and cool feed. Give, also, half-ounce doses of sulphite 

 of soda daily for a few days. The nitrate of silver lo- 

 tion, or the blue stone, will do; it is cheap and easily 

 procured, and therefore better adapted for the farmer or 

 stable man. Apply as elsewhere recommended. Never 

 use sugar of lead lotions as an eye-wash to the eye, 

 which books so often recommend. They are positively 

 injurious to the eye by their producing dulness, or opa- 

 city of the cornea— or the clear, transparent part of the 

 eye the very brightness of which indicates health, beau- 

 ty, and intelligence in a horse ; so, once for all, I say, 

 use no Goulard's solution of lead. Copper is infinitely 

 better, and never leaves dimness of the eye or vision. If 

 copper be not at hand, chloride of zinc, one grain, to an 

 ounce of rain or distilled water, is an excellent applica- 

 tion to the eye of a horse suffering from purulent oph- 

 thalmia. (See Medicines and Prescriptions.) 



(12.) Moon Blindness, terminating in Cataract.— 

 This disease is a serious one, and frequent, consisting of 

 inflammation of the internal parts of the eyeball, the cho- 

 roid coat and the iris more particularly. 



Symptoms.— Iw the morning, perhaps, the eyelids will 

 be found closed; a large flow of tears; the back portion 

 of the eye dim and clouded. No specks are to be seen, 

 as in some other diseases of the eye. A yellow border 

 will be observed at the bottom of the chamber. This is 

 pus. The attack, or inflammation, will last from two to 

 three weeks ; at the end of which time the eye will brighten 

 up, and the ordinary observer may think that the eye is 

 completely cured. The pus is entirely absorbed, scarcely 

 leaving any traces behind, except a degree of dimness.
