rarer and rarer, but which, throughout the course 

 of the disease, are increased in violence by the 

 sight of another dog. Finally the paralytic condi- 

 tion becomes complete and the animal's sufferings 

 are ended by death. 



Dumb Rabies 



Dumb rabies is distinguished from the furious 

 type by the early onset of the paralytic symptoms 

 and the absence of the desire to bite unless greatly 

 aggravated. The patient early becomes dull and 

 listless and often appears to have some slight dif- 

 ficulty in swallowing; anorexia is always present. 

 It is in cases of dumb rabies that the veterinarian 

 needs to use much caution when called upon to ex- 

 amine an arlimal that is supposed to have a "bone 

 in its throat." The paralysis of the lower jaw takes 

 place quite early in the course of the disease and 

 is rapidly followed by the general paralytic con- 

 dition described above, death usually taking place 

 about the third day. 



Treatment. — The disease being quite unamenable 

 to therapeutic measures, any treatment is useless* 

 in either the furious or the dumb forms, but val- 

 uable animals may be saved before symptoms have 

 developed if given the Pasteur treatment as soon 

 as possible after being bitten by a rabid animal. 



Tetanus 



Tetanus is a specific infective disease, character- 

 ized by tonic muscular spasms and caused by the 

 Bacillus tetani. The spores of the Bacillus tetani 

 are ubiquitous and gain entrance to the animal's
