188 DISEASES OF THE HOG. 
be some stricture of the throat, as the animal 
seems to want to get something out of it and will 
even put its feet up to the corners of the mouth. 
The breathing is labored and has a peculiar sound, 
caused, no doubt, from the throat affection. As 
the disease advances the animal will become more 
excited, and if at liberty will run around, snap- 
ying at everything it meets and sometimes seems 
as if it were looking for something to attack. At 
length symptoms of paralysis set in, the legs give 
way, the lower jaw drops and the animal usually 
dies about the fourth or fifth day, although I have 
known them to die sooner. 
Treatment is of no use after the disease is once 
established, and the animal should be destroyed. 
If an animal is known to be bitten by a rabid ani- 
mal the parts should be washed and caustic potass 
applied; this is the best caustic because it will pen- 
eLvate-deeper into the wound than any other caus- 
tic. If none is at hand, take a red hot iron and 
burn the part as deep as possible. If this is well 
done it will save the animal’s life in every case.
