 subdued manner, which changes to a wild look, and a desire to hide, 

 snapping when poked with a stick, terrible thirst, and inability, to 



, swallow. (See Fig. 1407.) If shut up 

 in a room, the dog will walk round and 

 round, looking up occasionally, as if 

 wishing, to get out ; if let out, .will bite 

 or snap at anything that comes in his, 

 way, and howl dismally. 



Whenever a dog, is bitten by another 

 dog, or by any other animal, whether

 terize it with nitrate of silver.

 worms engendered in the body of the dog effect their entrance, in the 

 shape of larvae, into the intestines of thousands upon thousands of 

 our most valuable sheep, carrying off yearly fearful ^numbers of 

 them. Nor is this all. Multitudes of human beings are affected by 

 the hydatid tumors of the liver, tracing their source directly to our 

 good friend and faithful servant, the dog. As an instance of the 

 ravages produced by parasites, Leuckart, speaking of the malignant 

 enteritis, with the production of false membranes, which trichinae
