain group of 
symptoms. Here we trace another important bond of 
connexion among the exanthemata. 

Nothing is more striking than to witness the uni- 
formity in the character of exanthematous fever, under 



rra dhiformitt and stkadinebs. 13 

every possible variety of external circumstHiice. Neither 
age, seasop. climate, nor habit of body, affects materiaUy 
the phenomena of small pos and measles. The 
description of the exanthemata handed down to us from 
the Arabians, corresponds perfectly wiili the appear- 
ances which we now witness: tlie European and the 
negro, the infant and the aged man, the strong and the 
feeble, suffer alike. The chief modifications of exanihe- 
niatoHs fever are the result either of idiosyncrasy or of 
a habit of body artificially engendered. 

The peculiarly steady conrse of exanthematous fever 
enables us to predict the result, or, as wc commonly 
say, to prognosticate, in eruptive fevers, with a certainty 
which it is not permitted us to do in any otiier tribe of 
diseases. Even the nurses at the Small Pox Hospital 
are rarely deceived. 

The notion that "fever precedes the specific action 
of the exanthematous poisons" has prevailed iu ail ages, 
and still iiolds its ground. You will find this doctrine 
distinctl)- laid down in I'r. Williams's work on the 
morbid poisons. He calls fever the primary effect of 
the pobon; affection of the skin and mucous mem- 
branes he calls the secondary effect of the poison ; and 
the inllammation of internal organs its tertiary effect. 

Having mentioned the work of Dr. Williams,* senior 
physician of this hospital, I should be doing injustice to 
my own feelings were I not to say that, in my judgment, 
it is the best specimen of elaborate research, of lucid 
and terse description, and of sound patholog)', which 
has appeared in this country — honorable aUke to the 
author, to this hospital, and to the age in which we

live. It is a work, which better than any other that I 
know, portrays the style of reasoning on matters of 
patholopjy prevailing in this country at this time, and as 
such will be quoted in after ages. It should be in the 
hands, not of the student, for he cannot appreciate its 
merit, but of every practitioner in this country, who will 
find in it rich stores of curious anecdote and useful 
instruction. 

High as the authority of Dr. Williams is, I shall 
occasionally venture to dissent from him, and shall do 
so on the present occasion. Dr. Williams, I have told 
you, upholds the ancient maxim that fever precedes the 
specific action of exanthematic poisons. The doctrine 
that I teach you, however, is, that exanthema may take 
place without fever, that the febrile state is not essential 
to the development of exanthem. For observe,— cow 
pox, varicella, inoculated small pox, and the mildest 
type of scarlatina, frequently display themselves without 
initiatory, without eruptive, nay, even without matura- 
tive fever. But further, I shall have occasion to show 
you, that the less the amount of fever the more perfectly 
is the eruption developed, and the more normal is the 
course of the disease. Any tunmltuous febrile action 
disturbs the regular progress of an exanthem. Witness 
scarlatina with excessive angina. There is here literally 
no eruption at all. We call the complaint angina 
maligna. Witness the recession of the eruption in 
malignant measles. Witness the ill-developed eruption 
of petechial small pox. This consideration is strictly 
practical. It shows the extreme folly of the old notion, 
that raising a fever by means of w^arm baths, heated 
rooms, and cordial alexipharmics, promoted eruption. 
It shows you the merits of Sydenham and of Sutton, 




BTMMETRT OF BXANTHBMATA. 

who, in consecutive centuries, did so mncli to improve 
the practice in small pox. It shows )oti that the 
violeuce of initiatory fever must often be subdued by 
active purgatives, by leeches, or even by venesection, 
to give the disease any chauce of running a safe course. 
As. then, there may be eruption without fever, the 
question may reasonably be asked — May there not be 
the specific fever of an exanthematous poison without 
eruption ! Has a man ever gone through small pox 
and measles without exhibiting eruption 1 In all ages 
this doctrine has obtained some supporters. Sydenham 
encouraged the notion that in epidemic years a variolous 
fever was to be met with whicli showed no eruption. 
Burserius, Vogel, Dellaen, Frank, Hedland, and others, 
have, in later times, avowed their belief in this Irish 
mode of undergoing small pox. Some couuteuance is 
given to the doctrine by the phenomena of cynanche 
maligna, but it is very questionable pathology, %\hich I 
cannot undertake to advocate. 

[Dr. Watson ngrves in opinion wilb onr author on the subject of the

2. T he second character of the exanthemata is 
derived from the presence of eruption. Here 1 must 
advert, for a few moments, to a doctrine recenUy brought 
forward under the title of the symmetry of diseased 
action; by which is understood the fact, that in disease 
both sides of the body are affected alike. This doctrine 
always reminds me of the Unes on Dutch gardening, 
where 

Grote nods At grove, ench al!-;y has its bruthur, 
And half the garden just reflects the other. 



16 SYMMETRY OF EXANTHEMATOU8 ERUPTION. 

In the case of this symmetrical disposition of disease, 
we are all, I suspect, pretty much in the same state as 
the Bourgeois Gentilhomme, who found out that he had 
been speaking prose all his life without knowing it. We 
knew the facts, but we had never reasoned concerning 
them. The chief illustrations of the symmetry of disease 
are to be found in the phenomena of rheumatism, in the 
mode of decay of the teeth, in the growth of certain 
tumors ; but, better than all, in the aspect of exanthe- 
matic eruption. In the corymbose form of small pox, 
the patches, or corymbi, will be found to correspond 
on the two sides of the body in the most singular man- 
ner. Once I had a patient at the Small Pox Hospital, 
who exhibited confluence in the highest possible degree 
on each hand and wrist, but in no other part of her 
body. 

[For striking illustrations of the symmetrical arrangement which 
patches of eruption assume, with many curious facts and much ingenious 
reasoning on the subject, see Paper on the subject by Mr. Jame^s Pfiget, 
and esj)eciaily a more extended one by Dr. William Budd, in Medico- 
Chirurg. Transactions^ vol. 25.] 

In all the exanthemata, the parts of the body nearest 
the centre of circulation are more affected than those at 
a distance. This is strikingly exempHfied in the erup- 
tion of post-vaccine small pox, which is often confluent 
on the face, and wholly undeveloped on the extremities. 

In general, the distinctive characters of exanthema- 
tous eruption are strongly marked, but difficulties in 
diagnosis do occur. Small pox is sometimes mistaken 
for chicken pox. Measles is not always readily distin- 
guished from lichen. 

When the exantliemata first invaded the world, their 
identity was universally beUeved. Rhazes and Avi- 




EXAKTHBMATIC IDENTITY. 

cenna taught that small pox and measles were the same 
disease. Kven so late as 1640 this doctrine prevailed 
all over Europe. Measles atid scarlatina continued to 
be confounded until about one hundred years ago ; nor 
has the bias in favor of exantheinatic identity, which 
our ancestors displayed, altogether subsided. Dr. 
Thomson, of Edinburgh, labored to prove that chicken 
pox is identical with small pox. Dr. Baron, Mr. Ceely, 
and others, who would be justly offended by the impu- 
tation of confounding scarlatina with measles, or measles 
with small pox, contend nevertheless strenuously for the 
identity of small pox and cow pox. 

That the disorders termed exanthemata bear a cer- 
tain pathological relatioo to each other cannot be 
denied, but this principle is probably not more applica- 
ble to siuall pox aud cow pox thau it is to small pox 
aud measles, to small pox aud chicken pox, to measles 
and scarlet fever. The epoch of the dilTusion of small 
pox and measles gives a certain countenance to such a 
doctriuc. The relationsliip may possibly consist in 
some modification of the elements which compose the 
morbid miasm, and may be analogous to that which 
subsists between the nitrous oxyde, the nitrous acid, and 
the nitric acid. Such a relationship, however, if admit- 
ted, is very different from the absolute idpullly for 
which Dr. Thomson and Dr. Baron contend. 

Nothing certaiu is known regarding the primary 
sources of the exanthematic poisons. The analogy of 
cow pox would lead us to conjecture that all (I mean 
the variolous, rnbeotous, and scarlatina!) were originally 
derived from cattle. Such an idea was entertained long 
before the discovery of vaccination. Dr. Layard, in 
1780, distinctly avowed his belief that the lues bovilla 



18 LAW OF SUSPENSION. 

was of the same nature as small pox. Navier (a French 
author), in 1753, traced the relation subsisting between 
scaflatina and the distemper of homed cattle, and came 
to the conclusion that scarlet fever was origmally com- 
municated from cattle to man. 

In some cases the body receives at one and the same 
moment the germs or miasms of two exanthemata, and 
though they occasionally proceed pari passu, the more 
usual law is that of suspension. Generally the lesser 
exanthem is suspended by the greater. Measles is sus- 
pended by small pox. Cow pox is held in abeyance by 
measles ; but instances of the reverse proceeding are on 
record. 

[For cases illustrating the co-existence of two febrile exanthcroala 
in the same individual, and the 8US{>ension of one by another, Bee

The connexion of exanthernatous eruption with a 
Uke affection of those mucous expansions or tissues 
which are in contact with the atmospheric air, and 
exposed to its direct influences, claims your especial 
attention. It is a feature in the eruptive fevers of the 
highest importance both in theory and practice. A 
V reason may be found for this connexion in the similarity 
of the structure and offices of skin and nmcous mem- 
brane. The epithelium of the one corresponds with 
the epidermis of the other. The result is, that all such 
mucous membranes are susceptible of the changes of 
efllorescence, papula, vesicle, and pustule. Small pox, 
measles, and scarlatina, alike exhibit, in their early 
stages, affection of mucous surfaces, — either of the nose, 
month, fauces, larynx, or trachea. Erysipelas some- 
times betrays the same tendency, and this strong dispo- 
sition of the morbid poisons to affect the throat is still

further exemplified in the pheuomena of hydrophobia 
and lues venerea. 

In some cases, the akin receives the whole violence 
of the poison ; sometimes the mucous membrane to the 
exclusion of the skin ; and in a third set of cases, both 
structures suffer. The blood, too, may be primarily 
afl'ected by the poison, even before the developmeat of 
fever (illustrating the principle, that the eruptive nisus 
is independeut of fever). But other organs occasion- 
ally suffer, when the miasm is very virulent, or the 
body in an unhealthy slate. Here we trace an import- 
ant bond of connexion between the eruptive and other 
kinds of fever. 

[In vAriola, rubeola, and Karlatina, Andral and Gavarret found the 
composition of (he blood very similar to what it is in continued fever. 
Some analyses gave negative results, while in others the tendency of the 
blood wa9 mora towards hyperinosis than hypinoais. 

The maximura of fibrin amounts to only 4.4, against which there ia 
a miiiimum of 1.1. In ihe majority of cnsea, it does not difibr much 
from Lveanu's normal average 3. 

The blood eorpnscles are increased in a l^s degree in variola and vario- 
loid, tbmi in scarlatina and rnbeoU. (Simon's Vhetnislri/, vol. i. 298.) 

Andral says that he has never met wiUi the bufl| unleaa there was 
some phli?gmasinl complication, either in inflammatory fever, in slight or 
severe typhoid fever, in measles, in scarlatina, or in variola. (PaOiolog. 
Hamaloloyij — translated by Drs. Meigs and StiUfe, p. 50.)] 

In typhus fever, rheumatic fever, and remittent fever, 
we observe the implication of internal structures. 
These most serious aggravations of eruptive malady, 
whether denominated secondary or tertiary, may occar 
at all periods of the exantheni. They may accompany 
the first burst of eruption ; — they may develope them- 
selves gradually during the niaturative stage, or period 
of concoction, hut they prevail chiefly towards the

20 SECONDARY AFFECTIONS. 

decline of the disorder, and in the course of secondary 
fever. 

I know of no exanthem which does not show 
secondary complications, no organ or structure which 
may not thus be dragged, as it were, into participation 
with the primary malady. 

In small pox we see the eye, the salivary glands, the 
brain, the pleura so affected. In measles we see the 
lungs, the larynx, and the mucous membrane of the 
bowels, secondarily affected. In scarlet fever the variety 
is still greater. The eye, the ear, the heart, the liver, 
the kidney, and the peritoneal surface of the bowels, 
are each, in their turn, the seat of superadded disorder. 
In certain cases, the morbid poison acts as directly on 
these internal structures as it does upon the skin ; but 
this is not a normal course of exanthematous disorder. 
The brain is especially liable to suffer in small pox, 
the lungs in measles, and the kidney in scarlet fever. 
When we consider the peculiar offices of the kidney 
and skin, we shall be at no loss to account for the 
implication of the kidney in a disease which suspends 
the function of the skin so completely as does scarlatina. 
Some of these internal complications, or superadditions 
to exanthematous malady, are explicable on other prin- 
ciples, especially those which occur after the climax or 
crisis ; when the virulence of the poison has, for the 
most part, expended itself. Thus, some are attributable 
to season, some to plethora, some to local weakness, 
the legacy of a prior ailment ; some to the coincidence 
of a typhoid or hospital miasm. The theory of a few 
cases must be sought for yet deeper, and may be found 
in that obscure law of the animal economy which, in 
other diseases, probably through the medium of the 
veins, tends to the formation of purulent depots. 



VARIETY IN THE COMPLICATIONS. 21 

k 

These secondary or superadded effects of the poison 
vary very much in violence. The pleuritic complica- 
tion in the secondary fever of small-pox, the pneumonia 
consecutive of measles, and the dropsy supervening in 
the latter stages of scarlatina, absorb every other con- 
sideration, and prove, in themselves, the direct causes 
of death. But other affections of the surface may take 
place besides the specific affection belonging to the 
miasm. Thus we may have small-pox followed by 
scarlatina — measles by erysipelas and gangrene — scar- 
latina by phlegmasia dolens. Some complications, 
again, are purely accidental, and this happens much 
more frequently in adult than in infantile life. In 
infancy the exanthemata occur for the most part uncom- 
plicated ; but as life advances, the probability increases 
of some accidental complication. Thus, for instance, 
small pox in the adult may be complicated with apo- 
plexy ; measles with phthisis; scarlatina with pregnancy. 
In infancy we sometimes meet with hooping cough 
complicating and thereby aggravating each of the erup- 
tive fevers. Painful dentition, in like manner, may be 
superadded to exanthematic disease, and contribute its 
share to the sufferings of the patient, and the result of 
the malady.

The eraptive fevers derive their third character from 
the law of universal susceptibility. 

No principle is more generally recognised than that 
small pox and measles necessarily and unavoidably 
occur to every man once in the course of life. The 
notion can be traced back even to the Arabians. Avi- 
cenna distinctly announces the fact, and strives to 
account for it Willis says, that the escape of a man 
living to the ordinary period of human Hfe from small 
pox and measles, is as rare as the falling into them 
twice. Both the one and the other he describes as 
vara et intcsitata eventa, Diemerbroeck is the only 
author I know who distrusted the doctrine of universal 
susceptibility, and he was doubtless influenced by the 
fact that he himself reached the age of seventy without 
ever experiencing an attack of small pox, though so 
continually exposed to the contagion. In the palmy 
days of inoculation, it was found that very few chil- 
dren were permanently unsusceptible, though, of course.

from temporary causes, the operation occasiouall}' failed 
of saccess. Dr. WoodviQe, my predecessor at the 
Small Pox Hospital, estimated the proportion of unsus- 
ceptible children at one out of sixty. The proportion 
of unsusceptible adults was consiilerablj higher, perhaps 
one in twenty. 

There are still some countries in the world not yet 
visited by the exanthemata. Small pox, measles, and 
scarlet fever, are to tliis day unknown in Australia and 
Van Diemen's Land. 

All the exanthemata have sprung up since tlie com- 
mencement of the sixth century. The dates of the first 
appearance of each exanthem will be duly investigated, 
as constituting an interesting branch of medical chro- 
nology. That a "nova febrium cohors" should thus 
invade the earth need not surprise us when we reflect 
that, within our own times, two have started into exist- 
ence — Vaccinia and Asiatic Cholera, — the mildest and 
the most malignant of human maladies, the Alpha and 
the Omega in the catalogue of nmrbid poisons. How 
many more of what Gray describes as 

"The painful fumily of deatb. 
More Lideous Uiaa tlieir queen," 

lie concealed in the womb of time it is not for us to 
say, hut we may reasonably conjecture from what we 
know of the origin and succession of epidemic mala- 
dies, that nature has not yet exhausted her store of 
wide-wasting pestilences, and that others remain to 
afford occupation for the pathologists and physicians of 
succeeding ages. 

The fourth peculiarity of the exanthemata is derived 
from the law of non-recurrence. It was formerly held 



24 LAW OF NON-RECURRENCE. 

that scarce any one had small pox or measles a second 
time. This doctrine was sedulously inculcated during 
the greater part of the last century, when the philan- 
thropic mind was laboring to encourage the practice of 
inoculation. 

Dr. Mead of London, the elder Monro of Edinburgh 
(two of the best practical physicians of the last century), 
doubted the possibility of small pox recurring. De 
Haen, De la Condamine, and Dr. Heberden, spoke of 
it as a possible but most unusual event. Times are 
changed. Vaccination has taken the place of inocula- 
tion, and now, to screen the obvious defects in the pro- 
tective power of the cow pox, pathologists have wheeled 
round, and many, in their zeal, would fain persuade us 
that the recurrence both of small pox and of measles is 
far more frequent than our forefathers were willing to 
admit The friends of vaccination, says Dr. Baron,* 
were compelled to prove that the small pox occurred a 
second time, and in so doing were accused of drawing 
upon their imagination. To determine the truth in a 
matter of such interest may profitably employ a few 
minutes of our time. 

Imnmnity from second attacks of the same disease is 
a very extended and a very important principle in 
pathology. It does not merely apply (as the world 
would have us to believe) to small pox, measles, and 
hooping cough, but to all diseases whatever which origin- 
ate from a poison or miasm — which are, as we say, of 
miasmatic origin. It belongs, therefore, to scarlet fever, 
yellow fever, typhus fever, and Egyptian plague. It 
belongs, in a certain limited degree, to fevers of paludal, 
terrestrial, or, as we sometimes say, of endemic origin — 

* Baron's Life of Jenner, vol. i. p. 226. 




ORIGIN FKOM CONTAGION. 

that is, to ague and remitting fever ; for ibese fevers are 
curable while the patient is still resident in the 
unhealthy locality, and a certain time elapses before the 
constitution is susceptible of a second seizure. So also 
with gout and rheuniatisni, fevers of internal origin. It 
is well known that these diseases recur again and 
again, and at length rivet themseivcs on tlie system. 
Nevertheless, we congratulate a friend, with perfect 
justice, when we hear tliat he has had a fit of the gout, 
because we feel sure that for a certain time he will be 
free from similar attacks. In all cases, therefore, the 
susceptibility of a disease is more or less exhausted fay 
once undergoing it, A gradation in this respect may 
easily be traced from rheumatism and gout (where the 
law obtains least) through ague and every variety of 
endemic fever, whether remittent or continued, up to 
plague, scarlet fever, typhus, yellow fever, measles, and 
small pox. The law of non-recurrence is more strik- 
ingly displayed in measles and small pox than in any 
other known disorder. Nevertheless, exceptions occur 
even here, of which due mention will be made in future 
parts of the course. 

We now approach the fifth characteristic of the 
exanthemata — contagious origin. 

The diseases of tlie human body arc divisible into 
two great classes — those of constitutional and tiiose of 
accidental origin. This distinction is very obvious in 
surgery. Cancer, fungus haematodes, stone in the 
bladder, white swellings, psoas abscess, aneurisms, — all 
arise from internal causes, and are of constitutional 
origin Again, fractures, dislocations, sprains, wounds, 
bums, scalds, and contusions, are the result of external 
and accidental causes. In a community where there 



26 ACCESS OF CONTAGION TO BODY. 

were no railroads, no runaway horses, no high scaffold- 
ings, no deep mines, no cotton mills, and no careless 
servants, a sui^eon might practise for many years 
without ever meeting with any disorders but those of 
constitutional origin. 

Now the same distinction holds good in physic. 
There are medical as well as surgical accidents. Drop- 
sies, inflammations, haemorrhages, apoplexy, palsy, and 
jaundice, are all constitutional maladies, arising from 
such internal causes as the following : — Advancing age, 
scrofula, original weakness of constitution, the gouty or 
rheumatic diathesis imprinted on the individual at birth 
and descending to him from his parents. 

The second class of medical disorders are those of 
accidental origin — the results of overfeeding, of intem- 
perance, of exposure to cold, of excessive fatigue, but 
above all, of those deleterious agents received into the 
body from without, which we call miasms or poisons. 
The most interesting disorders belonging to this class 
are the exanthemata ; but, besides them, we enumerate, 
as associated with them, the venereal disease, gonor- 
rhoea, hydrophobia, hooping cough, plague, and some 
others of lesser moment These all originate from the 
miasms of an animal body laboring under disease, and 
we therefore call them the true morbid poisons. Ague, 
remittent fever, dysentery, and cholera, arise from ter- 
restrial miasm. In Dr. Williams's work, however, you 
will find all these diseases treated of under the general 
appellation of the " morbid poisons !' 

The contagion, infective miasm, or materies morbid 
obtains access to the human body in three modes. First, 
by the inhalation of air tainted by the breath or perspi- 
ration of a patient. This is called the mode of infec- 



INOCULATIO^. 

tioD. Small pox, measles, plague, typhus, scarlatina, 
and erysipelas, are thus comumnicatcA Experiments 
have been made to determine the limit of infective 
distance, but nothing very satisfactory is known con- 
cerning it. It probably varies from a few feel to many 
yards. 

2, Miasms gain access to the body, secondly, by solu- 
tion in the fluids, or humors, and subsequent appUcalion 
to the unbroken surface. It is thus that psora, tinea 
capitis, gonorrhoea, and the venereal disease, arc com- 
municated from man to man. We call this mode 
contagion, "a cff«/«c/« corporis." Remember that the 
matericsmorhi must be dissolved. " Corpora non agunt 
nisi solula," was a dogma of the old chemists. It is 
equally true of the animal body. Fluidity is essential 
to all the great processes going on witliin the animal 
economy, a principle which those who vaccinate from 
points and glasses are very apt to forget. The germ of 
disease is conveyed in the fluid form in the interior of 
the frame, where it mixes with and taints the blood, the 
most complex, the most perfect, and the most essential 
to life of all the animal fluids. 

Strongly impressed with the importance of these 
tilings, the ancient physicians professed themselves 
humoral pathologists, and the current of modern disco- 
very is running rapidly into the same channel. Witness 
the importance attached to the condition of the urine in 
disease, and observe with what interest all microscopical 
observations on the blood and its secretions are now 
received. 

3. Certain of the morbid poisons are not admitted 
into the frame unless (srill after solution in the animal 
fluids) they are applied to an abraded or wounded sur- 



28 INOCULATION. 

face. Hydrophobia, vaccinia, and farcinoma (or glan- 
ders), are received in tliis mode. Small pox and plague 
may thus be excited artificially, and the process is, as 
you know, called inoculation. 

One of those curious points in pathology which is 
now attracting the attention of Continental physicians, 
is the direct communication of disease by means of the 
blood, and not by the secretion derived from the blood. 
It is very reasonable to suppose that such may be the 
law of nature. All infection is probably direct from the 
blood. The injection of the blood of a glandered horse 
into the veins of a healthy horse communicates that 
disorder. Measles has been communicated by inocula- 
tion with the blood in so many instances, and by so 
many experimenters, and recently in the Austrian terri- 
tories on so large a scale, that no doubt can exist as to 
the possibility of thus exciting the disease. I have often 
noticed that if the vaccine vesicle be punctured so deeply 
as to bleed, the lymph is equally effective as when per- 
fectly colorless and pure. All these things point to an 
important principle — the direct communication of dis- 
ease by means of the blood. Whether the resulting 
disorder be thereby rendered milder, as in the ordinary 
process of inoculation from secreted humor, or not, is a 
question for our future consideration. 

Each specific miasm has its respective laws — its 
period of latency, of development, and of decline. With 
reference to the period of incubation, the morbid miasms 
are divisible into three classes : — 

1. Those of rapid incubation — viz., chicken pox, 
plague, scarlatina, and gonorrhoea. In these instances 
the latent period is less than a week. 

2. Those of mature incubation, the period extending 



THEORY OF ZYMOSIS. 

from ten to fourteen days. In this class come small 
pox, measles, and hoo^iiiig cougli. 

3. Those of ;firfio«.s incubation (extending from fonr 
to six weeks). In this class we place hydrophobia, 
secondary syphilis, and endeniial remittent 

From the earliest period at which the existence of 
morhid poisons became known, the analogy of vegetable 
formentatiou has been adduced to explain their 7/wdtts 
oj}erandi. Tiie doctrine of a fermentative process going 
on during the incubation of small pox and measles, was 
distinctly announced hy Sydenham, Willis. Dienier- 
broeck, and Morton, Liebig has lately ^ven increased 
interest to this portion of pathology, hy reviving the 
hypothesis of fermentation, and investing it with a sci- 
entific character. " The phenomena attending the 
transformation of organic vegetable compounds afford," 
he says. " not merely an analogy, bnt a correct explana- 
tion of the changes taking place in tlie animal economy 
by the agency of morbid poisons." Nothing, however, 
can be clearer than that in this notion, whether correct 
or not, Liebig is anticipated by Diemerbroeck, who 
flourished two htmdred years ago. " Out of an infected 
body," says he, " flow forth continual streams, which, 
being received by other bodies, presently feniient with 
the blood, and excite the latent and homogeneous seeds 
of the same distemper, disposing them into tlie idea or 
character of the same disease." 

Mr. Farr, in his fourth report, recently submitted to 
parliament, proposes to call all those diseases which 
have the properly of comnmuicating their own action, 
and eflbcting analogous transformations, zymotic dis- 
eases (from ^uf"^. to ferment), and the action itself) 
zymosis. Zymotic diseases will comprehend all those 



30 QUARANTINE. 

now associated by the tedious periphrasis of " epidemic, 
endemic, and contagious maladies." The terms appear 
to me to be judiciously chosen, and I shall employ 
them in these lectures. Zymosis, you will remember, 
is applied to a process of the aniinal economy ; fer- 
mentation to the mutual action of vegetable principles. 

One very remarkable character of the zymotic 
miasms is, that they operate upon the healthy body 
without the aid of predisposing causes. A man in the 
most perfect health contracts small pox or measles, and 
this state of body is the best possible for insuring the 
success of inoculation and vaccination. Almost all 
cases of vaccination which progress unfavorably, may 
be traced to some previously unhealthy condition of 
the humors or secretions. A characteristic feature, 
then, of the exanthemata is ''absence of predisposing 
causes^ 

All miasms of animal origin are capable of attaching 
themselves to fomites, and (provided they be excluded 
from the air) of retaining their communicating property 
for a considerable length of time. This great law of 
nature is the foundation of that important practical 
measure — quarantine. It is a law of universal applica- 
tion. Tinea capitis spreads by means of hats, combs, 
and brushes ; Egyptian ophthalmia by towels and 
sponges ; small pox and typhus by clothes and bedding ; 
plague by personal apparel and old rags. Some would 
persuade us that merchandise, which, ex necessitate ret, 
could never have been near the chambers of the sick, or 
handled by others than by men in health, may also com- 
municate contagion ; but I believe this doctrine to be 
opposed to every principle in sound pathology. 

Reasoning chiefly from the well established fact that 



QUARANTIHE. 31 

medical men very seldom communicate the seeds of 
disease, Dr. Ha^'garlh discredited the doctrlno of com- 
munication by fomites. That fact, though it will not 
hear out Haygarth in his speculations, sufficiently proves 
how exceedingly volatile contagious miasms are, and 
how short an exposure to the air deprives ihem of 
noxious quality. The term of forty days, originally 
judged necessary for the security of the community, is 
founded on utter ignorance of the laws of morbid poi- 
sons. As the incubative stage of plague never exceeds 
seven days, so one week of quarantine is, in strictness, 
sufficient, and two weeks should satisfy the uioi-t scru- 
pulous auxiety. 

[The CommissioD of the French Academy of Modicinc, apiwintej in 
1844 to report on the subject of Plague and Quaranlitiea, say that at n 
distance from countries where it is endemic, and IwyorKl or iiuay from 
epidemic fwi, the pliigue has ne»er broken out in i>ersoiiFi who Lave 
been exposed to its influence after an isolation of eight Jiiys.] 

The period of quarantine, too, may safely commence 
from the departure of tlie ship from the suspected port. 
This great improveuient in commercial intercourse is 
now sanctioned by the British Government. 

You will lake notice, that all fomites or harborers ol 
contagion are substances of a rough surface or downy 
texture. Wool, cotton, leather, every kind of apparel, 
the dust accumulated on walls, floors, and ceilings, are 
those against which it behoves you to be most on your 
guard. By universal consent it is admitted that money 
and ail metallic substances are incapable of harboring 
contagion. 

6. The sixth and last character of the exanthemau 
is drawn from their occurrence as epidemics. This 
term is derived from the Greek words .=«■ and Jr,pc, and 



32 THEORY OF EPIDEMIC INFLUENCE. 

simply expresses the fact of the spreading of a disease 
among the people without reference to the precise fnode 
of communication. Some diseases therefore are conta- 
gious but not epidemic, as ophthahnia, gonorrlioea, and 
porrigo. Some are epidemic but not contagious, as 
catarrh, diarrhoea, and pneumonia. 

Lastly, some diseases are botli epidemic and con- 
tagious, as small pox, measles, scarlet fever, typhus 
fever, plague, and probably also cholera. These are the 
diseases which, rising occasionally like a mist out of 
the earth, shed desolation on nations, to disappear as 
rapidly and insensibly as they arose. The origin of all 
such disorders is necessarily obscure, but the obscurity 
has proved no stumbling-block in the path of medical 
theorists. In ancient times their appearance was attri- 
buted to the direct agency or influence of the sun, moon, 
and stars (whence the term injluenza, applied to the 
least energetic among them). Sydenham connected 
them with some supposed movements going on below 
the earth's surface, in ipsis terne visceribus. Some 
modern pathologists attribute them to the condition of 
the surface itself; some find, or pretend to find, their 
source in mysterious changes of the atmosphere ; others 
in heat, imperfect ventilation, or some bad quality of 
food. Dr. Holland looks with favor on the animalcular 
origin of epidemic maladies, while Diemerbroeck can- 
didly avows his belief that this is one of those mysteries 
which nature for ever intends to keep to herself. 

The present most approved theory of epidemic 
influence attributes everything to the atmosphere, but 
neither the thermometer, nor the barometer, nor the 
hygrometer, nor the electrometer, aids us in our re- 
searches. The best prospect of attaining to truth in 



EPIDBHIO INFLUENCE. 

this recondite branch of pathology is afforded by the 
increasing fondness for statistical researches. Their 
improvement and extension to eastern countries, where 
all wide-spreading epidemics seem to originate, may 
perhaps discover order where all is now confusion and 
vague conjecture. 

Seven maladies are acknowledged on all hands as 
genuine epidemics. These are Small Pox, MEAaLEs, 
Scarlet Fever, Hooping Cough, Typhus, Cholera, 
and Influenza. The Registrar-General of England 
admits, in his Statistical Reports, four other disorders 
into the category of epidemics, namely : — croup, thrush, 
diarrhoea, and dysentery. Their claims to this distinc- 
tion are not, however, so generally conceded. At any 
rate, on the same grounds, pneumonia might lay claim 
to the title of an epidemic. 

Although we make no pretensions to a knowledge 
of the ultimate cause of epidemic visitation, yet there 
are certain laws, having reference to the diffusioa of 
epidemics, which are sufficiently established. 

It is seldom lliat two diseases are epidemic at the 
same time in the same district When the yellow 
fever raged with such violence at Gibraltar in 1804, it 
was remarked that all other diseases declined ; and well 
they might, for in that fatal epidemic, out of a civil 
populatiou of 14,000 persons, 28 only escaped an attack. 
We may hence learu why, during the presence of an 
epidemic which proves fatal at a high per centage, the 
sum total of annual mortaUty is often not sensibly 
augmented. The reason is obvious. Other diseases 
fall off, and if men die of cholera, or children of small 
pox, they are not left to be ihe prey of pneumonia or of 
hydrocephalus, of asthma or of croup. 



34 EPIDEMIC VISITATION. 

There are some exceptions to the law that only one 
epidemic can rage at one and the same time. In 1839, 
both small pox and measles were epidemic in England 
and Wales. 

. [Small pox and scaiiet feTer were both epidemic in New York in 
1840, '41, '42, and '43 ; and in 1840 and '41 measles was also epi» 
demic, so that the three diseases were epidemic together daring the two 
last mentioned years. 

Measles and small pox were also both epidemic in Philadelphia in 
1828 and 1824; and in 1885, small pox, measles, and scarlet fever, 
were all epidemic, as was also the case in 1845. 

Measles and scarlet fever were both epidemic in Baltimore in 1887, 
and small pox and scarlet fever in 1838, and again in 1845, in that ci^.] 

^ On the succession of epidemic maladies we have as 
yet no details that can be relied on, but this branch of 
the subject invites inquiry, and promises results both 
curious and useful. We may safely leave it in the 
hands of Mr. Farr, whose laborious investigations have 
already done so much to elucidate the truth, conducted 
as they have been with great judgment, and guided by 
sound views of pathology. The notion once enter- 
tained of the recurrence of epidemics in cycles of five, 
seven, or ten years, has been disproved by modem sta- 
tistics, the cultivation of which will probably serve to 
dispel many other long-established opinions, or rather 
prejudices, in physic. 

[Epidemic diseases seem to be more fatal among the uncivilized than 
the civilized. In an epidemic of Rubeola among the Crees (a tribe of 
North American Indians) in the summer of 1846, as reported by Dr. 
Smellie {Monthly Journal of Medical Science^ December, 1846), in 145 
cases treated in their camp, 40 were fatal. 

Small poz bas sometimes swept off an entire tribe of Indians, as was 
die case with the Mandans (another North American tribe), and has 
been raging with great fatality among some other tribes of these Indiana 
daring the past and present year.

In Chwleston (8. C), the mortality by small pox during the period 
from 1S22 to 1848 ioclusive, was 49 among the white population and 
154 among Uie blacks. Within the same period, 289 whites and 163 
blaoka died with scarlet fever, and 45 whites and 97 blacks died with 
nieaslee; and 100 whites and 257 blacks with hooping cough, — the 
population of the whites being 12,828, and of the blacks 17,461, in 
1830; and 13,000 whiles, to 16,200 blacks, in 1840. (Cmsut of 
Charlalmt, by Drs. Dawson and De Saussure. 184D.)] 

It iias always been observed that epidemics are unu- 
sually severe when they first appear in any counlry, or 
are renewed after any long interval of time. When 
cholera first invaded Jndia, in 1817, it raged with an 
intensity which may have been equalled, but never has 
been surpassed. When the cynauche maligna first in- 
vaded Naples, in 1618, — when small pox first appeared 
in America (1518), — when the putrid sore throat first 
invaded America in 1735, and London in 1747, — the 
ravages of each disorder were terrific. It seems, then, to 
be a law of the animal economy, that the susceptibility 
to any morbid poison is great in proportion as it has 
been Uttle accustomed to the impression.

developed ; but you are not to set this down as an uni- 
versal law. The truth is, not many of the exanthemata 
last long enough to induce real debility. What men 
call debility is, in nine cases out of ten, secondary fever. 
If the theory of debility be adopted, and beef tea, wine» 
bark, and tonic medicines, be administered, you feed 
the fever, and make bad worse. Not long ago, I saw 
peritoneal inflammation occasioned by acting on this 
false notion of exanthematic debility. Secondary fevers 
must be reduced, like other fevers, by purgatives, diure- 
tics, and low diet. You cannot safely stimulate in 
secondary fever. 

To no disease does this principle apply more strongly 
than to scarlet fever. I have seen this exanthem fol- 
lowed by true debility ; but febrile or apparent debility 
is far more common. The circumstances which indi- 
cate real debility in the several exanthemata will be 
mentioned hereafter. 

Much of what applies to the treatment of common 
fever applies also to the exanthemata. These points 
will be more fully detailed to you hereafter ; but I may 
select two general principles as illustrative of my mean- 
ing:— 

1. One of the chief features of fever, both in a theo- 
retical and practical aspect, is the general diminution 
of secretion observable all over the body. The secre- 
tions of the mouth, the stomach, the mucous membrane 
of the intestines, the kidney, the Uver, and the skin, are 
alike checked during the presence of fever. Whatever 
therefore encourages secretion aids and assists in the 
expulsion of fever. We employ, therefore, diuretics and 
diaphoretics,— calomel, with James's powder, or the 
antimonial powder, saUne draughts, saUne purgatives* 



INFLUBNOE OP HIDICIHB. 

jaiap with cream of tartar, senna with the sulphate of 
magnesia. 

2. On tlie very same principle, we avoid opiates as 
far as possible, for all opiates confine the secretions. 
Opium given to a man in health, per se, occasions a 
state of ephemeral feverishness, like wine. Opium 
locks up the bowels, diminishes the urine, causes (hirst 
and a dry tongue. But it does more when the system 
is already laboring under fever of any intensity. It then 
disturbs the circulation very materially. It occasions, 
or at least aggravates, congestion in the larger vessels, 
whether in the head, chest, or belly. We often see 
opium in fever producing piles. In all exanlhematous 
fevers, therefore, let opium be avoided, or administered 
with such correctives as this evU tendency of the medi- 
cine nafurally suggests. 

When all is done, you will not fail to remark how 
small a proportion the strictly therapeutical and practical 
parts of the course bear to the descriptive and patholo- 
gical portions ; it will often remind you of Falstaff's 
ka'porth of bread to his two gallouH of sack. Remem- 
ber, however, that in the e.\act proportion in which wc 
improve the two latter, we diminish not the importance, 
but the extent, of the former. In the early periods of 
medicine, when descriptions of disease were imperfect, 
and pathology was in its infancy, and statistics were 
unknown, physicians arrogated to themselves a power 
of controlling, by drugs, the course of diseases (and 
especially of exanthcmatic diseases), which we now 
know to be wholly unwarranted. Pages and chapters 
were devoted to objects quite unatlaiuable ; presenting, 
indeed, an imposing, but a vain parade of learning. In 
tliis respect we have improved upon our predecessors. 



40 INFLUENCE OP MEDICINE. 

We are not ashamed to acknowledge that many diseases 
must ran their stated course, and that others will ran 
their coarse, in defiance of all the efforts of medical skilL 
In the management of the exanthemata, be satisfied 
with steering the ship. Do not attempt to quell the 
storm. Trophilus, an ancient Greek physician, being 
asked who was the most perfect physician, replied, " He 
who knows best how to distinguish that which can 
from that which cannot be done."

Small Pox is the most remarkable of all tbe eraptive 
fevers, and though I once proposed to begin with the 
simple efflorescences, and proceed thence to small pox, 
the most highly developed form of exanthematic disease, 
yet I find that otlier and more imporlaat objects will be 
gained by beginning with small po.v. A brief sketch of 
the early history of this disease will be quite essential 
to a due understanding of the subject 

The Greeks and Romans knew nothing of small 
po.'c. It is very true that Hahn in former times, and 
Dr. Willan and Dr. Baron in our own, have labored 
diligently to prove the contrary. Mr. Moore, too, has 
been no less anxious to convince us that small pox was 
known in China aud Hindostan even before the time 
of Hippocrates ; but 1 am very incredulous on these 
points, and am borne out in this scepticism by the 
opinions of Dr. Friend, Dr. Mead, and many other 
physicians of great learning, and equally indefatigable 
in research. 



42 PESTILENCE OF PR0COPIU8. 

In the writings of Alexander Trallianus, who lived 
in the first half of the sixth century, we have a brief 
description of the whole circle of medical science as it 
existed in his days. No allusion to any complaint 
exhibiting the character of small pox is there to be met 
with. 

The first notice of a disease that looks like small pox 
is to be found in a chapter of Procopius, " De Belle 
Persico" (lib. it cap. 22), where he describes a dreadful 
pestilence which began at Pelusium, in Egypt, aboat 
the year 544, and spread in two directions, towards 
Alexandria on the one side, and Palestine on the other. 
This disease, he says, was accompanied by buboes and 
carbuncles. So far it resembled Egyptian plague ; but, 
on the other hand, Procopius distinctly states that it 
raged independent of all season ; that it spread into 
Persia and thr ugh the whole interior of Asia, and did 
not confine itself to the shores of the Mediterranean 
and Red Seas ; that it spared neither age nor sex ; that 
it affected the whole human race alike ; that it was a 
new disorder, so little understood by the physicians of 
those days, that many recovered whom they had given 
over as hopeless, and many died whom they had pro- 
nounced safe. It is stated, also, that it was peculiarly 
severe in pregnant women. All this looks very Uke 
small pox. 

Whether this epidemic was or was not small pox 
may be doubted ; but certainly, within a short time 
afterwards, very unequivocal traces of small pox are to 
be met with in the countries bordering on the Red Sea, 
for we read of caliphs and caliphs' daughters being 
pitted. Mr. Bruce, the celebrated Abyssinian traveller, 
wishes to fix the first epidemic of small pox to the 



era 522, which corresponds sufficiently near to the date 
of this plague described by Procopius. 

Small pox had cerlainly been known for several cen- 
turies before it was described. Rhazes (910) is the 
first author who mentions it: his description is clear 
and full, his tlieory childish in the extreme, and his 
practice very bad. Avicenna and Hali Abbas, the 
Arabian physicians who succeeded Rhazes, also men- 
tion variola, adding some facts to those already 
described. 

From the east small pox travelled to the west, 
whether slowly or quickly we have no means of ascer- 
taining. It appears to have reached England towards 
the close of the ninth rentury. The word variola is to 
be found in several Latin manuscripts preserved in the 
British Museum, of date decidedly prior to 900. Exor- 
cisms to ward oif the dangers of this new plague are to 
be found addressed to St, Nicase. The term variola, 
the diminutive of varus, a pimple, is obviously of monk- 
ish origin. The monks, you know, were llie deposito- 
ries of all the little medical learning of those times. 
The term pock is of Saxon orlgiu, and signifies a bag 
or pouch. The epithets amc// in England, and petife in 
France, were added soon after the introduction of the 
grand or great pox in 1498. 

If America (discovered in 1492) gave us, as people 
confidently say it did, the great pox, we more than 
returned the compliment by introducing to her acquaint- 
ance the small pox. This pestilence reached the 
American Continent about 1527, devastating in the 
first instance Mexico, and spreading afterwards with 
fearful virulence over the whole of that vast country, 
[■■ Acconling to Humboldt, variola was introduced into Mexico in 



44 FIRST APPEARANCE OF SMALL TOX. 

1520, bj a negro slave ; and, from this period, it exercised its ravaget 
throughout that extensive region at regular intervals of 17 or 18 years; 
and notwithstanding European vessels frequently introduced the vims 
anew subsequently, it never became epidemic except at those very 
marked intervals of time.** (Forry. i^. Y. Joum, Med^ March, 1844, 
p. 156.) 

Webster (Hint. Epidemic Diseases, vol. i. p. 292) says that "in 1638 
the Indians in Massachusetts were invaded by the small pox, which 
swept them away in multitudes." 

He speaks of it as having first occurred in Boston in 1649, and sub- 
sequently in 1666, 1678, 1689, 1702, 1721, 1730, 1752, and 1764.] 

The ravages of small pox, great as they are in tempe- 
rate climates, are far greater in tropical ; severe as they 
are in the white skin, they are far severer in the black 
and colored races. 

[In the year 1752, when this disease prevailed as an epidemic in 
Boston, the mortality was about fifty per cent greater among the 
blacks than among the whites, when taken in the natural way ; and 
more than three times as great, when taken by inoculation. (Vital 
Statistics of Boston, by L. Shattuck. Amer, Jour, Med, Sci,, Jan. 1841, 
p. 372.) 

The statistics of Charleston (S. C), already quoted, show the same 
fact of the greater fatality of the disease among the blacks than the 
whites.] 

Skipping over 120 years, the era at which I shall 
next pause is 1640, when the mode of treating fevers 
by the hot or sweating system had attained its acme. 
We have a splendid picture of this practice in the 
writings of Diemerbroeck, a Dutch physician and pro- 
fessor. I must treat you to some few traits of this 
.system, premising that it was especially applicable to 
small pox. 

" Keep the patient," says Diemerbroeck, ** in a cham- 
ber close shut. If it be winter, let the air be corrected 
by large fires. Take care that no cold gets to the 



THE SWEATING 8TSTK1I. 

patient's bed. Cover him over with blatikets. Red 
blankets have always been preferred — not that the color 
is material — bat because, in the limes of our ancestors, 
alt the best, tliickest, and warmest blankets, were d}*ed 
red. Never shift the patient's linen lill after the four- 
teenth day. for fear of striking in the pock, to (he irre- 
coverable ruin of the patitmt. Far better is it to let the 
patient bear with the stench, than to let him change his 
linen, and thus be the cause of his own death. Never- 
theless, if a change he absolutely necessary, be sure that 
he puis on the foul linen that he put oiT before he fell 
sick, and, above all things, take care tliat tliis supply of 
semi-clean linen be well warmed. Sudorific exputsives 
are, in the meantime, to be given plentifully, such as 
treacle, pearls, and saffron." 

This is an abbreviated sketch of the system of expel- 
ling the peccant humors in fever by perspiration ; and 
such was the condition in which Sydenham found the 
practice of medicine in 1667. He had an Augeao 
stable to cleanse when he undertook the task of reform. 
Unless you have .well studied the writings of physicians 
during the first half of the seventeenth century, you can 
form no just estimate of Sydenham's merits. He was 
violently attacked by his contemporaries for the system 
which he quietly substituted, but truth ultimately pre- 
vailed, and before the end of the century the new or 
cooling plan of practice was fully established. Syden- 
ham had other merits in regard to small pox. He 
desiTibed die disease admirably, and was the first who 
separated small pox from measles. 

JJoerhaave, who flourished about the year 1700, was 
a devoted admirer of Sydenham. He deserves mention 
as the author who first excluded all commou causes 



46 IKTftODCCnCMI AMD FEOGKBSS 

from the edoiogj of smaO pox, and maintained that it 
was propagated bj a specific contagion or miasm alone. 
This brings ns to the next great epoch — that of ino- 
eolation. It was at Constantinople, abont the year 1 700, 
when inoculation for the small pox was first practised. 
Dr. Emanuel Timoni, Mr. Kennedj, and Dr. Pjlarini, 
in 1714-15, made the profession in England acquainted 
with the discovery, but no attention was at first paid to 
it It was reserved for a ladj — Ladj Marj Wortley 
Montague— to introduce this splendid improvement into 
medical practice. Her son was inoculated at Constan- 
tinople in 1717, and her daughter was reserved to be 
the first person ever inoculated in England. This event 
took place in 1721. 

[Inoculation was first advocated in this oountrj by the Rev. Cotton 
Mather, and first practised, at his suggestion, by Dr. Z. Bovkton, on the 
27th of June, 1721, in Boston, upon bis only son, about thirteen yean 
of age, and two negro servants, and was entirely successful. During 
that year and the early [>art of 1722, he [performed it upon 247 persons 
himself. Tlie opposition which the introduction of the practice met^ 
and which was carried so far as to endanger his life, the courage and 
energy as well as perseverance with which he carried di rough to final 
triumph his bold and humane undertaking, and his eventual reward in 
the amount of good accomplished, in the acknowledgments of those who 
bad l>een his persecutors, and in pecuniary returns, are interesting mat- 
ters of historic record. (See Thacher^s American Medical Biography ; 
Boston, 1828, p. 28 ; also under head of his life in same work.)] 

In the following year, after successful trials upon six 
condemned criminals in Newgate, the Princess of 
Wales submitted her own daughters, the Princess 
Amelia and Caroline, to the new process. Both passed 
through the small pox favorably. The anxiety of the 
Princess of Wales on this occasion admits of easy ex- 
planation. 

dueen Mary, wife of William the Third, died of 



OP INOCULATION. 

confluent small pox of ihe worst sort, at the age of 32, 
on tUe 28tli December, 1G94. In 1721, George the 
First had but recently come to the throne, and the direct 
succession of the Hanoverian line was of the otmost 
consequence to the court and the nation. Q.ueen 
Mary's death had made a deep impression, which an 
interval of 25 years had not banished from the recollec- 
tions of the people, Hence doubtless arose the ex- 
treme anxiety of the Princess of Wales to fly to the 
novel expedient of inoculation. 

The first ten years of its career were singularly 
unfortunate. It fell into bad hands. It was tried on 
the worst possible subjects, and practised in the most 
injudicious manner. The consequence was, that it 
soon fell into disrepute. The pulpit, too, sounded the 
alarm, and in trulh, conducted as inoculation then was, 
it was a very questionable improvement. 

A new era arises in 1746, when, the practice being 
better understood and appreciated, the Small Pox Hos- 
pital was founded, to enable the poor to participate in a 
benefit hitherto confined to the rich. In 3 754, the 
College of Physicians put forth a strong recommenda- 
tion of inoculation. About the same period, Mead and 
De la Condamine wrote treatises in favor of it, the 
former in London, the latter in Paris. At length, in 
1763, the practice was undertaken by an exceedingly 
clever man, Mr. Robert Sutton, who, >vith his two sons, 
inoculated with admirable skill and wonderful success. 
In 1775, a dispensary was opened in London for the 
gratuitous inoculation of the poor at their own houses; 
but the iustilution failed, chiefly through the opposition 
of Baron Dimsdale. The Small Pox Hospital then 
took up the plan of promiscuous inoculation, which 



48 DEFINITION OF SMALL POX. 

was carried on to an immense extent between the 
years 1790 and 1800. 

In 1798, Dr. Jenner announced the discovery of 
vaccination. On the 5th of May, 1808, the inoculation 
of out-patients was discontinued at the Small Pox Hos- 
pital. On the 20th June, 1822, inoculation was discon- 
tinued to in-patients. On tlie 23d July, 1840, the 
practice of inoculation, the introduction of which has 
conferred immortality on the name of Lady Mary W. 
Montague, which had been sanctioned by the College 
of Physicians, which had saved the lives of many kings, 
queens, and princes, and of thousands of their subjects, 
during the greater part of the preceding century, was 
declared illegal by the English parliament, and all 
offenders were to be sent to prison, with a good chance 
of the treadmill. It is even provided that an attempt to 
produce small pox by inoculation, even though unsuc- 
cessful (including, of course, the testing of vaccinated 
subjects at all ages), is an offence at law ! Such are 
the reverses of fortune to which all sublunary things are 
doomed. 

We define small pox to be a disease, the product of 
a morbid poison or miasm, which, after a certain period 
of latency, developes eruption on the surface, passing 
through the stages of pimple, vesicle, pustule, and scab^ 
with certain other, concomitant or succeeding affections, 
which runs a stated course, and having exhausted itself, 
removes from the constitution the susceptibility of a like 
attack. 

Small pox. is divisible into varieties. The terms 
confluent and distinct express two of the most remark- 
able, but others are equally important. I shall speak 



PERIOD bF INCUBATION. 49 

to you here of conflnent, seuii-coDlluent, corymbose, 
distinct, and modified small pox — of superficial, cellu- 
lar, and tracheal small pox — of the benignant, niahg- 
nant. and petechial small pox — of simple and compli- 
cated small pox. 

Every kind and variety of small pox is divisible into 
iuee stages — incubation, maturation, and decline. 

1. Of the period of iucuhation. This is the latent 
or dormant period of some autliors, and it includes the 
whole period tbat elapses from the reception of the 
variolous germ to the development of eruption. The 
first few days are passed, in many instances, without 
symptoms of any kind, hut in other cases there are 
obvious evidences of some morbid process going for- 
ward. At the moment of receiving the miasm, the 
patient experiences, perhaps, an unpleasant odor, or a 
feeling of sickness, or of giddiness, or of inward alarm. 
As the incubation advances, his nights are restless, bis 
spirits low. He is oppressed with languor and lassi- 
tude. With respect to the period of incubation, a large 
accumulation of facts enables me to fix it at twelve 
days of apyrexia and two of fever — fourteen in all. 
One example may suffice. 

Mrs. Joseph, wife of Mr. Joseph, surgeon, of Great 
Marylebone street, registrar of biribs and deaths for the 
Kectory district of Marylebone, was sitting in her parlor 
on Monday, June 7, 1841, when a nurse called to 
register the death of a child who had died the preced- 
ing day of small pox. The nurse had just left the 
dead body. Mrs. Joseph's suspicions were sufficiently 
excited to induce her to have her baby vaccinated 
immedialely, but she never thought of herself. On 
Saturday, June 19 (thirteentli day from exposure to 



50 CHARACTER OF ERUPTIVE FEVER. 

the miasm), Mrs. Joseph sickened. On Monday, June 
21 (being that day fortnight on which the child's death 
had been registered), small pox appeared in her. 

The incubative period admits of some latitude. The 
extremes may perhaps be stated at ten and sixteen 
days. 

With regard to the initiatory or eruptive fever (con- 
stituting the last two days of the incubative period), it 
may be remarked, that on the twelfth or thirteenth day 
from imbibing the germ, rigors occur, followed by the 
usual evidences of pyrexia — a quickened pulse, heat of 
skin, pains of the back and limbs, scanty and high- 
colored urine, and restlessness. How can you prognos- 
ticate that the fever then breeding is variolous ? 

(1.) By the sickness at stomach. This is often very 
intense, continuing for two or more days, and often 
accompanied by tenderness of the epigastrium on pres- 
sure. There is irritability of the stomach here, but not 
inflammation, for the vomiting is uninfluenced by 
bleeding, and yields when the eruption shows itself 

[Heberden says, " if the vomiting be continued after the eruption is 
completed, the patient's life is in great danger, even though the small 
pox be not confluent," — Commentaries^ p. 355.] 

(2.) By the pain of the back and loins. This, too. 
Is often very intense, so that men carrying a load have 
dropped down in the street The most remarkable 
case of the kind which I ever saw was the following : 
— Mrs. Delahay (Little Marylebone Street), at the full 
time of her first confinement, began to complain, No- 
vember 23, 1837. The pain of the back was very 
severe, with very little intermission. Yet the os uteri 
scarcely dilated at all. Mr. Jordan, who attended her, 
seeing some peculiarity in the case, requested my assist- 



CHARACTER OP EHUPTITE FEVER. 

ance. The pain of the back was agonizing, and she 
continued to suffer from it during the whole of the 23d, 
the OS nteri contiouing unahered. She was put into 
the warm bath, took 200 drops of laudanum, and was 
bled to thirty ounces. At one a.m. on the morning of 
the 24th, she was delivered of a dead child, but pain 
still continued. On ihe evening of the same day, con- 
fluent small pox appeared, when the pain of the back 
ceased. She had been well vaccinated in early hfe. 

The peculiarity of this case consisted, you will per- 
ceive, in the incubative stage of small pox concurring 
with the completion of ntero-gestation. The infant's 
life was destroyed by the intensity of the fever. 



[Lumbftr pain is one of the moat common precursory Bymptotna of 
vnririla, and ofl«n of a groat degree of severity, and is not met with in 
either BcarlHtinn or rulMola, or at least to an atnouut at all marked, and 
ita presence often BBsists mnterially in the diagtiosis of this diseiiM. 
Beberden lays, " an excruciating pain in the luins has never failed to 
be succeeded by a bad sraall pox, and the more violent tile pain, the 
greater has been the danger ; it 'm much safer to have it between the 
sbonlders." — (Comnuntarieg, p. 354.) I have, bowever, seen a mild 
attactt of varioloid follov severe pain in tlie back, and the reverse of 
this is also true.] 

(3.) Encephalic symptoms accompany the initiatory 
fever of small pox in certain cases. Adults complain 
of severe headache. There is stupor or doHriuu). The 
face is flushed. The carotid and temporal arteries 
beat strongly. The patient is supposed to he on the 
eve of a severe cerebral affection. Somnolency or an 
epileptic fit is often noticed in children. 

(4.) Syncope and e.tcessive prostration of strength 
are the leading features in some cases. I have seen 
syncope occur on the seventh day after inoculation. 
Occasionally, even in strong habits, the effect of ihe 



52 DURATION OF ERUPTIVE FEVER. 

miasm is so thoroughly poisonoas that the coantenance 
turns pale, the pulse is feeble, the extremities become 
cold. The patient is brought into a state o{ collapse. 

(5.) Great anxiety of the praecordia, deep sighing, 
and dyspnoea (symptoms indicating thoracic conges- 
tion), are occasionally noticed. 

[** A great shortness of breath coming on about the fifth day of the 
eruption, scarcely leaves any hopes that the patient will sun'ive."— 
Heberden — Commentaries^ p. 357,] 

Sometimes the one, sometimes the other of these 
groups of symptoms predominates during the brief 
period of eruptive fever. In addition to the evidence 
which they afford, the suddenness of the seizure, the 
previous good health of the patient, the circumstance of 
prior exposure to the contagion, or having previously 
undergone small pox, will assist in the diagnosis. In 
adults, the fact of prior vaccination is not to throw you 
off your guard, for the initiatory fever is just as severe 
after vaccination as it is in the unprotected. 

The eruptive fever of small pox acknowledges the 
tertian type. Forty-eight hours elapse from the rigor 
to the first appearance of eruption. Sydenham believed 
that the more time nature occupied in finishing the 
separation of the inflamed particles, the greater was the 
chance of ultimate safety to the patient ; and accord- 
ingly he never interfered at this period. Before his. 
time, the theory and practice were different. It was 
thought that nature was struggling to effect the separa- 
tion, that she required assistance to do this effectually, 
which assistance was afforded to her in the shape of 
heating diaphoretics and alexipharmics. 

The duration of the eruptive fever is never less than 
forty-eight hours. It may be protracted, by weakness 



CRABACTBA OF THE ESUPTIOff. 

of habit, to seventy-two hours, anil the full development 
of eruption over the whole surface may even occupy 
three couiplete days. Minute papulx sensibly elevated 
abave the surface of the skin show themselves, iu the 
first instauce, on the face, forehead, and wrists. In a 
few instances only does the eniption commence on the 
lower extremities. It often happens that two or three 
large papulae precede the general eruption, and advance 
to the slate of vesicle, before the surface is extensively 
occupied. 

[Tlie first pustules are usually seen on the upper lip, cheeks, and 
forehead, but tliey are often found on the velum palati sooner than on 
any other part. Hence it is always important to enamine the inside of 
the mouth and the throat, when this disease is suspected, to aid in the 
diagnosis. Sometimes the paria are inflamed witliout any perceptible 
eruption; at other times, both inBamroation and papulx can be 
plainly seen.] 

In a large proportion of cases, the outbreak of erup- 
tion affords great relief to the general constitutional dis- 
turbance. The fever moderates, the sickness abates, 
the dorsal pains diminish, the head is relieved. From 
all this, you will perceive that such symptoms depend, 
not on inflammation, hut on vas ular distension. 

Something may be learned by attention to the 
arrangement of the papulfe. They are not thrown 
together confusedly and without order, but are arranged 
in groups of three or five. Crescents and circles may 
be traced very distinctly when the eruption is not too 
copious. This constitutes an important diagnostic 
between variola and varicella. 

The external character and internal structure of the 
variolous pimple and pustule have excited much atten- 
tion. Cotuguo, in Italy, commenced the investigation. 



54 ORGANIZATION OF THE PUSTULE. 

which John Hanter, Dr. Adams, and, in more recent 
times, Bousquet, Gendrin, Mr. Judd, Dr. Petzholdt, and 
others have continued. 

[To the names quoted by our author of those who have investigated 
the structure of the small pox pustule, may be added that of Dr. Simon, 
who has given a minute description of its peculiarities in his work on 
diseases of the skin, a full abstract of which may be found in the Brit, 
and For, Med. Ckir, Rev., April, 1849, p. 349.] 

The organization of the variolous pustule is very 
curious. Inflammation begins at a spot called the 
phlyctidium. Its seat is in the cutis vera. From the 
central point, or stigma, the inflammatory action pro- 
ceeds by radiation on the surface, penetrating to a 
greater or less depth in different cases. Beneath the 
epidermis, and constituting the greater part of the 
phlyctidium, is found a substance, or disc, of the con- 
sistence of pulp or thick mucus. This is not considered 
as any part of the skin altered by disease, but as the 
product of a specific action of the vessels. John Hunter 
and Adams called it the variolous slough. At the 
height of suppuration this substance is swollen, and 
moist like a sponge. The floor of each phlyctidium 
presents the papillated structure of the skin, elevated, 
and marked with fissures. The vesicle is divided, like 
the substance of an orange or poppy-head, into nume- 
rous cells (twelve, or more). It is, as we say, multilo- 
cular. A filament of cellular tissue binds down the 
central portions of cuticle to the lower surface of the 
phlyctidium, and gives to the vesicle, in its early stages, 
that umbilicated form, that depression of its centre, 
which, though not peculiar to the variolous eruption, is 
so important as a diagnostic mark between it and genu- 
ine varicella. The fluids (lymph and pus) which at 



MATUEATIVE STAGE. 



different periods distend its cells, desiro}' at length tlie 
filamcutous attachment of the stigma to tlie cuticle, and 
that which was at first a depressed or uiiibilicated vesi- 
cle, becomes at last an acuminated pustule. It bursts, 
discharging a well formed purulent matter, of a yellow- 
ish color and creamy consistence. 

2. The inflammation of the phlyctidium is accompa- 
nied by a kind of erythema, or specific inflammation, 
called tlie areola, extending to some distance beyond 
the margin of the vesicle. The color of the areola is 
always to he carefully noted, for reasons which will 
soon be e.\plaincd. On the subsidence of this inflam- 
matory areola, the ripened pustules, having burst and 
discharged their contents, are succeeded by scabs, which 
dry up, and, in a healthy state of constitution, fall off ui 
four or five days. In mild cases, where the full process 
of pustulation is not gone through, many of the vesicles 
shrivel, and form only tubercles, or imperfect scaly 
crusts. On the lower extremities, this premature desic- 
cation of the vesicles is often very general. 

In severe cases, the infiammation of the corion does 
not cease with the completion of the pustulating process. 
Portions of the cutis vera are then actually destroyed 
and slough away, the result being that, when cicatriza- 
tion is at length completed, tlie skin presents the ap- 
pearance of pits or fovcie, with a diffused clarety hue of 
the surface. This tint wears off in the course of three 
or four months; but the depressions are permanent. 
From the great vascularity of the face, there is always 
most risk of such disfigurement there. 

Nurses will talk to you of a five, six, seven, eight, 
nine, and even ten days' pock. They are quite right

interfered with by any peculiarity of habit either con- 
genite or acquired by previous vaccination, — when the 
constitution is sound, with sufficient strength of system, 
and a good, but not over-abundant supply of blood, — 
lastly, when there is not too copious a crop on the sur- 
face, the pock maturates in seven days. In severe cases 
of a semi-confluent or corymbose kind, the process of 
maturation occupies eight days. In bad confluent 
cases, nine or perhaps ten. On the other hand, after 
vaccination, or when there is some originally favorable 
diathesis present, the pock will maturate in six, or some- 
times imperfectly in five days. This five-day pock 
constitutes the mild, mitigated, or modified form of 
variola, now so familiar to us, as occurring in those who 
in early Ufe had been well vaccinated. But this variety 
of the disease, though formerly less frequent, was yet 
well known to all the old authors. Van Swieten 
describes it under the title of variola verrucosa and 
cornea (stone pock, horn pock, and wart pock). 

A certain amount of fever accompanies the matura- 
tion of the pock even in its mildest aspects. The actual 
amount depends mainly on the quantity of eruption, but 
something is attributable to the habit of tlie patient, 
whether irritable or otherwise. A quiet condition of 
mind is always favorable to small pox. Something de- 
pends, too, upon season, something on diet, and the 
temperature of the room in which the patient lives. 
The corymbose, or partially confluent form of small 
pox (where the vesicles are grouped into clusters, leav- 
ing intermediate spaces of unoccupied skin), is always 
attended with severe and irregular fever. 

The maturative process is often accompanied by an 
exceedingly tender state of the surface. This happens 



chiefly in women, and in men of delicate skin. It is a 
very farorable sign, tliougii productive of much tempo- 
rary inconvenience. The variolons matter, when 
abundant, gives off a peculiar, faint, and sickly odor. 
Kecovery may be retarded, even in the distinct small 
pox, by weakness of habit, by cold, and ihe excitation 
of scrofulous disease. Ecthymatous eniption may then 
occupy the surface ; the skin maybe left dry and scaly; 
the scabs may be adherent. All this is owing to the 
setting up of a low form of secondary fever. 

I nmst next draw your attention to the implication 
of certain of the mucous structures in the progress of 
small pox. In a lai^e proportion of confluent, and in 
some semi-confluent cases, the mucous membrane of all 
those parts to which the atmospheric air gets access 
(the nose, month, and trachea), is occupied with erup- 
tion — sometimes distinct, more generally confluent. 
The early symptoms occasioned by tliis mucous com- 
plication arc as follows: — Numerous white points appear 
on the tongue, palate, and velum pendulum. Hoarse- 
ness and alteration of voice indicate that the same con- 
dition exleitds to the nmcous membrane of the larynx 
and trachea. There is great pain in swallowing, and 
in bad cases cough and dyspncea. The cough is at 
first dry and tearing. As the disease progresses, there 
is expectoration. About the eighth day, a copious 
viscid secretion takes place from all the atrected stnic- 
tures. 

