ROBERT W. ELLIS. 
of the New York University. I gave my consent, and requested 
that they notify members of the college faculty and such prac¬ 
titioners as they thought might like to be present. The time 
was set for 9 o’clock that night, and there were present Drs. 
Coates (chief surgeon of the College Hospital), Ryder, Bell, Rob¬ 
ertson, Dickson and myself, as well as the students of the college. 
The horse was very much emaciated since the last time 
that I had seen him, which was on the 5th, two days before his 
removal to the hospital. He was placed upon a table, and after 
being anaesthetized by Dr. Coates, Dr. Cronk made a trans¬ 
verse incision in the region of the left kidney, through which 
he passed his hand forward in the direction of the head, and 
came in contact with a large tumor; so large that he could not 
outline it entirely through the incision made, and invited in¬ 
spection and manipulation of it by those present before proceed¬ 
ing further. After this opportunity had been availed of by the 
practitioners and students, it was agreed by the practitioners 
that the tumor could not be removed with the hope of saving 
the horse, so far did it extend forward under the ribs, and his 
destruction, to be followed by a post-mortem, was decided upon. 
The horse was pithed, after which two or three ribs were re¬ 
moved, and a tumor weighing approximately forty-five to fifty 
pounds and measuring four and a half to five feet in circumfer¬ 
ence, involving and embracing the kidney, was revealed, which 
was soon removed, together with the kidney and the spleen. 
Dr. Cronk then split the kidney and found in its pelvis three 
calculi, one the size of a hen’s egg and two slightly smaller. 
While making this exploration of the pelvis of the kidney, the 
doctor’s scalpel passed accidentally through it, into the cavity 
of the tumor, and half a gallon of most foetid pus escaped (un¬ 
fortunately the doctor did not escape the pus). The cavity of 
the tumor was then washed out and the tumor, together with 
the kidney and spleen, were placed upon the roof of the college 
building for safe keeping and cold storage until morning, when 
I took the photograph which accompanies this report in the 
college pharmacy. The tumor was then sent, at Dr. Cronk’s
