Deafness. 



The beautiful play of the ears has ceased, and the 

 horse hears not the voice of his master. Much of the 

 apparent stupidity of some horses is attributable to their 

 imperfect hearing. It occasionally appears to follow the 

 decline of various diseases, and especially of those that 

 affect the head and the respiratory passages. It has 

 been the consequence of brutal treatment, closing the 

 condiut of the ear, or rupturing the tympanum ; and it 

 is certainly as in other animals, the accompaniment of old 

 age. In the present state of veterinary knowledge, it is 

 an incurable complaint ; the only thing that can be done 

 is, not to punish the poor slave for his apparent stupidity, 

 produced perhaps by over exertion in the service of his 

 master. 



Iidcked Jaw, or Tetanus. 



This disease has a two-fold origin, the one is caused 

 by wounds, and the other has no apparent cause, but is 

 supposed to be symptomatic of some constitutional causes, 

 as intestinal irritation from parasitic animals. Both 

 varieties are denominated tranmatic and idiophaticy in 

 technical phraseology.