The nlterior effects of this mucous implication are 
far more important than any local mischief \vhich it 
occasions. The oedematous thickening of the larynx 
and the swollen condition of the tracheal membrane, 
have by the eighth day maierially impeded the free

access of air to the iangs, and the consequences appear 
in every part of the circulating system. There is no 
crimson areola, for the blood is not well arterialized. 
The vesicles on the extremities never acquire any 
inflammatory areola, by which alone the surface can 
be cicatrized. On the trunk the areola is dark or 
claret-colored. The vesicles do not acuminate. They 
lie flat, and present much of the same appearance which 
is displayed after death. Sometimes the superficial 
inflammation partakes more of an erysipelatous than of 
a phlegmonous character. The results are large watery 
blebs, from which flows out a thin ichor. Consequences 
still more serious happen in the succeeding twenty-four 
hours. The brain becomes affected. A low muttering 
delirium is observed, as the waves of ill oxygenated 
blood begin to circulate. The tongue swells and exhi- 
bits a purple hue. Restlessness and great anxiety suc- 
ceed. The patient tries to get out of bed. The 
bladder loses its contractile power, and may be felt dis- 
tended at the brim of the pelvis. The extremities 
become cold. Dyspnoea increases, and the patient 
dies ! 

[According to M. Louis, fifteen twentieths of all that die of variola, 
perish from asphyxia consequent upon affections of the larynx and air 
passages generally. 

For an interesting paper on this subject, with cases confirmatory of 
this remark, by Charles R. King, M. D., see N, Y, Journ.of Med. and 
Surgery, April, 1840, p. 269. 

The present state of our knowledge respecting cedema glottidis, sug- 
gests the inquiry, whether this state of the parts in variola may not be 
the cause of the sudden fatality of a certain number of cases, and if this 
be the case, whether the operation proposed for its rt^lief by I>r. G. 
Buck of this city, might not be practised with benefit. For an account 
of this operation, with illustrative plates, see Trans. Amer. Med. Asso- 
ciation^ vol. i. p. 135.] 



CONSEQUENCES OP SECONDARY FEVER. bH 

The implicatiou of the cellular membrane in the 
progress of small pox must next engage our attention. 
In the distinct small pox the skin continues movable on 
the subjacent textures, hut ia all bad cases, confluent, 
semi -con fluent, and cor^'mbose, the inflammatory actiOD 
dips deeper, and invades the cellular membrane. The 
skin DOW becomes swollen and tense. This cellular 
complication is sometimes universal, sometimes partial. 
The scalp is very often affected. Enormous intumes- 
cence takes place, followed by diffuse pustulation, or a 
succession of small and most troublesome abscesses. The 
cellular membrane of the throat is peculiarly liable to 
take on this action. The salivary glands participate in 
the inflammation, and salivation \vlth great turgescence 
of die neck follows. Occasionally the tongue becomes 
involved. Glossitis is superadded to other evils, and 
few, if any, survive, when matters have proceeded to 
this extremity. Supposing, however, tliat neither the 
cellular nor laryngeal inflammation is in sufficient 
intensity, on the eighth or ninth day, to destroy the 
patient, then secondary fever sets in, to be known at all 
times by the occurrence of rigors, followed by a hot and 
dry state of the surface, and a thirst unquenchable. 

3. In the progress of secondary fever you must be 
prepared for all sorts of troubles. The skin, already 
weakened and prone to inflammation, is sure to suffer 
first. The elbows, legs, scrotum, knees, back, and hips, 
take on a mixed erysipelatous and phlegmonous action. 
Tbe result is either boils and abscesses, or enormous 
imposthumes, or carbuncles, and gangrenous destruction 
of large portions of tbe skin, according to the severity of 
each case. On the 17th July, 1829, 1 saw at the Small 
Pox Hospital an exact counterpart of the pestilential 



60 MODIFIED VARIOLA. 

babo and carbuncle on the groin of a small pox patient 
Sometimes the whole surface of the body is covered with 
a vivid scarlatinal rash. The face always suffers severely 
in this aggravated form of cellular small pox, and the 
patient (if happily he escapes) passes through a tedious 
process of convalescence. In 1828 I saw a woman 
whose face was not simply pitted, but scored and seamed, 
She informed me that she was twelve years in recovering, 
and I could well believe it. The disposition in inflamed 
parts, during the secondary fever of small pox, to termi- 
nate in suppuration, appears to be universal, and almost 
uncontrollable. In some few cases the larger joints fill 
with purulent matter. 

Confluent and semi-confluent cases of small pox, 
though very frequently, are not necessarily accompanied 
with cellular complication. There is a form of the dis- 
ease called the confluent superficial^ where the eruption 
passes through all its regular stages, but the inflamma- 
tory action never extends beyond the outer layer of the 
corion. This is sometimes confounded with the modi- 
fied small pox, but the progress of eruption is very 
different in the two cases. The confluent superficial 
small pox appears in the unvaccinated. The pustules 
maturate equally and regularly. The confluent modified 
small pox, on the other hand, never appears except in 
the vaccinated, and the advance of the pustules is not 
only imperfect, but it is unequal on the same portion of 
surface. On the arm, for instance, at one and the same 
time, you will perceive some pustules fully maturated, 
others of smaller size desiccating after the escape of a 
minute portion of pus, while part of the eruption has 
become tuberculated without purulent formation, and 
with little or no surrounding inflammation. This ine-

quality of aspect is the great cliaracleristic of modified 
variola. 

I must next draw your attention to tlie implication of 
tlie brain and nervous system in tlie plienomena of small 
pox. Children grind tlieir teetli, and squint. Cerebral 
intlammation supervenes and the child dies, either in an 
epileptic fit, or with evident signs of hydrocephalus. 
Adults become delirious, and octasioually it is of that 
severe kind called delirium feroz, accompanied with 
great wildness of the eye, and sucli strong tendency to 
self-destruction that the utmost precautions do not over- 
step the necessities of the case. Variolous delirium 
depends more on some peculiarity of temperament, on 
some highly irritable condition of the nervous system, 
than it does on inflammation. Thomas Weston became 
a patient of the Small Pox Hospital on the 17lh of July, 
]8:?9. For several jears his thoughts had been alisorbed 
in religious matters. He would often say that he was 
better prepared to die then than he could he if bis life 
were lengthened. When it was announced to him that 
his complaint was small pox, he expressed no wish to 
recover. The eruption was uioderate in quantity — not, 
per se, threatening danger. He had been vaccinated in 
early life. Delirium set in early, and he died on the 
eighth day of the disease. A peculiar nervous affection 
often supervenes on the tenth day, when tlie skin is 
extensively occupied by the confluent eruption without 
nervous complication. It is identical with that which 
is familiar to surgeons as the consequence of extensive 
burns and scalds. General tremors, low delirium, a 
quick and tremulous pulse, a dry tou^^ue, collapse of the 
features, cold extremities, and subsultus tendinum, are 



62 PETECHIAL SMALL POX. 

the symptoms of this nervous complication, and the pre- 
cursors of a fatal event. 

The implication of the fluids next demands notice. 
It happens occasionally, though happily not often, that 
the miasm of small pox poisons die blood, alters its 
crasis or coagulating properties, and leads to haemor- 
rhages from every open surface. The evidences of this 
condition of the fluids are often perceptible from the 
first hour of initiatory fever. At other times they are 
not noticed until the eruption has begun to develope 
itself, or even later in the maturative stage. The erup- 
tion has a livid or dingy aspect. The expression of the 
countenance is highly anxious. If blood be drawn from 
the arm, a loose layer of fibrine is thrown up, beneath 
which you find fluid red blood. Haemorrhage takes 
place from the nose, mouth, lungs, stomach, bowels, and 
kidney. Petechiae and patches of ecchymosis (called 
vibices) appear intermixed with the variolous papulae. 
The variolous vesicles fill with blood, instead of serum. 
The aspect of body in some cases of aggravated pete- 
chial small pox is wholly changed. 

In February, 1842, 1 saw, in consultation with Dr. L. 
Stewart, a lady in small pox, whose whole body was of 
the color of indigo, and whom I at first believed to be a 
native of Africa. She conversed with me in the most 
tranquil manner, and died a few hours afterwards, 
proving that the nervous system is not necessarily, nor 
is it even usually, implicated in the petechial form of 
small pox. 

When adult females are thus attacked, menorrhagia 
is almost always observed, and if they be pregnant, 
abortion or premature delivery takes place. The fcetos, 
as you might naturally expect, dies in utero. 



PETECRIAL SMALL FOX— GANGRENE. 

[Heberden says [Commenlaries, p. 35E) that in the worat cases of 
emtill pox, the menstrual discharge has come on out of its regular course 
two days before the small po* liaa begun to show ilaelf, and has con- 
tinued to flov in an excessive manner, and that it has sometimei 
appeared before ita regular lime, ti^tlier with the eruption ; but that 
more commonly it has begun as soon as the eruption nss completed, 
and continued from one day to five. The discbarge does not check the 
progre-M of the small pox, nor depress the patient's strength, and 
requires no interference from art. The pn^oais, however, is entirely 
di9i;rcnt. and of a very serious character, when there is a complication 
with purpura, attendetl with hemorrhages from other parts, Socb cases 
are almost always fatal. 

The period at which miscarriage tatiea place is usually at the time of 
suppuration of the pustules, which is about the seventh or eighth day 
from the Rntl enip^on, a day or two afU.-r whieh death more commonly 
occurs. A case, however, is related byDr. Marrotte{ffaz. <i«s Hdpitaax, 
Sept. 5, 1S46), in a woman 26 years old, who aborted in the fourth 
month, five days after the complete desiccation of the variolous pustules, 
and without any external cause. The ftetus presented no trace of erup- 
tion, which is moat usually the case, A small proportion pass ihrougi 
the disease without miscarrj'ing.] 

This variety of small pox was known of old by the 
uaine of ibe black pox (variolae nigrfe), and appears to 
have been more frequent in former times than it is now. 
Death may take place in consequence of this remarkable 
condilion of the blood before any unequivocal signs of 
small pox are developed. More commonly, the erup- 
tion, confluent iu character, displays itself, but never 
makes much advance. Nature apparently gives up the 
struggle as hopeless. The patient is carried oJT very 
unexpectedly, perhaps on the fourth, or from that to the 
sixth day. 

There is something not very well understood in the 
coDcurrencc of gangrene with small pox. It is not 
necessarily connected with the petechial state, nor with 
affection of the nervous system, nor with debility. It

often occurs where the fever is of a truly inflammatory 
type, and where no previous symptom gave evidence of 
unusual danger. It is more generally found attendant 
on the irregular or corymbose small pox than on the 
purely confluent cases. The chief seats of variolous 
gangrene are the scrotum, feet, and back, but I have 
seen it also on the breast 1 cannot doubt but that in 
certain cases the gangrenous disposition is something 
superadded to the small pox by the condition of the air 
which the patient breathes. 

Small pox is often accompanied with ophthalmia. It 
has been stated that this arises from the formation of 
pustules on the cornea and conjunctival membrane. 
This is erroneous. If these structures had been sus- 
ceptible of the specific variolous eruption, every con- 
fluent case must necessarily have ended in total blind- 
ness ; but, happily, Nature has arranged it otherwise. 
Conjunctival inflammation, iritis, inflammation still 
deeper seated, may indeed arise, especially when exten- 
sive crusts put a stop to all perspiration, and when 
secondary fever rages in the blood, and devastates 
internal organs. But there is no specific inflammation 
of the eye in small pox. 

The ophthalmia by which so many eyes have been 
lost is a sequela of the disease, generally coincident 
with some great destruction of surface in a distant part. 
In some cases, variolous ophthalmia, setting in on the 
tenth day of the disease, advances so rapidly, that in 
forty-eight hours the whole eyeball is irremediably 
injured. I have seen the whole eye converted into 
one large abscess. More usually, the inflammation runs 
into some of its less violent and more familiar conse- 
quences. An ulcer forms at the outer edge of the cor-

nea, by which tlie aqueous humor escapes, or at which 
staph) lorn ato us protrusion of the iris takes place ; or 
the aqueous humor becomes clouded, or specks form on 
the cornea, from wliich blindness more or less com- 
plete, more or less permanent, results. 

Although, at present, we are not in a position to 
affirm it positively, yet many facts concm' to render it 
almost certain, that this secondary affection of the eye 
in small pox is connected with and dependent upon 
some altered condition of the blood — certain matters 
being retained within it which ought to have been 
chminatcd. 

It would be unreasonable to believe that such a fever 
as I have described should rage, expend its whole viru- 
lence on the skin, and never affect the great internal 
organs of the chest and abdomen. Sronchial infiam- 
mation is sometimes present daring the wliole course of 
the complaint, especially in the winter season, bat it 
docs not materially complicate the phenomena. In 
Lascars, and all natives of tropical climates, attacked 
by small pox in a cold chmate, this frequently happens, 
and may of itself prove the cause of death. Sometimes, 
even among our own people, the substance of the lungs 
becomes involved in Indannnation, and its usual conse- 
qneoces. But the great peculiarity deserving of your 
notice is the frequency of variolous pleurisy. It occurs 
between the twelfth and twentieth day. It is a pera- 
cutc form of inflammation, remarkable for its sudden 
invasion, rapid progress, and invariable termination by 
empyema. The symptoms are very unequivocal. 
Intense pain, a hard, wiry, and incompressible pulse, 
shortness of breathing, and a dry state of the surface,

betoken but too forcibly the state of the pleura. Blood- 
letting is almost powerless in this disease. Death usu- 
* ally happens on the third, or, at furthest, on the fourth 
day, from the invasion of thoracic symptoms. The 
heart occasionally becomes involved. Syncope, palpi- 
tation, and a sense of exhaustion, are the evidences of 
this complication. I have seen such symptoms con- 
current with phlegmasia dolens of the leg, indicating an 
inflammatory condition of the blood-vessels. These 
cases prove fatal very rapidly. 

Small pox is singularly exempt from all abdominal 
complication. Children sometimes fall into a state of 
mucous enteritis, with frequent, slimy motions, and 
emaciation ; but nothing occurs here to warrant me ia 
detaining you. 

The appearances, on dissection, peculiar to small 
pox, are confined to those which the larynx and tra- 
chea exhibit. The lungs, indeed, sometimes display 
the usual evidences of inflammation — vascular engorge- 
ment, purulent infiltration, and hepatization. The 
thorax of one side may be found replete with a sero- 
purulent fluid (resembling a mixture of cream and 
water), the result of acute pleurisy, and the pleura itself 
may be seen injected with blood, and covered with a 
dense layer of coagulable lymph ; but all this occurs 
equally in other diseases. The condition of the larynx 
and trachea, however, in small pox, on the eighth day, 
is unique. The mucous membrane, if then inspected, 
appears covered with a copious, viscid, puriform secre- 
tion, of a grey or brownish color. On detaching this, 
the membrane itself is seen deeply congested with 
blood, thickened, pulpy, and, in the worst cases, black

and sloughy, exhaling a uiost offensive odor. Tlicse 
appearances may be traced to the third division of the 
bronchial tubes. 

Much discussion has taken place regarding the 
occurrence of variolous pustules on the gastro-cnteric 
mucous membrane. Cotugno, Wrisberg, Iteil, and 
others, who have paid great attention to the subject, 
concur in opinion that this structure is not capable of 
developing them. Sir Gilbert Blane, again, reports a 
case where the mucous membrane of the bowels pre- 
sented the appearance of ulcerated spots, which he 
compared to variolous pustules. The experience of 
the Small Pox Hospital is in favor of the old doctrine. 
Inflamed, enlarged, aud ulcerated follicles, wilh pete- 
chial patches, may indeed be noticed in a few rare 
cases ; but such appearances are in all respects the 
same with those observable in typhoid fever. 

[PathologUto seem to be divided in opinion as to llie existence of 
true varioloiia paslules on tlio niucoua luembraue of ihe intes^nnl canal, 
Louis, Gerhurd, MM. BurtheE and Rilliet, Petzholdt, and Chaptnan,

evor prewnt there, and saying that a follicular eruption, not untrequenlly 
ibund both at the beginning and end of the small intestine, and more 
rsrely in the lai^ intestine, has given riae to llie error. 

Dr. George Patterson, however, of Edinburgh, lately reported a case 
of a boy, five years old, in which pustules and superficial incrustations 
were found in the lower part of the intestines, and the statement is 
corroborated by Dr. W. T. Gairdner, who made tlie pcntriuorleni exami- 
nation with Dr. Patterson. The whole case was so well characterized, 
that he considered it as an unequivocal instance of varioloid eruption in 
the coloD. 

M. Rostan is also quoted aa authority in favor of their having been 
found throughout the whole intestiniil tract.] 

In like manner, the brain presents, in small pox, no 
morbid phenomena different from those which other 
types of fever display.

In the present lecture I propose to bring before you, in 
one view, the several considerations which reflection on 
the phenomena of small pox is calculated to elicit 
Everything that relates to diagnosis, statistics, and the 
origin of the disorder, comes therefore now to be inves- 
tigated. To distinguish one disease, however, from 
another, it is obviously requisite that the course of both 
should be known. We are therefore hardly in a situa- 
tion yet to enter with advantage on this topic of inquiry. 
Nevertheless, that nothing may be omitted which can 
contribute to your practical benefit, I will say a few 
words on the diagnosis of small pox. 

The diseases with which, after the occurrence of 
eruptive fever, small pox may be confounded, are 
measles, febrile lichen, varicella, and secondary syphilis. 

J. The papula; of small pox are firmer than those of 
measles. They feel granular under the finger. In 
measles, too, there are accompanying cough and watering 
of the eyes. Furtlier, in small pox, forty-eight hoars 
elapse from rigor to eruption ; in measles, seventy-two. 



DIAGNOSIS OF SHALL POX. 

2. Febrile Uchen is the disease from which small 
pox, at its onset. Is \vith most difficulty distiuguisbed. 
The aspect of eruplion is in both cases nearly aUke. 
The surest and safest grounds of diagnosis are based ou 
the interval which has elapsed from rigor to eniptioa, 
and the mode in which ihe eruplion has developed 
itself. In febrile lichen, tweniy-fonr hours elapse from 
sickening to eruption ; in small pox, as you know, 
forty-eight Small pox almost always appears first on 
the face. The eruplion of lichen is developed, from the 
first, uniformly over the head and trunk. Besides 
which, your judgment will be materially aided by 
inqnirles into the prior history of the patient, and the 
character and course of incubation. 

pn febrile lichen, the gastric derangemeDt would probably be greater, 
aldiougli witbout vomiting, there would be no puis in die back, and 
the itching would be so marked as to form a prominent symptom. 
The early appearance of piutules on the velum and palatine arehea has 
abo assisted me in the diagnosis. At the same time I would add, that 
tbU form of lichen, presenting such a resemblance to small pox as to 
give rise U> uncertainty in the diagnosis between the two diseases, has 
seldom come under jny observation, and cannot be of very frequent 
occurrence amongst us.] 

3. The diagnosis of small pox and chicken pox 
requires attention to uiiuutia:, and cannot be given until 
a later period of the course, when the plienumcna of 
that mild disorder will be duly submitted to you. 

4. There is a form of secondary syphilis, in which 
an eruption appears on the face and tnink very similar 
to the distinct small pox. This syphilitic eruption 
passes through the several grades of papula, vesicle, and 
pustule. It is preceded by a febrile attack of variable 
duration. The diagnosis is to be effected bj» careful 
inquiry into the whole history of the case, and close

observation of the progress of the disease. To those 
accustomed to the look of small pox, there is something 
in the general aspect of a syphiUtic patient, in the 
absence of all febrile anxiety, which would at once 
indicate that the generating miasm was not variolous. 
The march of the disorder would convert suspicion 
into certainty. The pustular syphilitic eruption runs a 
tedious course, exceeding ten days. The pustules are 
developed, not simultaneously, as in small pox, but in 
successive crops. 

[Dr. Watson mentions one patient under his care, in whom " the 
papulsc of small }>ox were, at the ouUet, so intermingled with the 
appearances and sensations of urlicaria, that he doubted, for twenty* 
four hours, what the true character of the eruption might be." — {Prac, 
ofPhys,, p. 978; 3d edit, 1847.)] 

From the earhcst periods, much attention has been 
paid to the statistics of small pox. The absolute num- 
bers carried off by it, and the relative numbers of those 
who die to those who are attacked, have alike been 
made the objects of inquiry. The old bills of mortality, 
which can be trusted to more in plague and small pox 
than in any other disorder, give 199,605 as the total 
amount of deaths by small pox in London during the 
last century, of whom 97,546 perished in the first half, 
and 102,119 in the second half During the last quar- 
ter of the last century, from 1775 to 1800 — that is, 
prior to the discovery of vaccination, — the proportion 
of the mortality by small pox to the total mortality, was 
as 8 to 100 in London, and we may reasonably con- 
clude that the same proportion existed throughout the 
country^ Sir Gilbert Blane and others fancied that 
this ratio was steadily augmenting in consequence of

the spread of inoculation, but I shall show you after- 
wards that this notion was unfounded. 

All authors have remarked, that the greatest mor- 
taUty by small pox takes place in the early periods of 
life. Dr. Haygarth computed, that at Chester, in 1795, 
one half of the deaths among children below ten years 
of age was due to small pox. The same law holds 
good at present. From particulars to be found in Mr. 
Farr's first and second reports, I have drawn up the 
following table, which shows that out of every nine 
persons who now die of small pox in England, seven 
are below the age of five years.

In Ireland, during the ten years ending June 6, 1841, of 58,006 
deaths from this disease, 40,038 wore in those under five years of age. 

The statistics of Manchester, Liverpool, Edinburgh, Glasgow, Perth, 
and Dundee, for 1830, show that the rate of mortality by small pox 
during tliat year was from 85 to 89 per cent of those under fire yeais 
old. 

The following table by Dr. Watt, of Glasgow, showing the per

It will bo seen by this, that the proportion of deaths by small pox in 
New York and Thiladt'lphia, under two years of age, is above 23 per 
cent less than in Glasgow ; while there is a corresponding increase in 
the proportion of deaths at tbe higher ages ; while the proportion of 
deaths at the early ages is the same in these two American cities- Dr. 
W. considers it highly probable that inattention to early vaccination 
may Ix; the immediate cause of a greater mortality at tlie higher ages 
in Amcricji tlmn in Great Britain. {^Auur, Jour, Med. Sciaice, April, 
1845— p. 515.)] 

When the registrar-general of England first began 
his labors (July I, 1837), it was found that, notwith- 
standing ihc benefits of vaccination, there were still 
only four diseases which stood before small pox with 



MORTALITY OF SHALL POK. 



reference to the actual amount of mortality. Those 
still uiorc fatal complaints were — consumption, convnl- 
sions, typhus fever, and pneumonia. In the second 
half of 1837 there died, throughout England and 
Wales, by small po.\, 5811 ; and in the metropolis, 763. 
The year 1838 was remarkable for the epidemic preva- 
lence of small pox throughout this country. In that 
year there died by small pox in England and Wales 
no less than 16,268 persons, of whom 3817 died in 
London. In 1839, a marked diminution took place. 
The deaths over the whole country amounted only to 
9131, and in the metropolis to 634, which, as com- 
pared to the total mortahty in that year, is little more 
than 3 in 100. 

At the Small Fox Hospital, the admissions, from 
1776 to 1800 (a period of twenty-five years), were 
7017 — and the deaths 2277, being at the average rate 
of thirty-two and a half per cent From 1801 to 1825 
(a like period), the admissions were 3743, and the 
deaths 1118, being at tlie average rate of thirty per 
cent, of those attacked. Since 1825, the proportion of 
deaths to admissions has experienced a further diminu- 
tion. At the present time the deaths do not exceed 
twenty-five per cent, and in some years they have 
lallen as low as twenty per cent., or one in five. Tak- 
ing the world throughout, and making allowance for 
the character of cases which are usually sent to a 
hospital, we may state the average mortality by small 
pox at one in six of those attacked. Now this is 
exactly the calculation made by Dr. Adams thirty-five 
years ago, when he said that small pox occasioned very 
nearly a double decimation. 

The proportion of severe to mild cases is a subject

which merits attention. The following tahle, which

In tiic foregoing table it will be perceived that the 
vaccinated and unvaccinated are classed together, the 
object of the table being to show the proportion which 
the mild Ijear to the severe cases, without reference to 
the cause of such discrepancies. It will also be seen that 
the conlliicnt and semi-confluent cases taken together 
exceed tlie half of the admissions; that nearly one half 
of the conlluent cases prove fatal, and about one in ten 
of the semi-confluent cases. Tliedeatlisiu the remain- 
ing classes are to be looked upon only as accidental and 
superadded events. 

The next table that I lay before you carries the 
analysis still further, and shows ihe comparative severity 
of the cases, as they occurred among vaccinated and 
unvaccinated subjects. This table 1 have given for one 
year only, 1838, the year of epidemic prevalence.

This table shows how remarkable is the power of 
vacciuatioti in altering the proponion of severe to mild 
cases. It will be seen that among 396 unprotected 
cases, there were onlj' 23 which were mild in their 
aspect ; while out of 298 vaccinated subjects, there were 
no less than 134 which presented, from the onset, favor- 
able appearances, independent of GG, which displayed 
modification during the maturatlve stage. 

The next point which merits attention is the period 
of disease at which death takes place. Small pox may 
prove fatal at any period from the first invasion of fever 
to the fortieth day. Death may even take place prior 
to the development of eruption, but such cases are rare. 
In all countries it is observed that the second week is 
that which exhibits the greatest amount of mortality, 
and the eighth day the day of greatest danger. The 



76

subjoined table, extracted from the records of the Small 
Pox Hospital for 1828-9, shows the period of eruption 
at which 168 patients died. The dates of their decease 
prove satisfactorily that no importance can be attached 
to the doctrine of critical days in the fever of small pox.

It may be useful, in connexion with these statistical 
details, to recall to your recollection the principal cir- 
cumstances to which the fatal event in small pox is more 
immediately attributable. 1. Prior to the maturation 
of the pustules (that is, during the first week), small pox 
proves fatal by that general derangement of the whole 
system, and more especially of its fluids, which we 
usually designate by the term, acute malignaricy. No 
marked lesion of any internal organ would be traced on 



DIRECT CADBES OP DEATH. 

dissectioD. 2. During the second week of eruption, the 
chief cause of death will be found in the specific affec- 
tion of the trachea and larynx, and consequent asphyxia. 
3. During the third week, when secondary fever has 
begun its work of devastation, death may happen, either 
by effusion on the brain (hydrocephalus), or by super- 
vening pleurisy, pneumonia, or laryngitis, or lastly, hy 
gangrenous destruction of portions of the skin. During 
the 4th and subsequent week, death may he the direct 
consequence of erysipelas, or of some other complaint 
excited by the small pox, or engendered by that debility 
which small pox, in any of its severer forms, so frequently 
entails. 

[M. Trousseau remarked, in speaking of a p«-se of death from discreta 
Tariola, that the exflctness of a rule given hy Sydenham, an<l repeated 
after liim by Von Swieten & Stoll, was verified in it, vii. that when 
there is no tumefaction of the face and eyelid?i in variola, death takes 
place on the 9th or lOLh day if tlie disease U discrete, and on the 13th 
or 14th if it is confluent. (Clin. de» B6p. det EafanU ; quolrd hy Lon- 
don Laiii-et. American Republication, May, 1848, p. 441;.)] 

The phenomena and statistics of small pox being now 
described, I proceed to explain to you its causes, — to 
unfold what is known regarding its origin and mode of 
propagation, and the circumstances nnder which It com- 
monly displays itself. This we call the pathology of 
the disease, by which is understood everything that can 
be learned concerning a disease by reasoning upon 
acknowledged phenomena. 

For more than a thonsand years after tlie first appear- 
ance of small pox in Egypt, its causes were sought for 
in the condition of the blood, or in those circumstances 
of the body, or of the atmosphere which surrounds the 
body, which were beheved, and justly too, to give rise 



80 SPONTANEOUS ORIGIN. 

that the variolai vaccina} originate spontaneously. lie says that it is 
not doubted by the farriers of that place, and that, in all the cases he 
has observed, he could never discover the probability of any other 
source. (Observations on Variol® Vaccinae. Trans. Provinc. Med, and 
Surg, Assoc,^ vol. viii. p. 300.) 

K the cow pox thus frequently originate, analogy would seem to offer 
strong reason in favor of a similar origin, at least occasionally, of the 
human small pox, which so closely resembles it 

It must be acknowledged respecting them all, and especially with 
reference to measles, scarlet fever, and hoojnng cough, that they some- 
times occur in such a manner and under such circumstances as almost 
to exclude the idea of contagion. 

A striking instance of a case of variola without obvious contagion, is 
given by Dr. Banks, of Lawrenceville (111.), in \)[iQ Philadelphia Medical 
JSxaminer, new series, vol. v. p. 519, from which it is quoted in the 
Brit, and For, Med, Chir, Rev,^ April, 1850, p. 533. The case pre- 
sents several points of interest. The editor of the Examiner refers also 
to two other cases, where the idea of contagion seemed to be out of the 
question.] 

To understand, therefore, the origin and propagation 
of small pox, you must view it, not only as a contagious, 
but as an epidemic disorder. And first, of the conta- 
gious origin of small pox. 

Contagious emanations are given off from the human 
body at every stage (.f small pox, from the first invasion 
of fever to the throwing off of the latest scabs. Heber- 
den and Haygarth believed that for the first few days, 
fiid during the initiatory fever, a patient seldom, if ever, 
communicated the infection ; but this notion is erro- 
neous. I have even been tempted to think that in the 
very earliest periods of the disease the communicating 
power is most energetic. 

[Heberden fixes the probable time of communication at the sixth day 
of the eruption. Chapman (Eruptive Fevers) agrees with Heberden, 
but thinks it probable that, as in tlie instance of the vaccine affection, 
the contagion may exist in the vesicle as well as in the pustule. 



PREDISPOSING CAUSES. 



frl 



Prof. A. Clark, of this cily, from a cnrefiil esnminalion of llie caaea 
vhich have occurred at the New York Ilospltal for a series of years, is of 
the opinion ibal the disease is not communicated until the eruption hai 
reached tlie vesicular form.] 

The dry scabs of small pox retain a conlaglons 
property for a great length of time. Ejtperience, too, 
has taught us that death does not destroy the energy of 
the purulent secretion, A child has been successfully 
inoculated with matter taken from the dead body. A 
confluent case will taint the air and spread infeciion for 
at least len or twelve days after death. The know- 
ledge of this fact has induced the Secretary of State to 
issue orders that the bodies of those dying of small pox 
are not to be admitted into the schools of anatomy. 

The circumslances that determine the quantity of 
eruption and the general character of the disease are 
not well known, though many attempts have been made 
to throw light on this obscure branch of exantheuiatic 
pathology. Notliing is belter ascertained than that the 
disorder produced bears no necessary relation to the 
disorder producing. A confluent case shall give origin 
to a varioloid, and a uiiid distinct, nay, even a varicel- 
loid, or highly modified case, shall generate in another 
person malignancy and confluence. The predisposition 
to the reception of the variolous germ is an interesting 
branch of this inquiry. Persons in the best health take 
small po.v, and, upon the whole, are more apt to take 
the disease than those who are out of health, just as we 
find it most easy to vaccinate successfully the ruddiest 
and finest children. The state of mind generally said 
to be most favorable to the reception of the virus is a 
dread of the disease. There is probably some truth in 
this statement, but you will meet with exceptions to the 



82 PREDISPOSING CAUSES. 

rule, almost as numerous as the illustrations of it. 
Change of air decidedly predisposes the body to receive 
infection. But this is a law of the animal economy of 
very wide application. It is this same principle, applied 
io endemic fevers, which leads to the phenomena of 
seasoning and accUmatization. You know that a regi- 
ment arriving in the West Indies, or the crew of a ves- 
sel first entering the Bonny or Calabar, are almost sure 
of suffering from the remittent fever of those climates. 

The quantity of eruption in any particular case is 
sensibly influenced by the state of the surface at the 
precise moment of development Whatever tends to 
augment the cutaneous circulation, such as the warm 
bath, abundant bed-clothes, strong diaphoretic and su- 
dorific medicines, cordials, wine, heat of the apartment, 
all concur in favoring confluence. The proved effect 
of heat in promoting, and of cold in repressing eruption, 
formed the keystone of the Suttonian practice of inocu- 
lation. Small pox is almost always confluent, and fre- 
quently fatal, when it occurs to a woman in child-birth. 
Much may in this case be attributed to heat. 

All local irritants, such as bHstcrs, mercurial inunc- 
tion, and plasters, favor confluence in parts to which 
they have been applied. Active purgatives, taken dur- 
ing the incubative stage, lessen the quantity of eruption 
by causing derivation of the fluids from the skin to the 
bowels. A plethoric state of body equally disposes to 
confluence, while it adds to the general severity of the 
disease, and is the main cause of cellular complication. 
Extreme weakness of frame delays the eruption, and 
dangerously represses that inflammatory process which 
is essential to the repair of the injury inflicted by the 
poison on the skin. 



HIASHATIO DRIQIir. 83 

Lastly : it may be remarked that (here exists in cer- 
tain individuals, and not unfreqiiently in members of 
the same family, a pocuhar irritabihty, under the inflii- 
eoce of the variolous conlagion, just as sonic persons 
sufTer severely from the smallest doses and the mildest 
preparations of mercury. The petechial form of smalt 
pox has for its cause this idiosyncrasy, or peculiarity of 
habit Such constitutions receive small pox with alarm, 
develope it with difticulty, and sink under its elimina- 
tion. On tlic oiber hand, oiher persons imbibe the 
morbid germ mildly, nourish it without siifTering, and 
eliiiiiuate it safely and kindly. 

The miasm of small pox belongs to every part of the 
body. It is given off both by the lungs and by tlie skin. 
The breath, the secretions, the matter of the pustules, 
the scabs, all contain it. It attaches itself to fomites, 
more especially the clothes of the patient, the bedding, 
and the bed furniture. These, if closely wrapped up, 
and secluded from the air. will retain the miasm, and 
^ve it out in an active state at great distances of time. 
But free exposure to the air greatly diminishes or alto- 
gelher destroys this infecting property; for the conta- 
gion, whatever be its inllmate nature, is very volatile. . 
The medical attendant, therefore, who goes into the 
open air after visiting a small-pox patient, is seldom 
found to communicate the disorder. Very absurd stories 
have been gravely told regarding the time during which 
fomites may retain their active powers. A physician at 
Plymouth describes a case of small pox originating in 
contagion brought from London in a periwig. Another 
doctor assures us that he knew a maid-servant who took 
small pox by washing tlie floor of a room two years 
after any small pox patient had been in it. 



84 EPIDEMIC DIFFUSION 

Experiments were made in 1832, by direction of the 
Royal College of Physicians of London, for the purpose 
of determining the power which a high temperature and 
chlorine gas are said to possess of destroying the activity 
of variolous contagion ; but the results were unsatisfac- 
tory. The sphere of contagious influence has been 
much questioned. Dr. Haygarth's opinion was that it 
was very limited, not extending more than a few feet 
from the patient's body. On the other hand, an Ameri- 
can physician, corresponding with Dr. Haygarth, affirms 
that the contagion, on one occasion, crossed a river 
1500 feet wide, and affected ten out of twelve carpen- 
ters at work on the other side ! It is undoubtedly very 
difficult to fix the distance at which the variolous poison 
ceases to be energetic ; but it is almost certain that the 
constitution of the air, in epidemic years, permits a very 
wide diffusion of the germ. 

Variolous matter may be diluted with water without 
its properties being in any degree altered. Dr. Adams 
first established this fact, which has since been corrobo- 
rated by the analogous experiments of M. Bousquet 
with regard to cow pox. 

We must now view small pox as an epidemic disor- 
der, as one that spreads in particular seasons, and in 
certain districts, without our being able to ascertain why 
that district, or season, is subject to such a visitation. 
The great epidemics of the last hundred years, in Lon- 
don, have been those of 1757, 1781, 1796, 1825, 1838, 
and 1844, the respective intervals between which have 
been 24 years, 15 years, 29 years, 13 years, and 6 years. 

Epidemic visitations, whether of small pox, or of any 
other alhed malady, acknowledge alike the law of rise, 
culmination, and decline. They advance gradually. 



attain ihoir crisis or height, and ihen gradually decline. 
Mr. Farr has, wirh his usual ingenuity, traccil the laws 
which appear to govern each of these stages of epidemic 
progress, and he arrives at the conclusion that epidemic 
decline is always less rapid than its advance. 

[It may Dot be uninleresting to slate more particularly the taw of the 
riw and decline of small pox to which our author alludes. Mr. Farr 
aya "it appears probable that the small pox increases at an accelerated 
and iheD at a retarded rate ; lliat it declines first at a bliglilly accele- 
mted, then at a rapidly accelerated, and lastly at a retiirded ral«, until the 
dj»ease attains the minimam intensity and remains stationary." The 
came law is said to apply also to measles, scarlet fever, and hooping 
cough, in London.] 

Sydenham remarked that when a small pox epidemic 
is mild, il begins about the vernal equinox (March 25) ; 
hot when of an extended and dangerous kind, it begins 
in the month of January, These observations are not 
confirmed by modem statistics. The last epidemic 
which the metropolis experienced began in November, 
1837, reached its acme in June, 1838 (being a period 
of eight months) — then slowly dechned, and ceased 
entirely in January, 1839, extending tlms through a 
period of fifteen months. The epidemic of 1796 fol- 
lowed a course very similar in all respects. 

Some epidemics are local, some are very extended. 
Small pox broke out in Norwich in 1319, and destroyed 
63U persons in that city between the months of May 
and October. It did not spread to other parts of the 
country. The epidemic small pox, the most remark- 
able for its extensive diffusion which perhaps ever 
occurred in the world, was that which began in Swe- 
den, in 1824, — reached England in 1825, spread to 
France in 1826-27, and ceased, in Italy, in 1828-29. 



86 EPIDEMIC DIFFUSION OF SMALL POX. 

The effects of this epidemic were very remarkable, and 
will be noticed hereafter, when the results of vaccina- 
tion are laid before you. Mr. Farr, in his second 
Report (1840), has given a very interesting table, show- 
ing the rise, culmination, and decline of the variolous 
epidemic of 1838, in each of the great districts of Eng- 
land. From this table it appears that the epidemic 
commenced in Liverpool in 1837, spread through the 
southwestern counties to the metropolis, diverged to 
Manchester and Leeds, raged in the eastern counties 
during the first half year of 1839, and then returned to 
its old haunts in Lancashire, after making a sweep 
around the island. From this fact alone we might 
learn, what innumerable other observations teach us, 
that the miasm of small pox is very indifferent to sea- 
sons, that the frosts of winter and the heats of summer 
are alike congenial to it. 

Small pox will sometimes spread in a cold and moist 
state of the air, sometimes wjien the atmosphere is clear, 
bright, or frosty. Nothing, in fact, has ever been 
observed, either with respect to the temperature, the 
moisture, the winds, or the general character of the 
atmosphere, which can throw light on the sources of 
epidemic visitation. It is worthy of remark, that the 
mortality by small pox always increases in years of 
epidemic prevalence. Small pox is then not only more 
abundant, but more severe than when it occurs as a 
sporadic malady. The difference in the rate of mor- 
tality may amount to ten or even twelve per cent. 

The susceptibility of small pox next claims our 
attention. All mankind, with few exceptions, are bom 
with a susceptibility of small pox. The European, the 



SUSCEPTIBIHTV TO BUALL POX. 87 

cegro, and the Hindoo, in tliis respect, at least, are on 
a par. This susceptibility, unless ahered by vaccina- 
tion, remains equally strong at all ages. Children, 
indeed, are the especial victims of small pox, but this ia 
merely because the disease is usually contracted on the 
first occasion of exposure to the miasm. There died 
in London of small pox during the two years 1840-41, 
223G persons, of whom 2060 were under, and only 226 
ahove 1.5 years of age. Nevertheless, to this law there 
are occasional exceptions. Persons have been known 
to go through hfe, e.vposed frequently to the contagion, 
yet never take it. Prior to tJie discovery of inocula- 
tion, and indeed after it, many thousands of mankind 
attained a good old age without ever experiencing an 
attack of small pox. Vet persons exhibiting this natural 
onsusceptibility, have nevertheless, late in life, received 
the disease by inoculaliou. A lady residing in Salis- 
bury was successfully inoculated for small pox in 1804, 
at the age of eighty-three, and lived several years after- 
wards. She had brought up a large family, many of 
whom she bad attended in an attack of small pox, but 
had never taken it herself A (cw persons pass through 
life apparently insensible to the variolous vims, whether 
casuallv or by inoculation; but such cases are rare. 
This very estimable privilege has been said to attach 
to particular families, hut there is no foundatioD for the 
notion. 

The great discovery of modern times is, that an 
onsusceptibility, or at least a deferred susceptibility of 
small pox, may be given to man artificially. We may 
80 alter and modify the state of his blood that he can- 
not take it. I need hardly tell you, that this expedient 
is vaccination. The security which it affords may be

permanent through life, or only temporary; but observe, 
— this is no more than happened to a few favored indi- 
viduals, by an inexplicable idiosyncrasy, before Jenner 
was born, or vaccination dreamed of. 

If there are people in the world who cannot be made 
to take small pox, this is more than compensated by 
those who have the bad luck to fall into it twice. 
Cases of secondary or recurrent small pox have been 
described in all ages, from 1{ hazes down to our own 
times. They were never very common — rar(z aves 
always — but they have occurred, and they may occur 
again. You must not, however, give credit to all that 
you hear said nowadays on the subject of secondary 
small pox. One gentleman, in reply to the queries of 
the Provincial Medical and Surgical Association, 
informed us, that in his own practice he had attended 
between eighty and ninety cases of recurring small 
pox ! He even goes further, and avers that he knows 
two families where small pox occurred a third time. 
Contrast with this the opinions of Dr. Mead, Dr. He- 
berden, Dr. Monro, De Haen, and other practical men 
of the last century, who hesitated very much about the 
possibility of genuine small pox recurring. Remember 
that De la Condamine, in 1754, estimated these cases 
at one in ten thousand ; others, at one in five thousand. 
At the Small Pox Hospital, very few persons ever pre- 
sent themselves who affirm that they have previously 
undergone small pox ; and of the few who do, but a 
very small fraction can stand the test of rigid scrutiny. 
In one of the last cases that occurred, a medical man 
who witnessed the first seizure had misgivings as to the 
true nature of the case. No instance is recorded of 
the same person having been admitted twice into the 



RErrilRRENCE OF SMALL PUX, 89 

Small pox Hospital. You may ask me why I am thus 
incredulyus on the subject of recurrent small pox 1 It 
is not that I have any theory to support, but it is 
because I know there are so many sources of fallacy. 
Sometimes the first case is incorrectly reported ; some- 
times the second. It is very rare that the same medi- 
cal maD sees and reports both the seizures. I have 
seen three cases of pustular syphilis so like small pox, 
that a careless observer, — nay, even a very careful 
observer, were he only to see the case once, might 
easily be deceived. But it is not only tiie pustular 
forms of syphilis which gives rise to mistakes. Lichen, 
and, above all, varicella, are fruitful sources of error. 
I was ouce called in to see a case of alleged secondary 
small pox, which, on investigation, proved to be 
ecthyma. I have evenseen psora mistaken forsmall pox! 
Id Dr. Baron's Life of leaner (vol. i. p. 278), it is 
remarked, " that when Jenner's discovery was first 
announced, it had escaped the attention of medical men 
that small pox occurred a second time so frequently, as 
it has since been proved to do, botli by recent experi- 
ence and past history." "Such an impression," adds Dr. 
Baron, " led to a too confident announcement of the 
never-failing eflicacy of vaccination," It is scarcely 
conceivable that Jenner, who for thirty years had been 
studying small pox closely, should have been so ill-in- 
formed on one of the most curious points of variolous 
pathology as is here alleged. It is difficult to believe 
that a principle of such importance shonld have escaped 
observation at a period when men's minds were so 
strongly drawn to the subject, and have attracted notice 
only when small pox was comparatively rare. The 
probability, therefore, is, that Jenner was correct in his 



90 CASE OP LOUIS XV. 

early views of the permanency of the protection which 
one attack of small pox afforded, and that the ardor of 
his followers in their support ( f vaccination led them 
to overrate the frequency of recurring or secondary 
small pox. 

With this impression strong upon my mind, I cannot 
go far into the history and peculiarities of recurrent 
small pox. I may, however, state to you, that some 
pathologists connect the phenomenon with a peculiar 
proneness in the system to suffer under the variolous 
virus. They argue thus, from observing that all well 
authenticated cases of second small pox have been of 
persons who in the first instance took it severely. 
Another class of pathologists explain the circumstance 
by supposing that the first attack had not been in suf- 
ficient intensity to absorb the whole amount of suscep- 
tibility. They argue thus, from having noticed that 
the fii-st attacks have been inild. This question I can- 
not undertake to decide, — tantas componere lites. 

The most remarkable case of recurrent small pox on 
record is that of Louis XV., king of France, who died 
of it in the year 1774, at the age of sixty-four, after 
having, as it is alleged, undergone that disease casually 
in 1724, when he was fourteen years of age. I have 
been at some pains to investigate this case, which cre- 
ated a great sensation at the time, has been quoted over 
and over again, and to which great importance has 
been attached. After careful inquiry into dates, the 
character of the incubative stage, and the course of the 
eruption, I convinced myself that his Majesty never 
had small pox in early life, and that the primary attack 
was varicella. 



COMMUNICATION TO THE P(ETUS. 91 

[For Temnrks on the occurrence of small pox a second time in tba

Appendix D.] 

Among ihe pectiliarities of small pox, the possibility 
of its occurriiig simultaneonslj with other exantheiiiatit 
must not be oDiittcd. Measles and small pox have 
appeared together, and run their respective normal 
courses, uninfliicneiug each other. At the Small Fox 
Hospital, I have seen many unequivocal cases of the 
concurrence of small po\ and scarlatina anginosa. 
Small pox and cow pox may co-exist, as I shall after- 
wards more fully explain. Sometimes each disorder 
runs its natural course. Occasionally one or other 
malady is modified either in aspect or progress. 

[For inslances of co-existence of small pox with other eianlhemala, 
see Appendix C, hefuro referred to.] 

There remains only one topic connected with the 
pathology of small pox, on which 1 would wish to 
address you ; and that is, the commuuicability of the 
disease to the fcetus in utero. Dr. Jcnner, Dr. George 
Pearson, ami others, have collected many curious facts 
on this subject, aud I am desirous to acquaint you with 
some of the most interesting of them. To do full jus- 
tice to the subject would lead me into a wide but 
unproiitable path. 

It does not necessarily happen that a pregnant woman 
taking small pox conveys the disease to the child. 
Several iustances to the contrary have occurred at the 
Small Pox Hospital. An opinion was entertained by 
Dr. Mead (but erroneously), that in cases where a 
woman undergoes small pox williout aborting, the infant 
would remain through life unsusceptible, having, in fact, 
passed through tlie disease iu utcro. Dr. Jenner has 



92 COMMUNICATION TO THE FCETUS. 

detailed two cases which prove very satisfactorily that 
a foetus in utero may contract small pox, provided the 
mother be exposed to the contagion, although she her- 
self does not take it. An infant born under these cir- 
cumstances sickened for the small pox five days after 
birth, and twelve from exposure to contagion. 

In a large proportion of cases, small pox communi- 
cated by the mother to the foetus destroys the infant's 
life. The child is often still-born. 

[For particulars of the cases reported by Dr. Jenner, referred to by 
our author, and a record of other cases and references on the subject, 
see Appendix K] 

In the neighboring museum of Guy's Hospital there 
formerly was, and perhaps is still, a foetus preserved, 
whose skin is covered with variolous pustules. Mr. 
Heaviside's museum contained a similar case. 

[A very well marked and well preserved specimen of the same kind 
is to be seen in the Museum of the College of Physicians and Surgeons, 
of this city.] 

The earliest period of foetal life at which I have ever 
seen traces of variolous eruption is four months. 

It is very seldom that a pregnant woman dies of 
small pox without aborting, or giving birth to the child. 
This seems to be a very general law of nature, applica- 
ble to all severe maladies, whether acute or chronic. A 
pregnant female, if consumptive, lives to give birth to 
her child, though she herself may sink, exhausted, within 
a few hours afterwards. It is apparently a provision of 
nature, giving to the offspring, under all circumstances, 
the best chance of life. The principle is illustrated in 
the history of scarlet fever, not less remarkably than in 
that of small pox.

TiJE power of medicine over small pox is not so striking 
as it is over inflaniinatiotts, over bowel complaints, over 
agues, or many other types of fever, IS evertheless, 
metliciue does exert a certain amount of influence over 
the course of this disease. Wliether it does so, bow- 
ever, or not; whether the amount of that influence be , 
great or small ; in either case llie management of small 
pox must be carefully investigated by yon — first, lest by 
your measures you may do mischief, and make bad 
worse ; secondly, because the world expects you to do 
something for the benefit of your patient, and vvliat that 
something is you must be taught, reuicmberlng always 
that improper treatment may do harm, though ibc very 
best may not do good. 

It is a melancholy reflection, but too true, that for 
many hundred years the efforts of physicians were 
rather exerted to ibwart nature, and to add to the ma- 
lignancy of the disease, than to aid her in her efforts. 
Blisters, heating ale.xipbarmics, large bleedings, opiates. 



ERRONEOUS NOTIONS OF SHALL POX. 



oiotments, masks, and lotions to prevent pitting, were 
idle great measures formerly pursued, not one of which 
■■can be recomuieuded. Wliat tliink yoa of a prince of 
' the royal blood of England (John, the son of £dward 
the Second) being treated for small pox, by being put 
into a bed surrounded with red hangings, covered with 
red blankets, and a red counterpane, gargling his throat 
with mulberry wine, and sucking the red juice of pome- 
granates T Yet this was the boasted prescription of 
f John of Gaddesden, who took no small credit to him- 
lelf for bringing his royal patient safely through the 
disease. We may smile at this ; but if either he, or 
Gordonius, or Gilhertus. were to rise from their graves I 
and inquire whether this is one wbit worse than Mes- 
merism, or at all more absurd than homoeopathy or 
hydropathy, we should, I fear, look a little foolish. Let 
ns, then, avoid the errors of our ancestors, without 
reproaching them. 

Even physicians, in more recent times, have enter- 
tained very erroneous notions regarding the powers of 
medicine in the treatment of small pox, and the objects 
which ought to be kept in view. They imagined that 
certain drugs possessed a power of promoting the erup- 
tion of small pox, and not only of promoting it, but of ' 
procuring a favorable sort. They arrogated to them- 
selves a like power of controlling secondary fever, and 
preventing its necessary consequence — pitting. We 
pretend to no such power. We know that the system 
has imbibed a morbid poison, which, somehow or other, 
must be got rid of; and consequently we study to place 
the system in the most favorable circumstances for the 
safe elimination (or concoction) of the morbid matter. 
We propose to ourselves, therefore, 



SOURCES OF DANGER. 95 

1. To moderate the violence of febrile excitement 
whenever we meet with it. 

2. To check and relieve local determinations of blood, 
at whatever period of the disease they arise. 

3. To support the powers of the system when it flags, 
either from the malignity of the poison or the long 
continuance of the disorder. 

4. To combat, by appropriate means, concouiltaut 
disease. 

You will bear in mind what I told you in a preceding 
lecture of the various sources of danger in small pox. 
As it is very important, in undertaking the management 
of the disease, to keep these in view, I will recall the 
principal circumstances to yonr minds. Danger in 
small pox depends — 1. on the quantity of eruption; 
2. on the condition of the mucous membranes; 3. on 
the state of the fluids; 4. on the slate of the brain and 
nervous system ; 5. on the age of the patient ; 6, on 
his habit of body ; 7. on the circumstances in which he 
is placed. 

1. Distinct small pox is a disease of littlp or no 
danger. Confluence is always unfavorable, especially 
on the face ; nor is the danger always apparent. A 
confluent case shall sometimes appear to progress favor- 
ably, when, unexpectedly, a fit of convulsion occurs, and 
the patient sinks. The drain upon the system which 
excessive pustulation occasions is another source of 
danger; nevertheless, if the pustules on the extremities 
acuminate well, and exhibit a crimson areola, a good 
ground of hope exists. If, on the other hand, the vesicles 
on the trunk and extremities be flat, with a clareiy 
areola, white the eruption on the face is white and pasty, 
no reasonable hope of recovery can be entertained. 



96 SOURCES OF DANGER. 

2. The condition of the mucous membrane of the 
trachea is equally important. Hoarseness at an early 
period of the disease is always to be looked upon with 
suspicion. A natural tone of voice is a good omen, 
even though the eruption be full and confluent, with a 
disposition to cellular complication. 

3. The condition of the fluids in small pox is a fea- 
ture of the utmost importance in guiding your judgment 
as to the probable result of the case. Everything which 
indicates putrescency and a dissolved state of the blood 
is highly unfavorable. Petechia;, mucous haemorrhages, 
menorrhagia, and vesicles filled with blood, preclude 
the hope of benefit even from the most judicious treat- 
ment. 

4. A tranquil state of the nervous system is peculiarly 
favorable, and the circumstance to which recovery in all 
severe confluent cases is mainly attributable, duiet 
nights, composure of manner, a contented disposition, 
and confident hope of recovery, are among the most 
pleasing signs that can occur, llestlessncss, a succes- 
sion of sleepless nights, constant moaning, and despond- 
ency, afford little prospect of eventual recovery. Chil- 
dren who grind their teeth seldom recover. 

5. Age is a point of great moment in estimating the 
degree of danger in confluent and semi-confluent cases. 
The extremes of life arc those on which small pox 
always falls the heaviest. Persons above forty years of 
age seldom recover even from the semi-confluent small 
pox. Children are in danger from an amount of erup- 
tion that can scarcely be called semi-confluent In 
both, the process of cicatrization is attended with great 
exhaustion of nervous power, the result of which is 
often the setting up of acute inflammation in an internal 



i 



aoDRCES OP OAHOBE. 

organ essential to life — either the brain, the larynx, or 
the lungs. The most favorable age for taking small 
pox is from the seventh to the fourteentli year, when 
the powers of Ufe and reproduction are in their fullest 
vigor. 

6. The habit of body is also to be taken into account. 
Small pox is always aggravated by its concurrence with 
a state of plethora. Conslhutional debility is equally 
to he dreaded. In the strumous habit, the sequels of 
small pox are peculiarly severe, and' often threaten the 
loss of life when the first dangers have been passed. 

7. The probability of recovery must depend, lastly, 
on the circumstances in which the patient is placed, — 
on the possibility of applying remedial measures effec- 
tively, on the treatment which may have been pursued 
tD the early stages, and other contingencies, which 
scarcely admit of enumeration. In hospitals, the risk 
of contracting erysipelas, and falling imder the influ- 
ence of hospital miasm, must never be lost sight of. 
In private life, again, the anxieties of friends may 
prompt a more stimulating regimen than prudence 
would dictate; and thus may local congestions and 
inBammations be excited, from which the hospital 
patient is exempt. 

With respect to the initiatory fever of small pox, it is 
cither known or not known that small pox is approach- 
ing. If it be not known, then the case is necessarily 
treated as one of common fever, to which ordinary mles 
apply. On the other hand, if it be known, or strongly 
suspected, that the variolous poison is circulating, then 
the question arises, should tliere he any corresponding 
difference of treatment ! Are you, on that account, to

refrain from bleeding, or to practise it ? — i 
gative. or to withhold it t It is always desirable 
ascertain. If possible, the fact of variolous origin, for the 
same reason that it Is better for a man to work in 
light than in the dark, hut the diSerences in treai 
are not material, as you will soon perceive. 

In the initiatory fever of small pox, tlie antiplilogist^ 
treatment is to be pursaed, except in a few special 
cases. The surface is to be kept moderately cool. A 
brisk cathartic, composed of four grains of the chloride 
of mercury, vrith eight of the compound extract of colo- 
cynth, may be given with great propriety, when there 
is considerable tumult of the general system. Saline 
draughts may be taken frequently in a state of efferves- 
cence, with the addition of a pill containing three grains 
of James's powder, lint if there be present pain of the 
back, or of the head, or of the epigastrium, more urgent 
than these measures can effectually control, blood may 
be taken from the arm. 

It has often been said, that blood-Ietling, in the fever 
of invasion, interrupts the process of nature, repels the 
eruption, or so retards it, and so weakens the constitn- 
tion, that the due concoction of the pustules is never 
effected. It is undeniable that a man may be bled 
unnecessarily and too largely in small pox, but a mode- 
rate bleeding does no hann, and, if the fever runs high, 
often does great good. If the pulse be sharp, or very 
full, if the headache be severe, with accompanying epi* 
staxis, blood-letting is not only useful, but absolutely 
indispensable; for the eruptive process is often impeded 
by the quantity of blood in the body, and the violence 
of the arterial excitement Huxham justly said, "that 
you should bleed in the onset of these fevers, for the 



EUFLOYHERT OP BLOOD-LBTTING. 

same reason that jou draw off part of a fenneiitmg 
liquor, — to prevent tiic splitting of tlie vessel. By 
drawing off some blood, you prevent the overdistending, 
inHaniiug, and rending tlie vessels of the human body." 

I can give yon no rules as to the quantity of blood to 
be drawn. Consider the circumstances of each case, 
and be guided by them. Your object is to unload and 
relieve the lungs, the hver, or the brain. Whenever, 
therefore, these organs are gorged, and their functions 
impeded by a load of stagnant or inflamed blood- 
when intense headache, extreme irritability of the sto- 
mach, oppressed breathing, with a full laboring pulse, 
give evidence of such general or local congestion, draw 
blood, and let the quaniity drawn be such as to relieve 
the urgent symptom. In some cases, when headache 
predominates, witli suffusion of the eyes, leeches applied 
to the temples, afford all the relief which is required to 
take off the strain from the vessels. It is under these 
circumstances that active purgative pills, followed by a 
laxative draught, are so useful in diverting the fluids 
from the head and surface to a mucous membrane 
which is never implicated in the ordinary march of the 
disorder. 

Some writers, in their zeal for blood-letting, have 
tried to persuade themselves that it is the only measure 
which can be relied on to lessen confluence, and to 
(ffeveot the development of pustules in the mucous 
membrane of the throat and trachea. This opinion 13 
altogether erroneous. Bleeding has no effect on the 
quaniity of eruption, whether cutaneous or mucous. 
The most confluent eruption has succeeded to the most 
vigorous employment of the lancet. To bleed, there- 
fore, merely because small pox is anticipated, with the

TKBATHENT DOBINCT THE 



Tiew, thereby, of prevcuiiug confluence, is uselessly to 
expend that power which will be required for the 
repair of injury to the surface. You will keep tliese 
general principles before you, and take care ihat iu 
your efforts to diminish internal congestion you do not 
materially impah constitutional power. 

If the stomach, durmg the initiatory fever, remains 
very irritable, rejecting everj-thing that is taken, even 
the sahne effervescing draughts with laudanum, which 
you will naturally feel disposed to try, I recommend 
you to apply mustard poultices to the epigastrium and 
to the feet, and to promote eruption hy the pediluvium. 

Again : if the circulation at this period be languid, 
if the pulse be small and feeble, the skin pale, and the 
extremities cold; if the patient lies on his back, sunk 
and exhausted, let liini have immediately warm brandy 
aiid water, cover him with bedclothes, apply mustard 
poultices to tlie centre and extremities of the circulat- 
ing system, and give thirty drops of laudanum, to be 
repeated in four hours, if necessary. This cordial 
plan of treatmeul must often be continued for several 
days, when the eruptive uisus is accompanied with 
depression, and nature appears so obviously unequal to 
the effort. 



While the pustules are in process of maturation, a 
variety of measures may be pursued, which, without 
interrupting the salutary and necessary process of ptis- 
tulation, lessen the patient's sufferings, and prevent sub- 
sequent difficulties. 

If the eruption proceeds favorably, you would not do 
more than lessen thirst by saline draughts, and occa- 
sionally reheve the bowels by a dose of castor oil. If 



HATURATITB 8TAOI.

the maturation of a large crop of pustules excites much 
fever, it will be prudeut to employ more active purga- 
tivps, such as calomel with colocynth, the compound 
powder of jalap, or the iafusion of scDua witli salts, all 
which cause a drain from the blood-vessels, and dimi- 
uish arterial action. Place the patient in a large and 
cool room, and cover him lightly with bedclothes. 
Remove all flannel coverings which may usually be 
worn next the skin. If the surface be very tender, 
apply to it some cooling lotion, such as the decoction 
of bran, wiili some spirit of rosemary. In all cases, 
even of moderate intensity, it is proper to cut the hair 
close, and so to maintain it during the whole course of 
the diseasa The head is thus kept cool ; delirium is 
relieved or prevented ; the risk of cellular inflammation 
of tlie scalp diminished, cleanliness enforced, and an 
opportunity afforded for the employment of evaporating 
lotions, should more urgent symptoms arise. Opiates 
may be occasionally administered at bed-lime, when 
there is much cuticular irritation, or great distress from 
want of sleep. 

The diet of the patient should consist of tea, bread 
ami milk, arrow-root, rice milk, and roasted apples. 
Grapes, oranges, and ripe subacid fruits, are grateful to 
the patient, and useful adjuvants to the antiphlogistic 
remedies. Lemonade, apple water, tamarind water, 
toast water, and milk and water, must be tbe ordinary 
beverages. ^Sydenham permitted his patients to drink 
small beer — an indulgence which may still be granted. 
To that able physician we are indebted for this, the 
cooling system of treatment in small pox. How 
strongly does it contrast with the plan of stopping up 
every nook and cranny, by which a breath of fresh air

could gain admission, and drenching the unbappj suf- 
ferer with treacle posset and symp of saffron ! 

One of the first objects which, in cases of more 
nrgcncy, will attract your attention, is the condition of 
the throat. Gargles of intusum rosie compos, afford 
some relief When the difficulty of swallowing is very 
great, and the tonsils much swollen, leeclies applied to 
the throat, followed by poppy water fomentations, are 
serviceable. Under these circumstances.some physicians 
counsel you to apply to the throat, by means of a camel 
hair pencil, a strong solution of lunar caustic (twelve 
grains to the ounce), with the view of checking the 
advance of the nmcous vesicles. 1 have not adopted 
this practice, from a conviction that it would not afi'ect 
the tracheal Inflamtnatiou, from which alone danger is 
to he apprehended.

have been attended with suceem., , 

Cldoniretted lotions are also highly recommended for the throat and 
nasal passages in severe cases of the confluent form.] 

Three measures Iiave been pursued, having for their 
object to diminish action on the surface of the body 
during tlie maturatlve stage. The 6rst was that of 
opening all the pustules, as fast as they ripen, by a gold 
needle. This was the Arabian practice ; but it is as 
useless as it is troublesome. The second is a modem

invention, that of appl)'iug lunar caustic to tlie pustules, 
so as to destroy theiu at an early period of their growth. 
As a partial appUcation — say, to vesicles forming near 
the eye, — I can recommend tliis measure; but I cannot 
advise you to employ it to any large surface covered 
witii continent or semi-conllnent vesicles. The pain 
which such au application occasions is very great, and 
must, of itself, add largely to the danger of the patient 
In the distinct form of small pox, the remedy would be 
worse than the disease. 

The latest mode of treating the surface during the 
maturative stage of small pox is that of applying mer- 
curial plasters, containing calomel or corrosive muriate 
of mercury, or covering the whole surface with mer- 
curial ointment. In the French hospitals at the present 
lime, the latter mode is iu fashion. Tiie reports which 
have reached me of its success, however, are not very 
flattering. I have seen all tliree plans fairly tried at 
the Small Fox Hospital. The ointment and calomel 
plasters were inefficient. The plaster of corrosive 
sublimate converted a mass of confluent vesicles into 
one painful and extensive blister, but I am still to learn 
what benefit the patient derived from the change. 

Throughout tlie whole period of maturation, you will 
look carefully to the state of the internal organs. In a 
very large proportion of cases these are unaffected, but 
bronchial in 3 animation, and even poeunionia, maj 
aapervene, which you will meet by the usual remedies. 
lo cases of delirium, carefully restrain the patient, 
exhibit active purgatives, and wait until the full matura- 
tion of the pustules shall have relieved the tension within 
the head.

The decline of the mild form of small pox requires 
little else than attention to the state of die bowels, and 
care lest too great indulgence of the appetite should 
light up feverish excitement. A warm bath is always 
advisable before the patient ml-ves again in society. 
Vapor baths, when they can be procured, arc very 
vicealile in promoting a more healthy state of 
surface. 

The dlfRcuhies id the management of small pox 
begin with the setting in of secondary fever. Tlie com- 
plications are then so numerous, the struggle betwei

tlie disease aud the constitution so close, excitement 
and exhaustiou tread so near upon each otiier, lliat it is 
scarcely possible to assist you witli any mies admitting 
of precise applicatioa. I shall satisfy myself, therefore, 
with some remarks on the chief points which will 
attract your notice, first treating of internal, and then of 
external remedies. 

One of the most remarkable dispntes which ever 
arose in physic was that regarding tlie propriety of 
using purgatives during the secondary fever of small 
pox. Sydeudani, with all his boldness, never wholly 
divested himself of the early prejudices which tlie Ara- 
bians had inculcated against purgatives in small pox. 
Morton inveighed bitterly against their use, while Dr. 
Friend, with the trne spirit of a reformer, advocated 
their free employment, especially during the secondary 
fever. 

