gan to wean her colt, five days after which she had an attack 
of colic while driving upon the road at night. The following 
morning at 8 o’clock she appeared to be all right. At 9 o’clock 
of the same day she had another attack, which lasted about 
four hours; she was then put upon her former light diet 
until her death. The result of the post mortem, made one 
hour after death, was as follows : abdomen enormously distend¬ 
ed with gas, upon opening which a large quantity of fluid 
and feed escaped; peritoneum and intestines highly in¬ 
flamed ; great curvature of stomach ruptured to the extent of 
seven inches, stomach contained a large amount of food and 
six small worms; about five inches from the oesophagus upon 
the anterior face of the fundus of the stomach, was a round 
hole, the size of a silver dollar; the edges of this hole were 
entirely healed, showing that it had existed there some time, 
and beyond doubt was the cause of her repeated attacks of 
colic. Having never seen a case of the kind before, 1 thought 
it might be of interest, and so submit it.

PECULIAR MICROBIC TUBERCULOSIS OF CATTLE. 
BY ME. OOUEMONT. 
The author has found in the pleuritic tubercles of a cow, 
which seemed to be affected with ordinary tuberculosis, a 
micro-organism which is not the bacillus of Koch and which 
does not resemble any of the various microbes described 
among the various forms of tuberculosis. Pure cultures of 
this micro-organisms produce, in the guinea pig, tubercles 
like those of tuberculosis proper, and grows with great rapid¬ 
ity. The micro-organism is abundant in the blood, and pre¬ 
sents someanalogy with the microbe described in 1881 by 
Toussaint in the blood of tuberculous cattle .—Society of Biology.
