Treatment. The application of cold water; or if the cold seem 

 to give pain, warm water should he used instead. Open the an- 

 gular veins. This is done as iollows : Take a sharp knife, and 

 simi)ly cut the skin and the veins which are seen underneath at 

 tlie lower corner of the eye, and bathe with warm water, whicli 

 will induce them to bleed freel3\ Give grass, or some other open- 

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

 daily for a few days. The nitrate of silver lotion, 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 ])roducing dulness, or opacity of the 

 cornea — or the clear, transparent part of the eye — the very bright- 

 ness of which indicates health, beauty and intelligence in a horse; 

 so, once for all, I sa}', 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 application to the eye of 

 a horse suffering from purulent ophthalmia. (See ]\Iedicines and 

 Prescriptions.) 



(12.) Moon Blindness, terminating in Cataract. — This dis- 

 ease is a serious one, and frequent, consisting of inflammation of 

 the internal parts of the eyeball, the choroid coat and the iris 

 more particularly. 



Symptoms. In 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 ab- 

 sorbed, scarcely leaving any traces behind, except a degree of 

 dinmess. In one, two or three months, and not l)y the regularity 

 of the moon's changes, as horsemen suppose, the disease reap- 

 pears, having the same symptoms and characteristics as in the 

 first attack, only a greater deposit of pus will be left at each sub-
