DISEASES OF HORSES AND CATTLE. 47 



the physic does not operate in twenty-four hours, 

 repeat the salts and quinine. Injections of soap 

 and warm water are useful. Aloes in one ounce 

 doses mixed with one pound of Epsom salts have

 Treatment: Remove the cause if possible. If 

 from poison, give an antidote ; for instance, if the 

 poison is an alkali, give an acid, and if an acid give 

 an alkali; to reduce the inflammation, give linseed
