PREVENTIVE INOCULATION AGAINST ANTHRAX AND SWINE PLAGUE 
IN HUNGARY. 
A report issued by the Hungarian Minister of Agriculture 
with regard to the operations of Pasteur, Chamberland Labora¬ 
tory shows that in 1892 806,932 animals were protectively 
inoculated, or nearly 200,000 more than in the preceding 
year. Since its institution in 1886, this laboratory has supplied 
material sufficent to inoculate 1,237,674 pigs, and so to protect 
them against swine plague; while enough has been furnished to 
inoculate 1,122,558 horses, cattle, sheep, etc., against anthrax.

EXPERIMENTAL IMMUNITY AGAINST INFUENZA. 
Bruschettini {Rif. Med. July 16, 1893) returns once more to 
this subject. In previous papers he demonstrated a pathogenic 
action of the B influenzae on animals. He found the rabbit very 
sensitive to this infection, and was able to ascertain conditions 
under which this animal could be infected at will, either with a 
slight transitory affection or with a grave fatal disease. He 
showed that these two types corresponded closely to the vary¬ 
ing forms of the disease in the human subject, both in clinical 
course and pathological effects. He next attacked the subject 
of artificial immunity, dividing his researches into three series. 
He sought first to vaccinate animals against the infection; 
having succeeded in this, he tried whether immunity could be 
conveyed from a vaccinated to an unvaccinated animal by injec¬ 
tions of the serum derived from the former; finally, with the 
serum he has tried not only to prevent, but to cure the already 
established disease. In all these points he has met with suc¬ 
cess, and his conclusions may be summarized as follows: (1)
