THORACIC AND ABDOMINAL DISEASE. 
and pale. The thorax contained a gallon of turbid serum in its 
right cavity, and a large portion of fibrin or plastic lymph inter- 
vened between the pleurae pulmonalis and costalis — firm adhesion 
in various parts. A portion of lung was likewise firmly adherent 
to the inferior part of the diaphragm — the left lobe of the lungs 
vascular, and the bronchi of both lobes filled with white froth. 
The pericardium contained about three pints of dark-coloured 
serum. 
Case II. — A year-old thoroughbred filly, of fine symmetry, 
the property of the same gentleman, was early in May last at- 
tacked with strangles in an irregular form, namely, in that of a 
catarrhal flux from the nose, which it was feared at the time 
would have caused suffocation ; but, by the usual treatment, she 
nearly recovered her strength and condition in three weeks. 
June the 8th . — A large abscess has formed on the side of the 
neck, just below the bifurcation of the jugular vein. A free in- 
cision was made at its most dependent part, and exit given to 
about two pints of pus. After a few days she, with several 
other colts, was sent to an off farm. 
I saw no more of her until June the 22d, when I was informed 
by her attendant that she would frequently eat her litter in pre- 
ference to good hay or corn ; that her coat stared and looked 
rusty ; her belly was getting larger, but no symptom of acute 
abdominal or other pain was observed. He saw her feeding with 
the other colts at twelve o’clock at noon, and at four o’clock in 
the afternoon she was found dead. 
Autopsy . — The abdomen, when opened, presented large masses 
of grumous pus lying loose upon the peritoneum, which was 
highly inflamed, and in the centre of the mesenteric glands were 
several immense abscesses, which, with their contents — principally 
pus and large clots of blood — filled a three-gallon pail. One of 
these abscesses had burst into the cavity of the abdomen, and 
produced acute peritonitis, which, no doubt, was the cause of the 
sudden death of the animal, as all the other viscera, &c. were 
healthy.
