CONTAGIOUS DISEASES OF DOGS. 517 



periods of excitement there is great prostration, the exhausted 

 animal lying down in the quietest spot it can find, insensible to 

 all surrounding objects, until, all at once, he springs up greatly 

 agitated. 



The bark of a rabid dog is husky, spasmodic, and more in the 

 natui'e of a howl. The jaw drops, exposing the tongue, which is 

 dry, and the bronchial membrane is of a brownish hue. If the 

 dog be spoken to by his master he will be recalled from watching 

 the motes flying in the air or the insects on the wall. Dispersed 

 by the magic influence of his master's voice, every object of terror 

 disai)pears, and he crawls toward him with the old expression of 

 attachment. A moment of quietude comes, the eyes slowly close, 

 the head drops, and the fore feet seem to be giving away, as if 

 he would fall; l)ut with renewed paroxysm he springs up again, 

 gazes wildly around, barks, snaps, and rushes to the extent of his 

 chain. The dog loses the power of swallowing, owing to the 

 spasmodic contraction of the throat. The animal does not dread

 and make eftort to drink. A mad dog, when loose, will travel a 

 great distance in a short time, finally endeavoring to return 

 home, generally rushing at everything in its way, but preferring

 bowels are constipated, tlie jmlse accelerated, the gait is un- 

 steady, the tail drops, the head is depressed, the nose protruded, 

 and the scent, sight, and hearing are much impaired. The dog 

 frequently vomits, and ultimately dies from coma, exhaustion, 

 and suffocaticin. Tlic i'nl)i(l (]nix, when loose, travels with his tail 

 depressed, and seemingly half unconscious of surrounding ob- 

 jects, llis open mouth, ])rntruded and black tongue, and rolling-

 period of rabies, a person accustomed to dogs will detect the 

 existence of the disease. The animal runs as if in pursuit of 

 imaginary ol>jects. The countenance changes, with alternating 

 brightness, and he wags his tail as though some pleasing vision