In 1708 a young nobleman took confluent small pox. 
Dr. Friend was called in wirh two physicians of the old 
school. The arguments in the consulting room were 
long and stormy. The patient died, in spite of the 
purgatives which Dr. Friend's pertinacity had at length 
induced his colleagues to agree to. A paper war suc- 
ceeded, and from words the parties came to blows. Id 
June, 1719, Dr. Mead and Dr. Woodward met io 
Cheapsidc, drew their swords, and, after a few passes, 
Mead came off victorious. This display effectually 
settled the dispute, and purgatives are now as fi'eeiy 
employed in the secondary fever of small pox as in 
ague or in typhus. They are of the greatest service 
when the skin is hot and dry, when scarlatinal rash 
covers the body, or innumerable abscesses give evidence 
of the excited state of the cutaneous vessels. 



106 TKEATMBIfT III SECO!fDAKT FEVER. 

pTofase postnladon demaDds tliat the strengtb of the 
systcoi should be supported by uourishing diet, an allow- 
ance of ale, porter, or wine, and cardial medicines. In 
the great depression which sometimes succeeds the 
destraction of large portions of the surface, wheu sub- 
sdHus tcndiaam, geueral tremors, a feeble pulse, and a 
dry tongue, attract observation, wine mnst be liberallj 
adniiiiislered. with beef-tea, and a mixture containing 
citric sther and the carbonate of ammonia in camphor 
jolqt. 

In the progress of secondary fever we sometimes 
witness the access of rery acute seizures, such as phre- 
nitis, apoplexy, pcripneumony, and pleurisy. Blood 
may be taken freely from the arm in many of these 
cases. In others, leeches aiTord the only palliative 
which medicine can suggest. Blisters are, from the 
condition of the surface, seldom, il' ever, applicable. 
Syncope, palpitation, coM extremities, and other evi- 
dences of deficient power, and cardiac implication, 
demand the administration of wine and ether. 

Erysipelas, succeeding small pox, must be treated with 
reference to the accompanying state of the circulation. 
For the most part, it is best combated by purgatives 
and saline medicines. Sometimes, wine and die decoc- 
tion of iiarl( are indicated. Ophthalmia is one of the 
most serious evils which the secondary fever of small 
pox gives rise to. The loss of blood, which the inten- 
sity of the symptoms appears to warrant, would be 
followed by great and perhaps irremediable esbaustioiL 
In some caseH, therefore, the eye must be sacrificed to 
save the patient's life. Leeches, cupping-glasses to the 
temples, active aperients, calomel, pushed so as to affect 
the mouth, with warm fumentations, are the remedies

OD which you must mainly rely. In a more chronic 
form ol' the complaint, blisters to the temples a0brd very 
decided benefit. 

When small pox has called into activity the dormant 
seeds of scrofula, when irritable sores, irritable ophthal- 
mia, enlarged joints, and ecthymatous pustutation, com- 
hiiie to weaken an already debilitated frame, your 
utmost efforts will be called into requisition, but often 
with doubtful success. The best remedies are occa- 
sional warm baths, a course of sarsaparilla, and mode- 
rate doses of blue pill and rhubarb, to insure due action 
of the liver. The remedy of most uuqnestionahle 
efficacy is change of air. It imparts tone to the lan- 
guid vessels of the surface, converts an ecthymatous 
Burface into healthy granulations, improves the appe- 
tite, and gives tone to the retina. The influence of an 
altered air on the diseased actions of the body is better 
displayed in the sequel® of small pox than m any other 
known disorder. 

A few words on external treatment will conclude this 
division of the subject. When pustulation is profuse, 
benetit is obtained by covering the surface liberally with 
some simple dry powder. Starch powder, hair powder 
(well dried), and the powder of calamine, arc alike 
available for this purjHJse. Cold cream, and mild 
unguents, such as the ung. cetacei, with a proportion of 
oxide of bismuth, are useful when tliere is much cuta- 
neous irritation wilh a dry surface. Fomenlalions and 
poultices are the only local means of treating those 
abscesses and erythematous Inflammalions which so 
harass the patient and so fearfully peril life in the later 
periods of secondary fever. 

All the attempts made by the use of masks to prevent

pitting, cud in disappointnieoL The only effcctnal 
means of lessening such disfigurement are those which 
allay cutaneous action. Purgative medicines, low diet, 
and free exposure of the face to a cool air, are the sole 
measures on which your reliance ought to be placed. 

[Other means besiiioa tliose menlioned in the text have been used for 
preventing pitting, either by causing the abortion of the pustules in their 
fbrmieg stage, or drying them up after maturation, and upon authority 
which would seem to render them worthy of notice. 

For the different applications wbicb liavc been recommended, i 
manner of using them, their modus operandi, &c., see Appendix F.] 

Inoculation having been abolished by act of parlia- 
meut in this country, any lengthened details concerning 
it would of course be superfluous, and very much out of 
place. Nevertheless, a measnre so remarkable in its 
consequences, and which, for the better part of a cen- 
tary, was the object of general attention, to which 
every individual in this kingdom above the age of 
forty-two now trusts as his security from a loathsome 
pestilence, must not be passed over without a short 
comment. 

Inoculation is performed by introducing into the arna, 
at the insertion of the deltoid, by means of a lancet, a 
minute portion of variolous matter. The thin lymph 
of a fifth-day vesicle is to be preferred to the well-con- 
cocted purulent matter of the eighth day, but both are 
efficient. One incision only is to be made. A minute 
orange-colored spot is perceptible, by aid of the micro- 
scope, on the second day ; on the third or fonnh day a 
sensation of pricking is experienced in the part. The 
punctured poiut is hard, and a minute vesicle, whose 
centre is depressed, may be observed, surmounting an 
inflamed base. On the fifth day, the vesicle is well

developed, and the areola commences. On (he sLvth 
day, tlie padcDt feels stiffness in the axilla, with pain. 
The inoculated part has become a bard and inHamed 
phlegmon. The sutijacent cellular membrane has 
become involved in the Inflammatory' action. On the 
evening of the seventh, or early on the eighth day, 
rigors, headache, a fit of syncope, vomhing, an offensive 
state of the breath, alternate heats and chills, languor, 
lassitude, or, in the child, an epileptic paroxysm, 
announce the setting in of fever. The constitution 
has taken alarm, and sympathizes with the progress of 
the local disorder. 

On the appearance of febrile symptoms, the inflam- 
mation of the anil spreads rapidly. An areola of 
irregular shape is soon completed, which displays within 
it minute confluent vesicles. On the tenth day, the 
arm is hard, tense, shining, and very red. The pustule 
discbarges copiously, and ulceration has evidently pene- 
trated the whole depth of the corion. 

On the eighth day, spots of variolous eruption show 
themselves in various, and often in the most distant, 
parts of the body. In a very large proportion of cases, 
the eruption is distinct aud moderate. Two hundred 
vesicles are counted a full crop. Sometimes not more 
than two or three papula: can be discovered, which 
perhaps shrivel and dry up without going through the 
regular process of maturation. At other times, the 
eruption is full and scnii-confluent, passing through all 
the stages of maturation, and scabbing, and cicatriza- 
tion, with as much perfection as the casual disease can 
display. Between tliese extremes every possible variety 
may be observed. The truly confluent erupliou with 
affection of the mucous membranes is very rare, and

t)iat liiiplicatioD of the fluids and of the uervous system, 
which together constitute the extreme of variolous 
maliguit)', is nearly, if not entirely unknowD. Secon- 
dary fever, therefore, is not cominou, at least in any 
intensity. 

The rules laid down for the safe conduct of inocula- 
tion were priucipally the following; — It should be per- 
formed exclusively in persons free from actual hodily 
disease, and neither plethoric uor scrofulous. It may 
be safely practised at all ages, heginning at the third 
month. It is improper to inoculate during pregnancy, 
on account of the dauger to tlie child in utcro. It may 
be practised iu all seasons and in all climates. It 
proved not less successful among the negroes in Jamaica, 
than in the inhabitants of St. Petersburgh, Perfect 
health being the best coudition for receiving and safely 
eliminating the poison, everything that tends to dimi- 
nish plethora, to lessen cutaneous action, to render the 
bowels free, to preserve the blood in a cool, pure, and 
uoniial condition, was found useful. Laxative medi- 
cine, a moderate diet, alistinence from all fermented and 
spirhuous liquors, cool chambers, gentle exercise in the 
open air, light clothing, — all contributed, in their several 
degrees, to the successful result. The autimonial aod 
mercurial medicines, which the Suttons laid much stress 
upon, were useful only to secure the co-opcrutioD of 
the patient in matters of more necessity, especially diet 
and exposure to the open air. 

You will naturally wish to know what was the prac- 
tical result of inoculation. 1 will tell you in a few 
words. Its influence in lessening the mortality of small 
pox was something quite extraordinary, and scarcely 
credible. With ordinary precautious in the choice and

preparation of subjects, not inore tban one in five hun- 
dred cases will terminate unfavorably. Tlie ill success 
which attended the early inoculations, between the 
years 1722 and 1730, arose entirely from bad manage- 
ment, from the most culpable negligence in the choice 
of subjects, and an utter ignorance of all the principles 
by which the practice of inoculation should be governed. 
Had not the discovery of Jenner interfered to interrupt 
its extension and improvement, inoculation would have 
continued to this day increasing yearly in popularity. 
It cannot be doubted that improvements in medical 
science generally would have shed additional lustre on 
this practice. 

Since the introduction of vaccination, it has been the 
fkshiou to decry inoculation, and to impute to it mis- 
chief of which il was not guilty. The great objection 
made to inoculation, and that which recently induced 
Parliament to abolish it ahogothcr, under lieavy penal- 
ties, was, that it disseminated the virus, and multipUed 
the foci of contagion. Dr. Watkinson and Dr, 
Schwenke, in 1777, and more recently. Dr. Adams, 
broke the force of this argument, by pointing out how 
important a part epidemic influence plays in the diffu- 
sion of variola. Had they lived in our times, how 
strongly would they have fortified iheir arguments ! 
We saw, in 1838, an epidemic small pox raging Id 
London, where inoculation had long been discontinued. 
The admissions into ihe 8mail Pox Hospital in that 
year exceeded those of 1781 and of 17£)G. Inoculation 
was abolished throughout England and Wales in 1840, 
and the act has been most rigidly enforced; yet, during 
the two last years, small pox has visited every county 
of England. 




RESULTS OP INOCULATION. 






Sir Gilbert Blanc has attempted to prove bys 
ihe evils of iDoculatlon. lie has shown that the pro- 
portion which the mortality by small pox in London 
bore to the general mortality, increased during the last 
century from 78 to 94 per thousand, but many circum- 
stances must receive attention before we are Justified in 
drawing conclusions from this fact. The population 
increased prodigiously in the interval, more indeed than 
would suffice to explain the increased iiiortahty by small 
pox. But, further, the general mortaUty diminished. 
CoDsetiuently, tliough the actual mortality by small pox 
had remained stationary and uninfluenced by popula- 
tion, its ratio to the total mortality would appear to 
augment. Thirdly, Dr. Adams has shown that a cor- 
respondent increase took place in scarlet fever alid 
hooping cough, whicli are not communicable by inocu- 
lation. Lastly, a different mode of calculation would 
exhibit a very different result. The sophism consists 
in arranging your figures so as to include or exclude 
years of epidemic prevalence. If, for instance, we 
divide tlic last ninety years of the 18lh century into 
three periods, we shall find that the recorded deaths hy 
small pox were as follows : — 1711 to 1740 (when there 
was no inoculation), 65,383; 1741 to 1770 (when 
inoculation was coming ioto general use), 63,308 ; 1771 
to 1800 (when inoculation was almost universal), the 
deaths were only .57,268 : so that, by this showing, 
inoculation diminished the mortality by 8115 lives! 

Statistics are very useful, and deservedly carry great 
weight witb them; but they may be enlisted, with a 
little management, on both sides of an argument. 

[For remarks on tJie influence of inoculation upon mortality, seo 
Appendix G.] 



ABOLITION OF INOCULATION. llo 

One subject only remains for our consideration, and 
that is. the question wiiether any circumstances would 
still warrant us in recommeudiiig inoculation on scien- 
tific principles ? Concurring most cordially in opinion 
that the practice of inoculation by unqualified persons 
ought to have been put down (uot in 1840, but forty 
years before that) by stringent legislative enactments, I 
still remain of opinion, that under several circumstances 
it is the duty of a medical man to recommend inocula- 
tion. These circumstances do not, indeed, often occur; 
hut the legislature would hardly wish to control and 
fetter, even in a single case, the deliberate judgment of 
a physician, acting for the benefit of his patient. I will 
name to you four of these cases; — 1. When a person 
has been found, from peculiarity of habit, unsusceptible 
of vaccination. 2, When new sources of vaccine 
lymph are introduced, and it becomes of importance to 
ascertain that the new virus is efficient. 3. When 
young persons (between the ages of ten and twenty), 
vaccinated in early life, are proceeding as cadets to 
India. 4. When small pox unexpectedly breaks out in 
a country district, at a lime when (even with the 
facilities of a penny post) vaccine virus is not to be 
obtained. 

Other cases, equally strong, might be put ; but what 
I have said will probably sufiice to show that a clause 
(duly guarded against abuse) permitting qualified medi- 
cal practitioners to inoculate under circumstances of 
urgency, would have been an useful addition to the 
Vaccination Extension Bill. That it was not so added 
was DO fault of mine.

Rubeola,. or measles, the roiigeole of the French, the 
morbilli of Sydenham and other old authors, is an exan- 
thematous disease, characterized by the following 
symptoms : — A fever, with catarrhal implication, which, 
at the end of seventy-two hours, throws out an abundant 
eruption, consisting of minute confluent papulae, sUghtly 
elevated above the surface of the skin, and subsiding in 
three, or at furthest, in four days ; the catarrhal symp- 
toms, in all normal cases, declining on the appearance 
of eruption, but sometimes, especially in severe and 
irregular cases, continuing, or merging in those of pneu- 
monia. The disorder, for the most part, occurs to all 
mankind once in the course of life ; but having been 
undergone, the constitution remains for ever after 
unsusceptible of the same disease. 

No complaint j)ossessing these very striking features 
is to be found recorded in the writings of any Greek or 
Roman author. Dr. Willan (in his Miscellaneous 
Works, 1821) struggles hard to prove that such a dis-

case was known to iliem ; hut his researches have 
made no converts. The opinions of Friend and Mead 
are still adopted, and we are constrained to believe that 
the measles is a disease of comparatively modern origin. 

All our best medical historians concur in the behef 
that measles began to spread flirongh the world about 
the same time as small pox. and that it had its origin In 
the same countries whence the variolous miasm arose. 
The shores of the Red Sea, the coasts of Arabia and 
Abyssinia, first experienced the assaults of this malady, 
and probably abont the fifth or sixth century. Constan- 
dne Africaous dates the origin of measles two or three 
centuries after small pox; but I know not on what 
grounds. The first distinct allusion to measles is found 
in the writings of Rhazes, the Arabian physician already 
mentioned as the fl«c^or^^Wnc^^,t on small pox. Khazes 
is supposed to have flourished early in the tenth century 
(910). His successors. Hall Abbas and Avicenna, the 
two most distinguished authors of the Arabian school, 
described measles under its Arabic name, Hasba, or Al 
hasbet. The term j-uheola was introduced subsequently 
by the Latin translators of Hali Abbas, and by some 
appears to have been appropriated to that variety of 
exauthema now called scarlatina. 

The term morbilli was employed from a very distant 
period also, and seems to have included every variety of 
exanthema, accompanied by efflorescence, lu this sense 
morbilli was used by Morton at the close of the seven- 
teenth century. Sydenham carefully restricted the term 
morbilli to measles. 

It is not only curious but instrucllve to trace the 
gradual expansion of men's minds in the diagnosis of 
the exanthemata. All the Arabian authors were im- 



116 IDENTITY OF MEASLES AND SCARLATINA. 

pressed with the belief that small pox and measles 
were pathologically associated. Avicenna pronounced 
measles to be a bilious small pox. In 1640, Daniel 
Sennertus proposed as a subject of inquiry, why the 
disease in some constitutions assumed the form of small 
pox, and in others, that of measles. 

Diemerbroeck, in a posthumous work, published in 
1687, asserts that the two diseases are only different 
degrees of the same malady. " Differunt morbilli a 
variolis accidentaliter, vel quoad majus et minus." 
" The matter by which measles is generated," says he, 
" is not so thick as in the case of small pox. It is 
drier, and somewhat choleric." (Choler, or bile, was 
the dry humor) This author held that such as had 
had small pox were generally exempt from the measles, 
" though, 'tis true they can challenge no absolute immu- 
nity. Therefore," he adds, " measles is chiefly met with 
in young persons." 

Sydenham, who was the contemporary of Diemer- 
broeck, and a much bettor physician, devoted much of 
bis attention to measles. He described with great 
accuracy the epidemics of 1670-74, and his opinions 
concerning measles display singular acuteness. He 
permanently separated small pox from measles, which 
was a great step in pathology. The belief in the 
identity of measles and scarlatina, however, still pre- 
vailed. Twenty years after the time of Sydenham, 
Morton viewed measles and scarlatina as the product of 
the same miasm, and averred that they stood to each 
other in the same relation as the distinct and confluent 
small pox. Hence, by many authors of that age scarla- 
tina was called morbilli confluentes. Even so recently 
as 1779, Dr. Withering speaks of measles as being 



IMCUBATIVE STAGE. 

nearly allied to scarlatina. By this time, however, 
physicians had become sensible that the two diseases 
arose from different miasms. This conviction was 
forced upon them hy observing that patients who had 
gone through measles were equally with others subject 
to scarlatina. 

Having brought down the history of measles to our 
own time, 1 proceed to describe to you its phenomena. 
I shall first make you acquainted wiih measles as it 
occurs in healthy habits, and in its simplest and most 
asnal form. This constitutes the morhilli regulares of 
Sydenham. 

Measles is the product of a miasm or morbid poison, 
which in this country is invariably received by the mode 
of infection. It has, of course, its breeding or incubative 
period. The term latent period is improper, because 
ihe miasm, often from the very first, gives evidence of 
its activity. Sometimes the entire incubative stage is 
marked by languor, lassitude, a sense of mal-aise (or 
dis-ease), and occasionally a characteristic cytiiptom, 
such as cough. I once attended a lady, wlio for a fort- 
night had a cough which baffled us all, but terminated 
at length by a copious eruption of measles. At other 
times, the first eight or ten days of incubation are passed 
without any sign of ill health. 

The early authors, biassed, no doubt.'by their preju- 
dices in favor of exanthematic identity, taught that the 
initiatory sympioms of measles were the same as those 
of small pox. This, as a general rule, cannot be admit- 
ted. With regard to the duration of such symptoms, 
authors are more agreed. Heberden says that from ten 
to fourteen. Burns that from twelve to fourteen days. 



118 CHARACTER OF THE 

usually elapse from exposure to contagion to the appear- 
ance of rash. Dr. Willan considers sixteen days as the 
extreme limit. The first week being usually passed 
without symptoms, the child (for the greater proportion 
of your measly patients will he children under seven 
years of age) then droops. Catarrhal symptoms super- 
vene. Chills, flushes, disturbed nights, some degree of 
delirium or drowsiness during the day, with weight on 
the forehead, are then observable. Pain of the back is 
a frequent symptom. The pulse is quick. The tongue 
is white. 

From the occurrence of rigors to the appearance of 
rash, seventy-two hours elapse. The initiatory fever of 
measles aflfects the quartan type. Two complete days 
intervene. The rash comes out on the fourth day from 
the setting in of fever, and the eleventh or twelfth from 
the imbibition of the poison. The following cases will 
illustrate the ordinary process of incubation, and the 
anomalies occasionally witnessed : — 

Case 1. — Miss M. D., aged seven years, residing in a 
retired situation at Woodgrecn, was brought to London 
on Tuesday, January 10, 1843, to attend a juvenile 
party. One of the children whom she there met, sick- 
ened for the measles on the following day, and before 
the end of the week tw^o others of the party had been 
seized. On the morning of Tuesday, January 24, 
being fourtcert days from exposure. Miss M. D. began 
to complain of languor, headache, sneezing, and cough. 
The eyes were suff'used. On Friday, the 27th, measles 
appeared on the face. The full incubation extended 
here to (;igliteen days. This young lady was attended 
by Dr. Munk, of Finsbury-placc. 

Case 2.— On Tuesday, February 14, 1831, Mrs. D.,

aged '26, went to Cainberwell in a hackney coach. The 
coarbmaa appeared ill as he let down the steps. At 
dinner, Mrs, D, fell sick and poorly, and so continued 
al! the rest of the week. On Tuesday, February 21 
(eighth day), she complained of rigor and violent pain 
of the back. Her husband, a surgeon, imagined she 
was passing a calculus. This pain continued all 
Wednesday and Thursday, On Thursday, the 23d 
(tenth day from exposure), I first saw her. The symp- 
toms were backache and headache. The eyes were 
suffused ; the pulse 130. On Friday, the 24th, at ten 
A,M., seventy-two hours exactly from the first rigor, 
measles appeared. Eleven days of incubation. 

Case 3. — Eliza Finch, aged four months, residing al 
Pentonville, was vaccinated by me at the Small Pox 
Hospital, May 15, 1832. May 17, the child began to 
droop. Bilious vomiting, very severe, with drowsiness, 
succeeded. Much blood passed by stooL The head 
was very hot. Vomiting continued all that and the 
four following days. It ceased on the 22d, On the 
24th the other febrile symptoms yielded a little. On 
the 25th (nine days from the invasion of symptoms, and 
eleven from the probable reception of the germ), measles 
appeared, and went through its course regularly.

of more recent infection from fumites or fresh exposure than instances of 
prolonged incubation.] 

The leading features of tlie initiatory fever of measles 
are, I have said, catarrhal. I must describe them to 
you more in detail. 

1. There is sneezing. I have seen both adults and 
children sneezing every five minutes, and really ex- 
hausted by it. In the case of Robert Woodland, whom 
I attended in June, 1830, the sneezing ended in epi- 
staxis. You know that sneezing indicates a gorged and 
irritable state of the Schneiderian membrane. 

2. l*he eyes are red and watery. There is epiphora^ 
the great diagnostic on which nurses are wont to rely. 
While the measles are breeding, you will be sure to find 
the window-blinds down, and the curtains of the bed 
close drawn. The slightest ray of light is painful. 
There is irritability of the retina, sometimes attended 
by inflammation of the conjunctival membrane. 

3. There is a loud, dry, hollow cough {tussis sicca). 
The violence of this cough, on some occasions, will 
astonish you, as it did me many years ago, while attend- 
ing a young Irishman, Mr. Webb, at Islington. It was 
not only loud, but incessant. The trachea and bronchi 
participate in the same kind of action (whatever be its 
nature) which takes place in the nose and eyes. 

4. There is hoarseness {raucedo). The larynx is 
also implicated. In fact, the mucous stnictures gene- 
rally of the head and chest receive the first impetus of 
the poison. We are not justified in saying that the 
action developed in them is inflammation. The mem- 
branes arc probably only in a state of congestion with 
increased irritability — a state which plethora, bad

mauagement, a cold season, or a bad habit of body, 
may convert into inflammatiou. 

Ever since measles was separated from scarlatina, 
authors have described au exantheniatic disorder, allied 
in aspect to rubeola, but not exhibiting any initiatory 
catarrhal symptoms. Such a complaint has been called 
rubeola sine catarrho, or incocta. By some it is called 
the bastard, spurious, or imperfect measles. Much 
attention has been paid to it in Germany. Dr. Willan's 
opinions on it seem to guide the pathologists of this 
country. He considered it as a species of measles, 
arising from the true rubeolous poison ; but he added, 
"persons receiving the miasm in this form are pecu- 
harly liable to a second attack of measles." 

This last admission seems to me nearly decisive of 
the (juestioiL 1 beheve that by farlhc larger proportion 
of such cases are cases of febrile lichen. I should he 
inclined to lay all the stress on the duration of the ini- 
tiatory feve-. If this extends to 72 hours, the disorder 
is measles, whether catarrhal symptoms be present or 
not. On the other haod, if a rash of a rubeolous charac- 
ter succeeds a brief period of febrile commotion (24 or 
48 hours), the disease is not measles, and tlie child will 
fall into true measles at some subsequent period of its 
life. It is worthy of note, that no author who has 
treated of this bastard or imperfect measles mentions it 
as occurring after the true measles. 



[The casos whicli v?6 have much more frequeiiUjf seen oonfuunde<] 
with in«i»les, axul irLich probably ounstitute the largest share of " rube- 
oU sine catarrho," have been those of Koscola, between the cutiiiieona 
developments of which and of Rubeola there is often great reaeiiiblanoe. 

The question is often asked, whether measles can exist wilhoul the 
eruplioa.

MATURATION OF UEA8LES. 123 

Pltoi]i,'lil perhaps lo be nieutii.ned in ibis counexiou, tbaUa iiinUar 
rednes'* in these ptirts somutinies occurs in RoseoU,] 

When closely examined, the eruption is found to con- 
sist of a congeries of minute papula, close set, or con- 
Buent, and for a short time perceptibly elevated above 
the level of the snrronnding skin. This elevation, or 
roughness, is most perceptible on the forehead. On 
the Umbs it is scarcely to be delected. The color of 
the measly ernption is a diugj' red, very different from 
the bright scarlet hue of its rival. Hence the French 
name llougeole, or fievre rouge. The difference in 
color may easily be traced to the tracheal and bronchia! 
complicalion so generally present in measles, which, 
extending partially into the substance of the lungs, 
gives a venous character to tlie blood. In .scarlet fever, 
on the other hand, the lungs are unaffected, while there 
is intense arterial action. The eruption, therefore, par- 
takes strongly of tlie character of arterial blood. 

The development of eruption is often accompanied 
with a very moist state of the surface. This is the 
Dornial mode of development, and of course always to 
be desired. Few, if any cases, that begin thus, end 
unfavorably. The same thing is true of all exanthema- 
tic disorders. In a hot and dry state of the surface, 
eruption is difficult, partial, and imperfect. 

By Willan and others, the patches of measly eruption 
are said to assume a crescentic arrangement. I have 
often been disappointed in my search for this appear- 
ance, and am inclined to think there is some little fancy 
called inti play in this description. 

On tiie second day of eruption (the fifth from the 
occurrence of rigors), the eyelids often swell, from the 
extension of cutaneous action to the subjacent cellular

tissue, . Although I have never seen such a thing, I 
have yet heard of children blinded bj measles during, 
the space of four days. The progress of measly era] 
tion, in all normal cases, is steadily from above dowi 
wards. On the second day of eruplion, the trunk and 
upper extremities are occupied. On the third, it has 
extended to the lower extremities, by which time it has 
nearly disappeared from the face. On the sixth day, id 
has faded over ihe whole surface. 'fl 

[Bnnliez ii Rilliet say tliat there is a period of incn^asa id nieaa^H 
whieli lulls one or two days, and n period of decrease which lasts thf^^| 
to fiftci^n dajs, the eruptiou being staUonaty but a very short tid^H 
(Mai. do eri/anU). The eruplion has most ooRimonly disappeared at d^| 
end of sin dnvB ; but not unfre'juonUv reoiHiaa until the serenib, M^H 
sometimes even liii^n to tbe DiDth or teolli duy.] ^| 

Some modiiications occur even in the most regal^f 
measles. One of the most familiar is an abundant crojfl 
of miliary vesicles on the arms and trunk, filled with a^ 
thin transparent lymph, and of such size and distinct- 
ness as to create a suspicion of the disease being small 
pox. We may well believe that tlie frequency of this 
event led originally to the idea of identity. Measles of 
this kind has been called rubeola variolodes, or the 
nirles. Pathologists have reasoned themselves into the 
belief that this symptom is owing to a peculiarly inflam- 
matory state of the cutaneous capillaries, but it will 
be observed in mild cases, unaccompanied with high 
fever. 

Another anomaly merits notice, the reappearance or 
exacerbation of the rash after having reached or passed 
its regular crisis. Dr. Willan first noticed this circum- 
stance. He records two cases of the kind in his ■• Re- 
ports of the Diseases of London.'' Frank, of Vienna,

DECLINE OF MEASLES. 125 

has observed the sauie thing. Dr. Conolly recites a 
like case, where the renewed eriiptiou was so copious 
and itiTeose on the face as to make it impossible to 
recognise the features. Some years ago, a case in 
every respect similar occurred at Brompton to Dr. Sey- 
mour and Mr. Chinnock. Ten days elapsed in this 
instance before the reuewal of the exanthematic action. 

By most authors, it is staled that the decline of 
measles ts attended with desquamation of the ciiticio, 
the scales being so minute that the body appears as if 
sprinkled over with fine bran. That this is perceived 
in some cases is Duquestionabte, but in many no such 
destruction of cuticle takes place. The cause of 
desquamation Is the intense heat of skin which dries up 
and kills the minute fibrils connecting the cuticle with 
the corioD. Desquamation does not form that striking 
feature of measles which it does of scarlatina and erysi- 
pelas, because tlie heat of surface seldom attains the 
requisite degree of intensity. 

In the perfectly regular measles, the cough, hoarse- 
ness, and other mucous symptoms, begin to abate on the 
first appearance of eruption. I have seen the cough cease 
instantly, as if by magic. Let me pause for a moment 
to illustrate, by this means, the mode in which blisters 
relieve a teasing winter cough. The principle is exactly 
the same. The skin and tracheal membrane arc analo- 
gous or homophysic structures, and irritation set up in 
the one, whether by nature or by art, relieves irritation 
(and even inflammation) in the other. 

The sequela;, or dregs, of measles require from you 
as much study as the earlier periods of the complaint. 
I have described the normal progress of measles in per- 
fectly healthy subjects. 1 am now to trace its effects 



126 RUBEOLOUS PNEUMONIA. 

■ 

on weakened and scrofulous constitutions. Generally, 
in such habits something occurs early to give cause of 
uneasiness. The initiatory fever has been severe. The 
eruption has been retarded twelve or twenty-four hours. 
It has receded and returned. Epistaxis, or an epileptic 
fit, or diarrhoea, has occurred to interrupt the normal 
course of the disease, and warn you of impending 
danger. Above all, in such constitutions the catarrhal 
symptoms do not subside on the outbreak of eruption. 
The cough continues. The child becomes restless. 
Careful observation detects dvspncea. The stethoscope 
gives signs of impeded respiration. Instead of the 
febrile symptoms subsiding on the sixth day, and the 
child expressing its desire to get up and have its toys, 
the litde sufferer continues to droop. Its hands are 
hot ; its nights unquiet. It is thirsty, and the urine is 
scanty. Secondary fever has set in. 

During the progress of secondary fever, inflammatory 
action, sometimes acute, but more commonly of a lower 
subacute kind, arises in one or more of the structures 
which were the seats of primary irritation — namely, the 
eyes, the glands of the neck, the larynx, the trachea, or 
the lungs. ^Scrofulous ophthalmia, scrofulous enlarge- 
ments of the glands of the neck, with succeeding ulcer- 
ation, laryngitis, croup, but above all, pneumonia, are 
the sequclcB of measles. Of the laryngeal and croupy 
affections 1 have nothing to offer differing from the usual 
phenomena of those disorders arising idiopathically. 
The danger is alike in both cases. Measly pneumonia, 
from its extreme frequency and frightful devastations, 
deserves a closer attention. 

Pneumonic complication occurs both in the progress 
of the eruption and during its decline. It is a slow,

creeping, iusidious form of inflatumatioii, wliicli too 
often iLrows rlie practilioiier off his guard. No positive 
complaint is made. Tlie child droops, and appears 
weak and exhausted. Imagining that the disorder has 
weakened his patient, the practitioner directs some mild 
tonic. Meanwhile, pneumonic engorgement (or pneu- 
monia in its first stage) creeps on. The lungs hecome 
more and more congested, and at length .solidified. A 
convulsive fit now takes place. Alarm is taken, and 
leeches are applied, but the mischief is irreparable. 
Dyspnoea increases, The child becomes drowsy, the 
feel cold. The pulse sinks. Fluid effusion now takes 
place from the bronchial membrane. Another and 
another fit succeeds. Rattles are heard in the throat. 
The child dies !

Such is the usnal course of rubeolous pneumonia. 
Sometimes the inffammaiion is of a different kind, 
which runs on to the rapid development of tubercles, 
and the formation of small abscesses. The child ema- 
ciates, heconies consumptive, and dies. This series of 
changes may occupy a month or six weeks. The for-

intensity, sometimes giving a decided character to the 
epideniic. In 1745, measles of this kind appeared in 
Plytnouth, and found an able historian in Dr. Huxbaui. 
In 1763, occurred the celebrated epidemic of malignanl 
measles described bj Sir William Watson with such 
accuracy, thai the disease was long known as Watson's 
measles. In 181G, a similar epidemic prevailed in 
Edinburgh. In 1S39, it was observed at Hertford 
among the children of Christ's Church Hospital, who 
are tbere educated. Tlie characteristic features of 
malignant measles are — J. Severity of the initiatory 
fever. 2. Irregularity in the course of the symptoms, 
especially in the appearance and aspect of the eruption. 
3. Severe implication of the brain. 4. Implication of 
the abdominal viscera. 5. Concomitant disorganization 
of the blood, leading to petechias and btEUiorrhagea. 

The eruptive fever is severe, and attended with 
QDUSual symptoms. The fever is typhoid, not iuflam- 
matory. The eruption appears too early or too late. 
It perhaps recedes after having shown itself, and par- 
tially reappears. The stomach is irritable; vomiting is 
both severe and protracted ; tbere is delirium, with 
wildness of eye, or coma; the belly is tender; there is 
purging of unhealthy stools ; tlie extremities are cold, 
the pulse small and wavering; on the surface appear 
petechiEe or ecchymosed patches of eruption ; the fauces 
assume a livid, or dusky red color; blood passes by 
stool; there is much oppression at the pnecordia, and 
abundant niuco-serous discharge from the chest, indi- 
cating the congested condition of the lungs and their 
mucous membrane. In these almost hopeless circum- 
stances, children may (He in forty-eight or sixty hours, 
asphyxiated by the coudiliou of the air-passages ; others 



APPEARANCES ON DISSECTION.

die of coma or convulsion ; some are worn out more 
slowly by diarrhoea and bloody slook. 

The appearances presented on dissection of those 
who die either of the malignant measles or of the tho- 
racic complication already described, present features 
which might readily be anticipated from the character 
of tlie symptoms. Tlie bronchial memhrane is spongy ; 
abundant serons efTusion escapes Irom the lungs on 
pressure; portions of their substance are consolidated; 
the larynx is (Edematous. Abscess and purulent infil- 
tration are rare. In the abdomen appear patches of 
nlccraiion, with or without enlarged mesenteric glands. 
In the ventricles of the brain, you will occasionally find 
e0usion of serum. 

I have, lastly, to speak to you of that truly frightful 
combination, measles with the tendency to gangrene. 
This is sometimes witnessed in children of the upper 
ranks who are of extremely weak habit, but all the 
worst cases appear in the half-fed children of the lower 
ranks, inhabiting damp cellars, and inhaling an impure 
air. The measles, having superadded to it such sources 
of constitutional debility, proves too much for the sys- 
tem. The first evidence of the gangrenous dispositioa 
will probably be a sloughy state of leech-bites or blis- 
tered surfaces, if leeches or blisters had been applied, 
with small ragged nlcers on the inside of the cheek, 
exhaling an offensive odor ; soon after which the trae 
cancnini oris begins to show hself. A hard round 
spot, Uke a marble, occupies the inside of the cheek, or 
a small black point appears at tlie corner of the mouth. 
A tooth drops out. In twenty-four hours, gangrene has 
spread so as to occupy a large portion of the inner and 
some part of the outer cheek ; at length the whole

PROGNOSIS IN MEASLES. 



^^eek is eaten away, and the nose and eye are invaded. 
Happily, however, death puts a period, though not 
always an early period, to this distressing scene. 

Cases of recovery from cancruni oris are seldom seen, 

except in adults. The aflectioD is not peculiar to the 

latter stages of measles. I have seen it following small 

pox, and occurring in the progress of infantile remitting 

fever ; hut there is something in the rubeolous miasm 

peculiarly depressing to the vital power, and hence can- 

Lcnim oris is much more common after measles than 

rafter any other exanlhcmatic malady. Mercurial pre- 

IparatioDS have often, but unjustly, been accused of occa- 

l^oning or at least favoring the disposition to cancrum 

|:oris. It often, however, appears where no sacli drug 

fhad been administered, and is, in truth, entirely depend- 

I ent on constitutional debility. 

The prognosis in measles is easily laid down. The 
I cause of death in the great proportion of cases is pneu- 
' monia. All symptoms indicating pulmonic cougestion, 
' and its con sequences, whether affecting the chest, head, 
f or belly, such as coma, convulsions, or vomiting, are pe- 
culiarly to be dreaded. It has generally been remarked 
that measles does not fall with such severity on pregnant 
and parturient women as the other exanthemata. In- 
deed, the mortality by measles among adults is very 
' low. In hot countries measles is not viewed with alarm, 
evidendy from the abseuce of thordcic complication. 

The following are the observations of authors regard- 
ing the proportion of deaths to recoveries ; — lu one of 
Sir W. Watson's epidemics, the deaths were as high as 
I ten per cent. Dr. Plome estimated the proportion at 
eight per cent. Mr. De la Garde states that, at Exeter, 
in 1824, he lost eight per cent. Dr. Percival, of Man- 




STATISTFCS OF HEABLES. 

Chester, lost niuety-one out of 3807, which is one iu 
forty, or two and a half per cent. Dr. Adams states, as 
the generally received opinion in his time, that commii- 
nibus anitUi, measles dues not prove fatal to more than 
three per cent. I have given (page 6) a table of the 
deaths by measles during three years. It will be seen 
that in 1839, there died, throughout England and 
Wales, by measles, 10,937 persons: this, at three per 
cent., would make the total attacked, 364,566, about 
the number of those born who attain the age of three , 
years. 

Mr. Farr's Fourth Report gives tables of the deaths, 
by measles, throughout England and Wales, for three 
years and a half, on a very extended scale. The fol- 
lowing abstract presents an interesting picture of the 
prevalence of the disease in this country, and of its 
varying intensity : —

We learn from this table that the average annual

would appear to have less influence on the mortality of

The diagnosis of measles need not detain ns. Fi 
scarlatina it is to be distinguished — 1. By ibe charai 
and duration of the eraptive fever; 2. hy the character 
and general aspect of the eruption ; 3. by the state of 
the throat. In a subsequent lecture, these points will 
be stated more in detail. From lichen febrilis, measles 
is distinguished by attention to the initiatory stage. 
This stage is four days in measles; in lichen, tweni 
four hours. 

[Chomel adds to the above dingnoslic marks of measles mentioned 
anthora, 

1, Spots like those of ecchymosis under the skin, which he saya 
' not rare, and are peculiar to measles, and seen in some of il 
forms. 

S. Sputa of a peculiar character, which he describes as consistiDg 

Opake, nummular masses, of a greyiab rolor, floating in an abundance 

I of liquid, and resembling the sputa of the second stage of phthisis. But 

ID phthisis, the fluid in which they float is cleiir and transparent, wh3o 

in raeaales it is dull, cloudy, aud lactescent. 

M. Chome! considers this an important diagnostic mark, affording aid 
in epidemics when the eruption dues not make its appearance, and 
when the eruption is suddenly suppressed. Tiiis mark can only bo 
eervioe in adults, as infanta do not eject the sputa.] 

The real difficulties of diagnosis arise out of the c 
currence of ttvo exanthemata. Measles has been knon 
to co-exist with small po.\. Mr. De la Garde has l 
corded an intercsliug case of this kind which occun

DIFFICULTIES OF DUGIfOBIB. 



at Exeter in the epidemic of 1824. Dr. Russell has 
detailed like cases occurring at Aleppo, Many years 
ago I attended, with the late Mr. Corbett, a case which 
exhibited the combined character of measles and scarla- 
tina. There was an eruption of measles, with the 
sloughy throat of scarlatina. I have put on record the 
particulars of a family invaded at the same time by 
the miasms of scarlatina and measles; one child took 
measles first, and scarlatina afterwards; the other took, 
scarlatina first, and measles afterwards. The character 
of the eruptive fever in each of the four seizures, indi- 
cated the nature of the disease which was to follow. 

Dr. Russell, discoursing on the reciprocal influence 
of small pox and measles, informs us that he carefully 
watched above 300 cases in which these diseases suc- 
ceeded each oliier, at a time when they were both epi- 
demic at Aleppo (1765). He noticed that the measles 
rarely succeeded small pox iu less than 20 days from 
the first appearance of the eruption. Several cases, 
however, were observed where small pox succeeded 
measles before the total disappearance of rubeolous rash 
from the extreniiiies — that is, on the 11th or 13th day 
of tiie eruption, lie adds, " so little did the quality of 
the first disease influence that of the second, that a 
mild distinct small pox was often observed to follow the 
worst kind of measles, and vice versa." 

Willan relates the case of a young man, aged eighteen 
inoculated for measles and cow pox on the same day ; 
the cow pox took the lead, measles following at the end 
of sixteen days. I described (page 119) a case very 
analogous ; but there measles had the start, and after 
sixteen days, cow pox bad its turn. It is singular that 



136 



PATHOLOGY OF MEASLES. 



in each case sixteen days should be the period of sus- 
pension. This, I am persuaded, was not accident 

The pathology of measles (by which I understand 
all specidations regarding the causes of the disease) af- 
fords much curious matter for inquiry. That measles 
b the product of a specific miasm, and is never gene- 
rated de novo, is now tlie universally admitted doctrine. 
Historical facts countenance this opinion. Measles 
never gained footing at St. Helena until 1808. For 
ftventy-five years it was ahsenl from the island of Ma- 
deira ; and wben, in 1808, it did invade the island, it 
found almost the whole population susceptible ; in four 
months it destroyed 700 lives. Australia and Van 
Diemen's land are to this day exempt from measles. 
They have, indeed, what is called Van-Diemen's-Land 
measles, which is a species of febrile lichen, affording no 
protection against the measles of this country. 

[Ad aiiiilo^Dus fiict to the one sUilcd respecting Mndeira, is recorded 
as liHving occurred at Tliorshnven, the capiUil of the Faro Islands. A 
writer in the London Med. 6az. (July 10, 1846, p. 83) says, " letters 
lately received from Thorshaven cnilain the intelligence that the mea- 
sles, which had not appeared in that i»lnii<l since 1T8I, and which, in 
that cliniale, always assumcH the charneler of a terrible ejiidemic, Iiad 
broken out there. Of the 800 inhabitants of that town, more than 700 
had been attacked hy it, and from 10 to IS persons daily fell victims to 
it. The only pcr!(ons spared were the native old men who liad the dis- 
ease in 1781, and the foreigners who had been attacked by it in foreign 
parts." 

These facts, interesting as they are, cannot be quoted in favor of cither 
side of the ques^on as to the origin ofineafiles, being deficient in proof 
M to the importation of the disease. We have already slated (j»age 80) 
lensons for beli'^ving in the possibility at least of the occurrence of this 
eiantbem independently of contagion. Dr. M. F, Cogswell, in a letter 
to Dr. K n. Smith, June, 1799, records two such cases [Med. Repoa., 
1709, vol. ii. p. 281), and we have also given the authority of Dr.

Lha same side. To tlie.se, we may

The statistical details already given show how uni- 
versal is the susceptibility of this contagion. The re- 
currence of measles has been recorded, but the well 
authenticated cases are few. Dr. Gaillie has put on 
record seven, of whom five were brothers and sisters. 
Four had recurring measles at the interval of sis 
months; one at the interval of twenty-one years. Dr. 
Websler has published three similar cases, where the 
intervals were respectively two years, four years, and 
si.? years. Two cases are recorded by Dr. Home. 

In all speculations on the recurrence of measles, it 
should be remembered that one form of lichcnous erup- 
tion closely resembles measles in its outward aspect, 
and. consequently, that the periods of incul>atioii, access, 
and decline, are of more value in diagnosis than the 
character of the eruption.

on tho 12t1i of April. Desquamation took place each time. {Bullet 
Gin^r, de Th6r., Sept 15, 1848, p. 239.)] 

The inoculation of measles was first thought of by 
Dr. Home, of Edinburgh, in 1758. He inoculated with 
the blood, applying cotton dipped in tlie blood of a 
measly patient to a wound in the arm. We read, that 
febrile symptoms appeared on the sixth day, of a mild 
character, and that no secondary complications ensued. 
Early in this century, Mr. Wachsel, of the Small Pox 
Hospital, inoculated a lad, Richard Brookes, with fluid 
taken from some of tlie measly (or miliary) vesicles, and 
the inoculation was successful. In 1822, Professor 
Spcranza, of Mantua, inoculated himself and six boys, 
in tlie manner recommended by Home, with complete 
success. In other trials, it does not appear that the 
resulting disorder was at all mitigated. 

The latest recorded experiments are those made in 
1SI2, in Hungary, by Dr. Katona. We are informed 
that he failed in 78 cases only out of 1112 (seven per 
cent.), and that the resulting disorder was mild, contrast- 
ing favorably with the severity of the reigning epidemic. 
No deaths occurred among the inoculated. The in- 
fecting blood was drawn from the surface most eiflo- 
resced ; we further learn, that a red spot with surround- 
injj areola followed. On the seventh day, rigors 
oeeurred, with the usual catarrhal symptoms. On the 
ninth or tenth day, eruption manifested itself, which

lately been inclined to think, that the child, whose case 
I detailed (page 119) as having undergone cow pox 
after measles, received the germ of measles and of cow 
pox at the same time ; in other words, that, unknown to 
me, the child that furnished the lymph was incubating 
the measles, with the zuma or poison of which the vac- 
cine matter had become impregnated. When the case 
occurred, I presumed that the germ of measles had been 
received b; accidental infection. 

[The cotntnunication of smnll pox to the foatiis in ut<?ro is a well 
estabtbhed foci — such commuuication in tlie case of messlos \> not well 
known. Id iLis point of view, the following is not without interest, 
takeD from Dr. West's Report on Progress of Midwifery, ic., in Brit, 
and For. Med. Rev., Oct. 1845, p. 549. 

" Dr. Hcilrick relates the hislorv of a woman, who, having been at- 
tacked by inettsles at the end of her pregnancy, gave birth, on the fourth 
day of the disease, to a female child, who was covered with the eruption 
of measle*, and was suffering from catarrh, cough, sneezing, inflamed 
eyea, iic, but recovered in a few days."] 

This brings me to the infective nature and epidemic 
diffusion of measles, which must detain us for a short 
time. 

It has been rendered highly probable, more especially 
bj a case recorded by Dr. Williams of this Hospital, 
that the blood throws off infective emanations during 
the eruptive fever, and prior to any eruption. The in- 
fective distance is unknown. It was formerly held, 
that measles sets in in January, reaches its crisis at the 
vernal equinox, and ceases in the summer solstice. 
Modern statistics overthrow all these long- established 
notions The quarterly deatlis by measles in London, 
in 1841, were 168— 147— 260— 408,— total, 973, In 
1842, they approximated still closer, being 308 — 334 —

311 — 340, — total, 1293. No such law of epidemic 
culmination and decline is here apparent. In fact, the 
recurrence and duration of epidemics is, in Kurope, 
wholly irrespective of season. In Bengal, however, the 
prevalence of measles (or Haceni) is governed by dif- 
ferent laws. There the disorder never originates except 
in the cold season. It begins about the middle of that 
division of the Indian year, and continues till the hot 
season is estabUshed. Season affects too, there, (he 
character of the symptoms. In the hot months the 
eruption is more vivid and more elevated, and the 
internal organs comparatively but little affected. In 
tlie cold season, the affection of the mucous tissues is 
best developed. 

Measles is undoubtedly increasing in severity, if not 
in quantity, in this country. In 1748 only ten deaths, 
and in 1754 only twelve, are recorded in the bills of 
mortality as having arisen from measles; whereas the 
weekly average of the last four years is thirty, and the 
annual average, 1560.

If I have rightly laid down the pathology of measlesi,! 
the principles of treatment will flow naturally from it, 1 
and in truth there never has been any serious difference J 
of opinion on this suhject of late years. In regular i 
measles, an autiphlogistic method of treatment has been [ 
advised. The only doubt that can be raised is as to I 
the extent to which such measures should be carried, I 
aud the period to which they should be protracted. 

Moderate warmth is desiral)le during the initiatory 
fever, to encourage eruption, and thus reUeve niDcoas 
congestion. This may, however, be carried too far. 
On the 1.5th June, 3 830, I attended R. W. (letatis 5), j 
who was kept so hot by blankets, flannel vests, a large! 
fire, and the closure of all doors and windows, that the^ 
cliihl was nearly comatose. Perspiration was flowingfl 
from his skin. There was dyspntra and epistaxis. Thel 
blood was goi^ing the bead and chest. The loss ofm 
some blood from the arm, a total change of regimen, 1 
and lotions of vinegar and water, soou set matters toM 
rights, aud the measles ran its regular course. I 

On the appearance of eruption, your object is simplyl 
to avoid occasions of aggravation. Let the patient he I 
confined to bed, take occasionally some castor oil and I 
a simple s;dine draught, with synipof tolu and some an- M 
timonini wine, every fonr hours. A saline powder,! 
HDch as three grains of potassie salphas, with five of! 
tUKur, may be given to children of very tender years, arm 



143 

the mistura amygdalie with nitre. To allay the cough, 
a httle syrup of poppies may be taken, especially at 
night. 

If, after the completion of emption, cough should 
remain, try what a mustard poultice, or the acctum 
cautharidis, or a blistering plaster, will do. If the cough 
still continues, mischief is brewing, which neglected, 
will lead to more serious consequences. Therefore 
apply one, two, or more leeches, according to the age 
of the child; and if the symptoms indicate confirmed 
pneumonia, take away some blood, from the arm if you 
can, — if not, from the jugidar vein. Do not attempt to 
combat measly pneumonia by purgatives, nor by calo- 
mel and opium. Tartar emetic, pushed in the first 
instance to full vomiting, and tlien given in more mode- 
rale doses, is sometimes sufficient, but it cannot generally 
be relied upon. 

Pt U important Lo bear in mind llist dyspnrmi, severe coiigii, and a 
deep color of till? face, do not alwaya with certainty indicat*> inflammntory 
■flection of either the bronchinl tubes or of the longs thentsi-ltes. The 
tympUiras may all be produced by a congested Btatc of the mucuua 
Membrane of tlie respiratory passnges, as a part of the disease, anal<^ua 
to (iist state of hyperemia upon wliich the eruption on the skin depends, 
and rottj rapidly disappear as the eruption bceoines de\'eloped over the 
snrliice. The continuance of tliese symptoms after the eru/ilion is iwff 
out, is indicative of more serious trouble, as our auihor remarks.] 

Id the malignant measles, with cold exlremities, 
diarrhoea, and receding eruption, no plan of treatment 
is very successful. Diarrhoea must he restrained by 
one, two. or three grains of Dover's powder, given along 
with half a grain of calomel, every four hours. The 
child should be put into a warm bath, and mustard 
poultices apphed to the feet and epigastrium. Ulisters

The extent and severity of scarlet fever at the present 
time are such as to demand from you the most patient 
attention and dihgent study. It is obviously an in- 
creasing malady, and seems likely, in after times, to 
occupy that painful pre-eminence among the fatal dis- 
eases of early life which small pox formerly enjoyed. 

By whom the term scarlatina was first used is not 
well known; perhaps by Sydenham, for I cannot find 
anv traces of the word before his time. The mild vari- 
etv of the disease described bv him existed in the East 
at a verv earlv date, but vou woidd in vain search for it 
in the writina^s of the ancient Greeks and Romans. It 
probably invaded the world soon after small pox and 
measles had made their debiii, for the Arabian physi- 
cians describe a species of measles, which, from the 
extent of desijuamation, we may be assured was scarla- 
tina. In the ages which succeeded, scarlatina continued 
to be confounded with rubeola. 



FIBST NOTICEa OF SCARLATINA. 



147 



In til e year 1610 an epidemic angiaa, with scarlet 
eruption, raged in Spain, from which country it passed 
over, in 1618, to Naples, theu governed by a Spanish 
viceroy. We naturally look therefore to Spanish and 
Italian authors for the first description of the anginose 
or malignant scarlet fever. The early Spanish writers 
are Ludovicus Mercatus (1G12) and Michael Heredia 
(!G:?6). The latter is peculiarly full and clear in his 
descriptious. The Italian authors are Sgambatus "(k 
pestUente faucium affcctu Neapoli steuietUe" (1620) ; 
and CEtius Clems " de nioibo siran guia/orio" (163G). 
Sennertus noticed the same disease in Germany aboat 
1625. Dieuierbrocck of Utrecht, in 1640, described 
under the title of purpura, a disease which he believed 
to be a variety of measles, but which was obviously 
scarlatina. The milder type of the same disorder was 
seen by Sydenham in London between the years 1670 
and 1675. He describes it as a disease more in name 
than in essence, and fatal only through the officiousness 
of the physician. He was ignorant of any connexion 
existing between it and the angina putrida maligna of 
the Continental authors of that day. 

Scarlet fever, in its mild form, first reached Edin- 
burgh in the year 1680. Sir Robert Sibbald, physician 
to King Charles II., for Scotland, says, " It is so recently 
introduced, and so little understood, that I cannot ven- 
ture to ofi'er any observations either on its theory or 
treatment." Morton described scarlatina as it appeared 
in London in 1089 and the three following years. It 
was a severer epidemic than that witnessed by Syden- 
ham, but Morton was so fully convinced of its intimate 
relation to measles, that his details cannot be trusted. 

Id 1747-8, London experienced a severe scarlatinal 



150 DIVISION INTO SPECIES. 

1. The phases, modifications, or types of the disease ; 

2. the mode of its propagation ; 3. the amount of mor- 
tality which it occasions ; and 4. the treatment adapted 
to its varied aspects. 

I have explained to you that the fever now to be 
treated of does not originate (under common circum- 
stances) from any spontaneous movements in the blood 
or humors of the body. A zuma, ferment, or poison^ 
must have access to the body, before the blood is set in 
motion, so as to develope the phenomenon now called 
scarlet fever. The effects produced by that poison may 
be exerted on the skin alone, and then the accompany- 
ing fever is slight ; or it may develope a more serious 
kind of ardent fever, and then the skin and throat will 
both exhibit appearances. It may so seriously affect 
the whole system as to produce intense fever, in which 
case the throat receives nearly the tvhole shock, the 
skin being only partially affected. Nay, in some 
extreme cases, the nervous system shall be so com- 
pletely depressed and subdued by the virulence of the 
miasm, and the mass of blood so thoroughly poisoned 
and disorganized by it, that all the ordinary appear- 
ances of scarlatina are masked. Petechia?, coma, and a 
slongliy state of the throat, alone appear. liifc rapidly 
yields under snch an attack. 

From this rude sketch of the effects of the scarlatinal 
miasm, you will see that a gradation exists in nature 
from the mildest to the most malignant, and that the 
external appearances vary with the character of the 
fever. A division of scarlatina into species has been 
made, but remember that it is artificial. Nature creates 
genera and individual cases, but species are the imper- 
fect arrangements of man. With this reservation, I

sliall avail myself of the threefold division now in gene- 
ral use, and sliall treat of the two extreme links in the 
long chain of phenomena, and the intermediate variety 
— that is, I shall describe to jon, 1. Scarlatina initis; 
2. Scarlatina anginosa ; 3. Angina maligna. 

The poison of scarlatina, whatever aspect it stibse- 
qucnlly assumes, has a very short period of incubation. 
It invaded my own family in 1839, Rigors occurred 
to one member of it on the last Saturday in April. On 
Sunday, languor and lassitude, with dryness of skin, 
were the chief symptoms. At six o'clock on Monday 
morning, eruption appeared. On the following Satur- 
day, at two P.M., my eldest daughter sickened, so that 
the incubative period coald not have exceeded seven 
days, and was probably only six. Withering says that 
he has known patients begin to complain as early as 
the third day from exposure to the contagion, and I 
cannot contradict the assertion, though I never saw 
incubation so rapid as this. Wc may fairly state the 
incubative period as varying from four to eight days. 

1. In the mildest form of scarlatina, it often happens 
that the first symptom is the rash. No febrile disturb- 
ance whatever has preceded. More commonly, there 
is a certain amount of fever, the symptoms not present- 
ing any marked characters. Rigors, beat of surface, 
vomiting, restlessness, thirst, languor, lassitude, muscular 
debility, and headache, are the chief complaints. On 
ihe succeeding day, the rash appears. Some authors 
would persuade us that the rash may be delayed to the 
third or even the fourth day from llie rigor. These 
observations, however, made when the diagnosis of 
measles and scarlatina was yet in its infancy, cannot be 
trusted to. 



162 



SCABLATINA HITIS. 



Tbe efflorescence in scarlatina mitis is first perceive! 
ou the trunk, arms, and thighs; very often nothing" 
appears ou (he face, when these parts are covered with 
eruption. In less than twenty-four hours, it spreads 
over (he whole \)ody. Everything is rapid about scar- 
latina — rapid incubation — rapid eruption — rapid course. 
6ome(itnes the redness is continuous ; but much more 
generally it is distributed in patches of no definite 
shape. The color is a bright scarlcl, precisely that of 
the bmled lobster. When closely examined, it is found 
to consist of innumerable small red points, or dots. In 
the greater number of cases, the finger passed over the 
surface is not made sensible of elevation or roughness. 
Sometimes, especially on the breast, and parts kept 
very warm, the feehng of papula is given. This, how- 
ever, can only occur when there is fever, and sufficient 
force in the heart's action to distend the cutaneous 
Capillaries. In the mild fonn of scarlatina I am now 
describing, this will not often happen. The redness 
of scarlatina, like that of erysipelas, disappears on 
pressare. 

[Tbe color of scarlet fever has long beeD described as unifonnlj spread 
over tbe surfnce, as if the part had been rubbed over with the juice of 
nspberries — but tbis requires some moditicntion. It is not uniform u 
to lint, but is composed of a bright red layer, on which arc ecAttered 
great numbers of very small points of a deep red color, which give ths 
eruption a markedly jniob^d aspect. These two shades of redness vary 
in inlt^nsity in diffureul cases, and the predominance of intensity of the 
one or ihe olber gives tbe surface a brighter or a deeper tint. Towards 
tbe dose of the eruption, the more uniformly difiiised layer gradualty 
bAe», while the red points retniu more of their original color, and this 
gives tlie surbce, during this slate, a punctated appearance, the dislribo- 
tion of which is rr>gul3r, and has been compared, as far iis nrrangument 
of the points is concerned, to the granite of painters. This npp<>nranca 
aotaetinies exists during the whole course of the disease- lu measles, 



on the contrary, besides the decided diff.Ten n hu h fiots a a 

alwnys irre^lnr, witlioui Fiymmetrr, and dilfi- n )i!if ze d 1 a 

tioa. This is eajiecially evident during the dei.1 f I nip n 

Hence, rej^ulnrily is a characteristic mark of eca lu u ad (nik 
of measles.] 

For twenty-four hours tlie child is restless, and rofusos 
his food. On the third day yoii will find him sitting 
up whh his toys. The rash is receding. In two days 
more, ilie httle patient is convalescent. I have often 
examined the throats of children affected with the 
scarlatina niitis, and not seen the slightest trace of 
angina. The poison, therefore, may circulate w-jthoot 
any throat affection. Well might Sydenham call this 
a disease in name only; it is net'crtheless worthy of 
your study, in order that you may trace (he steps by 
which it ascends into the malignant cynanche. 

2. I now come to the scarlatina anginosa, the primi- 
tive type of the disease, or that from which all the other 
varieties diverge. It is, as might hence be presumed, 
by far the most frequent form in which the miasm 
developes itself. Scarlatina anginosa is a disease which 
more than any other that I know of will call into play 
yonr pathological learning, and all yonr therapeutical 
skill. It is a disease wliich may be materially aided by 
medical art. It is a disease in the management of 
which medical men are more apt to differ tliau perhaps 
any other. It is, lastly, a disease which, from its 
rapidity, leaves you little time for reflection. You must 
have studied it well beforehand, and determined how to 
act in cases of emergency.

meet your observation in the course of scarlatina angi- 
nosa, varied as they are by season, habit of body, 



154 CHARACTER OF ACCOMPANYING FEVER. 

climate, and epidemic character, would profit you bat 
little. I shall rather direct your attention to the struc- 
tures and organs affected, and thus associate symp- 
tomatology and pathology. Remember, that in this 
complaint you have four classes of symptoms — 1. 
General fever or pyrexia ; 2. affection of the skin and 
cellular membrane; 3. affection of the mucous mem- 
branes ; 4. affection of one or more of the great viscera 
— the brain, lungs, or heart. 

(J.) The accompanying pyrexia may be, as I have 
already said, either inflammatory or typhoid. In the 
majority of cases, the inflammatory character prevails, 
the heat of skin being more remarkable than in any 
other known malady ; it gives to the hand the feeling 
of scorching. The heat indicated by the thermometer 
often rises to 104, and Dr. Currie says he has seen it 
at 112. The body is living in a furnace of its own 
making. Let not this circumstance pass unnoticed by 
you. The human body is prepared for a heat of 96. 
Its functions then flourish ; but it will not bear to have 
its internal heat much lowered, nor materially raised. 
A heat of 105, 108, or 110, no system can long with- 
stand ; it burns and dries up everything; it kills the 
cuticle and the hair, injures the delicate structure of the 
eye and car, deranges the liver and the brain. I attri- 
bute a large share of the evils of scarlatina anginosa to 
the intensity of the animal heat. The blood is not 
always buffy in scarlatina, ahliough the skin be so hot, 
and the pulse rapid ; there is febrile tumult, but not 
inflammation. Inflammation may supervene, but the 
pulse will then be not merely frequent, but hard and 
incompressible. 

[It may probably with wifcty bo said that, at the present time, and 



CHARACTER OF THE ERUPTION. 



fcr aereral years past, in this country, tlie type of sc«rlatina hRs been 
dnndedly lyplioid in ila character. It is comparatively rare that we 
find that great beat of skin described by our author, as wt-11 as by 
oUien, as acconipnnying this disease. The temperature, even in this 
forni, i» not unfrequently about natural, and Bometimea even below tbis 
stjuidard. With this temperature of the skin, an nnginuse affection of 
the worst kind is very often associated.] 

The true cbaracter of the pulse in scarlatina is rapid, 
seldom less than J20; the tongue is white; and as the 
mucous covering of ihe tongue is affected, like other 
mucous surfaces, %vith eruption, so the red and elongated 
papillae protrude through the fur, or diseased secretion 
of the month, presenting that peculiar appearance called 
the strawberry tongue. Sometimes it is purely red. 
The other febrile symptoms are the same in kind, but 
exceed in severity those of scarlatina simplex. The 
headache is more pungent, and often accompanied with 
delirium. Muscular pains are severe, and the back of 
the neck is often very stiff There is a feeling of ten- 
sion and fulness in the fingers, evidently from the force 
of the blood impinging on the extreme capillaries. 

(2.) But to pass to the affection of the skin and sub- 
- jacent cellular membrane. The rash is vivid in color. 
I once saw it elevated in circular patches, and some 
physicians called it urticaria rubra febniis ; but it 
was genuine scarlatina, with sloughy throat. Nothing 
is more desirable than that the eruption should be 
accompanied by a moist state of the surface. There 
is ibea, as we might reasonably expect, niucli less risk 
of visceral congestion. The determination of blood to 
Ihe skin is sometimes so great, that miliary vesicles 
appear interspersed among the patches of efflorescence 
(especially on the breast). This variety has been called 
scarlatina varioloides. With ordinary care, however, 



156 CHARACTER OF THE ERUPTION. 

this will never happen. It is attributable to the nimia 
diligentia either of the nurse or of the doctor, of which 
Sydenham complains. Very often the rash recedes for 
a few hours, and then recurs. Sometimes it appears 
only partially, as on the thighs ; white blisters some- 
times accompany or succeed the rash. 

It is very common to see the cellular membrane, 
especially that of the neck, taking on a kind of inflam- 
matory action. The fingers stiffen ; the neck swells ; 
the parotid glands enlarge ; tlie jaws are with difficulty 
opened. 

[MNf. Baitliez and IlilHet mention six to eight days as the ordinary 
duration of the eruption of scarlet fever in its normal form. They say 
that it requires a longer jieriod to develope itself than that of measles ; 
and jtersists longer at its maximum, that is, 24, and even 48 hours. 
They have seen the eruj)tion of scarlet fever last only five days, and have 
also seen it l:ust seven, eight, or even ten days ; but never beyond ten 
days. (J/i/Z. dcs Enfants, t. 2, p. 5*78.)] 

(3.) The condition of the mucous structures of the 
nose, mouth, palate, and larynx, will demand a much 
more extended investigation. 

Sometimes the very first intimation of the real nature 
of the disease is given by a feeling of roughness of the 
throat, and some pain in deglutition. On examining 
the fauces, the palate, uvula, and tonsils appear red and 
swollen ; and should the fever be active, portions of 
coagulated lymj)h will be seen efliised. These are 
often mistaken for ulcers; but in many most severe 
cases of anginose scarlatina there is no actual breach of 
surface — only excessive engorgement, with efliision of 
lymph. 

