TYMPANY OF THE STOMACH AND INTESTINES. 
By the Same. 
A white mare, regimental No. 2004, of the 1st troop, was 
admitted into hospital on the morning of the 23d of June last, 
with symptoms of abdominal pain. I was made acquainted 
with the circumstance about half-past ten a.m. ; and, although, 
I attended immediately, so sudden and sharp was the attack, 
that I had only arrived a very few minutes before she died. 
I was informed that the mare was unable to stand, after 
her admission, and that she had been sitting upon her 
haunches. She was now lying stretched out on her side, 
bathed in a most profuse, but cold, perspiration, foaming 
at the mouth, and making constant, but ineffectual, efforts 
to eructate. Her eyes were fixed, and nearly closed; she 
had no pulse, her abdomen was remarkably tympanitic, and 
she was straining violently. A little blood was issuing from 
the rectum, and the gut was slightly protruding and much 
congested. She struggled a few times, groaned, and then 
expired. 
Autopsy. — Immediately the abdominal cavity was laid open 
the intestines burst forth with irresistible violence ; both the 
stomach and intestines throughout being enormously dis- 
tended with flatus. 
There was but little ingesta in the viscera, and this was 
frothy from the admixture of gas. The contents of the 
stomach were very sour, and there were a number of very 
minute thread-like worms in its interior. An inflammatory 
blush also pervaded its villous coat. About a pint of fluid 
was discovered in the pleural sacs, and both the lungs and 
the pleura pulmonalis, showed the existence of acute in- 
flammatory action. 
VALVULAR DISEASE OF THE HEART 
ASSOCIATED WITH GASTRITIS. 
By C. T. Shorten, M.R.C.V.S., Ipswich. 
[ readily embrace an opportunity just afforded me of 
sending you a portion of the heart of a mare in which the 
tricuspid valve is in a state of disease, and which I am inclined 
to think is somewhat unusual ; at least I have only met
