and indurated swelling. This deviation permits the tracing of 
the clean tendon of the gastrocnemius down to its insertion. 
The perforatns alone is thickened. To the left of the tendinous 
cap, the os calcis is much enlarged, with the fibrous cord of the 
displaced perforatns on its external face. Immediately below 
the cap of the perforatns, the tendon is clean and of ordinary 
size ; but farther down, at the lower part of the hock, it is thick, 
tumefied, and globular. The deviations of the tendon exist as 
far as the lower third of the cannon and from the hock to that 
point the two tendons are traced side by side of each other. A 
little above the fetlock, the perforatns resumes its normal situa¬ 
tion. Besides these principal lesions, there were other second¬ 
ary ones : a large tendinous thoroughpin on each side of the 
cord of the hock and a synovial tumor, produced by the disten¬ 
sion of the inferior atl-de-sac of the tarsal tendinous synovial. 
There is no capped hock, but a little below the head of the os 
calcis, there is a fourth synovial dilatation.” Notwithstanding 
all these lesions and their serious nature, Quartier resumed his 
work after three months entirely free from lameness.

CANINE PATHOLOGY. 
Hernia in Dogs \By W. Paner^ M. R. C. V. N.]. —This 
interesting subject receives at the hands of the author three ad¬ 
ditional instances, which add much to the history of hernia. 
The first is that of a three months old pup, having a congenital 
umbilical hernia, which had become as large as a walnut. The 
treatment consisted in the application of a tampon of tow, held 
in position by strips of adhesive plaster. The little fellow was 
fed heavily; as he was a gluttonous eater, his abdomen was con¬ 
stantly more or less distended and by this the pressure of the 
tampon held the hernia in place. In six weeks the cure was 
radical. . . . The second is that of a bitch which had an 
ingtiiual hernia, so large that it trailed on the ground and 
interfered with the walking of the animal. The hernia was 
reduced, the skin carefully divided, and separated from the per¬ 
itoneum. The serous sac was ligated close to the inguinal ring 
and cut off. A large piece of skin was removed and the incis¬ 
ion closed tight by interrupted sutures. The recovery was com¬ 
plete in a month. . . . The third case was not so success¬ 
ful. A fox hound had been fighting and was badly bitten ; he 
had a bad abdominal hernia forming a tumor as big as the fist.
