R. H. HARRISON. 
died during the day in convulsions, and was brought to the 
college for post mortem examination. 
Post mortem .—The lungs showed tubercles, especially marked 
on the right. The kidneys were studded over with small whitish 
nodules and streaks, which were surrounded by congested and 
hemorrhagic tissue. A section which was kindly examined under 
the microscope by Dr. Welch, pathologist to Bellevue Medical 
College, revealed that the nodules were composed essentially of a 
dense accumulation of lymphoid cells, which had led to destruc¬ 
tion of the uriniferous tubules; the infiltration of lymphoid 
cells extended from the nodules into the surrounding tissue 
between the tubes. In many places there was an infiltration 
with similar cells, where no abnormality could be detected. 
The nodules and streaks might have been considered as 
minute abscesses, and the disease process might be called one of 
acute interstitial or suppurative nephritis, for sometimes apparent 
tubercles present under the microscope the structure of minute 
abscesses, instead of the tubercles, but, finding true tubercles in 
the lungs, it would be preferable to consider it tuberculous rather 
than suppurative nephritis. 
The prostate gland was enlarged slightly. The bladder was 
distended with urine to its greatest capacity, and its mucous 
membrane was slightly congested. An attempt was made to 
find out the cause, by making a careful examination of the milk 
which they were in the habit of feeding the dog, but tuberculosis 
could not be traced, for the milk came from a distance in the 
country and was a mixture of the milk of several cows, and to go 
and examine the cows was impracticable. 
Epithelioma of the Tail and Anus. 
A large bloodhound, one of the largest of its kind, was sent 
to us from Staten Island; he was thought to be affected with 
hemorrhoids. 
When examined, a large tumor, the size of a large hen's egg, 
was found situated on the lateral surface of the tail, near its base. 
Its surface was excoriated and bleeding. It was well defined and 
bulging from the surface of the skin. Another was seated under
