parts of the brain infected 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 virulent as that from 
a case of the furious form. Dogs affected with dumb rabies are less 
dangerous simply because they are unable to bite and thus to infect 
others. 
Dumb and furious rabies do not always represent two distinct types 
of disease. The typical cases belong to the two extremes of symp- 
toms and there are always gradations between them. In fact, almost

every case 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 later. 
Again, a dog does not necessarily bite everything about it even if it 
has rabies and its jaws are not paralyzed. It may be combative and 
furious all of the time or only part of the time, or not at all. There is 
perhaps no other disease in which the symptoms may vary more than 
in rabies of the dog. 
Furious rabies. The symptoms appear very gradually. The 
animal’s habits and behavior are changed. It may be more restless 
or affectionate than usual, seeking to benear its master, fawning, lick-. 
ing the hand or face, and apparently, seeking sympathy and assist- 
ance. Such caresses are, however, extremely dangerous, for the ani- 
mal’s tongue, moist with virulent saliva, coming in contact with a part
