CHAPTER VI. 



DISEASES OF THE EAR AND EYE. 



Diseases of the ear of the ox are very rarely met with, and 

 are similar to those of the horse, and for any information contern- 

 ing them refer to diseases of the ear in the horse. 



CANCER IN THE EYE. 



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

 and is very often met with. 



Causes. — The causes of it are the same as other cancers, that 

 is, the cancer germs get into the blood, for the disease first begins 

 in the blood, but afterward locates and shows itself in the eye, 

 although some say it will come on from an injury. 



Symptoms. — The first symptom is dullness of the eye, with 

 tears flowing from the corners ; there will be a bulging out of the 

 eye, and if you look close you will see in the back part of the eye a 

 small growth ; the animal may thrive fairly well for a while, but 

 will fall off in condition as the growth comes on account of the 

 pain in the eye ; soon the growth gets so large that it will destroy 

 the whole eye and hang down on the cheek ; it gets very 

 angry and red looking, and will bleed freely if the least thing 

 touches it; the cancer keeps on growing, and in a short time th« 

 bones around the eye become diseased, and when they become dis 

 eased, they also become enlarged, and have a very bad smell. 



Treatment. — By removing the eye in the early stages of th* 

 disease you can effect a cure. This is done by throwing and 

 securing the animal ; have the head held solid, and with a knife 

 cut around the eye and loosen it from the eyelids, then stick a 

 small hook into the eye and pull it out as far as you can, then 

 take a piece of carriage trimmers' twine and slip it around the 

 back part of the eye and tie it tight — tliis will stop the bleeding — 

 then cut the eye off in front of where you tied the string ; saturate 

 a piece of cotton batting with Monsell's solution of iron and insert 

 it in the hole where the eye came out of; take the batting out the 

 next day and bathe the eye twice a day with luke warm water and 

 soap, after bathing apply white lotion ; if the parts are raw and 

 angry looking touch the spots with caustic potash every day. 

 This may effect a cure, but in a case where it grows again, or 

 where the growth is very bad before operating, or the bones duh 

 eascd, have the animal destroyed immediately.
