REPORT OF CASES.

fracture on the femur is fiat, smooth here and there, granulating in some 
places. Where is the other piece of the bone ? All that can be found is 
a small bony piece, imbedded with the thickened tissue surrounding the 
joints. The cavity of the acetabulum is almost destroyed; instead of it, 
its surface is smooth, corresponding in shape to that of the femur, at the 
upper part of which is the attachment of the capsular ligament already 
referred to. The inter articular ligaments could not be dissected. 
In other words, there was a fracture of the head of the femur with 
dislocation at the hip joint, and commencement of ankylosis through 
the bony organization round the joints, which would have been complete 
had the animal lived longer. 
D. Comminuted Fracture of Pelvis—Internal Hemorrhage—Death. 
This was a bay horse, about sixteen years old ; he was driven about 
two miles after leaving his stable, and stopped in the middle of the 
street. While standing his mate slipped and fell, but in so doing threw 
him down ; being unable to get up he was brought to the Veterinary 
College in an ambulance some four hours after. 
Condition on admission. Pulse weak, 48; respiration labored, num¬ 
bering 22; while down he groans and strains to rise; left eye (upper 
one) dilated; cheeks flabby during respiration. The animal attempting 
to raise himself a sling was passed under him, and he was assisted to 
his feet. It was found then that the left hind leg was powerless; the an¬ 
terior external angle of the ilium was much lower and farther from the 
median line than its fellow. Upon rectal examination the sacro-iliac ar¬ 
ticulation was found to be ruptured, a fracture extending the entire 
length of the pubic symphysis with a part running from the acetabulum 
to the obturator foramen. 
While standing for examination the animal trembled violently, the 
pulse became more rapid and weak, the pupils more dilated, and being 
lowered down he died within ten minutes afterwards. 
Post-Morie?n .—The tissues in the internal femoral region were filled 
with blood; the pelvic cavity and its contents were surrounded with clots 
also; the floor of the pelvis being broken in about twenty pieces, with 
the main points already given above.
