proving very injurious to the eye-sight. It proceeds from exposure

result of inflammation, comes over the cornea, extending no deeper 

 than the surface, and may vary from a slight cloudiness to entire 

 opacity. 



Treatment. — This must, in a great measure, depend upon the 

 cause; therefore it is of the greatest importance to make a careful 

 examination, especially if but one eye is affected. 



If there is any foreign matter in the 

 eye, remove it promptly, which can 

 be done either by means of a feather 

 or a pair of forceps. The eye should 

 be fomented with tepid or warm wa- 

 ter, and the horse kept in a darkened 

 stable or loose-box; next, the eye may 

 be kept constantly moist by means of 

 a sponge or cloth, wet with tepid or 

 cold water, and applied over the eye ; 

 or better, Goulard's extract, used in 

 the proportion of 1 drachm to a pint 

 of watei'. If accompanied by great pain, the following lotion 

 should be applied around the eye several times a day : — 



1 ounce watery infusion of opium, 

 4 ounces Goulard's extract, 

 12 ounces water.
