THIS SECOND VOLUME

PREFACE
This little book does not pretend to be a complete
treatise on the local treatment of diseases of the skin ;
nor is there any attempt to cover all the ground relating
to local cutaneous therapy, the principal diseases mainly
being mentioned. But it is claimed that it gives practi-
cal suggestions in regard to many matters which are not
ordinarily found in text books, and which the experience
of the writer has showm to be of material service in the
daily management of this class of affections.
These four lectures were given to practicing physi-
cians at the New York Skin and Cancer Hospital in the
spring of 1906, at the close of the course of Clinical
Demonstrations of Diseases of the Skin, during the fall
and winter, and are printed in response to requests for
them. As was explained in regard to those given during
the preceding spring, " On the Relations of Diseases of
the Skin to Internal Disorders," it was found that dur-
ing the course of ordinary clinical lectures it was not
feasible to dwell on many points of importance relating
to the constitutional relations and treatment of this class
of maladies, so in regard to local therapeutics, there
were many items which could not be elaborated in the
hour devoted to clinical demonstration.
In these lectures, therefore, I sought to develop the
principles underlying local treatment, and then to illus-
VIH PREFACE
trate these by applying them to certain of the more
common diseases of the skin.
Like the former volume, this is essentially a personal
one, and very little reference is made to other workers
in the same field. This is, naturally, not from any dis-
regard of the views or practice of others, nor from undue
egotism, but is only conditioned by the exigencies of
the occasion. In the brief period of a lecture it is
impossible to enter into any discussion of various treat-
ments; moreover, I believed that my audience wished
to know what I had found effective and best under
various conditions, and what remedies and methods of
treatment had given the best results in private and
hospital practice. As in my lectures of last year, I
have endeavored to have my hearers see things as I see
them, and to profit by my personal experience in private
and public practice.
The knowledge of every one is composed of so many
different elements, and acquired in so many different
ways, that after a while it is impossible to differentiate
as to just where this or that suggestion or idea origi-
nated ; but as it has become part of the speaker's knowl-
edge or experience, and often has been modified, and as
it was desired simply to make matters as clear as possi-
ble, in a practical manner, most of the statements are
made as though they were wholly the result of personal
experience.
The number of the formulae given is not so very
large, and I believe that if all those practically used by
any skillful dermatologist were recorded, they would
not bv so numerous as might be imagined. As remarked
PEEFACE IX
in the lectures, the best way is not to have a great num-
ber of remedies, or to change from one to another,
influenced by the most recent statements or advertise-
ments, but to have relatively few medicaments and to
know well when and how to employ them.
Therefore, in these lectures I endeavored to make
plain what was desired to be accomplished, and to estab-
lish principles of local therapeutics, as well as to give
certain practical hints as to their employment. How
far I may have succeeded cannot be known until those
not very familiar with dermatological practice have put
them into active use. It is sincerely hoped that they
may find many of the suggestions given to be of practical
value. To aid in the practical utility of the little book
I have made a very full index, which will often refer to
the same disease mentioned under different topics.

GENTI.EMEN :
Last year I gave four lectures on "The Relation of
Diseases of the Skin to Internal Disorders," in ^Yhich
I tried to present as simply as possible the immense
importance of internal disorders in connection with
many. diseases of the skin; also to show why local treat-
ment alone did not yield the satisfactory results often
desired, and perhaps expected, from the strong state-
ments of those who advocated various applications.
I think that I demonstrated pretty clearly that the
truly successful dermatologist must be a thoroughly all-
1
2 PEINCIPLES AND APPLICATION OF LOCAL
round physician, and that he must exercise great
patience in investigating perseveringly the conditions
of those coming under his charge, and possess skill in
discovering and rectifying systemic errors which often
have the greatest influence on the skin and its diseases.
I also entered somewhat fully into matters of diet and
hygiene, and attempted to lay down some rules for the
same; and after drawing deductions from what had
been said, I endeavored to establish some principles in
regard to internal therapeutics.
Looking over these lectures as they have appeared in
print, I wish to say that I am daily more and more
convinced of the correctness and reasonableness of all
that I said and printed, and do not wish to retract one
iota, but only wished that I could have impressed the
matter more forcibly.
I will, however, remind you of a remark which I
made last year, in reference to the relative importance
of purely local measures, and a proper general treat-
ment, dietetic, hygienic, and medicinal. I said, that,
in a considerable proportion of instances, if I wore
compelled to choose between an exclusively local treat-
ment and one based solely on the facts and principles
which I had presented in those lectures, I should very
certainly choose the latter, as being most likely to con-
serve the best interests of the patient, and to secure the
best ultimate results in regard to many cases of diseases
of the skin.
But you will remember, however, that I also repeat-
edly stated, that all this presupposed the employment
of correct local treatment, without which there could
TREATMENT IN DISEASES OF THE SKIN 3
be no really successful dermatologieal practice; and I
expressed the hope that this year I might be able to
give you some special lectures upon local therapeutics;
which I shall now try to do.
It is much to do the right thing, but it is also a great
deal not to do the wrong thing locally, in diseases of the
skin. The reason why the oxide of zinc ointment,
popularized by the late Sir Erasmus Wilson of London,
has found such great acceptance with the profession, is
found, I think, in its bland character; so that, while
it often may not accomplish all that could be desired, it
has the advantage that it forms a mild and generally
unirritating application, which, like the Irishman's holy
water, "if it does you no good, it will do you no harm."
But I trust that you will see, before the course is over,
that, as in the case of the relation of diseases of the skin
to internal disorders, so, in the local treatment of these
affections, there are many conditions of prime impor-
tance to be considered: and you will, perhaps, better
understand why the oxide of zinc ointment is not an
universal panacea.
The same may be said iu regard to the many adver-
tised quack and semi-quack applications, which are so
impudently flaunted before the medical as well as the
general public, as "good for diseases of the skin." Xo
one remedy or combination of remedies can possibly
be of value in all forms of skin affections, nor even in
the same eruption in its various stages and in different
individuals. A certain amount of personal knowledge
and judgment is always necessary to determine the
exactly proper application for a diseased surface. And,
4 PEINCIPLES AND APPLICATION OF LOCAL
as will appear later, the method of making applications
and the mode of treating the affected part generally,
have a very great bearing on the success attained.
Before studying the principles of local therapeutics,
and trying to appreciate the why and the how of making
applications for the cure of diseased skin, it is necessary
that one should imderstand rightly the organ or part of
the body under treatment. I must, therefore, beg your
indulgence while I briefly recall to your attention
enough of the Anatomy and Physiology of the skin to
enable those of you not specifically familiar with derma-
tology to grasp the subject well.
I need not weary you with the details of its structure
and that of its appendages, which are found in text
books; but I must remind you, however, that the skin
is not simply a covering for the body, but that it is a
marvellous structure, wonderfully adapted for its pur-
pose, composed of many elements, and continually per-
forming a most important part in regulating the heat
of the body. An idea of the important and intimate
relations of the skin with the rest of the economy is
learned from the effects of extensive burns, which are
attended with profound shock, and often with ulceration
of the intestine, and with suppression of the urine, and
are frequently the cause of death.
xMthough the local treatment of diseases of the skin
has, of course, largely to do with its exterior surface,
in order to use local remedies intelligently and success-
fully it is essential to bear well in mind the anatomy of
the organ treated, and to some extent the histopathology
of its diseases. And T think that if this is done we will
TREATMENT IN DISEASES OF THE SKIN 5
understand why some of the remedies often very highly
lauded are not followed by better results.
First, it is well to bear in mind that in reality what
we call the skin consists mainly of the deeper, librous
portion, or true skin, which forms perhaps seven-
eighths of its structure, while the epidermis, upon
which we make our applications, is only a comparatively
thin covering of cells, which is relatively inert, and
impervious; and, moreover, that this epidermal cover-
ing is intended for the protection of more delicate struc-
tures beneath, and that by its very imperviousness it
serves to prevent the too great loss of heat from the body.
We all know that it is the epidermis which protects us
from syphilitic and other infection, which readily takes
place when it is abraded.
It is well to remember that the outer layers of the
epidermis are really dead matter, and are continually
being thro^^Tl off in health, being replaced by advancing
layers from beneath, which undergo cornification. Were
it not for the very many openings in the skin at the
orifices of its glands and the hairs, it is probable that
there would be very little absorption, and even less
effect from remedies applied externally than is generally
obtained.
While the external layers of the epidermis are prac-
tically without life, and can be scraped off without
causing sensation, the lower layers, especially the rete
!Malpighii, are supplied with terminal nerve filaments,
and, as all know, may be exquisitely sensitive, when-
ever the outer or scarf skin has been removed forcibly
or by disease.
6 PEIXCIPLES AND APPLICATION OF LOCAL
Pigmentation in the skin, which is found normally in
the darker races and on some regions of the body, and
pathologically in certain skin conditions, is located in
the deeper cells of the epidermis, in the rete mucosum,
just above the papilla of the corium. It is understood,
therefore, how difficult it is to remove pigmentary dis-
coloration of the skin, unless the composition of these
deep-lying cells can be affected and altered.
Coming now to the true skin, or corium, we find it
quite a different structure. Here we have to do with a
live, active tissue, composed of interlacing fibres, closely
felted together, making a compact, tough, yet very
elastic tissue, which forms the leather of commerce.
This is also a very complex structure, whose elements
it is well to bear in mind.
The outer portion of it, or papillary layer, is thro^vn
into innumerable prominences, between which the epi-
dermal cells of the rete Malpighii extend, and is very
important dermatologically, for it is from this that the
deeper, succulent cells of the rete ]\Ialpighii receive their
constant nutriment; and it is here that we find very
many of the pathological changes in various diseases of
the skin.
The blood supply of the skin is exceedingly abundant,
as may be judged from the fact that the finest needle
cannot be introduced without wounding some capillary.
A large share of cutaneous diseases are associated with
vascular derangement, and from the blood vessels, of
course, come the plastic or other materials of which
most skin lesions are formed. It can readily be seen,
therefore, that the cutaneous vascular system is one
TEEATMENT IN DISEASES OF THE SKIN 7
which must be reckoned with in the local or general
treatment of this class of diseases.
As yet we know comparatively little in regard to the
relation of the lymphatic systein to diseases of the skin,
but from what has been ascertained as to the very great
abundance of l^-mph channels and spaces in the skin
everywhere, they must be of importance in connection
with many cutaneous conditions. We all know how
readily syphilitic or other infection is taken from the
slightest abrasion, and how soon it is evidenced by par-
ticipation of the lymphatic glands.
The nerves of the skin play a very prominent part in
connection with many of its diseases, and are to be con-
sidered continually in their treatment ; their abundance
and universal distribution is shown by the pain caused
by the slightest prick of a needle, anywhere on the
surface.
We need not stop to consider the different nerve ter-
minations which have to do with various tactile and
other sensations in the skin, about which there is still
much diversity of opinion. But no one can fully grasp
the facts in regard to the immense supply of cutaneous
nerves, and realize the impressions which may be made
on them by various pathological changes in the skin,
without better appreciating the difficulties constantly
met wnth in giving relief by local treatment, to the
different sensations of itching, tickling, creeping, crawl-
ing, burning, or pain which may distress the patient.
The motor and vaso-motor nerves of the skin also play
an important part, the former in controlling the action of
the delicate muscles of the skin, especially those which
8 PRINCIPLES AND APPLICATION OF LOCAL
erect the hairs and facilitate the expulsion of the con-
tents of the sebaceous glands, and the latter which con-
trol the capillary circulation. The readiness with which
the skin flushes from nervous causes, as in blushing and
anger, and blanches, as from fright or from nausea,
and also the occurrence of sweating, unconnected with
heat or exercise, are all illustrations of vaso-motor nerve
action, which same action has much to do with many
diseases of the skin. It is readily understood, therefore,
why local treatment alone may at times prove very
inefficient in controlling certain eruptions.
But the glands of the skin are also very essential
elements in its structure, and may themselves be the
seat of special diseases, or they may also be affected in
several cutaneous affections. The sweat glands are
deeply seated, in the very lowest portion of the skin, or
even in the sub-cutaneous tissue, with long, corkscrew-
like excretory ducts ; the sebaceous glands are less deeply
situated, but still well within the body of the corium or
true skin. We all know acne to be a disease of the seba-
ceous glands, and are familiar with the plugged folli-
cles in comedo ; but few realize, however, that the latter
are due to imperfect action of the gland cells and want
of tone of the tissues, which must often depend upon
lowered vitality, while the deep inflammation of acne
nodules occurs quite independently of any apparent
external influence. One can thus readily see why purely
local treatment can never secure great or permanent
benefits in these conditions. The deeply seated sweat
glands are under nervous control, and while occasionally
excessive perspiration will seem to be helped by local
TREATMENT IN DISEASES OF THE SKIN 9
measures, other than local treatment will be required
to remove the real difficulty.
The hair and nails are also important anatomical ele-
ments of the skin to understand, and yet very few seem
to rightly appreciate the kno\vn facts concerning them ;
some of which I will try to present as briefly as possible :
The relations of the hair and its follicles to the integu-
ment can be best understood by imagining the lower or
fibrous portion of the skin to be soft and plastic, and
the upper or epidermic layers to be pushed down into
it, without breaking, around a penetrating hair; the
sheaths of the hair are thus seen to be cellular, and to a
certain extent correspond to the layers of the epidermis.
We need not dwell here on the minute anatomy of the
different hair sheaths which have been described, the
practical point to be remembered is that they are cellu-
lar, like the epidermis, reaching down into and forming
the lining of a pocket in the fibrous structure of the
corium : this is of great importance in reference to the
vegetable parasitic diseases, as the fungus penetrates
deeply and lives on epithelial matter, including that of
the hair and its follicle. It is well also to remember
that there is more or less of a constriction of the hair
follicle, just below the line of the papillary layer of the
corium, and while the parasite extends as it grows, even
to the bottom of the follicle, remedies will not penetrate
much beyond this constricted point. Even when iodine
is applied to the scalp for some time, and the hairs
extracted, they will be found to be stained only part of
their entire length, while the fungus will be found far
below the line of the stain. Hence epilation is necessary
10 PEINCIPLES AND APPLICATION OF LOCAL
in order that a remedy mav have a chance to enter the
follicle more deeply, so that the newly-formed hair may
not be attacked.
At the bottom of the cell-lined hair follicle, which in
the case of the larger hairs, as on the scalp and bearded
face, extends through the extreme thickness of the skin,
the fibrous elements of the corium rise and form what is
known as the hair papilla, which is embraced by the
lower portion of the hair: this contains blood vessels
and affords nourishment to the hair. The hair itself
is composed, like the epidermis, of cells, and is a pro-
duction of the root sheath proper, at the lowest portion
of the follicle. When the healthy hair is pulled out, or
falls naturally, a new one begins to form around the
papilla, and the hair may thus be reproduced indefi-
nitely, as is seen when superfluous hairs on the face are
extracted again and again, only to grow larger. These
can be permanently removed only by some method
which will destroy the papilla and hair follicle in its
deeper portion, as is done by electrolysis. Knowing
the anatomy of the hair and its follicle, one can readily
understand why the advertised depilatories are utterly
worthless ; for it has been seen that while the hairs are
in place, remedies applied externally cannot possibly
penetrate to the depth of the follicle and so cannot
reach and destroy the tissues from which they grow. It
can also be appreciated why the many so-called hair
tonics cannot produce the wonderful effects often
claimed for them.
The nails, like the hair, are also only another altered
form of the epidermal layer of the skin ; the root is that
TEEATMENT IN DISEASES OF THE SKIN 11
embedded portion t(nviird the trunk, from which the
nail grows; and the body of the nail corresponds to the
section of the hair within the follicle, although it is
attached only on one side to the matrix or nail bed; the
free end of the nail, generally kept cut short, represents
the free portion of the hair. Affections of the nails are
often peculiarly rebellious to treatment, and it can
readily be seen that local remedies would have great
difficulty in penetrating and affecting such a structure.
While the root proper remains intact, however, the nail
may with proper treatment be restored, however far
the nail body may have been destroyed by disease.
The physiology of the skin is important to be remem-
bered in connection with dermatological practice. As a
vast excretory organ, with an estimated two million
sweat glands, it gives off as insensible perspiration,
under ordinary circumstances, between one and three
pints of fluid daily, almost as much as the kidneys, and
more than the lungs ; while under unusual conditions
the amount may be enormously increased. When this
is completely checked, as by varnishing the whole body,
the animal dies ; but the application of grease does not
act so injuriously; as is seen continually in this hospi-
tal, when patients are completely enveloped in ointments
for various diseased conditions.
The skin is often found to be dry, hard, and perform-
ing its functions badly. Much benefit can then be
obtained by proper local measures, such as appropriate
medicated or other baths, which will be more fully con-
sidered later, and by the judicious use of lubricating
ointments. Although, as was stated, the epidermis itself
12 PEINCIPLES AND APPLICATION OF LOCAL
is more or less impenetrable, external applications can
often enter the system through its pores, as is seen in
the case of salivation by mercurial inunctions and baths ;
iodide of potassium can also be made to appear in the
urine after its thorough application to the skin, in oint-
ment, and other remedies, such as quinine, belladonna,
tobacco, etc., can also be made to enter the body in the
same manner; indeed, one must sometimes be careful
in using belladonna or tobacco externally, for this rea-
son, and harm has come from the too free use of hydro-
cyanic acid locally, to relieve itching.
Remembering then the anatomy and physiology of
the skin, and the necessary limitations as to the results
which may be obtained by local treatment, some of
which have been suggested, let us consider, (1) The
aims to be accomplished; (2) The principles which are
involved; and (3) The effects to be expected from local
therapeutics.
I. The Aims to be Accomplished by Local Treatment.
Naturally every diseased condition of the skin will not
require the same local treatment, and, as far as possi-
ble, there should always be a definite idea of the aim to
be accomplished by the proposed application.
First it is to be remarked that, although a correct
diagnosis is of prime importance in dealing with dis-
eases of the skin, eruptions are not always necessarily
to be treated alone according to the name given to them ;
for it quite often happens that those of quite different
name, and perhaps somewhat different nature, will be
greatly benefited by the same local treatment, at some
stage in their progress: and one continually finds that
TEEATMEXT IN DISEASES OF THE SKIN 13
the same eruption will require entirely different treat-
ment at diflFerent periods. So then we must be guided
by something more than simply the diagnosis given to
a cutaneous affection, although undoubtedly a correct
diagnosis must be the fundamental fact around which
local and other treatment centers.
Proper local treatment is undoubtedly called for,
and is of decided advantage, in the majority of instances
of cutaneous affections, and promotes the restoration to
health of a diseased organ, which cannot perform its
functions rightly, and cannot successfully resist the
various external influences to which it is subjected.
It is also often necessary in order to give relief to symp-
toms such as itching, which may be very distressing.
Moreover, if adequate local treatment is not directed, the
part will be wrongly treated by the patient, who will
endeavor to make some application.
It is well, therefore, to consider the exact condition
of the part affected, and what is sought to be accom-
plished. Thus, whether the application is to be protec-
tive, soothing, emollient, astringent, anti-pruritic, anti-
parasitic, absorbent, stimulant, or caustic, will call for
very different remedies and often very different methods
of application, as will be sho\\Ti later. And it will
often require considerable thought and care, as also
some knowledge of the action of drugs, in order to
determine these matters properly.
From long observation I am convinced, gentlemen,
that many members of the medical profession do not
put sufficient thought and care into the treatment of
diseases of the skin, but are too apt to take up with this
14 PRINCIPLES AND APPLICATION OF LOCAL
or that local remedy, either one mentioned by some
authority or one offered by an advertising drug firm,
and when good results are not obtained they blame the
remedy or the obstinate nature of "skin diseases" (as
they class them all together). Too many are apt to
regard the field of cutaneous affections as a terra incog-
nita, which it is hopeless to explore and useless to try
to conquer.
While all must acknowledge that this branch of medi-
cine is not an easy one to compass, in all the intricacies
which have too often been needlessly thrown around it,
I assert that, wuth a reasonable amount of study and
thought, applied to individual cases, the general physi-
cian can accomplish very much more than is generally
thought or effected.
To return to the subject as to the aim or purpose
sought to be accomplished by the local treatment which
shall be instituted.
The errors which are constantly made in local thera-
peutics are generally in two directions: too strong reme-
dies are applied to irritated conditions of the skin, and
too weak applications to those requiring more decided
therapeutic effect ; exactly how to decide in every case
is, of course, a matter of knowledge and judgment,
which are acquired by observation, study and thought.
It is well to bear in mind what was said in regard to
the nerve supply and sensitiveness of the skin, when
the epidermal coat is disorganized or removed, for I
think that far more errors are made in the direction of
irritating applications than in that of too weak treat-
ment for more chronic conditions. It is better to err
TEEATMENT IN DISEASES OF THE SKIN 15
on the safe side, and it is undoubtedly for this reason
that so many prescribe oxide of zinc ointment, which,
if properly made, seldom proves irritating.
It may be remarked incidentally, that it is better to
have relatively few remedies or combinations, which
one shall learn to use well in different conditions, rather
than to have a great number, or to take up this or that
suggestion of others, and continually change. A good
workman does better work with his few tools, of which
he understands the use, than a poor workman supplied
with any number of tools of which he knows little. We
shall see later that the mode of using many applications
to the skin has very much to do with their efficacy; I
have often seen a remedy act inefficiently, as previously
employed, whereas the same article gave good results
when correctly applied. In the last lecture I shall hope
to make practical application of the principles and ideas
of local treatment to many of the diseases which we
have been observing this winter, and to give specific
directions, which I trust may be of value.
2. Principles Involved in the Local Treatment of Dis-
eases of the Skin. The skin being a delicate, sensitive,
living organ, with recuperative powers, intelligent local
treatment should be based on certain principles, having
relation to the structure of the skin and the manner in
which it is affected by disease. While many lesions of
the skin are largely the effect of external agencies, and
while the skin has a certain power of recuperation, it is
a recognized fact that many, if not most, of the cutane-
ous affections have a great pertinacity, and it may
almost be said that they have no tendency to spontaneous
16 PEINCIPLES AND APPLICATION OF LOCAL
recovery, and are prone to persist until removed by
treatment, local or general. In this the skin differs
from almost all other portions of the body, largely
because of its exposed location and its constant subjec-
tion to external irritants — for, even air and water often
prove to be such, perhaps largely because of their oxi-
dizing powers and microbic contents.
In considering local applications, therefore, we find
that their use is in reality based on certain principles,
whether recognized or not : some of these may be briefly
stated.
1. Protecting raw surfaces, or those with diseased
epidermal covering.
2. Allaying cutaneous congestion.
3. Soothing irritated nerve elements.
4. Neutralizing the effect of the micro-organisms
always present on the skin.
5. Stimulating sluggish vascular or hanphatic cir-
culation.
6. Producing absorption of effused products.
7. Exterminating grosser animal or vegetable para-
sites.
8. Destroying or altering new growths.
9. Minor or other surgical interference.
It would be quite impossible in the time at our dis-
posal to elaborate all the features pertaining to each of
these principles, but it is w^ell to consider the list, or the
thoughts expressed in it, when prescribing a local appli-
cation for a diseased surface ; for, from what has pre-
ceded and will follow, it will be abundantly recognized
that there is no one remedy, or combination of remedies,
TBEATMENT IN DISEASES OF THE SKIN 17
which can be "good for diseases of the skin," however
much the quack or semi-quack advertisements may say.
We may now consider briefly, in a general way, the
ap])lication of these principles to local dermatological
therapeutics; the special remedies and combinations,
with their applications to particular skin lesions, will
be indicated in subsequent lectures.
The conditions involving the first four principles are
generally found associated in most acute cutaneous dis-
eases, and the local application made is intended to
meet one or more of these in a satisfactory manner.
In affording protection the aim should be to imitate
nature as far as possible. Now w^e find that when there
is a raw surface, nature endeavors, by a more or less
thick coating, which we call a scale, crust, or scab, to
protect the exposed and delicate tissues beneath ; which
covering, if undisturbed, may quite suffice until the sub-
jacent structures have recovered health. This is seen
after a superficial abrasion or scratch, in a healthy per-
son. I may remind you how a blister raised artificially \
heals quickly and perfectly, if the epidermal covering j
is left intact, after the serum has been let out : and that '
in burns, and eruptions presenting bullae, it is often far
better simply to puncture them at the level of the skin,
and to leave the natural covering, rather than to remove]
it and attempt to substitute an artificial one.
It follows, therefore, that, First, all applications
should be bland and unirritating, and with a tendency
to promote healing beneath, and. Second, they should
not be disturbed oftener than is necessary for cleanliness
or good adjustment. We are learning from surgery;
18 PEINCIPLES AND APPLICATION OF LOCAL
for here the first dressing, even after a severe operation,
may be left in situ for very many days, and on removal
the wound is found to be quite healed.
Unfortunately, however, in treating diseases of the
skin the matter of the local dressing is not so simple, and
there are other elements to consider which often inter-
fere greatly with the success of local treatment. Thus,
owing to the location of the eruption it is often impossi-
ble, or at least infeasible, to make a fixed dressing,
beneath which the diseased surface shall return to
health. Then, there are often internal conditions, which
cannot be discussed here, which continually tend to keep
up the cutaneous congestion : furthermore, we have to
contend with the nerve elements, irritated deeply in the
skin, which external applications too often fail to reach
and soothe; also the dressing may be torn off, and the
surface further irritated by scratching. And finally we
have to reckon with the micro-organisms, always present
in great variety and abundance on the skin, which
become active as soon as they find the proper pabulum
afforded by the cutaneous congestion and exudation.
In regard to the latter point, it is to be remembered
that in the perfect surgical dressing referred to, com-
plete asepsis has been secured by relatively severe treat-
ment to the skin, which could not be practiced in acutely
inflamed conditions.
We thus see some of the reasons why local measures
do not always yield the satisfactory results desired, and
learn seme of the elements which have to be regarded
and provided against in seeking benefits from local
treatment in some diseases of the skin. Later we shall
TEEATMENT IN DISEASES OF THE SKIN 19
see more particularly how some of these can be com-
bated more or less successfully, in connection, of course,
with proper internal, dietary, hygienic, and medicinal
treatment. A few general remarks may be made here,
which may not find place elsewhere.
We have seen that surgical experience shows that
wounds heal, under proper conditions, when left undis-
turbed. It should be the aim to leave acutely inflamed
conditions of the skin in as quiescent a state as possible,
provided, of course, that healing is progressing well:
when there is much exudation, and especially if pus is
forming, this cannot be done. From long experience I
am convinced that much harm is done by the very fre-
quent changing of dressings, and especially by the prac-
tice, so common, of washing the diseased part and trying
to "keep it clean" ; time and again I have had to stop
this practice.
Scratching is undoubtedly the cause of a very consid-
erable proportion of the lesions seen on the skin in many
eruptions attended with itching. This must be pre-
vented, as far as possible, by wnll power, and, in the
case of younger patients, by mechanical restraint, aided
of course, by proper anti-pruritic remedies.
But the latter I have often seen dreadfully abused.
One constantly observes cases in which, in the effort to
secure relief from pruritus, stronger and stronger appli-
cations have been prescribed, until the parts have been
brought to a lamentable state of inflammation, with only
an increase in the itching and pain.
It is well to recognize the fact that in many cases it
is quite impossible to check deep-seated itching promptly
20 PEINCIPLES AND APPLICATION OF LOCAL
by local measures alone ; but it is also a fact that it can
commonly be checked by the judicious employment of
all known means combined. For there must be a cause,
and medical acumen can and should, with efficient
thought and patience, reach the difficulty and overcome
the cause, more often than is generally supposed.
Returning again to our illustration from the practice
of surgery, you will remember that the surprising re-
sults of modern days are attained by perfect asepsis:
you will, however, remember that we found this to be
well-nigh impossible in the case of most diseases of
the skin.
But it will be noticed that a large share of the appli-
cations used for diseases of the skin contain remedies
which are of a more or less antiseptic nature, and it is
to this feature that we must ascribe a measure of the
benefit accruing from them. The micro-organisms in-
fecting the skin have a relatively low grade of vitality,
and as a rule are rather saprophytic, living on dead
tissue, than really parasitic; and it may be observed
that the various alkaline constituents so often employed,
tend to render the soil less suitable for their develop-
ment. This, therefore, is a point to be considered in
compounding applications for the skin, but care should
be taken not to use antiseptic remedies of such a strength
as shall irritate delicate tissues, while endeavoring to
neutralize the effect of the micro-organisms constantly
present on the skin.
Thus far I have been speaking of acute eruptions,
and the danger of over-stimulating a sensitive surface.
But in a not inconsiderable proportion of the diseased
TEEATMENT IN DISEASES OF THE SKIN 21
conditions of the skin there is need of just this stimulant
action, as will be seen later: and in this class as well,
judgment will be required to carry it far enough and
not too far. This relates to the next four principles
mentioned in the list. Here mild remedies are of little
avail, and 3'et they may sometimes be required to over-
come excessive stimulation: for it is often necessary to
have a complete reaction after the employment of local
stimulants.
It was seen in our remarks concerning the anatomy
of the skin that the blood vessels and lymphatics play
an important part in the production of many cutaneous
diseases, ^^^lile we know relatively little in regard to
the causes of the changes in the blood vessels and I^tu-
phatics, and not much regarding the laws governing
their action, we do know that capillary and lymphatic
dilatation are constantly found in connection with many
of the more chronic skin lesions, and remedies looking
toward the stimulation of a healthy action in them are
certainly of benefit. Also in many of the more chronic
skin affections there are observed histologically great
hyperplasia of the rete, as well as effusion of serum and
great cell infiltration of the corium, which largely com-
pose the skin lesions; and remedies inducing absorp-
tion of these play an important part in local thera-
peutics.
In exterminating the grosser animal and vegetable
parasites of the skin the applications employed are all
of a more or less stimulating or irritating character, and
care has often to be exercised not to over-excite the living-
tissue. The same is somewhat true in regard to reme-
(
22 PRINCIPLES AND APPLICATION OF LOCAL
dies used for the destruction or altering of new growths
in the skin.
We see, therefore, that there are many lines, of quite
different character, along which local treatment must
proceed, and each must be determined and followed out
with care in order to secure the best results — and we
see yet more strongly than ever how impossible it is
that any one remedy, or combination of remedies, should
be "good for diseases of the skin," as the false adver-
tisements say.
3. Effects to be Expected from Local Treatment.
When water is put on fire we expect it to go out, if the
water is used in sufficient quantities and in the right
manner. But, unfortunately, as all know, the human
frame does not always respond to remedies in just the
manner expected, and this is especially true in regard
to the skin : disappointments are only too common, unless
carefully guarded against.
But these are not infrequently the result of want of
knowledge or experience. Sometimes it is the fault of
the patient, who docs not follow instructions perfectly,
sometimes that of the physician, who does not impress
them clearly or insist on them definitely. For, as
remarked before, patients are, as a rule, utterly ignorant
of these matters, and are frequently called on to use
remedies for the first time. Explicit instructions
should, therefore, be given, just how to use local appli-
cations, and statements made as to how tlioy are to act,
and what may be expected of them. This, of course,
is not always easy to do, but if a physician has a clear
idea as to what he washes to accomplish, in accordance
TKEATMENT IN DISEASES OF THE SKIN 23
with what has already been said, the task is less difficult.
Accurate prognosis is always a difficult task.
In a later lecture I will endeavor to give some prac-
tical suggestions in regard to the modes of making appli-
cations and dressings to diseased surfaces, and as to
removing the same, and in regard to the treatment gen-
erally of affected skin. I may here give a few indica-
tions as to what I mean by the effects to be expected
from local treatment.
First. Patients should be made very clearly to under-
stand that local treatment can be but local in its effects,
and as very many cutaneous diseases are not purely
local affairs, but have internal or constitutional relations,
therefore, for their perfect removal, other than local
treatment is necessary. This is constantly seen in
eczema, acne, urticaria, and many other affections, and
of course in syphilis, etc. Patients are very prone, after
a little while, to neglect everything but local treatment.
Second. That, with some exceptions, immediate and
perfectly satisfactory effects do not necessarily always
follow the use even of the best possible treatment. An
illustration of this is found in herpes zoster: here the
best local measures cannot wholly arrest the eruption;
but, on the other hand, they are of the greatest value in
giving relief to the burning and pain, and in carrying
through the eruption, which is self-limited, to its best
termination.
Third. When applications which are intended to be
cooling, sedative, and soothing, prove to be the reverse,
they should not be persisted in, for sensation is a very
sure indication of the progress, for better or worse, of
24 PKINCIPLES AND APPLICATION OF LOCAL
very many conditions of the skin. Thus, in infantile
eczema, any apj^lication which irritates the child, and
causes it to cry long, will pretty certainly prove harmful
to the eruption, instead of beneficial.
Fourth. On the contrary, in certain conditions the
local application is calculated to cause greater or less
discomfort, for a while at least, and if this is well
understood the desired results will be more likely to
follow. Thus, in the treatment of a severe case of
scabies, there is often considerable burning and pain,
certainly if there are any raw places, following the very
thorough rubbing in of the appropriate ointment : in
some cases of ring\vorm of the scalp it is necessary to
rub in the ointment, with a stiff stencil brush, even until
the child can stand it no longer: the pain following the
application of Marsden's paste for epithelioma is often
very severe indeed, lasting for some hours.
Time fails to give you many practical suggestions
whicli occur to me along these lines, and I must leave
them to your own intelligence and judgment. Suffice
it to say that while there is often much knack in deter-
mining just the right application, and in knowing what
may reasonably be expected of it, this can be accom-
plished much more often than is commonly supposed,
if sufficient care and thought are given, such as are
applied to disease of other organs than the skin. Here
let me again urge you not to try this or that treatment
recommended often by those of little experience, but to
use relatively few remedies and to become well ac-
quainted with them, so that you nuiy be better able to
know about what to expect from their employment.
TEEATMENT IN DISEASES OF THE SKIN 25
In the next lecture I shall attempt to classify many
of the remedies used externally in treating diseases of
the skin, and present desirable combinations of them.
In later lectures I shall hope to make satisfactory appli-
cations of the principles and demonstrate some of the
methods which have been discussed as they relate to
particular diseases of the skin.

