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

 simple conjunctivitis. 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, 

 as in the following mixture, a combination of cupric sul- 

 phate and zinc sulphate, of each 2^ drachms (lOgm.,), with 

 solution of lead subacetate, 5 drachms (2Q gm.), which is of 

 value in thrush and as an application for chronic sores and 

 unhealthy indolent granulating surfaces. It may also be 

 applied locally with an equal part of dried alum in the form 

 of powder for the treatment of thrush. The disappearance 

 of the moisture and foul odor will soon herald recovery. 



Uses Internal. — Copper sulphate is prescribed for its 

 local effect with opium in diarrhoea, and injected into the

 fi,rmnes8 of flesh and amount of fat. Copper sulphate is often 

 used as a vermicide in the treatment of lumbricoid worms 

 and ozoema, combined with • iron. Copper sulphate in 1 

 drachm doses (4.0 gm.), with powdered charcoal and fenu- 

 greek, of each 1-1^ drachms (4.0-6 gm.), given to the horse 

 night and morning for eight to ten days and followed by a 

 brisk cathartic of aloes and linseed oil,, will cause the expul- 

 sion of ascarides. It is recommended in purpura, and is 

 given^ to dogs in the form of arsenite of copper for chorea 

 and epilepsy. Copper sulphate, added to reservoirs of drink- 

 ing water in the proportion of 1 part to 5 to 50 millions of 

 water, destroys algae but is innocuous to animals.
