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 n. 
H.— 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 pig. 6G.— Cancer in the Eye. 
bones around the eye be- 
come diseased. As they become diseased, they also become 
enlarged, and have a very bad smell.
