reference to the location and extent of the bites. If the indi- 

 vidual is bitten about the head the period of incubation is 

 much shorter than if the injuries are on the extremities. 



In the dog, the period of incubation in 144 cases was 

 clearly determined by Peuch. His table with the addition of 

 percentages is appended.

The somewhat popular opinion that most of the cases of 

 rabies occur in the summer, especially in "dog days," is not 

 founded upon facts. Rabid dogs are nearly if not quite as 

 numerous in winter and early spring as in summer. Salmon 

 has collected 14,066 cases of rabies in dogs with the months 

 in which the disease occurred. The results are exceedingly 

 interesting as the appended table shows.
