Atrophy of the Semimembranosis After Castration 
[By J. Monsarrat]. —Having a horse to castrate the author 
threw and secured him in the ordinary way, but had a great 
deal of difficulty in bringing the right hind leg on to the shoul¬ 
der, on account of the stiff condition in which the horse held 
the leg. The operation was successful and the cicatrization 
was complete in fifteen days. Two months later, however, 
the very marked emaciation of the semimembranosis was called 
to his attention. No treatment was applied, exercise only pre¬ 
scribed. The muscle returned slowly to its normal size, but it 
required several months for it. This is a peculiar complication 
of the positions in which animals to be castrated are sometimes 
submitted, and to avoid it the author recommends the dorsal 
decubitus, which is already resorted to by many veterinarians.

A Case of Poee-Evie in the Horse [By A. Morey].— 
This horse had a fall in which his head struck heavily on the 
ground, leaving at that time only a slight excoriation, which 
healed rapidly, but was followed by the appearance of a large 
soft tumor. The horse was notwithstanding kept to work, 
and it was after he had several attacks of vertigo and partial 
loss of motion that the owner asked for advice. The swelling 
was evidently purulent and was allowed to escape by a free in¬ 
cision. To explore the cavity of the abscess it was necessary to 
cast the patient, and on examining, extensive necrosis was de¬ 
tected, with a loose piece of the occipital bone floating in it, 
and, rough and irregular, it measured some twenty-one centi¬ 
metres square. Free counter openings, frequent washings with 
solution of sublimate, 1-1000, allowed the animal to resume 
work in less than three weeks.— (Journ. de Med. Vet. and

Cutaneous Papieeomas in a Heifer [By M. Mathin ]. 
—When this heifer was brought to the attention of the author 
both fore legs were terribly affected. On the left, the tumors 
occupied the posterior and lateral parts of the knee, of the ten¬ 
dons and of the cannon ; forming a mass of horny papillse of 
various sizes, with here and there pedicles, giving in some 
places the appearance of an artichoke, in others that of a chry-
