CONTAGIOUS DISEASES OF DOGS. 519 



of the face were agitated by various spasmodic contractions; his 

 eyeballs glazed and seemed ready to start from their sockets, and 

 at the moment, when crying out in agonizing tone, 'Do you not 

 see that black dog?' his countenance and attitude exhibited the 

 most dreadful picture of complicated horror, distress, and rage 

 that words could describe or imagination paint." 



Hydrophobia in the horse is similar to that of the dog, with 

 the exception that the remissions and paroxysms are less apparent 

 in the horse. The dog seems, for a time, to be almost freed from 

 the disease, but in the horse the absence of anxiety, restlessness, 

 and exhaustion is of much shorter duration, and the fits of vio- 

 lence more violent and prolonged, killing the animal on the 

 second or third day. The sexual desire is increased in the mare 

 and horse during the course of the disease. 



The symptoms of ral)ies in the cow, sheep, pig, goat, rabbit, 

 ^and cat are very similar to those in the dog. In the cow there is 

 paralysis of the hind extremities, before death, as in the horse. 



Post-mortem appearances of a dog affected vvuth raViies show 

 a paralysis of the lower jaw, a discoloration and swollen condi- 

 tion of the tongue, which hangs from the mouth, with super- 

 fluous blood in the outer inferior part. The color varies from a 

 dark red to a dingy purple, or almost black. The fauces situated 

 at the posterior part of the mouth generally exhibit traces of 

 inflammation. A strange post-mortem exhibit is the presence of 

 indigestible matter, probably small in quantity, in the back part 

 of the mouth. This indicates the depraved appetite and loss of 

 power in the muscles of the pharynx. The epiglottis is more or 

 less injected in every case of rabies. The edges of the glottis 

 show inflammation. The stomach and its organs may contain a 

 strange mass of hair, hay, straw, earth, horse fn?ccSj etc. There 

 is a peculiar inflammation of the stomach. It is more intense on 

 the summits or folds of the stomach. Well-marked extravasation 

 of blood or diffused inflammation is seen throughout the stomach 

 and bowels. The liver, spleen, kidney, and muscular system are 

 congested. No conclusions can be drawn from the lesions of the
