a solution of the problem. Patches of coagulated necrosis were 
commonly seen in the liver, more frequently in this than any 
other disease. These might possibly be due to thrombosis. So 
far no bacteria have been found in them, and it is supposed that 
this condition may be produced by toxine. Hitherto all at¬ 
tempts at finding a specific microbe have failed. 
Mr. Groves then reported the following interesting case : 
The subject, a male dog, ten years old, of spaniel breed, 
brought to the college for treatment. History.—The dog being 
unable to walk in a straight line, and often falling down and 
lying down more than usual. This condition was noticed for 
about two weeks; the symptoms presented were a general de¬ 
bilitated condition, coat rough and dry, the tongue protruding 
from the left side of the mouth ; the neck was straight and 
sometimes inclined to the left ; the body resembled the seg¬ 
ment of a large circle, with its centre on the right side, lame¬ 
ness in the right foreleg and general paresis. Diagnosis.— 
Pressure on base of the brain, probably a tumor. Prognosis un¬ 
favorable. Treatment.—Useless, but the owner desired that we 
should do something, and he was given nux vomica, iodide of 
potash and gentian. Two months afterward the animal was 
brought back to be destroyed. The symptoms were much ag¬ 
gravated, the dog lying most of the time, but he could get up 
and when he tried to go fast fell down. When standing would 
brace himself against some object and when walking would 
walk almost sideways, always going to the right. His head was 
turned on its axis from the right to left, the right side being the 
highest. This was not continually the case, for he would at 
times hold his head straight. His vocal power was lost and he 
had difficulty in swallowing. Sight was not impaired. The 
dog was chloroformed and post-mortem held, which resulted as 
follows : The various organs of the body were found to be 
normal, but on the inferior part of the medulla there was found 
a tumor about the size of a marble. It was attached closely to 
the wall of the foramen magnum, so that it had to be separated 
with a knife. It was semi-circular in form, with a broad base. 
Dr. Gunn considered this an operable case and a surgeon 
would have been guided to the right lobe of the cerebellum as 
the seat of tumor. The diagnosis would have been wrong, but 
the surgeon’s incision would have been over the tumor, which 
could have been shelled out with a possible good result. The 
recognized symptoms of the disease of the cerebellum are al¬ 
most exactly those given by Mr. Groves, viz. : (A) Rotation of
