EXTRACTS FROM EXCHANGES. 
437 
years, Mr. P. has not been called upon to make many post¬ 
mortems upon cats; but lately he has had the opportunity to 
follow three animals, and each one proved tuberculous. The 
lungs were found on post-mortem to be extensively consoli¬ 
dated, with almost the whole of the pulmonary tissues affected. 
The bronchial glands were more or less enlarged. In one of the 
animals tubercles were found on the abdominal viscera, the 
tubercle bacillus being present. Of course, these three cases 
may not be of positive value as a certain source of danger ; yet 
they seem to prove that feline tuberculosis may be more com¬ 
mon than is usually suspected. It is certain that more clinical 
observations and post-mortem examinations ought to be recorded 
and their history added to that already so rich of tuberculosis.

Tuberculosis of the Heart in a Cow [By Prof. Stock- 
man ].—The organ weighed 42^ pounds. The pericardium 
showed only a few recent tuberculous lesions; the epicardium, 
slightly altered, had its surface greatly raised by numerous 
tuberculous centres situated underneath in the walls of the 
heart. On section the organ was a mass of caseous matter, with 
many calcareous deposits. The inter muscular fibrous tissue 
was increased. Immediately around the cavities there was a 
narrow band of apparently sound muscular tissue. The cavities 
were, of course, much reduced in size. The valves were nor¬ 
mal ; the suprasternal lymphatic glands at the point of the 
pericardium, and the cardiac glands, offered an advanced caseous 
condition. The lungs contained no tuberculous lesions. The 
author believes in an infection through the lymphatic channels.

Extensive Disease of the Spleen in a Horse [By C. 
Dayus , M. R. C. V. S .].—A sixteen-year-old hunter was losing 
condition, and received a mild dose of physic, with a little tonic 
medicine. Although his appetite remained fair, he kept gradu¬ 
ally growing worse. After some time, suspecting some organic 
affection, in his attempts to make a diagnosis, careful examina¬ 
tion by the rectum revealed the presence in the left hypochon¬ 
driac region of a hard substance, which was supposed to be a 
mesenteric tumor, although the animal never manifested colicy 
pains. There was considerable tenderness over the spot on ex¬ 
ternal pressure being applied, and the animal moved very stiffly 
on that side. The horse was destroyed, and at the post-mortem 
it was found that “ the tumor was a greatly enlarged and exten¬ 
sively diseased spleen, which weighed exactly twenty pounds.”
