Bladder, Inflammation of the (Cystitis). 



This disease is not very often met with in the horse. 

 It may be produced by the administration of cantharides 

 or turpentine or crotoii oil, or by the absorption of can- 

 tharidine from a blister ; or again, it may be set up by the 

 presence of calculi or morbid growths in the bladder. The 

 malady causes great restlessness, intense discomfort and 

 pain, and although the horse tries to pass water frequently, 

 it only succeeds in doing so with great difficulty. 



If there be any blistering agent, wash it off at once. 

 Begin treatment with a mild purgative, and follow on with 

 opium, liyoscyamus, or belladonna. Buchu and copaiba, 

 with saline purgatives, are sometimes useful, and in certain 

 cases very small doses of mineral acids and iron may be 

 tried. 



Draught. 



Tincture of aconite (B.P.), twenty minims. 

 Tincture of opium, one fluid ounce and a half.
