has found as high as 22 per cent, of urea in the urine of azoturia. 
Post-mortem appearances .—Congestion of the meninges. The 
hlood often chocolate colored or somewhat tarry but not abnorm¬ 
ally fluid, asin the tarry hlood of anthrax, or deficient in red disks, 
as in leucocythemia. The color is probably due to the ad¬ 
mixture of the effete lymph. The liver is usually yellowish, en¬ 
larged, friable ; kidneys enlarged and congested, sometimes con¬ 
taining pus in their pelves, and the mucous membrane of the blad¬ 
der inflamed. The condition of the bladder is due to ammoniacal 
decomposition of the urine in a similar way to that found in old men 
with enlarged prostrate, the constant action and reaction of the 
mucous thrown out by the irritated viscus on the urine and the 
irritation of the urine assuring the secretion of the mucous. 
I call your attention to a sequel of azoturia, not mentioned, so 
far as I know, in English works. It is an almost complete atrophy 
of the crural triceps of the muscle of the fascia lata and in some 
cases of the glutei of one side. The first case I saw was in 
Philadelphia. I was called to “put in the stifle ” of a horse. I 
found the patella in its place, but imagined that I had a disloca¬ 
tion of the femoro-tibial articulation. I was satisfied that I could 
place mv hand on the tibial spine, and to show you that this great 
error of diagnosis was not due to my carelessness, two thoroughly 
qualified Philadelphia veterinarians agreed with me and also 
agreed t* at attempts at reduction would be futile, as, if by exten¬ 
sion and counter-extension on the limb while the horse was recum¬ 
bent the dislocation could be reduced, the condition would recur 
on rising. A big blister was placed on the affected side, and the 
horse was left to his fate. Imagine my surprise, when I saw the 
horse last summer as sound as a dollar, without a trace of the old 
trouble. 
Since then I have been consulted in several similar cases; 
have advised as treatment repeated blisters and the battery, with 
a long run at grass. This has been successful in each case, hut 
has required many months to bring about the result. The ap¬ 
pearance is peculiar. There is apparently a big hole in the affected 
flank and the femur is almost denuded of musculature anteriorly. 
Dr. Iluidekoper suggested to me that rupture of the psose was