Gentlemen :
In the last lecture I endeavored to give such a glance
at the anatomy and physiology of the skin as would
enable us to understand the rationale of the local treat-
ment of diseases of the skin. I also tried to lay down
some of the principles which should govern the relation
of external remedies to disease, and explained the aims
to be kept in view in approaching a case of disease of
the skin, and the effects to be expected from external
treatment.
I hope that I made it plain why we could not always
obtain the ends we desired by means of local applica-
tions, and, referring to my lectures of last year, I em-
phasized the necessity of complete treatment, by means
of internal, dietary, hygienic, and medicinal measures,
combined with proper local treatment, in order to secure
satisfactory results in many cutaneous disorders.
Bearing all this in mind, I will now try to make
practical application of the facts presented and the
principles laid do\\Ti. We will consider the subjects
under, (1) Ingredients and forms of local applications;
26
TREATMENT IX DISEASES OF THE SKIN €7
(2) Mode of making and removing local applications;
and (3) General treatment of diseased surfaces.
I. Ingredients and Forms of Local Applications. The
actual number of ingredients at times recommended in
connection with the external treatment of diseases of
the skin is quite large, and may seem somewhat confus-
ing to those unaccustomed to dermatological practice.
I shall not attempt to enumerate them all, but shall
present mainly those which are in most common use,
and those which I prescribe and believe to be of the
greatest value ; many of them you have seen advanta-
geously employed in the clinic during the past winter.
The character of external applications required was
seen in the last lecture to vary very greatly and was
briefly mentioned as coming under the following heads :
1, Protective ; 2, Soothing ; 3, Astringent ; 4, Anti-
pruritic; 5, Emollient; 6, Stimulant; 7, Absorbent;
8, Anti-parasitic; 9, Destructive.
We will consider the ingredients and forms of local
applications with reference to the above classification.
1. Protective Applications. In acute skin affections
the purpose of protection must always be kept in view ;
often much harm comes, even with the best applications,
from not having the diseased surface properly protected
against external influences. On the other hand, much
harm can be done by too great outer dressings, heating
the parts, when a cooling effect is desired.
A good illustration of what is intended by the above
is found in connection with herpes zoster. Here the
surface is exquisitely sensitive, and when not properly
cared for the friction of the ordinary clothing is in-
28 PEINCIPLES AND APPLICATION OF LOCAL
tensely irritating. But it does not do to apply plasters
or even ointments, for they lead to softening of the
epidermal covering of the blisters and often even pro-
duce an ulceration, which may be very slow to heal. A
most simple and effectual mode of treatment which I
have employed for years is to envelop the part firmly
with a single thickness of strong muslin, beneath which,
both on the affected skin and on the inner surface of the
muslin, there is dusted very freely a powder, composed
about as follows :
1. I^ Morphiae acetatis gr iii
Pulv. acidi saliyl 3i
Zinci oxidi 3iv
Pulv. amyli 5i
v\. ft. Pulv.
If this powder is thickly applied and the cloth closely
fitted, even sewing it on, it affords the greatest relief,
and may be left in place even some days, or readjusted
as required, and the vesicles dry up without breaking.
Such a dressing, of course, would not be suitable where
there was a raw surface.
Various ingredients may be used in dusting powders,
such as lycopodium, carbonate of magnesia, stearate of
zinc, etc., and pure buckwheat flour often forms a most
comfortable dressing, especially in acute ervthemato-
papular eczema; I have often had a hand or an arm
put in a muslin bag, in which was placed a handful of
buckwheat, which, as the part was moved, applied itself
very pleasantly and coolingly to the surface.
Many of the ointments to be mentioned, when prop-
TEEATMENT IN DISEASES OF THE SKIN 29
erly applied, afford much of their benefit by the protec-
tion given to the altered epidermis, allowing it time for
regrowth and cornification.
In many cases of chronic eczema the skin is con-
tinually irritated by outside influences, and proper
protection is a large element in its cure, and in many
cutaneous affections this feature proves an important
element in successful treatment.
2. Soothing Applications. In our glance at the anat-
omy of the skin we found that it was an extremely
sensitive structure, full of capillaries, and that the
nerves and blood vessels played a great part in cutane-
ous disorders. Consequently remedies of a soothing
character are constantly needed in acute eruptions.
Powders I have already spoken of, but they have rela-
tively little scope, and applications are made mainly
in the form of lotions and ointments. Poultices are
very rarely serviceable, and even in boils and carbuncles
they have been replaced by better measures. About the
only use I ever make of them is in the treatment of
epithelioma, after the application of Marsden's arsen-
ical paste, where, renewed every two hours, they secure
the complete sloughing out of the mass, and are kept
applied until all is perfectly healed.
Lotions are of very great value in soothing many
acute conditions of the skin. Lead and opium wash, so
commonly used of old, is now relatively seldom em-
ployed, but may occasionally be of value where there
is burning pain. Carron oil is still of value in burns,
although an ichthyol ointment often affords the most
relief.

