REPORTS OF CASES. 
good; ate mess for supper, which consisted of boiled oats with 
little bran and six carrots; horse lay dowD and rested quiet six 
hours during night. 
January 9th. 
4 p.m. : Temperature, 104^°, F.; pulse, 90°; respirations, 40°. 
No appetite; anxious physiognomy; injected membranes; ears 
and limbs cold; I saw that there would be a fatal termination 
shortly. 
Morning, January 10th. 
No chance for recovery; had him destroyed immediately, and 
at necropsy found but very slight peritonitis, and renal fistula 
was pathological condition I had been dealing with ; there was 
nearly complete degeneration of the left kidney; there was the 
same kind of pus as in growth removed at operation ; the right 
kidney was greatly hypertrophied, weighing 2 lbs. and 13 oz. 
Now, the question arises : Was the tumor the result of the dis¬ 
eased kidney or vice-versa ; was renal fistula the result of suppura¬ 
tive nephritis ? It could have been the result of calculi, foreign 
body gunshot wound, or nephritis. There was no obstruction in the 
ureter. I have since learned that this horse never showed any but 
healthy-looking urine until time I mention after operation. Know¬ 
ing that there are but few cases of renal fistula recorded in human 
practice, and none in veterinary that I can discover, I sent you 
the kidneys, Mr. Editor, without making any examination to dis¬ 
cover calculi or foreign body, and regret very much that I did 
not preserve the tumor that I might have sent it also ; the tumor 
would certainly weigh one and a half pounds. Other interesting 
points in this case are that the horse should remain in such good 
condition, and that there should be such a variation in tempera¬ 
ture, pulse and respirations, in so short a time that there was no 
swelling, and but very slight soreness. The tumor misled me, 
from the fact of its being small on side next kidney— i.e., having 
a constricted portion on kidney side. I could have performed 
nephrotomy at same time with but little more trouble had I the 
slightest idea the kidney was diseased. I rather think it had 
undergone such a change that the renal artery would not have
