THE MEDICINAL EFFECTS OF EMETIC TARTAR. 2 53 
pcared, may I be allowed to state the following particulars 
respecting it : — I believe tartarized antimony, either exhibited 
externally or internally, will affect the horse, the degree varying 
according; to circumstances. 
In the summer of 1833 I had an inveterate case of mange. 
The skin was corrugated and pustulous ; and no sooner was it ap- 
parently well, than it would break out again with increased vio- 
lence. I had been taught, and I believed at this time, that emetic 
tartar would under no circumstances affect the horse ; and as an 
experiment I thought I would try what would be the result of its 
application to this mangy mare. 
I prepared an ointment consisting of equal parts of tartarized 
antimony and lard. I had the mare brought out to the sun, 
and well dressed with the ointment all over the back and shoul- 
ders. In an hour or two I was called to see the patient. I found 
her in excessive pain, pawing and tearing up the litter, panting, 
trembling violently, &c., and the coat, where she had been dress- 
ed, staring, and so tender that she would not bear it to be touch- 
ed. Pustules arose all over the back and loins, and, after a few 
days, excessive sloughing commenced on the part to which the 
ointment had been applied. In the course of many months, and 
after an infinity of trouble, these sloughs did heal up, leaving 
places destitute of hair, with thick ridges and seams in the skin, 
as if the animal had been burned. I need not say that the 
mare was never troubled with mange again ; but certainly the 
remedy was worse than the disease. 
Shortly after this, I remember experimenting on a glandered 
horse, which I held over for the purpose. I shaved the hair off 
part of the hip, and applied the ointment, which was rubbed in 
twice. There was great irritation and swelling, and serous dis- 
charge, and a crust formed on the skin. 
From the few experiments I have made with tartarized anti- 
mony externally, I am of opinion that, if applied to the skin in a 
state of disease, such as mange, where there is any pustular erup- 
tion, abrasion of cuticle, 8cc. it will act as a caustic of a violent 
kind ; but if applied to the healthy skin, it may require a second 
or third rubbing before it will produce much effect, and with- 
out the rubbing is carried to an extreme length no sloughing 
will be produced. The same is the case with the skin of the 
human being, three and even four applications being sometimes 
necessary before vesication is accomplished. 
With respect to its use internally, I consider that, under cer- 
tain circumstances, it produces a very strange, lowering, and 
debilitating effect. In the month of June last, a troop horse 
was affected with some disease of the brain. When he was tied