Some skins do not bear glycerine well (although this
idiosyncrasy is often over-estimated), and gelanthum,
tragacanth, quince mucilage, or other demulcent can
be employed. Sometimes a more drying lotion, such as
the following, acts better :

n\. ft. Lotio.
A little carbolic acid can be added to this lotion, when
more anti-pruritic action is required, and the solid in-
gredients can be increased in both lotions when a more
abundant protective coat is desired.
Ointments are constantly used for soothing effects on
the s^vin, but there are several things to be remembered
about them which may greatly affect the results. First,
that there are certain skins which do not bear greasy
TREATMENT IN DISEASES OF THE SKIN 81
applications well ; second, that it often makes the great-
est difference in regard to the base or body employed in
the ointment, as well as its mineral or other ingredients ;
third, that not very infrequently an ointment will be
rancid, either from carelessness of the druggist, or by
being kept too long, and so may prove intensely irri-
tating; and, fourth, that the mode of application of
dressings to diseased surfaces, and the method of their
removal, influence the results obtained from the use of
ointments, often to a very great degree.
The latter point will be considered fully later on ; a
word may be said here in regard to the composition of
the ointment base.
Lard is the common base of very many of the oint-
ments of the Dispensatory, and to prevent rancidity it is
commonly treated with about two per cent, of benzoin,
or originally the tincture of benzoin was added. This
latter may prove irritating to the skin, and sometimes
lard is imperfectly benzoinated, and will not keep.
Wax and oils also often enter as ingredients, which
may likewise tend to rancidity ; the petroleum products,
paraffin, vaseline, albolene, etc., are also used considera-
bly as bases. But it must be remembered that vaseline
is not acceptable to every skin ; not at all infrequently
an ointment made up with it will prove irritating, w^hen
the same ingredients combined with another base will
be satisfactory.
Vaseline and abolene are often of value when it is
desired to have only a lubricant effect, or a soft oint-
ment to penetrate, as in the hairy scalp, but as a pro-
tective dressing they do not generally answer, unless
3£ PEINCIPLES AND APPLICATION OF LOCAL
materially stiffened with powder, as in Lassar's paste,
or with wax, paraffin, or lanolin.
Lanolin is seldom suitable as a base alone. At one
time it was thought that it would be valuable, as pro-
moting absorption, when this was desired, but experi-
ments have shown that it is far inferior to vaseline in
this direction. Glycerite of starch often serves excel-
lently as an excipient in irritable conditions, but with
some skins glycerine proves irritating.
Perhaps the most serviceable base for most ointments,
and the one which I much prefer, is cold cream, or the
unguentum aquae rosae of the Pharmacopoeia: but care
must be exercised that it is well made and fresh, as it
is liable to become rancid, and the water in it to evapo-
rate. A little carbolic acid, one or two per cent,, will
preserve it for a considerable length of time. If the
odor of the rose water is objected to, this can be omitted,
but the same quantity of distilled water should be rubbed
into the ointment.
A word in regard to diachylon ointment, so commonly
associated with the name of Professor Hebra, of Vienna,
and which you have often seen used in the clinic. As
directed now to be made, in the Dispensatory, by melt-
ing together equal parts of lead plaster and olive oil,
it is not as serviceable as that made after Hebra's orig-
inal formula, for all of the oil is not decomposed in the
modern process, Hebra advised that the ointment be
made direct from the litharge, olive oil, and water, the
two latter in very much larger quantities, and the water
double that of the oil, all boiled together, with constant
stirring, and the litharge sifted in, the whole being
TREATMENT IN DISEASES OF THE SKIN 33
Stirred well, until a good, soft ointment is made. I al-
ways insist that what is used in the Hospital and in my
private practice be made in this manner, after the fol-
lowing formula :
5. I^ Plumbi oxidi 5iii4- 3vi
Olei oli varum optimi. . 3xv
Olei lavandulse 3ii
Aquse qs
n\. Add the oil to two pounds of water, and heat with
constant stirring; the litharge is to be slowly sifted in, while it is
well stirred, fresh water being added as required until a soft oint-
ment results. The ointment to be stirred till cold and the lavender
then added.
There are relatively few mineral or other substances
used in ointments which are of a soothing nature, and
of these oxide of zinc undoubtedly stands first, and is
used in many combinations. But I rarely use zinc oint-
ment of the official strength, and never order simply the
ointment of the Pharmacopoeia ; I always direct it to
be freshly made, with cold cream, 3ss ad §i, generally
with one or two per cent, of carbolic acid added. Pre-
pared calamine often forms a valuable addition, as in
the following formula :
6. I^ Acidi carbolic! gr v-x

TT|^. ft. Unguentum.
Sub-nitrate of bismuth is also valuable, and some-
times suits when zinc fails; it is used in the same
strength. Boric acid, if very finely powdered, is also
34 PEINCIPLES AXD APPLICATION OF LOCAL
satisfactory, and may be combined with camphor advan-
tageously, as follows :
7. I^ Pulv. camphorae 3ss-3i

3. Astringent Applications. The remedies already
mentioned are all more or less astringent, but in less
inflamed conditions remedies which are more active in
this direction often serve better, and tannin especially
will be found most valuable, especially about the head ;
thus, a very valuable combination is made as follows :

TBEATMENT IN DISEASES OF THE SKIN 35
Resorcin ( 3i ad 50 also acts as an astringent, and
salicylic acid, in what is known as Lassar's paste, has
often a wonderful control over sub-acute eczema. I
generally use it about as follows:
11. 1^ Pulv. acidi siilicylici . . . oss
Pulv. amyli 3i-3ii
Zinci oxidi 5ss-3J
Unguenti petrolat 5i
rr]^. ft. Unguent.
The various preparations of tar, to be mentioned next
under anti-pruritic remedies, also act strongly as astrin-
gents on the capillary circulation, although one con-
stantly meets skins which will not bear them at all.
As astringent lotions may be mentioned the ordinary
black wash, pure or diluted, which often acts most favor-
ably in ivy poisoning and erythematous conditions ; also
a boric acid lotion (3ss — 5i ad '^iy).
4. Anti-pruritic Applications. Many external reme-
dies have been advocated for the relief of itching, and
many are in common use ; but it must be acknowledged
that at times it is exceedingly difficult to secure satisfac-
tory results in special cases, one after another remedy
failing to give relief, and often proving irritating to
the eruption. Sometimes this is due to a faulty diag-
nosis, as, for instance, when scabies or eczema margina-
tum is present about the genital region, and very often
from a failure to use proper general, dietary or hygienic
treatment combined with the local. But at the best the
problem of itching in many cutaneous conditions is one
which often taxes the patience and skill of the physician
to the utmost.
36 PRINCIPLES AND APPLICATION OF LOCAL
The hint may be thrown out here that it is well to
begin with very mild preparations and increase the
strength cautiously, as occasion demands. Also it is
often desirable, when the part has been irritated by
attempts to relieve itching, to return to very mild appli-
cations.
The calamine and zinc lotion mentioned under sooth-
ing applications (Formula 3, p. 30) is often a most valu-
able application, and its anti-pruritic action may be
increased by doubling the amount of carbolic acid in it.
Carbolic acid undoubtedly stands first in our list of
anti-pruritics, and when one learns to use it well it will
prove of great service in many conditions of the skin ;
it can be added, one to three per cent., with advantage
to most lotions and ointments.
Ichthyol is very valuable, and may be used in solution
in water (10 to 25 per cent.) with satisfaction, painted
over a surface and left to dry on : and an ointment may
then be applied over it, if more protection is desired.
It is also serviceable in ointments, as in the following :
12. I^ Ichthyol 5ss-oi

The different preparations of tar aid greatly in con-
trolling pruritus, and may be employed in various com-
binations. In liquid form the "liquor picis alkalinus,"
wdiich I presented to the profession some time ago, has
received endorsement on all sides.

13. I^ Picis liquidsp 3ii

It is prepared by dissolving the caustic potash in the
water, and then adding this to the liquid tar, in a mortar,
with friction, until quite dissolved. This may bo used
diluted ten to twenty times with water, and bathed over
the parts, before applying other dressings. In more
chronic conditions it can be employed much stronger,
and the part even rubbed with it.
Preparations of tar combined in ointments are often
most effective in controlling itching. The following is
of especial value :

The anti-pruritic effect can be further heightened by
the addition of ichthyol, oil of cade, or oleum Rusci,
half to one drachm in the ounce : or these can be added
to other ointments.
For more general pruritus, where it is mild, the fol-
lowing ointment is often of the greatest service :

This combination, which I have called "skin food,"
is applied pretty freely with the palms, and gently
38 PEINCIPLES AND APPLICATION OF LOCAL
rubbed into the skin, until it is absorbed, leaving the
surface soft and supple. Ordinarily for treatment the
application should be made both morning and night,
but it may be used more frequently if desired, to relieve
itching : the anti-pruritic effect of the carbolic acid may
be heightened by the addition of about double the quan-
tity of menthol, although some object to the very cool
sensation produced by the latter.
Another very good general anti-pruritic is a combina-
tion of chloral and camphor in ointment, made as
follows :
16. I^ Chloral pulv.
Camphor gummi aa 36S-5i
Unguenti aquae rosae . ... 5i
TT^. ft. Unguent.
The camphor and chloral are rubbed together until
liquid results, and added to the cold cream, or the **skin
food" just mentioned, or the glycerite of starch, which
is a soft, ointment-like substance, very agreeable to
many. When the skin is at all raw or broken, this com-
bination of camphor and chloral will smart considerably,
but with unbroken skin it is very soothing.
In attempting to control itching, the effect of very
hot w^ater, and sometimes of very cold, must not be for-
gotten. In eczema and pruritus of the anus and geni-
tals, a cloth soaked in very hot water, hotter even than
the hand can well bear, is placed on the part and held
there for a few moments: it is then heated again and
held to it, and so for not more than two or three minutes
in all, and then, after quick drying with a hot, soft
towel, the appropriate ointment is instantly applied.
TREATME^•T IN DISEASES OF TUE SKIN 39
The ointment should not be nibbed on the part, as that
excites fresh itching, but spread on the woolly side of
lint, or a thin layer of absorbent cotton, and closely
fitted to the part. This often gives complete relief, cer-
tainly for a time. The use of the stramonium ointment,
in conjunction with that of tar and zinc (Formula 14,
p. 37), is valuable, likewise the addition of a little
aconite and belladonna helps greatly: cocaine, two to
five grains to the ounce, is also of service.

Voluntary or artificial restraint is often necessary in
order to prevent patients from scratching before the
anti-pruritic remedy has had a chance to act. The con-
trol of children with eczema will be spoken of later.
5. Emollient Applications. In many instances the
entire surface of the skin will be hard and more or less
scaly, the glands acting badly, and more or less emol-
lient applications may be needed for some time. The
"skin food" already mentioned (p. 37) is most advisable
for this, and the unguentum aquae rosae in it can well be
replaced by albolene. But where large quantities of
such a lubricating ointment are needed, as in the case of
ichthyosis in the boy aged 14, whom you recently saw so
marvelously changed, and on w^hom no less than half a
pound was used in a single thorough application, at
first, it becomes very expensive, and a cheap substitute
40 PBINCIPLES AND APPLICATION OF LOCAL
can be made at home: you saw this used in that case,
and I think it is worth remembering.
For this purpose I have the patient buy five pounds
of ordinary mutton suet at the butcher's. This is
chopped rather fine and boiled in water some hours,
with stirring. It is then set aside to cool, and the cake
which forms on the top is again boiled in water, with
stirring, and set to cool. The cake again formed is
then melted, and when liquid is mixed with a little
more than the same quantity of cod-liver oil, or linseed
oil, and stirred till cold, a little boro-glycerine, a tea-
spoonful to each oimce being added ; a few drops of oil
of lavender, bergamot, or geranium added to each ounce
makes it very attractive. This combination, which can
be very cheaply prepared, I have found to act quite as
well as the more expensive combination just mentioned.
Glycerite of starch, with one or two per cent, of carbolic
acid, also answers very well for some skins.
The essential thing is that sufficient of the ointment
be employed really to affect the skin. It must be used
with a lavish hand, and gently rubbed in, imtil the skin
will no longer soil the clothing.
6. Stimulant Applications. But all dermatological
treatment does not consist merely of these mild meas-
ures, calculated to soothe the surface ; for in many dis-
eased conditions there is a chronic thickening of the
skin, caused by an infiltration of deeper tissues, which
will not disappear except under stimulating treatment,
and as long as this infiltration persists the disease is
not cured.
In using any stimulating applications, however, one
TEEATMENT IN DISEASES OF THE SKIN 41
must ever bear in mind the delicate structure of the skin,
for excessive or wrong action can produce an irritation
of tissue, and an inflammatiou which may prove trouble-
some. Stimulating measures should, therefore, be used
more or less intermittently, and often with a soothing
treatment between.
A good illustration of what I mean is found in the
treatment of chronic eczema of the lower leg, which I
witnessed many times in Hebra's clinic in Vienna, and
which is often practiced in this hospital. Here the
thickened tissue is actually scrubbed with a brush dipped
in green soap, even until, as I have often seen, the
water in the basin may be red with blood. The part
is then quickly dried and completely enveloped in the
true diachylon ointment of Ilebra, already described (p.
33), spread on lint. The scrubbing allays the pruritus,
and the consequent exudation helps to relieve the en-
gorged vessels: if the effects are good this rough treat-
ment may be repeated wdth advantage each day, although
it is always better to wait somewhat longer after the first
trial of it, until one learns the reactive power of the part.
Ilebra also devised the compound tincture of green
18. I^ Saponis \nridis
Olei cadini
Spts. vini rectif aa 5i
n\. ft. Tinct. Saponis. Virid. Co.
soap, which may often be used with the best results in
stimulating indolent skin lesions.
Another illustration of the value of stimulating local
applications is found in the treatment of psoriasis.
Here the mild measures with which we began are totally
42 PEINCIPLES AND APPLICATION OF LOCAL
inefficacious, although they may at times be needed, and
all the local applications which are effective are of a
more or less stimulant character. The most striking of
these is chrysarobin, which, as you know, may excite a
very considerable degree of congestion and even inflam-
mation, when used in excess.
Most of the mercurial, sulphur, and other ointments
of the Dispensatory are stimulating, and in many in-
stances are far too irritating in the strength there
directed. It would take far too much of your time to
attempt to elaborate this subject in a thoroughly satis-
factory manner at the present time. I hope to speak
practically, in the later lectures, in regard to the
strength of ointments suitable for many diseased condi-
tions of the skin. I \vill only say here that great caution
and judgment are necessary to properly adapt stimu-
lating local applications to diseased surfaces.
7. Absorbent Applications. The next class of reme-
dies to be mentioned are those which produce absorption
of effused products in the skin; iodine, mercury, and
lead stand prominent among these. The following com-
bination often serves a valuable purpose, but may at
times prove too irritating, and must be diluted with
from two to four times the amount of cold cream or
albolene :
19. I^ Unguent i hydrargjTi
Unguenti iodi aa 5i
TT\. ft. Unguent.
These are rubbed together, and form, as I believe, a
nascent iodide of mercury, which is very penetrating,
TEEATMENT IN DISEASES OF THE SKIN 43
and is very ctHcacious in producing absorption of en-
larged glands, also of deep syphilitic deposits and nodes
in bones.
The iodide of lead is also most valuable in discussing
deep infiltrations of various kinds.
20. I^ Plumbi iodidi 3ss-3i

In certain thickened patches of lichen planus, and
also in some conditions of tylosis, the following oint-
ment, suggested first, I think, by Unna, is very efficient :

This may be rubbed in, and then the part covered v- ith
the same spread on lint.
8. Anti-parasitic Applications. The number of para-
siticides which have been recommended at various times
is very great and quite bewildering, and one hardly
knows how to explain the reported successes of many of
them in the hands of certain persons, and their failure
in the hands of others: except on the personal ground,
that one can often work best with a tool with which one
is best acquainted. I would advise you, therefore, not
to keep trying this or that ointment or application recom-
mended by however high an authority, much less those
advocated by advertising firms supported by assertions
of unknown men, often of little experience. It is best
to select a remedy, or remedies, and use them over and
44 PEINCIPLES AXD APPLICATION OF LOCAL
over again, with modifications if necessary, and so be-
come acquainted with what they can do and the best
maimer of employing them.
This class of applications may be divided into microb-
icides, and parasiticides proper. In the former lecture
it was mentioned that micro-organisms play a very con-
siderable part in the causation and continuance of many
cutaneous diseases, and it is continually necessary to
reckon with them. It was also mentioned that many of
the well-recognized local remedies had more or less bac-
teriocidal qualities, and these are often all that is
required.
Dermatitis seborrhoica, or seborrhoic eczema, is now
pretty generally recognized to be due to a micro-organ-
ism, and resorcin seems to be almost a specific against
it. On the scalp the trouble is often controlled really
remarkably by a lotion composed about as follows :
22. I^ Resorcin 5"
Spts. vini rectif oiii
Glycerini oiv
Aquae rossD ad 5iv
rr[. ft. Lotio.
This is applied night and morning, by means of a
long ^'hair dropper," and thoroughly rubbed in, with
shampooing every week or so.
On other parts of the body resorcin in ointment
proves more valuable, with or without a little sulphur.

