[By M. J. Biol.']. —This unusual case occurred twenty-five years 
ago, says the author. The cow had calved and had eversion of 
the uterus. She was tympanitic-, lying in the costal position 
threatened with asphyxia, when Mr. B. was called to see her. 
Her condition was as follows i u Costal decubitus 5 rumen enor¬ 
mously distended 5 extremities extended and now and then 
struggling, eyes staling and protruding* mouth widely open 5 
breathing short, rapid, dyspnceic ; almost pulseless ; rectum 
prolapsed and cyanosed. Toward uterus, the uterine cornu 
anteriorly gravid and completely eversed, free from placenta, 
appears as a large membranous sac, very thin, purplish, flabby’ 
soiled with blood and manure, and measuring, including the 
vagina (also prolapsed), about 30 centimeters in length. In¬ 
creasing the severity of the situation, there was a big ball of rye 
straw, the size of the arm of a man, perforated through and 
through the uterus, some fifteen centimeters from the prolapsed 
vagina. This was the result of the manipulation used to pull 
the animal out of the barn.” Perhaps it would be better to let 
the butcher finish her? However, trocar was thrust into the 
rumen and tympanitis subsided. At the same time, as it went 
on, the contractions of the uterus began to return, from the ex¬ 
tremity of the horn toward its base, in its width as well as in its 
length. The tear seemed to-reduce-also—and after a short time, 
reduction was completed after thorough cleansing of the parts. 
The cow made a complete recovery.— (Rec. de Med. Vet.) 
New Means to Diagnose Tuberculosis.— Dr. Riort has 
used in human patients the following mixture in the diagnosis 
of tuberculosis : Chloride of sodium, 5 parts ; sulphate of sodium, 
10 parts , distilled water, 1000. Or, again : Chloride of sodium, 
6 parts ; sulphate of sodium, 10; magnesia, 2; distilled water, 
1000. This serum is used like tuberculin. It gives fin tuber¬ 
culous patient a characteristic reaction nine hours after the in¬ 
jection. It is harmless in any case. These injections deserve a 
trial in veterinary practice, says the Sematne Veterinaire , but it 
does not give the dose to inject. 
Inguinal Fistula Due to Abscess of the Right Kid¬ 
ney \By MM. Butel and Bonrges.] —The horse was castrated 
in July. In November it had an abscess in the right groin and 
another the following February. When examined in the month 
of August of the same year it has a fistulous tract which al¬ 
lows the entrance of a probe up as far as the superior inguinal 
ring- There is ho champignon, the scrotum is clear, the ani¬ 
mal is not lame and his condition is good. Injections of cresyl
