NEW METHOD FOR APPLYING THE RABIES TEST.

cause of partial or complete paralysis of the vocal cords. The 
animal may lie in this condition from one to three days and 
often more, before death ensues. 
In order to show the comparative value of the two methods 
as regards the period'of incubation and the duration of the dis¬ 
ease, Table I is appended. It shows that in most cases the rab¬ 
bits inoculated by each method exhibited symptoms of rabies at 
about the same time, or that, as would be expected, the incu¬ 
bation period is about the same in the two methods. 
In the cases of rabbits Nos. 343 and 346, inoculated supra- 
cerebrally with virus from dogs Nos. 70 and 71, respectively, it 
will be noticed that they failed to die of rabies even after hav¬ 
ing shown symptoms simultaneously with Nos. 340, 341 and 
342, which were inoculated with virus from dog No. 70 also, 
and which died of rabies in 16, 21 and 26 days respectively, and 
with Nos. 344, 345 and 347, which were inoculated with virus 
from dog No. 71, and which died of rabies in 14, 17 and 14 days
