154 THE VETERINARY SCIENCE. 



Give the animal « leaspoonful of nux vomica in his feed three 

 times a day, this acts as a stimulant to the nerve ; wash the eye 

 with eye wash twice a day for a few days. In buying horses be 

 particular and watch the eyes closely for unsoundness, for some of 

 the best buyers have been nipped in this disease. 



CANCEROUS GROWTH IN THE EYE. 



It first commences with an inflammation in the eye, after this 

 there will be a growth noticed to be coming out of the ball of the 

 eye, which gradually keeps on growing until it hangs out over on the 

 cheek, it looks red and angry, and the least little injury will cause 

 it to bleed freely, and gives the animal an unsightly appearance. 

 In some cases the bones around the eye become diseased, and 

 then it smells very bad. This disease is more often met with 

 in the cow than in the horse. 



Causes. — The causes of this are like all other cancerous 

 growths — from cancer germs getting into the blood and settling 

 in the eye. 



Treatment. — You may effect a cure in the first stages of the 

 disease by removing the eye, growth and all. Cast the animal and 

 secure him, and have his head held solid, cut around the eye 

 between the eye and the eyelid, and lift the eye up by sticking a 

 hook into it, then out the structures off at the back part of the 

 eye and have a hot iron to sear it, to stop the bleeding, then allow 

 the animal to get up, and dress it the same as you would an ordinary 

 wound by bathing it with warm water and applying white lotion 

 three times a day. After applying the lotion, if the cut looks 

 angry, apply compound tincture of benzoin, or what is called 

 Frier's balsam, with a feather to keep it from growing again. 



FILARIA OCULL 



This is a small worm, about the size of a pin, found in the 

 humors of the eye, moving around. It is liable to be found in 

 any part of the body; they have been found around the testicles 

 and bowels. 



Causes. — From a microbe, and is mostly seen in horses that 

 pasture on low, wet land ; it is taken into the system through 

 water and feed, and from the bowels it gets into the blood and is 

 carried into the eye or various parts of the body through the blood. 



Symptoms. — This worm may grow from the size of one half 

 inch to two inches long, and it sets up considerable irritation in
