A NEW KSCHAROTIC APPLICATION. 
Canker in the foot of the horse. — If the frog is bruised or 
wounded, the detached and loose portions should be cut away ; 
the exposed sore part washed with vinegar, and then this caustic 
lightly applied once or twice ; but if there is much ulceration, the 
foot should be well pared out, every separated or loose portion of 
the horn removed, or any ulcerated or cancerous part of the sensi- 
ble frog itself; and then, after the exposed surface has been washed 
with vinegar, a feather slightly wetted with the escharotic fluid 
should be drawn over it, and moderate pressure applied to the 
sore. The dressing should be repeated every third or fourth day, 
taking care that every part of the surface that has not a healthy 
appearance is touched with the fluid. During the whole of the 
treatment, if the horse is not very lame, and the weather is dry, 
he may be gently worked. In the course of a month a complete 
cure will usually be effected. 
Cracks in the heels. — After having well washed the sores with 
soap and water, and removed every portion of hardened matter that 
may surround them, they should be lightly touched with this mix- 
ture. Tw r o or three days afterwards, this may be repeated, if the 
first application has not fully effected the purpose. The escha- 
rotic, however, must not be applied too frequently or too freely, 
lest the sores should be enlarged or deepened. 
Grease — Dartres humides. — The horse, in marshy countries, or 
in an ill-managed stable, in which the dung and urine are suffered 
to accumulate, is subject to a scurfy eruption on the legs and feet. 
As soon as it appears, the hair stands on end, the skin thickens, 
and a fetid secretion of limpid fluid, which soon becomes concrete, 
takes place. If care is not taken, this extends over the fetlock, 
and particularly the heels, and, perhaps, causes thrush and swelled 
legs. This eruption is easily removed, although in a very ad- 
vanced stage, by cleaning the part first with soap and water, and 
then applying a little of this mixture once in three or four days. 
Two or three applications will almost always suffice. 
Swelled legs. — I have never used the escharotic in this com- 
plaint, except in a very early stage of it, and before it had attacked 
the pasterns. The same precautions are necessary as in dartres. 
I have no doubt that this fluid would be exceedingly useful in 
farcy ulcers, and in all wounds of bad character, particularly in 
the ulcers of cows attacked with aphthae. 
This escharotic has a peculiar action on the morbid secretions of 
the skin and the mucous membranes; and it is to this property, 
w r hich it possesses in a high degree, that we must attribute its 
usefulness in a crowd of analagous cases, and which, at first sight, 
appear so different from each other.
