PARASITES OF THE SARCOMA. 
By Richard Middleton, D. V. S., Philadelphia, Pa. 
The author has in the last year written upon the small bodies 
found in the intima of cancer cells, which he considers of para¬ 
sitic origin. His latest effort, in four cases of cancer of the 
mammae, has permitted him to positively detect their animal 
nature. 
They consist of a very small body, which in the first stage 
of development is surrounded by a protoplasmic envelope, all of 
which is enclosed in a capsule. As the development progresses, 
the protoplasm gradually becomes less and less ; the body con¬ 
tinues to acquire dimensions, until finally it ruptures and dis¬ 
charges numerous round refractory globules. 
In its primitive state the parasite takes kindly to haematoxy- 
lin, while in its maturer condition it yields only to eosin and ani¬ 
line orange. According to its structure and history of de¬ 
velopment, this microbe appears to belong to the class of cocci. 
At the close of his article the author mentions an easy 
method of discovering the coccus by means of the staining com¬ 
binations. The section of cancerous material, cut very thin, is 
hardened, and colored with a mixture of saffron and haematoxy- 
lin, coming after this in a solution of anilin orange. By this 
procedure the nucleus assumes the saffron, the protoplasm the 
orange, and the body of the parasite the haematoxylin .—Deutsche

PELVIC ABSCESS. 
Ber examined a I y 2 year old calf which had suffered for 
some time past with constipation and loss of appetite, and, re¬ 
markable to state, the rumination was not influenced by the in¬ 
disposition. After two weeks of these troubles they suddenly 
disappeared; later, however, the same symptoms reappeared, 
and with them a swelling which protruded at the left side of the 
anus, completely occluding the rectum.
