THE HORSE, ITS DISEASES. 427 



Colts are often subject to inflammation of the eyes in a slight degree, 

 during teething. Examine the teeth, lance the gums, and the eyes will 

 recover. It is a case of sympathy. 



n. Sore Eye-lids. 



In the outset of more serious disease, soreness of the lids of the eyes 

 Ts common. It is also produced by irritation of various kinds. In in- 

 flammation of the eyes, soreness of the lids is always present. If from 

 other disease, it is sympathetic, and will pass away with the disease itself. 



There is one form, however, that is characterized by a redness, spell- 

 ing and itching, the edges becoming raw and exuding matter. This must 

 have specific treatment. 



What to do. — The horse should have a laxative dose if the bowels arc

No. 163. 1 Drachm flowers of sulphur, 



2 Drachms powdered mandrake, 



3 Drachms powdered aloes. 



Form into a ball with honey, and give as a dose. 



To reduce the inflammation, make a curd, by beating three eggs thor- 

 oughly and then stirring them, with a quart of filtered rainwater until 

 mixed ; let it come to a boil, stirring occasionally. Add half an ounce of 

 sulphate of zinc, and continue the boiling for a few minutes. Bind the 

 curd over the eyes, by placing a portion between layers of thin muslin. 

 The clear water strained through several thicknesses of fine linen is excel- 

 lent for sore or inflamed eyes of any kind. "Wet the lids three or four 

 times a day. 



In aggravated cases that will not yield to treatment, and that remain 

 raw and exude matter, the edges should be carefully touched with mer- 

 curial ointment, the utmost care being taken that it does not come in con- 

 tact with the eye. 



During the whole treatment the horse must be tied up by two lines to 

 the rear posts of the stall, so he cannot rub the eyes, and must be fed 

 from a nose-bag. 



m. Moon Eyes. 



This is ophthalmy, recurring at periodic times, or at intervals of three 

 weeks, a month or more, and not, as is often supposed, at the full moon. 



Causes. — Hereditary predisposition ; from malarial causes ; herding in 

 low, damp situations ; rheumatic affections ; irritation consequent on
