serviceable in the stud again, although not entirely convalescent, 
as the lameness and enlargement were quite perceptible. 
Two years later he met with a mysterious accident that caused 
a rupture of the stomach, on which account I was called to make 
a post mortem examination, when I captured this specimen. 
INTESTINAL CALCULUS. 
By the Same. 
The intestinal calculus is one of a half peck that I removed 
from the pelvic curvature of the large colon, of a horse that suf¬

would put the foot to the ground upon the toe, about four inches 
in advance of the opposite foot. When urged to go rapidly, he 
would carry the limb in the air in a vertical manner. By the 
12th of October, an abscess had formed below the external angle

region of the joint. February 4th, 1878, I obtained the owner’s 
consent to destroy him. On my arrival I found him but little

very much atrophied. T destroyed him by injecting a strong so¬ 
lution of cyanide of potash into the jugular vein, which killed him