Deglutition is now so painful, that the patient will 
rather suffer tliirst than attempt to quench it with the 



AFFECTION OF THE THROAT. 157 

certainty of excessive pain. Be on your guard when- 
ever excessive pain occurs, wheilier it be Iq pleurisy, 
jaundice, enteritis, or scarlaiiiia. Remember that death 
may be the conseijuence of excessive pain (as in cru- 
cifixion, or the torments of the Inquisition), or, if not 
deatb, at least serious mischief. In tlie case of angiaa, 
excess of pain is followed by extension of ioilamQiation 
to the celhilar membrane subjacent to tlie ear, and to 
the brain. 

It is often difficult to examioe the state of the throat 
from the exteut of cellular inflamuiation, but you may 
always form a good judgment of what is going forward 
there by taking as your guides the pulse, and the 
degree of pain iu deglutition. That actual ulceration 
does lake place in a certain proportion of cases is uude- 
DJahle, hut the former is the more frequent pathological 
condition. I remember seeing a young lady many 
years ago (Miss E. H.), of exceedingly full habit, where 
the determination of blood to tiie throat was so exces- 
sive that respiration became impeded; the pulse began 
to give way ; and timely scarifications alone saved the 
patient's life. 

AVhile all this is going on in the throat, the mucous 
membrane of the nose becomes involved. An acrid 
sanies, or ichor, begins to flow from the nostrils. The 
membrane itself appears red and swollen. The sense 
of smell ceases. Inflammation next extends along the 
Eustachian tube to the inner and outer ear. An acrid 
discharge, sometimes of a purulent character, distils 
from the ear. Tiie ear is painful. The inflamniation, 
if intense, may destroy the interior structure of tlie ear. 
The ossicula auditus may slough away, the tympanum 
fill up with granulations, and total deafness ensue. 



158 



IMPLICATION OF THE EYE. 



Bat this is not all, nor a tithe of the mischief which 
may take place wiiile the scarlatinal poison is in pro- 
cess of concoction, and struggling, like a giant in prison, 
to work its way out. The eve may become affected, 
and two things may here take place, both requiring 
your attention. The eye itself may take on inflamma- 
tion, and this, if neglected, may go on to actual destruc- 
tiou of one or both eyes. lu 1832, at the late Sir 
David Berry's, I played a game of chess with Mr. Sey- 
mour, who lost both eyes by this disease. He had been 
seized with an intense form of scarlatina anginosa, at a 
village in the west of England, where ihe medical man 
wanted knowledge to guide him in the required treat- 
ment. This young man ought to have lost thirty 
ounces of blood from the arm. He was never bled at 
all The poison, raging uncontrolled, destroyed both 
eyes. 

But further; the inflammatory action may lay hold, 
not of tlic eye, but of the cellular substance within the 
orbit in which the eye lies imbedded, 1 have never 
seen this described, and have seen but one case of it, 
that of Mr. Hobson, Surgeon, of Great Marylebone 
street The ear was here first affected, then the cellu- 
lar membrane of tlie orbit. The eye was saved only 
by the most vigorous measures — bleeding, cupping, 
physicking, and starving, continued for many weeks, so 
difficult was it found to subdue an inflammatory dispo- 
sition once sot up in this structure. Had it been small 
pox instead of scarlatina, where the disposition of 
vessels to pustulation is so strong, nothing could have 
prevented abscess, I was assisted in the management 
of this most difficult case by the late Dr. Warren, and 
Mr. Alexander of Cork street. 



CELLULAR COMPLICATION. 



159 



^^^^PTbe extension of inHammaiioD lo tbe larjnx is next 
to engage nur attention. This, too, has received but 
little notice from authors. In November, 1842, 1 was 
called in to witness the sudden extension of the angi- 
BOse inflammation to the larjnx. The croupy respira- 
tion was soon succeeded by convulsions, and the child 
rapidly sank. 

(4.) So much for tbe implicatioa of structures situate 
near to tbe fauces, and suffering by virtue of their jiroxi- 
mity to the primary seat of disease. I must now advert 
to the more serious iinpUcation of deep-seated and vital 
organs. Mr. Dry, of Tottenham Court-Road, a man 
in tbe prime of life, of good constitution, took scarlet 
fever in November, 1842, When I first saw him, the 
rash was abundant, and the throat was evidently the 
seat of intense inflammation, aiibongh from cellular 
complication it was diliicult to examine it. Above all, 
the brain was affected. The patient had got out of 
bed, and was crouching down in a comer of tbe room 
in a state of high delirium. The eye was suffused. 
The skin was cooled down by exposure to tbe cold air. 
The state of delirium continued many days, but was 
idtimately subdued. 

Sometimes affection of the brain shows itself with 
less of violence. My eldest girl, during her illness, cou- 
tlnnally repeated tfie Lord's prayer. These more 
urgent symptoms will sometimes show iheuiselves very 
unexpectedly. Never, therefore, be tlirown off yoar 
guard l)y the apparent mildness of the symptoms for 
the first two days. The third is tbe day of danger, 
when the rash begins to subside, and when tbe poison, 
stjl) active and driven from the exterior, vents its fury 



160 IMPLICATION OF THE HEART. 

on some internal organ. In a few hours, irreparable 
mischief may be done. 

The lungs are sometimes the seat of inflammatory 
engorgement. I attended, many years ago, in Broad 
street. Golden square, a young man with scarlatina, where 
urgent dyspnoea and distress about the praecordia indi- 
cated a gorged state of the lungs or great vessels about 
the heart. Timely venesection saved his life. That 
an affection of the heart, particularly of its interior 
structures, often complicates the phenomena of scarlet 
fever, I cannot have the least doubt Mr. Snow pub- 
lished cases of complication of pericarditis with this 
disease several years since, and Dr. S. S. Alison has 
more recently directed attention to the subject Mr. 
Snow conceives the pericarditis to be the result, not of 
the fever, but of the renal disease which succeeds to it, 
and which may give rise to pericarditis, wholly inde- 
pendent of the previous occurrence of scarlatina. This 
complication has also been mentioned by Dr. Golding 
Bird and by several other writers. The intensity of 
the febrile action, the highly oxygenated character of 
the blood, and the increased temperature at which it 
circulates, would lead us to expect such complication. 
The frequency of consecutive dropsy corroborates the 
same pathological doctrine. I may mention one 
strongly marked case, though, in so doing, infandum 
rcnovo dolorem. A lady was seized w ith scarlatina at 
the period of parturition. The labor was long and 
severe. She perspired profusely. The heart labored 
violently. The next day scarlatina appeared. The 
heart, exhausted by the preceding efforts, gave way, 
and in about fifteen hours from the appearance of erup- 



ANGINA MALIGNA PVTRIDA. 



161 



tion, became engorged. A friglitfu! feeling of suffocation 
sapervcned, and tlie pulse for a few minutes was imper- 
ceptible at the wrist. This feeling subsided, but the 
heart never regained its natural condilion. Dyspnoea 
increased, and iu twenty-four hours more, the LIueness 
of countenance and iucipient delirium showed that the 
lungs were implicated, and that waves of ill-oxygenated 
hlood were permeating the brain. Twelve bours longer 
of this semi-asphyxiate state closed the sad and painful 
scene. 

3. The angina maligna putrida (the ulcerous sore 
throat of Fotherglll, the cynanche maligna of Cullen) 
next claims your attention. Bear in mind, that in 
nature, tlie type last described slides into this, the fever 
gradually losing its inflanmiatory, and assuming more 
and more the typhoid character. 

The initiatory symptoms of the malignant scarlet 
fever are distinguished from those of the other varieties 
only by their intensity. An irritable state of the sto- 
mach and bowels, vomiting, and diarrhtca, are frequeat 
occurrences. Headache, pain of tiie back, prascordial 
oppression, and stJlTness of the neck, are present in con- 
siderable severity, with great dejection of spirits. The 
pulse is small and fluttering. The eyes appear heavy 
and suffused. There is great debility. The patient 
lies on his back and talks in a whisper. 

The poison first localizes itself in the throat, which, 
on inspection, appears stcolkn and livid. A disagree- 
able foetor is perceived in the breath, which rapidly 
increases. Ash-colored slonghs occupy the tonsils. 
Ulceration and often extensive gangrene destroy a large 
portion of the mucous membrane. The voice becomes 
hoarse and hollow, and respiration is performed with a 



162 SCARLATINA WITH COLLAPSE. 

noise like that of one strangling. Hence the Spanish 
name for tlie disease, garotillo. The throat is clogged 
with a viscid phlegm. The nostrils pour forth an abun- 
dant and acrid sanies, followed by excoriation of the 
lips and ulceration of the angles of the mouth. 

Delirium, often of a very fierce and unrcstrainable 
kind, seizes the adult I have seen two patients in this 
disease in the most raging phrensy — jumping out of 
bed, naked, and literally dying on the floor of the 
chamber. No spectacle more awful can be witnessed 
in Eg}'ptian plague. 

[Dr. Cathciirt Lees mentions (Dublin Med, Press, July 3, 1850) a 
peculiar form of delirium resembling delirium tremens, and successfully 
treated by opium, >ihich he thinks has not been sufficiently noticed by 
authors on this subject. In one case, in a very old person, in ^hich he 
was unwilling to give opium, stimulants were used with success. 

The lato Dr. T. F. Cornell, of this city, described two forms of 
delirium in scarlet fever which had come under his observation requiring 
stimulants : one form in which they should be gradually but pirscvirhtf/If/ 
administered, and another in which they should be freely triven from 
the Ix'Lriniiinir, and cites ciises in illustrati<»n.

In some instances the bronchi become congested, and 
diflicult breathing is added to the other troubles. In 
another class of cases, the mucous membrane of the 
stomach and intestinal tract receives a large share of the 
febrile impetus. Diarrha^a (scarcely to be restrained), 
witli hiccup, distension of the abdomen, ischuria renalis, 
and an extreme sense of exhaustion, characterize this 
most formidable variety of the disease. In the most 
aggravated of all the cases, an a'dcmatous condition 
of the extremities, a bloated and cadaverous aspect of 



SCARLATINA WITH COLLAPSE. 163 

countenance, excoriation of the arms and buttocks, a 
hard, dry, and brown tongue, precede the fatal event 
All the circumstances conspire to show the awful 
derangement taking place in the nervous and cu-culating 
system through the intensity of the generating poison. 
The blood collecls and stagnates in the mucous mem- 
branes of the whole body (thoracic and abdominal), as 
well as in the liver ; and that blood is of the most 
depraved and vitiated quality. Such blood permeating 
the brain, hver, and heart, destroys their functions, and 
death ensues. You may examine the body, but the 
precise cause of death is not thereby manifested. You 
will find probably great destruction of ihe throat by 
sloughy ulceration or gangrene — turgescence of all the 
mucous membranes — engorgement of the substance of 
the lungs, or liver, or both — effusion of a bloody sanies 
into one or more of the great serous cavities, but the 
condition of the blood is the real cause of death. The 
palicnt dies of acute malignancy. 

It is encouraging for you to know that bad as these 
cases are, nature does not always give way under them. 
Dr. Huxham relates an extraordinary instance of reco- 
very under circumstances apparently the most hope- 
less. You will naturally ask, what becomes of the 
skin during this burst of gangrenous angina with 
cerebral complication, gastro-enteric inflammation, and 
hepatic congestion l I will tell you. In some cases 
Aere is considerable efflorescence, but tlie color is no 
Ifinger scarlet. It is livid. It appears and recedes. It 
b accompanied with itching, and occasionally petechia 
appear, interspersed among the more vivid patches of 
eruption. 

There are cases, very sad ones, occurring both to 



adal&i and children, wbere uo afibction of the skin takes 
place at all. Some years ago, I attended, with Dr, 
Neviuson, Mrs. Mason, of Great Marylebone street, and 
her two growu-up daughters. In each of the three 
cases the nervous system was utterly prostrated, or in 
the state of coi/apse. There was no violence, no deli- 
rluiu, no rash, no struggling for breath ; but the pulse 
was small, tlie skin cold, and the whole system depressed 
by tlie intensity of the poison. Neither wine, nor 
brandy, nor capsicum, could put life into iheui. They 
sank, one after another, without any attempt to rally. 
It was difficult to believe tlie disease scarlatina, hut the 
eldest son took it in the usual form, recovered, and pat 
that matter beyond doubt. 

I proceed next to describe the sequel* of scarlatina, 
as well of the mild as of the anginose and ulcerous 
kind. The very mildest form of scarlatina simplex is 
not free from tlie risk of some unpleasant sequels. 
That which is most usually seen is a febricula, with 
swelled glands of the neck, and discharge from the ear. 
The skin is hot, the tongue white, and the alvine secre- 
tions depraved. 

1. When there has been any serious anginose affec- 
tion, the cellular membrane of tlie neck \vill often take 
on inflammation. Erysipelatous redness of the neck, 
with great hardness and sweUing, are perceived. The 
cellular tissue sloughs, and this sloughing, if extensive, 
brings hfe into hazard, especially in infants, where the 
vis vitsE is low. The danger is less in adults. On the 
15lh December, 1842, I attended, with Mr. 8quibb, a 
chdd who died in this state, with accompanying coma, 
who had struggled successfully through the lirst period 
of the disease. Suppuration of the cellular membrane

of the ueck is often so extensive that long and deep 
incisions into the neck are required to afford the neces- 
sary vent to the sloughs. I ouce saw ahscess extend to 
the body of the parotid gland.

2. Dest|uamation of the cuticle is quite pathogno- 
monic of scarlatina. It is hardly ever absent. In all 
bad cases, the hair comes off too, as indeed it does after 
all long fevers, accompanied (as all long fevers are) 
with dryness and great heat of skin. The nails are 
sometimes thrown off, and some cabinets contain gloves 
of cuticle and uaiL It is a curious speculation whether 
this destruction of parts ends with the cuticle, whether, 
in feet, portions of other structures may not be killed in 
like manner as the cuticle, and regenerated during the 
convalescence.

of 3 and 7, while the second set of teeth is in process 
of formation, it very frequently happens that their

proportion of such cases, the urine is loaded with alba- 
men, and of low specific gravity. 

This circumstance has induced some pathologists in 
recent times to connect scarlatinal dropsy in an especial 
manner with an affection of the kidney, congestive or 
sub-inflammatory ; and undoubtedly this is an import- 
ant addition to the pathology of scarlatina. Dr. James 
Miller, in a work entitled, " The Pathology of the Kid- 
ney in Scarlatina," considers renal implication as an 
important feature in certain cases, even from the outset. 
He believes that the scarlatinal miasm fixes itself, occa- 
sionally, on the kidney as it does on the mucous 
textures of the throat, and that the development of this 
renal complication gives a character to the subsequent 
phenomena, leading more especially to dropsy and con- 
vulsion. These cases he proposes to distinguish by the 
title of Renal scarlatina. The occurrence of bloody 
urine in certain cases of scarlatina proves that the 
blood-vessels of the kidney are sometimes highly con- 
gested. In a case seen by me in 1848, and recorded 
in the first volume of the London Journal of Medicine 
(p. 451), the left kidney ultimately took on inflamma- 
tory action, and an abscess was found, after death, 
imbedded in its substance. The frequency of dropsy 
as a sequel in scarlatina, and its rarity in the secondary 
stages of small j)ox and measles, admits of a satisfactory 
explanation on the pathological principle so ably illus- 
trated by Dr. Miller. 

[Albumen is not always pro^ont in scarlatinal dropsy, as our author 
intimates. In 00 cases out of 100 in an epidemic in Berlin, in 1840, 
in which the urine was tested, I>r. Philipp never detected the presence 
of albumen by heat alone, and in only a few cases by nitric acid. 
Dropsy invariably occurred in cases which were not carried ofi* early, 



JITIHAL DaOPBT^ 169 

and began to appear, in a more or less eevere form, from llie twelflJi dny 
bi the fourth or fifth week after dcsquaiiiiilion had comraenced. Not 
one CA»e of dropsy proved fatal. {Brit. i»d For. Med. Hev., Jan, 
1841.)] 

Scarlatinal dropsy may assume any of Uie usual forms 
— anasarca, ascites, Iiydrothorax. Anasarca is infinitely 
the most common, perhaps in the proportion of ten to 
one. Sometimes the three are associated. We may 
then rest assured that the heart has become impUcated 
iu the course of the disorder, and that some serious 
impediment to the free course of the blood exists within 
or about the heart — probably a deposition of lymph 
about one or more of the valves of the heart, which 
careful auscultation will detect. These cases may 
nearly be despaired of I have seen simple ascites suc- 
ceeding scarlatina, depending upon inflammalion of the 
peritoneal coveriug of the liver, and yielding to leeches 
and saline purgatives, 

[Dropsy may auperveoe in scarlet fcver in two diflerent ways : — 

1, Suddenly, distending the cellidar Bubatance of the whole body, 
«nd extending even to the cavities, within twenty-four or tliirly-sii 
boars, with fever, and almost entire auppression of urine, and very rapid 
pulse. Tljis furm occurs quit« as often, and perhaps mom so, after mild 
Attacks of the disea»e. 

2. Qraduaily, with little or no fever, first showing itself by puffinesa 
about the eyes, or swelling of the whole ^e, or of the ankles, or of all 
theso parts at the same time.] 

The anasarca succeeding scarlatina is cnrable in a 
large proportion of cases — a circumstance which ren- 
ders it probable £hat tlie condition of the heart, kidney, 
or other viscera giving rise to it, is one of congestive 
rather than of pure inflammatory action. 

It was a favorite notion of physicians in times past, 
that scarlatinal dropsy depended on (feiiVeVy of the capil- 



170 8CARLATI1IAL DROPBT. 

lanes, and was to be combated by tonics and wine. 
This doctrine mnst have been encouraged by the resnlts 
of practice, or it never could have enjoyed such popa- 
larity ; and this is true. I have seen weakly children 
become anasarcous after scarlatina, and recover by the 
aid of wine and bark. But very many cases so treated 
would be exasperated. The urine would become still 
scantier, still deeper colored. The oppression of the 
breathing would augment, and they wocdd die at length 
with the thorax full of water. 

Hydrothorax succeeding scarlatina in the adult, still 
more commonly in children, may advance without 
attracting attention. Some years ago, a gentleman 
having passed through scarlet fever, b^n to conva- 
lesce, but his recovery was neither rapid nor satis&c- 
toiy. Symptoms were not uigent, and attracted no 
particular notice. He walked out one morning to his 
club-house. On returning, he fell, and was car- 
ried home a corpse. His chest was found full of 
water. 

Therefore, watch carefully the secondary fever of 
scarlatina. Watch the period of convalescence, even 
though no fever developes itself. Convince yourselves 
that the kidneys secrete urine of healthy, and not of 
albuminous quality. If fever hangs about the patient, 
and ill-defined symptoms harass him, keep your eye 
and ear upon the chest, so that you may early detect 
any unusual murmur indicative of cardiac disease, or 
any evidences that the lungs are congested, or the 
pleural sac distending with fluid. See that the pulse 
be soft and the tongue clean, ere you take your leave.

SCARLATINAL CONVULSIONS.

a system suffering under the secondary fever of scarla- 
tina will not regain its healthy action. 

[For A summary of the views of different pathologists in relation to 
dropsy following scarlet fevtr, see Appendix H.] 

6. The last of the sequelae of scarlatina, and happily 
the rarest, is convulsion. Not more than one out of 
eighty cases will be found thus affected. Convulsion 
may accompany the development of fever, or it may 
he deferred, and occur unexpectedly, when a hasty 
observer might consider convalescence as confirmed. 
The period of its accession, therefore, may vary from 
the third to the fortieth day from the invasion of fever. 
The pathology of scarlatinal convulsion has not yei 
heen iuvestigated with all the accuracy which is desir- 
able. It appears to be owing, in some cases, to disor- 
ganizing processes going on in the brain. In others, it 
perhaps depends on the condition of the blood which 
the heart is propelling towards the brain. Scarlatinal 
convulsion is accompauied by a buffy state of the blood 
and inordinate action of the heart. Convulsion some- 
times succeeds to dropsy, and the two affections are 
pathologically allied. The occurrence of convulsion in 
scarlatina always betokens great danger. I have notes 
of seven cases, five of which died, and two recovered.

from the vagina in sicBrlatina, which Le considers as iraporttint ia rela-

in 1849-40, in 23 female patients under hix care, all of whom were 
cleanly and well nursed, there were 12 cases of well marked vnginilis. 
Of these 23 paUents, two only were above fourteen years of age, and

dme were req>ectivdj 26 and 28 yean of age, and both married, and 
both of these had acute vagiiiitis much more severe than any of the 
difldren. He says that he was so much impressed with the importance 
of averting or preventing this aflfection, that, in every female patient, he 
directed careful ablution of the parts, at least twice every twenfy-lbur 
boon. He regards it as ^ a not unlooked fer extension of the exanthe- 
matous inflammation of the skin, analogous in its nature to what is 
often met with in the mucous linings of the nose, ear, air passages, and 
intestinal canaL" 

Wiy neA, or contraction of the stemo-deido-mastoid muscle, is 
another, and occanonally very trouUesome sequel of this disease. Ji 
aometimes goes off spontaneously in a few days, and at other times lasts 
for months, and even for years, and can then only be relieved by an 
operation. 

Dr. Golding Bird alludes to peculiar pains, at first nght apparently 
of a rheumatic character, limited almost entirely to the lower limbs, as 
fidlowing scarlatina — not constant, but apparently of a spasmodic or 
cramp-like character. {Ou^i Hiup. jBep., April, 1845.) 

The frequency of occurrence of sequehe in scarlet fever is said by Dr. 
Bird to be in the inverse ratio of the severity of the attack.]

Scarlet fever is ondoubtedly an increasing malady in 
this country. The delails of its ravages, however, in 
the last centnry, are not well known, for the deaths by 
scarlet fever are mixed np in the old liills of mortality 
with measles and quinsy. Still the uuited nnuiber was 
small, and bears no couiparison with the results of recent 
observation. The amount of mortality occasioned bv 
scarlet fever tlirougbout England at the present time 
is really appalling. Mr. Farr, in his tliird and fourth 
Reports, has given a most instructive series of tables 
showing the deaths by scarlet fever (in each of the 324 
districts into which England and Wales have beea 
subdivided) for three years and a half, divided into 
fourteen quarterly periods, extending from July 1, 1837, 
to December 31, 1840. The general results of this 
gigantic investigation appear in the following brief 
summary : —

From this table we learn that the ravages of scarlet 
fever have (on the whole) progressively aagmented 
from the first to the last of these periods, and that the 
year 1840 exhibits an increase over 1837 of four to 
one. It further shows that the greatest mortality by 
scarlet fever takes place in the last three months of the 
year, and the smallest mortality in the months of April, 
May, and June. This is exactly what Dr. Willan had 
remarked nearly fifty years ago, when watching the 
visitations of epidemic scarlet fever in London. Never- 
theless, you will perceive that the influence of season 
on the mortality of scarlet fever is not very striking. 

[An examination of the months in which 4334 deaths by scarlet fever 
took place in New York, within sixty quarterly periods, during the fifteen 
years from 1830 to 1844 inclusive, shows that Hy far the greatest num- 
ber of deaths occurred during the months of January, February, and 
March, and the smallest number during the months of July, August, 
and September, the numbers corresponding with these ]>eriod8 
respectively being 1600 and 665 ; the numbers during the quarterly 
periods of October, November, and December, and of April, May, and 
June, being respectively 1084 and 986.] 

You are not to suppose that the above table exhibits 
a picture of the average mortality in England by this 
disease. The years 1838, '39, and '40 were years of

epidemic prevaleuce. It is probable that no epidemic 
of similar length and intensity ever before visited this 
country. It began in the metropolis in September, 

1838, and reached its acme with us early in December, 

1839. In the first week of that month, eighty-two per- 
sons died of scarlet fever in London, being a daily 
destruction of twelve lives. Nine hundred and seven- 
teen persons perished in London by scarlatina during 
the last quarter of 1839. In the whole year the deaths 
were 2500, being four times as many as died of small 
pox, and one-fifth more than the mortality by measles. 

[In New York, the wbolo number of deaths ty scarlet fever from 
1815 to 1828 inclusive, was only 97. while in the succeeding 21 years 
(from 1839 U> 1S4D inclusive) G17D fell victims to iL In Pljiladelphia, 
the number of deaths by it was comparatively smiiU from 1807 to 1831, 
in which year 200 are recorded, and in the fallowing year 307, the 
former sum enceeding by nearly fifty the whole morlality for the 24 
preceding years. It began U> prevail extensively in Boston also to 
1831, and has caused a targe number of deaths from that time to tho 
present.] 

The following are the observations of authors on the 
proportion which severe cases bear to the mild — inflam- 
matory, to the putrid. Dr. Willan states that in 17SG, 
he saw 39 cases of mahgnant to 152 of the anginose 
variety (one to four). Dr. Clark, of Newcastle, had 33 
cases of malignant to 73 of angiuose (one to two); 
and 23 out of 131 (or one in six) had dropsy superven- 
ing, lie adds — " Considering the numbers that are 
attacked in too mild a form to seek medical advice, the 
proportion of malignant to mild cases should not be 
rated higher than one in twenty." 

With reference to tlie per centage of morlality. we 
have sufficient materials for forming a good judgment. 
We lay aside Sir Gilbert Blane's experience, as apply-

ing ody to picked cases. At Ackworth school, in 
1803, the disease proved £sital at the rate of four per 
cent Dr. Tweedie informs as that out of 644 cases 
treated at the London Fever Hospital, in the twelve 
years between 1822 and 1833, there died thirty-eight 
(thirteen males and twenty-five females), which is 
nearly six per cent The rate of mortality at that hos- 
pital varies very greatly, far more than is observed in 
small pox. In 1832, it was as low as one in forty ; in 
1829, as high as one in six — an immense fluctnation, 
extending fi*om two and a half to seventeen per cent 

I am indebted to Mr. Ward, of Bodmin, for the fol- 
lowing : —

The average of these observations gives six per cent 
as the medium rate of mortality by scarlet fever. What 
a picture may be thence drawn of the actual extent of 
scarlet fever in years of epidemic prevalence ! It shows 
that in London, in 1839, there were 41,650 cases of 
this disease ; while throughout England and Wales, in 
1840, when 19,816 persons died, the total number of 
seizures must have reached the almost incredible num- 
ber of 330,266. 



PER CE^TAGE OF MORTALITY. 



There arc no statistical records to leach us (as in 
stnall pox) the period of greatest danger ; death has 
been said to take place in nine hours. I never saw 
anything so rapid as this ; biit I have seen death occur 
on the second day, and frequently ou the third. I 
would call sixty hours from the breaking out of the 
rash, the period of greatest danger Many, of course, 
die at a much later period, — on the eighth or twelfth 
day. Dropsy aud abdominal complications may pro- 
tract the date of death to a month. 

The proportion of fatal cases occurring at the several 
periods of life (young, adidt, and aged) is well illus- 
trated in the registrar general's tables. Out of 345 
cases proving fatal in London during the months of 
January and February, 3840, 3'26 were children (under 
fifteen), and only nineteen were adults. Out of "2014 
cases recorded by Mr. Farr in his fourth Report, '2419 
were children, 182 adults, and 13 aged persons. The 
violence of the disease falls therefore on children, as 
compared witli grown persons, in the proportion of 
seventeen to one in ihe first case — of twelve to one in 
the second.

Tlus table shows a remarkable uniformity in the age at which death 
took place by this disease in these diflferent places. {Proceed, of PhUoi. 
Soc, of OloBgoWy extracted by Amer, Jour, Med. Set., Apr. 1845.) 

It will be seen by the preceding tables, that but a fraction of the 
mortality by scarlet fever occurs over 40 years of age, almost one half of 
the deaths taking place between 2 and 5 years of age, although a few 
are recorded between 50 and 60, and one in this city between 60 and 
70 years. Sir Gilbert Blane saw but one case in a patient over 40 
years of age, and Dr. Copland has seen but one between 50 and 60 
years. Dr. C. Lees had one patient 70 years old with it, and Dr. 
Chapman had one 80 years old. It is also comparatively rare in the 
earliest months of life. 

In some epidemics, the disease is almost confined to patients between 
15 and 25 years of age. 

Scarlet fever would seem to be about six times less fatal among blacks 
in New York than among whites, the nuinber of deaths in proportion 
to the population of the two races, during the eight years from 1837 to 
1844 inclusive, being that of 1 to 70 of the whites, and of 1 to 450 of 
the blacks. In the year 1837, there were only 3 deaths by this disease 
among blacks to 570 among whites. Reference to the note on page 
35 will show that the mortality by scarlet fever was also much less 
among the blacks in Charleston (S.C.) than among the whites, though 
the disparity is much less than in New York.] 

Dr. Withering distinctly states, and certainly a gene- 



DIAGNOSIS OF SCARLATINA PROM UBASLES. 



ral iinpressioa prevails, that scarlaitoa invading adults 
is, cteferis paribus, a severer disease, and occasions a 
greater per centage of mortality, tlian %vlien it invades 
infantile life. Whether this he the fact or not, I have 
at present no means of jndging ; but for a long time it 
lias been known that scarlet fever is peculiarly danger- 
ous wlien it occurs at the puerperal period. The cir- 
cumstances in which the system is then placed suffi- 
ciently account for the fact: iho beat of ibe body — the 
exertion — the consequent exhanstion; and possibly the 
peculiar condition of the blood accompanying the puer- 
peral state. AH these things naturally tend to augment 
the virulence of fever, whether specific or non-specific, 
originating at that period. 

I shall not detain you wilh any remarks on prognosis. 
After the exposition I gave of tbc character of the 
symptoms in ibe anginose and malignant forms of scar- 
latina, you cannot fail to perceive both the signs and 
the causes of danger. 

When treating of measles, I mentioned briefly the 
chief points of diagnosis between it and scarlet fever, I 
will now recur, somewhat more in detail, to this subject, 
which, by ibe way, is very ably treated in Dr. Williams's 
work on the morbid poisons. 

1. Measles and scarlet fever differ in their incubative 
periods ; scarlet fever Hes latent one week — measles, 
two weeks, 

2. Measles and scarlet fever differ in the periods of 
their eruptive fever. Scarlet fever developes rasli in 
twenty-four hours, measles in seventy-two hours, after 
tlie setting in of fever. 

3. The two diseases differ in the color and aspect of 
the efflorescence. In scarlatina it is brigbl sc'arlet ; in 



180 PATHOLOGY OF SCARLATINA. 

measles, it is a dull raspberry red. In scarlatina, the 
eruption is extensive and diffused, brightest on parts 
covered. In measles, it is in patches, brightest on parts 
exposed. 

4. The diseases differ in the concomitant affection 
of the mucous tissues In scarlatina, there is early and 
often serious inflammation and sloughing of the throat 
In measles, the mucous affection is chiefly in the nose, 
eyes, and larynx. There is no disposition to cynanche 
or its consequences. 

5. The two diseases differ in their secondary actions. 
Scarlet fever is accompanied and followed by phrenitis 
and dropsy ; measles, by pneumonia. 

6. The two diseases differ, lastly, in their tolerance of 
remedies ; measles bears blood-letting well, scarlet fever 
badly. 

[In addition to the diagnostic marks mentioned by our author, majr 
be mentioned : 

1. Swelling of ih£ hands and sometimes of the feet, never present in 
mejisles, and hence of some importance as an external mark. 

2. Character of the desquamation — being in scarlatina in the form 
of flakes of greater or less size, and especially on the hands, from which 
the epidermis sometimes comes off like the fingers of a glove ; while in 
measles it is fine and branny. This point of difference is sometimes of 
importance on account of the sequelae of the two diseases.] 

I come next to investigate the pathology of scarla- 
tina ; to explain to you the laws which govern the 
phenomena of the disease — its rise — its symptoms — its 
varieties — its complications. The subject is one of great 
extent and intricacy, but it is one also of much patholo- 
gical interest, and of some practical importance. 

The notion that scarlet fever was the result of a mor- 
bid poison was one of very early growth. Morton 



FATHOLOQT OF SCARLATINA. 



181 



expresses very clearly and pithily the opinions enter- 
tained during the 17tli century on this subject: — " The , 
proximate cause of scarlatina," says he, "is a 2>oison 
defiling the animal spirits, whose malignity does not 
only overwhelm the spirits in its first attack, but by 
agitating the mass of blood, breaks it down into an acrid 
collnvies more en ergeiically than any other ferment." 

Navier (a French author), who has given the history 
of the epidemic of 1753, goes a step further, and attempts 
to connect this poison with that which occasions the 
distemper of horned cattle — a distemper which prevailed 
in London in 1839, and which has lately devastated 
Egypt. " In this bovine epizootic," says Navier, " the 
convalescent beasts lose their hair, and their skin peels 
off. When they die, the viscera are always found 
more or less in a gangrenous state." He gives it as his 
opinion that the contagion of scarlet fever originated 
with cattle, and was by them communicated to man. 
He traces also some connexion between these com- 
plaints and small pox, 1 menliou these circumstances 
because tiiey prove to yon how early liie attention of 
men's minds was directed to the analogy between the 
diseases of men and cattle, a doctrine uhich, investi- 
gated by the genius of Jenner, led afterwards to such 
brilliant results. 

Scarlatina is peculiarly the disease of temperate 
climates. It is comparatively rare in Bengal. Dr. 
Jackson, formerly of Calcutta, now of Chatham, informs 
me, that he cannot recall to mind having sceu any cases 
in India deserving the name of scarlatina. I have 
never met with any account of the disease as it occurs 
in the black skin ; but perhaps this may be my owa 
fault. 



182 LAWS OF 8CARLATI1IAL MIASM. 

[The lud afibrded by tint is lost in tho diagno«is of scarlet fever in 
blacks, but the characteristic distribution is still presenred, and the [mrts 
which are the seat of the eruption are marked by a deeper shade of the 
color of the skin, whether that be of a deep black, or of some its modifi- 
cations. Tlie precursory and accompanying symptoms, however, we 
most to be depended upon for diagnosis in this race.] 

America did not receive the contagion of scarlatina 
till the year 1 735, as we learn from a curious paper by 
CadwaUader Golden, Esq.* Its progress over that 
^at continent was singularly slow, but attended with 
great loss of life. ** Like most new diseases," says Mr. 
Kearsley, describing the epidemic that began in I7469 
*' it baffled every attempt to check its progress. Villages 
were depopulated by it, and parents left to bewail the 
loss of all their children." 

[The first appearance of scarlet fever in New England was in May, 
1736, at Kingston, an inland town about 50 miles eastward of Boston. 
On the 20th of August of the same year it appeared in Boston, and of 
about 4000 persons who had it, about 1 in 35 died. In the country 
towns the mortality was much greater, from 1 in 6 to 1 in 3 dying of 
it. In Kingston, where tho usual annual mortality was not above 9 or 
10, it rose that year to 102. ITie disease as it prevailed in New 
England in 1735 and '36, was described by Dr. William Doughu^, in a 
work published in 1736, and reprinted in the New England Journal of 
Medicine and Surgery^ vol. xiv. p. 1. For an analysis of his work, see 
Historical Sketch of State of Medicine, Ac, by John B. Beck, M. D., 
Transac, Med, Soc, State New York, Feb., 1850.] 

Scarlet fever affects the sexes in equal proportions, 
and very remarkably. In 1838 it deslroyed, in London, 
747 males, 777 females. In 1839, 1241 males, 1268 
females. Throughout England and Wales, in 1840 
(exclusive of die metropolis), 8927 males, 8935 fe- 
males !

LAWS OP BCAaLATINAL MUBH. 



[Of 2iiU deaths by scnrlet fever in New York, (iurins; tlio eight 
yearefrom 183T to 1844 inclusive, 1337 were ninlea and 12TT femnlea; 
and of 1074 JeHtiis hy llie tiiime disease in Philiidelpliia, during the 
nine yesra from 1837 to I8i5 inclusive, 1008 were males, wiJ 968 
females.] 

The infecting distance of the miasm has not heen 
investigated; but It is found that when it invades a 
school, no precautions avail anj-thing towards prevent- 
ing the spread of tlie infection. This has often been 
proved at ilie London Foundhng Hospital. At Ack- 
worth, in 1803, the contagion hiigered in the school for 
four months, in spite of every effort. With regard to 
the susceptibility of this complaint. Dr. Bintis tells us, 
that out of 216 scholars at Ackworth school, 184 were 
affected. Dr. .Adams remarks that this is a larger pro- 
portion than is commonly found susceptible in districts 
or families. Like all other miasms, that of scarlet fever 
is capable of attachment to fomitcs, especially clothes. 

[The question is stili unsetlleU bolb la to the exact period at which a 
jMtJenl with scarlet fever liegins U> ba ti fucus of cutitogion, and also 
how loug he eontinuea to net as such by the secretion of the poison. 

"With regard to the first point. Dr. Robert Williams {o» l^orbiil Poi- 
wm) thought that the generatioa of the poison commences with the 
fever, and before the appearance of the eruption. With regard to the 
MOOnd, it WHS the opinion of l)r. Willan, that children convalescing fr>]ni 
this disease, notwithstanding every attention to cleanliness and change 
of apparel, are cnpnble of communicating it (especially to other children) 
for two or three weeks after apparent recovery. 

We have always been led to consider the end of the periwl of desqua- 
nalion a» the time when the patient ceases to senerale the poison, and 
to commuiiicale it directly by eirianntion tmm his own {lerson. All 
com mu mention after tlint period we sliould be inclined to refer to 
Ibmites, of the communication of the diseagc by which means at inter- 
Tsla of even several months, and at considerable distances, numeroos 
KDstences arc on record.] 

No doubt exists that, in a very large proportion of 



184 RBOURRENCE OF BOARLATIlfA.* 

cases, scarlet fever is the produce of a specific miasm ; 
but the qaestion may well arise, whether any combina- 
tion of circumstances can developean eruption possessing 
the characters of scarlatina. I am bound to tell yon 
that I believe they can. I have seen scarlet eruption, 
in no respect different from that of ordinary miasmatic 
scarlatina, arising from exposure to cold and moisture. 
A young man residing near St James's Street, some 
years since went down to the Serpentine to bathe. He 
walked in a hurry, plunged in when overheated, and 
two days afterwards I saw him covered with scarlet 
eruption. He had suffered in the same way once before. 
I often see true scarlatinal eruption occurring in the 
progress of the secondary fever of small pox, without 
any grounds for believing that contagion had operated. 
It seems as if secondary fever can develope this eruption 
in the same way as it throws out erysipelas. 

[We slioiild ourselves prefer the application of the term erytliematous 
or roseolar, rather than " scarlatinal," to the efflorescence in the preceding 
case, as well as to that sometimes occurrim; in the secondary fever of 
small pox, produced as the former was by a sudden check of perspiration, 
and belonging, as it does, to analogous forms of eruption produced by 
connrnm causes of disease — restricting the use of the term scarlatinal to 
that form of eruption constituting one of the characteristics of a febrile 
exantliem, which originates in contagion, is governed by fixed laws, 
pursues a definite course, is liable to certain complications and sequelae, 
ike. We should fear lest the use of the ej)ithet scarlatinal in a generic 
sense, to signify different kinds of redness, non-specific as well as specific, 
however close the resemblance between them, would tend rather to add 
to the confusion already too great, which hangs about the nomenclature 
of cutaneous diseases.] 

Thus much I thought it right to say before approach- 
ing the vexata questio of secondary attacks of scarlet 
fever. Observe the conflicting statements of authors on 



Kecurrekce of scarlatina. 



186 



this licatl. Dr. V/ilhn (ctTtaiiily one ot" tbt; most Hcute 
and careful observers of die disease) sajs, tliiit out of 
2000 cases which be atteaded. he saw no ioslance of 
recurrence. Dr. Carrie, of Liverpool, who devoted 
much alteution to scarlatina, was compelled, by the 
results of long experience, to " reuoiince the opinion he 
had early imbibed, and to confess that the same indivi- 
dual is liable to scarlatina once only," Sir Gilbert 
Blane, on the other baud, met with one instance of 
scarlet fever occurring thrice, and, as be says. " without 
the least suspicion of ambiguity." Dr. Binns inclines 
to the notion of occasional recurrence. 

Exceptions do occur; ncvcribeless, the law of ex- 
hausted susceptibility, as Dr. Williams calls it, is very 
strongly marked iu tbis disease. I cannot doubt hut 
that a large number of the alleged cases of recurrent 
scarlet fever are cases of licbcnous or iirticarial eruption, 
suddenly brought on by cold, or some deleterious article 
of food — cases which have no decided iuculiative stage, 
which run a premature cour.se, wholly distinct from the 
steady march of a specific anginose fever. Medicine is 
filled to overflowing wuh false facts of this kind, set

my youngest son was born, evidently saffering under 
some form of fever. The throat was affected on the 
following day, obviously from angina maligna. Erup- 
tion was never developed. The child drooped, and 
died on the first of May. 

Attempts have been made to produce scarlet fever 
artificially by inoculating with the blood, or with the 
serum of miliary vesicles intermixed with the specifks 
eruption. We are informed that scarlet fever, unmiti- 
gated, was subsequently developed. No good could 
have been anticipated from such a measure. 

You see the great diversities in the aspect of scarlet 
fever. Can any explanation of this phenomenon be 
offered which is at all satisfactory t Is it attributable 
to the weather, to diversities of individual habit, to di- 
versities in the quality of the contagious miasm t Sta- 
tistics teach us that season has nothing to do with it 
The year 1839 was peculiarly fine, yet in that year 
scarlet fever raged in London like a pestilence. I am 
well aware that bad cases sometimes propagate mild 
cases, and vice versa ; but I cannot shut my eyes to the 
fact, that, on a large scale, you will find mild cases suc- 
ceeding each other, and severe cases producing severe 
cases. I am inclined, therefore, to attribute something 
to the quality of the infective miasm ; but I candidly 
acknowledge the obscurity in which this branch of 
exanthematic pathology is involved, and hope, with 
Huxham, it may hereafter be cleared up. 

The management of scarlet fever, in all its varied 
forms, now demands your best attention. Let us first 
consider the objects which should be kept in view. 1. 
It is your duty to moderate arterial excitement when it

runs tiaugeroiisl)' high, and especially to lessen llie licat 
of tlie surface, 2. You must support tlie tone of the 
system, when oppressed or subdued by the malignity of 
the poison. 3. You must obviate local congestions and 
the organic complications which arise in the progress of 
the fever. In ihese general propositions, all physicians 
will probably agree; but the difficulty consists in prac- 
tically carrying them out. What are the best means of 
(iiltilliiig these indications 1 How far are the remedies 
to he pushed ! These are the pinching questions. Our 
chief reliance, in the management of scarlet fever, is 
placed in the skilful use of one or more of the fidlowiug 
classes of remedies : — 1. Emetics; 2. cold afrusiiin; 3. 
blood-letting, general and topical; 4. purgatives; 5. 
ionics, stimulants, and antiseptics. They will require 
separate invesiigation. 

We may begin, however, by getting rid of ihe mild 
form of scarlatina, which, as Sydenham said, demands 
very litde aid from the physician. The cases should be 
watched, lest local congestions arise; but otherwise, a 
gentle laxative powder, and abstinence from meat and 
beer, are alone required. We may, in the same sum- 
mary way, dispatch those cases which are at the other 
extremity of the chain — the cases of angina maligna 
gangrenosa, with undeveloped eruption, which, from 
the very onset, are characterized by depression, or col- 
lapse of the nervous system. Common sense here 
dictates an early recourse to stimulatits — to wine, brandy, 
cordial draughts containing aether, camphor julep, aro- 
matic confection, and tincture of bark, in sncli quantities 
and doses as the stomach will bear, and the age of the 
patient justify. On this point there is no room for 
doubt or cavil. 



190 BLOOD-LETTING IN SCARLATINA. 

duced. Sanctioned by my uncle, the late Dr. Gregory 
of Edinburgli, this plan has been amply tried in all parts 
of the world, but it has not realized the expectations of 
its proposer. 

The truth is, that the cold affusion is applicable only 
to a small number of cases. It is adapted for young 
people with high anginose inflammation and a burning 
hot skin, without plethora, without depression of nervous 
energy ; but it is inapplicable to the scarlatina of adults, 
accompanied with coma, phrenitis, or marked debility. 
It is wholly unfit for cases of cynanche maligna. It 
answers its purpose very well for the first day or two, 
but it is often impossible to continue its use. Lastly, it 
seems to increase the disposition to dropsy. Dr. Currie 
proposed to obviate some of these objections by substi- 
tuting tepid sponging for the more formidable affusion^ 
but a palliative like this is little fitted to meet the exi- 
gencies of severe cases. Affusion was practised by 
stripping the patient and pouring over his naked body 
four or five gallons of the coldest water, repeating this 
process every two or three hours, until the fever was 
permanently subdued. 

I can recommend this practice to you, as being well 
adaj)ted to the scarlet fever of young persons of san- 
guine temperament, and tbe early stages of the disorder. 
Cold or tepid sponging with vinegar and water proves 
an useful auxiliary at all periods of the disease. It 
refresbes the patient, relieves headache, and lessens 
restlessness. 

3. Blood-letting, general and topical. Some physi- 
cians discourage all loss of blood in scarlatina, as being 
foreign to the genius of the disease. Others strongly 
advise it. Much will depend upon the character of the 



GENERAL AND TOPICAL. 



191 



symptoms, the period of tlio disease, the couJilioii of 
the paliciil ; t)Ut I wisli to impress upon you strongly, 
that scarlet fever not only aduiils of blood-letiing, but 
often imperatively reqnires il, and that on general bleed- 
ing- alone the safety of the patient often depends. Let 
me give you a few cases in illustration. 

Miss Ramsay (ietatis 12), in 1832, had scarlet fever. 
On the second day, slie becauie very sleepy. On the 
third day, this sleepiness was fast treading on the con- 
dition of coma. I had her liled in the jugnlar vein to 
twelve ounces, and all went on well. 

On Thursday, 22d June, 1837, my eldest son, then 
six years old, was seized with rigors and vomiting. On 
the following day. scarlet fever appeared in great in- 
leosity. The boy is of sanguine temperament, and had 
required venesection the preceding year for influenza. 
On the uiglit of Sunday, the 25tli, the febrile symptoms 
ran high ; all medicine was rejected hy the stomach. 
The long continuance of the vomiting indicated the 
extension of inllauimatory action to the mucous mem- 
brane uf the stomach, and probably also to the dia- 
phragm and neighboring structures. I bled him to six 
ounces with decided benefit, and feel persuaded that 
without the loss of blood, fever would soon have de- 
stroyed him. 

In 1840, Mrs, Sabine, of Hoxton, took scarlet fever 
during her confiuement, and narrowly e-scaped. Secon- 
dary fever ensued. Languor, failing appetite, and a 
general sense of malaise, continued long. She had 
been sent to Margate for change of air. On her return 
I saw her. and had her immediately bled to twelve 
otlDces, Her recovery then ■wont on progressively. 

While I thus advocate the necessity of blood-letting 



^mi 



192 BLOOD-LETTING. 

in certain cases, I freely acknowledge that it is inappli- 
cable to others. You would not always do harm by 
the attempt (for it is one thing in scarlet fever to open 
a vein, and another to draw blood), but any such indis* 
criminate use of the remedy would expose yon and the 
profession of physic to just reproach. The successful 
treatment of the disease by bleeding in one epidemic, 
at one season, and in one district, does not authorize 
the same procedure in another epidemic, a diflferent 
season, or a diflferent locality. Dr. Willan tells us, that 
in London, in 1785, the usual results of blood-letting 
were, great depression and faintness, the pulse becom- 
ing weak, frequent, and often irregular. Again, in the 
epidemic of 1733, at Edinburgh, we find it stated that 
but few died who were timely blooded. It was then 
remarked, what I have often noticed, that vomiting in 
this disease is only to be checked by venesection. 

The blood drawn in scarlet fever scarcely ever pre- 
sents a firm coagulum. In the majority of cases the 
blood coagulates rapidly into a soft jelly, showing the 
small power in the system, and rendering it probable 
that the urgent symptoms in scarlet fever (such as deli- 
rium and coma) depend more upon congested veins and 
stagnation in the capillaries, than upon arterial action. 
This pathological condition of the circulating system 
was not unknown to the old authors, one of whom 
remarked, that when the superficial vessels are dis- 
tended, there cannot he the same amount of blood in 
the interior as when the skin is cold. We may hence 
learn why fainting so often follows venesection in scar- 
latina, and why we scarcely ever bleed twice. Post- 
mortem examinations confirm this doctrine. Dr. Wells 
records the dissection of a young soldier who died of 



BLOOD-LETTING. 

scarlatina! coma, uoatteiided with any cousiderable 
affection of the throat. No marks of inflaminalion, or 
even of congestion, were discovered in the brain.* 

Local hlood-letting is well adapted to many cases of 
scarlet fever — to cases accompanied with great deter- 
mination of blood to the throat — to cases attended with 
headache, or threatening coma. I applied leeches to 
the temples of Mr. Dry, of Tottenham-conn-road, 
whose case was detailed in the last lecture. They 
lowered the pulse until it began to flutter alarmingly, 
but the progress of cerebral congestion was checked. 
In the management of the several inflammatory sequels 
of scarlatina (otitis, ophthalmia, and pneumonia), 
leeches and cupping are quite indispensable. 

Leeches generally bleed profusely in scarlatina, from 
the excited slate of the cutaneous circulation. Four 
leeches in scarlatina will often do as much as twelve in 
typhus. It becomes occasionally necessary to slop the 
bleeding, which lunar caustic will do effectually. This 
tendency of leech-bites is always to be kept in view, 
bat especially in the scarlet fever of young children. 
The child's life might otherwise be sacrificed, and the 
measure itself brought unfairly into disrepute. 

[It mny safely be said, that genernl bleeding in scarlet fever b the 
szoeption &nd oot the rule, at least in tbia country. That it may be

with great caution in the primary disease. In some of the seqadtti b 
certain cases, their good eflfect is more decided.] 

4. Purgative Medicines. Dr. Withering, who was 
so devoted to emetics, declared *'that the action of 
purgatives was altogether repugnant to the curative 
indications in this disease." On the other hand. Dr. 
Hamilton, of Edinburgh, devoted one chapter of his 
work on Purgative Medicines to the recommendation of 
purgatives. Withering^s prejudices have entirely passed 
away, and purgatives are now largely and most bene- 
ficially used in every stage of scarlatina anginosa, firom 
the first onset of fever to the close of the desquamation. 
I know of no objection whatever to their use, and am 
most confident of their great utility. 

The forms of purgative medicine that I would 
recommend to you are calomel and jalap — calomel and 
rhubarb — senna and salts — jalap with cream of tartar — 
senna with cream of tartar — castor oil, — and occasion- 
ally, the combination of calomel, James's powder, and 
extract of colocynth. 

I have often pushed calomel to a great extent both 
in adults and children, — not that I attach importance 
to any specific effect from the mercury, for I never 
saw it do good, except when it purged ; but because, 
in the burning heat of scarlatina, no purgative will act, 
unless aided by the relaxing qualities of calomel. No 
secretion can otherwise be obtained from the vessels 
of the liver and intestinal mucous surface ; and this, I 
need not tell you, is the whole secret and theory of 
purging. You must, of course, be cautious with your 
drastic purgatives, when there is a tendency to syncope. 

[PurgaUves are more sparingly used in this country, even in the

pnow form of scarlBt fover, as h the ease with blood-letting, as 
already remarked, than our author would seem to recommend, and 
aoiuu jiractitioners abstain faim them entirely, using only mild Idxatires 
or eccmata. There arc cases of the congestive farm, in «hich the 
prompt effect of an active cathartic i« f-ivorahlc, both by removing 
offending mBteriala from the bowels, and by ite revulsive effect ; but it 
ii rare that the esbibition, much li-sa the repetition of the active catliar- 
tics enumerated by our author, seems to be called for. At the same 
time, fluitable means should be umd to keep the bowtU sufficientljr 
open. 

Tlie use of calomel in this disease originated witli Dr. William 
Douglass in the severe epidemic in New England iu l73fi and 'S6, 
of which ho published an account already referred to. page 182. Forao 
analysis of his work, and account of the reasons which led him to the 
use of that remedy, aee a valuable paper on the '* State of Medicine in 
(lie American colonies from their lirsl settlement to the Revolution," by 
John B. Beck, M.D., published in the TraMtacl. of l/ie Mtd. Soc. of 
the StaU t^Neie York. Feb., 1850. 

Dr. Jacob Ogd<m, of Long Island, also used calomel extensively in 
tbis disease, and with success, about the year lT4f). (iVcui York Medi- 
tal Repository, vol. v. p. 97, quoted by Dr. Beck in above-mentioned 
[taper, and also in his Infant Thrrapeuties) 

Calomel has been more or less used in the treatment of scarlet fever 
uncc that time. Some practitioners continue lU use nt intervals during 
the whole of the disease, while others give it only at thu commencement 
«f the attack ag a purgative. For this purpose, and when tlie secretiom 
of the stomach and small intestines are disordered, it is often of great 
««rvice. In the formidable laryngeal complication of the disease, ita 
exhibition in small doses at short intervalx, with appropriate local means, 
should never be neglected.] 

5. StimulRnts aud cordlRls are iiiiproppr (except in 
rare cases) in the early stage, and wholly unfit for the 
inflammatory type of scarlatina. When, either hy the 
debility succeeding venesection, or the strong action of 
purgative medicine, or the depressing iuf]ueuce of (he 
poison, the pulse flags, the countenance turns pale, and 
the skin cools down, camphor, sether, the citrate of 
ammonia, and similar cordials, wllh wine, must be

given. The only stimulus that can be allowed at all 
times is that of an acid. Direct, therefore, a drachm of 
the diluted hydrochloric acid, with half an ounce of 
syrup of orange peel and eight ounces of water; and 
let the patient take an ounce and a half of such a mix- 
ture frequently. 

The occurrence of diarrhoea demands tlie employ- 
ment of gentle aromatics and astringents, such as the 
aromatic confection, chalk mixture, and laudanum. 
Arrow root with port wine must be given at the same 
time. In the truly sloughy and gangrenous forms of 
anginose scarlatina, a variety of medicines supposed to 
possess antiseptic properties have been extolled. In 
the West Indies, in 1787, they found an infusion of 
capsicum very serviceable. Dr. Peart recommends very 
strongly the carbonate of ammonia, but Dr. Tweedie's 
large experience docs not bear out the encomiums 
which he lavishes on the remedy. One great objection 
to its use is the difficulty of swallowing it — a difficulty, 
indeed, which meets us in every stage of scarlatina, and 
which authors are very little inclined to consider. 

]jark was at one time highly extolled as an antiseptic 
and tonic in scarlatina. It was even given when the 
** heat of the surface was sharp." A broken texture and 
putrid tendency of tluj blood were then considered valid 
reasons for giving bark. The practice is now seldom 
pursued, except as a last resource, when the throat is 
sloughy, with a small pulse, cold skin, and great nervous 
depression. Wine and brandy, however, are much 
preferable under such circumstances. 

You must not altogether neglect the local treatment 
of the angina. Gargles of rose infusion wash away 
the abundant and vitiated mucus of the throat, give to

it a clearer aspect, but do uo otiier good. When there 
b a breach of surface, acids give great pain. You may 
then use with advantage the decoction of bark with 
mel rossc, or Sauvages' once famous gargle, lime-water 
with houcy. As children cannot gargle, the nurse must 
be instructed to clear the throat by means of a camel's 
hair pencil dipped in a solution of currant jelly.

The inauagcment of the sequelae of scarlet fever 
next claims your attention. The cellular iniSamniation 
of the neck is to be treated by poultices in the first 
instance. As soon as possible, free incisions must be 
made through the skin, to allow of the escape of the 
sloughs, and of that imperfect pus which is all that the 
weakened state of the system pennits to be formed 
The strength to be supported, meantime, with beef-tea 
and wine. 

In that state of general and vascular debility which 
I have described as occasionally occurring as a sequence 
of scarlet fever, the tongue being clean, and the heart 
disposed to syncope, cordial draughts containing 
compound spirit of ammonia with camphor julep 
and tincture of lavender must be freely administered. 
Nourishment, too, must be frequently given with port 
wine. 

The dropsy which succeeds scarlatina deserves all 
your care and consideration. Dr. Wells was, I believe, 
the first to throw off the pathological trammels which 
connected this symptom with debility of the capillaries. 
He saw^ in it an inflammatory allbction ; he noticed its 
coincidence with a white tongue and a sharp pulse, 
and he knew the benefit of an antij)lilogistic treatment 
This doctrine is that now generally admitted. We 
consider the dropsy succeeding scarlatina as depending 
on arterial excitement, either general or local, which 
must be subdued, by mild means if possible, but failing

them (or in the event of great urgenc)'', even iu the first 
instance), by blood-letting. 

Dropsy seldom occurs early in the secondary fever of 
scarlatina, It is almost always preceded hy symptoms 
which will warn you of its approach, when your eyes 
are opened to the pathology of exanthematic sequelae. 
In the larger proportion of cases, you will succeed in 
relieving the dropsy effectuaHy. Plenck, however, a 
celebrated physician of Vienna in the last century, 
who wrote on eruptive fevers (1762), held that the 
danger was even greater from the dropsy than the fever 
itself. 

I cannot doubt but that a large proportion of cases 
of scarlatinal dropsy arise from the neglect of measures 
which ought to have been adopted iu an earlier stage 
of the disease. If a certain amount of hlood-leltiug, a 
certain number of doses of calomel and jalap, a certain 
amount of rest and abstinence had been indicated, but 
neglected or withheld, then, when dropsy occurs, the 
deficiency must be made up. The same things must 
be done late, which ought to have been done early. 
In all cases, it is your duty to watch carefully the 
decline of scarlet fever. If the pulse, tongue, and secre- 
tions be not satisfactory, exhibit daily, or on alternate 
days, a purgative draught, containing infusion of senna, 
cream of tartar, and tincture of jalap, so as to insure 
two motions ; direct, at the same time, a diureiic julep, 
containiug acetate of potash, tincture of digitalis, and 
the spirit, setheris nitrici, or some equivalent promoter 
of renal activity, in mint water. If these measures do 
not meet the exigencies of the case, if the character of 
die urine, and of the pulse and tongue, indicate increas- 
ing or unabated disorder, take ten or twelve ounces of 



MANAGEHBHT OF THE DBOPSY. 

blood froui llie arm. Do not wait for the appearance 
of dropsical swellings to adopt this proceeding, for by 
sucli delay further mischief will ensue, Coagalable 
lymph will be effused on some of the great serous sur- 
faces, or in the interior of the heart. I need not say 
bow immeasurably this would add to the severity of the 
dropsy and the danger of the patient. 

Tonics are not to be entirely ihrown aside in the 
management of scarlatinal dropsy. You will meet with 
cases that give countenance to the doctrine that the 
exhalant vessels want tone, that blood is detained in 
the cutaneous capillaries for want of sufiScient energy to 
restore it back to the heart. Such cases will necessa- 
rily carry with them other evidences of this condition 
of the system, called by pathologists kucopklegmagia, or 
white inflammation. You will find the countenance 
sallow, the pulse feeble, the tongue clean (perhaps mor- 
bidly red), and the urine, though scanty, yet pa!e. 
Under such circumstances, you would be justified in 
giving, and expecting benefit from, stimulants, in com- 
bination witli diuretics. The infusion of cascarilla, 
mixed with tincture of capsicum, compound spirits of 
juniper, the spirit of nitric aether, a few drops of tinctore 
of digitahs, and some syrup of ginger, will supply yon 
with an old-fashioned, but not the less serviceable 
combination. 

The compound squill pill, with a due proportion of 
pilula hydrargyri, may be given night and niornbg, so 
as to insure the activity of the kidney. 

Measures such as these will sufficiently relieve a very 
large proportion of the cases of scarlatinal dropsy which 
you will meet with, but some wiU prove rebellious to 
all your care, probably from the serious injury done to

the lungs, liver, or heart, in the first days of the disor- 
der. My earnest advice to you, therefore, is to try aod 
prevent tJie secondary dropsy rather than to display 
your skill by curing it when it has arisen. 

[For lurtber remarks ( 
fuvtr, see Appendix I.] 

Convulsions occurring during the secondary fever of 
scarlatina demand the loss of blood cither from the arm 
or by leeches, according to the age and strength of the 
patient, with active purgatives containitig calomel, and 
the application of cold spirituous lotions to the head 
and precordial region. 

[Dr. Marshall Hull ruhiles u coso of itcuto anasarca and convuUJons in 
a boj, twelve years old, cured by venesection, fuUowed by leeches, 
with purgatives, cold to the bead, pediluvia, dsc, and eays he oonsiders 
that, in euch cnses, the remedy is blood-Utting, until relief and ueuritg

Londnn Laneei.) 

At a meeting of the Royiil Med. Chir. Soc. (London) in Feb., 1847, 
Dr. Rogers remarked [hat he had seen two cAies of scarlatinal convnl- 
B10IW, wliieh dime on after the twenty-first day of th^ diBt^aae — both 
patients having suffered from dropsy with albuminnria. In one oa«e, 
he used dry cuj)ping over the loins ; in the other, at the nape of the 
neck — both recovered. 

Without entering further into the particulan of the trontm^Dt of 
tcarlet fever, either generally or locally, we will add a few propositione 
which we think worthy of remembrance, and the truth of which will 
probably not be questioned : 

1. It is a telf-limiUd disease, and nature is oflcn entirely competent 
to conduct our patient safely through it. 

2. It presents every variety as to tyjie and mode of attack, and every 
degree as to severity, and hence we must prescribe for the svniptomB, 
and not for tliu name of the disease. 

3. Ataxic symptoms and local determinatjuns arc those which most 
frequently require the interference of art. 

4. The poison of the miasm is of a most depressing nature, and

henoe great caution is required in the use of meant which tend to 
exhaust the vital powers. 

6. The iequila of the disease are often much more formidable than 
the difleaae itself, and must always be carefully watched for and guarded 
against^ depending, as thej often do, upon the management of the case 
in itB earlier stages. 

6. Tlie nature of the prevailing epidemic should always be carefully 
studied, both in the management of our own cases at any particular 
time, and in judging of the treatment of recorded cases ; for the history 
of diflferent epidemics, both in this country and abroad, proves conclu- 
sively that the most opposite means have been equally successful at 
diftrent times, and in different places.

Erysipelas, called also the rose, ignis sacer, and St^J 
Anthony's fire, is an exanthema, and therefore properly 1 
falls to be disctissed in this division of the course ; but 1 
we shall find its pathology to be in many points differ- I 
eat from that of the thrte diseases already treated of! 1 
It is, ill fad, the link which connects the purely zymotic i 
exautheiiiala with those diseases of the human body 
which originate from internal causes, and are uncon- 
nected with specific miasm. Erysipelas is a disease of | 
which the pathological hearings, long as it has been i 
known, are only now beginning to be well understood. 
It is a disease which, from ils occasional severity, as 
well as on account of its frequency, merits your best 
attention. 

Little need be said, regarding the literary liistory of 1 
erysipelas. It was well known to the Greeks and f 
Romans, and we retain the name which Hippocrates j 
and the Greek pliysicians originally gave it. Two ;

derivadons of the word erysipelas are proposed, both 
supported by high classical authority; some derive it 
from the two Greek words spt^po^, red, and csXXo^, livid 
— ^livid redness. The German lexicographers sanction 
this derivation. Almost all the English authorities 
(including Donnegan) derive the word from cpuu, to draw 
forth, and ctXa^, near ; expressive, it is said, of the ten- 
dency of the disorder to spread or extend itself to 
neighboring parts, in contradistinction to those forms 
of inflammation called by the Greeks apostatic (a<o and 
itfniiu) and metastatic, from their more fixed nature. I 
give yon your choice of the two derivations, premising 
that I prefer the first 

The term St Anthon/s fire was first applied to this 
disease in the dark ages of literature, when all the little 
physic that was known was monopolized by monks and 
ecclesiastics, who, in cases of difiiculty, naturally sought 
aid in prayer and invocation. Diseases came thus to be 
consigned to one or other of the many saints in the 
Romish calendar. The intercession of St Nicasius 
was implored in small pox. St Vitus's shrine was 
sought by those who labored under chorea. Erysipelas 
had for its patron St Anthony. The circumstances 
which led to this selection are not unknown. In 1087, 
a pestilential erysipelas, or sacred fire, ravaged the inte- 
rior of France, and especially the district of Dauphine. 
Now it so happened, that two years previous to this 
epidemic, the bones and reUcs of St Anthony had been 
brought from Constantinople by the pious care of 
Joselin, a nobleman of that country, and deposited in 
the church of a Benedictine priory, in the neighborhood 
of Vienne. Numbers of pilgrims flocked tliither, and 
many miraculous cures were there performed. This

success fixed St. Anthony in the perpetual patronage 
of erysipelas. 

