DISEASES OF HORSES. 709 



dark, or extremely foul stables; very hot weather or very 

 bright sunlight may cause it. But it generally comes from 

 some injury. 



SYMPTOMS. The eye is partly or entirely closed. Tears run 

 down the face. There is generally supposed to be a film over 

 the eye, but this is a mistake, it is only an exudation between 

 the layers of the cornea. The eye also seems to be sunken in 

 its socket. 



TREATMENT. If caused by dirt, hay-seed, etc., remove it with 

 a feather, or camel's-hair brush ; and apply warm water to the 

 eye for a long time each day, for a day or two ; keep the animal in 

 a dark place, and if there is great pain, use one of the following : 



Take Laudanum, ....... 10 drops. 



Sulphate of Zinc, ..... 2 grains. 



Water, ........ 1 ounce. 



Mix, and apply with a camel's-hair brush or a small syringe ; or, 



Take Atropine Sulphate, ...... 2 grains. 



Distilled Water, ...... 1 ounce. 



Or Sulphate of Copper, ...... 5 grains. 



Water, ........ 1 ouuce. 



Apply as above. If the white or cloudy appearance re- 

 mains, use 



Nitrate of Silver, 5 grains. 



Distilled Water, ...... 1 ounce. 



Or Iodide of Potash, ...... 5 grains. 



Water, ........ 1 ounce. 



Use any of the above washes, two or three times a day, 

 applying with a camel's-hair brush or fine feather. 



Splints are bony enlargements, usually on the inside of the 

 fore-leg below the knee, but they sometimes occur on the out- 

 side of the leg. They are rarely seen on the hind-leg. They are 

 usually seen on young horses, but they may be seen on old ones. 



CAUSES. Irregular or hard work ; shoeing with heavy shoes, 

 which bring the feet to the ground with great force. Horses 

 that are driven on hard roads are more subject to splints than 

 race horses, although the latter are more violently driven, but 

 on soft roads.
