The opening of the abdomen was carried on with much care, 
to collect as nearly as possible the fluid exisiting there. This was 
successfully done, and nearly thirty-two gallons of liquid were 
collected. This was at tirst of a yellowish color, clear, but be¬ 
came muddy and reddish towards the end ; it was more or less 
mixed with granular deposits of fibrinous structure. The cavity 
being laid entirely in view by the cutting of the abdominal walls, 
the most magnificent lesions were exposed. 
Every part of both the parietal and visceral layers of the 
peritoneum was increased in thickness varying from three or four 
lines to half an inch. Fibrous deposits were found all over 
the intestinal canal, over all the abdominal organs, and the poste¬ 
rior face of the diaphragm was considerably thickened by their 
presence. 
The intestines were considerably reduced in size, empty and 
covered with the produces of that extensive peritonitis. Their 
interior was empty, and the mucous membrane was pale and pre¬ 
sented the folds of its surface as if the animal had died from 
starvation. Peyer’s patches were healthy. 
The spleen was quite healthy in structure, except towards its 
free extremity and over its external surface. The structure of 
the apex was somewhat softer than the other parts and easily 
torn. The peritoneal coat was considerably increased also in that 
part of the organ as much as half an inch. 
The kidneys were, in all appearances, healthy, though some¬ 
what pale in color. 
On examination, the liver was of a natural color, of natural 
hardness; its capsule was easily torn and separated from the 
tissue underneath. 
In trying to remove the small colon, in the right hypochondriac 
region was found floating in the abdomen, amongst the folds of 
the intestines, a large tumor, hanging to the small mesentery as 
an apple to its stem, and weighing eighteen and a half pounds, 
and measuring about thirty inches in circumference. This must 
have given rise to the suspicion of enlarged liver, as it was felt 
during life in the right hypochondriac region. Its shape, some¬ 
what ovoid, was, however, irregular, its external surface bosselated
