DISEASES OF THE NERVOUS SYSTEM. 245 



frequently proceeds from wounds of the tongue or mouth, 

 than from any morbid condition of the stomach. 



Lastly, when a dog unconfined becomes rabid, there is 

 mush that is characteristic in his mode of travelling. His 

 gait may be termed a rambling, or jog-trot. The heaa is car- 

 ried low, the tongue protrudes from the side of the mouth, or 

 hangs pendent in front, swollen and covered with dirt. It is 

 rare he turns from his path to attack any thing (unless be 

 an animal of the same species, to which they invariably show 

 the greatest animosity), but woe betide any one who attempts 

 to stay his onward course. This pace is continued with little 

 intermission until exhaustion overtakes him, or it may be a 

 fit, when he creeps into an obscure place, and lies in a fatigued 

 or comatose state for hours. 



Such then, as I have endeavored clearly to describe them, 

 are the leading symptoms of this horrible malady. 



Tranquil or Dumb Madness. — The general symptoms in 

 this form of rabies are much the same as in the preceding, 

 with the exception of absence of voice, modification of ner- 

 vous excitability, and paralysis of the muscles of the lower 

 jaw. The latter is a curious and characteristic feature in this 

 type of the malady. As I observed in " Land and Water " 

 with regaird to the Albrighton hounds, " No particular period 

 can be given at which this symptom is observed. One at 

 feeding time had refused its food, and in three hours after its 

 jaw'had dropped ; another, apparently well at night, was found 

 similarly affected the following morning, and, in fact, in 

 many of them this paralysis was noticed before any other 

 symptom." 



Frequently in packs of hounds the two forms of rabies 

 exhibit themselves simultaneously, and as iiioculation from 

 glanders produces farcy, and vice versa, so ferocious madness 

 may give rise to the dumb or furious form. 



Maternal affection is not interfered with.*

 bid as it is in the healthy dog. m! Defays, a professor at the Brussels
