PRACTICE OF VETERINARY MEDICINE.

diaphragm, around the matrix of the right kidney, and around 
the trachea, just where it passed into the chest. On separating 
the head from the neck for the purpose of carefully removing and 
dissecting the brain, I cut upon another large deposit of pus, which 
existed in the guttural pouches. The pus in these pouches differed 
somewhat from that liberated in the above-named parts; it was 
more dense, and appeared to consist of coarse grain-like portions : 
in the other parts it was of the consistence of thick cream ; in the 
latter locality it had lost its fluidity, and 1 had to remove it from 
the pouches with an old spoon. The mucous membrane of the 
pouches was much thickened; the greater portion of its surface 
was very white in colour, while other portions of it presented 
patches of vivid red, of about the size of a crown piece. 
Muscular System .—The muscles of animal life were moderately 
firm ; their colour was good, exhibiting, in fact, a state of fresh¬ 
ness which I scarcely expected. 
Digestive Organs .—The stomach around where the pus was 
deposited was greatly thickened, and its muscular structure soft¬ 
ened; internally it was very pale, both over its cuticular and mu¬ 
cous surfaces : it contained about four pounds weight of food in a 
dry state; it was, in fact, formed into a kind of ball, from which 
the stomach could be withdrawn perfectly clean. The small intes¬ 
tines were all more or less inflamed; the mucous membrane in 
many places displayed large patches of gangrene. The inflammation 
appeared to have been the most intense at the anterior extremity 
of the jejunum, in the middle of the jejunum, and along the greater 
portion of the ileum. The coecum also exhibited effects of disease : 
its coats were considerably thickened, and in a state of gangrene ; 
they lacerated with very little force; and the whole of its internal 
membrane was of a dark dull red colour; as also was the same 
membrane, here and there, of the small intestines. The same ap¬ 
pearances were again presented by the large bowels; patches of 
gangrene, common alike to the serous, muscular, and mucous tissues, 
and blended with other patches of the dull red colour above named. 
The omentum and mesentery were highly inflamed, and the cavity 
of the abdomen contained about two gallons of dirty green-coloured 
fluid, in which floated a small portion or two of lymph. The cel¬ 
lular tissue around the coecum, the stomach, the right kidney, the 
liver, and the trachea, where the pus had been deposited, was also 
much increased, I think, in quantity, but at any rate, most cer¬ 
tainly, in thickness; it appeared, in short, more like fibrous tissue 
than areolar. The liver presented the granular state so common to 
this viscus, and its capsule readily peeled away. The spleen was 
healthy, and contained but very little blood. 
Urinary Organs .—The bladder was empty ; its mucous mem-
