EXTRACTS FROM FOREIGN JOURNALS. 
times he had seemed furious, he had at others been only dull and 
morose. At intervals and by occasional accessions he had ex¬ 
hibited a desire to bite; had gnawed doors and other foreign 
bodies, and at last, had run away when his master attempted to 
approach him. 
In opening the abdomen, two tape-worms were discovered, 
one floating in the peritoneum, the other" engaged in a perfora¬ 
tion through the intestines, partly in the peritoneal cavity and 
partly retained in the intestines. The intestinal fistula through 
which they had passed was situated at a short distance from the 
stomach. The fistula had all the characters of being of some 
standing and certainly was not a post mortem lesion. The entire 
organism otherwise was in a perfectly healthy condition. 
To obviate any possible objections to the diagnosis established 
by the post mortem, the rachidian bulb was triturated in dis¬ 
tilled water, and the liquid filtered and an injection of it made on 
a dog and a rabbit; on the first, in the frontal region, on the 
second, in the anterior chamber of the eye. The dog died two 
days later of another disease, while the rabbit recovered from the

operation and was well two months after. Ibid..

By T. Mauri. 
After reviewing the theory of the usual presence in gray and 
white animals, and of the exceptional manifestation of the disease 
in horses of different colors, bay and black, and referring to a few 
cases where abnormalities of that nature have been recorded, the 
author describes the case of a chestnut bay mare, with white 
hairs on the body, aged six years, which was brought under his 
observation. The animal had first at the inferior face of the base 
of the tail, on the left side, a tumor of the size of a goose egg, 
bosselated, hard, painless, well defined, and of a well marked black 
color. Evidently it was a melanoma. The animal was operated 
on and recovered. An examination of the tumor by section 
demonstrated the correctness of the diagnosis. 
About a month later the animal was returned to Mr. Mauri, 
the growth having reappeared. It was larger and was surrounded
