jlack three-year-old colt upon which numerous hairless patches 
existed. Those were supposed to be due to want of care during 
i severe winter. At first this horse was in good condition, but 
5oon lost flesh and was ultimately taken from the herd and 
destroyed. The 196 diseased presented lesions which permitted 
to divide them into three groups, according to the severity of the 
lesions. The 92 of the first group had on the throat, neck, 
chest, shoulders, loins and flanks wide hairless patches as large 
as a soup plate. In six of them, the trunk was entirely hair¬ 
less, all the diseased parts were covered with blackish crusts, 
adhering quite firmly to the skin, and with greyish scabs easily 
removed. Under them, the skin was dry; seldom moist with a 
little serosity. There was no exaggeration of sensibility of the 
skin nor any itching. I11 the second group, there were 74 horses. 
The patches had an annular shape, as large as a rouble (a silver 
dollar); some, however, as wide as the hand. They were cov¬ 
ered with a white-greyish substance, and the few hairs remain¬ 
ing in the centre looked as if the patches had been clipped. On 
their circumference there were red spots or small vesicles filled 
with liquid ; the hairs were easily pulled away and the hair 
bulbs appeared then covered with a fine greyish powder. The 
30 horses of the last group had no hairless patches, but the head, 
neck and flanks were covered with red spots varying in size from 
that of a small lens to that of a five-cent piece, and also with 
very small vesicles filled with fluid. All the animals were affected. 
The lesions were more marked on dark colored individuals than 
in those with light coat. The articulated threads and free spores 
of the trichophyton tonsurans found with the microscope con¬ 
firmed the diagnosis made by the author. The treatment con¬ 
sisted of washings with warm water, followed by repeated appli¬ 
cations of an ointment made of green soap and creolin. The 
disease did not affect the men who took charge of the animals, 
although they took no precautions against infection.— {Archin.

Operation for Ventrae Hernia [By Malinovsky ].—A 
20-year-old horse received a severe bruise on the left inguinal 
region, which was followed by the formation of a swelling as 
big as two fists, soft, and slightly painful. Reduced by pressure, 
a small opening through the abdominal walls was readily dis¬ 
covered. The next day the tumor had considerably increased, 
was painful and irreducible. Fearing strangulation, the author 
decided to operate. The skin, three times the normal thickness, 
was incised, and the protruding small intestine was exposed. It
