REPORTS OF CASES. 
The horse presented a very unthrifty appearance—shaggy 
coat of hair, impaired appetite, feeble circulation, and he was 
very dull and emaciated. I made a rectal examination and 
found a large calculi in the bladder. The case was explained 
to the owner, who consented to the operation, lithotomy. 
The horse was prepared by feeding a laxative diet forty 
eight hours, then his feed was omitted ten or twelve hours, 
and then an ounce ball of chloral-hydrate was given and 
the horse secured in the stocks for the operation. The peri¬ 
neum was then thoroughly washed, first with soap and water, 
then with a solution of bichloride of mercury i-iooo. 
The catheter was passed into the bladder, and an incision 
made upon it at the perineum so as to freely expose the interior 
of the urethra ; the catheter was then removed and the lithot¬ 
omy forceps introduced through the wound into the bladder, 
and with the left hand in the rectum the stone was guided 
into the forceps and gently removed. It was large as a hen’s 
egg and weighed three ounces. 
The bladder was washed out with tepid water, and the 
lips of the wound kept together by sutures, and the parts 
dressed antiseptically with solution of bichloride of mercury 
i-iooo. 
A large soft sponge was tied on the wound and kept sat¬ 
urated with the solution for six or eight days. 
The parts healed rapidly, and very little urine escaped 
through the wound. On the second day his temperature rose 
to 102°, but was normal by the fifth day. 
There was but little swelling. The horse did not miss a 
feed after the operation, and was ready for his work in three 
weeks. 
I saw him about three months after and he was in fine con¬ 
dition, fat and sleek.
