iting a hyperasthesia on application of the faradio current, 

 ■entitle to a favorable prognosis. 



Generally speaking, paralyses of the facial and radial 

 nerves are more favorable for a recovery than those of the 

 crural or suprascapular nerves. 



Treatment of Nerve Paralysis. 



What do you inainly strive at in the treatTnent of paralysis ? 



1. To relieve the injured nerve from the direct cause of 

 its paralysis. This is rarely possible, most nerves being 

 Tseyond reach. 



3, To keep up the nutrition of the paralyzed muscle. 



As long as the muscle reacts to the faradic or galvanic 

 current it is well to apply it. But most animals, and espe- 

 cially horses, soon become very unruly on the application of 

 electricity, and other agents have to be employed to prevent 

 atrophy as far as such is possible. The next best agent is per- 

 sistently applied massage, blisters, setons, hypodermic injec- 

 tions of strychnine and veratrine, saturated aqueous solution 

 ■of sodium chloride, or bichloride of mercury ; veratrine must 

 be used with care, as overdoses do not revive, but, on the 

 contrary, fatigue and paralyze muscles. 



Inflammation of a Nerve (Neuritis). 



What are the causes of neuritis ? 



Traumatisms, infection, toxic agents. 

 Js neuritis often seen in animals f 



It does not occur often, except certain forms of neuritis 

 of the eye. A great many authors claim that hemiplegia 

 laryngitis (roaring) is the result of neuritis of the recurrent 

 nerve, due to at first a pleurisy, the inflammation extending
