given. This occurred several years before that valuable opinion 
to which Mr. Swinfen alludes was given by Dr. Parkinson. 
The disciples of White continue its use, and so, I believe, 
do some respectable practitioners ; but, generally speaking, it 
has given way to emetic tartar, which has its full diaphoretic, 
without its emetic effect on the stomach of the horse. 
He would be a bad practitioner who gave either the one or 
the other to cattle. 
There is, however, another patient — one which the veteri- 
nary surgeon is beginning to consider a little worthy of his 
care — the dog. Nature has formed him with a most irritable 
stomach — even the grass which he plucks will cause him to 
vomit. In him the use of emetic tartar is altogether precluded, 
except as an emetic : but we want, as in distemper, and in 
many febrile or chronic diseases, a determination to the skin, 
which the antimonial powder readily produces. Hence, and 
in cases like these alone, are we permitted the use of this drug. 
Many a case of fever and distemper is saved by it. It is, in 
a manner, our sheet-anchor in distemper. 
We feel grateful to Mr. Swinfen for addressing us on such a

ON DEEP FIRING. 
By Mr. John Scott, P.N., Kildare , Ireland. 
Being determined to test the truth of the assertion, that deep 
firing would produce destructive sloughing, and even death, and 
relying on the faithfulness of Mr. Turner’s report of the opera- 
tion, I fired a three-years old black colt for a large splent, situ- 
ated close to the knee, on the inside, and causing great lameness. 
I made three longitudinal incisions with tiie iron, at as near to a 
white heat as I could obtain it, quite through the skin, and ex- 
tending the whole length of the tumour — the middle or central in- 
cision being the deepest, and penetrating to the periosteum, which 
I divided from end to end over the enlargement. 
The operation was performed on the 18th of Oct. 1838, the 
horse having been previously prepared by reducing his system 
to comparative weakness — his keep for four or five days con- 
sisting of bran mashes and water supplied sparingly. I applied 
cold water to the wounds for twenty-four hours without ceasing ; 
and occasionally, until the fourth day, when its use was discon-
