CHAPTER VII. 

 DISEASES OF THE EAR AND EYE. 



I.— The Ear. 



DISEASES of the ear of the ox are very rarely met 

 with, and are similar to those of the horse. For any 

 information concerning them refer to this subject in 



Part II. 



II.— The Eye. 



1. Cancer. 



The eye of the ox seems to be a favorite place for can- 

 cers, which are very often met with. 



Causes.— The causes are the same as those of other 

 cancers, that is, the cancer germ gets into the blood, for the 

 disease first begins in the blood, but afterward locates and 

 shows itself in the eye. Some say it is the result of an injury. 



Symptoms. — The first 

 symptom is dullness of the 

 eye, with tears flowing from 

 the corners. There is a 

 bulging out, and if you look 

 closely you will see in the 

 back part of the eye a small 

 growth. The animal may 

 thrive fairly well for a while 

 but falls off in condition as 

 the growth develops, on ac- 

 count of the pain. Soon the 

 growth becomes so large 

 that it will destroy the 

 whole eye, which hangs 

 down on the cheek. It be- 

 comes very angry and red 

 looking, and bleeds freely if 

 the least thing touches it. 

 The cancer continues grow- 

 ing, and in a short time the 

 bones around the eye be- 

 come diseased. As they become diseased, they also become 

 enlarged, and. haye a very bad smell, 



Cancer in the Eye.
