ON THE RE-ABSORPTION OF PUS.

membranes. The pleurce. were as thitiy glistetiing, and transparent 
as in their natural state \ except that the sub-serous capillary 
system presented, here and there, faint arborescent injections. 
The surface of both lungs was thickly covered with ecchi/moses, 
at somewhat regular distances, and the largest of which did not 
exceed a lentil in size. Besides these ecchymoses there were 
numerous perforations, about the size of a pin’s head, forming a 
communication between the pulmonary tissue and the pleurae, 
and through which, probably, the pus that we found had made its 
way into the pleural cavity. 
The pulmonary substance had lost its sponginess—it would 
not float in water—it contained a great quantiti/ of infiltrated 
puSf mixed with serunij in its tissue, and which escaped on pres¬ 
sure being ihade. This pus resembled that which had been con¬ 
tained in the pleural cavities. Many small ecchymoses were 
remarked in the pulmonary tissue, 
Digestive organs. —The mucous membrane of the pharynx 
was strongly injected, and a great quantity of pus was found in 
it of the same smell, and having the same character, as that in 
the abscess beneath the jaw. A little pus was also found mingled 
with the mucus of the stomach, and had the same odour. To 
this was probably to be traced the vivid redness of the mucous 
coat of the stomach, particularly about the pyloric orifice. 
I regret that the nervous and circulatory organs were not 
examined. 
CASE IV. 
A spaniel bitch, nine or ten years old, was brought to the in¬ 
firmary, with an ulcerated wound in the lower part of the chest. 
Tliis wound had existed two months, and no one knew the 
cause of it. Before its appearance the animal had enjoyed good 
health. During the first month the wound extended a little 
almost daily, and suppurated abundantly ; but the bitch did not 
appear to be much affected by it. She ate, drank, ran about as 
usual, and preserved her condition. After this she still retained 
her appetite, but began to lose flesh. Within the last three days 
the suppuration has rapidly diminished, the appetite has failed, 
she has begun to cough, and she was becoming more ra))idly thin. 
Present state. —She has, behind the elbow, and on the inferior 
and lateral part of the chest, a wound nearly four inches long and 
three wide. The integument is destroyed through the whole 
extent of it. The lint with which the wound is dressed is covered 
by a great quantity of pus, possessing little smell, and of a grey 
tint; few granulations can be seen, and the wound is ])alc and 
livid. The mucous membranes arc pale—res[)iratioii diliicult—•
