450 SARCOMA OVARII IN A COW. 
although nothing could be expected from it. On the following 
day F. Meyer introduced the trochar near the linea alba, 
about a hand’s breadth behind the umbilicus. This was fol- 
lowed by the escape of about six ounces of fluid, of a yellow 
reddish colour, in a very feeble stream, which soon ceased. The 
canula was then removed, and the trochar plunged in again 
about a foot more to the left. This was followed by a similar 
result. The conclusion thereupon was, that, if ascites was 
present, the fluid must be contained in a sac. (ascites saccatus.) 
The medical opinion was for slaughtering the cow, but even- 
tually she was sent back to the pasture. On the 14th of July, 
F. Meyer was informed that the cow had been ill ever since 
the operation, and had lost her appetite. On examination, the 
pulse was found beating at the heart, and respiration was the 
same as before the operation. The visible mucous membranes 
were paler, particularly the conjunctiva. The animal was very 
dull, and laid down a great deal. The diagnosis was peritonitis, 
and the cow was killed the same day. The dissection shewed 
the cellular tissue of the left hind leg to be the seat of the 
fluid extravasated. Tumour thicker and harder, while the 
small quantity of adipose matter was of a yellow colour. On 
opening the abdomen, about two stable-pailsful of dark red- 
coloured serum escaped, in which large clots of coagulated 
blood were found, weighing from three to four pounds each. 
The peritoneum shewed traces of inflammation, while an anor- 
mous irregularly shaped fleshy mass, covered by peritoneum, 
and unconnected with the abdominal muscles, partly of a dark 
and partly of a paler red colour, occupied such an extent of 
surface that neither stomach nor intestines were visible. 
To remove this extraordinary formation, which extended from 
the pelvis to the posterior part of the sternum, it became neces- 
sary to raise the posterior part of the carcass, and, after making 
a section at the uterus and rectum, this enormous mass rolled 
out: the stomach, bowels, and other abdominal organs, appearing 
along the spine, reduced to about one-third of their natural size, 
through the pressure of this extraordinary formation. On ex- 
amination it was found that the mass was the right ovarium. 
As it lay upon the ground, it measured four feet in length 
and three in breadth, and, on a section being made, one foot in 
diameter. Its weight was 250 pounds, Cologne. In the centre 
was a large cavity subdivided into innumerable compartments, 
filled with dark clotted blood, which was estimated at about 
one-third of the weight. The broad ligament of the uterus was 
somewhat longer on the right side than on the left. The 
ovarial branch of the internal spermatic artery, which supplied 
the tumour with blood, had acquired the size of a large goose-
