lids, as well as its extension over the white of the eye, is 

 also inflamed. At a later stage the tears give way to a 

 purulent discharge, and ulceration and even blindness 

 may ensue. 



Treatment. — Remove foreign bodies ; place the animal 

 in a dark stable with proper admission of air ; bathe the 

 eye with cold water for one or two hours, and cover with 

 light cloth fixed to the headstall, which is to be con- 

 tinuously saturated with an astringent lotion, No. 1 or 2 ; 

 remove constipation by mild aperients, Nos. 1 or 2, 

 and follow daily with febrifuges, Nos. 1, 2, or drench 

 No. 3, with a few drops of aconite. Belladonna to the 

 eyebrows, &c, for removing adhesions, and remaining 

 opacity may be treated with a weak solution of nitrate of 

 silver, after all acute symptoms are abated. Subcutaneous 

 Injections, No. 2. 



Specific Ophthalmia. — This is inflammation of the 

 deeper- seated structures, liable to recur, and eventually 

 destroy the sight. One eye only, as a rule, is affected, 

 the attack coming on during the night, leaving the eye 

 dull and turbid as seen through the pupil. The blood 

 vessels are injected, the eye is painful and unable to bear 

 the light, the system is greatly disturbed, and the animal 

 suffers in proportion from general interference with all 

 the functions. In a few days the disease suddenly dis- 

 appears ; but it shortly recurs, and by each attack the 

 organ is injured, when finally pus forms in the interior, or 

 the sufferer becomes stone-blind from interstitial deposits 

 of inflammatory exudation. 



Treatment. — As simple ophthalmia. When these affec- 

 tions accompany an outbreak of influenza, the disease is 

 intractable, and treatment unsatisfactory. 



Cataract is caused by inflammatory deposit on the 

 surface of the crystalline lens, sometimes amounting only 

 to a small speck, or extending in others to the whole 

 surface, when blindness is the result. 



Staphyloma is the result of repeated attacks of 

 ophthalmia, associated with debilitating tendency, during 

 which the front portion of the eyeball suffers from ulcera- 

 tion of one of its layers. Thus weakness is induced, and
