Uses External. — Copper sulphate is employed in the solidj crystal- 

 line form in granular conjunctivitis, by rubbing the stick over the affected 

 surfaces of the lids. 



A solution (gr.-ii. to §i.) is dropped into the eye for simple conjunc- 

 tivitis. Copper sulphate is similar in action to zinc sulphate, but more 

 powerful. On ulcerated and granular surfaces it is used as a stimulant 

 and astringent in the following mixture, which is of value in thrush and 

 canker of the feet in horses, and as an application for not too extensive 

 chronic sores and unhealthy indolent granulating surfaces :

S. Apply externally. 



It may also be applied locally with an equal part of dried aliim in 

 the form of powder for the treatment of thrush. The disappearance of 

 the moisture and foul odor will soon herald recovery. In foot rot of 

 sheep one part each of copper sulphate and lard, with two of tar, may 

 be prepared by melting and then mixing the ingredients. 



Two ounces each of zinc and copper sulphate in one pint of vinegar 

 are curative when injected into sinuses. 



Uses Internal. — Copper sulphate is prescribed for its local effect 

 with opium in diarrhea, and injected into the bowel in 2 per cent, solution 

 in ulcerated conditions of the rectum. The sulphate of copper in small 

 doses is believed to be a tonic remedy in anemia and nervous conditions, 

 although without sufficient experimental proof. It is thought to resemble 

 arsenic and to increase the number of corpuscles, firmness of flesh and 

 amount of fat. Copper sulphate is often used as a vermicide in the treat- 

 ment of lumbricoid worms and ozena, combined with iron.

 of 1 to 2 years, giiss-giiiss. A dose of about an ounce and a half (50 mils) 

 of a one per cent, solution of copper sulphate has proved the best remedy 

 against stomach worms of sheep (Hemonchus contortus). It is recom- 

 mended in purpura, and is given to dogs in the form of arsenite of copper 

 for chorea and epilepsy. Copper sulphate, added to reservoirs of drinking 

 water in the proportion of 1 part to 5 to 50 millions of water, destroys 

 algae but is innocuous to animals. Copper sulphate forms an inert com- 

 pound with phosphorus. Hydrogen dioxide or potassium permanganate
