CHAPTER 11. 



ON THE 



CAUSES OF IMPERFECT SIGHT. 



Diseases of the eye in horses are so frequent 

 as ahnost to sanction a hcHef that he is natu- 

 rally more sul^jcct to this infirmity than any 

 other animal. But, if we consider the confine- 

 ment to which he is suhjected in hot and dark 

 stables, the constant costiveness produced by 

 drv food, and the o-eneral deranoement of tlie 

 system by violent and excessive exertions, it 

 will not appear extraordinary that blindness so 

 frequently occurs. 



In order to give a proper explanation of the 

 various diseases incident to the eye, it will be 

 necessary to enter into an anatomical descrip- 

 tion of that organ. 



The eye is placed sidewaj's in the head of 

 the horse, as well as in all other animals mIio 

 preserve themselves from danger by flight.
