REPORTS OF CASES. 
weeks, she got better, and was put to work, and on the following 
day she could hardly put her foot to the ground ; and when I was 
first called, she was suffering intense pain, and there was a ver} r 
foetid ichorous discharge issuing from the coronet at the heel and 
around the frog. 
I ordered the foot to be soaked well in warm water, and the 
next day I visited her for the purpose of removing the diseased 
horns. I first removed the sole and horny frog,, and then, by 
probing, I found it necessary to remove the wall, which I did by 
sawing through the horn just below the coronet, and tearing the 
wall off with a pair of pincers. The resulting haemorrhage was 
soon stopped with Mousell’s solution. After the removal of 
the horn I found the plantar cushion was gangrenous, so as 
to necessitate a removal of its surface. The keratogenous 
membrane, from the point of the plantar cushion extending 
over the anterior part of the plantar surface and the anterior 
border of the os pedis, was also gangrenous, so as to necessi¬ 
tate removal. The unhealthy tissue under the diseased mem¬ 
brane was cauterized with argenti nitras, and two exposed places 
qn the os pedis were scraped. During the operation the foot 
was well irrigated with a one-tenth per cent, solution of bichloride 
of mercury. After the operation the animal was placed in slings, 
and the foot was dressed daily with antiseptic cotton and a 3 per 
cent, solution of phenic acid. The gap in the keratogenous mem¬ 
brane closed very slowly, and just two months from the date of 
the operation it was entirely closed. In the meanwhile the wall 
grew very fast, so that now the lower border at the toe is within 
three-quarters of an inch of the sole, and the latter is thick 
enough, so that the injured foot bears its share of the animal’s 
weight. 
A LARGE VENTRAL HERNIA. 
Case No. 2.—A gray gelding, five years old, was let loose in 
a yard with some cows, and got hooked at a point below the right 
flank, about eight inches from the linea alba, and about five inches 
posterior to the border of the asternal ribs. 
The owner first discovered an abrasion of the skin and a soft 
tumor about the size of a hen’s egg. Some time after the injury
