certain. Not only do we find his remains, together with those 
animals that have been extinct, but also rude drawings of him 
on tusks of ivory and bone have been found in the caves occu¬ 
pied by pre-historic man as an abiding place. The first au¬ 
thentic account of the domestication of the horse is found in the 
tombs and on the monuments of the nineteenth dynasty of 
Egypt, 1900 years before our era, and then in those tombs we 
see paintings, representing men in the act of administering 
medicine to sick animals. Showing that at that remote period 
the veterinary art was known and practiced.

AN INTERESTING POST-MORTEM. 
By L, H. Hempelmann, D.V.S., House Surgeon to the American Veterinary 
College—Hospital Department. 
On December nth, 1893, a bay gelding was presented to 
the college by Dr. J. S. Lamkin of Yonkers, N. Y., who gave us 
the following history: 
The horse had been troubled with incontinence of urine for 
about two months which had been treated, but without success. 
The urine was always mixed with mucous and at times con¬ 
tained some blood. 
The patient was placed under observation ; every day his 
bladder was emptied by a catheter and the urine—about two 
ounces usually—collected. On rectal examination the fundus 
of the bladder seemed to be somewhat thickened, but no calcu¬ 
lus could be felt. 
A week after the patient came under our observation, it was 
decided to explore the bladder. The urethra was accordingly 
opened and a sound introduced into the bladder, but nothing 
definite could be discovered. 
The animal was then destroyed for a post mortem examin¬ 
ation, which in many respects proved to be highly interesting.