TEEATMEXT IN DISEASES OF THE SKIN 45
When organisms causing pus are present and opera-
tive superficially, as in impetigo contagiosa, the anti-
septic properties of mercury are very efficient, thus :

Peroxide of hydrogen is also a most valuable aid in
connection with many suppurative conditions, and may
be freely applied, even in full strength, on bits of cotton
soaked with it, as on ulcers, before making other proper
applications.
Parasiticides proper refer to those destructive to
animal and vegetable parasites, and relate to a number
of different remedies. Their application to particular
diseases will be discussed later. It is proper here only
to throw out the caution that they be not made too strong,
to irritate the skin unduly, nor yet so weak as to be
inefficient. To secure at first the proper strength is
sometimes a matter of considerable difficulty.
9. Destructive Applications. Finally the remedies
which are needed in connection with the local treat-
ment of certain skin lesions may have to be decidedly
caustic or destructive in their action, in order to effect
the results desired. As examples of this may be men-
tioned the various caustic pastes, which have been rec-
ommended for the destruction of new growths, as epi-
thelioma, lupus, etc., some of which will be mentioned
later.
Happily the indiscriminate use of nitrate of silver
46 PEINCIPLES AND APPLICATION OF LOCAL
as a caustic to the skin, has largely passed away, al-
though it may occasionally be of some value. But the
habit of "touching up" local sores on the skin or in the
mouth, with a stick of nitrate of silver, has been pro-
ductive of harm, and has beyond question repeatedly
converted what would have been innocent lesions into
those of malignant nature, requiring very severe, even
surgical treatment. Nitrate of silver is a dangerous
remedy in unskilled hands.
I come now to speak, as briefly as possible, upon a
very important matter in connection \vith the local treat-
ment of diseases of the skin, which has already been
hinted at a number of times, namely :
2. Modes of Making Applications to the Skin, and the
Removal of the Same. In treating a patient with a
cutaneous affection, it must be taken for granted from
the first, and all through, that the individual really
knows nothing as to exactly the correct mode or method
of treating the diseased part: in the vast majority of
instances it is the first occasion in which the person has
had occasion to make such applications. Even in those
who have suffered from a cutaneous ailment for some
time, the same course must be taken, for one can never
be quite sure that the patient will do things just rightly:
indeed, owing, I suppose, to the "contrariety of animate
and inanimate objects" just the wrong thing is very
often actually done, unless specific instruction, and in
some instances patient demonstration, is given in regard
to exactly the right manner.
Never forget the importance of little things in derma-
tology. One cannot really be too careful to have just
TREATMENT IN DISEASES OF THE SKIN 47
the right thing done in the right manner and at the right
time, and undoubtedly a considerable share of the want
of full success comes just from the neglect of the princi-
ples stated.
The majority of patients when given an ointment or
a lotion will simply rub it over the affected part, whereas
very few of them are to be used in this manner; and
where they are intended to be applied with friction, few
patients will ever use them thus efficiently.
Remember that the first class of local applications
mentioned was under what is known as protective meas-
ures, and almost all cutaneous lesions require protection
from external influences, as well as dressings which shall
keep the medication in proper coaptation to the affected
part.
The mode of application of an ointment must vary
greatly according to the purpose for which it is used.
Thus, when an ointment is used for lubricating, as in
ichthyosis, xeroderma, or in a slight general eczematous
or pruritic condition, the ointment should be taken on
the palms and the surface freely anointed, with more
or less friction, morning and night, or as often as re-
quired, until much of it has been absorbed. Also in the
treatment of scabies the appropriate ointment should
be rubbed in with the palms, all over the affected parts,
and even for half an hour, until it has well penetrated
the furrows made by the insect, and a considerable quan-
tity should be left on, so that the underclothing becomes
pretty well saturated with it.
On the other hand, however, on a more or less raw
eczematous surface, such a procedure would be any-
48 PEIXCIPLES A^•D APPLICATION OF LOCAL
thing but beneficial, and the ointment should be thickly
spread on the woolly side of lint (some sav on the hard
side, but I am sure that this is a great mistake) and
firmly bound on the part, with as light a gauze bandage
as possible. The same is true when it is applied to such
a lesion as pemphigus or any abraded or ulcerating
surface.
I wish, however, to call your special attention to the
value of absorbent cotton under certain conditions, upon
thin layers of which, with a little care, ointments can
be spread satisfactorily. These may be made to fit
uneven surfaces, and on removal they will come off
easier, in pieces, and often do not do the violence to
tender surfaces which frequently occurs when the appli-
cation is made on a continuous sheet of lint. This
method is peculiarly suited to eczema about the anus
and genitals, and in hemorrhoids, as it can be well
tucked in and keeps in position. It is also very service-
able in eczema on the fingers and toes.
Between these two extremes there are varying degrees
of the active application of ointments often required,
and patients must be instructed just how to make them,
or much of the benefit will be lost. Thus, in parasitic
diseases of the scalp, after clipping the hair very short,
it is often well to apply the ointment with a stiff stencil
brush, cut short, with considerable friction, working
it well into the follicles ; the same mode of application
is also valuable in hard patches of psoriasis on all parts
of the body.
Again, in old patches of eczema, there is often much
benefit from a greater or less degree of friction with
TEEATMENT IN DISEASES OF THE SKIN 49
the finger, or often with a bit of flannel dipped in the
ointment, after which the patch is covered with the
same spread on the woolly side of lint and bound firmly
in place. In many cases of eczema and psoriasis about
the hands, it is almost impossible to make any progress
unless the proper ointment is kept bound on the affected
part all the time, night and day, for a while. In eczema
in small children, the direction should be to replace it
as often as it is rubbed off, or when the dressing becomes
at all deranged.
Often one sees very poor results in the use of oint-
ments resulting from the coverings or dressings which
are placed over them. Thus, a diseased surface to
which ointment has been applied is often found to be
covered with old linen or surgical gauze ; these readily
absorb the greasy portion of the ointment, and leave the
affected portion dry, perhaps coated only wdth the min-
eral or other ingredient contained in it. Be sure to
insist on lint or absorbent cotton being used.
Many errors also continually occur unless careful
and explicit directions are given by the physician, in
regard to the removal of ointments, and the subsequent
treatment of diseased surfaces. Remember that even
nurses are not often specially trained in this particular
branch of medicine, and also that they may have been
wrongly directed by others.
It seems to be the universal idea that diseased sur-
faces should be frequently washed, and one continually
finds healing prevented by the application of soap and
water, daily or oftener. Rarely is it advisable to wash
surfaces which are at all raw, and all the cleansing
50 PEINCIPLES AND APPLICATION OF LOCAL
necessary to them can generally be accomplished by the
gentlest wiping with absorbent cotton.
Much harm is also often done by a rough removal of
ointments and dressings. When the latter adhere too
closely it is generally because there has been too little
ointment used, or an improper covering made. Let me
urge you to insist on a very free, even lavish, use of
external applications. If, on the removal of a dressing,
there is much ointment on the skin, which it is desira-
ble to remove, this can commonly be best accomplished
by means of a dull knife, if gentle wiping with absorb-
ent cotton is not effective.
Quite as many errors also occur in the use of lotions
and powders, unless careful, specific directions are given.
You have all seen in the clinic the use of the calamine
and zinc lotion (Formula 3, p. 30), which proves so
serviceable in acute erythematous and papular condi-
tions. Now this does its good by leaving a more or less
thick coating of the solid ingredients on the skin: the
same is true of the magnesia and zinc, and some other
lotions. To accomplish this in the best manner, I
direct that, after being well shaken, some of it shall
be poured out, into a dish with a cover, and freely
sopped over the surface with a bit of handkerchief.
Absorbent cotton does not answer, as it holds too much
of the powder in its meshes, as does also lint ; of course
a sponge should never be employed. For the evening
dressing I always have two thorough applications made,
the second about ten minutes after the first, in order to
ensure a sufficient coating. The covered dish, with
some of the lotion in it, is then placed by the bed, so
TREATMENT IN DISEASES OF THE SKIN 61
that a little more can be sopped on in the night if
needed; or, the bit of cloth dampened with it can be
laid on any particular part that itches. In the morning
a single coating is generally sutiicient, on top of what
remains of that applied the night before.
Much the same rule applies to the employment of the
lotio alba or other lotions in acne, to be mentioned later.
On the other hand, some applications, as that of
ichthyol in solution, or per-manganate of potassa, or
the diluted liquor picis alkalinus, already described,
(p. 37) give their best results by being lightly patted or
wiped over the surface, and left to dry on.
Mistakes are continually made in covering applica-
tions to the skin, whether of ointments or lotions, with
an impermeable dressing, as oiled silk, or rubber tissue :
this often macerates the parts and defeats the very
object of treatment. When a covering is needed in
order to protect the clothing, I direct the use of one or
more thicknesses of good flannel, which does not heat
and macerate the part, and does not absorb the greasy
matter, as would cotton or linen.
An exception to this avoidance of impermeable dress-
ings is found in waxed paper, which sometimes serves
a very valuable purpose, especially in chronic patches
of lichen planus, eczema, or psoriasis. On the legs, or
places where there is not much movement, it often acts
like a plaster; after rubbing in the proper ointment
well, a trifle can be wiped on the paper, and if this is
well pressed down, and air excluded, it will easily stay
in place all day.
Another exception in regard to an impermeable dress-
52 PEINCIPLES AXD APPLICATION OF LOCAL
ing is found in the use of the solid rubber bandage in
eczema and ulcers of the lower leg, which I shall hope
to demonstrate again to you when I come to speak more
particularly of the local treatment of special diseases
of the skin.
I must call your attention to one very valuable means
of keeping dressings in place, on certain parts, and that
is what is known as the circular bandage: this name
was given to it because it was originally sold in circles,
or bands, but I prefer to have patients buy the material
and make it up in exactly the size required. It consists
in an elastic webbing, about three inches wide, like an
exaggerated garter, bought by the yard. It should not
be made to fit too closely, but just tight enough to grasp
the part so that it shall not slip : this is, of course,
applicable mainly to the arms and legs. Where a wider
surface is to be covered, several such bandages may be
used, and I sometimes have them sewed together, making
a broad band, but generally it is better to have them sepa-
rate. Absorbent cotton, in a thin layer, should always
be used beneath them, as any ointment will injure the
elasticity of the rubber. For years I have employed
this means of keeping dressings on the limbs, with most
satisfactory results.
A few words may be added, in closing, as to
3. The General Treatment of the Skin, especially in
those at all subject to cutaneous alfections, including
the subject of bathing; and I will first repeat a sentence
or tA/o w^hich I gave last year, referring to those lectures
for a fuller consideration of the subject.
The tendency of modern times is to the free use of
TREATMENT IN DISEASES OF THE SKIN 53
water externally, and in many instances this will be
carried to an injurious extent by patients with various
affections of the skin. From long observation I have
been led to share the view of Ilebra, who, toward the
close of his life, wrote very strongly to the effect that
the matter of bathing was constantly overdone: he
stated that he saw more eruptions in those who were
active bathers than in those who neglected the skin in
this respect. I have very many times heard private
patients state that they had uiuch less trouble with the
skin when they were traveling, and when they could not
secure great bathing facilities, than when they were at
home and indulged freely.
It is important, of course, that the surface be kept in
a proper condition; although I think that a great deal
that is said about ^'keeping tlie pores open" is unneces-
sary and irrational ; animals do not bathe, and yet in
them the skin performs its functions satisfactorily. A
certain amount of bathing for cleanliness is rational,
but as sometimes practiced it is unnecessary and very
frequently harmful.
I have previously mentioned tlie harm from washing
diseased parts, and especially with castile soap, as is
so common.
Soaps. One is constantly asked as to what soap is
good for the skin, and especially in regard to some of the
medicated soaps so alluringly advertised to the profes-
sion and public.
To tell the truth, I believe that it makes very little
difference what soap is used, if only it is a good one,
with not too much alkali. The ordinary hand soaps,
54 PEIXCIPLES AND APPLICATION OF LOCAL
from the best makers, are, as a rule, all good, and I
have direct personal information that one at least of the
much advertised special skin soaps is only ordinary soap
taken from the general stock of a certain good manu-
facturer, and specially stamped for the purpose. I
spoke a moment ago against castile soap: I object to
this, as it is a soda soap, and therefore not as suitable
to the skin as one which is made with potash.
I am not a believer in the many medicated soaps put
forth by special houses, principally abroad, though, of
course, I have used them more or less in my practice.
But I do not see how medicaments can be efficient when
used in this manner. Tar soap, however, is somewhat
of an exception, and seems relatively unirritating to
eczematous surfaces, and I employ it more or less.
There is no intrinsic reason why soap should not be
used on the face, but in acne I generally advise that the
face be washed, in the morning with cold water and
without soap, the palms of the hands being used instead
of a wash-cloth, and that considerable friction and self-
massage be applied: after this the surface is quickly
dried, with a soft towel, and the appropriate lotion im-
mediately applied. ^Mien we come to speak of dis-
eases of the scalp, I will try to describe what I consider
the best method of shampooing.
I cannot quite close this lecture without giving you a
suggestion or two in regard to the preparation of the
applications which are to be made to diseased skin : for
I constantly see many which are prepared in a very bad
manner. You cannot be too careful in seeing to it that
not only are ointments and lotions compounded exactly
TBEATMENT IN DISEASES OF THE SKIN 65
as prescribed, but also that tbey are free from gritty
particles, whicli will irritate diseased skin. It is well
to have the solid ingredients lirst ground fine in a mor-
tar, and mixed with a drop or two of almond oil, before
being mingled with the base : I once saw an ointment of
red oxide of mercury which I had ordered for the eye-
lids, containing large particles of gritty substance like
red sand, stirred in the mass. Lotions, likewise, should
not have any gritty matter in them. Remember, also,
that the least rancidity in the ointment will act very
prejudicially. It is well for the physician to frequently
inspect all remedies used by the patient, especially those
used for local application.
In the next lecture I shall expect to take up the mat-
ter of the personal local treatment of certain cutaneous
affections, including surgery, and the use of electricity
in various forms. X-ray, Finsen light, etc. I shall also
begin the consideration of the local treatment of special
diseases, and will mention as many of them as possible
in that and the following, concluding lecture.

Gentlemen :
We come now to consider some of the various aids to
the local treatment of certain diseases of the skin which
may be given bv the physician, or under his immediate
guidance. These may be divided into: 1. Personal
local manipulation ; 2. Dermatological surgery ; and,
3. Electrical and radial energy.
I. Personal Local Manipulation. There are not many
cutaneous affections in which personal manipulation is
required, but in certain instances it may be of very
great advantage.
Acne will commonly yield to careful internal treat-
ment, with proper dietetic and hygienic care, aided by
proper local a]i])lications ; but in some cases the progress
can be very greatly accelerated by right personal pro-
cedures, while in occasional instances these are very
necessary.
We saw, in our study of the anatomy of the skin, that
the sebaceous glands often fail in their proper action,
56
TREATMENT IN DISEASES OF THE SKIN 67
and that the liuiug cells instead of undergoing liquid
transformation, accumulate, forming cheesy masses or
j)lugs, called comedos or ''black-heads" ; these from their
size cannot escape without aid, and if left in situ are
not only a disfigurement, but also tend to inflame and
cause acne pustules. I do not allow patients to try to
remove them, as by a watch key, or pressure, for they
invariably bruise the face, and very often do not succeed
completely ; I prefer to extract as many of them as pos-
sible, by means of a small silver tube, whose ends are
made conical, sold by the instrument makers under my
name ; with firm pressure over the little masses, and with
a little sudden jolt, they are easily made to extrude and
the gland completely emptied : in certain cases the bene-
fit from this little procedure is really very great.
Also in pustular acne, the opening of the lesions, and
even the free bleeding of the surface by means of the
acne lance, which you have often seen used in the clinic,
results in the greatest benefit. In the larger lesions of
acne indurata, where there are indolent abscesses in the
skin, these should be opened by a horizontal cut, with a
good sized acne lance, on a level with the adjoining sur-
face and at the most dependent point; and in some of
these cases I scrape the inside of the cavity with a very
small curette, to remove the degenerated cells and excite
healthy inflammation.
In some cases where there are very many, rather
small pustular lesions, the dermal curette can be used
with much advantage, scraping off the tops of the lesions,
and dragging out the sebaceous plugs, even causing some
bleeding. By these means a surprising improvement
58 PEINCIPLES AND APPLICATION OF LOCAL
can be effected in a very short time. Occasionally it
is desirable to bathe the face with warm water, directly
afterwards, to encourage the bleeding, although, as you
have often heard me say to patients, I believe that the
face should generally be bathed with cold water. I do
not approve of steaming the face.
These procedures need seldom leave any scars if prop-
erly done, for in the main it is only the epidermal layer
which is affected by them ; the scars so often observed in
old cases of acne are the result of neglected lesions,
which have already caused destruction of deeper tissues.
Some good may also be accomplished by the proper
massage of the face, when there is not much inflamma-
tion; but my experience has shown me that, as usually
practiced by advertising quacks and uneducated persons,
more harm than good is often done. On washing the
face, with the hands, a certain amount of self-massage
may be practiced with advantage, and the physician can
do a certain amount of it and demonstrate the manner
of the procedure to the patient.
Personal manipulation can often be utilized in the
way of epilation in cases of ringworm and iavxis of the
scalp, where the attendants do not understand the proc-
ess, or will not do it properly.
The application of the rubber bandage, which you
have seen me use in cases of eczema and ulcer of the leg,
should always be made first by the physician, both to
test the immediate effect of its employment, and in
order that the patient may understand perfectly just
how it is to be applied: it is often desirable for the
physician to readjust it personally, at subsequent visits.
TREATMENT IN DISEASES OF THE SKIN 59
Finally it is frequently advisable for the physician to
demonstrate, and even to make the first application of
some lotions and ointments, for as I remarked in the
last lecture, patients are conmionly ignorant of just the
best methods of their emplo^Tnent.
2. Dermatological Surgery. While not commonly
extensive, there may at times be considerable surgery
connected with dermatological practice. Operations on
epithelioma, sarcoma, and tumors may in some cases be
very serious, and considerable surgical skill may be re-
quired in plastic operations and skin grafting, as after
the excision of lupus and epithelioma. Some cases of
vascular nsevus, where it is at all deeply seated, or
angiomatous, are best treated by complete surgical re-
moval with plastic operation or skin grafting, as are
also certain cases of pigmentary nsevi. Elephantiasis
of the scrotum or penis can only be treated successfully
by surgery, and in some cases of ulcers of the leg ex-
cision and skin grafting give the best success : the sur-
gical operation of tying or removing varicose veins is
also a valuable aid in curing certain conditions on the
lower extremities.
Among less severe surgical procedures may be men-
tioned the curetting of epithelioma and lupus, or boring
them out with the dental burr, or with sticks of nitrate
of silver, as you have seen me do in the clinic. Warts
may also be successfully removed by the curette. The
small tumors of molluscum pendulum, seen so often on
the necks of females, may be snipped off with the scis-
sors very easily, and the wounds heal readily, leaving no
scar ; sometimes it may be desirable thus to remove those
60 PRINCIPLES AND APPLICATION OF LOCAL
of molluscum contagiosum, or bore them out with a stick
of nitrate of silver.
Cutaneous or glandular abscesses may also require
incision, also boils and carbuncles, although, as I shall
hope to show in the next lecture, I much prefer other
treatment, and rarely if ever cut the latter.
The thermal or electro-cautery is sometimes of value
in dermatology, in destroying small lesions and after
curetting operations on epithelioma and lupus. I have
also used it successfully on vascular nsevi, by making
very many superficial parallel linear cauterizations, so
as to destroy the outer blood vessels: if this is done very
delicately there need be hardly any scar, and often prac-
tically none. The dilated and prominent capillaries in
acne rosacse are also often easily obliterated by means
of the electro-cautery needle.
Liquid air may be mentioned here, the use of which
has often given excellent results in naevus, and also in
a number of cutaneous conditions, such as epithelioma,
lupus vulgaris and erythematosus, and others.
A clever application of cold has recently been recom-
mended by Dr. Cathcart of Texas.* He cured a num-
ber of cases of "creeping disease," due to the burrowing
of the larva of a certain species of fly, by freezing the
terminal or advancing portion, by means of ethyl chlo-
ride: a single thorough application was sufficient in
each instance to kill the parasite and cure the disease.
The cutaneous punch may be mentioned as at times
a useful instrument in removing small moles, and also
in securing portions of diseased skin for microscopic

