gitis of the legs ; with all an infections odor of the faeces. Yet 
the ulcers of the leg were not those of farcy, they were not in¬ 
durated, and, again, while these symptoms were severe with the 
horses that worked, the three that were isolated were improving. 
With them the rations had been changed ; instead^ of oats, they 
received grass at will. Was that the cause of the improvement? 
Another inqniry into the quality of the oats revealed the fact 
that they contained a large quantity of little black seeds, those 
of liipinoiLS albus. With simple hygienic measures everything 
returned to its normal condition. A second injection of malleine 
made for acquit de conscience remained without effect.— {Rev.

ENGLISH REVIEW. 
Enlargement of the Prostate Treated by Castra¬ 
tion. —This mode of treatment, which seems to gradually make its 
Avay in the domain of veterinary surgery, has been applied by Mr. 
F. Hobday, of the Royal Veterinary College of London, in two 
cases with complete success. In the first case perfect recovery was 
obtained in 13 days ; in the second a decided improvement was 
noticed the second day following the operation, radical recovery 
occurring also in 13 days. The ordinary symptoms of the dis¬ 
ease are strangury, a peculiar gait of the hind legs, inability to 
walk more than a short distance, difffcnlty in rising after sitting 
down, with the presence at rectal examinations of the enlarge¬ 
ment of the glands. Both animals were operated upon with 
antiseptic cares and seemed not to be the worse by their mutila¬ 
tion .—{Journal of Comp. Pathol, and Therap.) 
“ X Rays ” in Canine Surgery. —The application of this 
comparatively recent discovery in photography has received 
more attention, we believe, at the hands of English veterinarians 
than with other practitioners. Mr. F. Hobday records two cases, 
illustrating its advantages in two cases of fractnres.^ The first 
was that of a collie dog, which, after jumping some high palings, 
had become very lame in the left foreleg. When brought to 
the author the dog had a good deal of swelling, heat and pain 
on the carpus, which were dne to the application of liniment. 
These subsided by treatment, but the lameness remained. Sus¬ 
pecting a fracture, the leg was skiographed, and, after an ex¬ 
posure of three minutes, a fracture of-the third metacarpal was 
made very plain. Crepitation conld not be made out, even after 
the seat of the fracture was known. The leg was placed in
