with improvement in three. One of his colleagues and friends, 
Mr. Garcin, has with the same operation obtained the following- 
results : Out of 50 operated, 9 were followed with complete suc¬ 
cess, aud, whether race, track, or work horses, were perfectly 
able to do their duties.— (Rec. de Med. Vet.) 
Treble Gestation in a Heifer [A. Fries '].—The author 
records the case of a heifer to which he was called because she 
was in labor. When he arrived he found the cow somewhat 
weak, with three calves about her. These were no bigger than 
an ordinary dog. The mother had delivered without trouble. 
The case is quite rare, especially with a primapara. The weight 
of each calf was 35, 33 and 36 pounds. They were in excel¬ 
lent condition and took heartily to the mother. The mother 
was treated only with tonics and good food.— (Rec. de Med. Vet.) 
Double Gestation in a Mare [M. Porchevel ].—These are 
rare in mares (1 in 1000, says Cornevin). The products are of 
the same or of different sexes. But they may also be of 
different species, if the mare has been covered by a stallion and 
afterwards by a jackass. A draught mare was covered by a 
stallion and later on the same day by a jackass. At term, she 
dropped two little fellows, a male mule and a filly. The twins 
were well formed, grew well and were well sold at the time of 
being weaned.— (Journ. de Med. Vet. and Zootech.) 
CHvSOPH agism in THE Cat [M. Rabieaux ].—Suddenly a 
cat cannot swallow solid food ; he takes easily the liquid poured 
in his mouth. An oesophageal probe reaches the cardial orifice, 
meets with a slight resistance and then enters the stomach. 
Kxploration of the throat and neck gives no positive result. 
Supposing cesophagism present, faradisation is resorted to. 
After three minutes of electrization of the neck, the animal suc¬ 
ceeds in swallowing a few pieces of meat. After a second 
seating, the cat takes his food alone and swallows it without 
trouble. The cure lasted fifteen days. After that lapse of time 
came nervous pneumonia with titubation, walking in circle, 
dropping on the floor, contraction of the legs. At the post¬ 
mortem was found a sewing needle, four centimeters long, im¬ 
planted in the walls of the stomach and plunging into the 
abdominal cavity. The cause of death, however, was purulent 
meningitis, which had no relation to the stomach trouble.—

Periodic Ophthalmia and Typhoid Fever [M. Vanney]. 
—A seven-year-old horse has typhoid fever with gastro-intestinal 
manifestations. At the same time occur the symptoms of an at-
