attention was not fastened upon the same, it proceeded unin¬

Ruminatio humana is not to be confounded with that of 
animals, which is a physiological action.— Deut. Med. Ztg.

EXPERIMENTAL IMMUNITY AGAINST INFLUENZA. 
Dr. Bruschettini has made exhaustive trials upon the activity 
of the influenza bacillus, and finds that the living cultures upon 
bouillon or agar-agar, when intratracheally injected, have but a 
slight pathological activity; this is not the case, however, when 
the microbe is propagated upon blood, its virulence is well . 
marked. 
The best material, and that which imparts the greatest 
degree of immunity, is the latter blood culture after it has been 
filtered throngh the Berkfeld apparatus. This serum possesses 
a strong anticoxic power, but does not destroy the bacteria. 
The serum of animals so vaccinated, when injected into others, 
imparts its quality to them, and guarantees an immunity from 
the affection. 
This liquid also has the power of transmitting a curative 
effect, in as such as rabbits may be saved from death by its 
application.— D. Med. Wochcnschrift , 33, ’pj\ 
VALUE OF INJECTIONS OF MALLEIN IN THE DETECTION OF LATENT 
GLANDERS. 
For some time the Urban Axle Company of Paris has 
sustained great loss from the existence of an endemic state of 
glanders in their stables. Despite the fact that every suspected 
horse was immediately killed, and that its neighbors were 
isolated, the endemic was fed by latent cases. How were these 
to be detected? The required test appears to have been dis¬ 
covered in mallein. The employment in subcutaneous injections 
on 4,450 horses was followed in 562 instances by the character¬ 
istic rise in temperature. These 562 animals were slaughtered,