We may gather something from the simple fact ihal 
erjsipelas was known to and well described by Hippo- 
crates. It shows us that physicians who could so dis- 
tinguish erysipelas would not have failed to describe 
with equal accuracy, and to name with equal judgment, 
small pox, measles, and scarlet fever, had those diseases 
existed in tlieir days. Their not doing so is proof 
positive that such diseases did not then exist. It shows, 
farther, that there must be something very different in 
the great pathological features of erysipelas from those 
of the three greater exanthemata ; else how did it hap- 
pen tlial erysipelas should have been known to them, 
and not (he three others 1 

It will conduce to a clearer understanding of erysipelas, 
if, in treaiing of it, I reverse the order in which 1 have 
hitlierto investigated the eruptive fevers. I shall here 
first explain to you the pathology of erysipelas, I shall 
attempt to show you In what respects it diSers from the 
other exanthemata, under what circumstances it origin- 
ates, and what explanation of its various sources has 
been offered by ancient as well as by modern authors. 
Having thus discussed the subject of erysipelas theoreti- 
cally, we shall be better prepared for the iuvestigation 
of its appearances, its progress, its terminations, its sta- 
tistics, and, lastly, its methbd of treatment. 

I must begin by informing yon, that by the term 
erysipelas we mean an infiammatlon of the skin, and 
very commonly, also, of tlie subjacent cellular texture ; 
often preceded, and almost invariably accompanied, by 
fever. Such a disorder originates from various causes. 
Its course and duration are alike variable. So far from 



206 CAUSES OF ERYSIPELAS. 

the constitutional susceptibility (as in the case of the 
three greater exanthemata) being exhausted by one 
attack of erysipelas, the disposition to the disease seems 
often, as life advances, to augment with each successive 
seizure. 

I shall have occasion to notice great diversities of 
opinion among authors upon almost every topic which 
tlie pathology of erysipelas involves. Nosologists differ 
as to its true situation, whether among the exanthemata 
or the phlegmasiac. There are strange contradictions 
in the statements of authors regarding the mode of its 
propagation, and still wider differences of opinion in 
respect of the best method of treating the disease. 

With regard to nosology, we have outlived that idle 
display of learning which made it an object of impor- 
tance to what class or order any particular disease was 
to be assigned. We consider it here as an exanthema, 
following in this respect the footsteps of Dr. Cullcn ; 
but 1 beg you clearly to understand, that very good 
reasons might be advanced why it should be transferred 
to the phlegmasisc. The matter, however, is not wortli 
wasting time about. 

With respect to the causes of erysipelas, however, 
and the manner in which it spreads, the diversities of 
opinion are of infinitely more importance ; and these 
must now be carefully hivestigated. 

In ancient times, by Hippocrates, and the followers 
of the Hippocratic or humoral patholog}-, erysipelas was 
held to be a disease originating from some intestine 
commotion of the humors, which threw off, or elimi- 
nated, the peccant matter by means of the skin. ' This 
doctrine continued, with very slight change of j)hrase- 
ology, to be generally received by pathologists until a 



OPINION or DR. WELLS. 



comparatively recent period. Dr. Ciiilen says, '■ I con- 
sider the erysipelas to depend on a mailer generated 
within the body, and which, analogous to the other 
cases of e.\aiithema, is, in consequence o(" fever, thrown 
out upon the surface of the body," He admits a spe- 
cies of erysipelas (or rather, erytiiema) arising from an 
external cause, capable of throwing off contagious ema- 
nations, but he makes no meQtion of any morbid poison 
or miasm primarily giving rise to iL His words are — 
" This disease is not commonly contagious, but as it 
may arise from an acrid matter externally applied, so It 
is possible that the disease may sometimes he commu- 
nicated from one person to another." 

The modern notions of the nature, and sources, and 
pathological relations of erysipelas, have made con- 
siderable advances since the days of Cullen (now more 
than half a century ago), I know no author who has 
laid them down fully, but Dr. Williams, in his valuable 
work "On the Morbid Poisons," 

The first inroad upon the old notions concerning 
erysipelas was made by Dr. Wells, formerly physician of 
tliis hospital, who, in 1798, published some statements 
showing the contagiousness of erysipelas. These facts, 
and the opinion founded on them, were long neglected ; 
but of late years they have been forced upon the atten- 
tion of pathologists, Iiy the undeniable evidence of the 
frequent spreading of erysipelas in hospitals, and the 
difficulty of explaining that circumstance on any oiher 
principle than that of the generation of erysipelas by a 
morbid poison, or miasm. 

I propose, first, to state to you the facts which prove 
erysipelas to be an epidemic malady, and which, satis- 
factorily to my mind, show that its most important 



208 MIASMATIC ORIGIN OF ERYSIPELAS. 

source is miasmatic. I shall then tell you on what 
grounds we further maintain that this miasm, when 
formed, is capable of propagating itself by contagious 
emanations. Lastly, it will be my duty to explain to 
you iiow erysipelas originates occasionally from causes 
not of a specific nature, some of which are internal, 
others external to the human frame. 

Sauvages, in his " Nosologia Metliodica," pubUshed 
soon after his death (which took place in 1767), admits 
an erysipelas contagiosum, but on what turns out to be 
most doubtful authority, for the epidemic referred to by 
him in support of that opinion (that of Toulouse, in 
1715) was scarlatina, not erysipelas : in fact, we cannot 
detect any trace of the doctrine of iniasmatic erysipelas 
prior to the year 1760. In the summer of that year, a 
person laboring under eri/sijte/as of the face was brought 
into this very hospital, where he died. Another patient, 
having a diflerent disease, w^as put into the same bed 
before it was duly purified. This patient was shortly 
after seized with erysipelas of the face. Several other 
persons in the hospital were then attacked, among whom 
was an upper nurse, or sister, and she died. A rumor 
hence arose that the plague had got into the hospital ; 
and so widely did this opinion spread, that an adver- 
tisement was inserted in the newspapers of the day, 
contradicting the rumor. This, you will observe, is an 
instance of erysipelas brought into a hospital, and there 
propagating itself. I am not able to tell you who first 
noticed the fact that erysipelas will comvience in a 
hospital, without any suspicion of importation. Dr. 
Baillie informs us that during the years 1795 and 1796, 
erysipelas < f the face was much more frequent at St. 



MIASUATIC ORIGIN OF ERYSIPELAS. 209 

George's Hospital tban he had ever before knowD it to 
be. Many persons, he says, were attacked by tliis dis- 
ease after they came to the hospital: and as the cases 
in a particular ward were more numerous than in any 
other, Dr. Baillie was led tp suspect that the disorder 
was contagions. He is silent, however, on the subject 
of origin ; and we are unable to say whether this erysi- 
pelas was originally bred in the hospital, or imported, 
and afterwards propagated by contagion. 

M. C'almiei, writing in 1828, says, " there are years 
when in the hospitals for the insane in Paris, erysipelas 
is almost indefinitely multiplied; so that it is necessary 
to suspend all treatment by counter-irritants (setons, 
moxas, and blisters), because tliey are almost certainly 
followed by erysipelas. Even the opening of a vein, or 
the appUcation of leeches, is followed by a like result. 
We may be quite sure that these cases must have origin- 
ated witliin the hospital, for it would be unreasonable 
to suppose that an insane patient actually suffering 
under erysipelas would be admitted. 

M. Vclpcau, writing in 1831, describes the epidemic 
prevalence of erysipelas m the Hopital de la Piti6, 
where he notices, that both in the medical and surgical 
wards the application of leeches, a trivial operation, or 
even an accidental puncture, brought on this inflamma- 
tion with all its consequences. Blache and Chomel 
also mention the epidemic prevalence of erysipelas, and 
instance the autumn of 1818, a year of excessive heat 
and long drought. Of all the Paris hospitals, the Hotel 
Dien is that which has suffered most frequently and 
most severely by this terrible scourge of hospital esta- 
blishments. 

There is not. I believe, a single hospital in London, 



Jbik

210 OOmiEXIOlf OF ERTBIPELA0 

m 

which has not, at times, been afflicted in like manner. 
At St George's I have several times seen erysipelas so 
prevalent that operations were postponed for fear of the 
patient being subsequently attacked by it 

A connexion of more than twenty years with the 
Small Pox Hospital has given me abundant opportuni- 
ties, not only of confirming the truth of these positions^ 
but of showing that we may carry our views much 
further. I feel persuaded, ^r^, that erysipelas may 
commence in an hospital without the suspicion of im- 
portation. 2. That being so generated, from bed to 
bed, it may spread by contagion. 3. That the miasm 
generating erysipelas is identical with that which in 
lying-in hospitab generates puerperal peritonitis, which 
in foundling hospitals and workhouse nurseries gives rise 
to pudendal gangrene and umbilical ulceration — ^which 
in army hospitals generates hospital gangrene — which 
in hospitals differently circnmstanced is found to occa- 
sion a malignant form of cynanche, both mucous and 
cellular, with otitis, glossitis, an asthenic form of laryn- 
gitis, and sometimes the most aggravated type of typhus 
gravior. 

The origin of scurvy in crowded and ill regulated 
ships is obviously a branch of the same general doctrine. 
A destructive miasm is there generated which is far 
more injurious to the human frame than the use of sah 
provisions. Whatever be the exact nature (or essence) 
of the miasm which thus generates erysipelas, peritoni- 
tis, gangrenous ulceration, or scorbutic blotches, it is 
something depressing to the vital power. 

The dependence of erysipelas on a miasm sid generis 
is no new doctrine. It has been stated over and over 
again, by individual writers, but it has never, I think, 



WITH OCHLETIO HUSH. 



311 



been urged by sjsteraaric authors with the importance 
which it merits; nor has the doctrine been received aa 
one of the avowed axioms of pathology. Dr. RoHo, in 
a treatise entided " A Short Account of a Morbid Poison 
acting OH Sores," and published very early in this cen- 
tury, distinctly announces the principle, and illustrates 
the intimate connexion between erysipelas and hospital 
gangrene, 

[We would remind our readers ibat our autbor has given the name 
of ochUtie miiisni (from ox^'Ei " crowd) to the peculiar miasm generated 
ia hospitals, crowded apartments, &c., &c., and the generic title of 
OcHLBsis, to tbe several forms of inti'mal and external disease thenoe 
ansing, (See Medical Timet (London), Mar. 31, 1849.)] 

The circumstances which lead to the development 
of ochletic miasm have never been investigated with alt 
the accuracy which is desirable, and of which the sub- 
ject is certainly susceptible. The first in importance is 
andoubtcdiy overcrowding of the wards of an hospital 
When the French academicians (I think it was early 
in the French Revolution) were laboring diligently to 
reform (he abuses in the Hotel Dieu, some of them were 
at the pains to calculate in how many hours, supposing 
the ward to have been hermetically sealed, all the patients 
ID it must necessarily have died, presuming that each 
adnit requires for his support a gallon of air per minute. 
The time was wonderfully short, 

2. But it is not numbers alone which are to be con- 
sidered. A ward might safely hold fifty cases oi sitnple 
fracture, which would not with safety contain twenty 
cases of compound fracture. Something, therefore, 
depends on the nature of the disorder. AH disorders 
which tlirow out diseased secretions are more apt to 
taint and vitiate the air, than those where no such 



I 



212 ocHLETic miasm: 

secreting process goes fonvard. It is on this account 
that the wards of the Small Pox Hospital are so pecu- 
liarly liable to generate ochletic miasm. 

3. Another element of great importance in determin- 
ing the sources of ochletic miasm is the degree of 
attention bestowed on cleanliness. If the bed linen, 
mattresses, palliasses, sheets, and blankets, be frequently 
changed, the floors well cleaned, and the walls fre- 
quently whitewashed ; if the nurses be careful to carry 
away all foul secretions, and to purify the patient's body 
by abundance of soap and water ; in short, if the inter- 
nal regulations of the hospital be good, miasm would, I 
suppose, be rarely engendered, even though the ward 
were crowded. 

In the summer of 1844, 1 saw at the Vache in Buck- 
inghamshire, a nursery of 500 young pheasants brought 
up by hens. The attendant informed me that the great 
secret of securing the health of the young brood is to 
change the sleeping ground daily. If the locality of 
the encaiuped aviary was not thus changed, a disease 
speedily developed itself which was extensively fatal. 

4. A fourth elouiont must enter into the calculation, 
and that is, a good supply of fresh air. This by some 
is considered all in all ; but it is not so, and all the ven- 
tilation in the world, conducted on the most scientific 
principles, and superintended by Dr. Reid himself, would 
fail in preventing ochletic miasm, if feather beds and 
bolsters, soaked in unhealthy discharges, are permitted 
to remain in the ward. 

5. Dr. liollo has advanced a step further in the 
analysis of the sources of ochletic miasm, and maintains 
that the disposition to erysipelas and its correlative dis- 
eases (puerperal peritonitis and hospital gangrene) 



OPINIONS RESPECTINQ IT. 



213 



depends partly on a peculiar but hitherto uudctected 
conditioQ of the atmosphere. He is led to this opinion 
l)j observing tlmt erysipelas sonietiuies shows itself in 
the airiest, least crowded, and best regtdated hospitals. 
Without stopping to inquire how much is due to this 
circumstance, we are fully warranted in saying that the 
state of the atmosphere must not be lost sight of in such 
an investigation. We know, on the authority of JJr. 
Lind, that in Batavia aud other localities notorious for 
malaria, hospital gangrene and erysipelas, and every 
sort of associated disorder, prevail with intensity at cer- 
tain seasons. 

Assuming it as proved, that erysipelas is liable, from 
one or more of the five causes now detailed (viz. accu- 
mulation of persons, character of the discharges, want of 
cleanliness, want of ventilation, constitution of the atmo- 
sphere), to spread epidemically, it is still to be shown 
that this disease throws off contagious emanations, 
which can, per se, independent of any such inOuences, 
propagate the ]ike complaint. 

Ur. Weils has met this question very fairly by detail- 
ing a variety of cases where erysipelas spread by conta- 
gion in private homes, and under circumstances calcu- 
lated to exclude all agency save that of simple contagion. 
I will state to you a few of these cases ; first, because 
the doctrine of contagion in erysipelas is distrusted on 
the continent, aud by many, too, in this country ; and 
secondly, because it is important either to establish or 
to negative the statement. 

On the Sth of August, 1796, Dr. Wells attended, in 
Vine street, Clerkenwell, an elderly man, named Skel- 
ton, with erysipelas of the face, who died. A few days 
after his decease, his wife took it, and died also. 



214 OTHER SOURCES 

Shortly after that, Skelton's nephew, a yonog man, who 
had visited his uncle daring his ilhiess, took erysipelasi 
and sarvived only a few days. On the 19th February, 
Dr. Wells was called to attend Mrs. Dyke, the landlady 
of the house in which Skelton and his wife had died, 
and she also was found to be laboring under erysipelas. 
She had attended them in their sickness ; and after their 
death, furniture from their room had been removed to 
her apartment 

Dr. Fitcaim (a most acute physician) attended, in 
February, 1797, a lady with child-bed fever, who had 
erysipelatous inflammation in her skin. Her new-bom 
babe had erysipelas of the pudendum, and both mother 
and child died after a few days' illness. Eight days 
after the death of the child, the lady's mother and a 
servant maid, both of whom had attended the child in 
its illness, were attacked with erysipelas faciei^ from 
which both recovered. 

Many similar cases are recorded. It is not meant 
to insinuate that such are common. In by far the 
larger proportion of cases where erysipelas invades pri- 
vate families, no such result follows, — no member of 
the family, no nurse sickens, but the possibility of such 
an occurrence is to my mind satisfactorily proved. 

[Similar instances of the spread of er}'8ipela8 in private bouses have 
occurred under my own observation, and doubtless also to others ; but 
the question may properly be asked, whether the small proportion of 
cases in which such communication takes place, does not afford fair 
ground for the supposition that some other caiuse, as, for instance, epi- 
demic influence, or vitiated excretions from the patient first att-icked in 
a small apartment, in conjunction with still other causes, may not have 
been the occasion of such propagation in these cases, instead of contagion, 
a term, the use of which ought perhaps to be restricted to specific commu- 
nicable diseases.] 



OF ERYSIPELAS. 



emains, before I bring this branch of the subject to 
a conclusion, that I iaforni you nhat are the circum- 
stances, independent of contagion and miasm, which are 
believed by pathologists to induce erysipelas. Here 
another wide field of inquiry opens before us, 

I told you that the miasms of small pox, measles, and 
scarlet fever, operate on the humau body without pre- 
disposing causes. A child in the most perfect health is 
even more susceptible of these diseases than one out of 
health. That is not tlie law with erysipelas. It has 
long been kuown that certain conditions of the body 
favor very much the development of erysipelas. 

1. Weakness of the body, whether the result of ener- 
vating employments, of prior ailment, or of bad food. 
contributes to bring the frame under the dominion of 
erysipelas. Hence it is that erysipelas is so frequent a 
consequence of typhus fever, of small pox, and of all 
febrile diseases which seriously reduce the vis vitEc, 

2. Erysipelas is a frequent complaint in mihtary hos- 
pitals. It is met with in soldiers of full habit of body, 
as well as in those of intemperate tiabits of life. It has 
therefore for its predisposing causes plethora and an 
inflammatory diathesis. Medical men who have only 
seen erysipelas in the wards of a London hospital, have 
little idea of the phenomena which it presents, and of 
the treatment which is required, when it invades the 
plethoric soldier in the prime of life, eating abundantly 
of animal food, drinking to excess of bad wine, and 
exposed at night, without exercise, to the chilling damps 
of an unwholesome atmosphere. Some of the most 
formidable cases of erysipelas initiate in these circum- 
stances, 

3. The third source of erysipelas, independent of spe- 



216 SOURCES OF BRTSIPELAS. 

cific miasm, is original delicacy of stracture and consd- 
totion. Women, formed of more delicate materials^ 
and often endowed with less of constitutional power 
than men, are thereby rendered more liable to erysipelas. 
Some women, of weakly habit, and yery delicate texture 
of skin, hardly pass a year without an attack. This 
delicacy of skin is hereditary, being transmitted, like the 
lineaments of the fiice or the color of the hair, from 
mother to daughter. Hence it is that erysipelas, like 
gout and gravel, is hereditary in certain families. In 
persons thus predisposed, erysipelas may be brought out 
by cold, by heat, by any violent exertion, by strong 
emotion of mind, by a deranged state of the liver and 
digestive oi^ns, by atmospheric changes, especially the 
setting in of the winter season. 

[Of 373 cases of this disease which occurred at the hospital of 
Stuttgart from 1828 to 1838, 117 were males and 256 females. Frank 
gives the proportion of females to males as high as 4 to 1, and Phillips, 
of London, in the proportion of 3 to 2. 

In 630 cases distributed by the Bureau central, to the various hospi- 
tals of Paris during the years 1830 and 1831, there were 326 females* 
In 43 cases observed by Louis, 25 were women, as were also 13 out of 
20 patients with it received into Chomers clinical wards at La Charity 
Hospital.] 

4. The last of the common causes of erysipelas is 
breach of surface. In the very worst wards of an hospi- 
tal, in the most unfavorable weather, in a habit of body 
originally most prone to erysipelas, it often happens that 
the disease is not developed until the surface of the body 
be abraded or wounded. AH sorts of wounds, whether 
made by leeches, lancets, the knife of the surgeon, the 
sword of the enemy, or the forceps of the dentist, all 
sores and ulcers, are at times followed by erysipelas. 
You may naturally inquire, why ? The reason proba- 



INOCULATION OF ERYSIPELAS. 



217 



biy is, that erjsipelas is the product of a morbid poison, 
and we know that all morbid poisons are more easily 
received by a wounded surface than by a whole skin. 
This doctrine applies to small pox, cow pox, measles, 
aud hydrophobia. The disease is, in fact, thus intro- 
duced by a kind of iuoculation. All breaches of sur- 
face, then, favor the development of erysipelas. It is 
tftere, where the action begins, and from which, as from 
a centre, it is diffused over more or less of the superfi- 
cies. Let me further remind you that erysipelas may 
be excited artificially, by a burn, a scald, a mustard 
poultice, ammonia, or cantharides. The iuflammatioo 
excited by a blister is erysipelatous. 

Dr. Willan was of opinion that erysipelas could be 
propagated by inoculation. He tells us that the fluid 
secretion of the vesicles will occasion a red, painful, 
and diffuse inflammation of the skin, in all respects like 
that of true erysipelas. These experiments ought never 
to have been made, and do not appear to have ever 
been repeated. The facts, therefore, are open to doubt. 
I have heard of a case where vaccine matter taken from 
the arm of a child laboring under erysipelas com- 
municated both diseases. But it did not fall under my 
own notice, and possibly may have been misrepre- 
sented. 

From this sketch of the pathology of erysipelas you 
will see how intricate the sabject is, and how widely it 
behoves you to extend your views, if you would fully 
inform yourselves of its sources. 

The latent or incubative period of the erysipelatous 
miasm is very short, certainly not exceeding one week. 
It is capable, like other miasms, of attaching itself to 
fomites, aud, so far as I have observed, is more difficultly

banished from such fomites than any other known con- 
tagion. 

pn an epidemic which prevailed at Petenburgh (Virginia), during 
the muter and spring of 1844-45, according to the observations of Dr. 
Harrison, in Sussex county, the period of incubation in 14 cases was, in 
every case, seven days. (Peebles on Epidemic Erysipelas, Amer, Jomr* 
Med. ScLy Jan. 1846.)] 

Erysipelas sometimes begins without any yery per- 
ceptible marks of fever. In general, however, when 
this happens, the succeeding disorder proves very mild, 
and some nosologists have refused to apply the term 
** erysipelas" to it They would fain restrict that desig- 
nation to cases of a more noble character, such as are 
preceded by fever, and accompanied in their progress 
by well marked constitutional disturbance. To the 
milder forms of rose-rash they appropriate the term ery- 
thema. This nosological refinement is wholly inappli- 
cable in practice. You will find that in nature a gra- 
dation can be traced from the mildest form of local 
erythema without fever to the most aggravated case of 
constitutional, epidemic, and perhaps fatal erysipelas. 
No precise point can be fixed upon as the boundary of 
erythema and erysipelas. 

Keeping this principle in view, I will tell you what 
are the kind of symptoms present when a person is 
breeding afebris erysipelatosa, whether within the walls 
of an hospital or in a private house — whether succeed- 
ing a wound, or arising from some obscure internal 
cause — whether ultimately to develop itself on the face, 
or on the extremities. The patient has a rigor^ fol- 
lowed by heat of skin. His tongue becomes white ; he 
feels languid and incapable of the exertion, mental or 
bodily, which previously was easy to him. Very often 



PHEN01IE^A OF ERYSIPELAS. 219 

there is sickness at stomach, and vomiting. I know no 
symptom more common than this. You will remember 
how it accompanies the onset of small pox. I have 
seen the same, equatly severe and long continued, during 
the incuhadve period of erysipelas. Other symptoms 
are also present, such as thirst, headache, disturbed 
dreams, or perhaps complete sleeplessness, confusion of 
thought — but I know nothing which can be called 
cltaracferistk of approaching erysipelas, as contradistin- 
guished from any other kind of eruptive ailment. The 
circumstances in which the patient is placed contribute 
materially to guide you to a right conclusion as to the 
nature of the malady which is breeding. Thus, when 
such symptoms occur, at the Small Pox Hos])ital, ^«^ 
denly, to a man recovering from small pox, we know 
tbat erysipelas is going to show itself, and we are on 
the waich for it. So, in hke manner, at the Fever 
Hosphal, though there, it has happened tUat small pox 
has followed, and not erysipelas. The pulse is pecu- 
liarly quick and sharp during the onset of this disease. 



[M. Grisolle mentions «s a premonitory symptom occurring In two 
tliirds uf llie cases of erysipela.<i, n painful engorgement of ibc lymphatic 
glHuds wliii'li receive the vessels coming from the part about to be 
attacked, although the skin prcseola ss yet no appreciable clmnge in any

tbe erysipelas 1, 3, or 3 days, and sometimes even precedes the redness

Mine symptom. {Traitf tie Pallwl. Interne.) 

It ought U) bo borne in mind, however, that, in quite a number of 
cates, tlie disease, even in a severe form, may come on without premoni- 
tory symptoms, the local affection bein^ the first manifralAtion of it, 
especially in Becondary cases, as in typhus fever.] 

Mr. Amott is of opinion that an inflammatory state 
of the fauces accompanies in every case the initiatory 



220 PHENOMENA OF ERYSIPELAS. 

fever of idiopathic erysipelas. I iiave noticed die same 
circumstance when the disorder has originated from 
ochietic miasm. The intensity of the initiatory fever 
of erysipelas is sometimes excessive. Some years ago, 
a patient at the Small Pox Hospital died during the 
incubation of a fever, which I had every reason to 
believe was erysipelatous. 

[In tlie epidemic of er}'si])ebi9 in Petersburgh, previously referred to, 
Dr. Peebles says that the aft'eetion of the throat was the " only symptom 
invariably present, — in the mildest forms of the disease, the chief symp- 
tom coniphiined of; in the severe and malignant form, one of the most 
formidable complications." He says, a diagnostic mark of the throat 
affliction wjis, the uvula sintfularhj relaxed and elongated, and alwayB 
hai'int/ ifnitj)ended from its ejctrcnuty a j^lUcle of viscid limpid niuctiSy 
somefimcK resting on the tongue, which could be with difficulty removed 
by tho patient or by a sponge. (Awer. Jour. Med. Sei., Jan. 1846.) 

Dr. .1. A. AIlt»n, in his account of an epidemic of this disease which 
prevail, d in MitMlobury (Vermont), in the winter of 1841-42, says that 
the throat was uniformly t'ouiul inrtaniod. {Boston Med. and Surg. 
Jouni., ISJi.)] 

After a period, varying from twenty-four to sixty 
hours, a nHJuoss appears oitlior on tho face or on the 
leg, or sometimes (though much more rarely) on the 
trunk. The redness is soon succeeded by swelling, 
and a sense of heat in the part. The redness and 
swelling extend. When the eruption attacks the head, 
the side of the nose is g(Mi(»rally the part first allected, 
hut sometimes the temj)le or ear. The swelling soon 
reaches the eyelids, which assume a peculiarly puffy or 
cedematous aspect, and often the eyes are for a thne 
closed. Should the disorder prove severe, the face may 
swell to such an extent as to present a truly hideous 
spectacle, all trace of the natural features and expression 
of countenance being entirelv gone. The extent of

221 



surface occupied by redness is extremely varied. I 
hare seen erysipelas erase when one side ouly of the 
face had become affected. I btive seen it extend from 
the scalp to the neck, from the neck to the breast, and 
there suddenly stop. At other times, it descends to the 
extremities, and ceases not until every portion of the 
sVn has been successively attacked. Such cases, how- 
ever, are very rare, for in general before that can take 
place, some internal organ has become affected, the 
coQStitution has given vi'ay, and the patient been carried 
off, either by coma, vomiting, or diarrhcBa. 

[Erj?aipelaa sometimes attacks the scaip without extjinding to ihe 
facv, but diU form of the dise.ise is so rare, that M. Cbomel hns not 
i«eii more thuti three or four cases of it, A cose is recorded by M. 
Grisolle {Brit, and For. Med. Hev., April, 1848, p. 547, talieti from 
L'Union MfdicaU, No. 14), in which the earliest Bjiuploms were a 
stiShesB of the neck and enlargement of the cervieal glands, the latter 
being a very common, though not a constant precursor of the disease. 
The ayinptoms of this furm aro often very obscure. Pain and i^emft 
of the scalp are, however, usually present, and redness may be seen on 
close examination, Vesicles never form on that part, but numerous 
small sbtMMsseB sometimes appnr at the close of the disease. Delirium 
ia one of the most unfavorable symptoms, but is only sympathetic, and 
not owing to inllHmmation of the brain or its membranes, as proved by 
the autojwe-s made by MM, Chomel, Louis, and GrisoUe.] 

The redness of erysipelas is easily distinguished. It 
fades under the finger. It is bounded by a distinct 
ma^n. The skin occupied by it is soft and inelastic. 
It is accompanied by a sense of heat, or scalding. 
There is no throbbing complained of, nor any sharp 
lancinating pain, as in phlegmon. 

[Tliis dinlinctly marked, slightly elevat<-d margin is characteristic of 
erjsipehis, and is always produced at the limit of its extension every 
litnu there i« a tendency of the disease to extend itself. Chomel 
remarks that, by means of this conterminous Bwelliog, the periods of

shifting may be rcix>guised, and by its absence, the period of definite 
limitation ; and that this double character is of importance, esj>ocially 
when we wish to determine the value of remedies said to check the 
progress of the erratic form.] 

Very mild cases of erysipelas sometimes subside with- 
out any further appearances than those now described ; 
but in all cases of even ordinary intensity, the cuticle 
becomes (in a period varying from twelve to thirty-six 
hours) elevated into small vesicles, blebs, or blisters — 
precisely like those which form after the application of 
a plaster of cantharides, or which we see after a burn or 
scald. These blebs or vesicles contain a thin ichor or 
serum, sometimes perfectly transparent, sometimes yel- 
lowish, sometimes livid, and occasionally mixed with 
blood. They soon burst and discharge their contents, 
while the subjacent surface of the corion becomes of ti 
reddish brown, or perhaps livid color, according to the 
degree of constitutional power present. The cuticle 
over the whole extent of the erysipelatous surface is 
killed, and dcstjuamates, as in scarlatina, in the course 
of the succeeding fortnight. 

1 have told you that the cutis vera may assume a livid 
aspect. I may add, that at times erysipelas exhibits 
still more aggravated and even appalling appearances. 
Pure gangrene supervenes, the constitution sympathizes, 
and the patient dies in the course of a week (generally 
about the third or fourth day), with symptoms of 
oppressed brain (coma or convulsion) — or with von)it- 
ing and diarrhoea — or with oppressed breathing and 
excessive restlessness. In these cases, prior to the gan- 
grene, the skin appears hot, tense, and acutely painful 
The pulse is rapid, almost beyond counting, and the 
expression of countenance betrays the utmost anxiety. 



ERYSIPELAS OANGRENOaUH. 

Nowhere is ibis frightful fcirin of erysipelas gmigrefu)- 
sum more frequently witnessed than in badly- ventilated, 
over-crowded, and ill-regulated foundling hospitals and 
workhouse nurseries. The erysipelas neoDatoruin, and 
the erysipelas pudendorum vicerans, have been described 
by Dr. Gartbshore, by Dr. Underwood, by Dr. Pcrcivai 
of Manchester, and Mr. Kinder Wood of Oldham. 
Fortunately, we have not many opportunities of seeing 
such things in this country, Imt on the continent, where 
foundling hospitals are in fashion, the disease, in all its 
malignity, is still occasionally witnessed. It artacks 
children from the period of birth to the second monlh, 
or even later, and chiefly aflects the umbilicus, geuilals, 
and groins. 

On dissection of lliose who have died of this disease, 
Dr. Garthshore was unable to detect any lesion of the 
internal viscera, nor was the cellular membrane aflfectcd. 
The skin was the only organ diseased. Death was the 
result of the morbid condition of the fluids, engendered 
by a malignant miasm. 

Isolated cases of erysipelas gangrenosum may occa- 
Monally be seen, iu all our hospitals, affecting adults. In 
former limes it raged epidemically. Wc read that 
during the middle ages, the gangrenous erysipelas fre- 
quently ravaged France, where the disorder was called 
the plague of fire (ignis sacer). 

Such are the phenomena of what may be called 
tuperjicifd erysipelas, or what some authors have called 
erysipelas phlyctienodes. It is not often, however, that 
the skin alone receives the whole force of the febrile 
commotion. We must inquire therefore, nest, what 
happens, during the course of erysipelatous fever, to the 
Tteighhoriiig textures; and what other organs suffer. 



224 



EKYSIPELAB PilLGQHONODES. 



lu almost all severe cases of er^'sipelas, wlietlier 
affecting the face or extremities, the suhjaceut cellular 
Diembraiie participates in the disease. luSammation 
spreads to it, and, from the peculiar texture and dis- 
position of this tbtsue, leads to the effusion cither c^ 
serum or pus. When serum alone is effused, patholo- 
gists call the disease erysipelas adematodes. When 
purulent matter collects, ehher in small abscesses, or, as 
more commonly happens, when it is diffused through 
the cells of the cellular membrane, we call tlie disease 
erysipelas phlegmonodes. You will understand that all 
these are only modiiicatioDs of the same disorder, 
attributable to tbe varymg intensity of the inSamma- 
tory action, or some peculiar malignity of the exciting 
cause. 

Tn the progress of erysipelas no organ is more hkely 
to suffer than the brain. I'athologbts are in the habit 
of saying, that a metastasis has taken place to the 
brain, but it is more properly extension of disease than 
change of locahtv. The external parts continue to he 
red, swollen, and blistered. Phrenitis, whh delirium of 
a fierce kind, is sometimes witnessed. At other limes, 
coma and stertorous breathing supervene, and the 
patient dies apoplectic on the seventh or eighth day of 
tbe disease, sometimes even later. Dissection seldom 
displays anything more than turgescence of the cere- 
bral vessels. These cases are singularly untractable. 
Instances of recovery have occurred, but the greater 
proportion of cases of erysipelas (especially of the 
face) comphcated with phrenitis, or coma, prove fatal, 
and that very rapidly.

we believe to be an important practical principle, tbat there is a furm of 
mental diiturbanca in tliis disease entirely different from tljat depeuJing 
upon phreaitia, described by bim, and cbaracterized by a hot skin, 
■trong pulse, injected eyes, Ac^ and connected, indeed, with a pathological 
state directly opposite in ita nature ; though no allusion to such a form 
is made under this head.] 

Occasionally, the stomach is the organ which suffers 
during the progress of erysipelas. I attended, many 
years ago, a gentleman of feeble frame, who, after a 
severe attack of initiatory fever, threw out erysipelas. 
The stomach, irritable at first, iiever recovered its tone. 
Vomiting continiled, and so exhausted the patient that 
he died in one week fi"om the seizure. In pome 
mstances, erysipelas, especially when it occupies any 
large portion of the surface, seems to affect the heart 
sympathetically. There is frequent syncope, with an 
exceedingly feeble pulse. Death takes place here by 
exhaustion, unless the system can be supported in the 
meantime by wine and brandy. Children attacked by 
erysipelas often pi-rish by supervening mucous enteritis. 

[Mr. Robert Adams stales {Dublin Hoipital Reports, toI. W.) two 
cases of erysipelas of the head and face, one traumatic and one idio- 
pathic, nhicb terminated fatally by metasiaus to the serous membrane 
of the heart ; and also alludes to two other cases of a similar nature 
■een by others, and a specimen of the morbid appearances presented by 
the dissection of another similar case, preserved by Mr. Cusack in the 
muieum in Park street, {Amer. Jour. Med. Set., vol. i. p. 433. )J 

These intimations of the several sources of danger and 
of death in erysipelas will preclude the necessity of any 
formal inquiry concerning prognosis. I will merely 
observe that erysipelas of the face is, cteteris paribus, 
more dangerous than erysipelas of the extremities. 
Nevertheless, gangrene is rarely observed as a con- 
sequence of erysipelas faciei. This termination is more 
15 



226 STATISTICS OF ERYSIPELAS. 

frequent in the erysipelas of parts at a distance from 
the heart (the scrotum and extremities). Erysipelas 
faciei most commonly proves fatal by supervening 
affection of the brain. 

[Colles says (Lectures on Theory and Pract, Surgery), " delirium or 
coma coming on before the local inflammation, docs not indicate dan- 
ger ; but this is not the case when the eruption, accompanied by slight 
constitutional symptoms, has already continued for two or three days.*^ 

Erysipelas is most to be dreaded in weakly habits, 
and constitutions exhausted by previous illness. Ery- 
sipelas from miasm and contagion is more dangerous 
than erysipelas from internal causes. The extremes of 
life suffer from it more than the middle periods. 

[For an account of a form of erysipelas which has prevailed at differ^ 
ont periods within a few years past in various parts of this country, 
under tho name of " Black Tongue," see Appendix K.] 

With reference to statistics, I have not much to tell 
you that can be relied on. When the inquiries now in 
progress in the several London hospitals, under the 
guidance of the Statistical Society, are fairly carried 
out, and an average of years taken, much will be 
elicited on this subject that is curious and edifying. 
At present, all is guess-work. It has been conjectured 
by Dr. WilUanis that the rate of mortality varies from 
one in three to one in fifteen (thirty-three per cent, 
down to six or seven per cent). With respect to the 
actual numbers perishing by erysipelas, we learn from 
the registrar general's reports, that in the metropolis, 
during the five years, 1838, 1839, 1840, 1841, 1842, the 
deaths by erysipelas have been respectively as follows : 
—405, 301, 311, 251, 235. Throughout England and 
Wales, the deaths by erysipelas were, in 1838, 1203 ; 



BTATISTIOB OF ERYSIPELAS. 



227 



in 1839, 1140; in 1840, 1217. The steadioess of 
these numbers will attract your attention, so different 
from the fluctuations of the true exanthemata. You 
will notice at the same time that erysipelas is compara- 
tiveiy more prevalent and more fatal in the metropolis 
than in the provinces. The general mortality of the 
one, compared with the other, is as four to one, but in 
the case of erysipelas, it is as eight to one. Such a 
result might have reasonably been anticipated from a 
knowledge of the character and constitution of the 
parties admitted into the hospitals and parochial infir- 
maries of London, and also from considering the com- 
parative purity of the air in town and country hospitals. 

Females unquestionably exhibit more cases than 
males in point of number, as already noticed ; but this 
is compensated by the greater intensity of erysipelas in 
males (from drink, mental exchemeut, tStc), so that( in 
feet, as many males die of this disease as females. In 
1838, there died (throughout the country) 605 males, 
698 femalejs. In 1839, 550 males, 590 females. In 
1840, 450 males, 456 females. In the metropolis, the 
proportioa of male deaths exceeds slightly those oC 
females. 

[Of 420 ileallia by erysij^laa in New York from 1837 to 1844 inclu- 
live, SOO were mnlea and 220 females. Great inequality prevailed 
during individual years of tfaia series, sometimes in favor of one sex, and 
■ometimeo in favor of the other. Of 264 deatlis by this disease in 
Fhilndelphia, during the period from 1837 to 1846 inclusive, the num- 
ber of Uiose of the two ee.xes was predsely equal ; but, as in New York, 
there was great inequality of tbe two sexes in individual years of the 
series.] 

In like manner, all ages seem to suffer in nearly the 
same degree. There died of erysipelas in London 
daring the two years 1840-41, 562 persons, of whom

172 were under fifteen years of age» 265 were adohs 
in the prime of life, and 123 were aged above mitj, A. 
more minute investigation, however, establbhes that 
the aged are its chief victims. If we compare the 
number of deaths with the numbers living at each 
respective period of life, we shall find that erysipelas is 
most fatal in advanced life, less so in eariy life, and 
least so in middle life. The proportions are expressed 
by the figures 55, 15, and 11.

We come now to the thorny subject of treatment 
Erysipelas is obviously a highly inflammatory complaint 
It displays most strikingly all the phenomena of inflam- 
mation — pain, heat, redness, swelling. Nevertheless, 
physicians for more than a century past have been 
divided as to the proper mode of treating this inflamma- 



BLOOD-LETTINO AND PURGATIVES. 



tiou. Some contend for bleeding, purgatives, and the 
usual anliphlogistic measures. Others still more forcibly 
urge the adoption of bark, wine, and a system essen- 
tially tonic. The great authorities are ranged pret^ 
equally on both sides. Cullen, Lawrence, Dupuytren, 
are opposed by Drs. Wells, Willan, and Fordyce. 
Some who recommend wine object to bark, and at all 
events deny to bark that specific power over erysipelas 
which Dr. Wells and Dr. Powell claim for it. 

Out of this mass of conflicting opinion it is difficult 
to extract any decided rule of practice. Facts are 
opposed to facts. Statistical inquiries, carefully con- 
ducted so as to guide our judgment, are wanting. In 
this emergency I must tell you what I liave noticed 
-myself, and what I believe you will find to be the safest 
course to pursue. 

We have seen that erysipelas arises from a great 
variety of causes, and may display itself under circum- 
stances the most opposite. It may happen to the ple- 
thoric soldier and the exhausted inmate of a workhouse. 
It may invade a young man in the prime of hfe, and a 
female of hysterical habit and feeble powers. It may 
arise from a depressing miasm, and it may follow a 
debauch of wine. Common sense dictates that any 
disease so occurring must be met by corresponding dif- 
ference of treatment 

As an army surgeon, yoa will often find it necessary 
to bleed largely in erysipelas. If the pulse be full, the 
tongue deeply loaded, and the urine of the color of 
brandy, nothiug but full bleeding from the arm will 
meet the exigencies of the case. I remember, some 
years ago, being catlvJ to attend a young man in erysi- 
pelas, aged about twenty-one, the apprentice of a 



232 LOCAL TREATMENT. 

TMicn the disease affects the face and head, it is important to keep 
the patient in an inclined posture in bed, so that the head may be 
elevated ; and also to keep it uncovered, to prevent accumulation of 
heat 

Particular care should also be taken to keep the part elevated when 
either extremity is affected.] 

If pliysiciaDs have differed on the canstitutional 
treatment of erysipelas, they have not agreed better 
with regard to local treatment. Some advise warm 
applications, some cold ones. Some recommend watery, 
some^ spirituous fomentations. Some banish all fluid 
applications, and place their sole reliance on dry hair 
powder. A few would counsel us to cover the affected 
surface with mercurial ointment. Others have great 
confidence in lotions containing lunar caustic ; and a 
few, in their admiration of this remedy, pretend to con- 
trol the advance of erysipelas by surrounding the affected 
part with a ring touched by the lunar caustic, and say- 
iiiji; to the inflammation — " Hitherto shalt thou come, 
and no farther." Here and there a practitioner, some- 
what more energetic in his notions, applies a blister to 
the very centre of the inflamed surface. 

I shall not occupy your time by niinuto criticism on 
these several modes of practice. All of them have, at 
times, proved useful — that is to say, patients have done 
well under them all. In truth, it would be as absurd to 
limit the local, as it would be to confine the constitu- 
tional treatment to any precise detail. The feelings of 
the patient may often be consulted advantageously, and 
that plan adopted which best moderates the sensation 
of heat and fulness which is so distressing to him. 
You nmst not expect much decided benefit from any 
kind of local treatment in a disease of constitutional 
origin. 




LOCAL TREATMENT. 



You are not to neglect any means, however ; 
rently trifling, which conlribiite to the ease and tempo- 
rary comfort of the patient, but you are not to exagge- 
rate the importance of external treatment, or to imagine 
you iiave made a great discovery, when you find a 
patient prospering better under a decoction of poppies 
than under a cold spirit lotion. 

In mild cases, the surface may be covered with hair ■ 
powder. In severe cases, the affected parts may be 
painted with a lotion composed of a drachm of lunar 
caustic dissolved in eight drachms of distilled water, 
with eight drops of diluted nitric acid added. 

I have left to the last the great bone of contention, 
touching the propriety of local bleeding in erysipelas. 
This question admits of being viewed in a great variety 
of aspects. Mr. Lawrence and Mr. C. Hutchinson 
contended for the honor of this improvement in the 
treatment of erysipelas. I will state to yon, in a few [ 
words, my own opinion on the subject. In erysipelas, 
there is undoubtedly great congestion of the superficial 
Tessels, and, therefore, d. priori, great benefit might be 
anticipated from the detraction of surface blood. Under 
careful management, and with due regard to the powers 
of the system, scarijicalions in erysipelas may be prac- 
tised with great benefit upon the extranities. I have 
my doubts as to the propriety of employing them on 
the face. I enter my protest, however, most strongly ' 
against those deep incisions through the entire tliick- 
ness of the inflamed and swollen chorion which some 
sui^eons have recommended. If the object be to" 
obtain a large quantity of blood, that object would be 
gained more safely, and as effectually, by veneseriion. 
It is difficult, in aU cases, and impossible in some, to 



^^ 




control or limit the loss of blood proceeding from 1 
gaping lips of a deeply incised erysipelatous surface ; 
and I need scarcely tell you tbat exbaustion from the 
excessive loss of blood in such a disease as erysipelas is 
a very serious evil. Many cases of erysipelas have 
undoubtedly been benefited by die detraction of surface 
blood, but many thousands of equally severe cases ha^ 
done well without it 

[Altliough we fully agree with our author in the amull 
confidoEw to be placed in local romediea in an affection s 
connected with constitutional causes, as is the case wilh erysipelas, a! 
have indeed oureelves seen but little effect from them in arresting i 
progrera of the disease, no havo thought that a notice of thoee whii 
have been recommended by high authority, and are more or 
common use, might not be unacceptable — tlie more especially a 
of them are at least palliatives, and often serve to soothe tlie local ii 
(ion, and thus contribute materially to the comfort of the patient 

Mercurial ointment has had many warm advocates as a topical ap[ 
cation in erysipelas. 

Lisfrinc thought that lard itself is a good local application ii 
affection, and that it may be eubstjtuted for mercurial ointment. 
Bays that it should be renewed every two hours, and ^veo ever 
hour, if the parts are hot and the weather warm. 

M. Jobert recommends ointment of nitrate of silver, which he n 
three degrees of strength, according to the intensity of the disease, 4 
and 12 parts to 30 parts of lard, to be applied freely. lie also a; 
compresses, wet with tiuct. camphor in the simple form. M. Jot 
says, however, that local remedies have no effect in arresting the p 
grcss of the disease on the skin ; but that ointment of nitrate of s:

The act of 1840, commonly called tlie Vaccination Ex- 
tension Act, — though not nominally, yet in its practical 
working, is an act for enforcing the practice of vacci- 
nalion on the whole population of these kingdoms; for 
with the penalties of that act staring ns in the face, our 
only choice hcs between accepting vaccination, or 
exposure lo the casual small pox. The latter alternative 
has coupled with it the passage tlirough life in a state of 
cvnstant and uiiserahle suspense, the disorder perhaps 
seizing upon the individual at last under circumstances 
the most distressing — possibly, after having married, and 
become the father of a family, all of whom are depend- 
ent upon tiiin for support. No parent in his senses 
could seriously hesitate when such an alternative is set 
before him. The whole population of England and 
Wales, therefore, are virtually by this act cojnpi-Med to 
submit to vaccination, whether they like it or not. 
Formerly the case was diOercnt. Inoculation was 
allowable, and if people adopted vaccination, it was

their own act and deed, for which no one could 1 
blamed. Now the government of the country int« 
poses, and takes the responsibility on Us own shouldei 
The measure was a strong one, but it had been adopt€ 
in foreign countries, and found to answer. It rendei 
more tlian ever necessary, that everything connect 
with vaccination should be carefully studied by you — ia 
history, pathology, phenomena, and practice. Tha 
points will occupy our attention during the present lei 
ture. I shall, on a subsequent occasion, speak to yea 
concerning the practical results of vaccination, and i 
Statistical details by which we have, after an experienci 
of forty-five years, arrived at a knowledge of its ra 
efficacy. 

The earliest notice I have ever seen of cow pox is H 
be found in a weekly paper published at Gottingen, 3 
1769, where we leara that such a complaint was i 
uncommon in the neighhorliood of that town, and l 
those who caugltt it from the cows flattered themselw 
ihey were secure from the infection of small pox. 
notion of the same kind had long prevailed in Gloucsi 
tershiro — a great dairy county, as you know, — and haj 
often been forced upon the attention of the provincul 
surgeons. But no one thought seriously of this i 
tradition, or dreamt of applying it to the general benefil 
of mankind, until Jenner arose. Dr. Jenner was bon 
at Berkeley, in Gloucestershire, on the 17ih May, 174i 
He displayed an early taste for natural history, and wa< 
thrown from infancy among dairies and dairy maidi 
There he heard of the cow pox, and appears, almost ' 
from die first, to have foreseen tlie uses to which it 
might be turned. 

In the year J770, being then twenly-one years of 



Md 



DEVOTION OP iBNKBR- TO THE SUBJECT. 



age, Jenner came to London, to prosecute his medical 
stndies under the eye of John Hunter. To that 
enlightened man he repeatedly mentioned the popular 
rumors prevalent in Gloucestershire concerning cow 
pox ; but he does not seem to have received much 
encouragemeut to prosecute the inquiry. In 1775, 
being then engaged iu practice at Berkeley, he devoted 
more attention to the subject He often talked the 
matter over with his professional friends and neighbors. 
Among them was Mr. Fewster, of Thombury, who 
had, in his early days, been associated with Sutton, tlie 
great inocnlator. This circumstance naturally inspired 
him with a warm interest in everything connected with 
small pox, but he never would beUeve in the prophylac- 
tic power of cow pock. Other professional friends, in 
like manner, dissuaded Jenner from wasting his time on 
what they thought a barren study, " We have all 
heard of these stories," they would say ; " but the real 
caasc of the anomaly is some peculiarity of habit in the 
person who escapes, not any efficacy in the disorder 
received from the cow." 

These and such like arguments would have effectually 
damped the ardor of most men ; bnt though discouraged, 
Jenner was not to be driven from his favorite pursuit. 
No opportunity was neglected by him which seemed 
likely to throw additional light on the subject. Cow 
pox appeared to be the object for which he mainly lived. 
He searched out all conceivable sources of failure. He 
learned to discriminate the various forms of eruption to 
which the teats of the cow are subject at different 
periods of the year, and was led to the belief tliat one 
only was possessed of specific or antivariolous powers. 
This he called true cow pox. The others he termed 



240 



ANNODHCEHENT OF THE 



spuriotts cow pox. By degrees he convinced himsel 
that all tlic anomalies supposed by his professional 
brethren to be insurmountable obstacles to the succei 

I of his pursuit, were explicable on scientific principle! 
and that cow pox was, what the nninstructcd bclicvei 

I it to be, a true. Cull, and efficient preservative against t 
small pox. 

It would seem that about the year 17S0 he first coaj 
ceived the magnificent project of perpetuating and pre 
pagating this disease by inoculation, and thus extending 
its benefits to the whole world. In 1788, he visit« 

' London, and carried with him a drawing of the casaa] 

I cow pox as it appears on the hands of the milliera.1 

' This he showed to Sir Everard Home and other greatT 
men of that day, but the physicians of London saw in il 
only a curious and barren fact. Dr. Adams, physiciaaj 
of the Small Pox Hospital, noticed the cow pock in I 
" Treatise on the Morbid Foi^ous," published in 1795. J 

It is a very curious circumstance that so far hack i 
1782, when Dr. Archer was physician of the Small Pom 
Hospital, Catharine Wilkins, from Cricklade, in Wilfrf 
shire, who had had the cow pox casually during earln 

f life, was tested with variolous matter at the Small Fox] 

I Hospital, and found to be unsusceptible. 

It was not until the year 1796 that Jenner began I 

I esprrimcnt with cow po-: ahhough he had been talkitij 
and inquiring about it for at least thirty years. Tb 
decisive experiment was made on the 17th May, 179^ 
on a boy, named Edward Phipps, eight years of agi 
He was tested with small pox on the 1st of July of tl 
year, and found to be unsusceptible. 

Jenner now prepared for publication, and sent hiJ] 
paper, carefully and very philosophically drawn up, to 



DISCOVERY OF VACCINATION. 



241 



the Royal Society, wishing that the discovery sliould 
come forth to the world under its high auspii-es ; hut 
that learned hody declined to receive the paper, lest it 
should injure Jenner's fame, already established hy some 
observations on the cuckoo ! Jenner, nowise discon- 
certed, published the paper himself in June, 17!)S. 

The work was drawn up witli singular skill. An 
air of philosophical calmness pervaded it, which was 
highly attractive. It was not the hasty productJoa of a 
young man au\ions to push himself into early notoriety, 
but the mature opinion of a physician whose life had 
been devoted to a deep and careftd consideration of his 
subject, and who staked his professional reputation on 
the success of the measures which he recommended. 
It is not to be wondered at, that a volume, published 
under such circumstances, mole pnrvum, malerid gravem, 
should have riveted the attention not of physicians 
alone, hut of the whole civilized world. 

It redounds to the honor of St. Thomas's Hospital, 
that its medical officers were the first persons in England 
to put Jenners discovery to the test. Mr. Cline vac- 
cinated a hoy here, in the last week of July, 179S, wirh 
dried lymph, which had been kept three months on a 
quill. The hoy had diseased liip, and Mr. Cline, pro- 
posing to convert the vaccine pock into a pea issue, 
inserted the matter on the outside of tlie hip. Dr. 
Lister, formerly physician of the Small Pox Hospital, 
watched the progress of the case. The boy was inocu- 
lated almost immediately afterwards, with small pox 
matter, in three places, but the slight inflammation that 
arose subsided on the fourth day. The experiment 
therefore was perfectly successful. 

On the aOth January, 1799, cow pock was found in 



242 HISTORY OF VACCINATIOIV. 

Mr. Harrison's dairy, in Gray's Inn Lane, from which 
source, Dr. Woodville, my predecessor at the Small Pox 
Hospital, commenced a series of vaccinations. That 
same stock of lymph remained in use up to the year 
1836. 

To pursue the triumphant career of vaccination would 
be gratifying to me, but it would not conduce to your 
improvement. Suffice it to say, that the new practice 
was received with enthusiasm, not only in this country, 
but over the whole of Europe. It reached India in 
1802, and penetrated with equal rapidity into the wilds 
of America ; for foreign nations vied with us in efforts 
to extend the beneficial practice to the farthest regions 
of the globe. 

[Vaccination was first practised in tliis country by Dr. "Waterhouse, at 
Boston, in July, 1800, with matter received from Dr. Jenner himself, 
lie used it first upon four of his own children, who, consequently, were 
the first vaccinated |)ersons in the United States. 

Dr. Miller, of this city, received vaccina matter from Dr. Pearson, of 
Lond<jn, the same year, but it failed to produce the g(;nuinc disi-a^e ; as 
did also another supply of matter sent on from Boston. [Thacher's 
Amer. Med. Bior/raphtj.) 

The credit of its fii-st successful performance in this city is, therefore, 
due to Dr. Valentine Seaman, who obtained matter tirst from the arm 
of a domestic vaccinated in Boston bv Dr. Waterhouse, who reached 
this city on the 22d of May, 1801, just at tlie proper time for the matter 
to be used. With tliis, his first supply, he vaccinated ei^hte<'n persons, 
when, in consequence of being prevented by severe illness from pursuing 
the subject, the infection was lost. In the course of the following win- 
ter, however, he obt^iined a fresh supply, and by the 22d of DccembiT, 
1802, thirty-five others had undergone the disease, making the whole 
nunilM.T fifty-three, without his having obtain«-d a single coH»jK.»rator. 
(Medical Beposi tort/, vol. v. p. 23(5 ; also, Discourse upon Vaccination, 
by Valentino Seaman, M.D., 1810.)] 

A few detached notices will complete my sketch of 
the history of cow pox. In 1807, Parliament voted to 



INSUSCEPTIBILITY OF COW POX. 



243 



Dr. Jonner a sum, amounliDg, in all, to X30,000, as a 
reward for his discovery, and the generous devotion of 
his time and talents to the pubhc welfare. In 1808, 
the National Vaccine Estabhshment was formed, and 
the support of government given to this measure, though 
not in a very efficient form. 

In 1823, Dr. Jenner died at Berkeley, the scene of 
his early labors, full of years and honors. 

In 1840, a Bill passed the legislature for the exten- 
sion of the practice of vaccination throughout England, 
Wales, and Ireland. The machinery of this act was 
placed under the supervision of the poor-law commis- 
sioners. Payment lo medical practitioners is directed to 
be made, at a stipulated sum (averaging one shilling 
and sixpence) for each successful case ; such expenses 
to be defrayed out of the poor rate. A still later act 
confirms these provisions, with a few unimportant addi- 
tions. This act is working well, and the practice of 
vaccination is now rapidly extending over the provinces. 
Id the metropolis, owing lo the number of well-con- 
ducted vaccine iustitutions, it had always prospered. 

Having thus brought down the history of vaccination 
to the latest period, my next object is to make yoa 
famihar with the several appearances which it presents, 
regular and irregular; but before doing so, I must inform 
yOQ that occasionally we meet wilh persons who. from 
some peculiarity of habit, are wholly insensible to the 
vaccine poison, in whatever intensity and by whatever 
mode it is applied. They receive it as they would so 
mach cold water. The proportion of mankind who 
exhibit this singular idiosyncrasy is very small. 1 may 
have seen thirty or forty such cases in the course of my 
life. It would be very interesting to determine whether 



244 PHENOMENA OF VACCINATION. 

this constitutional inaptitude to cow pox denotes a like 
inaptitude to receive and develop the variolous poison. 
In the few cases which I have seen, where inoculation 
was subsequently tried, the insusceptibility was proved 
to extend to both poisons, but 1 have read of instances 
of an opposite kind. It is at all times very difficult to 
arrive at the truth, on a question of this nature ; and 
DOW that inoculation is forbidden, we may despair of 
ever arriving at any certainty concerning it 

The insusceptibility to the vaccine poison is, in some 
cases, obviously dependent on constitutional weakness, 
displayed in the slowness of dentition, the imperfect 
ossification of the head, and the emaciated aspect of 
bodv. 1 here exists here an atonv of the absorbent 
system. If vaccine lyuiph is inserted into the arm, 
either no vesicles arise, or they arc small, and imper- 
fectly developed. In such cases, the indisposition to 
receive cow pox is only temporary. In the former 
cases, where idiosyncrasy is the cause of the phenome- 
non, the inaptitude continues through life. 

I now proceed to describe to you the phenomena of 
vaccination. 

The regular course of cow pox is as follows: — On 
the third day from tiic insertion of the virus, the wound 
will be perceived red and elevated. By aid of the 
microscope, the efflorescence surrounding the inflamed 
point will be distinctly jierceived even on the second 
day. On the fifth day, the cuticle is elevated into a 
pearl-colored vesicle, containing a thin and perfectly 
transj)arent fluid in minute quantity. The shape of the 
vesicle is circular or oval, according to the mode of 
making the incision. On the eighth day, the vesicle b

in its greatest perfi!ction, its margin is turgid and sensi- 
bly elevated above the surrounding skin In color the 
vesicle may he yellowish or pearly. The qnantily of 
fluid which it contains will he found to vary much. 
When closely examined, the vesicle will exhibit a celtu- 
lated structure. The cells are ten or twelve in number, 
by the floor and parietes of which the specific matter of 
the disease is secreted. The vesicle possesses the um- 
bihcated form belonging to variola. 

On the evening of the eighth day (counting from the 
day on which the incision was made), an inflammatory 
circle, or areola, commences at the base of the vesicle. 
The skin becomes tense, red, and painful, for a consi- 
derable extent around. The figure of the areola is per- 
fectly circular. In some cases the subjacent cellular 
membrane participates in the inflammatory action, and 
occasionally the glands of the axilla swell. The areola 
continues to advance during the ninth and tenth days. 
On the eleventh day it begins to fade, leaving, in its 
decline, two or three concentric circles of a bluish 
dnge. 

The vesicle, by this time, has ehher burst spontane- 
oasly, or been opened by the lancet of the surgeon. Its 
contents now become opaque. The vesicle itself begins 
to dry up, and a scab forms, of a circular shape, and a 
brown or mahogany color. Bv degrees, this hardens 
and blackens, and at length, between the eigliteenth 
and twenty-first day, drops off, leaving behind it a cica- 
trix of a form and size proportioned to the prior inBam- 
malion. A perfect vaccine scar should be of small size, 
circular, and marked wiih radiations and indentations. 
These show the character of the primary inflamniatlon, 
and attest that it had not proceeded beyond the desira- 



d 



246 CONSTITUTIONAL SYMPTOMS. 

ble degree of intensity. Many of the most perfect scars 
disappear entirely as life advances. 

Until the eighth day, the constitution seldom sympa- 
thizes. At that period, however, it is usual to find the 
infant somewhat restless and uneasy. The bow^els are 
disordered. The skin is hot, and the night's rest is 
disturbed. These evidences of constitutional sympathy 
continue for two or three days. There is, however, 
much variety observable here. Some children suffer 
slightly in their general health throughout the whole 
course of vaccination. Others exhibit scarce any indi- 
cation of fever, although the areola be extensive, and 
the formation of lymph abundant. 

[Iq occasional, though rare cases, there is a general eruption of Tacdne 
vesicles over more or less of the ^hole body, resembling in some patients 
those of varicella, and in others those of the genuine cow pock, and 
sometimes a mixture of the two. Two cases occurred among those 
vaccinated in Franco in 1840, in which there was a general eruption of 
pustul(5S over tlie whole body, the fluid from which produced regular 
vaccinia. We have met wiih an instance of this general vesicular erup- 
tion over the body res(;inbling vaccinia, but did not test the fluid con- 
tained in the vesicl(?s. M. Aubry has also j)ublished a case of this kind. 
(Archives de M^d.^ Paris, Sej»t. 1841.) 

In Some instances, vaccine vesicles appear at other than the points of 
insertion of the viru>, and sometimes on parts where no abnxsion existed 
which could have been in<x;ulated with it. We have seen a single 
vesicle on the finiier of the arm vaccinated in an infant, and in another 
infant, one on the chin ; and in one case, the vaccine vesicles so numerous 
about the neck of an infant as to form, as it were, a band of them 
encircling the part, nearly an inch in breadth. This infant had suffered 
from an erythematous affection of that part, which had produced some 
excoriation of the surface. A second instance of the same kind came to 
our knowledije afVir the vesieles had entirelv healed. In another case, 
a child eighteen months old, vaccinated a fortnight before, had well 
characterized vaccine vesicles on the external labia, and also on the 
perineum, and about the anus. The vo>icles bore some resemblance to 
certain forms of venereal eruption appearing about those parts in

«faildreii, and the case was carefully examiDed with reference to thii 

A very remarkable case haa been recently reported by Dr. R, 0. Clark 
^Lond. Med. Oaz,, Nov, 8, 1850), of "a genuine cow-pox vesicle rising 
•t (mother part Lbnn the point of insertion." A healthy looking child, 
nine months old, was vaocinat«d on the 28th of August, three JQcisiona 
being made over the deltoid muscle of the left arm. On the 30th, thera 
seemed a slight disposition to the formation of vesicles ; but all rednen 
diaappeared during the next day, and there were no other signs of iti 
faaving taken effect on that part. On the evening of the 2d of Septem- 
ber, the mother noticed a small red pimple about the middle of the fora- 
arin, which Dr. C. recognised the next day as presenting all the charac- 
ters of H cow pox vesicle uf aboat the third day afler vaccination, and 
which ran regularly through idl the stagea of such a veaele. He after- 
wards vaccinated the child at two different times with great care, with 
fresh mutter, but without any effect, so that the character of the vesicle 
may be considered as fully established. He referred the matter to Dr. 
Gregory for his opinion, who told him, that "if the single vesicle were 
feond Jide cow pox, the case was a very curcous one indeed, undoubt- 
edly the Grst of the kind that ever happened." Dr. G. recommended 
the tmt of re-vaccination, after some laxatives to the child, and himself 
«ent Dr. C matter for the purpose, which was used without effect Dr. 
G. stated that, although he hud before seen constitutional vesicles, be bad 
never seen them without tmeqaivoeal primary vesicle at the same time.] 

It is not uucommon to find the cbiltl's body covered, 
generally or partially, with a papulous eruption, of a 
lichenous character, from die ninth to the twelfth day, 
or even later. It is seldom seen in adult vaccination, 
bnt is frequent in children full of blood, iu whom 
numerous vesicles had been raised, which discharge 
freely. Vaccine lichen, as this eruption is properly 
called, often occasions great anxiety in the mind of 
the parent, from a suspicion that small pox is coming 
out. I have seen it in such intensity as to be fol- 
lowed by minute vesicles ; but this latter appearance 
b very rare. It is an accidental occurrence, chieflj 
attributable to the peculiar delicacy of the child's skin. 



248 ANOMALIES AND VARIETIES OF COW POX. 

and fulness of its habit. Like the constitutional irrita- 
tive fever, it indicates that the disease has taken effect 
on the system, but it is not deemed essential to the suc- 
cess uf the process. 

[Tn some cases, patches of roseola appear in the neigliboiliood of the 
place of insertion of the mntter, and extend more or less along the arm, 
gradually disjippearing as the areola fades. At other times, an er}*the- 
matoiis or raseolar redness covers the palms of the hands and soles of 
the feet alwiit the eighth to the tenth day, disappearing at the end of 
twenty -four or forty-eight hours, and requiring nothing but that its true 
character shall be recognised, so sis to give tlie necessary explanation to 
fipiends. Wo may add, that the lichen described by our author as 
accompanying certain ca«^es of vaccinia, may attend upon spurious as well 
as genuine vaccination, and hence cannot be regarded as any certain test 
of the efficacy of the operation.] 

The irregularities and anomalies of cow pox are 
various, and require to be specially described. The 
most singular variety of cmv pox is the petechial, or 
that, where from some peculiarity of habit, the vaccine 
poison (levolopes the hyemorrhagic diathesis. Of this I 
have only met with one instance, recorded in the Med. 
Chir. Trans, (vol. xxv.j).253). Petechijc, haemorrhages, 
and an ecchvmosed areola, were the characteristic 
featiu'es of this remarkable case. The child recovered, 
all luemorrhagic apj)carances having declined on the 

sixteenth dav of vaccination. 

./ 

[A nntice of this case may be found in the AfeJ. Chir. Rev., Jan., 
184:?. p. -JO.] 

The most common irregularity is that wherein the 
vesicle, at a very early period of its course, becomes 
prematurely red and itchy, whereby the infant is 
tempted to rub or scratch it. To this rubbing the sub- 
sequent ai)pearances arc usually attributed, but most 
unjustly, for the same consequences follow, though the 
child's hands arc mufiled. In this irregular form of 



VALUE OF TUE CICATRIX. 



vaccination, a small acuniinaled or conoidal puslvle will 
be perceived ou ihe sixth or seventh day, surrounded by 
a slight areola, of irregular shape. The contained fluid, 
instead of being a clear and transparent lymph, is 
opaque, and of a light straw color. The succeeding 
scab is small, and drops off prematurely. 

