294 DISEASES OF HORSES AND CATTLE. 



as the vitreous humor will never be replaced. On 

 the other hand, if the cornea is the part punctured, 

 as soon as it heals it will fill up again. There will 

 be considerable inflammation in the eyeball and 

 surrounding structures and the animal will suffer 

 much pain. 



Treatment : Keep the animal in a dark place and 

 bathe the eye several times a day with cold water; 

 after each bathing put several thicknesses of mus- 

 lin over the wounded eye; wet it often with a little 

 of the following lotion: Acetate of lead, half an 

 ounce; tincture of opium, one ounce; water, one 

 quart. This plan of treatment will reduce the in- 

 flammation and assist in causing contraction of 

 the opening. It is best not to put any medicine 

 into the eye, as it is apt to remove any coagulated 

 material that is formed in the puncture or around 

 it, allowing more to escape. I usually keep up 

 this treatment for a week, and by this time the in- 

 flammation will be reduced, and in favorable cases 

 the opening will be closed, and if there is a scum 

 over the eye or part of it, mix four grains of sul- 

 phate of zinc in one ounce of water and apply a 

 little of this to it twice a day with a feather. If 

 there is a little bunch at the puncture this should 

 be touched gently once a day with a pencil of ni- 

 trate of silver until it is reduced as low as the edges 

 of the opening, which will then likely close.

 be ulcers on the cornea, usually at the juncture of 

 the cornea and sclerotic. This is best treated by
