cultures do not color after Grain’s method. Guinea pigs die 
after subcutaneous injections in from one to four days. The 
virulence of the bacillus remains for six months in satisfactory 
culture mediums. In all bovine species the disease can be pro¬ 
duced with the bacillus. Size of bacillus in fresh culture and 
blood of animals sick with the disease is 0.07 u, but after intro¬ 
duction into bodies of animals experimented upon shrinks in 
size to 0.03 u. At 45° C. they remain pyogenic and at 48° C, 
perish after 15 minutes. The bacillus is not always present in 
the saliva or mouth lesions. S. has tried to attenuate the bacil¬ 
lus for immunizing purposes.— (Berl. Thierdrzt Woch.) 
Another Germ Supposed to be the Specific Cause of 
Foot-and-Mouth Disease.—J. in opposition to S. claims 
that he has found the specific cause of foot-and-mouth disease. 
Whereas S. failed to find the germs in the contents of the 
apthous patches of the mouth where one would most expect to 
find it, owing to there being so many different germs that hind¬ 
ered him in finding it. J. sterilized the apthous patches and 
with a sterilized syringe withdrew their contents and found as 
he claims the germ therein. While S. claims that the germ is 
a bacillus, J. claims it to be a protozoa of class of coccidia with 
double contour and refracting capsule. Upon inoculating bo¬ 
vine species with apthous contents freed from coccidia no symp¬ 
toms of the disease occurred even after the lapse of twelve to 
fourteen days, but on inoculating the animals with the unfil¬ 
tered contents containing the coccidia, the disease invariably en¬ 
sued in from three to four days in all the animals inoculated. 
If this be so there are two distinct germs, that inoculated in 
bovine species can produce lesions of foot-and-mouth disease, 
one vegetable, a bacillus {Sarcovicci)^ the other animal, a protozoa, 
of class coccidia. Hence there can be no specificity in the germ 
of this disease and Koch’s theory of specificity of germs must go 
begging, for he maintains the specificity of germs, both as re¬ 
gard to their form and morphological characters in the produc¬ 
tion of disease.— {Berl. Thierdrzt Woch.')

Abscess of the Peevis and Poeyneuritis in a Mare.— 
As remarked by the author of this article. Prof. Rabat, of the 
Toulouse school, the question of polyneuritis is but little known 
in human and also in veterinary medicine, and on this account 
die case is of a double interest. It relates to a mare which, hav-
