the horse came back lamer than ever ; the muscles of the crural 
and gluteal region partly atrophied, the synovial enlargement 
increased, and the leg always raised. 
The horse was cast down and a crucial incision made on the 
tumor. After having dissected the subcutaneous cellular tissue, 
and cut a portion off the tibial aponeurotis (aponearose jam 
Mere) and the membrane of the fascia lata, I passed, with the 
greatest difficulty, a strong thread through the tumor that would 
enable me to pull it in different suitable directions. The tumor 
was soon entwisted, and the horse was sent home, walking away 
about as well as before the operation, and the proprietor told to 
clean it once a day. 
On subsequent information I learned that the horse did not 
stand on the foot for over one week. But three months later I 
happened to see the patient again. He was laming a little—less 
when trotting than in walking, and when standing still he favored 
the operated leg, resting it on the toe. This lameness might be 
attributed, I think, to the loss of a portion of the membrane of 
the fascia lata and the tibial aponeurosis, as it did not seem to be 
the expression of any pain. 
The tumor was about inches long, inch wide, and about 
1 inch thick. It was hard to cut, grating under the knife 
(criant sons le tranchant chi bistouri), and consisted of cretaceous 
deposits, intermingled witli partially indurated cellular tissue, so 
as to give the whole mass a marbled color. These chalky depos¬ 
its were kept soft by the animal temperature and the circulating 
fluid; but one week after the operation the tumor had shrunk 
down to less than half its size, the chalky deposits being the 
only substance left. The mass was as hard as stone, and impossi¬ 
ble to attack with a knife. * 
POTT’S FRACTURE IN THE DOG. 
Presented to the N. Y. Pathological Society by A. Liautard, M.D., V.S. 
Gentlemen— The specimen I present for your examination 
this evening is one which I think can be considered as one of 
Pott’s fracture in the dog. 
The history of the case is as follows;
