Introductory. Hydrophobia is an infectious disease which 

 in nature occurs epidemically chiefly among the carnivora, 

 especially in the dog and the wolf. Infection is carried by 

 the bite of a rabid animal or by a wound or abrasion being 

 licked by such. The disease can be transferred to other 

 species, and when once started can be spread from in- 

 dividual to individual by the same paths of infection. 

 Thus it occurs epidemically from time to time in cattle, 

 sheep, horses, and deer, and can be communicated to man; 

 but in modern times at least, infection practically never 

 takes place from man to man, though such an occurrence 

 is quite possible. 



In Western Europe the disease is most frequently 

 observed in the dog ; but in Eastern Europe, especially in 

 Russia, epidemics among wolves constitute a serious 

 danger both to other animals and to man. All the mani- 

 festations of the disease point to a serious affection of the 

 nervous system ; but inasmuch as symptoms of excitement 

 or of depression may predominate, it is customary to describe 

 clinically two varieties of rabies, (r) rabies proper, or furious 

 rabies (la rage vraie, la rage furieuse : die rasende Wutli) ; 

 and (2) dumb madness or paralytic rabies (la rage mite : die