examination. The smaller sizes may be employed for
removing powder marks from the skin.
3. Electrical and Radiant Energy. These relatively
new agents which have been introduced into medicine
have an ever widening application in dermatology, and
often prove of the most signal advantage in many cuta-
neous conditions. We will consider them under the
several heads of, 1. Electrolysis; 2. Static electricity;
3. Galvanic current ; 4. Faradic current ; 5. High
frequency current ; 6. X-ray ; 7. Radio-activity, and
8. Photo-therapy and the Finscn light. It will be im-
possible in the time at our disposal to consider any of
them at all completely, and I will only indicate some
points which I think desirable to keep in mind in deal-
ing with dormatological cases.
1. Electrolysis. It is not necessary here to enlarge
upon the theory of electrolytic action; suffice it to say
that it depends upon well-kno^\Ti laws of electro-chemic
action, whereby the tissues of the body are altered and
decomposed, certain elements tending to the positive
pole and others to the negative. In some conditions, as
in nsevi, needles attached to both poles are introduced,
the bi-polar method : in others the uni-polar method is
used, one needle being attached to one pole, while the
other is located elsewhere on the body.
This latter method is employed in electrolysis for the
removal of superfluous hairs, hirsuiies, or hypertricho-
sis, and the needle is attached to the kathode, or negative
pole, the positive pole being held in the patient's hand,
with a moist electrode. After the needle is in position,
being inserted about one-quarter of an inch along the
62 PKIXCIPLES AND APPLICATION OF LOCAL
hair, a mild current of about one milliampere is turned
on for from 10 to 30 seconds: the current can be made
and broken bj the patient touching the sponge, but I
much prefer to have a small electric button in the cir-
cuit, which can be pressed by the operator's foot. When
the current is acting, small bubbles of gas (hydrogen)
are seen at the orifice of the follicle, and on removing
the needle the hair is found to be loose in its socket, and
can be removed with the slightest traction.
This process is radically curative, for if the papilla
has been reached and destroyed the hair does not regrow.
For more details I must refer you to some of the many
reports which have been made on the subject in lit-
erature.
Bi-polar electrolysis is sometimes serviceable in treat-
ing cases of deep-seated vascular n8e\T^is, especially about
the face, when radical surgical measures might involve
too much scar ; but in my hands it has not been as satis-
factory as might be expected from what has been written
about it.
2. Static Electricity has its value more in general ap-
plications as a nen'^e tonic, and in relieving pain, and
often in cheeking general itching ; the static breeze has
also a favorable effect on the scalp in ordinary alopecia,
and somewhat so in alopecia areata.
3. Galvanic Current. Rockwell* still claims for
central galvanization a most profoundly beneficial effect
on the general system, "through the brain, s\inpatlietic,
and spinal cord, as well as the pneumogastric and de-
* Rockwell, Med. and Surg. Uses of Electricity. New York
190.5, pp. 338, 342.
TREATMENT IN DISEASES OF THE SKIN 63
pressor nerve" ; he further states, referring to eczema
and prurigo, "Under this method of treatment alone,
without making any application whatever to the diseased
surface, the itching and burning of these diseases are
relieved, sometimes immediately, and under a protracted
treatment permanent cures are obtained." I am sorry
to say that I can give you little personal experience in
the matter, and must confess to having neglected some
of the uses of electricity too much in my practice. I
believe, however, that there is a large field for its use-
fulness in more lines in dermatology, and hope that next
year I can give you more satisfactory personal experi-
ence in the matter. In what is said of the value of
electricity here, I wish, however, to have it clearly
understood that I accept it, in most instances only as
an addition to our armamentarium, in suitable cases,
and by no means to the exclusion of proper general and
local treatment such as I have often detailed.
The beneficial effect of the galvanic current in con-
trolling the pain sometimes attending herpes zoster, is
well known, and this I can verify.
4. Faradic Current. This also has its value in cer-
tain conditions of the skin, as many have testified, and
may be used either as general faradization, or applied
locally. One good application will very often quite
arrest itching, although, of course, it is not expected
that brief treatment will be permanent ; but as a means
of restoring nervous equilibrium it certainly has its
value, and locally stimulating applications of it restore
tone to weakened tissue.
5. High-Frequency Currents. With the rapid march
64 PRINCIPLES AND APPLICATION OF LOCAL
of science new developments in regard to electricity are
constantly presented, and will undoubtedly occur, and
we shall understand better the action on the body of
the different forms or modalities which this mysterious
something may assume. One of the latest of these is
what is known as the hyper-static, or more than static,
current ; that is, it is one of high frequency of alterna-
tion, having peculiar features, which have a pretty wide
range of usefulness in many cutaneous affections.
It is perhaps a little too soon to attempt to state at all
definitely what can be accomplished by hyper-static
electricity, but from the strong statements of those who
have carefully studied its effects on the nervous system,
and through the sympathetic and vaso-motor ner^^es on
the capillary circulation, we can well understand some
of the results which have been reported. Thus, one
well known observer says : ''My use has been chiefly in
connection with chronic, infiltrated eczema, rosacea, lo-
calized pruritus, pityriasis capitis, the localized eczema
seborrhoicum, and seborrhoea oleosum, in all of which
resolution of the lesions has been accomplished more
rapidly than by any means previously at my command."
My experience certainly confirms much that has been
said in regard to the value of the hyper-static electricity ;
it removes infiltrated patches of eczema and lichen
planus, and lupus erythemateous will sometimes yield
to it admirably; and with a carbon electrode it is very
effective in removing moles, especially from the face,
and warts from the scalp, and in two cases of superficial
vascular naevus it restored portions of the skin to a
normal condition.
TREATMENT IN DISEASES OF THE SKIN 65
6. X-7-ay. I need not detain you to speak of the
advantage of the X-ray in dermal therapeutics, for its
value has been too detinitely shown already to need
further evidence at this time. The only danger is that
many will use it recklessly or in unsuitable cases. The
results obtained by means of it in certain forms of epi-
thelioma, especially about the face, are certainly most
remarkable and among the most brilliant achievements
in modern science : and you have seen at the clinic some
very striking cases where the skin was left in an almost
normal condition after the cure of epithelioma by X-ray.
But it has been pretty well proved that it has very little
value in treating malignant disease below the skin, and
time is only lost in attempting to treat cases of cancer
of the breast or of other deeper organs, which are suita-
ble for other procedures ; although in certain inoperable
cases, and especially in those recurrent after operation,
it has sometimes been of the greatest benefit.
You have seen in the clinic this winter some of the
remarkable results which we have obtained by means
of it in ring\vorm and favus of the scalp, with the
luxuriant growi:h of healthy hair afterward; you have
also seen some striking results in removing patches of
psoriasis and lupus, likewise the surprising benefit to
the man with pigmentary sarcoma of the hands and
feet : last year you saw" in the clinic a woman with
Darier's disease, affecting the feet so badly that she had
been in bed for months, helpless, in spite of all treat-
ment ; this woman walked well, and left the hospital
apparently cured, after X-ray treatment for, I think,
about two months.
66 PEINCIPLES AND APPLICATION OF LOCAL
■ But the X-ray is a dangerous weapon in the hands
of the unskilled, and we must ever remember the serious
nature of some burns resulting from it; of these we
have had several instances under treatment in the hos-
pital, which, however, were produced outside of the
institution, by other hands. We have sometimes had
mild bums which healed under the continuous use of dry
dressing with the following powder:
25. I^ Aristol

7. Radio- Activity. Again time forbids the discussion
of this most interesting addition which has been made
to cutaneous therapeutics. Radium, which exhibits this
agency in the most striking manner, is certainly capable
of affecting the skin and tissues, as there have been
several instances of severe burns from its prolonged
influence. Some of the earlier reports from Paris in
regard to the beneficial influence from its use in lupus
were very startling, and very much was hoped from it.
Some of you may remember our using radium in this
clinic year before last, and some cases of lupus and
epithelioma were shown, where there appeared to be
decided improvement : but I am sorry to say from what
I observed during those months I was not convinced
that the results were equal to those obtained from the
X-ray; recently Dr. Abbe has reported very favorably
on its employment. I believe that it has a field of
operation in reaching malignant diseases of internal
cavities, where the X-ray cannot be made to penetrate,
TREATMENT IN DISEASES OF THE SKIN 67
but where radium, enclosed in a glass receptacle, can
be located and loft in place the proper time to produce
its alterative elfects.
8. Photo-Therapy and the Finsen Light. I can only
mention, in the very briefest manner, the subject of
light-treatment, which, while its importance has been
sometimes exaggerated by enthusiasts, has elements
worthy of careful consideration by those having to do
with certain diseases of the skin. I must refer you to
literature in regard to the effects of sunlight and elec-
tric light, in their entirety, and also as to the effects of
red light, blue light, the violet, and ultra-violet rays,
all of which liave been reported on more or less favor-
ably in regard to various cutaneous conditions.
I wish, however, to say a few words in regard to the
use of the Finsen light, w^hich I observed personally
for quite a while in Copenhagen. But no words can
express fully w^hat it has accomplished for the hundreds
of cases of lupus which have been treated there; they
are simply astounding, and the many cases which have
been brought from Copenhagen to the last two Interna-
tional Dermatological Congresses, in Paris and Berlin,
excited the wonder and admiration of all who saw their
original photogra])hs and examined the cured patients;
there could be no question as to the brilliant results.
I have not time to describe the treatment, but will
only say that it is extremely tedious, often lasting sev-
eral years in extensive cases, requiring daily applica-
tions of the light, over a small area, with the constant
attendance of a nurse, to hold the lens, for an hour, at
each sitting. The trouble and necessary cost are almost
68 PRINCIPLES AND APPLICATION OF LOCAL
prohibitive here, but while there I saw American pa-
tients who were quite satisfied with the continued
improvement daily observed. From what I observed
I believe that the peculiarly excellent results obtained
from this treatment in Copenhagen is largely due to
the most careful daily study of each case, by physicians
familiar with the treatment and its effects, who directed
each application: and a considerable share of the im-
provement is also due to the various medicated dressings
which were put on the diseased surfaces, by competent
nurses, and worn all the time, day and night.
You know, perhaps, that sunlight, focused by con-
densors, was originally employed, but for many years
the light is obtained from an electric arc light.
We have thus seen that electricity has an important
place in the dermatological armamentarium, but it
should always be kept in its proper place, and should be
no more over-estimated than under-estimated. I hope
that next year I may be able to present the subject very
fully, perhaps giving up the four special lectures to a
complete study of the value and method of use of elec-
tricity in connection with diseases of the skin.
We come now to the more practical and, perhaps, to
some, the more interesting portion of our subject,
namely, the direct application of the facts and princi-
ples already given to the cure of certain diseases of the
skin, at least so far as this can be aided by local treat-
ment.
Eczema. We will begin with eczema, as you might
expect, as it is the most frequent disease of the skin.
TBEATMENT IN DISEASES OF THE SKIN 69
forming in dermatological statistics nearly one-third of
all cases, and in general practice probably a very much
larger proportion.
But there is another reason for taking eczema first.
It has been called the "Keystone of Dermatology," and
he who understands its treatment will not only relieve
many distressing cases, but has also learned much of
the principles of dermal therapeutics, which may then
be applied to various cutaneous diseases.
But let me again warn you not to put too much trust
in local treatment alone, but, on the basis of what I
said in the special lectures last year, study the patient
in all particulars, and seek by all means, dietary, hy-
gienic, and medicinal, to remove the conditions which
predispose to, and often cause, eczema and other dis-
eases of the skin.
As eczema often begins very early in life, let us
consider first some practical points in connection with
the local treatment of infantile eczema.
Remember the exceedingly delicate and sensitive
skin of the infant, which, after its w^arm and moist sur-
roundings for many months, in utero, is endeavoring to
accommodate itself to its new surrounding circum-
stances.
First. I think that all babies are washed too much.
We all know the harmful results of the excessive use
of water and soap on the adult skin, as seen in washer-
women and others ; and you will remember that in the
preceding lecture, and also last year, I quoted Hebra,
the master dermatologist, who, toward the close of his
life, asserted strongly that he saw more skin eruptions
70 PRINCIPLES AND APPLICATION OF LOCAL
in those who bathed freely than in those who rather
neglected it. It may seem strange, in this day of count-
less bathrooms, but I fully endorse Hebra, and have
constant occasion in my office to discountenance the too
free use of bathing. What then must be the free use
of water, and all kinds of soap, on the baby's delicate
cuticle ? Babies with a tendency to eczema should be
especially guarded in this respect ; many an eruption has
been lighted up or aggravated by injudicious bathing,
if, indeed, it has not been caused thereby.
Second. Bearing in mind the delicate skin of the
baby, the first applications should be of the mildest
character. Fortunately we have in the oxide of zinc a
mildly astringent remedy which suits most skins ; I use
it, half a drachm to the ounce of good, fresh cold cream,
with five grains of carbolic acid to the ounce, never
just the zinc ointment of the Pharmacopoeia. A little
finely prepared calamine, twenty grains to the ounce
(Formula 6, p. 33), seems to help it. Bismuth sub-
nitrate or boric acid, of either thirty grains to the
ounce, suits some skins better (Formula 7, p. 34).
When there is much itching, the tarry ointment, men-
tioned in the last lecture (Formula 14, p. 37), will
often be all that is required, or the oil of cade, half a
drachm, may be added to the zinc or other ointment.
Ichthyol is also valuable for this purpose, half a drachm
to the ounce.
When there is more infiltration, or thickening of the
skin, other ingredients may be cautiously added, and I
have seen the following ointment succeed when others
failed :

It is rarely necessary to employ other remedies than
have been mentioned, if they are properly prepared and
used in the manner detailed in the last lecture.
But it is very necessary that the applications should
be correctly made and kept continuously applied, and
that the infant be prevented from displacing them, or
rubbing or scratching the affected parts; and this will
often be a difficult thing to accomplish.
For many years I have been accustomed to use a
very simple yet effective method of controlling infants
and preventing them from scratching, which I will
demonstrate to you. This consists of a small pillow-
case fitted over the child, the head protruding from a
hole cut in the closed end. It is drawn down, the arms
are pinned into the sides, and the whole is kept in place
with a large safety pin, between the legs. Many mothers
have spoken in the greatest praise of this method.
There is a clever patented device sold, I think, under
the name of "Scratch Not," which consists of stiff, cellu-
loid sleeves, attached to the shoulders, which prevent
bending the arms, and so reaching the face: much the
same can be improvised from heavy cardboard. There
is also another patented device recently put on the mar-
ket under the name, "Hand-I-Hold" babe mitts, which
is very effective. It consists of hollow, aluminum balls.
72 PEINCIPLES AND APPLICATION OF LOCAL
very light, with sleeves attached, which are drawn over
the arms and pinned to the clothing: the hands being
within the ventilated balls scratching is impossible.
I rarely use a mask on the face, though occasionally
it is necessary ; I insist that the attendant shall replace
the ointment whenever the child rubs it off, on the pil-
low or elsewhere. Sometimes the ointment can be
spread on bits of cotton, as described in the last lecture,
and the head lightly bound up if necessary.
On the body and limbs the ointment should be thickly
spread on lint, and lightly bound on. Sometimes, when
there is a mild general eczema, erythematous or papular
in character, the calamine and zinc lotion (Formula 3,
p. 30) suits quite as well in children as in adults.
Sometimes the intertriginous eczema of the anal and
genital region will be very troublesome, owing to the
constant soiling and necessary cleansing of the parts.
One constantly sees infants where, in the attempt to
dry up the sticky secretion from the red, raw surface,
powders have been used, which accumulate and form
a pasty mass, keeping up the irritation. The parts
should, of course, be occasionally cleansed, but very
gently, with a weak borax solution, and an appropriate
application immediately made. Ichthyol in watery
solution, about ten per cent., bathed over the part re-
lieves the itching and disinfects the surface. The ap-
propriate ointment is then laid on, spread on lint. A
mild boric acid solution, or one of acetate of aluminum,
two to ten per cent., serves the same purpose.
Occasionally the dressings will be found to adhere
to an eczematous surface, and frequently violence is
TREATMENT IN DISEASES OF THE SKIN 73
done to the tender tissues beneath by their harsh re-
moval. If sufficient ointment is used this need seldom
occur; when they are adherent they should be softened
by free applications of oil, left to soak in, and then be
gently removed, and suitable remedies immediately reap-
plied. It is well to have the fresh dressings already
spread, before the old ones are removed.
A word or two now in regard to eczema at the other
end of life, that is, in elderly persons. In them the skin
has undergone changes which make it quite diflferent
from that of infantile life; there is more or less of
atrophy of all its tissues, and a tendency for the epi-
thelial layer to undergo cornification and the glands to
act poorly. For localized patches of eczema the same
treatment is applicable, as will be mentioned in regard
to various localities in general. But often there is a gen-
eral irritability of the skin which needs attention, and
the very free use of the compound lanolin ointment,
described as "skin food" in the last lecture (Formula
15, p. 37), will be found to be most serviceable. When
there is a more congested, erythematous or papular con-
dition the calamine and zinc lotion (p. 30) affords the
greatest relief. It is well to remember, however, that
one can easily get chilled in making watery applica-
tions to large surfaces, and, in addition to being in an
extra warm room, I commonly direct that the bottle of
lotion be heated, and also that the receptacle into which
it is poured w^hen used, be likewise warmed; often the
skin will be too much dried by the lotion, and it is de-
sirable to alternate it with the use of the ointment.
When the itching is considerable, even without much
74 PEIUCIPLES AND APPLICATION OF LOCAL
eruption, ichthyol, in from ten to twenty-five per cent,
watery solution, painted over and allowed to dry on, is
very satisfactory.
It will perhaps be best to speak of the local treatment
of eczema as it affects various localities.
Upon the scalp^ as you know, we have a great deal of
seborrhoeic eczema, now called dermatitis seborrhoeica ;
it is really an eczema, of low grade, excited by the pres-
ence of a micro-organism. For this condition resorcin in
a watery lotion seems to be almost a specific (Formula
22, p. 44).
To be of real service it should be applied with a "hair
dropper" night and morning, and gently rubbed into the
scalp with the tips of the fingers. If there is some ten-
derness and inflammation, this may not always suit,
and in these cases I have had great satisfaction from
the use of the following lotion, applied in the same
manner :

When there is still a more acute condition, the tannin
ointment, of which I spoke in the last lecture (Formula
9, p. 34), is most excellent. This is also of value about
the ears.
The scalp should not be washed much, and always
very carefully, both in the cleansing and drying. I use
almost wholly a tincture of green soap, which is valu-

other conditions of the scalp.

