The Micro-organism of Dog Distemper [By M. G. 
Bisz]. —The author has searched in the spinal cord of a dog 
affected with paraplegia, the pathogeneous element described 
by Galli-Vaterio. By cultures and inoculations he has found a 
micro-organism which did not have all the specific characters of 
that of G. Vaterio, and he believes that this micro-organism of 
dog distemper has no constant biological characters.— -{/bid.) 
Researches upon the Most Common Causes of Ster¬ 
ility in Cows [By Mr. A. Fiorentini\. —These were made 
upon 50 uteri of cows, sold on account of sterility. In a third 
of those, the author found catarrhal endometritis with degenera¬ 
tion of the epithelium and proliferation of some points of the 
mucous, which had a warty appearance. The fluid contained 
m the uterine cavity contained a micro-organism, oval in form 
presenting some analogy with the B. coli. " It differs from it by 
giving yellow colonies, by liquefying gelatine and not being 
pathogenous to the guinea pig nor the rabbit. In the other 
organs, there were interstitial granular, septic, tuberculous 
metritis and cysts of the ovaries, of the uterus or of its neck. 
From these observations, the author believes that these vari¬ 
ous affections of the uterus can be avoided by repeated anti¬ 
septic washings of this cavity, during the days following parturi¬ 
tion^ In cows already diseased, which most all become nympho- 
maniacs, there would be advantage to perform castration, which 
would promote fattening and permit of sending them to the 
butcher in remunerative conditions.— {Giorn. Dello R. S. and

Feeding Animals with Flour of Cocoa. —The flour is 
made of dried cocoa-nuts. It is given in five times its weight of 
water, after soaking twelve hours. Dry flour cannot be digested. 
Administered wet, it is most economical and nutritive food, 
its nutritive power being beyond that of others, as demonstrated 
by the experiments of Prof. Zuchine. In horses cocoa-flour gives 
extraordinary results and can take the place of oats to some ex¬ 
tent. It ought to be given to horses in the evening—in colts, it 
promotes the development of muscles—in milk cows it increases 
the quantity of milk and of cream.— {Ibid.) 
Upon the Existing Power of Spores of Anthrax._ 
In the laboratory of Prof. Perroncito, with dried culture pre¬ 
pared in 1880, inoculations were made on guinea pigs, which
