§ 372 Symptoms. Rabies is generally divided into 

 two forms, furious and dumb. In the first the animal is irri- 

 table aggressive and bites nearly every object which comes m 

 its wav • in the second the muscles of its jaws are paralyzed 

 almost from the beginning and being unable to bite the ani- 

 mal remains more quiet and tranquil. Essentially the two 

 forms of the disease are the same, but probably owing to the 

 parts of the brain attacked or the acuteness of the attack or 

 both, paralysis appears much sooner in the dumb form than in 

 the other The saliva from a case of dumb rabies is just as 

 dangerous and virulent as that from a case of furious rabies. 

 Dogs affected with dumb rabies are less dangerous simply be- 

 cause thev are unable to bite and thus to intect others. 



Dumb rabies and furious rabies do not always represent 

 two distinct tvpes of disease. The typical cases belong to the 

 twoextremes'ofsvmptoms and there are always graduations 

 between them. In fact, almost every ca.se of furious rabies 

 sooner or later changes to the dumb form, that is, the final 

 stage of the disease is almost invariably paralytic In the 

 typical development of the dumb form, the paralysis occurs on 

 the first day of the disease. It may not appear, however, 

 until the second or third or even a day later. 



A-ain, a dog does not necessarily bite everything about it 

 even iflt has rabies and its jaws are not paralyzed. It may be 

 combative and furious all of the time or only part of the tune.