This is inserted among the hairs by means of a "hair
dropper," and a very little hot water is added, with the
tips of the lingers, and gently rubbed until a lather is
formed. The scalp is then rinsed in the basin of hot
water, and then immediately in cold water, so as
to get the shock. I always have it dried with soft,
old, fluffy hand towels, w^hich have been baked in
the oven for half an hour and kept hot in a blanket,
in which the heavy earthenware dish in which they were
baked is also included. For a woman's scalp I order
six towels, for a man's, four. They are all to be used,
for the effect of the heat, they being taken out singly
from within the blanket. The appropriate lotion or
ointment should be reapplied immediately that the hair
is dry, and then morning and night thereafter.
Eczema on the face differs in different cases so greatly
that it is difficult to state succinctly a treatment suitable
to all. I am coming more and more to use the Lassar
salicylic acid paste (Formula 11, p. 35), where there
is a sub-acute condition, but where there is much con-
gestion the calamine and zinc lotion (Formula 3, p. 30)
serves best, for a while at least. A zinc and calamine
ointment (Formula 6, p. 33) is very beneficial, if kept
well applied, and this is particularly serviceable about
76 PEIXCIPLES AND APPLICATION OF LOCAL
the lips and within the nose. When there is a sebor-
rhoeic element in the eczema, a little resorcin, two to five
per cent., may be added to ointments with advantage.
Eczema of the hands may be very acute and distress-
ing, and it is here that we are most apt to find vesicles,
which are commonly so conspicuously absent in a con-
siderable proportion of eczema cases in general. And
these deep-seated vesicles will be the source of the great-
est suffering, and are sometimes very difficult to check.
The patient will frequently tear the surface violently,
even using blunt or sharp instruments to reach the deep-
seated source of itching, and even tearing off the dress-
ings in order to get at the skin. Ichthyol, in twenty-five
to fifty per cent, solution, will sometimes afford the
greatest relief in this condition, the hands being kept
painted with it all the time.
Patches of eczema on the backs of the hands and
fingers will commonly yield to the Lassar salicylicated
ointment just mentioned (p. 35), if it is kept on a suffi-
cient portion of the time. It is here that the use of thin
layers of absorbent cotton, spread with the ointment and
bound on lightly with thread, serves the best purpose.
Sometimes, in thickened patches, we can best reach the
trouble by frictions with the compoimd tincture of
green soap (Formula 18, p. 41), rubbed well on with
a bit of flannel, followed by a proper ointment.
In very thickened chronic patches I have used, with
the best results, a lotion containing two or three per
cent, of caustic potash, in water, immediately followed
by the diachylon ointment of Ilebra (Formula 5, p. 33).
In eczema of the palms the diachylon ointment of
TEEATMEXT IN DISEASES OP THE SKIN 77
Ilebra often accomplishes more than any other applica-
tion ; three to ten per cent, of salicylic acid may be
added with advantage in very chronic cases. The X-ray
is sometimes most valuable in removing this condition.
Eczema of the feet and legs has some features which
are worthy of special attention, in regard to local
treatment.
First, it is to be remembered that the retarded circu-
lation, owing to the dependent position of the parts,
has much to do with the occurrence and obstinacy of
the eruption in this location. It is well, therefore, in
severe or obstinate cases, to have the affected part ele-
vated as much of the time as possible, and that not sim-
ply on a stool or chair, but even higher than the head,
that the blood pressure may be relieved ; this is accom-
plished by lying down, or leaning far back in a rocking
chair, and placing the feet at as great an elevation as
possible above the head. At night this object may be
attained by elevating the foot of the bedstead with some
bricks or books on the floor ; and at this present moment
you could probably see one or more beds thus arranged
in the wards of this hospital, holding patients with
severe eczema or varicose ulcers of the legs.
In the solid rubber bandage, however, we have a most
valuable means of overcoming the circulatory deficiency
often existing in the lower extremities, and of this you
have seen repeated illustrations in many of the cases
presented in the clinic during the past year. But I
deem this such a priceless measure in some cases that,
at the risk of being a little tiresome, I will now apply
such a bandage to a patient and speak a little fully in
78 PEINCIPLES AND APPLICATION OF LOCAL
regard to the matter; for, after an experience with it
of nearly thirty years* I find that there are some minor
details relating to its employment which are of the
greatest importance, but which are not universally un-
derstood or carried out.
The bandage should be very thin, three inches wide
and about five yards long: I have discarded the tapes
which I formerly had attached to one end, as I find it
better to pin it, as an ordinary bandage.
Even for a localized trouble it is best to apply it from
the toes to the knee, lapping it about one-third of its
width; it should never be reversed, and with a little
coaxing it can be perfectly applied without even exerting
too much pressure anywhere, leaving the heel free. Care
should be exercised to have it perfectly comfortable,
and I have patients walk around with it, and wait a
while in my presence; when rightly applied they will
often at once express the greatest satisfaction in the
relief to the previous tense, distended feeling of the
limb. If at any time it is uncomfortable it should be
taken off and readjusted.
The bandage is removed at night, and I commonly
direct that this shall be done after the patient is entirely
undressed and in bed, and that the foot shall not be put
down again until after the bandage has been correctly
reapplied in the morning, while still in bed. On re-
moving the bandage it is dropped into a basin of water
and left there while the leg is dressed for the night : it
is thnn washed and dried, by drawing it through a
towel, and then festooned on the back of a chair, to air

TREATMENT IN DISEASES OF THE SKIN 79
until morning, when it is rolled and applied as before.
When the bandage is taken off at night, the leg is gen-
erally pretty wet with the confined perspiration ; this is
to be lightly wiped off with a cloth dampened with water,
in which there is, perhaps, a little soda and carbolic
acid, and the proper dressing is applied, and the limb
lightly done up for the night. Sometimes there are a
few pustules on healthy parts, caused by the bandage,
but these soon dry up and cease to be produced.
In putting on the bandage in the morning, care must
be exercised that no grease from an ointment is left on
the parts, as it readily destroys the elasticity of the
bandage. But in removing the night dressings, before
reapplying it, undue irritation of diseased surfaces
must be avoided ; if they adhere, the dressings must not
be roughly torn off, but softened, if need be, with oil, or
peroxide of hydrogen, and any surplus ointment re-
moved by gentle wiping with cotton, or moderate scrap-
ing with a dull knife. It is well then to lay an exceed-
ingly thin layer of absorbent cotton over such a part,
indeed over any sore or raw surface, before applying
the rubber bandage. There is no such trouble on remov-
ing it at night, for the entire surface is moist.
This solid rubber bandage is not only valuable for
varicose veins and ulceration of the leg, but, as you
have seen in the clinic, is most serviceable in many
cases of chronic eczema in this region, whether attended
with varicose veins or not. I have indeed applied it,
with the most satisfactory results, to cases which might
be called sub-acute, and where the propriety of its
application might be at first questioned. But in my
80 PEINCIPLES AND APPLICATION OF LOCAL
long use of it, in many, perhaps hundreds of cases, I
cannot recall an instance where it did not do good work,
if I could get the patient to rightly grasp the idea and
to properly carry out the technique. On the other hand,
words would fail to convey to you the expressions of
satisfaction and thankfulness w^hich I have had from
patients in private and public practice, for the relief
and benefit w^hich they had received from the proper
use of a rubber bandage. ISTor is it a difficult or trouble-
some matter for patients to learn to use it properly;
even the most ignorant of those in hospital practice
soon learn to carry out all details minutely, if only a
little thought and patience is given to instruct them cor-
rectly, often more than once. And when once they have
experienced the benefit of it they are very assiduous
in its use until cured.
At the risk of further wearying you I must point
out some of the advantages of the solid rubber bandages
over the other means sometimes employed in its place,
such as cotton, flannel, gauze, or even elastic webbing
bandages, and the laced, or even the elastic stocking.
There is no comparison between the agreeable elas-
ticity of the solid rubber bandage and the more or less
stiff, non-yielding character of all the others. As com-
pared even with the elastic stocking, this bandage has
great advantages, as many patients will testify. The
stocking is necessarily of a fixed size, often too tight
when the leg is swollen and too loose as the swelling goes
do^^^l, and so may not afford adequate support ; whereas
the rubber bandage is adjusted to the daily condition of
the limb, and by its steady, graduated compression
TEEATMENT IN DISEASES OF THE SKIN 81
maintains the requisite support and induces absorption
of diseased products.
The woven elastic webbing bandage cannot compare
with the solid rubber, as I have repeatedly observed.
The rubber bandage does not adhere, and comes off
without doing violence, even to a raw surface, as you
have seen demonstrated in the clinic. It does retain
the secretions, and sometimes these will ooze between
its folds, but no harm is done, and the gentle cleansing
of the part on removing, with the appropriate dressing
for the night, tends to continually heal the affected
parts.
One word in regard to the rationale of its action.
As all know, the circulation depends for its move-
ments upon heart action, and the return of the blood
by the capillaries and veins is the result of this vis a
tergo, assisted by a measure of contractibility in the
vessels, and aided somewhat by the action of the volun-
tary muscles in various locations, in varying degrees.
There is, of course, a constant tension in the blood ves-
sels, large and small, which in the lower extremities is
increased greatly by gravitation. We all know how the
capillaries and veins lose their elasticity and become
distended, and how difficult it is to overcome this so-
called varicose dilation, which prevents proper nutrition
and the absorption of diseased products.
After employing the solid rubber bandage for nearly
thirty years, in hundreds of cases, in private and public
practice, I am more and more convinced of its supreme
value in a large class of cases often most obstinate under
other treatment. By virtue of its elasticity it acts as a
82 PRINCIPLES AND APPLICATION OF LOCAL
supplementary aid to the circulation, with every muscu-
lar movement of the limb ; hence it is desirable to have
patients walk as much as possible, short of fatigue. In
this way I have seen long-standing eczema and ulcera-
tion of the leg get well in a remarkably short time.
There is rarely if ever any itching while the bandage
is on.
The local applications required in the treatment of
eczema of the lower extremities do not differ essentially
from those employed elsewhere. When the solid rubber
bandage is used I am very apt to order, at night, a cala-
mine and zinc lotion (Formula 3, p. 30) to be freely
sopped over the affected part twice, at ten-minute in-
tervals, so as to leave a good coating on the diseased sur-
face, which is then covered with an extremely thin layer
of absorbent cotton, and bound rather lightly with a
gauze bandage. Many ointments serve a good purpose
at night, such as salicyicated Lassar's paste (Fonuula
11, p. 35), or the diachylon ointment of Hebra (For-
mula 5, p. 33), or, if there is much itching, the tar and
zine ointment (Formula 14, p. 37), if properly ap-
plied, gives relief, or even the "skin food'' (Formula
15, p. 33) with menthol.
Eczema of the anus and geniial region. Before
giving you some practical suggestions as to the local
treatment of eczema in this locality, I must remind you
of what I said in my special lectures last year ; namely,
that proper internal treatment, dietary, hygienic, and
medicinal, is of the greatest importance here, and that
local measures are often relatively ineffective alone.
But proper local treatment is most essential, and one
TREATMENT IN DISEASES OF THE SKIN 83
constantly sees far more harm than good done by inju-
dicious applications which have been made, in the
endeavor to control the maddening itching which some-
times occurs, and recurs, chiefly at night. Patients will
often plead for stronger and stronger remedies until
the parts have been brought to a lamentable state of
inflammation. Much of what is thought to be eczema
of the anus is pruritus alone, of neurotic origin — also
often most difficult to cure — to which eczema may be
added by scratching and unwise treatment.
In eczema of the anus benefit can often be obtained
by the right use of hot water: the water should be as
hot as can possibly be borne, and applied exactly as
follows: A handkerchief is dipped in the water and
held to the part for a short time, a minute or less, and
then w^et again and reapplied, two or three times in all,
perhaps not more than two or three minutes altogether :
tepid water, too long bathing, or too frequent sopping,
etc., may aggravate the trouble. The part is then dried
by holding a hot cloth to it, and the proper remedy
is instantly applied on its removal. Ordinarily it is
best to use the hot water only once in the twenty-four
hours, after undressing, and when quite ready to get
into bed. The patient must manage not to scratch before
applying the hot water, and if the process is well done,
and a suitable application made immediately, the relief
may last long.
In milder cases a cooling lotion (Formulae 3, 4, p. 30),
thoroughly sopped on, instantly after the hot water, fol-
lowed by a second application of it alone in ten minutes,
will be all that is required. The lotion can be reapplied
84 PRINCIPLES AND APPLICATION OF LOCAL
later, if there is itching, or a bit of handkerchief wet
with it and tucked in often gives relief. It is often
desirable to add the lotio nigra to such a lotion:

xri. ft. Lotio.
In some cases a mild ointment (Formulae 6, 7, pp. 33,
34) is more agreeable. This should not be rubbed on the
part, but be spread thickly on the woolly side of a bit
of lint, cut to fit the part, or, better yet, on a thin layer
of absorbent cotton: all applications should be fully
ready before the use of the hot water, so that they can
be laid on instantly on removing the hot, drying cloths.
When a more anti-pruritic action is desired the oint-
ment of tar and zinc (Formula 14, p. 37), or one with
ichthyol, oil of cade, or oleum rusci, half a drachm to
one drachm in the ounce, is effective, applied in the
same manner : a drachm or two of belladonna ointment,
or tincture of aconite (Formula 17, p. 39), may be
added with advantage, as also cocaine.

Eczema of the scrotum, when mild, will often be
most satisfactorily treated by such a lotion as the cala-
mine and zinc (Formula 3, p. 30), or that with mag-
nesia (Formula 4, p. 30), freely sopped on and repeated
often enough to keep a coating of the sediment found in
them on the parts. When the eruption is more severe,
and especially when there has developed much thicken-
ing of the skin, the best results are obtained by the use
of very hot water, applied as previously directed, and
followed especially by the tar and zinc ointment (For-
mula 14, p. 37). The ointment should not be rubbed
on the part, but spread on the woolly side of lint,
adapted snugly and kept in place by a well-fitting sus-
pensory bandage.
Eczema of the female genitals is sometimes most re-
bellious imless just the right applications are used in a
correct manner. It must be remembered, however, that
it is often dependent upon irritating vaginal discharges
which must be checked before great benefit can be
secured by local treatment. jMy constant treatment for
this is carbolic acid, half a drachm to a drachm, with
from two to four drachms of borax, or chlorate of
potash, to the pint of water, as hot as can be borne : this
I have thrown in forcibly with a Davison's syringe
(and not from a fountain syringe) night and morning.
The local treatment is much as has been described.
86 PEINCIPLES AND APPLICATION OF LOCAL
The greatest relief is often obtained in milder cases by
the free use of one of the lotions just mentioned (For-
mulae 3, 4, p. 30), which may often be best applied by
means of a bit of handkerchief thoroughly wet with it
and tucked deeply in. Very hot water, used as already
directed, is of the greatest service, followed by a lotion
or the ointments previously mentioned, applied in the
same manner. In many cases a very mild ointment of
calamine and zinc (Formula 6, p. 33) is most effec-
tual; menthol may be added with advantage, two per
cent. When there is considerable itching, without much
raw surface, a chloral and camphor ointment (Formula
16, p. 38) gives great relief, although it sometimes
proves very irritating, and must be used very weak.
Ichthyol in watery solution, twenty-five to fifty per
cent., also a watery solution of permanganate of potas-
sium, two to four per cent., are effective.
Eczema of the crotch will sometimes be parasitic,
manifesting a sharp outline, and rather clearing within,
eczema marginatum. This will not yield to the meas-
ures described, but must be treated with a view to
destroy the parasite ; this, however, should be done with
care, and often it is necessary to use proper eczema
treatment conjointly or alternately.
The remedy which I most prefer is the strong, undi-
luted sulphurous acid, and although this may smart
considerably at first, it will arrest the itching and check
the disease admirably. To be effective it should be
fresh, for when exposed to the air the sulphurous acid
H^SOg becomes changed into sulphuric acid H^SO^,
which is very irritating and not efficient as a parasiti-
TEEATMENT IN DISEASES OF THE SKIN 87
cide. For this reason I always have the patient purchase
an original, unopened package of a pint, and from this
fill a smaller bottle, keeping the other tightly corked.
The acid is applied by means of a bit of cloth soaked in
it, which is held to the part a while, one or two fresh
applications being made to insure the penetration of
the remedy. After a few moments of drying, the sur-
face is sopped with a soothing lotion, or a proper oint-
ment (Formula 6, p. 33) is applied, spread on lint.
The acid should be applied night and morning, unless
there is too much irritation. Other parasiticides may
be employed, as mild mercurial, sulphur, or beta-naph-
thol ointments
32. I^ Beta-naphthol 3i-3ii
Ung. lanolin comp. (formula 15, p. 37) ... 5i
nx. ft. Unguent.
but great care must be exercised not to over-stimulate
this part, where the skin is very tender.
Eczema of the trunk and general eczema present some
features in regard to local treatment which it may be
well to mention.
Beneath the breasts, and in the fold of the pendulous
abdomen, as also in the groins, powders are frequently
used in the hope of drying up the eruption ; but these are
often found to be made into a paste by the moisture, and
the parts are greatly irritated. If any of the powders
are used they must be applied very freely, in quantity
to effect the desired result, and it is well in addition to
keep a fold of handkerchief between the parts, well
dusted on both sides; the old-fashioned home method
88 PEINCIPLES AND APPLICATION OF LOCAL
of scorching the handkerchief first seems to aid in the
result desired.
The following combinations are of service :

In milder cases the soothing lotions (Formulae 3, 4,
p. 30), with perhaps first bathing with a ten to twenty-
five per cent, watery solution of ichthyol, give excellent
results. ^Yhen ointments are used they should be
thickly spread on the woolly side of lint and kept firmly
bound in place with a gauze bandage.
In the axillce ointments can often be best applied when
spread on thin layers of absorbent cotton, which are
well pressed into the cavity and held properly in place.
For the abscesses often occurring in this region an ergot
ointment is most valuable, and is all that is required,
from first to last: and this is much preferable to poul-
ticing.

TEEATMENT IX DISEASES OF THE SKIN 89
You will remember that I have frequently said that
ointments should, as a rule, not be rubbed on or into
the skin, in eczema, except in very chronic patches, but
there is one form of eruption, formerly known as sebor-
rhoica eczema, now called dermatitis seborrhoica, in
which the application must be rubbed in, in order to
obtain eflPective results. As seen on the chest and back
it will often yield in a surprisingly short time to the
thorough application of a resorcin ointment, such as the
following :

Zinci oxidi 5ss
Unguent i aquae rosse 5i
n\. ft. Unguent.
When rebellious, sulphur may be added to this with
advantage (Formula 23, p. 44).
I will close this lecture with some remarks in regard
to washing and bathing in eczema. I have several times
mentioned the harm that often comes from the too free
use of water and soap in this eruption, and you cannot
be too careful in seeing that this is done only when
directed, and in the proper manner. In some instances,
when there is a mass of crusts, or incrustations from old
dressings, the free use of soap and water for a single
time may be desirable. But as so often practiced by the
uninstructed laity, frequently and severely, only harm
can result. I think that some of you would be surprised
if you could hear my constant instructions to patients
on this subject : in some cases of infantile eczema I
have kept soap and water from the skin, except in cer-
00 PEINCIPLE8 AND APPLICATION OP LOCAL
tain regions, for days or even weeks, and with only the
best results.
Also in eczema in adults, where an inflamed and irri-
tated skin is trying to form a healthy epidermal cover-
ing, the free use of soap and water only retards the
progress, as is seen strikingly in the case of washer-
women: but even in these latter you have seen in the
clinic that the harm done can be in a measure neutral-
ized if exactly the right local application is made imme-
diately when the hands are dried, and if it is kept on
as much of the time as is possible.
If I am asked as to what soap is good for eczema, I
have to answer that, as far as I have observed, there is
none. I have no confidence whatever in the many adver-
tised medicated soaps, and have failed to see benefits
from their use which could not be ascribed to other
treatment used conjointly. I might make an exception
to tar soap, which can, perhaps, be sometimes used
with the least prejudicial results. But do not be led
away with the alluring advertisements of regular or
irregular business houses into the idea that any special
or medicated soap can cure eczema ; the eczematous skin
is better without much or any soap.