In some cases, the specific inflammation, or areola, 
proves very violent, extending from the shoulder to the 
elbow, and sometimes running into genuine erysipelas. 
The vesicle, instead of drying into a hard scab, is con- 
verted into an ulcer, discharging profusely, and leaving 
behind it a large scar, of the size of a common wafer, io 
which neither rays nor depressions can he traced. Much 
temporary inconvenience, but no permanent ill conse- 
quence results. The poison has taken full effect upon 
the causlilution upon the eighth day. All that happens 
afterwards is iintnaterial in respect to the security of the 
child. These facts will enable you to decide on the 
degree of importance to be attached to the cicatrix as 
an evidence of the perfection or imperfection of the 
original vaccine process. In every country, this is the 
test chiefly trusted to, for in the course of twenty or 
thirty years all memory of the actual appearances is 
iisuallv lost, and it is rare that any written record of 
ihcni is preserved. A perfect cicatrix, that is, small, 
circular, radiated, indented, and persistent through Ufe, 
is doubtless satisfactory proof that the individual pos- 
sessing it has passed through the regular cow pox, and 
has obtained from it all the protection which vaccina- 
tion is capable of affording ; but an imperfect cicatrix 
is no proof that such influence never had been felt, or 
that having been felt, it has subsided. Irregular cica- 
trices are coinpatihlc with full constitutional effect. 



250 ANOMALIES AND VARIETIES OF COW POX. 

because, as I have told you, they often depend upon 
irregularities commencing incidentally after the tenth 
day, when the specific influence has been completed. 
Even the total absence of cicatrix is not decisive 
against the present or prior existence of vaccine energy 
m the system ; for in many cases, the specific inflam- 
mation is moderate, and the resulting scar wears out in 
the progress of life, as other scars do, which are not the 
products of a specific poison. Perfect security is com- 
patible with a small and scarcely distinguishable cica- 
trix, with a large watery cicatrix, and with no cicatrix 
at all, at least none perceptible five years after the 
operation. 

[The committee appointed bj the Provinc. Med. and Surg. Associa- 
tion, in their report in July, 1830, say that, by itself, the cicatrix ought 
never to be absolutely trusted. They add, " we are inclined to believe 
that, though tlie presence uf a ]>erf<.'ct cicatrix is not a sure sign of pro- 
tection, it^ absence must be held to speak strongly against the existence 
of vaccine influence." 

Abundant evidence might be adduced, if necessary, derived from 
extensive observation in the Prussian, AVirtomberg, and l^avarian 
armies, as well as on a smaller scale in other places, to show that no 
dependence can be placed upon the vaccine scar as an evidence of pro- 
tection from an attack of variola. Indeed, it may be considered as an 
established point, that such is the case.] 

Another variety of cow pox exhibits, about the sixth 
or seventh day, the vesicle partially inflamed and scaly. 
A species of psoriasis has taken the place of areola. 
Whether these and similar anomalies are to be held as 
depriving the cow pock altogether of its specific anti- 
variolous property, is a question not }\?t decided. 
Jenner contended, that under such circumstances, no 
reliance could be placed on it in after Ufe; while on the 
otlier hand, Bousquet, a high authority, maintains tliat 



ANOMALIES AND VARIETIES OF COW FOX. 



in such cases, constitutional influence is by no means 
impaired. It is doubtful how far confidence can be 
placed in so defective a process as this. 

Cow pox is occasionally retarded in its normal pro- 
gress. That this should happen in consequence of the 
prior occupation of the system by measles or scarlatina, 
yon can readily understand. So likewise is it easy to see 
why this maybe the result of an accidental bowel com- 
plaint. But sometimes the cow pock vesicle, without 
any such cognisable cause, is retarded for three, four, 
or more days. Retardation of the vesicle does not , 
in any degree take from the ullimate security of the 
child. 

[Dr. Jenner enrly obsen-eJ that the presence of certain forms of I 
cutaneous disease, more especially the squainoiis and tlio veaicular, 
modified tbe progress of llie vaccine vesicle, and stated tliat vaccination 
performed on a skin occupied bj' any of these diseases " produceE every 
grwdatjon, from that slight deviation from perfection vrliich ia quite 
immaterial, up to that point which affords no security at all." 

The committee of the Provincial Medical and Surgical Aasoeiatioii | 
any, " Wherever there is the slightest diaturliance of vaccination mani- 
fested by a pre-existing cutaneous disease, the vaccination ought to be 
<listrusted, and repeated as soon as the ekin has been brought to t 
healthy stat«," — {Traniae. Frov. Med. and Surp. Aisoe., rol. viii ' 
p. 3].) I 

Mr. Slerry gives a case {Land. Med. Gtu:.,Apri\ 9, 1847) of Iha ' 
infiuenoe of lepra on vaccination, and says that he did not remember aa 
instance of succes>>ful and perfect vaccinatioa in a patient tlie subject of 
cutaneous disease. 

Dr. Bjron alao reports a cnse of interruption of vaccination by cuta- 
neous disease, and others might be quoted. i 

It is not, however, uniformly the case that the progress of the vaccine 
veeiele is Jnipeded by the previous existence of cutaneous disease.] 

Small pox and cow pox are sometimes seen running - 
their course simultaneously without mutual interference. 
At other times the cow pox is retarded. Occasionally

they mutually restrain and modify each other's action. 
Much depends on the time which has elapsed from 
the application of each germ respectively. As a gene- 
ral rule, it may further be stated, that extraneous fever, 
however excited, restrains the growth and modifies the 
normal progress of the vaccine vesicle. It never 
reaches perfection, unless the system be in a sound 
state. If, therefore, the variolous germ be received into 
the body quietly, and eliminate itself with little consti- 
tutional disturbance, vaccination may advance pari 
passu with the small pox, and complete its series of 
changes undisturbed. 

The following case strikingly illustrates this principle, 
and exemplifies at the same time the incubative period 
of small pox, and the law of exanthematic suspension : 
— William Bavin, fetatis 27, coachman, from 15 Cur- 
zon street, visited his brother on Friday, February 3, 
1813, whom he found laboring under small pox. He 
took the j)rccauti()n of being vaccinated on Monday, 
Fcbniary G ; began to feel poorly Saturday, February 
11 : obliged to leave off work, February 13. Eruption 
of small pox appeared on Wednesday, February 15, 
being the thirteen th day from exi)0sure to contagion. 
Scarcely any fever was present. The small pox proved 
distinct and mild, and ran a perfectly normal course. 
The vaccine vesicles were retarded, so tbat both dis- 
orders maturated togetiier. On Monday, February 20 
(the sixth day of variolous eruption, and the fourteenth 
of cow pox), the small pox pustules were well acumi- 
nated, and six vaccine vesicles were to be seen, full and 
finely developed. 

[The practical question of most interest connected witli the reciprocal 
influence of vaccinia and variola upon each other is, as to the latest

M. Legendre gives as his couclusioDs, from a comparison of GfLy-six 
obBen'atiuiis, derived from different Kiurces, that u')jile vai^cinatiun per- 
(bnned during the incubation of small pox, raodilita tlie cl>uruDl«r of 
that disease, the vaccine disease ilaelf ia usually modified in a degree 
directly pro|iortioBed to the shortness of the iritervsl between llie per- 
iormancB of the vaccination and the appearance of tlie small pox. The 
■Teoia is not so nell marked, and there ii no subcutaneous swell- 
ing. When vaccination is performed after tlie ap|iearaucf of variola, 
the vaccine vesicle sometimes ruus ila course, but does not modify ibe 
variola. 

Dr. Tardieu relates ft case {Jrckivtt ff^nA-, de Mid, 1815) of ft 
young man vaccinated after the pustules of variola had appeared. The 
pustulea reached the period of def^uamation by the sixth lo the eighth 
day, and tliere was no fuver nor awelling of the face and extremities. 
At the tenth day of eruption, the vaccine points had undergone no 
<^ange, but six days afterwards tht) jiatient atjited that for five daya 
put the vaccination scemtd lo have taken, and four vaccine ]iustules 
(the matter had been inserted in twelve or fifteen places in eai'h arm) 
were then seen on the right arm, almost entirely dried up. It would 
Mem from this as though vaccination is of s«rtice in those not vacd- 
sated, not only during the primary fever, but even at the commcucement 
of ihn variolous eruption. 

Dr. L. V. Bill (of Derry, N. II.) states that he has minutes of cases 
in vhich there was no evidence of vaccination liaving laken efil-'ct until 
after exposure for seven, nine, ten, and eleven days, to small pox in its 
meet malignant form, when the succeeding vartoluid was of the mildest 
diaracter. In these cases, hotrever, the patienta had been placed on a 
precautionary treatment and diet, and were usually vaccinated daily, 
onttl it was evident that the vaccine matter had talien. (Notice of his 
paper on Small Vox, Varioloid, and Vaccination — Aiiier. Juar. Mtd. 
Sei., May, 1830.)] 

Another vatiety of anomalnns, or what is called 
modified cow pox, presents ilsclf when the vaccine 
vims is reinserted ou the fourth, fifili, or sixth day from 
the primary vaccination. The result is, that the vesi- 
cles of ihe secondary vaccination form rajiidly, and are

hurried forward in their course, so as to overtake the 
first crop, when the whole maturate and scab together. 
The secondary vesicles are thus necessarily much 
smaller than the primary. Mr. Bryce, in 1802, inge- 
niously proposed to avail himself of this law, with the 
view of ascertaining whether the svstem was under the 
full influence of vaccination. The plan, though it 
never received the sanction of Dr. Jenner, has never- 
theless enjoyed great popularity, and is everywhere 
known by the name of Bnjce's test. He recommends 
that the second application of the virus should take 
place on the evening of the fifth or morning of the sixth 
day, so that the new vesicles may have fi'om thirty-six 
to forty-eight hours to grow, before constitutional or 
irritative fever is set up. Of late years, this procedure 
has fallen comparatively into disuse. In cases where 
the primary vaccination proves unsatisfactory, it is now 
more usual to recommend a repetition of the operation 
at the interval of one, two, or three years, according to 
the extent of the apparent imperfection. I believe this 
to be a great improvement on the plan of Mr. Bryce. 

Wiien re- vaccination is practised at distant periods 
from the primary insertion of the virus, the arm very 
generally presents the appearances of modified cow pox 
— that is, the vesicles advance with abnormal rapidity. 
Areola forms around them on the fourth or fifth day. 
Tiie resulting scabs arc small, and fall off in a few days. 
Much itching accompanies the process. In some 
cases, the renewed insertion of the virus occasions 
considerable local uneasiness, with more or le>s con- 
stitutional sympathy. I have seen re-vaccination in 
irritable habits occasion irregular and extensive areola, 
painful swelling of the absorbent glands, headache,

general weakness and lassitude, and a stroug dlsposltioa 
lo recurring erythema of llie arm. 



The surgery of vaccination, simple as it may appear 
to you, has nevertheless been a fruitful theme of con- 
troversy. Differences of opinion have existed with 
respect to the selection of lymph, the mode of making 
the incisions, and the number of incisions necessary to 
insure a full effect. Each of these points merits your 
attention. 

I. One of the earliest and most important disputes 
which chequered the career of vaccination (inasmuch 
as it led to the secession of Jenner, in 1807, from the 
original Jennerian Institution) had reference to the 
mode of taking the lymph. Dr. Walker adopted the 
plan of detaching the epidermis from the vesicle, and 
vaccinating with the lymph (or lluld) which exuded 
from (he abraded floor of the vesicle.* Jenner objected 
strongly to this, and employed only the superficial 
lymph. Dr. Walker persevered in his plan ; and it is 
but fair to confess that his vaccinations have stood the 
test of time fully as well as those conducted according 
to the Jennerian method. 

The proper time at which lymph may be taken so as 
to obtain it in the most efficient state for propagating 
the disease, has also been a subject of discussion. Some 
have objected to the employment of very early lymph, 
others have scruples in taking lymph after the first 
appearance of areola, and all parties have concurred in 
condemning the use of lymph taken on or after the 
tenth day. The facts bearing on this question are as

256 SELECTION OF EFFICIENT LYMfll. 

follows. The younger the lynipli is, the greater is its 
intensity. The lymph of a fifih-day vesicle, when it 
can he ohtaincd, never fails. It is, however, equally 
powerful up to the eighth day, at wMiich time it is also 
most abundant. After the formation of areola, the 
true specific matter of cow pox becomes mixed with 
variable proportions of serum, the result of common 
inflammation, and diluted lymph is always less effica- 
cious than the concentrated virus. Nevertheless, very 
pure lymph, if not too long humanized, will often prove 
effective when taken from the arm on the ninth, and 
even sometimes on the tenth day. After the tenth day, 
the lymph becomes mucilaginous, and scarcely fluid, in 
which state it is not at all to be depended on. Out of 
a dozen incisions made with such viscid lymph, not 
more than one will prove effective. The scabs of cow 
pox, ground to powder, and moistened with lukewarm 
water to the consistence of mucilage, will sometimes 
rc[)r()dnco the disease in all its purity, a sati.>factory 
proof that the alteration which the lymj)h undergoes in 
its progress to maturity is not of a sjiecific kind, liable 
to inflneiice the rrsult of the subsocjuont vaccination, 
but simply dilution. ExpcrimcMits with diluted lymph 
were formerlv made bv Dr. Adams, at the Small Pox 
Hospital, and have sincte b(»en repeated in France by 
M l>ous(jU(*t, and it is ascertained that effective vacci- 
nation may be thus |)roduced. 

Cow |)()x matter differs in its character and qualities, 
according to the source from which it has been obtained. 
Healthy and well Ivd children afford a lymph much 
superior to that which is obtained from weakly and ill 
fed children, whose blood is thin and poor. Lymph 
being a product of blood, it is obvious that the purer the 



SELECTION OP EFFICIENT LYMPH. 257 

blood, (he purer will be the lymph derived from it. 
But, further, experience teaches that the vesicles, even 
of apparently healthy children, are not equally fitted to 
reproduce the disease in purity. Some contain an 
acrimonious lymph which occasions irritable vesicles in 
all children, healtliy and unhealthy, vaccinated from it. 
Such vesicles are with difficulty distinguished, even by 
a practised eye. A good vesicle, too, may be drained 
so much that the exuding lymph possesses little or no 
intensity. Infantile lymph is more to be depended 
upon than the lymph obtained from aduhs. The mat- 
ter of primary vaccinations is more energetic tlian that 
of secondary vaccinations. These statements may 
serve as a guide to you in the selection of lymph where- 
with to vaccinate. 

[U is much to be fcnreii that sufficient attention has not heretofore 
been, and U not now always paid to the selection of good lymph, Ab 
well remarked by the committee of the Provinc. Med. and Surg. Associa- 
liao, " if a deviation commences, it may be perpetuated, and atTord a 
gradually decrcnaing protection ;" they add, " there is do doubt that 
lymph of this kiud bos been often used." 

The import«nce of the following rules laid down by that coraroitt«e, 
renders them worthy of transfer to our p^es : — 

" 1, The progress of the vesicle must bo noted at suitable periods, to 
learn tLat it passes through its stages regularly. 

" 2. Lymph should be taken from the fiflh to the eighth day, and be- 
fore the formation of tbe areola, a rule of Jenner, and which should 
always be observed. 

" 3. Lymph should never be taken from a vesicle which deviates in 
the least degree from the perfect standard, nor from a patient luboting 
under any cutaneous disease. 

"4, One or more vesicles should always be left to run their courae 
withotit being in any way disturbed. This ought always to be insisted 
npon. 

" 3. Whenever there is the slightest diiturbnnce of vaccination taani- 
fetted by a pre-existing cutaneous disease, vaccination ought to be dis- 



258 MODE OF OPERATION. 

trusted, and repeated as soon as the skin has been brought to a healthj 
stote." 

Dr. Waterhouse, in a letter to Dr. Mitchell, dated Cambridge, Sept 
20, 1801, says: "Yesterday I received a letter from Dr. Jenner, one 
paragraph of which I must transcribe, because it contains the golden rvle 
(^ vaccination^ viz. "I don't care what BriUsh laws the Americans dis- 
card, so that they stick to this — never to take the virus from a vaccine 
pustule for the purpose of inoculation^ after the efflorescence is formed 
around it, I wish this efflorescence to be considered as a sacred bound- 
ary, over which the lancet should never pass." {Med. Repository^ N. Y., 
Tol. V. p. 236.)] 

2. The second subject for oar consideration is the 
mode of making tlie incisions, so as to ensure the best 
and most certain results. Failure in the operation is 
always harassing to the friends, and is often made the 
pretext for delays dangerous to the child. Some sur- 
geons use a sharp, others prefer a blunt lancet Some 
consider it necessary to make the wound very superfi- 
cial, others go deeper, and arc careless whether much 
or little blood follows the iiiciiiion. A few operators 
scarify the skiu in numerous places, in preference to 
nraking incisions. I know very well that, provided the 
lympU be good, it matters little in what way the virus 
be applied, but the most uniforuily successful mode is 
the following. Let the lancet be exceedingly sharp. 
It should penetrate the corion to a consideral)le depth. 
The notion that the subsequent effusion of blood will 
wash out the virus, and thus di^feat our intention, is 
quite imaginary and groundless. Provided that a genu- 
ine lymph of due intensity has once come in contact 
with the abs()rl)ing surface of the cutis vera, the rest is 
immaterial. The vessels of the part have received the 
specific stimulus, and nothing can prevent the advance 
of the disorder but some constitutional cause. In

making the incision, the skin should be held perfectly 
tense between the forc6nger and thumb of the left hand. 
The lancet should be held in a slanting position, and 
the incision made from above downwards. 

3. The number of incisions which it is requisite to 
make, in order to produce a full constitutional effect, 
has been always a disputed point. At an early period 
of vaccination, one vesicle was held to be sufficient 
Then three, four, or six, were recommended. In Ger- 
many, great importance is attached to the raising of 
numerous vesicles, it being a received doctrine in that 
coantry, that unless some decided constitutional effect 
be produced, little reliance can be placed on the process 
as a security in after life. Common sense dictates that 
the greater the number of vesicles, the greater will be 
the local inflanmiation, the greater the probabiUty of 
constitutional sympathy, and on this theory the greater 
chance of ultimate security. Some of the German 
inoculators have been in the habit of raising from 
twenty to thirty vesicles in each subject. In forming a 
just judgment on this matter, the nature and quality of 
the lymph must always be taken into account, Lymph 
recently derived from the cow possesses so much inten- 
sity, and fixes itself with so much more of a poisonous 
character upon the skin of the arm than lymph long 
humanized or habituated to the human constitution, that 
a single incision made with it is equivalent to six or 
eight made with lymph of minor energy. 

I would recommend that whh lymph of ordinary 
intensity ftve vesicles should be raised, and that these 
should be at such distances from each other as not to 
become confluent in their advance to maturation.

report, ^ the insertion of the virus in three, or, at the most, four places, 
we believe to be quite sufficient This,'* they add, *^ nvill allow one or 
two of the vesicles to be opened for the abstraction of Ijniph, and the 
others to proceed in their regular and undisturbed course.*^ 

Dr. Heim thinks that twelve punctures are sufficient for vaccination 
of the young as well as for re-vaccination. He says that " too many 
punctures have been followed by severe local inflammation and gangrene, 
dangerous irritative fever, convulsions, and even death itself.** Among 
the Wirtemberg physicians, when only a single vesicle comes to perfec- 
tion, it is a very general practice to re-vaccinate. In this country, one 
vesicle is usually considered sufficient by practitioners, and even this is 
not always left undisturbed. 

"With this latter fact in view, it is a question of interest, and worthy 
of investigation, whether varioloid is of more frequent occurrence in this 
country than in those places where the virus is inserted in so many 
points at once. It is believed that only one vesicle was aimed at by 
Jenner, when ^he practice was first introduced.] 

Vaccine lymph should always be used in a fluid state, 
and direct from the arm, wherever practicable, for it is 
a very delicate secretion, and very slight changes in it 
arc capable of materially altering its quahties. Lymph 
which has been retained fluid for four or five davs, is 
very apt to occasion that irritable vesicle which I de- 
scribed to you as the most frequent of all the anomalous 
appearances. Dr. GiiUiver has lately been occupied in 
attempts to discover, by means of the microscope, what 
is the exact change which vaccine lymph undergoes by 
keeping, and which gives to it this noxious quality. 
His observations have not hitherto yielded any decisive 
results, but enough has appeared to warrant further and 
more extended inquiries. 

When lymph fresh from the arm cannot be obtained, 
other means must be had recourse to. Vaccine vims 
may be preserved fluid and effective for two or three 
days in small bottles, with projecting ground stoppers,

fitted to retain the matter. It may be preserved for a 
like time in small capillary tubes having a central bulb. 
This is the mode usually adopted in France for the 
transmission of vaccine lymph lo the provinces, and 
which proves very effectual; but if you attempt in tliis 
manner to transmit lymph to the East or West Indies, 
you fail utterly. 

Ivory points, carefully armed from vesicles possessing 
the true characters, are very effective. They should 
be used as soon as possible, for in the lapse of time the 
thin pellicle of dried lymph is liable to be rubbed off. 
With care, however, they will retain their activity in a 
cold climate for several weeks or even months, and 
they are found to be the most certaiu mode of sending 
lymph to oar colonies. Some practitioners prefer 
glasses to points, but they are less certain. The em- 
ployment of scabs for the propagation of cow pox was 
first recommended by Mr. Bryce, of Edinburgh, in 
1802. It is a very excellent mode of transmitting vac- 
cine matter to distant countries, but some nicety is 
required lu operating with scabs, which experience alone 
can teach.

Among the niany subjects of curiosity which the theory 
of vaccination opens, the chief interest now attaches to 
the doctrine that small pox and cow pox are diseases of 
the same nature — not simply analogous diseases (which 
all must be ready to admit), but identical diseases. 
When a child is vaccinated, therefore, he has, according 
to the supporters of this, the homophysic theory, received 
small pox a first time. If the child happens to take 
tlie ordinary casual small pox in after life, he is, accord- 
ing to the same theory, undergoing a second or recurrent 
attack of small pox. It is here assumed that cow pox 
and small pox are identical affections possessing a com- 
mon origin, and it is therefore argued that they must 
necessarily be governed, in their ultimate effects, by the 
same laws. It is a matter of considerable moment to 
determine on what grounds this opinion has been taken 
up, and to what objections it is fairly open. 

Dr. Jenner through Hfe adhered steadily to the notion 
which he had early imbibed, that cow pox and small

263 



pox were only modifications of each other. So strongly 
was this persuasiou impressed upon him, that in lua 
original essay he called cow pox variola vaccina. Bat 
he went even further. He entertained the idea, that 
cow pox was the original or parental form, which time 
and nnfavorahle circumstances had converted into the 
malignant variety of small pox. Jenner believed, there- 
fore, that in giving to man cow pox, he was in reality 
giving to him smalt, pox in its primitive and mildest 
form. Some of the followers of Jenner have adopted 
this fanciful notion. 

Diseases that mutually produce each other are clearly 
referrible to a common origin. Thus swine pox and 
small pox are the same diseases ; but cow pox and small 
pox are differently circumstanced. In man, no com- 
bination of circumstances, however unfavorable, has 
ever converted cow pox into small pox ; and no caro has 
ever succeeded in converting the small pox into the 
cow pox, although Dr. Adams, at one period of his life, 
flattered himself he had made approaches to that desira- 
ble consummation. 

But Dr. Baron and others have attempted to prove 
the identity of the two disorders, by reference to the 
history of epizootic maladies, and the frequent con- 
currence of a lues bovilja, or distemper in cattle, with 
variolous epidemics. Epizootics have often attracted 
public attention. In 1746 an act was passed to suppress, 
by strong preventive measures, the distemper among 
homed cattle. The fine for non-compliance was ten 
pounds. In 1757, another more stringent act fur the 
same purpose was passed, the penally being raised to 
fifty pounds. In 1769, a severe and fatal distemper of 
this kind ravaged England, and was considered of suffi-

cient importance to form part of the speech with wh 
King George the Third opened the parliament, Janua] 
9th, 1770. He recommends "this very important s 
ject to the immediate consideration of parHameiti 
Dr. Baron, in his " Life of Jeuner," (chapter 7,) iabi 
diligently to prove that this bovine disorder is a)Hed'| 
many of its features to small pox. " A beast," it is s 
"having once had tliis sickness, naturally or hy inoi 
lation, never has it a second time," 

A second argument brought forward to prove I 
common origin of small pox and cow pox, is dedaa 
from the alleged fact, that matter taken from the cow~ 
laboring under the malignant epizootic has produced 
in man, by inoculation, small pox. The experiments 
performed in India, in 1833, by Messrs. Furnel and 
£rown, which appear to hear out this assertion, are 
open to many sources of fallacy. 

It has further been argued, in support of the same 
theory, that we can, by making cows breathe an atmo- 
sphere impregnated with (he matter of human small pox, 
infect them with a pustular disorder attended wiih fever, 
the pustules so developed in the cow assuming the cha- 
racteristic appearances of cow pox, and being filled with 
a lymph exactly resembling that of the vaccine vesicle. 
These facts would he very decisive if they could he 
relied on, but no one in this country or iu India has yet 
been able to verify them. 

The pathologists who support the doctrine of identity 
have lately abandoned these views, and maintain that 
the principle is fully made out by the experiment of in- 
oculating the cow with variolous matter. Such an 
attempt was first made by Gassner. in 1807. and it was 
announced that the resulting vesicle yielded a lymph, 



IKOCUIATION OP THE COW. 



which, transplanted into the human body, produced 
cow pox. The subsequent experiments of Coleman, 
Sacco, Dr. Naylor, and of others made under my own 
eye at the Small Fox Hospital in 1828, threw a 
doubt over these statements, and they were generally 
discredited. 

In 1839, Mr, Ceely, of Aylesbury, decided the ques- 
tion, by showing, in a perfectly satisfactory manner, 
that by operating upon the mucous surfaces instead of 
the more insensible corion, the cow can be made with 
fecilily to receive the variolous poison, which tlie con- 
stitutlou of that animal converts into vaccine. These 
important experiments were instituted under the super- 
vision of the Provincial Medical and Surgical Associa- 
tion, in whose Transactions (vols. viii. and ix.) they 
are detailed at great length. Into the details of these 
experiments it is unnecessary to enter. No doubt can 
be entertained concerning tlieir correctness, which 
indeed the labors of some contincutal physicians, engaged 
nearly at the same lime in the same pursuit, have abun- 
dantly corroborated. The lymph thus obtained has 
been called the variolo-vaccine, to distinguish it from 
that which is obtained from the idiopathic affection 
of the animal. 

[Vt. J. C. Martyn, residing at the lime in tie town of Attleborough 
(UHsa,), claims as original the discovery that the cow cnn be variolated 
from small pox virus. On the 2 J of October, 1 835, bu inserted small 
pox mutter in one of the tcflis of b cow, making fourteen or fifteen 
punctures, one of which took, and was followed bj a regular pustule on 
the eighth and ninth dap. The matter from this, taken on the tenth 
day, he inserted in tlie arm of a boy, ten years old. This was followed 
by a regular vaccine vesicle, from which he vaccinated others, auouriling 
Id the whole to twenty-three. Ilia experiments cost him his practice, 
and he was obliged to remove to another state. The late Dr. John D. 
XuW, of Boston, gave him credit for these experimenls. 



EQUINE DRIGIK OF OOW POX. 



morbid secretion, is often observed to arise from con- 
tagion — that is, to originate in the application of the 
diseased secretion, thus idiopathicallj developed, to tlie 
teats of healthy cows, differently circumstanced, by the 
hands of tlie milker. I have already told you, that 
vaccine lymph from the arm of a child will, in hke 
manner, excite vaccine vesicles when applied to the 
teats, or the mucous surfaces of the cow, even though 
twenty years had elapsed since that lymph had been 
humanized or assimilated to the human constitution, 

3. A like morbid product, possessed of like proper- 
ties, may be developed in the teats of the cow, by tfae 
application to them of matter taken from the diseased 
heels of the horse. Dr. Jeuner was so deeply impressed 
with the importance of this principle in vaccine patho- 
logy, that he put it prominenily forward in his very first 
paper, and even contended at that lime, that the cow 
pox never appeared in cows, except %vhen they had, 
directly, or indirecily. access to horses. Dr. Jenner 
believed that this affection of the heel of the horse was 
that commonly called by farriers the grease. Attempts 
have been made of late years to throw discredit on this 
supposed origin of vaccinia. Some have doubled the 
facts altogether. Others, as Dr. Baron and Mr. Ceely, 
aver, that the affection is not the pure grease, but a 
disorder allied to it, Tiic name of the disease is a point 
of little importance. The experiments of Dr. Loy, Dr. 
Sacco, and many others, have satisfactorily shown not 
only that vaccine vesicles may be produced in the cow 
hy matter originally supplied by the horse, hut that the 
secretions from the horse's heel may be applied directly 
to ihe arm of the child, and will produce these vesicles 
in all respects identical with those of the true vaccine. 



VABIOLOUB OBIQIN OP COW POX. 



Dr. Baron himself acknowledges that "in his views on 
the cunnexioQ of vaccine with equine disease, once 
considered as a wild speculation. Dr. Jenner proceeded 
with his usual caution and discretion."

4. To these three modes, so long known, of exciting 
vaccinia in the cow, the labors of Mr. Ceely liave now 
added a fourth. He has proved that the matter of 
human small pox will excite the vessels of the cow's 
teat or vaginal membrane to the production of a fluid or 
humor, identical in all its properties with that which 
arises from febrile disturbance in the cow's system, from 
contagion, and from the matter of grease, or some alUed 
disorder of the horse. 

To conclude, however, from these experiments, that 
cow pox is small pox in a modified form, it should be 
shown, 1st, that the febrile disturbance of the cow is of 
the nature of variola; and 2d, that the affection of the 
horse's heel is also variolous. Dr. Baron and Mr. Ceel), 
sensible of this, have attempted to prove both these 
points, but, in my opinion, have signally failed in each 
instance. The variolous character of the equine affec- 
tion appears to be entirely gratuitous, and I have else- 
where given my reasons for thinking that the lues 
bovilla is more nearly allied to scarlatina than to variola. 
In truth, it is neither the one nor the other, but an 
affection siii generis. 

I would rather deduce from these experiments and 
observations, the conclusion at which Mr. Greaser, 'of 



271 



natB AQAIttflT IDBNTtTT. 



Bath, arrived, in January, 1801* — viz. "that a morbid 
poison applied to different animals produces, not a simi- 
lar and specific disease, but the disease to which the 
animal, from constitution and stmclure, is predisposed." 
Equine matter, long humanized vaccine lymph, varioloas 
matter — each, when applied to the vessels of the cow, 
developes vaccinia. The constitution of the cow con- 
verts tlie variolous and (he equine miasm into the vaccine 
miasm, in the same way as the vaccine fluid is secreted 
under several forms of feverish excitemeuL 

Other facts might be mentioned which militate agRiost 
(he theory of identity. If, for instance, a child is 
inoculated for smalt pox some days after exposure to 
casual infection, the diseases, locally and constitutionally 
excited, coalesce, and unite in producing one etTecl on 
the body. But if a child be vaccinaled some days after 
exposure to variolous infection, the two dbeases do not 
coalesce or hybridize. Each preserves its separate and 
specific character. In October, 1800, this actually hap- 
pened at the Small Fox Hospital. A child, wlio had 
been exposed to the infection of small pox, was vacci- 
nated. Both diseases advanced. A lancet charged 
with lymph from the vaccine vesicle produced cow pox. 
Another lancet charged with matter from a variolous 
pustulc,_/ormp</ within the vaccine areola, communicated 
small pox.f If the diseases were truly identical, and of 
the Srime intimate nature, it is incredible that tliis dis- 
crepancy of residt should have been observed.

On all these grounds I demiir to the theory of 
identity, and bold that smalt pox aud cow pox are 
antagonist affections — that cow pox, instead of being, 
as Dr. Baron maintains, of a variolous, is, in fact, of aa 
anti-vario/ous nature — that it alters and modifies the 
human constitution so as to render some individuals 
wholly, others partially, aud for a time, unsusceplihle of 
small pox. Cow pox and small pox may be viewed as 
opposing powers, striving to gain the mastery of the 
human frame, and each, under different circumstances, 
and at different times, proving successful. I'he con- 
clusion to which M. Bousquet (Traife de la Vaccine, 
page xvi.) has come appears to me to be the just 
one. " La vaccine," says this acute writer, " et la 
variole ne sont pas la meme chose. Mais si elles dif- 
f<lrent dans leur origiue, daus leur principc, elles se 
rapplecnt mcrvcilleusement dans leiirs effects. II vty a 
pas entre elles identity dc nature, niais il y a reciprocity 
d'action." To my mind, nothing can be more satisfac- 
tory than such a conclusion. ^ 

I have gone into this detail, because the doctrine of 
identity is now very generally received throughout this 
country, and I cannot but think it has been hastily 
adopted. The difiiculties into which such a dociriuo 
leads us will be made very mauii'est %vhen we have 
investigated tlie facts regarding post-vaccine small 
pox.

ratio, establishes, as the committee remark, a most remarkable analogy 
between these diseases. 

The committee of tlie French Academy on Vaccination for 1843 (M. 
Gastel reporter) say, that if they are not identical in their nature, there 
is at least a great analogy between them, and give reasons for this 
opinion. 

Since the decisive experiments of Mr. Cecly, whose successful inocula- 
tion of the cow with small pox matter is now so well known, the 
advocates of the identity of the two diseases have been very much 
strengthened in their opinion, and are doubtless in the majority. 

Dr. Alex. Knox considers the question as settled, and remarks that 
the *' identity supplies a powerful argument in favor of vaccination ; bo 
much so,'' he adds, ^ that a conviction of the non-identity of the two 
diseases would go far to shake, in toto^ our belief in the real efficacy of 
vaccination." (Lond, Jour, Afed., Nov., 1 850.) 

At the same time, it would seem yet to be an open question, but not 
one of sufficiently practical importance to call for more space than has 
been already devoted to it] 

When we were engaged in tracing the early history 
of vaccination, you must have been struck with the 
extraordinary contrast between the absolute scepticism 
concerning the prophylactic virtue of cow pox which 
p^vailed before the publication of Jcnner*s first essay, 
and the unlimited confidence reposed in it, within two 
years afterwards, in all parts of the world. A cahii and 
dispassionate examination of .Tenner's first essay, is cal- 
culated to awaken some surprise at this sudden conver- 
sion of men's minds. The equine origin of cow pox 
which the work begins by pronmlgating, was mere 
theory, which time has since greatly modified. The 
identity of small pox and cow pox, also put promi- 
nently forward, was at that time a doctrine unsupported 
by any direct experiments. The cases of successful 
result which the work recorded were few in number 
(twenty-three in all — viz. sixteen of the casual, and 
seven of the inoculated disease), and the doctrine of 



) 



EARLY VIEWS OF JENNEE. 273 

permanent security was deduced from casual causes 
alone. It is singular tliat in tliis first essay no mention 
is made of any instances in which tlie cow pox failed 
to afford protection in after life, though, as I stated to 
you, such occurrences had frequently been pressed upon 
Jenner's attention. It was not until the year 1800, 
and in his third publication, that any allusioo to 
them is to be found. It ran in these words — " Some 
there are who suppose that the security from the small 
pox obtained through the cow pox will be of a tempo- 
rary nature only. This supposition is refuted, not only 
by analogy with tlic habits of diseases of a similar 
nature, but by incoatrovertible facts, which appear ia 
great numbers against it."* In his uriginal essay, Dr. 
Jenner does not propose the abandonment of inocula- 
tion, nor does be allude to the possible e.\ternunation of 
small pox by tlie general adoption of vaccination, hut 
he suggests the probabiUty of its usefulness to four 
classes of persons: — 1. to those who from family pre- 
disposition may be presumed liable to take small pox 
severely ; 2. to those constitutionally predisposed 
to scrofula ; 3. to those who from peculiarity of habit 
resist small pox inoculation iu after life ; 4. to those 
who may labor under some chronic ailment in wiiich 
counter-irritation is desirable, I have shown you that 
it was an individual belonging to this fourth class, who 
was selected by Mr. Cline at this hospital, as the sub- 
ject of the first experiment in London. 

It was not long before Jenner threw off that reserve 
with respect to the powers of cow pox manifested iu his 
first publication. He confidently stated that the security

VARIOLOUS EPIDEMICS. 



afforded by cow pox was as complete and as permanent 
as that afforded by once undergoing tbe disease ; and 
in May, 1801, within three years from the first an- 
nouncement of his discovery, he writes thus ; — " It is 
now too manifest to admit of controversy, that the anni- 
hilation of small pox, the most drcadfnl scourge of the 
hnman species, must be the final result of this practice." 
The popular voice went fully with Dr. Jenner in these 
pleasing, but illusory anticipations. After ten years of 
almost uninterrupted prosperity, however, the course 
of vaccination began to be slightly clouded. In the 
year 1809, Mr. Brown, of Musselburgh, published an 
inquiry into the anti-variolous power of vaccination, in 
which he broached ^e opinion, that its virtue dimi- 
nished as the distance from the period of vaccination 
increased. His statements, however, were vague, and 
made no impression upon the public mind. 

In the year 1818-19, an epidemic small pox per- 
vaded Scotland, the first that had occurred in these 
countries since the great epidemic of 1796. During 
this epidemic, many vaccinated persons passed through 
a mild form of small pox. About this period the term 
modified small pox was introduced, and generally 
adopted. Dr. Monro, of Edinburgh, and Dr. Thomson, 
detailed the chief events of these epidemics, and though 
much discussion arose, the general confidence in vacci- 
nation was in no degree shaken. In 1824, small pox, 
after being in abeyance fourteen years, prevailed epi- 
demically in Sweden, and attacked a considerable 
number of vaccinated persons. The total mortality 
amounted to 560, of whom 103 had undergone vacci- 
nation, 69 bearing good marks, and 34 less perfect 
evidences of the vaccine process. Of the 560 deaths,

391 were infants aud childreo (below the age of 15) 
— lOy were adults. In 1825, this epidemic visited 
London, a great increase in the deaths by small pox 
appeared in the bills of mortality, and many persons 
vaccinated in early Hfe took the disease. In 1826-27, 
France suffered from an extension of the same epidemic, 
which fell with great severity on the population of 
Marseilles. Many vaccinated persons went through the 
modified disease. In 1829, the same epidemic invaded 
the north of Italy, and was particularly severe at Turin. 
In the same year, the governments of Germany, who 
always encouraged and even enforced vaccination, see- 
ing the steady advance of the disease towards them, 
took alarm; and then began that practice of re-vacci- 
nation which has formed so striking a feature in the 
medical history of the German states for the last twelve 
years, It commenced in the royal armies of Wirtem- 
berg. Then succeeded the re-vaccination of the Prus- 
sian, Danish, and Baden armies. 

In 1835, the government of Wirtemberg, satisfied 
with the results of the military trials, extended the 
plan, aud ordered the re- vaccination of the entire civil 
population of the kingdom. In the meantime, however, 
small pox had made considerable ravages in the country. 
We le^firn from Dr, Heim's elaborate work, that in the 
five years from 1831 to 1836, there were attacked by 
small pox in Wirtemberg J677 persons, of whom 198 
died. 1055 had been vaccinated, 75 of whom perished 
— 622 had never been vaccinated, and of them 123 
died. The population of Wirtemberg is estimated at 
rather more than a million and a half of souls 
(1,587,438). 



276 



VARIOLOUS EPIDEMICS. 



Ceylon was the British colony where tlic govemiiieni 
earliest interfered and most energetically encouraged 
the practice of vaccination. Salaried vaccinators were 
scattered over the whole island. So successful were 
their labors, that up to the beginning of 1819, it bad 
often been said that tlie experiment of exterminating 
small pox had been made and successfully carried out 
in Ceylon. In July, 1819, however, a severe epidemic 
small pox broke out there. In 1830, a second epidemic 
overspread the island — in 1833, a third, and in 1836 a 
fourth. In these four epidemics, 12,657 persons were 
attacked, of whom 4090 died, being at the rate of 
thirty-three per cent, or one out of every three, — prov- 
ing that small pox had lost nothing of its malignity 
during its period of quiescence. 

It is true that the largest proportion of the persons 
so attacked had never been vaccinated, hut in each of 
the epidemics a certain number of vaccinated persons 
took small pox. The proportion of the vaccinated to 
the unprotected varied. In the third epidemic, out of 
a total of 460 attacked, 341 represented themselves as 
vaccinated. 

Denmark has undergone several visitations of epi- 
demic small pox ; yet in no country in Europe has 
more attention been paid to the practice of vaccinarion, 
both as respects the numbers submitted to the process, 
and the purity of the lymph employed. 

The first was in 1824, the second in 1826, die third 
in 1829. Copenhagen suffered also in the years 1833 
and 1835. 

England experienced the second epidemic visitation 
of this century in the year 183S, and again many vac-

cinated persons (or persons believing themselves to 
have been vaccinated, and trusting to it as their 
security) suffered attacks of the prevaihng malady. 

This epidemic commenced in the summer of 1837, 
and did not finally terminate til! Deceuiher, 1839. The 
total deaths throughout England and Whales during 
that period (two years and a half) by small pox, 
amounted to 30,819, or an average of 12,200 deaths 
per aanuni. Calculating that the rate of mortality ruled 
aboat twenty or twenty-five per cent, it follows that in 
those thirty months there occurred in England and Wales 
not fewer than one hundred and fifty-four thousand 
cases of small pox. In 1844-45, another severe epi- 
demic invaded London, commencing April 21, 1844, 
and terminating May 25, 1845. Nearly at the same 
period, small pox appeared as an epidemic at Calcutta. 

After this imperfect sketch of the reappearance of 
small pox both in Europe and Asia, since the lull which 
succeeded the first introduction of vaccination, I shall 
proceed to state to you the results which statistical 
researches have given, as to the relative numbers and 
ages of the vaccinated who have been attacked by 
small pox, and the ratio at which small pox succeeding 
to vaccination has proved fatal in this and other 
countries. 

I shall begin by stating the results of the experience 
at the Small Pox Hospital, and shall then contrast them 
with the recorded experience of other countries and 
other establishments. 

The following table was preseutcd hy me to a com- 
mittee of the House of Conunons which sat, in 1832, 
to consider the expediency of continuing the Vaccine 
Board.

These statements and tables are amply sufiGcient to 
sho%v how large a proportion of those who, in Europe, 
at the present time, contract small pox, have undergone 
vaccination in early life. They cannot be perused 
without the conviction, that some material error had 
crept into the views orighially entertained regarding 
the power and capabiUties of tlie vaccine inoculation. 



282 



AGES OF PERSONS ATTACKED 



If small pox can invade so large a proportion of a well 
vaccinated population, as tlie last table exhibits, it is 
obvious, that all idea of banishing that disease from the 
earth is vain and illusory. It is equally manifest, thai 
any attempt to institute a parallel between cases of 
small pox after vaccination, and cases of secondary or 
recurrent small pox, nuist fail. The most credulous on 
this point may search far and wide, before he finds in 
the records of the last century any counterpart to the 
facts which these five Danish epidemics display. 

The interval between the primary vaccination and 
the attack of small pox fluctuated in inost of the pre- 
ceding instances between seven and thirty years. By 
far the larger proportion of the cases consisted of adults 
in the vigor of Ufe. The following table exhibits the 
ages of those who were admitted into the Small Pox 
Hospital, having small pox after vaccination, during the 
epidemic of 1838.

From this it will be seen that between the ages of 
twenty and twenty-five, the disposition in tbe vaccinated 
to take small pox is at its maxim am.

' These tables correspond so closely with each other, 
and with the experience of the Small Pox Hospital 
already given, that you may rest assured they indicate 
some law of the animal economy. In each instance, 
you perceive, llie maximum of cases occurs at the 
period which immediately follows puberty. It is there- 
fore rendered more than probable that some modifica- 
tion of the system takes place at that eventful epoch of 
human life which lessens the protective power that 
vaccination had previously exerted, I have already 
made you acquainted with the fact, that in very early 
times an impression prevailed that the protective power 
of cow pox did- deteriorate in the course of time, and 
that Jcnner was very unwilling to give credit to it. It 
is a matter of general notoriety that small pox is very 
seldom taken by vaccinated children who are under

the age of eight years. In the course of a long expe- 
rience at the Small Fox Hospital, I have never seen 
F more than three or four instances of such an occur- 
I rence. The protective power of cow pox may there- 
I fore, for aJI practical purposes, be considered z.s cmnplete 
I for that period ; but we are compelled to confess that 
later in life it diminishes in a certain proportion <rf j 
cases. What the exact proportion is, never has beail 
ascertained, and, for very obvious reasoDS, never can boj

of COW pox will improve pathology far more llian a 
blind adherence to the doctrine of its unvarying pro- 
phylactic virtue. 

The preceding tables, while they certainly counte- ' 
nance the notion of diminished vaccine energy through 
the medium of those changes which time effects in the 
frame, prove at the same time, most incontestably, that 
a portion of virtue still clings about the system sufficient , 
to preserve life, though not to exhaust susceptibility. .| 
To determine with accuracy the average ratio of mor- 
tahty which obtains when small pox invades those who 
have been well vaccmated, is a point which the statisti- 
cal records of the last twenty years teach us with 
considerable precision. You will remember that small 
pox in former times (and among the unprotected in 
recent times) proved fatal at the rate of twenty-five, or 
from thai to thirty-three per cent, (one out of four, or 
one out of three).

The previous table, compiled from various sources, 
will show how great is the diminutiou in the ordinary 
rate of mortality by small pox when vaccination has 
preceded. It will be seen that the average rate is 
ttien six per cent., the maximum being thirteen and 
the minimum two. 

The result of these statistical investigations may be 
stated to you in a few words. Small pox in the un- 
vacciuated is five times more fatal than it is to those 
who have previously undergone vaccination. The fol- 
lowing table, carefully drawn up from the records of the 
Small Pox Hospital for the year 1841, shows you how 
this is effected. It is an analysis of the several cases 
admitted in that year, having small pox after vaccina- 
tion. It will be seen that nearly two thirds of the 
cases (or GO per cent.) received the disease in a modi- 
fied form. The remainder (-10 per cent.) received it 
in a normal form, but in variable degrees of intensity, 
the mortality among them following the ordinary law.

remain eight deaths. Now supposing that these 151 
persons had never heen vaccinated, the mortality would 
have been at least five times eight, or forty, and might, 
under unfavorable circumstances, have reached fifty. 
Such appears to be the actual amount of the protection 
which vaccination affords, and with it, such as it is, we 
must, I believe, rest satisfied. My firm persuasion is, 
that no additional precautions on the part of vaccina- 
tors, and no alteration in the kind of lymph employed, 
will have the slightest effect on the general results. 
But the world are not so easily persuaded to rest upou 
their oars, They have been taught to believe that 
vaccination was an almost certain preventive of small 
pox, and they are loath to see it shorn of its original 
splendor. A restlessness and dissatisfaction, indeed, in 
regard to tlie amount of vaccine protection, have been 
perceptible throughout Europe for many years, and 
two expedients have been largely practised, with the 
view of increasing the security of the vaccinated. One 
of these is the employment of lymph recently derived 
from the cow ; the other is re- vaccination. A few 
observations on each of lliese topics will conclude my 
account of cow pox. 

[For remarks on the mortalily of small pox after vawination, see 
Appendix L.] 

An impression that vaccine virus decaj-s in power, 
in proportion to the number of times that it makes the 
circuit of the human body, has long prevailed. In all 
parts of the Continent, and recently in England also, it 
has led to the frequent trials of lymph fresh from the 
cow. Jenner did not object to occasional renewals of 
the stock of lymph, but it does not appear that he ever 
acknowledged deterioration of the virus by use as a 



288 



FREQUENT RENEWAL OF LYUPH. 



common occurreuce, or as a source of failure. In 
1829, the invasion of epidemic small pox induced the 
Sardinian govemmeiil to try a variety of new stocks of 
[yniph. We are informed by Dr. Griva, chief of the 
vaccine establisbment at Turin, that no perceptible 
difference was to be traced between tlie aspect and 
progress of the old and of the new lymph. lu Wir- 
temberg, between 1S31 and 1836, forty new varieties 
of lymph were tried, but without any obvious advan- 
tages. In other parts of Germany, the same trials were 
made. In France, a new variety of lymph, obtained 
from the dairies of Passy, near Paris, was brought into 
use by M. Bousquet in 1836, and it certainly proved 
much more energetic in its primary effects than thai 
which had previously been employed. About the same 
period, we changed our stock of lymph at the Small 
pox Hospital, and with decided advantage. There are 
occasions, therefore, when I should be disposed to 
recommend the measure, but it is not lightly to be 
resorted to. Helm calculates that three fourths of the 
inoculations made with lymph direct from the cow fail 
altogether of effect. When they do take effect, it often 
happens that severe local inflammation is excited, pro- 
ducing irritable sores and glandular sweUings. Nor are 
we at ail sure that the ultimate effect, the security of 
the patient in after life, wilt be sensibly augmented. 

[Some (liffereace of opiiiion seems to exist as to Lhe necessity of 
resorting to tho cow for supplies of fresh lymph. The Committee of 
the Proiincial Med. Htid Surg. AssociatioD conclude that it does not 
necessarily become deteriorated, though it may huve passed through a 
great Dumber of subjects, and have been used for a great number of 

M. Fiard, however, infers from the reault of hi« experimentB with tin 
vncdne mttUer of 1830 and 1844, that it baa decreased in efficacy, and

hence concludes, that it should be procured fresh from the cow every 
fire or six years. (VAbfU/e M6i., Nov., 1844, p. 26i.) 

M. Castel Bays (Report of Comuiittee on Vaccinalion of FrcDch 
Academy for 1843), thnt nbstever may be the opiaion of practidoaers 
on this controverted qucstiou, it in an act of prudence to permit no 
opportunity to escape of renewing tlie vaccine virus. 

Mr.Steinbrennersays(7Vairf <fe^ ForctRe, Paris, 1846) tliat "vHccine 
virus does undergo a positive deterioration by transmission througb suo- 
oesuve individuals, and that il is tJierefore desirobla to obtain fresli lymph 
from the cow frequently, nliidi may be done by taking il annually," 

The Committee of the French Academy which reported in 1845, 
also recommended, as a prudential measure, the frequent rvnewsl of 
vaccine lymph, and resorting to the cow for this purpose.] 

And now as touching re-vaccination. It is believed 
bj many that vaccine protection may be renewed, as 
we renew the lease of a house, every seven, fourteen, 
and twenty-one years. By the physicians of Germany, 
re-vaccination has been held up as a measure scarcely 
less Important in its efTects, nor less widely applicable, 
than primary vaccination, Tn France, on the other 
hand, the repetition of the vaccine process has been 
disparaged. A commission, expressly nominated to 
investigate the matter, comprising some of the most 
talented men in Paris, reported against re- vaccination. 

The question is not easily decided for want of data, 
which, in the very nature of things, can never be sup- 
plied so as to insure a satisfactory result. Happily, 
there is no occasion to press the cause to judgment 
The operation, except in a few rare instances, is pro- 
ductive only of slight and temporary inconvenience, 
and may safely be reconmicnded. 

If the resulting vesicles prove good, and the course 
of the disorder normal, you have good grounds for 
congratulating the patient upon the success of your 
measure. In the larger number of instances, however. 



290 RE-VACCINATION. 

this will not happen. The vesicles will be small, the 
areola irregular, and the benefit scarcely appreciable. 

In a few cases, the process of re-vaccination occa- 
sions considerable local distress, and some amount of 
constitutional disturbance. I have seen extensive ery- 
thema of the arm follow re-vaccination. DeUcate 
young women of scrofulous habit of body are liable to 
sufier in this way. It is the chief drawback to the 
general adoption of re-vaccination in adult life. 

The imperfect aid afforded by re-vaccination suggests 
the question whether, in adult inoculation (between 
the ages of twelve and twenty), we might not find a 
better mode of testing and improving the security of 
tlie vaccinated. Small pox, taken casually after vacci- 
nation, proves fatal, as we have seen, at the rate of 
seven per cent. Inoculated small pox proved fatal, in 
former times, at the rate of only one fifth per cent, or 
one iu five hundred. As regards the extension of small 
pox from the practice of inoculation, no real danger 
need be apprehended. The experience of ten years in 
England has amply demonstrated that the difinsion of 
small pox is wholly independent of such artificial j)ro- 
pagation. Small pox has been as general in England 
since inoculation was abolished as it was previously. 
But it is as yet little known, that small pox may be 
received into and pass through the system without pro- 
ducing either fever or eruption. I inoculated three of 
my own children at the respective ages of twelve, 
thirteen, and fourteen, after successful vaccination in 
infancy, and the result was as follows : — In two, local 
affection without any fever or eruption. In the third 
case, local affection without fever, but with papular 
eruption on the seventli day, not advancing to vesicles. 



RE-VACCINATION. 291 

I firmly believe that these children are now, and will 
remain through life, unsusceptible of smaU pox. The 
advantages derivable from such a course of procedure 
are these : — If the child's constitution be under the full 
vaccine influence, no effect will follow. If the vaccine 
influence be subsiding or altogether lost, then the small 
pox will be taken at the period of Ufe (puberty) most 
favorable for safety, instead of being received (as too 
often happens under the present system) under circum- 
stances the most unfavorable, — for instance, by mothers 
at the period of parturition, by young women on the 
eve of marriage, or by young men at a distance from 
their friends. The state of the law in England pro- 
hibits the practice here ; but I hope it will be tried in 
other countries, where the judgments of medical men 
are less fettered. 

[For remarks on Re-vaccination, see Appendix M.] 



294 HISTORY OF VARICELLA. 

occurs in medical history until the year 1767, when Dr. 
Heberben, in the first volume of the Transactions, pub- 
lished by the Royal College of Physicians in London, 
entered fully into the tlieory and diagnosis of varicella. 
He adopted the notion, hitlierto unavowed by any 
medical author, that variola and varicella are different 
diseases. He brings forward very strong arguments in 
(avor of this doctrine. His paper is long, and appa- 
rently drawn up with great care and attention. But 
Hoberden falls into many errors, and was obviously 
ignorant of some essential facts bearing upon the patho- 
logy of varicella. He merits our applause, however, 
for having first distinguished varicella as the offspring 
of a specific poison. The strange thing is that, with 
this impression so strong on his mind, he should still 
have calleil the disease variola pusilltB. It had been 
named varicella three years before, by Vogel, in Ger- 
main. The term varieella does not occur in Sauvages' 
" Nosv^loi^v," published in ITl^S. His synonyms are 
" wattT poek, petite verole volaute. verolette, variolae 
lvmphutiou\ varii^he volatiea\" We mav be sure from 
this that the term varieella did not come into general 
use until after 1 770. 

lleberdeu's memoir on chieken pox was long con- 
siilered as the standard work on the disease. The 
prineipal authors on a arieella in the present century are. 
Frank, of Vienna, who wrote on it in ISOo. under the 
title iM* reninhiirus Variolodes V» sieulosus : Willan, in 
ISi'o. who has a ehaprer devoted to varicella in his 
wvM-k on •• Vaeelue Inoeulation ;" Pr. Helm, of Kerlin. 
lSOi>. a notiee ol* whose work is to he found in Cross's 
" Aeeouut of the Variolous Epidemic of Xonvieh:" 
Pr. Mohl. of Copenhagen ^1:^17', whose treatise is 



DETAIL or ITS STHPTOHS. 



295 



entitled " Dc Varioloidibus et Varicellis ;" and lastly, 
Dr. Thomson, of Edinburgh, who wrote on it in 1820, 
and revived the exploded doctrine of its identity with 
small pox. 

And now I must give you a brief descriplion of this 
disease, the true, vesicular, lymphatic varicella — the 
hastard, flying, lymphatic, crystalline, or imperfect 
variola of some authors. The defiuitiou of varicella is 
as follows : — " A slight disorder, the offspring of a spe- 
cific miasm, which, without initiatory fever, throws out 
an eruption of vesicles, sometimes distinct, sometimes 
confluent, which maturate in three days, and desiccate 
into granular scabs, which speedily fall off Little or 
ao fever accompanies the maturative stage, and no 
secondary fever follows. The disorder chiefly prevails 
among children, and occurs but once in life." 

Varicella has a very short incubation, not exceeding, 
as I believe, four days, certainly less than a week. Dr. 
Heberden, in his Commentaries, mentions the case of 
a lady whose two boys had varicella. On the eighth 
or ninth day from the maturity of the vesicles, the 
mother sickened for tlie same malady. He then 
inquires whether this is the usual period of incubation. 
This incubative period is always, so far as I have seen, 
siknt, and so say Heberden, Plenck, and Bryce ; but 
Dr. Willan, who is entitled to attention, says there are 
often present, for one, two, or tliree days prior to the 
eruption of varicella, languor, somnolency, a furred 
tongue, a hot skin, a quick pulse, with some sore throat 
and rheumatic pains. I cannot reconcile these state- 
ments of Willan with the results of my own expe- 
rience. 

[In an epidemic of variccllii hi the Hospital Neclter (Puris) id 




S96 PS0GRE8S OF THE ERUPTION 

1643—14, accurately described by M. Deli>ecli, ha fixed tbe tnculxi 
period at twelve dnp.] 

The first thing I ever observe in varicella is the 
eruptiou of vesicles, of the size of a split pea, being 
simple elevations of tbe cuticle, or minute blisters, pre- 
senting the appearance of the skin having been exposed 
to a shower of boiling water. The parts chiefly occu- 
pied by the eruption are the back and scalp. Tbe face 
is not so universally the seat of eruption, as happens in 
small pox. Nevertheless, at times, ibe face is exten- 
sively occupied. The vesicles vary in shape. Dr. 
Willan, who loved minuteness, wishes to distinguish 
three kinds — the lenticular, conoidal, and globaie. I 
cannot see these distinctions myself, and therefore I 
will not attempt to teach them to you. The vesicles 
are surrounded by a superficial and narrow areola. 
They appear in successive crops for two or three days. 
Wliile the new vesicles are forming, the old ones shrivel 
and dry up. 

[Careful exainination will show that the vesicles in varicella do pn- 
Bcut tlieie three varieties of furin pointed out by Dr. Willan, and 
admitted by later writei's ; but they may all be found in the Mine 
indiridiiol at the same time, and therefore the difltinction is of no impor- 
tAnce in a jtraclical point of view. 

The vesiclea are sonK^iaines preceded by small, pale, roee-colored 
spole, with little or no elevatiou, the color of which disapjiearG under 
pressure of the finger, vliich are soon followed by elevations of the 
epidermis. Tlie occurrence of auch spots has been denied by some, 
but they have been pointed out by Ilatl^, and were psrticnUrly noticed 
by M. Trousseau during an epidemic of varicella at the Ilospital Necker 
(Fans), in 1843 and 1844. 

Souietiincs, also, the vesicles enlarge to such an extent as (o resem- 
ble true bullse of pemphigus. We have known the bulhe reach tlia 
size of half a dollar, and even of a dollar ; and in one cas«. the excoria- 
tioua left by several bullie wliicli had been rubbed, extended for 6vo

or sijc inches on the upper part of the back, iu an infant eij^ht montlis 
and a hair old.] 

On puiicturitig the vesicles, a clear Ij'mph, scarcely at 
all mucilaginous, escapes, and the cuticle falls to the 
level of the surrounding skin. There is no tumor, no 
varus. If the vesicle remain unbroken for twenty-four 
hours, the contained fluid becomes slightly opacjue. 
They are very itchy, and when rubbed, a degree of 
superficial inflammation may succeed, sufficient to con- 
vert the lymph into an imperfect pus. The scabs of 
varicella are very small, and as the lymph wants a 
mucilaginous quality, they are granular. The desicca- 
tion is very rapid, and in sl\ days the complaint com- 
pletes the whole circle of its phases. 

I once saw varicelloid vesicles occupying the throat. 
The case was more severe than the common type of 
varicella, and was accompanied by a light febricula. 
Generally speaking, no constitutional symptoms of any 
importance are present. The tongue is clean, and the 
pulse unaffected. The aspect of countenance betrays 
neither languor nor feverishness. The appetite is good, 
and the sleep undisturbed. The complaint often shows 
itself in schools, and mns through all the young mem- 
bers of a family. It is manifestly both contagious and 
epidemic. 

Now, can tliis be a form of variola ? Observe the 
marked difibrences between the two disorders. Vari- 
cella has not the incubative period of variola. It has 
not the character of variolous eruption. Children take 
it almost exclusively, I do not say that adults never 
take it. 1 have seen a few adult females attacked by it, 
but it is a rare occurrence. This is not like variola. 
But far and above all, it is taken indiscriminately by

those who have and those who have not been vacci- 
nated. Its course is not in the sHghtest degree ahered 
by previously undergoing vaccination. It is now nearly 
always taken after vaccination. Whether it was taken 
equally after inoculation of small pox I cannot tell you 
from my own experience, but I have the authority of 
Sir Henry Halford for saying that it was ; and there 
are few physicians now besides himself who can be 
appealed to on such a point These general conside- 
rations are of themselves sufficient to decide the ques- 
tion of non-identity. 

But if we examine the subject still more closely, we 
find that the organization of the varicelloid vesicle dif- 
fers from that of the variolous. I acknowledge to have 
seen vesicles on the face, of a true varicelloid origin, 
which in aspect and arrangement closely resembled 
those of genuine small pox, but in the greater number 
of cases, especially when the vesicles of the trunk and 
extremities are examined, there is no uml)ilication, no 
central depression, no division into cells, no slough. 
There are simply partial elevations of cuticle, of irregu- 
lar and undetermined arrangement. Here we see no 
groupings into threes and fives, no crescentic or circular 
figures formed. Everything in varicella is hurried for- 
ward—the incubation, the eruption, the desiccation. 

These things seem so clear, that you may naturally 
be tempted to ask — how did the notion of identity ever 
originate \ A reply to this question will lead us still 
further into the consideration of diagnosis and general 
pathology. There is a disease which resembles vari- 
cella in its mildness, which really does arise from the 
variolous poison ; and physicians, in former times, look- 
ing only to the general, and neglecting the minute

anatomical characters of the erupdou, have thought 
proper to confouod the two diseases. By way of dis- 
tinction, we will call the one varicella vera ; the other, 
variola varicelloides. I do not say that mistakes can 
always be avoided. During the year 1842, a child 
was admitted into the Small Pox Hospital, baviug 
the incubative symptoms of variola, and the local 
symptoms of varicella. 1 remain doubtful about this 
case. Nothing but iuoculation with small pox could 
clear up the difficulty. In most cases, however, the 
diagnosis is clear enough. Let me enumerate the chief 
features of each complaint. 

la the true lymphatic varicella, there is no premoni- 
tory fever. In the variola varicelloides, there are at 
least forty-eight hours of preceding febrile disturbance. 
In the varicella vera, there are no hard van or tuber- 
cles. In the varicelloid form of variola, tuberculous 
elevations of the skin are distinctly perceptible. In the 
vesicles of the one, there are no central depressions ; iii 
the other, central depressions can always be traced, 
either by the naked eye or by the microscope. In the 
true varicella, the crusts are granular, and quickly fall 
ofl! In the variola varicelloides, the lymph being muci- 
laginous, the crusts arc firm, adherent, and drop off, en 
vimsc, at the end of six or eight days. Authors have 
described pits as having succeeded true varicellons 
eruption, but the occurrence is very rare. I have 
never seen any case where the inflammation ran so 
high as to admit of such a result. 

Hitherto I have not touched upon a question which 
you might naturally suppose would at once settle the 
dispute — I mean, the question of inoculation. Can 
varicella be communicated in ibis manner t The 



300 INOCULATION OF VARICELLA. 

question is more easily put than answered. Dr. He- 
berden blinks it He does not say he ever saw inocu- 
lation performed with the lymph of varicella, or rather 
serum (for it is nothing else), but he says that mistakes 
have been made in such inoculations, implying that the 
disease is propagable in tliat mode. 

Dr. Willau entertained the belief that varicella was 
so communicable ; but his experiments are few, and, to 
my mind, very unsatisfactory. I need not state them 
to you, because, since his time, Mr Bryce, of Edin- 
burgh, by more extended and careful observations, has 
set the question at rest He states* that he has inocu- 
lated with the fluid of varicella vera, at all periods of 
the disease, and at all seasons of the year, children who 
had never undergone either small pox or cow pox, and 
yet that he had never been successful in producing 
from it either variola or varicella. Since the date of 
IJrycc's experiments (1816) I know of none on the 
inoculation of varicella. 

[In the epidemic of varicelhi at the Hospital Nocker in 1 843-44, 
already referred to, M. Delpecli was unable to propagate the disease bj 
inoculation.] 

What, then, are the arguments which can be brought 
forward in support of the doctrine of identity ? There 
must be some, seeing that up to the date 1767, certainly 
for lUOO years since the disorder was known, physicians 
adopted that notion, which has even been revived in our 
own times. 

