CLINICAL CHRONICLES.

and the horse returned home. On the 6th of the same month, 
three days later, the animal manifested colicky symptoms. Dr. 
Kemp, who saw him, found him unable to pass his faeces, the rec¬ 
tum being filled with them, and the anus being somewhat swollen. 
A dose of physic was then given and nothing heard from him 
until the lltli, when he was sent to the hospital, to remain under 
treatment. On admission a number of fistulous openings are 
found round the anus, and under the sides of the tail. They 
allow the escape of a creamy looking pus, and communicate to¬ 
gether, the pus having burrowed its way under the caudal apon¬ 
eurosis. Upon pressure the pus escaped more or less tinged with 
blood. After pressing out the pus, the tail was washed out and 
dressed with carbolic solution and bandaged. 
November 14th, a catheter introduced into one of the openings 
on one side of the anus extends into the pelvis for a distance of 
about fourteen inches. The discharge is quite abundant. Same 
treatment. 
• November 15th, two little abscesses are found on the upper 
part of the tail. The suppuration seems to diminish from the 
other openings. 
November 18th.—Three other abscesses were found ready to 
be lanced, in the, inferior portion of the tail. All these are dressed 
with carbolic solution. They communicate together, the injection 
passing readily from one to the other. 
November 20th.—Another large collection on the upper part of 
the appendage. 
November 21st.—The collection at the root of the tail seems 
more swollen, and gathering. 
November 23d.—This has to be again freely opened by large 
incisions, running right across near the root. 
November 26th and 27th.—Seems to be at last doing well. 
Suppuration diminishes. No new abscesses forming. The hair 
has fallen off from about two inches from the root of the organ, 
at places where the abscesses had formed. 
November 29th.—The anus is more swollen again. 
November 30th.—Rectal examination reveals a large swelling 
inside, on the left side of the pelvic cavity.
