EXTRACTS FROM EXCHANGES.

275 cubic centimeters of fluid. The minute microscopical ex¬ 
amination of the liquid and of the walls of the cyst excluded 
the supposition of its being a cyst of echinococci, and showed 
it to be an anomaly of formation—that is, a congenital serous 
cyst. In the second case, some fifty cysts were found in the 
abdominal cavity, attached to the omentum and to the serous 
covering of the rumen. Some were spherical in shape, others 
piriform. They contained a perfectly limpid fluid ; some were 
pedunculated, others spread over the walls of the organs. At 
first they were thought to be parasitic cysts, but no indications 
of echinococci could be found, and the conclusion was that they 
were the result of a cystic peritonitis, without gravity, and per¬ 
fectly local. The third case, also not due to echinococci, was a 
transparent growth on the tricuspid valve of a calf. It was 
ovoid in shape, measured two centimeters in diameter, and con¬ 
tained a slightly straw-colored liquid. The presence of these 
three cysts and their nature, which differs from the usual para¬ 
sitic nature, renders this communication interesting to veteri¬ 
narians who have charge of meat inspection at slaughter-houses.

Laceration of the Gravid Uterus Without Lesion 
of THE Abdominau Waeu [G. Dronet\. — These injuries are 
somewhat frequent in domestic females toward the time of 
parturition, because of rough or improper manipulations. They 
may also occur in connection with deep wounds of the abdomen, 
and, again, although rarely, from traumas of the abdominal 
wall, bruises, etc. Their prognosis is generally fatal. The 
author reports the result of an examination made at a slaughter¬ 
house upon the carcass of a ewe just killed, and in which an ex¬ 
tra-uterine foetus was found floating freely in the abdomen. 
The foetus seemed to be in about its fourth or fifth month of de¬ 
velopment, and weighed 1500 grammes. It formed an irregular 
mass, with both fore legs stretched forward along the neck and 
head, the hind legs flexed under the abdomen ; it had no ad¬ 
herence to the abdominal walls, was floating freely, and united 
by little connective tissue bands to the intestines. When dis¬ 
sected its organs were found to be healthy, without odor or de-
