CONTRIBUTION TO THE STUDY OF TI1E CHSNURUS CEREBRALIS. 
According to some authors, the almost exclusive seat of 
the taenia caenurus is the brain and the spina] cord, and the 
presence of this parasite in other organs is exceptional. Pro¬ 
fessor Rabe, of Hanover, reports several observations, among 
them one showing that this fact is not as uncommon as it is 
generally believed to be. 
He mentions one case of Zurn, who found a caenurus un¬ 
der the skin of a sheep, and one of Nathusius, who found it 
under that of a calf. Similar facts are not rare in the hare 
and the rabbit, or even in wild ruminants. Mr. Rabe has 
found the vesicles of this taenia in the nervous centers, but 
also in the lymphatic glands of the thorax and of the abdo¬ 
men, in the thyroid gland, and in the muscles of an antelope. 
In his view lymphatic glands and muscles would come next 
to the nervous center, among the organs where the caenurus 
is found.— Ibid. 
MELANO-SARCOMA IN THE CARDIAC MUSCLES. 
Mr. Koch has observed in a white horse melanotic tumors 
developed in the muscles of the heart. The largest, which 
had the dimensions of a large chicken’s egg, was protruding 
on the external face of the left ventricle. Another, the size of 
a large nut, was located in the interventricular septum, and 
formed a projection running towards the cavity of the left 
ventricle. Under the endocardium of the right heart, and 
on the septum also, near the valvular cordse-tendinosse of the 
auriculo-ventricular openings, were a number of smaller de¬ 
posits, varying in size from that of a grain of rice to that of 
an hazel nut. There was no cardiac disturbance during the 
life of the animal.— Ibid. 
CONTRIBUTION TO THE STUDY OF REPEATED COLICS IN 
THE HORSE. 
Repeated colics do not belong to a unique and well deter¬ 
mined morbid entity more than any other colics. They may 
arise from an intestinal stenosis, the pressure of a calculus, 
or peritoneal adhesions between the abdominal viscera. Mr.