Dr. Thomson's great argiinients are these : — 1. Vari- 
cella prevails when variola prevails, and never without. 
Hence, says he, we may deduce the probability that

NOK-IDENTITY OF VARICELLA AND VARIOLA. 301 

one contagion is operating, not two. The answer to 
tliis argument is, that the facts are incorrectly stated. 
Varicella frequently prevails without variola. Dr. 
Mdbl has shown this most satisfactorily from the expe- 
rience of the Copenhageu epidemics. From i809 to 
1823, chicken pox was annually observed at Copenha- 
gen witliout accompanying variola. Since 1823, both 
diseases have prevailed epidemically, but the physicians 
could always trace their sources, and this convinced 
them that the generating miasms were distinct. 

Besides, the doctrine goes for nothing, if it can be 
shown, as has been shown over and over again, that 
some children take varicella after cow pock, and olhers 
cow pock after varicella, while some have cow pock 
and varicella going through their phases at the same 
time. I have published the details of a case of this 
kind which occurred to me in 1837.* 

Dr. Thomson's next argument is, that be had never 
witnessed chicken pox in those who had undergone 
small pox. I cannot imdertake to meet this objection, 
because I see so few children who have undergone 
variola ; and chicken pox is a disease of infantile life. 
I strongly suspect, however, that here also the facts are 
imperfectly known. All I can assure you is, that at 
the Small Pox Hospital no difficulties in diagnosis are 
acknowledged, save in a few rare cases. 

It cannot be doubted for one moment, after reading 
the details of this conlroversy in the works of Dr. 
Thomson and elsewhere, that a very large proportion 
of the cases of alleged secondary or recurrent small pox 
are really cases of genuine lympiiatic varicella mistaken

for small pox. Several of even the most recent writers 
on cutaneous diseases adopt Dr. Thomson's views, and 
apply the term varicella to those milder forms of variola 
called the modified and mitigated small pox. These 
writers distinctly avow their belief that all forms of 
varicella without exception are of variolous origin, and 
each susceptible of propagation by inoculatioa With 
such views, it cannot be a matter of surprise to any one 
that the question of recurrent small pox should still be 
so keenly agitated. 

The treatment of varicella demands no comment A 
little manna and magnesia, with abstinence from animal 
food for a few days, comprise all that is essential. 

HERPES. 

This disorder may be thus defined: — 

" An exantheiiia originating from obscure internal 
causes, and not propagating itself by contagion ; cha- 
racterized by partial clusters of phlyctcnae or vesicles, 
which are surrounded by areola ; preceded and accom- 
panied by fever, passing througli a regular course of 
increase, maturation, and decline, and terminating within 
a fortnight by small scabs." 

Such a disorder was well known to the ancient Greek 
and Roman physicians. The term herpes is derived 
from the Greek g^^w, to creep. The phlyctenae which 
characterize it derive their name from the Greek 
(pXvxraiva, a bUstcr ; or (pXiw, to bubble up. The best 
modern authors on herpes are. Dr. Willan, Dr. Bate- 
man, and Dr. A. T. Thomson, whose essay you will 
find in the " Cyclopaedia of Practical Medicine." 

Nosologists have delighted to form species of herpes. 
Five or six have been so enumerated. I shall be com-

pelled lo instruct yoii in tlieir names, but you will bear 
in mind tliat there is nothing palbologically important 
in these subdivisions. They display merely the inge- 
nuity of the nosologist. The leading variety of herpes 
is that called zosler (from the Greek ^ue-rnp, a belt, or 
^wvjfjinj, to girdle). By the vulgar in this country the 
disease is familiarly called the shingles — a corruption 
from the Latin cingulujii, a girdle. These deuomiua- 
tions it receives from the peculiar seat of the herpetic 
disorder, the waist, or rather, a circular line around the 
belly, commencing at the navel. I know of no other 
disorder which specially affects this portion of the 
human body. All oiher cutaneous affections appear 
on the face, the arms, the lower extremities, ihe scalp, 
the back, the chest. Herpes zoster alone fixes on the 
belly. 

1. The eruption of herpes is preceded for several 
days, sometimes for a week, by symptoms of general 
constitutional disturbance, occasionally aggravated into 
fever. Languor, low spirits, a succession of bad nights, 
a failing appetite, and weakness of the limbs, betoken 
some lurking disorder. Rigors and flushes, with a 
white tongue, are sometimes superadded, but the febrile 
symptoms, so far as my observations extend, never 
attain any considerable height. 

At length the eruption shows itself, and very fre- 
quenUy the precise spot will be indicated by a previous 
sensation of heat and itching, sometimes amounting to 
actual pain. I have seen some cases with so little pre- 
ceding constitutional disturbance, that the patient has 
been startled by finding the abdomen occupied by 
eruption. Inflammation first shows itself by the side of 
the navel, followed by the rapid formation of vesicles in 



L 



304 CHARACTERS AND VARIETIES 

clusters. These spread round the belly, generally (but 
not invariably) from right to left ; and a vulgar preju- 
dice teaches, that if they extend entirely round the body, 
the patient dies. This may be said very safely, for such 
an event is scarcely ever witnessed. The eruption 
seldom extends more than half round the body. A 
perpendicular position of the clusters is very rare. 
Rayer tells us, he once saw this arrangement on the 
thigh, but on the trunk of the body it is unknown. 

Herpetic vesicles are about the size of a pea. The 
areola surrounding them, which forms very early, is 
often considerable. They attain their maximum ot 
development in three, or at furthest, in four days. The 
contained fluid is at first perfectly limpid, but before 
desiccation, becomes opaque or semipunilent Dark- 
colored scabs succeed, which harden and fall off in the 
course of a week or ten days, during which time the 
skin cicatrizes. A certain amount of feverishness 
accompanies the maturation of the herpetic vesicles. 
Some relief to tlie constitutional depression is afforded 
by the development of eruption. 

[Tho vesicles of herpes vary in size from that of the head of a large 
pin to that of a pea, and sometimes reach a size much larger, by the 
union of two or more at their edges. 

The eruption sometimes commences on one side or the other of the 
median line i)Osteriorly, and sometimes there and at the median hne ante- 
riorly at the same time, the groups of vesicles then extending gradually 
from each point of origin until they meet.] 

2. Having thus made you acquainted with the fea- 
tures of the chief form of herpes, I will briefly allude to 
the other varieties of this affection. Clusters of her- 
petic vesicles running the same course with that now 
described sometimes appear on the chest, and extend

across the slioulder, in the usual direction of a sword 
belt. They may also show themselves on the extremi- 
ties. The course of the disease in such situations is in 
every respect ihe same as that of the regular shingles. 
Dr. Willan has distinguished this form of herpes by the 
spec)6e term pk/i/ctanodes. 

3. In some cases die vesicles which appear on ihe 
arms, shoulders, neck, temples, and groin, assume an 
oval, or sometimes a decidedly circular shape. These 
are called herpetic ringworms. Sometimes there shall 
be one such, sometimes many. To this variety of 
herpes the term circinntys is applied. This form of 
herpes is seldom accompanied hy any cognisable con- 
stitutional disturbance. The vesicles are very small, 
and they include a portion of unaffected skiu. The 
complaint, if so it uiay be called, runs its course in 
eight or ten days, but successive crops of vesicular rings 
may procrastinate recovery. Though called a ringworm, 
you will remember that this affection is not contagious, 
like the true ringworm of the scalp (porrigo scutulata). 

4. The term herpes iris has been appropriated to 
those forms of herpetic vesicles which forui on the hack 
of the hand, and arc characterized by the phenomenon 
of concentric circles of vesicles of different colors, yel- 
low, brown, dark red, and light red, corresponding to 
tlie period of inflammation in each successive crop. 
Their form is generally oval. The iritic form of herpes 
may display itself on other parts, but always where the 
skin is near the bone. 

5. The fifth variety of herpes is the herpes labialis. 
Here the seat of eruption is the upper lip. It is a fre- 
quent attendant on common catarrh, but sometimes also 
appears as an idiopathic affection originating from cold

and fatigue, and is then preceded for a day or two, by 
languor, lassitude, nausea, perhaps vomiting, and head- 
ache. I have seen it extend round the whole mouth, 
accompanied by such tumefaction that speaking and 
swallowing were exceedingly painful. The variety of 
herpes termed praeputialis belongs to surgery. 

The sources of herpetic fever and eruption are now to 
be considered. This complaint invariably has its origin 
in irregularity of one or more of the non-naturals, which 
you will recollect to be, air, aliment, the secretions — 
sleep and watching, exercise, and mental anxiety. Any 
irregularities in these will, in certain constitutions, give 
rise to an attack of herpes. Let me give you a few 
illustrative examples. 

A gentleman, accustomed, in his native county 
(Yorkshire), to great regularity of life, came up to Lon- 
don to engage in parliamentary matters. He sat till 
late at iii{;ht in the heated gallery of the House of 
Coiiiinoiis. He had his meals most irregularly, some- 
times dining in the forenoon, sometimes not till nine 
o'clock at night. His sleep was broken, and his mind 
harassed. After about a fortnight of this system, lie 
became languid and oppressed. Herpes zoster, fully 
developed, came to his relief, and in little more than a 
week he was restored to his ordinary condition of health. 

A young lady (Mademoiselle Missonicr) came over 
from France to England some years ago. She had a 
very bad passage. The hatches were closed. The air 
in the cabin was stifling. Heat, anxiety, change of air, 
change of diet, change in her habits of Hfe, conspired 
to disarrange the young lady's whole system. Herpes 
labialis in great severity succeeded, on the disappear- 
ance of which her health speedily returned. 



CAUSES OF HERPES. 



'In January, 1824, Mr. Simpson, one of my earliest 
papils, passed tbrough a severe form of low fever. At 
the end of the tiiird week, herpes labialls appeared, and 
coniiniied so long, and proceeded to such an extent, 
that for many days he could not speak Dor protrude 
his tongue, and hardly could he swallow enough to 
support life. His aspect was hideous. The saliva was 
so offensive that it could not he swallowed for more 
than a fortnight. It yielded at Icugtii, and subsided 
much quicker than could have been expected — in about 
six days. No medicine appeared to exert the smallest 
influence over it. 

We ujay enumerate the following, as some of the 
most usual sources of herpetic affections : — 1. Confine- 
ment to a hot and crowded room (defect of air) ; 2. 
sudden changes in the mode of life (irregularities of 
aUinent) ; 3. in infantile life, dentition ; 4. at all ages, 
prior disease of a catarrhal, bilious, or typhoid kind. 

With reference to causes, I would add that in its 
most perfect development, herpes occurs chiefly among 
adults. Children often display clusters of herpetic 
vesicles on the hand, arm, or below the ear, but seldom 
in any notable intensity. Herpes occurs more fre- 
quently in warm than in cold seasons. It attacks 
chiefly those of fine and delicate organization of skirt 
It is therefore more common in women than men. A 
disposition to herpes is hereditary ia some families. In 
the London Medical Gazette (vol. ii. p. 632) will be 
found a brief notice by me of a family named Swin- 
burne. The grandfather, nncle, and nephew, had each 
experienced an attack of herpes zoster. The boy had 
it at the early age of nine. It was strongly marked, 
affectiag the thorax, and extending from left to right 



308 MILIARIA : 

The treatment of herpes is very simple. In children, 
during the process of dentition, an eruption of herpetic 
vesicles is critical and salutary. So is the herpes labialis 
vvhich succeeds catarrh. Hence we may estimate the 
value of blisters in several forms of infantile feverish- 
ness, of catarrhal and gastric fever. It is often impos- 
sible to repress herpes, and if it were possible, it would 
be highly injudicious. 

Herpes zoster is to be treated by gentle laxative 
draughts, containing senna, magnesia, and its sulphate. 
Whenever herpes or any other febrile eruption is 
attended with much itching of the surface, magnesia is 
a useful remedy, for this itching indicates acidity acting 
on the denuded coats of an irritable stomach. A mix- 
ture of magnesia, mucilage, and the liq. opii sedativi, 
allays the uneasy feeling. You may direct, at the same 
time, a camphorated Saturnine lotion, which cools the 
part. Cold cream is a convenient means of allaying 
irritation. The black wash may be employed to the 
herpetic vesicles so often observed in infantile life. 

MILIARIA. 

The history of medicine presents few chapters so 
discreditable to physicians as that which is devoted to 
miliaria. It would certainly be to our credit to pass it 
over sub silentio^ but it is right that you should know 
something about it, and about the controversies to which 
it has given rise. 

Some obscure allusions to miliary eruptions may be 
traced in the writings of Hippocrates, but the term does 
not occur there, nor, in fact, is it anywhere to be met 
with until the middle of the seventeenth century, the 
period which I have aheady mentioned to you as 



ITS EARLY HISTORY. 



309 



famous for the perfection to which medical art had 
brought the healing, or alexipharmic mode of treating 
fever. About that period, some German writers de- 
scribed certain epidemic fecers having miliary eruption 
for their distinguishing character. These epidemics 
happened in 164:8, at Lubec ; in 3652, at Leipsic. 
In 1710, Sir David Hamilton, physician to Queen 
Anne, published a regular treatise on miliary fever, the 
English translation of whicli extends to 256 pages, and 
makes a goodly octavo volume. Later in the eighteenth 
century, it attracted the attention of Dr. Fordyce, in 
London, and of physicians in various parts of the 
continent, among whom may be mentioned, Allioni, 
Fantoni, Walthier, and Gastellier. 8auvages, in his 
"Methodical Nosology" (1768), devotes eleven quarto 
pages 10 miliaria, and only eight to variola! In 1760, 
De Haen, then practising physic with great success at 
Vienna, attacked the miliary doctors, and being himself 
rather fond of controversy, continued his attacks upon 
them with increasing severity for many years. 

De Haen labors to prove, and certainly to my mind 
succeeded iu proving most satisfactorily, that there is no 
, form of fever which has miliary eruption for its specific 
or distinguishing feature. "Miliary eruptions," he says, 
" are, like petcchisp, accidental occurrences in the pro- 
gress of fevers, which may be encouraged by certain 
modes of treatment, and diminished or entirely pre- 
vented by others." He shows up the inaccurate obser- 
vations and the loose reasoning of physicians concerning 
miliaria during the preceding hundred years, without 
the smallest mercy. 

Notwithstanding these cutting criticisms of De Haen, 
authors continued to write about specific mihary fevers 



I 



310 PHENOMENA OF MILIARY ERUPTION. 

for many years afterwards. Pujol described with great 
minuteness an epidemic miliary fever which prevailed in 
Languedoc in 1782. Since the present century set in, 
however, miliary fever has been at a discount. I know 
of nothing written on it in this country, but Rayer has 
detailed the particulars of an epidemic miliary fever 
which pervaded the department of the Oise (Normandy 
and Picardy) in 1821. The disease is duly noticed in 
all our systematic works. You will see it ably described 
in Dr. Craigie's work "On the Practice of Physic," 
and in the " Cyclopaedia of Practical Medicine," by Dr. 
Tweedie. 

It is greatly to the honor of Sydenham, that he never 
fell into the fashionable theory of miliary fever. He 
was aware of the occasional appearance of miliary vesi- 
cles, and of their causes, and he alludes to them espe- 
cially in his sketch of the fevers of 1685 and following 
years ; but it requires a careful study of his works to 
detect even this incidental mention of them. 

I now proceed to describe briefly (for I need not do 
more) the phenomena of mihary eruption. 

The first appearance of miharia is preceded by fever, 
with redness and roughness of the skin, especially on 
parts covered by the bed-clothes — the chest, belly, and 
thighs. After a time, the skin thus affected exhibits 
innumerable minute confluent vesicles of the size of 
millet seeds (whence the name, iiiiliuni), of a pearly- 
white color. Now and then small blebs, of a size 
superior to the common miliary vesicles, are seen inter- 
mingled with them. The duration of the eruption is 
uncertain, being, in point of fact, determined by the 
treatment pursued. Authors generally allowed a week 
for the continuance of the eruption, and state that it

thea terminated by thin crusts, with general desquaina- 
tioD of the cuticle. 

The symptoms which by the authors of tlie seven- 
teenth century were considered as the initiatory signs of 
miliaria were, sighing, oppression of the pr^cordia, rest- 
lessness, jianting of the breath, jactitation, cramps, sub- 
suhus teiidinum, and a sense of fulness and faintness. 
"I knew," says Sir David Hamilton (describing the 
case of Mr. Bullock, August 8, 1700)— "I knew, by 
the oppression of the breathing, and the languor and 
faintness of the spirits, that this would end in a miliary 
fever." It is scarcely needful to apprise you, that these 
symptoms indicated congestion of blood about the lungs 
and great vessels. The miliary eruption is accompanied 
by a pulse always rapid, and generally small. Some- 
times, however, we read of a hard, irregular, and inter- 
mitting pulse, co-existing with a crop of miliary vesicles. 
The tongue is often clean and moist. Much thirst is 
usually present. 

Mihary eruptions (termed by the old authors suda- 
mina) are always associated with a moist state of the 
surface, and the odor of the sweat is singularly rank, 
offensive, aud acid. This is tlie clue to the theory of 
mihary eruption. It never appears under a cool treat- 
ment, or with a cool condition of surface ; but it may 
appear in any fever where the surface is either naturally 
very hot, with a strong and full action of the heart and 
arteries ; or where such a condition of surface is 
brought on artificially, either by sweating drinks, or by 
sdmulating medicines, or by superabundant bedclothes, 
or the excessive heat of the weather, or the great exer- 
tions of the patient To give you some examples : — 

1. Miliary eruptions have always been observed in 



312 



APPEARANCES OF MILIARY ERUPTION. 



the l^ing-in room. To this three things contribute: 
the exertions of the woman, the closeness of the cham- 
ber, and llie caudle whh which the officious nurse siip- 
phes tlie object of her care. Tlie febris pucrperarura 
miharls is described by Hoffman, and all the writers of 
that day (17(J0). It is still occasionally seen under the 
same circumstances. 

2. Miliary vesicles occur occasionally in the early 
stages of ail fevers whose natural tendency is to dcve- 
lope eruption. They are obsened, therefore, and have 
been already noticed, as accompaaying the outbreak of 
small pox, measles, and scarlatina, and that witliout the 
additional aid of beating or forcing medicines. 

3. Miliary vesicles appear in the progress of all 
fevers treated by sweating remedies. You will remem- 
ber that it was In 1640, when this method of managing 
fevers had attaiued its acme of absurdity, thai miliaria 
first attracted the special attention of physicians. The 
most complete and universal eruption of miliaria which 
I ever saw was in the case of a young man, aged 
eighteen, laboring under acute rheumatism. His first 
medical attendant had enveloped his body in folds of 
flannel from head to foot, giving him very much the 
appearance of a mummy. When I took charge of the 
patient and unrolled this living mummy, the most 
superb crop of miliary vesicles was displayed which I 
bad ever seen, or ever expect to see again. The effect 
of such local treatment, and of tlie guiacum, camphor, 
and Dover's powder, which formed so prominent a part 
in the old treatment of rheumaiic fever, is not only lo 
drive the blood to the surface, but to gorge the large 
vessels of the lungs. Hence the dyspnoea. Now, if 
the blood is detained in the lungs and the cutaneous

capillaries, it cannot be in tbe heart. The supply of 
blood to the heart, therefore, is iuiperfect, and hence 
the fainting which made Sir David Hamilton know 
that his patient was going to have miliary fever. Cool 
the skin, and the tendency to faiiitness goes ofF, because 
the blood is then driven towards the heart. Upon this 
principle you treat a young woman who has fainted at 
church, wlien the congregation and the gas-hgbts are 
aUke numerous. 

When miliary eruptions occurred in the progress of 
typhus fever, it was generally remarked tliat they ap- 
peared about the tenth day of the fever, and declined 
about the eighteenth. All authors agreed that no criti- 
cal days were perceptible. Sometimes fresh crops of 
vesicles would appear and protract recovery. 

Attempts have been made to propagate nnliaria by 
inoculation, but, as you might anticipate, without eflecL 

Miharia, then, is cbieily an artificial exanthema. I 
will not say but that fevers may exist which have 
a greater tendency than others to develope miliary 
vesicles, but the idea of a purely miliary fever is now 
abandoned. 

The cure of tbe complaint need not detain us long. 
Tbe cause is, superabundant warmth and too violent 
action of tbe heart and arteries. When, therefore, you 
chance to meet this disorder, banish from your thoughts 
whatever you may have read as to the danger of sup- 
pressed eruption, and have no scniples about repressing 
it Throw off superfluous bedclothes, admit cool air 
into the apartment, refresh the skin by tepid abhition, 
provide the patient with cool, subacid drink, exhibit a 
mild laxative, and withdraw all stimulants. You will 
not then long be troubled with miliary eruptions. 



314 PEMPHIGUS AND POMPHOLYX. 



PEMPHIGUS AND POMPHOLYX. 

These terms designate such forms of cutaneous dis- 
ease as are characterized by the appearance of large 
vesicles, blebs, or bullae. Three varieties of bullous 
disease have been described, viz. — the acute pemphi- 
gus, the chronic pemphigus, or pompholyx, and the 
infantile, or gangrenous pemphigus. None of these are 
common, but the most frequent is the chronic variety, 
which I may begin by noticing. 

1. Chronic pemphigus, called also pompholyx, exhibits 
a succession of blebs on different parts of the body, with 
very little surrounding inflammation. No fever is pre- 
sent, and in many cases the evidences of constitutional 
sympathy are few and obscure. It is chiefly met with 
in the aged, and in those whose constitutions have been 
brought below par by debilitating causes, such as low 
diet, fatigue, anxiety, intemperance, residence in damp 
situations, diseased liver, or some other form of visceral 
disorganization. It is always symptomatic of a weak- 
ened, and very often of a broken down constitution. I 
saw a remarkable instance of the complaint many years 
ago in a woman seventy years of ago. Her face, arms, 
thighs, and buttocks were occupied by numerous blebs, 
of the size of walnuts. Their usual aspect was trans- 
parent, but some were livid, and these, when broken, 
displayed a dark subjacent corion. She died in the 
course of a few months, deriving very little benefit from 
the plans of treatment which I had adopted. It 
appeared to me to be pathologically allied to erysipelas; 
to be, in fact, an erysipelas erraticum, solitary blebs 
taking the place of the usual diffused inflammation 
with phlycteUcE or blisters. 



PEMPHIGUS GANGRENOSUS. 



315 



The treatment of chrooic pompholyx is neither well 
established nor very satisfactory I have seen blood 
drawn from the arm without either benefit or aggrava- 
tion of the symptoms. A warm bath is a good pallia- 
tive. Dr. Batcman praises bark, cordials, and diuretics. 
Sarsaparilla would naturally suggest itself as an appro- 
priate alterative and tonic. 

2. Dr. Bateman did not acknowledge the existence 
of any form of fever sufficiently marked to merit the 
title of acute pemphigus, but the old authors describe a 

fehris bullosa, and a few modern pathologists have done 
the same thing. The acute pemphigus is described as 
throwing out its peculiar eruption after a varying num- 
ber of days of fever. The abdomen and lower extre- 
mities are the usual localities. The subjacent corion, 
when exposed, appears red and tender. The disorder 
raay last a week, or be protracted to a month. It is 
occasionally associated with gastro-enteric irritation and 
an aphthous state of the mouth. It is scarcely con- 
sistent with sound pathology to view this otherwise 
than as an accidental complication of bultse with dysen- 
tery or typhus. As such it ought to be treated, 

3. The pemphigus gangrenosus of infajits has been 
ably described by Dr. Whitley Stokes in the Dublin 
Medical and Physical Essays. It is chiefly met with 
in children under five years of age. It commences 
withont fever. Numerous blebs and vesicles appear on 
the skin, succeeded by sores, discharging a thin ichor. 
Sloughy ulceration destroys the skin and neighboring 
textures, and speedily exhausts the already weakened 
child. The chief seals of the blebs and sores are the 
ears, mouth and lips, hands and feet, the genitals, breast, 
and belly. The disorder prevails more in winter than 



I

in summer, and affects those especially who reside in 

datup localities. 

It is obviously a disease of the same nature as the 

cancrum oris that succeeds measles. It is brieSy 
I alluded to by Dr. Bateman under the title of Rupia 
' esckarotiea. Its treatment must be conducted on the 

principles applicable to gangrenous affections occurring 

in exhausted habits. 

Tills disorder is known in Ireland by the name of the 

Hives, and it would appear from the population returns 

that a large number of children in that country die 

annually from such a disease.

Conclusion. 

We come now to llie consideration of tliose forms of 
febrile eruption wliicli are not associated witli actual 
inflammation of the corion, and conseqaently exhibit 
no traces of fluid efi'usion. We call them the siniple 
efflorescences, and they have for their coniniou patholo- 
gical feature a more than average supply of blood to 
the cutaneous vessels. They are four in number : — 
lichen, urticaria, roseola, erythema. 



The term \i,^-^<, was introduced into medical litera- 
ture by Hippocrates, who applied it to designate a 
species of chronic tetter, the precise nature of which is 
unknown. Since the adoption of Dr. Willau's system 
of cutaneous nosologj-, lichen is appropriated to an 
eruption (sometimes attended, sometimes unattended, 
by fever) consisting of small elevated papulse, which do 
not run into vesicle or pustule, but terminate by scurfy 
desquamation. Such a disorder acknowledges various

causes, and occars under veiy opposite conditions of 
the body. It is not contagions, is dependent on no 
miasm, and may recur frequently to the same indi- 
viduaL 

Such is the definidon of lichenons eruption. Dr. 
Willan has introduced into his work a great variety of 
species of the genus Bchen — viz. the lichen simplex^ 
agrius^ circumscriptus^ pilaris, lividus^ urticatus, and tip- 
|MC08. Every trifling alteration in the appearance of 
the eruption has been magnified into importance, and 
beat made the foundation of a species. I cannot see 
the utility of these learned minutie. When the difier- 
ences are such as indicate important distinctions in 
pathology, or affect materially the treatment, they may, 
and indeed ought to be adopted, but not otherwise. 

]. The first kind of lichen that I shall describe to yon 
b the lichen febrilis of adults. 

This complaiut is cue of the most frequent sources of 
difficuhv and error iu exanthematic diagnosis. A modi- 
fication of febrile lichen, perhaps the disorder itself, is 
called bv some ** rubeola sine catarrho.*' Lichen is fre- 
queutiv mistaken for true measles, and almost as often 
lor small pox. Not a vear passes over without our 
Kc^iviu^ at the Small Pox Hospital, three or four 
patieuts having this form of febrile eruption ; and, to 
cwiliess the truth. I have myself, in former times, mis- 
taken the compfaunt for small pox 

Lichen tietwihs affects chiefly adults. Its familiar 
diw^natMa u^ a smfi^. Its most usual cause is, sudden 
«ipwtti^ lo coM when the body is perspiring proftisely. 
Hmc^^ bv 6ur the most frequent subjects of it are cooks, 
wW in their nsaal callings, are suddenly taken Irom 
l^faf 1^ hi|p Christtnas fire to a cold scullery or a 



damp coal cellar. But lichetiouy eruptions display 
tlieuiselves wliere the same cause cannot he traced. 
We are justified, therefore, in concluding that other 
"vices of the non-naturals" (to use the language of our 
professional forefathers) may occasion iichenous fever 
— such as irregularities of exercise, sleep, and diet. 
Modern pathologists concur in attributing a large pro- 
porlion of such cases to disturbance iu the gastric and 
hepatic functions, and there can be no doubt but that 
the skin sympathizes largely iu the morbid affections 
of the liver aud stomach. The old authors were fully 
alive to the importance of this doctrine, and mentioned 
the vitiu secretorum et excretorum as leading to lichen. 
An eruption, truly Iichenous in its character, is frequently 
associated with typhoid fever. It is perhaps the most 
constant of all the evidences of secondary syphilis. 

Febrile lichen has an incubative stage of twenty-four 
hours only. This is the great secret by which to effect 
the diagnosis of lichen from the greater exanthemata 
(small pox and measles). There is here the same lan- 
guor and lassitude, the same sickness, restlessness, debi- 
lity, and loss of ajipetite, the same confusion of intellect, 
and general diminution of secretion, which characterize 
eruptive fever under other circumstances, Lichenoua 
eruption usually appears over the whole surface of the 
body at once. I have seen it in the course of twelve 
hours as vivid on the lower as on the upper extremities. 
This happened to me, to witness, on one occasion, in 
consultation with Mr. Money on the case of a young 
woman who had travelled up by railway from Birming- 
ham. The confusion prior to her journey, and the heat 
during and succeeding it, had, in common parlance, 
healed her blood. The result was, a sudden and severe 



320 DIAGNOSIS OF LICHENOUS ERUPTION. 

burst of febrile lichen. A few days of rest restored the 
system to its normal condition, but in the meantime 
great alarm had been taken in the fashionable hotel at 
the west end of the town in which she was lodged, 
under the persuasion that confluent small pox had 
broken out there. 

The eruption of febrile lichen is sometimes nearly as 
vivid as that of scarlatina, but generally it is of the 
darker or venous color, characteristic of rubeola. Some- 
times its color is so deep as to induce nosologists to 
dignify the occurrence by the name of lichen lividus. 
The eruption of lichen is decidedly j^apuli/orm. Ele- 
vations of the skin in the form of pimples, close set, or 
confluent, and very extensively difiused, can be per- 
ceived. The eruption is accompanied by considerable 
itching. Its usual course is as follows. On the second, 
or at furthest, the third day, it fades. The associated 
fever diuiiuishes. The patient expresses a desire to get 
up, and in less than a week is again at her ordinary 
employments ; I say, her employments, because the 
disorder is so much more common in females than in 
males. 

The diagnosis is to be effected — 1. by inquiry into 
the prior history of the patient ; 2. by the shortness of 
the incubation ; 3. by the character of the eruption ; 4. 
by a comparison of the quantity of eruption with the 
intensity of the accompanying fever. The eruption, 
from its amount, would perhaps suggest the idea of 
small pox, but the fever necessary to develope so much 
variolous eruption would not correspond with that 
which would be present in a case of Hchenous eruption, 
however full and confluent 

Lichen febrilis is a disease of no danger. It arises 



LICHEN FEBRILIS OF CHILDREN. 3S1 

from causes not affecting any of the great organs essen- 
tial to life. It therefore never appears in the tallies of 
mortality. A few doses of opening medicine, low diet, 
and some saline draughts, include all that 13 essential 
with regard to treatment. 

2. Lichen febrills of children. During the process of 
teething, and again when under process of vaccination, 
still more frequently when these two processes are 
going on simultaneously, children are very liable to be 
attacked with lichen. The complaint, as it occurs in 
infantile life, is called strophulus Iiy most authors, bat 
the character of the eruption is simply lichenous. some- 
times with, sometimes wirhout, sympaihetic fever. 
Strophulus — the red gum or infantile lichen — has been 
split and subdivided by the cutaneous nosotogists into a 
variety of species, the specific differences being some 
accidental and unimportant shade of color, or unusual 
mode of grouping of the papulie. It will be sufficient 
to have merely enumerated them. They are — stro- 
phulus interiinctus, albidus, confertus, volaticus, and 
candidus. Many cases of strophuhis are compatible 
with a good state of health, and really require no medi- 
cal treatnienl wliatever. 

When lichenous eruption arises in the infant from 
the vaccine poison, it usually shows itself on or after 
the eighth day. It is most common in the warm 
months of the year, and in children nourished on a 
good breast of milk, and full of blood. But peculiaritjr 
of habit will suffice to develope it in some children 
without such contingent circumstances. It frequently 
occasions great uneasiness to the parent, who is 
impressed with the belief that her infant has taken 
small j)ox, or been vaccinated from an unhealthy child 



322 cHEomc lichkii. 

or cot with a fool lancet None of these nodons are 
ibaoded in reason. Vaccine lichen may continne to 
show itself for ten dajs. It then gradaallj sohsides, 
especially with the aid of a little aperient medicine. A 
powder cootaioiog ooe grain of calomel with five of 
jalap and five of rhabarb, may be divided into foor 
parts, of which ooe should be taken daily. 

3. Licheo cfaronicns syphiliticus. The third variety 
of lichen is that which attacks adults in a chronic form, 
as the secondary offspring of the venereal poison. To 
describe the appearances of venereal lichen is the doty 
of the lecturer on surgery. I have no wish to poach 
upon his manor, but as the diagnosis of exanthematic 
affections may be materially aided by your knowledge 
of lichen syphiliticus, I may tell you briefly the princi- 
pal points in its history. This variety of lichen has its 
chief seat between the shoulders, and it sometimes 
extends over (he whole back. It is often accompanied 
by, or alternates with, syphilitic iritis, or syphilitic 
affection of the throat. It is rarely, if ever, associated 
with fever. It is very chronic in its nature, often per- 
sisting for three weeks or a month. I have known it 
to continue for upwards of a month, especially where 
no remedial measures are adopted for aiding the elimi- 
nation of the poison. This kind of lichen is much 
benefited by gentle doses of blue pill, and decoction of 
sarsaparilla with hydriodatc of potassa. 

['1'Ih- j'jij'ular form of sy|'liilitic cnijili.jn is also vt/ry fn'qucnth' seen 
on the linihs, of which it iin)st commonly occiijties the external surfaces, 
«nd is very rarily found on tlie cliest or <ni the abdomen.] 

These are the three varieties of lichenous eruption 
chiefly observed in this country. It remains that I 
notice one other, exceedingly common in hot climates. 



where it is known hy the name of the pr'tchly lient. 
From nosologists it has received the appropriate name 
of lichen tropicus. 

All Europeans, on (heir first arrival in a tropical 
climate, suifer more or less from this affection. It is 
the direct effect of the burning rajs of a vertical sun 
upon the tender and irritable white skin, unprotected 
by a rete mucosum and its black pigment. Many con- 
tinue to suffer iVom it in spite of acclimatization. We 
can sometimes trace, even in this climate, during the 
months of July and August, an approach to the lichen 
tropicus. The character of the eruption is purely 
lichenous — that is, papulae elevated, hut not advancing 
to fluid effusion. The great peculiarity of lichen tropi- 
cus is the intolerable pruritus or itching wliich accom- 
panies it. All that we see of the itchiness of lichen in 
this country gives hut a faint picture of the miseries 
endured by the unhappy European suffering under 
lichen tropicus in the East Indies, especially when the 
cutaneous circulation is e.vcited by such exercise as 
brings out perspiration, by drinking wine, or even 
laking hot soup at dinner. The sensation is a horrid 
compound of heal, tingling, itching, and pricking. The 
cold bath rather aggravates than appeases the sufferings 
of the patient, especially during the glow that succeeds 
the immersion. 

We have the liigh authority of Dr. James Johnson 
for saying, that until the constitution liecomes assimi- 
lated to the climate, the only thing that can he done is, 
to use light ciothhig ; to he temperate both in eating 
and drinking ; to avoid all exercise in the heat of the 
day ; to keep the bowels gently open ; and to resist, 
with stoical flrmness, the disposition to scratch.

CECes»iTe bent of our xnmrner months, nnd >a quiu mild, being attended 
with but very Utile itching, and rarely leading those who have it to

URTICARIA. 

The febrile nrticaria, nr nettlerasb, is an exanthema 
usually of a very niilii or benignant kind, possessing the 
following characlers ; — 

It displays elevations of the onter surface of the 
corion, of considerable extent, and usually of a circular 
fonn, of a wbite color, to which the term wheals b 
popularly applied. These eminences, or wheals, are 
aometimes persistent, but more commonly they fade 
during ihe day and return with the return of night. 
They are always attended with troublesome itching, 
and the alfecied parrs are hot. The accompanying 
fever is sometimes severe. Sometimes little or no con- 
stitutional affectiun is perceptible. It occurs to persons 
of all ages, and acknowledges several sources, but has 
DO origin from miasm. 

Urticaria, like lichen, has been a favorite complaint 
with uosologisis. Every minute deviation from the 
ordinary character of the eruption has been tbe signal 
for the creation of a fresh species. I know but of two 
Kinds of urticaria, the acute and the chronic; but Dr. 
Willan gives iis no less than six. The chief source of 
the disease is to be found in some peculiar irritabiliiy 
of the skin. Those who once suffer from it are liable 
to it again and again. In such a condition of tbe sur- 
fece, tnaiiy causes suffice to bring on an attack. 

1. The simplest form of uriicaria is that which arises 
from tbe local application of nettles. Uence tbe name 




-'' CRTICARIA FEBRILla. 325 

— urlica, a nettle. Some animals of the uiolluscous 
kind have a like effect apon the skin. 

2. The acute or febrile urticaria is a wpII marked 
variety of exanthema, of which, in the course of my 
life, I have seen several striking examples. The incuba- 
tive stage is short, and presents no pecuhar characters. 
This eruptive ailment is attended with const iiutional 
excitement, or fever, much more intense than the 
nature of the exanthem would lead you to expect 
The heat o( skin is often as great as in scarlatina. 
The pulse is active. Delirium and other evidences of 
constitutional disturbance are souietimcs met with. 
Dr. Elliotson first taught me tlie necessity of taking 
blood from the arm in severe cases of febrile urticaria. 
The blood will be found highly cupped and budy, 
evidencing the inflammatory nature of the disorder. I 
have followed the practice with great advantage, and 
strongly counsel you to pursue the same line of treat- 
ment. On several occasions I have tried to do without 
it, and have failed. The itching and heat accompany- 
ing febrile urticaria are great sources of discomfort 
They admit of partial relief from the use of the decoc- 
tion of bran, with a little spirit of rosemary. Purgalive 
medicines are useful, but it is better to draw blood 
moderately from the arm, than to attempt to subdue 
any considerable amount of iaflammatory fever by pur- 
gatives alone. 

I know nothing of the immediate causes of the febrile 
urticaria different from what I stated with reference to 
the acute forms of herpes and hchen. Any notable 
deviation from (he ordinary course of life may end in 
an attack of acute urticaria. Severe exercise, exposure 
to cold, a draught of cold water taken when tlie body

i%overbeate4 may prove an exciting cause* AH thff 
more urgent cases of orticaria, therefore, occur in per^ 
sbns between the ages of fifteen and twenty-five, but 
other periods of life are not exempt firom the malady* . 
The vaccine poison, when developed in great aboiH' 
dance in a plethoric child, has brought out urticaria^ 
with some fever. Certain articles of food will produce^ 
in particular habits, where the skin is irritable^ an 
ephemeral feverishness, daring which an * urticarial 
exanthem shall display itself. Almonds, or pnisrie 
^ciA in any ^ape, has this effect on some ; lobsten^ 
shrimps^ and certain other kinds of shell-fish, on othenn 
Cucumbers, vinegar, cayenne pepper, honey, mush- 
rooms, and other vegetable substances not possessing 
apy particular noxious principle, will have a like effect 
on a third class of persons. 

This latter kind of urticaria is very evanescent A 
gentle emetic, followed by a mild laxative, su£Bces for 
its cure. 

3. A chronic form of urticaria has been observed, in 
which the eruption appears and recedes alternately for 
a great length of time, without fever or any perceptible 
derangement of the general health. It probably arises 
from some irregularity of diet, such as over-indulgence 
in wine, or food of too stimulating a quality. According 
to the permanence, extent, or firmness of the wheals, 
tlie disorder is denominated urticaria evanida, perstans, 
conferta, snbcutanea, or tuberosa. 

In all these chronic forms of urticaria, warm baths, 
restrictions on diet, with the use of magnesia, or other 
simple laxative, are generally found adequate to effect 
a cure. 



VARIETIES Oi' ROSEOLOUS RASH. 






ROSEOLA. 

The term roseola is appropriated to a mild rash of. 
a rose color, appearing in patches of Irregular shRpe,> 
without any pimples or perce[itible elevation of the 
corioD. This disorder is accompanied by a light 
evanesceot febricula, and is not contagious. 

Little need be said concerning a disorder which,! 
except as it may lead to mistakes in diagnosis, wouldt 
hardly be reckoned worthy of notice. On that ac-* 
count, however, the circumstances under which ij' 
appears deserve some attention. 

1. A roseolous eruption occurs in the hot months of 
le year, and occupies (as roseola generally does) ihrf 

;e and upper parts of the body. It is called ihft 
iseola sestiva, and if accompanied by any affection of 
,e throat is probably a mild variety of scarlatina. 

2. I have occasionally seen roseola in females of ple-f 
thoric habit and irritable temperament. In them, a 
little extra exercise, an additional glass of wine, nay, 
sometimes emotion of mind, will throw out a roseoloutf 
rash over the neck and bosom. Such women may bel 
said to blush, not only with the checks, but with th« 
whole upper part of the body. 

4. A roseolous rash occurs often in children in coa<-' 
nexion willi dentition (roseola lufantilis). 

5. The most Important of all the varieties of roseolft- 
is the roseola exanthemalica, or variolosa. It happetu 
occasionally that after one, two, or three days of fever, 
a roseolous rash is suddenly tbrown out over the face, 
neck, arms, and back, in irregular patches. In some 
cases, this eruption assumes the aspect of scarlatina. 
On the second or third day from the appearance of this 




LUIS ^^_ 



328 ROSBOLA bxanthbmatica; 

rose-colored or scarlet rash, pimples display themselves 
in the very midst of these patches. These gradually 
advance, and in three days more show the depressed 
centres of variola. The occurrence is very annoying 
in practice. The physician first pronounces that his 
patient has fever. Two days afterwards he changes 
his note, and informs the friends that the patient, 
besides fever, has the roseola, or rose-rash, an affair of 
no cousequence. Two days after that, he announces to 
the astonished listeners that the patient has small pox ! 
This once occurred to myself in consuhation with Mr. 
Hammond, at Windsor. Three diseases in as many 
days ! The unprofessional man considers this impos- 
sible, and is perhaps disposed to question the sagacity 
of his medical attendant, but in this he is wrong. He 
is deceived, because he has neither studied the pheno- 
mena of exanthematic nisus, nor reflected on the 
manner in which exanthematic maladies slide into each 
other. 

Roseola exanthematica frequently accompanies the 
incubative stage of post-vaccine small pox. It indicates 
invariably the advent of a mild form of variola. It was 
a frequent attendant on the inoculated sn)all pox, and 
always hailed as a good omen by the professed inocu- 
lators. The most perfect specimens of roseola which 
can now be seen are those which attend the develop- 
ment of cow pox in some children of irritable habit and 
delicate skin. 

The treatment of roseola offers no topic of sufficient 
importance to arrest our attention. I have seen one 
case where the urgency of febrile tumult demanded the 
abstraction of ten ounces of blood from the arm. 



VARIETIES OF ERYTHEMA. 



' The last in the series of eruptive fevers is erythema, 
which is so closely allied to roseola that it is only a 
stretch of nosological refinement whicli lias separated 
tbeni into distinct disorders. The term EpuS^^in, as used 
everywhere by Hippocrates, simply denotes redness; 
and it is tlierefore correctly applied to any disorder 
having for its character simple efflorescence, not accom- 
panied by swelling, and not advancing, under common 
circumstances, to vesication, Bat this is the nosological 
definition of roseola. Having so many terms, there- 
fore, to express the same thing, we cannot wonder that 
modern aulhors should have differed in their acceptation 
of the term erythema. Some hold it to be merely the 
mildest form and earliest stage of erysipelas ; others 
restrict the term to such cases as exhibit redness of the 
skin, in patches, with some concomitant consliditional 
disorder, but neither originating in a contagious miasm, 
nor terminating in flnid effusion. In this sense I shall 
employ the term, but I shall not detain you long either 
with the history or the pathology of the disease. Ery- 
thematous eruption, indeed, offers little to interest 09, 
though, as usual, nosologists have done their best to 
turn lliat little to good account. Dr. Willau describes 
six species, varieties, or rather, as we ought to say, 
shades of erythema, to which he gives the names of 
erythema fugax, iteve, marginatum, papulatnm, tuiiercu- 
latum, and nodosum. Without attempting any formal 
description of these several kinds of efflorescence, I may 
state briefly all that it concerns you to know concerning 
erythema, its aspects, sources, and most characteristic 
variety. 



330 VARIETIES OP ERVTHEHA. 

Erythematous redness is sometimes obviously depend- 
ent upon the presence of local irritation, such as pres- 
snre, friction, distension, cold, heat, the bites of insects, 
acrid and stimulating applications, wounds, and ulcers. 
At other rimes, it originates idiopathically without any 
obvious cause, and is then attributable to some deraoge- 
mem of the hepatic, gastric, or nervous systems. 

Tlie best illustration i can give you of local erythe- 
matous redness is tiie areola of cow pox. It does not 
commonly advance to vesicle. We are therefore hardly 
justified in calling it erysipelatous redness. Yet to 
show yon bow nearly allied are the two disorders 
(erytiieiiia and erysipelas), I may state, that occasion- 
ally the vaccine areola does merge in erysipelas, and by 
so doing creates no small alarm in the mind of the 
patient or parent It is not uncommon to see the 
re-vaccination of adults followed by irregular erysipela- 
tous areola. 

Patches of erythematous redness appear at uncertain 
times in the progress of various kinds of febrile disease, 
especially of the low and typhoid character, and in 
many chronic affections, especially those of gastric or 
hepatic origin. Erythema is an almost constant atten- 
dant on ihc aggravated cases of anasarca, where [be 
skin is put upon the stretch. Under such circumstancea^ 
it appears in streaks of a dark red or purple hue. The 
intertrigo or dialing to which both infants and aged 
persons are liable, especially when very fat. Is of the 
nature of erythema. Sinapisms, pitch plasters, turpett* 
tine, and ainmoniacal embrocations, arc applied for th^'^ 
express purpose of exciting erythemalous rednesis

ERYTHEMA KODOSirM. 331 

these varieties of erylhema are obvioaslj' sjmptomalic. 
The only importaot qiiesrion for onr consideration is, 
wlietber there exists any disease liaving erythematous 
redness lor its chief character, siilhciently distinguished 
from erysipelas and from roseola to be entitled to sepa- 
rate examination T There is such a disease, and it is 
called erythema nodosum. It is a mild exanihem, being 
often preceded and accompanied by fever. It is distin- 
guished from erysipelas, in tliat it does not nm into 
vesications. It is distinguished from roseola by the 
circumstance of its occupying tlie lower parts of the 
body, to the exclusion of the upper. 

Erythema nodosum is characterized by patches of 
efflorescence occupying the skin lynig over the tibia. 
The patches are oval in shape, the long diameter being 
parallel to the tibia. They slowly rise into hard and 
painful protuberances, and present very much of the 
appearance of nodes. I have seen this disorder ushered 
in by a kind of irregular or low fever, with foul tongue, 
impaired appetite, and a faulty state of the secretions. 
Languor and lassitude have been the predominant 
symptoms, and the patient has often been surprised by 
accidentally discovering the eruption. This complaint 
is chiefly met with in young women between the ages 
of fifteen and twenty-five. I once saw it in a delicate 
lad, the apprentice of Mr, Courtney, formerly chemist 
and druggist in the Regent-circus. 

Erythema nodosum is a tedious disorder, often 
extending to three or four weeks, during the whole of 
frilicbifHliod-'' ' only urgent symptoms are languor

are reqnired ia the first instaace. The acidulated 
decoction of hark may afterwards promote the return of 
■trength. 

The same observalioas which I have made with 
reference to the origin of herpes zoster, urticaria fehrilis,' 
and lichen febrihs, apply equally to erytliema Dodosum. 
These febrile efflorescences are all closely associated in 
their pathological features ; they constitate the extreme 
links of that chain which connects the specific exanthe- 
mata with the febrile diseases of the human body, where 
the skin is simply dry. In those fevers yon find increased 
action of the cutaneous vessels, but it is neither of that 
kind, nor is it in (hat intensity which ends in eruption. 

Everything tends to show that there exists in nature 
a great law binding together fever, simple efflorescence, 
and specific exanthem, Thronghont the preceding 
lectures, this principle has been frequently illustrated, 
and as it is one of the most interesting which dermatic 
patliology presents, so is it that which warns uie that 
' here my labors terminate.

published in 1849 ; while, in a general summary of the causes of death, in a sub- 
sequent part of the same work, the word " sore throat" is not used, and the whole 
number entered there under the head of scarlet fever corresponds exactly with 
those in the ubles under the two separate heads of scarlet fever and sore throat. 
In the same ubles, there is a separate head for " quinsy/' and another for " mem- 
branous sore throat ;" hence, we felt authorized in considering those entered under 
the head of " sore throat" in the tables as cases of scarlet fever. 



844 AFFEirDDC. 



[ C— Page 18. ] 

The co-existence of two febrile exanthemata in the same individual has 
now been observed in so many instances, and so many cases of it are ob 
record, that its occurrence may be considered as beyond donbt We have 
added a few to those mentioned by our author, to show still farther ob 
what authority this settlement of the question rests, and to illustrate the 
laws by which it is governed. 

Dr. P. Tracy (of Norwich, Conn.) reports {Medical Repository, vol. iii. p. 
105) a case in which measles and small pox occurred at the same time in 
the same individual, and each pursued its regular course without mterfering 
with the progress of the other. 

In another case, he inoculated with a variolous matter a young man whd 
had been exposed to measles a day or two previously. The variolous 
disease was mild, and progressed regulariy, and on the tenth day the pre- 
monitory symptoms of measles appeared, followed the next day by the 
characteristic eruption, which parsed through its stages regularly to a 
favorable termination. Neither of these patients had been previously 
affected with measles, but communicated that disease to a considerable 
number of patients in the hospital, who had not been otherwise exposed. 

A case is also stated by Mr. Delagarde, in the 13th vol. of the Medico- 
Chir, Transactionsj of the co-existence of measles and small pox, in which 
the characteristic eruption of each appeared at the same time, and ran 
through its course ref^ularly. A child inoculated with matter taken from 
one of the pustules had tlie small pox. 

Dr. VVitIierin<r, in his work on scarlet fever (p. 25), alludes to two chil- 
dren (the only two instances he ever saw) who had scarlet fever and suiall 
pox at the same time. 

Dr. John Watson reports a case {Vmted States Medical and Surgical 
Journal, Oct. 1835, p. 8i)) of tlie co-existence of measles and scarlet fever 
in a boy eijrht or nine years old, examined hy himself and another physician, 
and decided to be measles, in whom there appeared, two days after, the 
characteristic eruption of scarlatina, with swollen throat, and red tongrue, so 
far as it could be examined, and which proved fatal soon afterwards. He 
subsecjuently attended two children in the same house with scarlet fever, 
who had desquamation of the cuticle, iind anasarca of the legs. 

Mr. (Jilder reports a cast' {Med. Chir. Transar., vol. xii. p. 106) of a 
child, fourteen months old, vaccinated during the premonitory sUitre of 
measles, in which each disease pnssed through its regular stages, without 
interference with the other. The progress of the disc-ase was also perfect 
in an infant vaccinated with matter taken from its arm. 

Mr. Little, in a letter to Mr. Dumiing, relates an instance of casual 
chicken pox passing through its regular stages, refrardless of the local 
action of cow pox, and also alludes to a case of casual measles which came 
under his observation, which progressed undisturbed by the cow pox. 



846 



{Comparalhv Stalemmt of FaeU ami OhMenationi relalive to tin Coa Pox. 
London, 1800, p. 28, note.) 

The two following cases are reportcHi by Robert Barnoa, M.B. ^London 
Lancet, May, 1845), ns inatiLnces of inrection of the ByBtem at Ihe iunie time 
by the poison of mmiW pox and of scarlatina. A girl, nine jreHre old, hud 
a/lnptoDts of malaise, &i.c., with a red tongue, fiiuces injected, niid a rash. 
Ill two days the rash di-tappenred, and papul» of varioloid appeared more 
diatinclly, and ran through their regular course, the patient having vaccine 
Bcnrs. At the end of three weeks, she liad anasarca. Twelve days after, 
three Bisters had varioloid, and another girl in the house had irarlalrna. 
One of the sisters oUo had sore throat. Hence the writer says, " It may be 
fairly presumed, that the first patient served as (he common focus of con- 
tagion from whence tiie two disenHes were propagated ; that she not only 
labored under the two diseoseti conjointly, but tmnsmitted them separately 
to other individaals." 

It is proper to odd, (hat these coses of Mr. Barnes are regarded by Mr. 
Uonon aa instauces of small pox preceded by variola. We have not 
nnfi^uenlly seen variola tliua preceded, and have not heailaled to regard 
as such eome cases which have been reported as those of the co-existence 
of rarioln and scarlatina ; bnt, in the present instance, feel that the occur- 
rence of anasarca at the end of three weeks, and the case of acarlatiiia in 
the same house, furnish strong presumptive evidence b favor of the view 
token by (he reporter of (hem. 

Mr. Marson, surgeon to the Small Pox and Vaccination Hospital, London, 
in a paper on the co-exislenee of different eruptive fevers, stales that he hoa 
*een seven coses of the oo-existence of variola and scarlatina at that instita- 
tioii during the l^t eleven years, and that three coses had occarred at the 
London Fever Hospital within Ihe lost few years. He also alludes to 
numerous other instance* of the co-existence of different eruptive fevers. 
(Limd. Mrd. Oas., June 18, 1847; also Paper on Co-exinleiice of Small 
Pox and Scarlatina, Jtteit. Chk. Tram., vol, ux. 1847.) 

MM. Barthei and Rillict hove seen scarblina co-existing with measles 
seven times, variolous eruption twelve tines, and erysipelas three times. 

M. Levy, in his memoir on measles in the adult, also gives instuncea of 
the co-exlt(ence of different febrile exiiiithemata. (_Mai. Chir. Rev^ Oct 
1847.) 

Dr, John Wal.ton also, in a paper read before Ihe New York Medical and • 
Surgical Society, in M.iy, 1835, has collected othtr cases of such co-cxiat- 
cnce, and also gives in detail some of those to which we have referred, 
(r. Slates Med. and Surg. Jour., Oct 1835.) 

The cases quolcd by our author (p. 135) fntm Dr. Russell at Aleppo, of 
the simultaneous occurrence of measles and small pox in (he same per- 
son, may be found in the Mai. Chir. Tram., vol, iL p, 90. Ojic was in «

both cases, each eruption pursued its regular course, and with a &vonible

Mr. E. O. Bpooner mentione a caae aa nnder bia care at the tSme of 
writing, of a woman, aevenfy yeara of agOi who, alzty yeaia previooalyt had 
been auceeaafally inoenlated tor email pox, and iHio boie ita peenUar Barim 
botii on her arm and on her body, and waa then reoovering from a eeeond 
attack of casual small pox. (Provinc. Med, and Sta^. Jour.^ July, 1850.) 

Dr. John Watson, of this city, has reported a well marked case of a 
eeeond attack of small pox in a child two years and ten months old. 
(^United Slates Med, and Surg. Jour., Oct 1835.) This child we ourselves 
aaw, and felt satisfied at the time, from the character of the eruption and 
from the marks left by a former attack, that it was undergoing the disease 
a second time. 

M. Gilet reports a case {VAhetOe Med., Paris, Oct. 1844, p. 239) of the 
confluent form in a woman eighty-seven years old, who had a scar of small 
pox on her forehead from the disease in infancy. 

Dr. Renaud gives a case (Revue Mtdicale, Feb. 1839) of a little girl, 
twenty-eight months old, who had small pox in the distinct form in August, 
1838, and died from an attack of it> in the confluent form, in October of the 
same year. The grandmother on the maternal side had been twice affected 
with small pox, and the mother, who was twenty-six years of age, and who 
nursed the child, and had the disease in her infancy, took it again a short 
time after, and died with it, in the confluent form, on the seventeenth day. 

The frequency of its recurrence, as well as its fatality when it does recur, 
varies with different epidemics. 

In France, in 1840, of 14,470 persons attacked with epidemic small pox, 
it occurred a second time in only twenty-four cases ; and of these, three 
proved fhtal. 

In an epidemic in Edinburgh, in 1818, in which 556 cases were seen by 



APPBiniKe. 



841 



Dr. Thompson of Ihat city, forty-one previously Iwd small poi. Thirty 
other CDBOs were reported to Dr. T., and of the whole Beveoty-one, three 
died, or one in Iwenty-tliree. (Maunsell on Vaccination ; Dublin Med. 
JottTn., vol. li. p. 396.) It will be recollected, however, that Dr. T. believed 
in the identity of smnll pox and chiclcen poi, and would, almost of neoeseily, 
■ee a larger share of seeond attaclis of variola than could fairly be adiDill«d 
to bear upon the queslion of the comparulivo frequency of its reeurrence. 

Dr. M6lil, of Copenhagen, records thirty-one fatal casea out of 1G3 of 
•econdary smull pox. 

Of 148 cnaea during the epidemic in Philadelphia in 1823-34, as reported 
by Drs. Mitchell and Bell, eight were in Uioae who hod been previously 
affected, and of these fonr died. 

M. Serres stated to the Freiieh Academy of Sciences, in July, 1343 (Gai. 
Mid.de Paris, Ja]y 9, 1B43), Ihat from an observation of between llOO and 
1800 cases of small pox in private practice and in hospitals, he could say, 
that eases of a second attack of Bmall pox are as numerous as of attacks of 
small pox after vnccinulion. 

In MarscilleB, in 1828, of 30,ODO persona who bad been vaccinated, 2000 
were attacked wilh small pox, and 31 died. Of 2000 who liad previously 
bad ttmall pox, twenty hnd it a second time, and four died. 

Dr. Maeiiinlosh says, lliat he knew upwards of twelve well aathentkated 
ioBtances of persona attacked a second lime with small pDX,and lluit all hia 
cases of secondary small pox, with the exception of two, were remarkably 
severe, whereas he rarely saw a severe case of sioall pox after vaccinatioo- 
{Praelice of Medicine ; Phila, edit., 1844, p. 169.) 

On the other hand, we doobt not that ttio comparative frequency of such 
recurrence has been sometimes much overrated. The Commitlee of the 
Provincial Medical and Surgical Association say, for instance, {Trani,Prot' 
Med. t^ Surg. Assoc., vol. viil, p. 67,) that, occordbg to the most aDCilrate 
calculation they can make, there cannot bo fewer llian 239 cases ttecwded 
by aiity-lwo correspondents ; and that of these, twelve or thirteen proved 
falsi. We feel conhdent tliat some allowance should be made fur errors in 
diagnosis, and perhaps for the inflnence of the probable prevalence, to » 
eonsiderable extent, of the views of Dr. Thompson, before alluded to, in 
lavorof the identity of sniall pox and chicken pox, in weighing the authority 
of the commanications lo that body, made as they were by practitioners scat- 
tered throughout tlie country ; and, perhaps, the some remark may be sppli- 
enbleloalleastaport of the writers referred to by Dr. Boron, the chairman of 
that committee, who, in liis Life of Jenncr, (vol. 1, p. 266,) says, that more 
than one hundred and thirty different writers may be named who luive 
reported cnses of secondary or recurrent smull pox, many of these being 
probably tlie same as those quoted by that commiltfe. Indeed, the very 
low rate of mortality, according to their own ligDres, is strong presumptive 
proof Bgainst the geiiuine nature of all the cases thus reported to that 
!, the deatlia having been only m the proportion of 1 ia 19.

We feel bound, &lao, freely to acknowledge the authority due to the 
opinion of our author, ho strongly pupressed in the text, in favor of (he in&e-

a. series of years, and under Buch favomble circumstaoces ; and lo record, in 
addition, tlie striking fact stated by tiim in a letter recently received, that> 
during tlie last forty-one years, but one single case of recurrent email pox 
bos been repoKed to the Medical and Chirurgicnl Society of London, the 
iant and only recorded case in their tranwutions beinv one by Dr. Batemao, 
in 1310. One cuae, adds Dr. G., did occur in London, about twenty yean 
ago, but was not reported.

The comrounication of small pox to the fcetus in Utero is not of so rare 
occurrence as to render it necetsary to addnce cases in proof of it ; but we 
inlrodnce a few to illustrate its more common phenomvaa, nnd to show th« 
relation between it and the influence of vaccination and of vnrioln oii the put 
of the mother, n rclulion by no means cunsiani, as the sequel will bhow. 

In the Amer. Jour, of Med. Sci., five cases are repdrlcd of such coomn- 
nication, in which the child was born with small pox, the mother rcauuning 
entirely free from tiie disease. 

The first was communicated by Dr. J. K. Milchell (vol. vii. p. 655.) In 
this case, the child was bom healthy, bat exhibiled symptoms of the dl^ase 
three days after birth, and nbe days after birth iho puaiules were in a stale 
of complete maturity. 

The second ease (vol. sL p. 499) was communicated to the French 
Acodemy of Medicine in Jaly, 1833. by M. Deneux. The child was covered 
at birth with confluent variolous paatulea, in the eleventli or twolfth day of 
the eruption. 

The third case (vol, iv., new aeries, Oct. 1843, p. 485) occurred lo Dr. C. 
Guoli, in a child bom June 3, 1341, covered with pustules of variola. The 
pustules appeared at iheir height on the second dny, and on the fiflh day 
maturation began, bat the child died on the ninth day after birlh. 

The fourth ease (vol. vi., new series, July, 1843, p. 210), reported and 
exhibited lo Ihe French Academy of Medicme in 18-13, by M. Gerardin, was 
that of a child born five days previously with a. full eruption of the diseue 
is a state of suppuration. 

The fifth case (reported in vol. v„ new scries, Jan. 1843, p. 349) occnmd 
in our city in 1843, in the practice of Dr. B. F. Joslio. The child had 01 " 
body at birth about 170 regularly formed pustules, apparently in the •! 
at which they would be found in ordinary coses about eight or ten dayirf

the attack. The child lived only a quarter of an hour. In this case, the 
infection was received by the mother just thirty days previous to the birth 
of the child. She was exposed but once to a single case, at the very com- 
mencement of the eruption, and for a single day. 

In the first case, the mother bore distinct marks at the time of the natural 
small pox with which she was affected in childhood. 

In the second case, the mother had been vaccinated, but had never had 
the small pox ; and in the third case, the ; mother had been successfully 
vaccinated when an infant No mention is made of the protection of the 
mother in the fourth case. 

In the fifth case, the mother had been vaccinated in early childhood, and 
the operation was repeated on the day of exposure by Dr. Joslin himself, 
but without effect 

M. Depaul met with a case of transmission of variola from a mother to 
her child, which had numerous pustules at birth, though the mother had 
visited a person with the disease a short time before without taking it 
(BuUeL de Thir,, Apr. 30, 1849.) 

A ease also occurred in the Maternity Hospital in Paris, in which the 
fkee, scalp, and different parts of the child's head were covered with the 
pustules of small pox at birth, though the mother retained titc marks of 
vaccination, and stated that she had never hod the small pox. She had hod 
DO connexion with persons suffering under the disease, but only, about eight 
or ten days before, had gone to see a patient at La Pitie, near where lay 
another patient with the small pox. (London Lancet^ Feb. 18, 1843, p. 741.) 

Dr. Mead has recorded an instance in wliich a woman was delivered of a 
dead child at the full time, covered with variolous pustules. She had 
formerly had the disease, and was attending her husband with it, when 
delivery took place. (Medical Works, chap, iv., p. 253.) 

Dr. Lebert exhibited to the Biological Society at Paris, a foetus about 
four months old, whose body was covered with pustules of variola. The 
mother had the disease slightly, and aborted during her convalescence. 
(Bulletin de TJUrap., Apr. 30, 1849.) 

Dr. King mentions a case (New York Jour. Med. and Surg., Apr. 1840, 
p. 292) which occurred in Paris, of the birth of a living child at seven months 
covered with an eruption of umbilicated pustules, the motlier having entirely 
recovered, and presenting at the time of its birth no evidences of the erup- 
tion, except the red spots succeeding the scabs ; the child having been bom 
twenty-one days since she was first attacked, or seventeen days after the 
appearance of the eruption. 

Dr. Luther V. Bell gives an instance of a lady who hod small pox in the 
eonfluent form at the seventh month of pregnancy, and escaped without 
abortion ; but " at the expiration of her full term, was delivered of a healthy 
ehild, whose abdomen and thighs were marked with decided small pox 
pittings, and who was unsusceptible of the vaccine disease." (Notice of 
Esnay oh Small Pox, Varioloid, and Vaccination, Amer. Jour. Med, Sci, 
May, 1836.) 



S60 APFUUiZ. 

Van Swieten (quoted by Dr. Hoaack) mentioiis a similar ease of a child, 
born at full time, with pita of small pox, the disease having been commnm- 
eated by transmission through its mother, who had herself long before gone 
through the disease. 

In one of Dr. Jenner's eases, referred to by our author, the mother, who 
had had small pox when a child, waa exposed to it ** a few days before 
eonfinementf the child was indisposed on the fifth day after birth, and the 
small pox appeared on the seventh day. There were but few pustules in 
this case, and they maturated completely. 

The cases of Dr. Jenner, originally published in the first volume of the 
Med, Ckir, Tranuc cf London^ and also the one by Dr. Mead, to which he 
alludes in that pi^r, may be found in the Amtr. Jour. Med. SeLf voL viiL 
p. 225. 

Cases of communication of the disease to the foetus in utero are also 
given by Dr. D. Hosack, with numerous references to other cases by difiSBr- 
ent authors. (Medical Essays, vol. iL p. Ill : also vol. iiL p. 470.) 

On the other hand, as our author remarks, the child sometimes ese^ies 
when the mother has the disease. A ease is related in the BnUelm €Untr. 
de ThSrapeuHque (Feb. 1847, p. 143), in which a child bom of a mother 
with small pox of the confluent form, and in an advanced period of desioefto 
tion, showed no marics of the disease whatever. 

It will be found on examination of the preceding and of other cases, that 
this communiciition has occurred after vaccination of the mother in infancy, 
and after her re-vaccination on the day of her exposure, and also after 
variola, both naturally and by inoculation. 

