Koch dissolves them out; he presses out moist bacilli ; Koch % 
dissolves out the contents of dried bacilli; both utilize the : 
principle of trituration, however, in getting out the bacillary j 
contents.— {Berl. Thicrarzt. WocJi.') y : 
Brain Abscess in the Horse. —R. was called in to see ^ j 
a horse that ostensibly had been suffering from pneumonia for - ’ 
a week or so. Four clays later meningitis was diagnosticated, ■ 
and ten days later R. narrowed down his diagnosis to an abscess of y 
the brain, situated in the posterior portion of the left lobe and 
near the surface of the brain, from the fact that there was c ^; 
blindness of the right eye. R. threw the horse, opened the skull 
by making an incision 5 c. m. long, but failed to localize the • i 
presumptive abscess. One week later he had the horse killed, 
and at the autopsy found the left lobe larger than the right and 
the pia mater congested. Just a few m. m. back of the posterior 
end of his former incision he detected a yellowish red area 
unconvoluted, strongly adherent, which yielded 32 g. of pus ■ 
on incision. He failed to find the abscess during life merely 
because he hadn’t made a big enough incision.— {Berl. Thiei^arzt.

Hyper.fmia of the Spleen in Sheep as a Means 
OF Diagnosis of Forced Fattening of Animals Before 
Slaughter. —P. asserts that one finds the spleen enlarged to 
twice or thrice its natural size in sheep that were fattened be- - 
fore slaughter by an excess of drink or feed, without there being h- 
any other visceral changes noticeable. Such being the case, we 
have undoubtedly to deal with a physiological hypersemia here ' c. 
which may not necessarily mean a pathologial condition ; but 
it must be admitted that the meat of such sheep is redder in x 
color and does not look as healthy as it should.— [Berl. Thierarzt. A

ENGLISH REVIEW. 
Follicular Mange \By Xi\ —In a concise article in the 
Veterinary Joninial., the author lays down the following facts : - 
It seems that the disease due to the demodexfollicnloritni is.get¬ 
ting more common, the contagious nature of the disease, though 
not very great, may be a cause of it ; the diagnosis of the dis- ^ 
ease is very simple and ought to be made early ; the symptoms p 
consist principally in the appearance of the disease about the > : 
head first, then spreading to the fore legs and feet, and the sides, -4 
to become generalized to the rest of the'body ; there is no pru- p