Gentlemen :
In the last lecture we began the application of the
principles of local treatment to special cutaneous affec-
tions. I took eczema first, both because it is by far the
most frequent disease of the skin, and because the prin-
ciples and methods of its local treatment are widely
applicable to many other cutaneous conditions.
In treating of eczema, I commenced with infantile
eczema, in order to impress upon you the delicate struc-
ture of the skin, and the necessity of fully realizing this
fact in connection with many congestive or inflamma-
tory cutaneous affections.
Psoriasis. To-day I turn at once to quite another
eruption, namely, psoriasis, which often, in chronic
cases, manifests exactly the opposite condition of the
skin, namely, a resistance to irritation which is some-
times remarkable. But I have to caution you that this
is not always so; for in acute and recently developing
cases there is congestion of the skin, which quite contra-
indicates stimulating measures, and the eruption may
then yield to mild remedies ; while, on the other hand,
91
92 PKINCIPLES AND APPLICATION OF LOCAL
even in chronic cases active treatment, as by chryso-
phanic acid, may light up an irritation requiring quite
other remedies.
Psoriasis undoubtedly is one of the most stubborn
of all cutaneous diseases, and will tax the patience of
physician and patient to the utmost. But I do not hold
psoriasis to be incurable; although it certainly is not
curable by local treatment alone. The eruption can
often be temporarily removed in a surprising manner
by external measures, but it is very sure to return,
except under the most rigid and continuously prolonged
treatment, dietary, hygienic, and medicinal, which can-
not be detailed here ; we have now to do only with local
measures which offer the best prospects of temporary
benefit.
The X-ray is one of the most striking of these in cer-
tain cases; when used rightly, a few applications may
often cause old patches of the eruption to fade away,
almost as if by magic, often leaving, however, a pig-
mentation which may be a little slow in disappearing.
But it is by no means suitable to all cases, and I can
hardly be too emphatic in protesting against the indis-
criminate use, and even the abuse, of this agent which
is sometimes practiced. It is entirely unsuitable to
very generalized cases, and to those which are acute or
exhibit congestion of the surface ; indeed it is to be em-
ployed rarely, and only to remove chronic patches which
resist other treatment. The danger of a burn from it
should always be borne in mind.
Chrysophanic acid, or chrysarobin, is another means,
the results of the right application of which are fre-
TEEATMENT IN DISEASES OF THE SKIN 93
quently surprising, although occasionally it fails to
accomplish its object and only irritates the skin un-
necessarily. You all know the drawbacks to the use of
chrysarobin, and that it stains the skin, hair, and linen
dreadfully, and sometimes excites very disagreeable
inflammation ; so that one tries to avoid its use in pri-
vate practice. When the patient will stand it, and is in
haste to have the existing eruption removed, there is
hardly any external application which will generally
accomplish the purpose more quickly in suitable cases
and in the proper strength.
But all cases are not suitable, and skins differ in the
amount of its stimulation which they will stand. When
the eruption is developing, or when the surface is hot
and congested, chrysarobin may only increase the diffi-
culty and aggravate the eruption. It is well always to
begin with a mild strength of ointment, fifteen or
twenty grains to the ounce, and increase it as seems
proper; in some instances it can be used even up to a
drachm to the ounce.
Some substances modify or heighten the action of
chrysarobin, and in this hospital we have long used the
following combination w4th excellent results:

The oleum rusci seems to modify the irritating re-

heightens its beneficial effects, and the green soap aids
their penetration.
Pyrogallic acid, thirty to sixty grains to the ounce
of ointment, is of more or less value in psoriasis, but
inferior to some of the other remedies in use; salicylic
acid is also very ser\'iceable, and may well be added to
many applications.

Ammoniated mercury, white precipitate, is also a
remedy of the greatest value in psoriasis, and often
suffices to remove the eruption from many localities.
I very commonly at first use the pharmacopoeial oint-
ment diluted four times, making it of the strength of
twelve grains to the ounce, and always add one or two
per cent, of carbolic acid, increasing the amount of the
mercurial ointment as occasion requires ; bismuth seems
to aid the action of the mercury.

Beta-naphthol, from half a drachm to a drachm to
the ounce of albolene ointment, is also verv often an
eflScient remedy in psoriasis, and has the advantage of
being cleanly. To be of service it should be well rubbed
into the patches, even with a rather stiff stencil brush.
Chrysarobin, salicylic acid, and pyrogallic acid are
also often used advantageously, alone or combined, in
a strength of from five to ten per cent., in flexible col-
lodion, or liquid gutta-percha, to paint on isolated
patches ; but their effect in this form is not equal to that
obtained when used in ointment : there is, however, the
great advantage of not staining the linen. When ap-
plied the surface should be free from scales, and it is
necessary to frequently peel off the old application
before making it again. They may also be used in a
gelanthum paint, being added to it in a strength of from
five to ten per cent.
But, as I stated at the outset, all cases of psoriasis
are not to be treated in a severe manner. In newly
developing cases, with proper internal measures, it is
often surprising how the eruption, when developing,
may disappear under the free and repeated application
of so simple a remedy as the calamine and zinc lotion,
or that of magnesia and zinc, already mentioned
(Formulae 3, 4, p. 30).
A good deal of psoriasis is accompanied by dermatitis
96 PRINCIPLES AND APPLICATION OF LOCAL
sehorrhoica, and, indeed, some cases which might be
called psoriasis are only exaggerated forms of the latter
eruption. The value of resorcin, therefore, should never
be forgotten in psoriasis, and I am confident that many
cases do far better when there is constant attention to
the scalp, with the application, morning and night, of
the resorcin lotion, mentioned in the last lecture (For-
mula 22, p. 44). Also, on the face and on other parts
of the body, an ointment or resorcin and sulphur,
of each twenty or thirty grains to the ounce, will some-
times work wonders on what is apparently psoriasis,
and even affect the real disease favorably.
As the object in such an eruption as psoriasis is to
obtain penetration of the medicament, vaseline or the
solid albolene, perhaps with a little lanolin, are the
most useful substances for ointments ; it is sometimes
desirable to cover it with an impermeable dressing, as
waxed paper.
Alkaline baths are often of much service in psoriasis,
and may be given quite frequently, even several times
a week, the appropriate application being made imme-
diately afterward.

Having now spoken of the eruption which often re-

ment, psoriasis, I wish to briefly consider some others,
perhaps in an ascending scale as regards susceptibility
to stimulating treatiueut : for in the short time at our
disposal I cannot, of course, compass all diseases of the
skin. I am endeavoring, however, to have you under-
stand the principles of local treatment, that you may
the better apply them to any eruption which you may
meet.
Lichen Planus, once called by Jonathan Hutchinson,
of London, lichen psoriasis, is an eruption which ex-
hibits phases to which all that has thus far been said
may apply. In its earlier, acute, developing stage it
calls for most soothing treatment, to allay the occa-
sionally great irritation and itching present ; while
more chronic lesions, in localized patches, wall some-
times resist, and finally yield only to a highly stimu-
lating local treatment, including hyper-static electricity
and the X-ray. ^Mention was made in Chapter II, of an
absorbent ointment (Formula 21, p. 43) which is often
of great value in isolated chronic patches of the erup-
tion. But in the congestive, developing stage all these
strong measures only aggravate the eruption, and such
things as the calamine and zinc lotion and the like are
not only highly acceptable, but very beneficial, and
the eruption may disappear under them.
Erythema Multiforme, in its papular form, may bear,
and sometimes does require, applications of rather a
stimulating character; but if these are applied to its
more acute manifestations, especially when there is a
tendency to the formation of bullae, only the direst
results will follow.
98 PEINCIPLES AND APPLICATION OF LOCAL
Urticaria. Here we come to an eruption which is both
acute, as far as its lesions go, and also frequently
chronic in regard to its continued manifestations. All
harsh treatment is only calculated to do harm and to
still further excite the already erythrytic skin. But
one continually sees mistakes made in attempting to
relieve the itching, which is at times intolerable: and
what with the often frantic efforts of the patient in
rubbing and scratching, even with brushes, etc., and
the almost as frantic efforts of the physician to give re-
lief by various applications, the skin is sometimes re-
duced to a pitiable condition.
The calamine and zinc lotion, so often mentioned, or
the like, with an extra amount of carbolic acid, will
often prove quite enough to give relief, with suitable
dietetic and medicinal treatment. When this is not
wholly agreeable, a powder in which chloral and cam-
phor, of each a drachm to the ounce has been rubbed
up, will often be most grateful.

When the skin is more dry and an ointment is called
for, one containing two to four per cent, of carbolic acid,
in what I described as *'skin food" (p. 37), is very satis-
factory, or sometimes it may be used in the glycerite of
starch: menthol, two to six per cent., heightens the
effect ; this is gently applied with the palm, several times
daily.

Camphor and chloral, in ointments, as mentioned in
an earlier lecture, will likewise give great relief. Alka-
line baths are also serviceable (Fornmla 41, p. 96).
Pruritus. This is another cutaneous condition where
local therapeutic measures are often abused. I refer to
simple pruritus as a disease, where there is only itching
on the skin, without visible lesions except those that
have been produced in the efforts to get relief. The
measures just mentioned in connection with urticaria
are those which, with appropriate general treatment,
are most likely to give relief ; but if any very strong ap-
plications are made they only irritate the surface and
fail to reach and allay the excited nerves. For, it must
be remembered, that the seat of itching is generally
deep in the skin, far below the epidermal outer layer
upon which we make our applications.
Localized pruritus, especially that of the anal and
genital region, will often prove most seriously rebellious
and almost defy relief. Carbolic is here one of the
most efficient remedies, and may be used in watery
solution, with a little glycerine, or in oily solution, two
to five per cent. The tarry ointment already mentioned
(Formula 14, p. 37), made a little stronger, if neces-
sary, or with the addition of half a drachm or a drachm
of ichthyol or oleum rusci to the ounce, very commonly
100 PEINCIPLES AND APPLICATION OF LOCAL
gives relief, if continuously and rightly applied. Here
it is often very desirable to spread it on thin layers of
cotton, as already described. This is especially service-
able after the application of very hot water, in the man-
ner detailed a while ago. In very stubborn cases the
addition of cocaine, one to four per cent., as also extract
of belladonna, and aconite, may be required (Formula
17, p. 39) ; w^ith these latter care must be taken that
there is not too much absorption, with constitutional
effects.
Electricity, both the static and hyperstatic, and also
the galvanic current, is sometimes of great value in
controlling pruritus ; the X-ray has also been favorably
reported on, but in using this about the anal or genital
region the danger of producing sterility should always
be considered.
We will now consider quite another class of cutane-
ous affections, those associated with the production of
pus, and will speak of some practical matters in con-
nection with the local treatment of acne, boils, and
carbuncles.
Acne has been already mentioned (page 56), in regard
to its personal manipulative treatment which latter can
often effect so much, and which should never be omit-
ted when called for. The local applications made in
acne have a three-fold object, namely, soothing and
allaying inflammation, astringing and giving tone to
the weakened skin and its glands, and overcoming mi-
crococcic influence.
In the more inflamed cases, botli of aeno simplex and
rosacea, the calamine and zinc lotion, repeatedly men-
TREATMENT IN DISEASES OF THE SKIN 101
tioned, will often prove most satisfactory for a while.
In the general run of cases the lotion now occasionally
known as lotio alba, which I brought to the attention of
the profession many years ago, will give excellent re-
sults if used rightly.

If this proves too drying to the skin it may be softened
by the addition of half a drachm or even a drachm of
glycerine in the four ounces. When a more astringent
effect is required the amount of the solid ingredients
may be increased, or even doubled, and often it is made
more effective by the addition of half a drachm, or a
drachm, of precipitated sulphur in the four ounces.
When single lesions are more rebellious a lotion of
sulphur and ether is very effective.

In instances where either of these lotions have pro-
duced too much drying and scaling of the surface, this
may be easily remedied by the free use of a softening
lotion, such as the following:

102 PKINCIPLES AND APPLICATION OF LOCAL
This is applied by means of the palms of the hands,
rubbing the face, with some self-massage.
Ointments are not often necessary in acne, but some-
times one of resorcin and sulphur, of each twenty to
thirty grains in the ounce, will assist materially in
absorbing large lesions : occasionally resorcin is used in
much greater strength, even up to ten, twenty or more
per cent., applied until it produces some exfoliation;
but this harsh treatment I have but rarely used.
The mode of making applications and the general
treatment of the face has much to do with success in
the treatment of acne. I commonly direct that the
lotion be shaken, and some of it poured out in a small
covered dish, like the old-fashioned china ointment-
box, in which a small bit of linen handkerchief is kept.
With this the lotion is freely sopped on the eruption,
when first beginning to undress for the night: in ten
or fifteen minutes (without washing) a second applica-
tion is made, so as to form quite a coating of the sedi-
ment in the lotion, for the night. In the morning the
face is washed with cold water, and without soap, using
the hands, as, I say, a man washes his face, and with
some friction and self-massage. Immediately after
drying with a soft towel, a single application of the
proper lotion is made in the manner described. On
leaving the room, if desired, any superfluity of the
adhering sediment left by the lotion may be removed
with a handkerchief, dampened with water; but the
face should not be washed, but left under the influence
of the lotion as much of the twenty-four hours as possi-
ble. If it should require washing during the day, this
TREATMENT IN DISEASES OF THE SKIN 103
should always be done with cold water, and the lotion
may be applied to the affected parts.
When there are single lesions which resist this treat-
ment we can get a much more active effect from the
lotion by saturating very small bits of absorbent cotton
with it, and laying them on each spot; when put on thus
at night, these small bits of cotton wull often remain
adherent until morning, thus keeping the lesion con-
stantly soaked with the lotion.
I do not advocate the use of the X-ray in acne, but
in certain cases where hard, indolent masses resist other
treatment, I have seen the X-ray cause them to be
absorbed in a surprising manner.
Boils. For many years I have not allowed boils to be
poulticed, when I could prevent it, as I believe that
they can be treated far better otherwise ; and I believe
also that poultices tend only to increase unnecessarily
the amount of suppuration and further the development
of new boils ; nor do I incise either boils or carbuncles,
except under unusual circumstances.
Some years ago I wrote fully in regard to the non-
surgical treatment of boils and carbuncles,* and have
found no necessity of changing my views then ex-
pressed. I must, however, insist that the entire plan
of treatment there outlined, constitutional and local,
be followed, and not the latter alone, as I find .is too
often the case, by physicians who have communicated
with me on the subject. The local measures only can
be here mentioned.
* Bulkley: Notes on the Non-surgical Treatment of Boils, Car-
buncles, and Felons. British Medical Journal, Oct. 2, 1897.
104 PKINCIPLES AND APPLICATION OF LOCAL
The objects aimed at by the treatment are: 1. Pro-
tecting and soothing an inflamed area; 2. Exclusion of
air; and, 3. A slightly antiseptic and astringent dress-
ing. For this purpose a moderately thick layer of ab-
sorbent cotton is taken, several times the size of the
inflamed area; for a medium-sized boil a piece one by
two inches, with the fibers running the long way. Upon
the center of the cotton a considerable mass of the fol-
lowing ointment is spread by means of a table knife,
and this is then laid on the boil and held in place by
strips of zinc plaster placed across the ends, and not
passing over the boil, as commonly practiced. The
ointment referred to is generally composed about as
follows :
46. I^ Acidi carbolici gr v-x
Extr. ergot 86 fid 3i
Pulv. amyli 3i
Zinci oxidi 3ss
Unguenti aquae rosae. . . 5i
xry. ft. Unguent.
The relief given by this dressing is very marked ; the
ointment protects and soothes the irritated surface,
while the layers of cotton take up the outside friction.
If comfortable, and unless disturbed, this dressing re-
mains untouched for twelve or more hours, when it is
removed and a freshly-spread piec« is immediately re-
applied. If there has been any discharge, the surface
may be very gently cleansed with absorbent cotton, but
I do not allow any squeezing. With proper internal
and general treatment the boil frequently aborts and
subsides without discharging; when this does not hap-
TEEATMENT IN DISEASES OF THE SKIN 105
pen it ruptures spontaneously in a relatively short
time, and I practically never find it necessary to in-
cise it.
This treatment I use in all stages of furuncles, keep-
ing the ointment on until the surface is quite healed.
If other boils form I direct the ointment to be applied
early, and by this means they are frequently aborted.
I wish I could adequately express to you the comfort
and pleasure given to patients, when thus dressed, as
compared with the sensations and results from other
treatment which they had previously undergone under
other hands.
The ointment may sometimes be modified for indi-
vidual cases, and sometimes an ichthyol ointment serves
very well; but for more than twenty-five years I have
followed the plan indicated, with, of course, the thor-
ough internal and general treatment, and many patients
have returned for subsequent treatment of boils, with
strong expressions of satisfaction with this method, and
of preference over any other, both in point of comfort
and duration of the trouble.
Carbuncles. As a carbuncle is in reality but a large
boil, or a conglomeration of boils (with certain ana-
tomical differences), the general and local treatment of
carbuncles, with me, has been much the same as just
described. Both early and late in the disease I have
put on an ointment like the above, and fastened it at
the ends with strips of adhesive plaster, never passing
them over the inflamed surface. Not only on the back
of the neck, but also on the face and elsewhere, this
dressing proves most comforting and serviceable, and
106 PRINCIPLES AND APPLICATION OF LOCAL
I have not had occasion to incise a carbuncle since
November, 1882, nearly twenty-five years ago.
This treatment has been applied, under my directions,
to some large and formidable carbuncles, and I have
always, thus far, found that the pus would find exit
rapidly enough, and the healing process take place sat-
isfactorily with this dressing. Occasionally it is neces-
sary to aid the expulsion of pus by very slight squeezing,
or by the removal of sloughs with the forceps. On some
occasions febrile and other symptoms have seemed to
call for more active interference, as with the knife ; but
although urged to it, when in consultation, I have ad-
hered to this plan of treatment, without incision, and
have obtained results which warrant its continued em-
ployment. From my previous experience with cutting,
and from observing cases thus treated by others, I be-
lieve that the method now recommended has the prefer-
ence, both as to time occupied and the final results;
w^hereas, on the point of pain and general comfort of
the patient it is far superior, when carried out with all
possible details necessary as to general and constitu-
tional management.
I am quite prepared to admit, however, that possibly
from neglect or other cause, a very large, suppurative,
carbunculous area might be formed which would de-
mand very active surgical procedure, such as curetting
or even excision, with antiseptic dressing; but under
the treatment described this has never occurred. I max
mention that Sir James Paget, in his '"Clinical Lec-
tures and Essays," discountenances strongly the prac-
tice of incision; and I may also add that since I first
TEEATMENT IX DISEASES OF THE SKIN 107
publicly advocated this plan of treatment in boils and
carbuncles, almost twenty years ago, I have had con-
tinuation of its value from dozens of practicing physi-
cians, verbally and by letter.
Parasitic diseases. There is quite another class of
cutaneous atfections to be now considered, where an
entirely ditferent aim or object exists as to local treat-
ment, namely, the parasitic diseases of the skin, animal
and vegetable.
While some of the already mentioned principles of
local treatment may at times be required in combatting
parasitic diseases, our main purpose here is to destroy
the foreign elements which have produced the erup-
tion in question, and yet not to destroy or injure
the delicate skin affected by them; and sometimes
this is a difficult task. To accomplish this many
different remedies may be used. I will first speak
of the two main animal parasitic affections, scabies
and pediculosis.
Scabies. Sulphur, as is well knowTi, will cure scabies ;
that is, if used properly it will destroy the life of the
scabies insect ; but it may often inflame the skin, if used
in the strength recommended in the Pharmacopoeia,
nearly three drachms to the ounce ; a drachm or two to
the ounce is quite sufficient.
There are, however, other substances which destroy
the aearus of scabies, and beta-naphthol, half a drachm
or a drachm to the ounce of ointment, is very efficient,
and has the advantage of being cleanly. Storax, a
drachm to the ounce, is also serviceable. Often it is
best to combine several ingredients in one ointment,
108 PEIXCIPLES AXD APPLICATION OF LOCAL
and in this hospital we generally use what we call un-
guentum contra scabiem, composed about as follows :
47. I^ Sulphuris precip 3uss
Pulv. cretae prep 3ii
Zinci oxidi 3i
Styrax 3ii
Unguenti picis 3ii
Saponis viridis 3ii
Adipis 5x
tT\. ft. Unguent.
This rather shotgun prescription serves many pur-
poses, and answers very well in the average run of cases.
The sulphur and the storax are the active anti-parasitical
elements, and the chalk and green soap are thought to
help break open the furrows where the insect is hidden,
while the zinc and tar ointment aid in allaying any
undue irritation.
But the secret of the cure of scabies is the thorough-
ness of application, and I will briefly mention the
method employed in the celebrated Hopital St. Louis,
in Paris, which we more or less follow here. The pa-
tient first soaks in a warm bath; the entire surface is
then thoroughly anointed with green soap, which is very
well rubbed in, especially over the places most infested
by the parasite, hands and arms, front folds of the
axillae, abdomen, etc. The patient then enters the bath
again for a quarter of an hour, and after drying has
the ointment very thoroughly rubbed in, for a long
time, even half an hour. The same underclothes are
put on, and the ointment freely rubbed in, night and
morning, with no bathing till the third day, when, after
a bath, the skin mav be left untreated, to see if the
TEEATMENT IN DISEASES OF THE SKIN 109
cure has been complete. If there are still lesions or
much itching, the process should be repeated.
Theoretically scabies should be cured in a very short
time, but practically and really this is frequently not
the case; the reason is simply because the application
has not reached and destroyed the life of all the bur-
rowing insects.
Often in the treatment of scabies an artificial derma-
titis will be excited by the measures used, which masks
the real disease ; and sometimes one has to wait, using
appropriate soothing and cooling remedies, and then
return to the scabies treatment, if needed.
Do not forget that these diseases may be re-acquired
from parasites lurking in the clothing, so that the under-
clothes and bed linen used should be specially boiled
and ironed; in the hospital we have them treated
by dry heat, in a special oven. I have known a reinfec-
tion from gloves which have been heretofore worn, and
once, I believe, from a muff. I have the gloves which
have been previously worn used in the treatment, the
hands being first thoroughly anointed with the appro-
priate salve and the gloves kept on much of the time.
Pediculosis. While much more common among the
poorer classes, one constantly sees both head and body
lice among the better-to-do classes, and I have even met
them high up in the social scale. Poor kerosene oil, or,
better yet, crude petroleum, is the best application for
lice in the scalp, as it certainly kills the insects and also
destroys the life of the nits, which may hatch out later.
One thorough soaking of the head, for twenty-four hours,
with frequent re-application of the oil, is quite sufR-
110 PEIXCIPLES AND APPLICATION OF LOCAL
cient ; after this a good shampoo, and some bland oint-
ment to any sore places, will generally suffice to elimi-
nate the trouble; the nits are found loosened and
may be worked off the hair. White precipitate oint-
ment is efficient in killing the living insects, but it does
not reach the nits ; the same ^ay be said of stavesacre,
in lotion or ointment.
For body lice thorough bathing and white precipitate
ointment, wdth a trifle of carbolic acid, is still the best
mode of treatment; with, of course, special attention
to the underclothing, to kill any adhering nits.
The vegetable parasitic diseases, ringworm, favus,
and tinea versicolor, require quite a different treat-
ment, namely, remedies which will penetrate the epi-
dermal layer of the skin, in which alone the micro-
organisms live.
Ringworm. On the parts of the body free from large
hairs ringworm is a comparatively easy disease to treat.
Often simply painting with tincture of iodine or the
use of some mild mercurial or iodide of sulphur oint-
ment will soon destroy the parasite, tricophyton, and
effect a cure.
But on hairy parts, the scalp and bearded face, when
the disease has gained any foothold, the treatment is
quite a different affair. Remember what was said in
the first lecture in regard to the anatomy of the hair
follicle and you will better understand why these cases
are often so rebellious, and you will better plan your
remedies so as to reach deep down among the epithelial
elements which form the root sheaths of the hairs.
The X-rays are reported on enthusiastically by some
TEEATMENT IX DISEASES OF THE SKIN 111
for the cure of ringworm of the scalp, and I have shown
you some cases where this had been very effective. But
be careful not to produce too great alopecia, which may
be permanent, as has been done occasionally, nor to
burn the surface, as has sometimes happened.
For early cases of ringworm of the scalp, when first
discovered, the tincture of iodine, with half a drachm
of glycerine to the ounce, painted well, morning and
night, on the spots, and for some distance around, will
sometimes quite suffice to arrest the trouble. But the
disease is so insidious that you must not be deceived,
or judge too soon that the patient is cured; multitudes
of cases are allowed, by imperfect treatment or by total
neglect, to run on until the fungus has penetrated the
follicles deeply over large or many areas, and in such
cases it will require your very best efforts to reach and
eradicate it.
Epilation has been spoken of as necessary in ring-
worm, but unfortunately, if the disease is at all ad-
vanced, the hairs are so thoroughly affected that they
break off at the level of the skin and leave the follicle
still filled with the diseased stump, into which few rem-
edies will penetrate; but it should be practiced to the
fullest extent possible, and more or less continuously,
even to a slight distance around the area which is evi-
dently affected.
To show the difficulty of securing the penetration
of remedies, I may tell you that I have extracted hairs
from a region where the tincture of iodine had been
freely painted, and the hairs were found stained with
it only a little over half way down the root, whereas the
112 PEIXCIPLES AND APPLICATION OF LOCAL
fungus penetrated far below that point. Sometimes in
old cases it seems almost hopeless to attempt to effect a
cure, but, on the other hand, if left to itself the disease
flourishes and is a constant source of infection of others,
and patient, intelligent treatment should be insisted
on, even over a greatly prolonged period. You all
know, however, that with the occurrence of puberty
the disease yields more easily, and sometimes disappears
spontaneously.
For many years, both at Randall's Island, where I
had fully three hundred cases under treatment at once,
and in this hospital, where, with the Country Branch,
we once had over fifty cases on hand, almost every con-
ceivable method has been tried, under my direction, and
I confess that to-day I hardly know what to advise you
as the best, in really stubborn cases. I have great hopes,
however, that we may learn to use the X-ray in such a
manner as to effect a relatively speedy cure in a larger
proportion of cases, and that is the method of treatment
which we are now pursuing mainly in this hospital, both
with ward patients and in the out-patient department.
Most of the ointments containing mercury, iodine,
sulphur, and also chrysarobin, or chrysophanic acid, are
destructive to the parasite, and may be used with
advantage; only care must be taken not to make the
applications too strong. Beta-naphthol is also an effi-
cient parasiticide.

TKEATMEXT IN DISEASES OF THE SKIN 113
When the disease has reached deep down into the
follicle, from what I told you of the constriction about
a third of the way down, it is readily understood that
the aolid particles contained in most ointments cannot
penetrate while the broken-off hair is in the follicle.
We must then use those remedies which hold the para-
siticide in solution, and lotions of bi-chloride of mer-
cury, even two to ten grains to the ounce, repeatedly wet
on the parts, will penetrate somewhat: of course great
care must be taken in their employment. It has been
asserted that these can be made to penetrate the skin
by electrolytic action, but after trying this some time I
could never satisfy myself of its efficacy.
The oleate of mercury, about ten per cent., is a very
good remedy, as also citrine ointment, diluted with
vaseline two to four times, both very well worked into
the affected area. Also iodine ointment or a compound
of equal parts of iodine and mercurial (blue) oint-
ment (Formula 19, p. 42), thoroughly rubbed together;
this must be diluted two to four times with vaseline for
most skins. Oleate of copper has been highly extolled,
but I could never get any great success w'ith it.
One word in regard to making these applications.
For many years I have used a stiff stencil brush (and
it is necessary to cut off the bristles in order to secure
proper stiffness), and at Randall's Island, especially,
my directions were to rub the scalp with the appropriate
ointment just as long and hard as the child could possi-
bly bear it. In all this treatment, whatever application
is used should be kept on the affected areas all the time,
and reapplied with friction several times a day: the
114 PRINCIPLES AND APPLICATION OF LOCAL
child should wear a specially-made muslin cap all the
time, which is to be frequently washed.
Favus. Although this is also a rebellious affection,
it need not be nearly so refractious to treatment, as
ringworm, trichophytina tonsurans. In this disease the
hairs are not so disintegrated by the fungus, achorion
Schoenleinii, but can be quite easily extracted, and so
the remedies can be made to penetrate the diseased folli-
cles. But practically the disease is most stubborn, partly
because few recognize its true character, and often will
not secure or submit to sufficiently long and serious
treatment to secure a complete cure. It is easy to take
off all the crusts, and to keep the surface apparently free
from disease, and only reddened; but as long as this
redness remains the micro-organisms are deep in the
skin, and will surely reach the surface and luxuriate
again, if all restraining influences are removed.
The X-ray is also valuable in fa\"iis, and you have
watched at the hospital, cases in which its wonderful
effect was apparent ; the scalp was denuded of hair by
its action, but was finally covered with a luxuriant
growth of fine curly hair, apparently free from all
disease, even weeks or months after treatment. I may
say that in the hospital we are really relying on the
X-ray very largely, both in ring^vorm and favus, and
while it is rather too soon to speak positively, I believe
that it will prove to be a great aid in the future in man-
aging these heretofore very rebellious diseases.
For many years I have used with good results the
compound mercury and iodine ointment already men-
tioned (Formula 19, p. 42), in conjunction with com-
TREATMENT IN DISEASES OF TUE SKIN 115
plete and persistent epilation. This is generally too
strong as it is, and should be diluted with equal parts
of vaseline at first, increasing the strength as needed.
It should be well rubbed in with a stencil brush, at least
twice daily. The following ointment, well rubbed in,
may also be used with advantage :
49. ^ Olei cadini 3i

n\ ft. Unguent.
Tinea Versicolor. This third chief vegetable par-
asitic disease of the skin is a very different affair, and
its treatment is relatively simple ; for the fungus, micro-
sporon furfur, has relatively little vitality, and effects
principally the external layers of the epidermis.
But let me caution you against believing that all
cases are entirely cured when there seems to be no longer
any of the brownish patches on the surface. For the
fungus does penetrate the hair follicles somewhat, and
when treatment is of too short duration the eruption will
crop out again. Also there may be re-infection from
spores which have been retained in the underclothing ; so
that in reality many patients will often have the erup-
tion over a period of many years, in spite of more or less
energetic treatment at times.
The treatment is exceedingly simple, and there is
really but one remedy that is often used for it, and
that is hyposulphite of soda in watery solution, one
to two drachms to the ounce. The surface should be
116 PEIXCIPLES AND APPLICATION OF LOCAi
frequently washed, pretty severely, with soap, and the
lotion freely applied night and morning. In rebellious
cases sulphur vapor baths may be taken, and sulphur
soap, or one with naphthol may be used. Also any of
the mild mercurial, sulphur, or iodine ointments will
remove the eruption, but some treatment should be con-
tinued for a long time after the skin seems perfectly
normal.
We come, finally, to still quite a different class of
cutaneous affections, where the treatment has yet an-
other aim or object from any that has preceded: I
refer to what are called dermatologically neoplasms, or
new growths in the skin, and for them we require
destructive agents and methods. The principal diseases
referred to are lupus and epithelioma.
Lupus. In the last lecture (p. 59), I alluded to the
semi-surgical treatment of this disease, by the curette,
dental burr, and the nitrate of silver stick, which latter
I demonstrated on a patient at a recent clinical lecture.
I also mentioned the use of the X-ray and radium, which
are often most valuable, especially the former. I like-
wise touched upon the Finsen light, as used in Copen-
hagen (pp. 67, 68).
In former times ointments of various kinds were used,
but be assured that no mild ointment will ever cure the
disease. A strong iodide or mercury ointment will
sometimes reach down into the crypts formed in the
skin and destroy the disease, but this is a very painful
and tedious process, and I think that few who know
much of dermatology ever attempt now to cure the dis-
ease with ointments.
TEEATMENT IN DISEASES OF THE SKIN 117
Epithelioma. Most of you have seen, in the clinic,
some of the really brilliant results which we have had
with the X-ray in epithelioma ; in suitable cases, where
it acts efficiently, and is rightly employed, it leaves really
nothing to be desired in the way of treatment, especially
in epithelioma about the face.
But now and again the disease seems rebellious to this
agent, and in certain classes of cases experience has
shown that it is not best to employ it. Thus, epithe-
lioma of the lip is not, as a rule, reached by it, if it be
at all far advanced, and most observers agree that sur-
gery offers the best prospect. Time forbids telling you
much that I would like to, and I must refer you to
literature.
I have already mentioned curetting in epithelioma,
which, in certain cases, if thoroughly done, is certainly
very satisfactory. I will only mention that, after soak-
ing the scraped surface with peroxide of hydrogen foi
a minute or two, or touching it with pure carbolic acid,
I fill the cavity with powdered pyrogallic acid, and,
with a trifle of cotton over it, I leave it untouched for a
week or more; when the crust falls I have frequently
found the surface perfectly healed, and the disease erad-
icated, if the curetting has been thorough enough.
Marsden's paste, made of equal parts of powdered
arsenious acid and gum arable, wet with water, is an
efficient remedy to destroy epithelioma; a single thor-
ough application, left on long enough, is often quite
sufficient to eradicate a small lesion. The constant poul-
ticing every two hours or so, until it heals, is rather a
troublesome process, but, I believe^ is the surest way
118 PKIXCIPLES AND APPLICATION OF LOCAL
to secure a perfect result, with practically no tendency
to recurrence.
Before closing, I would like to say a word in regard
to the local treatment of syphilitic lesions.
Syphilis. For the primary sore I believe the black
wash to be still the best remedy, kept on all the time,
on absorbent cotton. When there is much discharge it
may be dusted first with calomel ; I believe that no one
advocates now touching such sores with nitrate of silver.
Black wash is also best for mucous patches about the
anus and genitals.
Mucous patches in the mouth yield very well to a
watery solution of bi-chloride of mercury, one to three
grains to the ounce ; this should be applied with a bit of
absorbent cotton, on a toothpick, several times daily.
Chromic acid, ten grains to the ounce of water, is excel-
lent for more chronic lesions in the mouth.
One can often modify very greatly the early, acute
eruptions of syphilis, especially on the face, neck and
hands, by the free use of applications which are of serv-
ice in congestive, non-specific eruptions, namely, such
as the calamine and zinc lotion (Formula 3, p. 30),
freely and repeatedly applied. Indeed, many of the
cutaneous lesions of syphilis are best treated by remedies
which are of value in similar ordinary skin affections,
and do not, as a rule, require mercurial treatment.
In ulcerating syphilitic lesions, when the patient is
under full and sufficient anti-syphilitic treatment, very
little local treatment is needed, and that often of a very
simple kind ; I want to remind you of the remarkable
resiilts which we saw in one of the clinical lectures this
TEEATMENT IN DISEASES OF THE SKIN 119
winter, simply from the application of absorbent cotton
on the gummy ulcerations about the knee and leg. This
plan of treatment I have employed for many years, and
time and again I have seen surfaces which had pre-
viously failed to heal under various ointments, which
were judged appropriate, cicatrize kindly and rapidly
when only cotton was used. This should not be changed
too often, nor torn off from raw surfaces ; if it adheres,
the dressing is to be soaked with water, and when it
comes off an application of peroxide of hydrogen is
made, and the absorbent cotton, in thin layers, replaced.
In deeper lesions, gummata which have not broken
externally, and in periosteal nodes, very excellent results
may be obtained from the rubbing in of a mixture
made of equal parts of blue ointment and iodine oint-
ment, well rubbed together (Formula 19, p. 42) ; this
is a little strong for some skins, and may be required to
be diluted, to avoid irritating the surface.
In this necessarily hurried glance over the subject of
the local treatment of diseases of the skin, in these lec-
tures, there are very many matters which could not be
touched on, and many others which were only men-
tioned, which could well be elaborated greatly. But,
gentlemen, my aim was not so much to attempt to give
you a perfect knowledge of the local treatment of all
cutaneous diseases, but rather to afford material for
thought, and principles of treatment which you can
apply in many directions. You realize, perhaps, a little
more clearly than before that the proper local treatment
of diseases of the skin covers a pretty large field, and
120 PEINCIPLES AND APPLICATION OF LOCAL
calls for thought and judgment, as well as knowledge of
the action of remedies. And you see, perhaps, somewhat
more clearly, how impossible it is for the various quack
and semi-quack preparations, which are advertised, to
be of any real value in skin diseases in general. Un-
doubtedly they each may be of service in special cases,
as they probably all have originated in various prescrip-
tions of physicians, which have seemed peculiarly valu-
able to some case or cases. You also see that oxide of
zinc ointment, while excellent for certain purposes, has
its limitations.
Finally, in closing, I must repeat what I said at the
beginning, that local treatment, in the large majority of
cases of cutaneous affections, is only a part of proper
dermatological therapeutics, and to be really successful
one must study the patient in all directions, as indicated
in my lectures of last year, and apply all the medical
acumen possible, in order to reach and rectify the errors
of system or of some of its component organs, which are
at the bottom of most diseases of the skin. I would as
soon expect to succeed in plowing well with one handle
to my plow, or in driving safely w^ith one rein to my
horse, as I would to be really successful in treating dis-
eases of the skin by relying on local measures alone.
