tried to have connection with the bitch. During the day he made 
frequent attempts to copulate with her, but was each time re¬ 
pulsed. It was noticed at his last attempt that he suddenly fell, 
and lay cold and trembling. .Nothing was thought of this at the 
time, and he was put at once on a bed of straw and left for the 
night; the following morning he was found dead. Autopsy re¬ 
vealed the peritoneal cavity filled with fluid, which was found to 
consist principally of urine; the bladder was relaxed and intense¬ 
ly congested, and showed a rent on its interior surface, near the 
fundus, an inch and a quarter long; the lower portion of the 
small colon and the rectum were impacted witli hardened foecal 
matter, and there was also well marked symptoms of peritonitis. 
Is not the probable explanation of this lesion the fact, that at 
the time of copulation, having a full bladder and impacted rec¬ 
tum, the violent exertion and venereal excitement were sufficient 
to cause the rupture of the walls of the viscus ? 
VESICAL AND URINARY CALCULI IN AN OLD DOG. 
On the afternoon of the 14th of December, an old dog, blind, 
and weighing about forty pounds, was brought to the clinic, with 
the following history; For the past few days he had constantly 
been trying to pass his urine, straining violently at each attempt, 
but failed in micturating or passing any faeces; his belly had be¬ 
gun to swell and gradually grown larger. About a year ago it was 
reported he had a similar attack, and was said to be promptly re¬ 
lieved by the use of sweet spirits of nitre. The animal lay pros¬ 
trate on the floor in a comatose condition. The abdomen was dis¬ 
tended and presented a large tumor, smooth, placed more 
towards the right side of the abdomen when the animal was made 
to stand up, movable from side to side; this enlargement was 
hard and tense, resembling in general appearance and feeling a 
large fibrous growth. Taking into consideration the condition of 
the patient, his age, his infirmities, the owner was advised to have 
him destroyed, which was complied with—cliloroformization.
