186 DISEASES OF THE HOG. 
tacked with hydrophobia in consequence of having 
wiped their mouths with linen which had been 
impregnated with the saliva of a mad dog; and a 
case is mentioned in which the disease originated 
from an attempt to untie with the teeth a knot ina 
cord by which one of these diseased animals had 
been fastened. Horses, oxen, sheep and other ani- 
mals are said to have contracted the disease by 
eating the straw upon which mad dogs have lain. ° 
We should therefore be. very careful if any ani- 
mal should have an attack of hydrophobia to be 
on the lookout in handling an animal or anything 
which it may have come in contact with, in case 
that any of the poison should touch any abraded 
surface or mucous membrane. A great many per- 
sons who are bitten are never attacked with the 
disease. It is possible that some systems are not . 
susceptible to the poison. It is said that some ani- 
mals are more poisonous than others. In man or 
animals that are bitten by the wolf a much larger 
portion is attacked than in those bitten by the dog; 
this is, however, explained by asserted facts that 
the wolf generally flies at the naked part, as the

through the clothing and in this way the teeth 
may be wiped off before reaching the skin, and the 
hair of animals may to a certain extent do the 
same, but the percentage of deaths of animals 
bitten by the same dog is much greater than that 
of man; of one hundred and fourteen cases of per- - 
sons bitten by mad wolves, collected by Dr. Wat- 
son, sixty-seven died; while of fifteen persons bit-
