EXTRACTS FROM GERMAN PERIODICALS.

by Nordheim, that of a horse having a pulse of fourteen per 
minute became unconscious several times during the day. 
Enlargement of the auricular-ventricular opening was the 
only lesion found post-mortem. 
A similar case was observed by Vogel, and is elaborated 
in Hering s “ Repertor.” of 1888 ; the horse had but one heart 
tone and a pulse of 15 to 19, likewise suffering from fainting 
spells. Hypertrophy of the left auricle and ventricle were 
discovered after death.— Mtsh. f. prakt . Thierheilk. 
TRANSMISSION OF MALADIE DU COIT IN CANIDiE. 
As is known, this affection is indigenous to the equine 
species, and after a course of several months of emaciations 
and paralytic symptoms leads to a fatal termination. 
The autopsy upon these animals shows invariable locali¬ 
ties of softening in the spinal cord. By inoculating the latter 
substance, the disease may be transmitted from one horse to 
another. 
Nocard was successful in producing the malady in dogs 
through injections of the same softening herds into the ante¬ 
rior chamber of the eye. These animals succumbed in from 
six to eleven weeks, the train of symptoms being precisely 
as in the horse. This same investigator found the contagion 
to be conservable in neutral gelatine.— Thier. Woch. 
BACTERIOLOGICAL STUDY OF BUTTER. 
Adopting the Lafar method of examination it is to be seen 
that the bacteria of butter are in no wise identical with those 
of milk. The residuary milk secured from the centrifugal 
separator is extraordinarily rich in its microbic constituents. 
Since the butter cannot be sterilized as milk may be, it se¬ 
quentially is to be premised that the former must needs con¬ 
tain numerous animate bacteria. Lafar finds the experiment 
to be variable, and their results to depend upon extraneous 
circumstances incidental to the commercial manipulation of 
the article.