It also takes place when the mother is yet suffering from the disease, and 
after she has passed through it years prenously, and when she herself 
escapes entirely. 

The fa^tus may be infected by absorption of the virus through the 
mother without her experiencing any effect from it, or transmitted directly 
by inoculation of the mother, and may be communicated any time from the 
fourth month (and perhaps earlier) to the full time. The foetus may be 
thrown off in three or four days after cessation of motion, or may be 
retained for three or four weeks. 

The child may be covered with eruption at birth, and this eruption may 
present itself in different stages of its progress in different cases, even up to 
the eleventh or twelfth day of the eruption, or may not appear until three 
or four, or even seven days after birth. It may also be bom at full time 
with pits left by the disease some weeks previously. 

The child almost invariably falls a victim to the disease at once, or lingers 
for only a few days ; but has been born healthy at the full time, with marks 
of previous disease, and has survived, when the disease in a mild form has 
appeared after birth. 




Other meanB bcBides those mentjoned in the text hare been used for 
preventing the pitting by the puetnles of email |k)x, cither by caoaing their 
abortion in Uic forming stage, or drying them up after they hu\e maturated, 
•nd upon autliority whicli would seem to render them worthy of some 

As a general rule, the more recent the eruption, the more easily is it 
arrected. One writer thinks that the puelDlea can be arrested even after 
suppuration, and anotliec flxes the period at wbieh it can be done as lale as 
the seventh day. 

Mercury hai been used under different forms, both as a plaster and ax a 
waah. M. Briquet employs (at the Hdpital de la Chariti.-, Paris) a mask 
ooroposed of mereuriai ointment, and solidified by means uf the powder of 
■Iftrch or of fecula, which is renewed once or twice a day. A thick layer 
of it is spread with the finger over the forehead, check*, eyebrows, nose, 
lips, eara, &c., which causes abortion of the pustules, and preventa the 
■welling usually attendant upon the confluent form. (Bullelin Genir.de 
Thirap. Med. et Chimrg., torn, juxii. p. 60, Jan. 1847.) 

Prof. Bennett, of Edinburgli, also uses mercurial ointment thickened with 
starch C^. Ungt. Hydrarg. Sj, Pulv. Amyli 3ij. m.), smeared over the fiice 
Digfat and morning. (Monthly Jour. Med. Sci., Jan. 1850.) 

A compound mereuriai plaster, known under the name of " plaster of 
vigo," of the French Fharmacopcela, is a favorite application with some 
FVench physicians. 

If mercurial plaster is applied before the fifth day of the eruption, one of 
two things happens, — either the papules disappear by resolution, or they are 
changed into vesicles or into tubercles. The latter change is more rare, 
according to Af. Briquet, and seldom takes place except on Iho face. 

When the dressing is removed, small, hard excrescences, bsensible to the 
touch, are seen, which gradually fade, and disappear at tlie end of ten or 
twelve days, partly by resolution, and partly by desquamation, and without 
leaving any trace. The mercurial plaster must be be kepton eight to twelve 
days. (Repnrl by M. Briquet la French Aead. Med., Apr. 7, 1846, on a 
eommjinication by M. Cliarcellay — Oar. Mid. de Parit, Avr. 11, 1846.) 

Ptyaliam sometimes occurs from the application of mercnriol phiater, a 
case of which is given in the Renie Midkale ; the result, however, proved 
eventually favorable. 

A solution of corrosive sublimate (one grain to J vij. of distillod water, 
with 3j. of laudanum), applied by means of compresses kept wet with lE, !■ 
also said to prodnee very marked effects in causing the disappearance of 
pustules, even afler they have fully matured. 

Simple mercurial ointment is used much more fVcquenlly, both in this 
country and in Europe, tlion either the plaster of vigo or the wash of the 
bi-chloride, and is probably equally eScocJoua, It may be applied freely

with a brash or earners hair pencil. Dr. Stewardson^of Philadelphia, speaks 
very favorably of its effects. {Amer. Jour. Med. ScL, Jan. 1843.) 

Baron Larrey communicated to the French Academy the use of gold leaf 
for this purpose by the Egyptians and Arabs ; bat stated that he derired 
nearly as favorable results from repeatedly anointing the face with almond 
oil, an application which we have ourselves found grateful to the patient, 
and, to a certain extent, protective against cicatrices. 

M. Malapert recommends a solution of hydrate of potassa for this purpose, 
which, he says, dries up the pustules without leaving any cicatrices or stains 
on the skin, but does not mention the strength of which it is to be used. 
{UAbeiUe Mid, Juin, 1847.) 

Dr. Corrigan employs a coating of emplast plumbi, melted with oil of 
almonds, and laid on with a cameFs hair pencil. (Dublin Quarterly Jour* 
Med., Aug. 1846, p. 245.) 

The exclusion of light is also thought to prevent pitting. See result of 
experiments by M. Serres, mentioned in Amer. Jour. Med, ScL, Oct 18439 
p. 469. 

Dr. Crawford, of Montreal, and Dr. Samuel Jackson, of Philadelphia, have 
succeeded in preventing pitting by the application of the tincture of iodine, 
each without the knowledge of the other, the former having published the 
first account of his trial of it (Med. Examiner, Phila., Dec. 1846.) 

Sulphur ointment ( 3 iss. to 3 ij. to 5 j. lard), rubbed lightly, three times a 
day, over the parts affected, has also been recommended as not inferior to 
mercurial preparations in preventing the suppuration of the pustules and the 
scars that usually follow them. (Gaz. Mtd. de PariSj Avr. 10, 1841, p. 
232.) 

Velpeau says that if the pustules are cauterized within the first two or 
three days, and even somewhat later, no marks will be left ; and Dr. Morton, 
of Philadelphia, says that he has confirmed the truth of this statement 
Dr. Morton states that he has adopted with great success the plan of having 
the face frequently wet with spirits of hartshorn, which, he says, keeps down 
the inflammation, and prevents the pustules from becoming either large or 
irritable. (Notes to Mackintosh's Pract. Med.) 

M. Piorry recommends very highly the use of blisters for this purpose, 
and claims for them several advantages over other means. (Med. Chir. 
Rev., Jan. 1847 ; from Gaz. des HOpit.) 

Mr. Ranking suggests the use of collodion for this purpose, and the 
suggestion strikes us favorably ; but we have met no report of its applica- 
tion in this way. (Braithwaite's Retrosp., No. 19, p. 208.) 

A more extended notice of some of the means mentioned in this summary 
may be found in the third number of the Journal last quoted, for January, 
1841.) 



[G.-Pagein.] 

Others besides Sir Gilbrrt Blatie hnve drawn the same inference that he 
djd tiom the bills of mortslity of London during the lost century reepMting 
the increase of mortality by the practice of inocalatiou, an increaui which 
our author attrihutes solely to epidemic prevnience ul' the disease : and thete 
Hre alBo additional facts which would aeem 1« indicate thai ila effect hia 
been equally posilivo during the present century. 

Mr. Marshall says of small pox in London, " It was more general, and 
more severe in ite charoclcr, and caused greater mortality after the introduc- 
tion of inocuktion, until tlio time of the introduction of vaccinatioD." 
(MoTlalily of Ihf MttTopdii frojn 1639 20 1S21, by John Marshall: iMndimr 
1833.) 

According to Uie "Report on the Protective Powers of Vaccination" by 
DrB. Cundie, Hewson, and Afoore, of Philadelphia, vnriolous inoculation woa 
prohibited in that city in 1811 ;, and for four succeeding years, not a death 
from amall poi was reeorded. According to the same authority, for the 
period of sixteen years terminating with 1801, the proportion of deaths by 
small poK to the whole mortality was 73 in 1000. From I SOT to 1811, the 
proportion was 40 to 1000, during which lime vaccination was practised j 
and from 181 1 (when inoculation was abolished), tlie pruportioniil morlallty 
has been reduced lo I8> 1000,; {Medical Examiner, Phihi., Jan. 1847, 

^39.) 

Reference to the tables in the Appendix (B) will Bhojf that small pox 
has prevailed epidemically several times since 1811. 

Mr. Wylde says that "the superiority of vaccination over inotnlation ia 
ahown by the fact that umall pox mortality is highest in tho^e provinces 
in which inoculation is moat practised, and vaccination leasL" {Dr. Wat* 
Rrport—Bril. and For. Mtd. Rev., Oct, 1845, p. 581.) 

Dr. Baron saya (Life nf" Jenncr, vol. L p. 260) " tlic practice of iaocnlation, 
the greatest improvement ever introduced in the treatment of small poi, 
atlhough beneficial to ihe person inoculated, has been detrimental to man- 
kind in general. It has kept up a constant sonrce of noxious infection, 
which has more than counterbalanced ihe advantages of individual swurily." 

Sir Gilbert Blane says that ttie diifueion of snuill pox by inoculation was 
more Btrongly exempliRed in the country than in London ; Kince there ore 
many places where small pox was not known for twenty, thirty, and even 
forty years, in which at present scarcely au ndnlt can be found who has not 
had it In this case, however, wo musl make due allowance for epidemio 
influence, which has doubtless contributed very much to its more general 
<Uffb^n. 

Besides, we cannot think that there would have been such nnanimity in 
diffcrtnt counlrics in abolishing the practice, and, as in Great Britain, uitb 
the altachment of a heavy penalty to ila exercise, hod not the evidence in 
bvor of such a measure been of the most decided character. 

We learn tioD) Dr. Baron {Life r^Jenner, vol. I p. 334) that the practic* 



854 AFFEIDZX. 

was prohibited in Paris, by royal authority, in 1763, in consequenee of its 
being foand, on investigation by the police, that the infection was multiplied 
and diffused by its means. Also, that in Spain, where the practice was 
scarcely ever admitted, small pox has caused less mortality in proportion to 
the population than in any other country in Europe. Dr. R also states 
(p. 235) that in 1768, the Empress Catharine of Russia submitted herself 
and her son Paul to inoculation, and that this spread the practice among the 
Russian nobility; and the disease prevailed so extenmvely, that Sir A. 
Crichton, subsequently the imperial physician, has stated that, previously to 
the adoption of vaccination, every seventh child bom in Russia died annually 
of small pox. 

There seems also to be some discrepancy of opinion respecting the rate 
of mortality after inoculation. Our author states it to be, with ordinaij 
precautions, one in five hundred. Though we perhaps might have hoped 
that improvement in the mode of conducting the operation, both in the 
preparatory and accompanying treatment, the selection of the proper season 
of the year, &c., might have led eventually to a diminii>hed rate of mortality, 
still we fear it rarely descended to so low a figure. 

Dr. Jurin concluded, from an examination of the London bills of mor* 
tality for forty-two years, that of those who had been inoculated, one in fifty 
died. 

According to Mr. Shattuck (Viitd Statistics cf Boston — Amer. Jour. Med. 
Set., Apr. 1841), the deaths among those who were inoculated in that city 
between the yea'^ 1721 aiul 1792, amounting to nearly 23,000, varied from 
five in a ihous^md up to tliirty in a thousand, the smallest mortality thus 
reaching one in two hundred of those inoculated. During the same series 
of years, the deaths by natunil small pox ranged from the proportion of 95 
in 1000 to that of 34 1 in lOOO of those attaoki^. 

In addition to this, we must not overlook the permanent disfigurinff of 
many, the danger of loss of eyesight, and also the liability to be followed 
by diflorent chronic disea«»es. 

However great, therefore, may be our indebtedness to inoculation for the 
amount of life saved bv it to mankind, and we freely acknowledcfc it to have 
been great, we cannot but feel that the practice can never be relieved from 
tlie objection of multiplying foci of contagion ; and, while we concede that 
its continued employment would doubtless have led to great improvement 
in the mode of conducting it, and to still more decided benefits from it, with 
probably diminished risk of communicating it beyond the individual operated 
upon, we cannot be too grateful for the substitution of another protective 
power, apparently equally eflicacious in its results, and almost entirely free 
from the charge of the least danger in itself, either to the individual or to 
those about him. Not that we love inoculation less, but that we love 
vaccination more. 

At the same time we fully agree with our author that there are circum- 
stances which would warrant its adoption in special cases, and with proper 
restrictions, and that those mentioned by him come under this head ; and we

The difTeTeal views which have been entertained respecting the pathology 
of the dropsy follomng scarlet fever show that the subject, allliough it has 
received much attention, still requires further investigation. 

Some ehor^ it upon the akin, whoae funclions aa an emunctory ore aaid 
to b« impaired, according to some, by the simple action of cold, and aecord- 
ing to others, by the specific poison of the disease ; while another ascribes 
it to a sub-infiamnjation of tlic cellular texture originating in the eruption. 
Others again attrihule it to general debility of the ayatem. 

Dr. Qolding Bird thinks that the seqaelce of acarlatiiui ore " almost oil 
loferrible to the retention of the nitrogeniied elements of urine in tike 
blood," to which he attributes the tendency to the setting up of eerona 
inflammalion, especially of the pericardium, pleura, and arachnoid. 

Ila connexion with an albumiuous statu of the urin«, at leoat in s great 
nuqority of cases, has led many later pathologists to place tlie seat of it in 
the kidney ; but even among those who have token this view of its origin, 
there is discrepancy of opinion as to the exact port of tlie organ ufleuled. 

Dr. George Jolinson regards it as dependent upon an inflammution of the 
kidney, very umilar to that stute of the skin which results in desquamation 
of the cuticle. lie calls it "actUe daiiuamalive nephrilu," He eaya that 
this desquamative ataio of the secreting cells may exist some time before 
eridenou of congestion of the kidneys appears. When tilts desquamation is 
the tubuti urioiferi may become choked with epitiivlium, and 
may thns be produced, and this may be followed by infUinma- 
tion. {Med. Ckir. Tratu., vol. xxz. 1S47.] Dr. West takes tlio same 
view of the notivu character of the inflammation. 

Dr. Sohilnlein is of the opinion that the exfotiation of the urinary epithe- 
linm is the prodlBposing cause of aoariatinal dropsy, and says that tha 
patient {a not Hnfe ao long as any of Ihia deposit ia found in the nrine. 

Dr. James Miller conaiderv the dropsy as " a port of the disease, or merely 
an evidence of another, but less obvious expression of the acarlatinal poison 
in the human body," and aays that " it is no casual complication or sequel 
utaing from undue exposure alone." He contends that the poison has a 
primary influence on the kidney, and affects it according to definite lawa, 
•hewing itself then, as a geaerol rule, on the fourteenth and lwenty4int 
dajSi— «id tays that this ordinary period of the Mcanence of tenal aym^

toms ** IB probably in accordance with the normal action of the ecarlatinil 
poison Btill active on the kidney." The eruptive action is sometimes 
wanting, and to this form Dr. M. gives the name of " renal scarlatina^ or 
scarlatina of the kidney s.^^ 

Dr. Bchrend describes two forms : — the first dependent upon congestion 
and inflammation of the kidneys (Hydrops nephriticus) ; the second upon 
debility, or impoverished state of the blood (/f. antcmicus). In the first 
form, he thinks that the dropsy is partly a direct result of the impediment to 
the eliminative process of the skin, and of the efforts of nature to restore 
this, and partly a consequence of the impediment to the excretion of urine 
by the kidneys. To the latter cause he attributes the effusions into the 
serous cavities ; while the dropsy of the cellular tissue seems to be a sequel 
of the renewed attempt at elimination by the skin. For a sumouuy of his 
opinions and his conclusions, see Ranking' s Abstract^ No. 10, p. 28. 

Some support of the opinion which refers it to impaired function of the 
skin itself, at least occasionally, would seem to be afforded by an epidemk 
of scarlet fever in Berlin, in 1840, where, in a great majority of cases, the 
urine was not albuminous. 

On the other hand, the deposits of epithelial cells and ** fibrinous casts** 
of the tubuli uriniferi found at times in the urine, would seem to fiivor the 
opinion of infiammation of the kidney as the primary form of the disease. 
This hypencmia or inflammation of the kidneys is doubtless the cause of 
the albuminous urine, which may disappear as that condition of the organ is 
removed ; or it may become acute nephritis, with effusion of fibrin or pus; 
or may piiss into the confirmed albuminous nephritis of Rayer (Brighfs 
disease). 

Hence, in fatal cases of scarlatinal dropsy, we find after death evidences 
either of simple congestion, or of inflammation in different stages of progress 
in ditferent cases, from the earliest to the most advanced stage, and even 
abscesses in the kidney, and in protracted cases, tlie well known lesions of 
Briglit's disease, instances of all which clianges arc on record. 

Dr. R. B. Todd considers the conditions of dropsy after scarlet fever to be 
— 1st, a j)arlicular state of the $kin ; lid, a particular state of the kidney ; 
and 3d, a particular state of the bjiml ; and says that he does n(»t think you 
get the dropsy fully developed without the concurrence of all three con- 
ditions ; that if one of them is absent, you niny have a threatening of the 
dropsy, but the full result does not follow. {I^md. Med. (;«:., Feb. 1849.) 

Mr. J. W. Trii)e acknowk'dg«^s three varieties of scarlatinal dropsy : — 1. 
That in which the urine is not alljuminous. 2. That in which it is albumi- 
nous, with subacute nephritis. 3. That in which the urine is .albuminous, 
with acute nephritis ; or dropsy from debility, dropsy from renal derange- 
ment, and from disftrganizati(»n. (M(dirnl Tiriics^ Oct. 21, 1848.) 

Chanm-s occur durinir this, as wt-ll as during' many other acute diseases, 
which give rise to dropsy, especially in protracted crises, as is seen in 
phthisis, in convalescence from fever, malarial diseases, &c., when there is 
no reason to suppose that there is any affection of the kidney. But when 



APFESDIX. 357 

dropsy supervenes early, and particularly if it comes on suddenly, and 
iq>pear8 in the face first, and the patient shows no decided evidences of 
debility, there wUl be good reason to look to the kidneys as the cause. 

[ L^Page 201. ] 

The treatment of the dropsy following scarlet fever may be described 
under the two heads of prevenlive and curative^ the former, as our author 
remarks, always of course to be aimed at 

Among preventive measures may be mentioned careful protection of 
patient from atmospheric changes, a regular diet, a free state of the bowels, 
and especially the frequent use of the tepid bath. The symptoms men- 
tioned in the text as precursory of effusion, must be carefully watched, and 
also the first indications of its appearance, which may generally be earliest 
detected in a puffy state of the eyelids, and an oedematous condition of the 
faiteguments of the cheeks, particularly about the lower part of the face. 

The treatment of the effusion, when it has once supervened, must depend 
upon the length of time since it appeared, its extent, its manner of appear- 
ance, whether slowly and gradually or rapidly, the constitution of the 
patient, the previous treatment, his condition at the time, and the nature of 
the prevailing epidemic. A careful attention to these several points, and 
especially to the condition of the patient at the time, will often enable us to 
decide upon the proper plan of treatment in a given cose, and will also 
reconcile the apparently contradictory statements of those who recommend 
on the one hand an antiphlogistic course, and of those who, on the other 
hand, insist upon the necessity of tonics, each plan being proper under 
eertain circumstances. 

The leading indications of treatment of this form of dropsy may be stated 
to be — 1, to relieve the congestion of the kidneys ; 2, to remove the accu- 
mulated fluid ; 3, to promote the action of the skin ; 4, if necessary, to 
•upport the tone of the system. 

The principal means to fulfil these indications are : 

1. Cupping, leeching, poultices, and fomentations; 

2. Ilydragogue, cathartics, and mild diuretics ; 

3. Diaphoretics, tepid bath, warm diluent drinks. 

4. Tonics of different kinds. 

In the early stage, and when there is a decidedly inflammatory state of 
the system, with a hot and dry skin, &c., and the patient is of a strong 
constitution, and the urine is highly charged with albumen, and the more 
BO if it contains blood, depletion from the lumbar region by means of cups 
or leeches, followed by emollient poultices, may be called for; Jind in 
patients over six or eight years of age, it may even be necessary to take 
blood from the arm under such circumstances — but, as a general rule, the 
abstraction of blood, either locally or generally, may safely be dispensed 
with, and the application of poultices and fomentations be trusted. In this 
■tate of things, diuretics must be avoided, and the internal means restricted 



358 AFPBHmx. 

to catliartics, diaphoretics, and emollient drinks. This coarse will be tlie 
more called for, if the effusion has taken place suddenly. 

In other cases, when the constitutional disturbance is slight, and the 
effusion has taken place gradually, and the patient is not enfeebled, hydnu 
gogue cathartics, with mild diuretics, and light diet, as mentioned by our 
author, will be all that is required. Among such cathartics, the combination 
of jalap and bi-tartrate of potassa is probably one of the best Elateriom is 
also valuable, when more prompt action is necessary, and the effufflon 
requires more immediate removal, and may be given in doses of i to i of a 
grain, every three or four hours. Castor oil may also be used, if these are 
tardy in their action. We have derived very decided benefit from the use 
of the apocynum cannabinum (Indian hemp) in cases of abundant effusion, 
when there was little or no febrile action, and have seen it act freely, both 
as a purgative and diuretic. 

In still milder cases, the iodide of potassium presents us with a good 
alterative and diuretic, and may be given alone, or in combination with some 
bitter infusion ; and when the system is much debilitated, and especially in 
those of strumous diathesis, iron constitutes a very valuable addition to our 
therapeutic means, and may be given in the form of iodide, citrate, or, as 
highly recommended by some, muriated tincture. In these cases, the diet 
should be generous and full, but carefully adapted to the state of the diges- 
tive organs, and the bowels kept in an open state. 

The acetate of lead lias been recommended bv some, after the active 
symptoms have subsided, when the kidneys are in a stale of passive conges- 
tion, and a kind of serous lurniorrhage is taking place. 

I)iaj)li(»r<''iics are also used with advantage, and may be combined with 
diun-tii's, a.s the syru]) of ipecac, with acetate of ammonia, and sweet spirits 
of nitre. 

To any and all these means, the tepid bath will be found a valuable 
auxiliary, and may be given every second or third evening, of the tempera- 
ture of I'li^ t(» 91^ Fahr., and the child kept in it from twenty to thirty 
minutes. 

The cure is taeilitated by keeping the patient in bed, and also by directing 
the constant use of llannel next to the skin. 



[ K.— iVgf 226. ] 

We have thought that our readers would be interested by a >hort abstract 
of some of tiie leading l\'ature& of erysipelas in an epidemic form, as it has 
presentid itM*lf in dillerent plaees in our country, remote from each other, 
during the past eight or nine years, and has been deseribed by dilTerent 
writers under the ditlerent names of "K])idemic Krysij>elas," ''Erysipelatous 
Fever," as well as under the j>opular name of " Black Tongue," a name 
which one form of it has received in some parts of the Uni<ui. 

The earli«'st account of erysijH'las in the form of an epidemic, within the 
period alluded to, which we have met, is that given by Drs. C. Hall and G. 



369 



J, Dexter (Anur. Jour. Med. Sci., Jao. 1844) who dewribe it under the 
mune of ■■ eiyeipelulous fever" at it occurred in tliu nortlieru section of 
Vermont and New Hampshire, in the years IS'U—IS. In Ibis ejndenuo, 
there was great nniformity in the mode of nttuck for two or three moalhi 
from its first appearance. Afler premonitory ■ymptoms of pyrexia, with 
nore or leas soro tbroat, enlarged loadls, and eub-maxjllary glands, difficult 
degliititioD, and aometimes pAinfui respiration, attended with Issaitude, pain 
in the back and Umba, fro()uent and depreHsed pulse, cold and clammy honOB 
and feet, &c., &c., and generally at the end of twenty-four hours, there wae ft 
chill, sometimes a severe rigor, followed by general reaction, with frequent 
ud bounding pnlae; and in some inaUncos, the skm was bnlhcd with a 
copious acrid perapiratioo. In other eases, the attack came on when the 
patient was in apparent health, without an; premonitory symptoma, with n 
sense of coldness, soon followed by severe chills. These were succeeded 
by pain in the head, stomach, abdomen, back, and joints, or some or all of 
these at the same time, followed in the course of twenty-fonr or tMrIy-«ix 
hours by the soro tlirout. The utysipeUtoDS affection of the skin usmatly 
appeared about the third or tourtli day ; and when it did appear, was not 
conflned lu any particular location. It 
side of the neck or fact', prcsciiling an i 
rod spot. 

In this epidemic, there wa« n marked c 
pnerpeml peritonitis, and striking cases ai 

was commnnicatcd to parturient females by physicians In attendance o 
oases of erysipelas. The puerperal disease proved very fatal. 

In one county in Vermont, of thirty cases of puerperal peritonitis which 
ooonrred, only one recovered ; and in Balh (N. H.), containing a population 
of 1500 or 1600, twenty mothers died from puerperal perituiiilia, and ahont 
forty with erynpelas. 

Diaphoretics, anodynea, hot fomcnlatioiia, and counter-irrilants, were 
fonnd the most useful means of trealmenL In some casus with great beat, 
ftill, bounding, and frequent pnlse, pain in the head, back, and limbs, and 
•xtreme thirst, prompt and efficient bleeding was the only remedy to be 
depended upon ; but it waa ncceBsary to employ it early. Different opinions 
were enterloined respecting venesection by practitioners in the same neigh- 
borhood in this epidemic, but the general impression was against it, except 
in the class of cases just referred to. 

In the stage of collapse, quinino was given with much success, wilfa 
diSiiaible stimuli ; and when low muttering delirium supervened, opium, with 
tartrate of antimony, had a very excellent effect. 

The same form of erysipelas, with afll'ction of the throat, ooenrred in 
Middlebury (Vermont) in tlie winter of 1841 and 1843, and has bc<en 
described under the name of "eindemic erysipelatous fever" by Dr. J. A. 
Allen in the Bo^on Med. and Surg. Jour., vol. Ttxix. 1844. The throat was 
niuformly found inflamed, and the tonsils swollen, sometimes to such an 
extent in ■ few hours that deglutition could only be performed with 



usually first observed o 
:utely sensible and circumscribed 



between the disease and 
which this latter disease

extreme difficulty. The tongae became so much enlarged in some cases as 
to fill the mouth, and prevent the passage of anything to the stomach. Bat 
this was rather a rare occurrence. In the course of a day or two, the 
disorder of the throat and mouth became mitigated, or entirely gone ; and in 
proportion as the local affection diminished, the face, scalp, or side of the 
neck became swollen, painful, hot, and vesicated, presenting the unequivocal 
characteristics of erysipelas. The local disease in some cases attacked the 
brain, in others the lungs, in other cases the abdominal viscera, and occa- 
sionally the soles of the feet, ankles, or palms of the hands. 

The number of cases in Middlebury was estimated at about tax hundred 
and fifty, with a population of about 3,200. A few cases occurred in 
November and December, 1841 ; but by far the largest number occurred in 
the next two months. Thirty-four deaths were caused by it between the 
first of January and the latter part of May, 1842. Puerperal peritonitis 
assumed an erysipelatous character, and added to the mortality, both in this 
epidemic, and in an epidemic of erysipelas in the same town in 1825-6; 
five cases occurring in the former, and all fatal, and seventeen in the latter, 
of which only two survived. 

In 1826, there were not less than sixty cases of parturition in Burlington, 
and in 1842, not less than twenty. ^ Hence,'' adds Dr. A., ** at each time of 
the prevalence of the epidemic erysipelas^ one fourth of the obstetric cases had 
the child-bed fever.*" In the winter of 1841-42, at Crown Point (N. Y.), 
two physicians had over sixty cases of delivery, and of these, fifteen or 
sixteen had puerperal fever, and died. 

Venesection was found of the greatest value in this epidemic, when there 
was great vascular action, or congestion of any vital organ ; but was prac- 
tiseii in only a minority of the cases. Diaphoretics, witii external warmth, 
were found useful, and among the mo^t valuable means for acting on the 
skin, wjLs pulvis antimonialis. Dr. A. derived no particular benefit from tlie 
use of calomel as an alterative. 

The same fever also prevailed extensively at Moriah (S. Y.), a town 
about twenty miles from Middlebury, in 1842, at the time it was most rife 
at this latter place, and it was estimated that nearly a thousand cases 
occurred there. It also prevailed in the neighboring towns in the winter of 
184*2- 13. From what Dr. A. observed, he dt'duc«d the conc]usi(m that 
" w7j' 72 it haa oiicc cxpcjuhd ilself in a place, lilhiirf, or vt'ij^hhorhHnl, it will 
not rcrur (la^nin in the sarn^ placf for a i^frirs of ijrnrs ;" also, '* that those 
individuals irho hive had it at one cpiJemic jMriod are. exnnpt from its influ- 
ence' at its nej't occnrrrnc.^^ 

Dr. GcorLTc Sutton, of Aurora, Indiana, publi>hed (We<tfrn LanctL Nov. 
1843) nn account nf tlie disease as it appeared in Ripley and Dearborn 
counties of that State, in 184'2-43, under the name of '•Epidemic Erysipelas, 
known by the popuhir name of ' Bhick Tongue.'" The epiileniic assumed 
different chnrncters, one of which was an erysipelas, connected with 
cyniUK'iie tonsillaris, or swelling of some of the lymphatic glands. Another 
was a typhoid pneumonia, sometimes connected with swelling of the axillary 



am 



givids. Ho Bays the premonitory symptomB in each disease were alike, 
tad the chnroclcr of the fever the same ; and that one form of disease often 
changed into the other, and the two forms frequently attacked different 
mombera of the same family at the siime time. The uttaek Viaa always 
uahered in by a cliill, lasting in some caaes four or five hoar?, nAur premo- 
nitory symptoms for two or three days. *■ This was followed hy a high 
fever, swelling of the tonsils, submiuillary, parotid, and lymphatic glands of 
the neck ; noumlgic pains, darting over the side of the neek and hend, 
fi^quentiy following the temporal artery ; the tongue, covered at first with 
a thick, brown coat, soon became swollen, and often very dark in the centre i 
dcglotitjoa fVeqnently very difficult ; pulse generally very full, though eaaily 
oompresBcd ; skin at first hot and dry, becoming moist, and continuing so 
after venesection. Sometimes the mild form had only the appearance of 
Cjmonche tonsillaris. But in the more malignant form, when the throat was 
affected, after the above symploms had contitiued for two or three days, 
and Homelimes from the very commencement, the pharynx becatno of a 
dork purple color ; this color generally spread over the palate, tongue, and 
sides of the cheeks, the tongue becoming very much swollen, assuming a _ 
blockish brown color; deglutition in many eases was almost impoe.'<ihte. 
In most of these cases, an eryBipelas would commence at the angle of tiia 
mouth or nose, and spread over the face and heed, with all the symptoma 
peculiar to that diseaso." "In nearly every case," he says, "the throat 
became loelt, iphik the erytipelas was tprtading over the ikin." TTib diaeaae 
seemed sometimes to commence in the frontal sinnses end antrum. There 
would then be a discharge of large quantities of water from the nose, and the 
foce would swell so inuch as to close the eyelids. These symptoms gradu- 
ally continued until an cry^pelasmodeitsappearBnce, or there was a copious 
discharge of bloody mucua from the nose. In a case of this kind seen by 
Dr. Sutton, the neck woa unormonsly swollen from the left ear down to the 
atemnm, without any redncas of the skin, and but little inflammation of the 
pharynx; this swelling rapidly Buhsided, and was Toliowed by a profound 
coma that terminated in death. " In a number of caxei, the inguinal 
glands were the seat of the disease, becoming very much Inflamed, and 
an erysipelas first making its appearance there, and spreading over the 
abdomen." 

The treatment of the epidemic at the commencement of the attack wia 
strictly antiphlogistic, bearing in mind the tendency it had to asEume a 
typhoid character. Blood was drawn from a large oriticc, with the patient 
in (lie upright position, until a decided impression was made un the system, 
and this was generally produced by taking a few ounces In pneumonia. 
When the tliroat was attacked, emetics, followed by mercurial calharlica, 
nausennls, blisters, liniments, and sinapisma to the throat, pediluvin, acidu- 
lated and pepper gargles, scarifying the lonaila, and when the throat was 
olecniled, the application of a solution of nitrate of silver, was (he course 
generally adopti-d. and in a lai^e number of cases, the bleeding, the emetic, 
and the mercurial cathartic cut ahort the disease at once. Great eantion 



■ 



362 APFEIIDIX. 

was required in giving mercury, care being exercised to avoid its spedfie 
effect 

When the erysipelas appeared on the skin, alterative doses of calomel 
and ipecac, (carefully avoiding ptyalism), followed by saline cathartics and 
antimonial diaphoretics, were used in the robust ; and wine whey, carbonate 
of ammonia, Dover's powder with calomel, followed by gentle laxatives, 
when the disease assumed a typhoid character. As a local application to 
the erysipelas, a solution of the sulphate of copper, and also of the sulphate 
of iron, appeared to produce good effects ; and when the skin was not 
blistered, the spirits of turpentine answered very well. 

The fatality of the disease varied very much in different places, in some 
townships being very great. In several places it was accompanied by 
puerperal fever, which was also very fatal. 

Dr. Sutton was unable to give any statistics of its mortality, but says 
that it was generally considered by the oldest inhabitants to have been the 
most fatal epidemic within their memory that has visited our country, not 
even excepting the cholera. (Quoted in Amer. edit of Nunneley on Erysu 
^felas ; and also in Amer. Jour, Med, ScL, Jan. 1844, p. 247.) 
^ In an account of "epidemic erysipelas" at Michigan City (Indiana), in 
1843-44, given by Dr. Meeker (Illinois Med. and Surg. Jour,., June, 1844, 
quoted by Amer, Jour, Med. Sci., July, 1844, p. 273), of sixty cases, one 
half were fatal. In this epidemic, the skin alone was affected in some 
cases, with the mucous membrane of tlie fauces ; and in other cases, the 
internal orj^ans became intiamcd, withont its making its appearance upon 
the surface at all. It attacked nearly all puerperal females, not more than 
one in ten e.sca[)inpr. The rate of niurtility in tliese cases is not stated. 

In an cpiclcmic which occurred in Petersburjxh (Virir.), during the winter 
and si)rinjL,^ of 1814-15, described by Dr. Peebles under the name of 
"epidemic erysipelas'' (Amer. Jour. Med. Sci, Jan. 184())? to which we 
have alren<]y alluded in the body of the work, "the disease presented three 
distinct varieties, or «^n-ades of violence. First, simple erysipelatous fever 
characterized by the peculiar throat atVection, accompanied by enlargement 
and tenderness of the t,dands of the neck, and stiffness of the cervical 
muscles. Secondly, to these symptoms, usually coming on with a chill of 
greater or less violence, there was after the third or fourth day superadded 
the external erysi|)elatou8 inflammation, generally on the face and s<'alp. 
Thirdlv, the disease assuniiufr totally different features, much increased in 
severity and danger, was tirst manifested in the form of severe inflammatory 
action located in some important internal organ, wiiich symptom was only 
ultimately relieved by the apj)earance of the cutaneous inflammation." The 
internal disease was always located in the mucous membranes, and was 
liable to seize that in the lungs, including the larynx, and the miimte 
bronchial ramiflcations, that of the stomach and bowels, and of the bladder 
and urethra. 

Dr. Peebles states that it was invariably the case in his practice in this 
epidemic, as was also true in that described by Dr. Allen, that the symptoms 



or the interns] afibetion were relieved or were speedily removed by the 
appearance of inflammHtion on tlje surface, which iDvariiibly toolt place id 
■U Ihe moat severe and malignant cases of the diseasB. 

Dr. Daniel Dmlie ilIso gives a general acuount of a form of eryupclas 
known under the name of " Black Tongue" whkih prevailed b MiaViMip^ 
and Missoari in 1841, founded entirely on verbal aecounta of fixe disease 
derived from diflerent practitioaers in those stateo with whom he held 
persona] comniunicatJOD. He says that it ofiecta both wliilea and blaoha, 
the latter perliaps more frequently and fatally than the furmvr, and occurs 
in both winter and summer. In some cases, the local, and in otlsers, Ibe 
conslitulionol symptoms appeared Itrst, but the fever has always preceded 
the cattincouB inflamniation. In some oasea, the stomach instead of the 
throat was the seat of the disease. As the eryHipelsa appeared, the angina 
generally erased. In some eaaos, the tongue was so swollen and inSamed 
u to make glossitis tbe prominent part of the disease. Dr. Dralce conndeiB 
the diaenao to be a compound of erysipebs and scarlatina, Ihoogh be does 
not reg^ such a conclusion as eatitblished. The brain, lungs, and aloraaeh 
and liowels, were sevemlly the subject of the disease in diflerent ensus. 

The Uncet was employed with advanUge in the early stage of the 
diBease, especially when the brain, or lungs, or any of the abdominal viacem 
were attacked. Csthartics were generally employed, but not in large 
quanliliuH, and eopioui putting waa not on the whole beneficial. When 
exhaustion came on, as was the case in many instances after the first few 
days, diffusible stimulants, with tonics and nutrients, were required, and 
were found useful, especially in extensive suppuraUon, and with a tendency 
to gangrene. Vaiioua local applications were used by different practitiouera, 
and all with an equally equivocal beneGL {Watem Jour, of Med. and 
rSur^.,Oct. 1844; quoted in BtiHtlm of Mtdkal iScience, Nov, 1S44.) 

The some disease, as it o<%urred in Warrenlon (Miss.), in March, IS44, is 
deacribed under the same name by Dr. W. R. Puekett of that place, and 
presented tlie some general characteristics as the form which prevailed 
elsewhere, presenting similarly great diverwty in mode of invasion as well 
aa in its points of atlacli. (iV«tf> Orleaiu Mfd. Jour. ; quoted also in Buil, 
Mtd. Sci., Nov. 1844.) 

This disease also prevailed in Delaware county, Pennsylvania, during the 
spring And early part of summer of 1841, in a severe form, and Is described 
under the name of " epidemic orynpelaa," by Dr. Jesse Voang. It generally 
came on with the usual symptoms of catarrh. The ciyMpetatous indamma- 
tion appeared on the surface at the end of three or four, and frequently 
seven and eight days aAer the commencement of Ihe constitnlional symp- 
toms, but without any regularity in this respect. When it came out in 
patches for a short time, and then receded, wiilch it was very apt to do, the 
patients rarely recovered, no Iroitment having any effect in such cases. 
When tlio efHorescencc came out and remained on the sorCice, the patient 
generally recovered at thu end of from one week to three or four. Tbe

efflorescence appeared often on the head and face, but frequently on the 
extremities, or some part of the body. 

The plan of treatment found most efficacious connsted of emetics of 
ipecac, and ant. tart combined ; afterwards cathartics of calomel, followed 
by jalap or some other purgative, in a few hours ; and after free evacuations, 
mild diluent drinks of different herb teas. The lancet was freely used in 
the earliest cases, but with unfavorable effect ; and all agreed, after more 
familiarity with the disease, that ^ venesection was a dangerous, or at least 
a very uncertain, expedient" 

When the disease did not receive early attention, the patient sank from 
day to day, until great prostration ensued, and sometimes the erysipelatous 
surface was attacked with gangrene, with extensive sloughing. In such 
cases, tonics, with powerful stimulants, were required. 

The writer states that " quite an unusual number of deaths occurred,** 
but most of them in the early port of tlie epidemic, but gives no statistics. 
(Medical Examiner, Phila., Sept 7, 1844 ; quoted by Amer. Jour. Med. 
ScL, Oct 1844, p. 646.) 

Dr. Lovelace describes the ** black tongue" as it appeared in Vicksburg 
(Miss.), when it was first observed in March, 1844. He and his partner 
saw forty-two cases, of which six terminated fatally. Blood-letting did 
not answer in that epidemic. (New Orleans Med, and Surg. Jour., Sept 
1846, p. 190.) 

Dr. A. M. Keller gives cases (Western Jour. Med. and Surg., Oct. 1845) 
of " erysipelatous laryngitis" or " black tongue," occurring in Courtland, 
Alabama. 

Dr. S. Glisson also, in a letter to the editor of the New York Journal of 
Medicine, dated Livinijfston, Michigan, June 20, 1847, speaks of a form of 
"malignant erysipelas, commonly called Black Tongue," which, he says, 
had been lately observed in the neighborhood of that place. He says " the 
black appearance of the tongue has not been noticed more than once, p«^r- 
haps, out of ten cases;" but that it looked more as if it had been boiled. 
There was also very great tumefaction of the face and scalp, and also of 
the fauces, palate, tt)nguc, &.c. He says the disease proved fatiil in many 
cases, but gives no statistics. 

The treatment which appeared most successful was the sthnulating and 
diaphoretic. The anti|)hh)gistic made but little imprfssion, and the patient 
soon frll into a typhoid state, which rendered stimulants necessary. {\ew 
York Jffiir. MfiL, .luly, 1847, p. Ii27.) 

Dr. II. \. Bennelt lias given a description (\cio York Jour. Med., Mav, 
1848) (if an ''epidemic erysipelatt)us fever," as it occurred in Bethel, Fair- 
field county (Conn.), from the middle of \ov. 1837 to the middle of March, 
1818. Tht* disease resemlded very strongly, as Dr. IV remarks, in its 
general sym[)toms, local IcNions, and the mort.ility attending it, the charac- 
ters which it has presented in other portions of the country. Great 
uniformity existed in the premonitory symptoms. A very constant, and Dr. 



865 

B. thinks, a nnlform se&tof infliiiDmatio[i,waa the throat, presenting diBbrtsnt 
nppeariDcea in different individuals. " In all es«es without exception, there 
was more or less tenderness and Bwclling or L'itlier the Buli-rooxilbuy, 
parotid, or lympliatic glands of the nerk, as well as of the tonails ; and the 
uvula was almost as universally elongated." The erysipelatous efflorescence 
occurred in one sixth of the cases. 

The ages of the patients, in fifty-nine cnaes of wliich a liblo is giTctii 
varied from eight to seventy-Gve yeors, and llie duralion of ihe diBeaae from 
three days to aa many months, including the milder cases of angina 
extreme, and the cases of pectoral abscess on the other. 

In this epidemie, the scroaH membranes were a frequent seat of tbft- 
disease, especially the pleura and peritoneum. 

Dr. B. inclines to the opinion of the conto^ons nature of Qie 
with certain restrictions, but thinks tiint the evidence of fomitic contagioil|. 
with reference to the puerperal cases is very neogre. 

In the treatment of the onginose cases of the disease, t>r. B. commeneed 
wtlh an emetic of tartarized antimony, taken with a strong decoction of 
enpaloriam. This was followed by a blister to the neck, and Bometimea a 
strong solution of nitrate of silver directly lo the inflamed mucous surfaces. 
In more nmh'gnant cases, he depended mainly upon hark, with serpentine 
snd mild laxatives during the fir^t sUges, and the more powerful sllmulanta 
afterwords. He abandoned all external remedies except cooling lotions,

That the ground taken by the earliest vaccinators, and among them the 
Immortal Jonner himself, that vaccination is a perfect protection of the 
fljstem through life against variola cannot now be majntniiied to the letter, 
is almost universally acknowledged. The extent of the protection nfibrdod 
by this precious gift to man, the causes which interfere with its entire 
protective power, and the means necessary to n-move the obstacles in the 
way ofsneh protection, are not so well agreed upon. It must be conceded 
that cases of a modified form of variola ore occurring, and apparently with 
somewhat increasing frequency, in ibosu supposed lo be protected by the 
process of vaccination ; but it is consoling to notice, tlint even witli this 
increased A«quency of attack, there is a mildness which divests it of very 
much of its dread, and a mortality which, compared with that in the 
unprotected, is slight — and there is much reason In believe lliat the fatality 
does not increase in proportion to tlie frequency of attacks, and that tlie 
rate will be foand not to reach that of seven per cent, aa furnielied by the 
Btatistics of the London Small Pox Hospital. 

We have collected statistics bearing on this point IVoni different and 
distant sources, which would serve to prove that, st least under certain 
circumstances, and, perhaps, we may with propriety any, as a geuurnl rule, 
this ift tlie case. 

At the same time wo would premise, that bstnncea are recorded where

the mortAlity has reached a higher ratio ; bnt they are so few in number, 
that their very rarity affords fair ground for the question whether some 
peculiar circumstances may not have operated in the case. 

The replies received by the Committee of the Prov. Med. and Surg. 
Association would seem to place the matter in a different light The only 
two statements at all conflicting with the general favorable tenor of these 
replies was that of one gentleman, who stated that of nearly one hundred 
cases attended by him the previous year, one half were after vaccination ; 
and of another, who reports that of eighty cases of small pox, sixty or 
sixty-one had been vaccinated. In the latter instance, it is stated that tho 
majority of the vaccinations had been performed by a superannuated excise 
officer, and the only fatal case that occurred had been vaccinated by this 
man, and by him pronounced safe. 

This Committee say ^ the total number of deaths reported by all the 
gentlemen who have answered our questions, throughout nearly the whole of 
England, amount to very little above thirty. They say also, that they have 
the testimony of those who have been engaged in the practice of vaccination 
from its commencement down to the time of their report (1839), who have 
never met with an instance of this kind. One gentleman who began in 1802, 
and had vaccinated from six to seven thousand, had not met with more 
than ten or twelve failures, and not one death. Another who commenced in 
1806, under the immediate inspection of Dr. Jenner himself, and who con- 
tinued to practise it up to 1838, never saw a death from small pox after 
vaccination. Dr. Henry Jenner, the nephew of the distinguished Dr. J., 
met with the same result. Another who had vaccinated extensively and 
gratuitously tor twenty-four years, had not seen twenty cases of modified 
small pox, and not a death after vaccination. 

Mr. Ceely, of Aylesbury, reported that there were twenty-eight deaths by 
small pox last year in that place (1838), but not one occurred after vacci- 
nation. 

Another practitioner of vaccination for thirty-two years stited that, 
thout,Hi small pox had prevailed the previous winter (1838) to a great 
extent, and was vtry fatal, he had not seen in proportion more cases of that 
disease after vaccination than of small pox after small pox. 

One physician, who be^jfan to vaccinate in 1798, stated that "very few" 
cases of small pox had followed vaccination in his experience, and that in 
most of the instances of the khid whieh he had heard of, the vaccination 
had either been interrupted in its progress, or performed by a non-medical 
person. He f^ives one melancholy instiince in which a family had been 
" cut " by an itinerant quack, most of whom afterwards caught tlie small 
pox and died. He adds, that he had never seen a fatal case of small pox 
after vaccination, but liaJ seen five cases of small pox after small pox. 

Two physicians, father and son, could altogether enumerate about twenty- 
four persons in whom small pox had followed vaccination during the whole 
of their professional lives, and of these, they themselves only saw nine. 

Another, who had been settled in practice thirty-one years, had had two 




eases or Btnall pox nfter vHceinntion, both very niitd and modified ; and tind 
had tliree cusea of aecontkry nnall [iok, two after inoculation, OQC of wbkh

At tlio Roynl Military Asylum (England). 1406 children were adtoitted 
from 18in to 1837, and all were vftecinaied, whether prtvioualy vucciiialed or 
not : and among these, one Ciuc of small pox or varioloid eruption happened 
in 1826, During a pan of thia time, amallpoi had been Tery prevalent and 
fiiUl among Iho poor. 

Of onu hundred and fourteen coaea after reputed v«ccina Won in 1837,

Ihouaand fix hundred and forty-aix persona were vaccinated from IBM to 
1S33, and among these, only two dciitha by small pox occnrrvd, and one «f 
liie«e of a very doubtful nature. 

In tho Roynl Military Asylum at Chelsea, from August. 1803, to Augnit, 
1833, those reported lo hare had sronll pox before udmieaion were 3982 
(1887 boys, 645 girls); the nnmber reported to have been vaccinaled before 
admission was 30GO (3459 boys, G62 girls). Those who liad small pox 
after re|iuted small pox were -26 (Ifi boys and 11 girU). The casea of 
■moll |Kix after reputed vaccination were 2-1; 19 boys and S girls. The 
whole nnmbur vofcinated at tho asylum aubsequently to admission waa 
636; 46a boys and 108 giris. Of the whole, only two boys nnd one girl 
oangfat the small pox. Five deatiis occurred ; four boya and one giri. Of 
the«e five children, Ihrce hnd the disease after reputed small pox, nnd two 
had neitlier been vaccinated nor bod undei^one the amall pox before. In 
tbia instance, it will be aeen that not a single deaUi occurred after TBccioa- 
tion, while three out of the five fotal cases were after amall poi. 

Dr, Labntl, who, from the commencement, paid very great attention to 
the character of faccination, and watched it witli care, atalea that, from his 
obaervstion, "the reputed failures have almost invariably originated either 
from want of skill or inattention of pmctitionera, from inoculation having 
been performed by unprofesdonal persona, or the extreme inattention of 
perents and others in not showing children at the several stages of the 
■ffection." He adds that, during an extentive practioe of tliirty-six yean 
■nd upwards, be has not witnessed a nngle cose of death ft'om small pox 
after regular vaccination, and not more than Icn caaes in which tinuill pOX 
occorred in persons who previously had cow pox. 

In one of the largest institutions of Dublin (none not mentioned), tha 
average number of whose inmairji was between 3000 and 3000, np to Hie 
latter port of Horch, 1839, thirty-eight cases of small pox hod occurred, nnd 
but a single caae of that disease afl«r vaccinaliDn. and that in n child said 
to have been vaccinated two years before in Liverpool, but on whose arm 
there was no trace of cow pox. 

The Committee of the Prov. Med. and Surg. Assoclal. conclude their

remarks on the continued protective power of cow pox by saying, ** we hold 
it to be proved beyond all doubt, that the same laws which govern human 
small pox apply, * mutatis mutandis^ to cow small poxP They deny that 
the cow small pox, duly and efficiently communicated to man, loses its 
inj9uence by time. They remark tliat in the midst of such conflicting 
evidence, there is no other way than to recur to first principles, and inquire 
whether the lymph has been pure, and the development of the aflfection 
regular and complete, and the state of the patient such as to present no 
impediment to the regular course of the affection. A patient should never 
be considered safe, nor has vaccination been duly performed, unless all 
these things have been attended to, and it is doubtless to the neglect of 
sucli attention that many failures are to be attributed. They add, *^aU cases 
cf reputed vacciruiiioTi, unless they have passed under review of a competent 
judge^ who has untnessed the different stages of the affection, should be 
considered as ho vaccination at all." 

Mr. Thomas Hunt, of London, says, ^in a large medical practice in 
Hertfordshire, embracing the majority of the population of thirty square 
miles, only one case of small pox occurred in seven years — from 1812 to 
1819, and that not after vaccination. At that time, medical men only 
vaccinated." "Dr. Walker, who vaccinated with his own hands half a 
million of human beings, and pronounced them all secure for life, after 
being engaged in vaccinating for thirty years, saw but two cases of small 
pox after vaccination, and these, he says, were two lives saved ; for they 
only out of two hiTge families were vaccinated, and the rest all perished 
with the disease." (On Protective Power of Vjxccination — Prov. Med. and 
Surg. Jour., Sept 18, 1850.) 

^fr. Xewnliuni s^iys, '* instances of perfect security after vaccination may 
be multiplied indetlnitely : the instances of failure arc few in comparison with 
the numhers vaccinated : and the cases of death from really modified small 
pox, by j)revious elVective vaccination, are, u{)on the i^'ross scale, inappre- 
ciably few." (Prov. Mid. and Siinr. Jour., ^Uiy 1, 1850.) 

We have thus far confined ourselves to statistics furnished by English 
practitioners, for the purpose of a more fair compari.Non with those furnished 
by our author — but have reason to believe that those furnished by conti- 
nental practitioners, as well an those of our country, will atlbrd a corres- 
pondini: low state of mortality after vaccination. 

From a table })repnred by ^I. Villeueuve, Reporter of a Commission 
appointed by the Academy of Medicine at Paris, it appears that of 8G5 cases 
of confirmed small \)ox, in persons who had been at some previous j)eriod 
succosl'ully vaccinated, there were only ei^dit tlmt proved fatal — about 1 
in '15 or -KJ. (Anirr. Jaur. Mrd. Sci., July, 1841.) 

]\I. 13ous(pKt has collected the statistics of thirty-one epidemics in different 
part^ of France, from 18J() to 1811 inclusive, which he has presented in a 
tabular form, and from these we learn, that of G.OTl persons atUicked with 
variola after vaccination, only sixty-three died, or about one per cent.; 
while during the same series of years, of thirty-four cases of secondary 



▲FPENDIX. 369 

small pox, five proved fatal. (Nauveau TrailS de la Vaccine, Paris, 1848.) 
It mast be remembered that these results occurred during epidemic preva- 
lence, a condition necessary for the proper settlement of the question. The 
same author has also collected, with great industry, extended statistics 
on this subject from other countries, presenting evidence of the same 
general character, to which we must refer our reader, without transferring 
them to our pages. 

Dr. Luther V. Bell, of Derry (N. H.), states, as the result of his own 
experience, that no instance of death, when vaccination was performed prior 
to exposure, had occurred in more than two hundred cases of variolous 
disease attended by him, and a very large number of other cases he had 
witnessed. {Amer. Jour, Med ScLy May, 1836.) 

According to the Report of Drs. Mitchell and Bell, who had charge of 
the Small Pox H6spital in Philadelphia, forty-seven cases occurred there in 
1823-24, in persons who had been previously afiected by vaccination, and 
not one proved fatal. Eight cases occurred in persons previously affected 
with small pox, of whom four died. (Quoted by Dr. Chapman — Eruptive 
FeterSi p. 91.) 

A committee of the Philadelphia Medical Society, appointed to collect 
facts upon the subject of small pox, say, ^ We may, without the least want 
of candor, come to the conclusion, that only one death from small pox after 
vaccination has occurred in Philadelphia during the year 1827, amoii<r eighty 
thousand vaccinated persons, and during the prevalence of a most malignant 
and mortal small pox ; while several individuals have lost their lives by 
small pox, after they had already gone once through the disease." (Quoted 
by Dr. Morton — Notes on MackintosKs Practice of Medicine^ 4th Amer. 
Edit., p. 174.) 

We might multiply statements from still other soun*es of the same 
general character with tho«e already quoted, but will not enter into furtlier 
detail, as we feel that sufficient has been brought forward to console us 
with the belief that the rate of mortality by small pox after Viiccination, at 
least in countries at large, falls short of that shown by the statistics of the 
Small Pox Hospital of London to be true with regard to that iiiHiiiution — 
and we cannot but hope that the high rate of seven per cent, may be con- 
fined to limited sections of country, and perhaps to hospitals nlont', and thus 
depend upon circumstances more or less local in their chanicier. 

As these sheets were on the eve of going to press, we rect ived from Dr. 
Gregory the following table, giving the statistics of the London Small Pox 
Hospital for the ten years from 1841 to 1850 inclusive, which, as will bo 
seen, fully sustain the rate of mortality by small pox after vaccination in 
that institution, as already stated by him.

We feel that the propriety, if not the daty, of re-vaccinatioii is now m 
generaltf acknowled^ as perhaps to render it mineeegsary for na to 
adduce evidence in fiivor of the practice. But an the views of some on the 
■object may not be so fully established, and as others may feel interested in 
an examination of the evidence by vhieh it ia aupported, we have conduded 
to devote a short apace to it 

Some of the earliest, and at the same time moat conclUMve testimony in 
its favor, is famished by its reaulta in the Wirtemberg, Hanoverian, Bav*- 
riiin, and eapedaliy in the PmsBian armies. Our limits will not permit Dl

APPENDIX. 871 

and we can only transfer to our pages some of their most striking featores 
and items. 

Re-vaccination was first ^ commenced systematically in the Prussian 
armies in the year 1833, after having been practised in the Wirtemberg 
army and among smaller bodies of men for several years previously, and 
recommended by several leading practitioners, and has been continued in 
that and in several other armies, and also among large bodies of civilians, 
from that time to the present. The following are among the results : 

In Wirtemberg, but one case of variola occurred in five years among 
14,384 re- vaccinated soldiers, and three only among 26,864 re-vaccinated 
civilians. 

Not a single case of small pox occurred among those who had been 
re-vaccinated in the Prussian army in 1836, 1837, or 1839. But three 
deaths by this disease occurred in all the military hospitals of Prussia in 
1841, and of these, one was in a person not vaccinated on entering the 
army, because it had been done shortly before ; a second in a recruit who 
had not been re- vaccinated ; and the third in an officer, who had been 
re-vaccinated some years before, but without success. 

In 1834, two deaths are recorded of those who had been re- vaccinated 
with effect in the Prussian army, and one in 1843. In 1849, but one case 
was fatal, and this was in a recruit, vaccinated when a child, and who had 
not yet been re-vaccinated. 

During an epidemic of small pox in Copenhagen in 1828 to 1830, and 
also a very severe one in 1832, and another in 1835, not a single instance 
of variolous or varioloid disease was obsen^ed among any who had been 
re-vaccinated. 

In the Danish army, of those who were successfully re-vaccinated in 
1838, not one was attacked with small pox. 

In an epidemic of variola at Heidclburgh in 1843 and 1844, described by 
Dr. Hoefle, of all those attacked, not a single one had been previously 
re-vaccinated, while the vaccinations most successfully made did not protect 
from the most severe varioloid those older than ten years. 

M. Lombard stated, during a late discussion at the Belgian Academy of 
Medicine, that in the dreadful epidemic of variola which has just desolated 
Liege, none of those who underwent re-vaccination took the disease. 
{Brit and For. Med. Chir. Rer., Jan. 1851.) 

Steinbrenner, as the result of extensive investigation of the subject, says, 
** re-vaccination is the indispensable complement of the first vaccination, not 
that it is always necessary, as some pretend who admit the loss of its pro- 
tective power by time, but because it is necessary in very many cases, and 
because there is no other means of distinguishing such urgent cases from 
those in which re-vaccination is unnecessary." (Traitt sur la Vaccineyp. 
684.) He derives his arguments in favor of re-vaccination from its effects 
in the different European armies to which we have already alluded, as well 
as when performed by various individuals on a smaller scale, of which he 
presents a long array, and says that, in the absence of every other argument, 



these results are atrongty in its favor, beconw it ia impDunble that the pro- 
cess shuulil be BO often succesaral unless the saccess depended vpon k 
[««dl»poulioD which exposed the bdividrnds to taiiota. He also demotk 
otrnt^Mi the necessity of general re-vnctiiiBti«D by conudemliotis derived 
iVoiu tliu loo great frequency of raecinntions whieli fire not alt protective, or 
only iiD|K<rf(jet1y h«. 

H. Bouaquot sajs, sfler giving a long list of inilJUKes of protection by 
K-Tsccinntion without a failure, even in the midst of e^croics, a 1 
whicb. he say*, be oonld easily extend, " there has not been an epidea 
Whkh bus not proved, st tbe some time, tbo vinnea both of Tsecinatioii and 
of re-voccination." (iVout«au Tnnli de la Vaccine — Piiri:<i. IS48, p. 506-) 
He also nays (p. fiO 1 ), " tbe success of rc-voecination is at the same time 
cdect and the proof of the wants of the syBtem" — "when it sncceeds, it 
only proves that the protecliTO power of vacnnalion is dioiioi^ed, but it 
■ntapliei a nmedy for tbis diminution," 

The following are the conclnaions on this subject of the Committee o 
Vaccination, of the French Academy, as contained in tlieir report to that 
body, in Febniary, 1846- — 

1. Snuill pox ranily attncka those who have b«en vaecinoted before the 
•g« of t«l or twelve, from which age, sntil thirty or thir^-fire, they a: 
^Uible to Muall pox. 

ia the only known method of distingiu«fatDg those 
nt remfun protected, from tlioBe thai du Dot. 

t. The stweeaa of re-vMeiiuitioD is not » certain pioot that the penon n 
whom K succeeds was Iwble to contract small poz ; it merely eetablidiM • 
tolerably strong presumption that be was more or less liable to take it. 

4. In ordinary perioda, re -vaccination ahonld be practiaed after foarteen 
years, but sooner daring an epidemic. 

Among the eoDclnaions of a report on the subjeet of vaecinatioD, lately 
made by a Committee to the Belgian Academy of Medicine, are the 
following : — 

■* As the immunity conferred by vaccination is not indefinitely abaidnte, 
re-VBceinalion, at least for a great numlier of individnalt, is lalienaUj 
indicated. 

" Experience bas proved that a recent re-vaocination preserves from variolft 
and varioloid, and that, practised on a sufficient scsle, conjointly with v^xA- 
nation, it constitnlee a snre means of arresting the progresa of this maladj 
when it appears epidemically. 

" It succeeds best in proportion as it is most required, that is, the taore 
remote the period dnce the individual has bad varioia, or has been vacei- 
nated. 

"During the prevaleoca of an epidemic cJ variola or varioloid, it is 
pmdent to re-vaccinate all those whose first vaccination dates ten yean 
bock, and all those whose filat vaccinatJOD givea rise to any donbL" (Brit. 
and for. Med. Cfiir. Rev.,Jan. 1851— from Gat. Mid.) 

Tommaiiid was led by liia obeervations of it* resnlU during an epidemie

of varioU in Italy, to recomroond it to his fell ow-country men, and we might 
add iJie DumeB of many higlily diatingniahed of our proiesAion on both 
tides of the Atlantic, who concur fully in the imporUnce of the practice, 
and some who even think it eriminai to neglect it. 

We cannot but feel, therefore, in view of these faets, that the testimony 
in &var of re- vaccination is too strong to admit of its neglect. If no other 
argument could be adduced, the fact that it immediately arreits the course 
of epidemics when they appear, and that its fajthfnl performance has almost 
entirely banished small pox from somo armies in which it had formerly 
coratnitled great tavagos, would aeem conclusive in its fevor. 

It may perhaps be said that tlie results in the European armies to which 
we have referred speak against the manner in whicli primary vaccination 
was performed in these cases, and con bnrdlj, with justice, be advanced in 
proof of what would have occurred, bod the process been perfect in every 
respvct. But allowing this to be true, they may still be adduced as a 
warning of the danger to which our own population is at least partially 
exposed ; for it cannot but be true, that the process has been not no&e- 
quently performed among ue in sacb a way as to diminit^h, if not entirely 
destroy, its protective power. Hence, we need re- vaccinal ion as a lest of 
security, and as the only one within our reacL And when we con!<ider tbe 
almost perfect prolculion, thus far at least, afforded by ro-vaccinalion, and 
how trifling is the operation, we con surely hardly entertain for a moment 
the idea of resorting to variolous inocuhilion, either as a test, or fur addi- 
tional security against the failures of vaccination — an operation which is at 
least oc«a^unally fatal, which subjects those on whom it h> performed to 
Bome of the serious results which follow in the train of variola itself, and 
which cannot be practised without multiplying centres of contagion, and 
thns aiding the rovagea of the very enemy it ia intended to combaL 

It ia proper, however, to alate, that the value of this practice is doubted 
by some, and even ila propriety questioned. 

Occasional instances of an aitaek of varioloid after re-vacclnation doubtless 
do occur ; but lliey are so rare as to be thought worthy of record when a 
aingle one occurs. Bousquet gives a case in an infant M. Newnham also 
gives a case, after re-voccl nation by himself. (iVoii. Med. and Svrg. Jnun, 
Hay I, IBtiO.) Ue considers the practice as a test of the efficacy of Ihe 
first vaccination, and not a renewal of its bifloencc, which, he contends, 
con never take place. The occurrence of n regnlnr vaccine veu<.'1e after 
re-voccination he regards as a proof tliat the individual had not jtrerioasly 
been successfully vaccinated. 

It is true, as our author remarks, that a lulenied commission, nppoiuted 
for the purpose in Paris, reported against the practice of re-vaccination ; bat 
it is equully true that another commission (the one whose conclusions we 
have quoted), appointed for the same purpose, at a later date, reported in 
its favor. 

As to the ago at which its prxtice should be advised, that of about ten 
or twelve years is the one most generally recommended, advice founded a

EXPLANATION OF THE PLATES. 



PLATE I. 

The casual ano pox on the teaU and udder of a black and white milch cow» 

The disease is at its acm6 ; and tbo skin being fair, a slight areola is visible 
aroond some of the vesicles, many of which have a bluish central tint. It exhibits 
papulae, vesicles with central crusts, unacuminated and acuminated vesicles; 
imperfectly developed and also broken vesicles, both solitary and interfluent. 
The vesicles on the extremities of the teats are nearly of the color of the skin on 
which they are placed — a circumstance of itself sufficient to distinguish them from 
spurious or sub-epidermic vesicles. 

TLATE n. 

Casual vaccine vesicles on the thumb and finger of a boy who commenced 
milking on the 9th of October. On the 19th, he observed on his finger a red 
pimple of the size of a pin's head, and the next day, one on the thumb, very small. 
The engraving representfl the vesicles as they appeared on the 23d, four days after 
the first was observed, and three days after the second. 

On the finger, the vesicle was small and flat, with a slightly depressed centre, 
contaioing a minute crust. On the tliumb, the vesicle was also flat and broad, but 
visibly depressed towards the centre, where there appeared a transverse linear- 
shaped crust, corresponding, doubtless, with a fissure in the fold of the cuticle. 

PI^VTE ni. 

Casual vaccine vesicles on the hand and thumb on the eighth day afler the 
pimples were first observed (ninth day of papulation). 

On the side of the thumb was a flat vesicle, raised on a hard, red, tumid base. 
The vesicle was of a dirty white hue, with a slight central discoloration rather 
than depression, and a pale red areola extended around the vesicle, and beyond 
the last joint of tho thumb.
