be administered ; it is not a ball, but a drink, being 

 composed of an ounce each of sulphuric ether and of 

 laudanum, in a pint of cold water. It is given so soon 

 as it is thoroughly mixed. 



Copper {Cuprum) yields two articles used in veterinary 

 practice. 



Verdigris (^rugo). This subacetate of copper has 

 been given internally in daily doses of two or three 

 drachms, and sometimes with success ; but it does not 

 appear to merit the exclusion of other remedies. It has 

 however some power as a tonic, and, in this point of 

 view, may be properly administered. Externally, its 

 benefits are more apparent, as it proves one of the best 

 detergents and mild escharotics with which we are 

 acquainted. Mixed with honey, it forms segyptiacum, 

 and is used in ulcers of the mouth, and likewise as a 

 paste to other ulcerated parts. Mixed with tar, it forms 

 a good application for thrushes, grease, and cracks. 



Blue Vitriol (Cupri sulphas). — This has been at one 

 time lauded to the skies ; at another abused to the 

 shades; and, like most of the matters thus treated, its 

 merits lie between the two. It is, unfortunately, not a 

 cure for glanders ; but it certainly does, in some cases, 

 flatter much. It has been justly observed of it, that in 

 lingering chronic cases, the result of influenza, it proves 

 a most excellent tonic ; and here often it exerts its best 

 influence, and puts a stop to the discharge. It is also a 

 good detergent application in the proportion of half an 

 ounce to a pint of water ; or when injected into sinuous 

 sores in dilution, or sprinkled dry on unhealthy surfaces, 

 as canker, &c., its action is mild but effective. 



Coriander. — The seeds of the coriander are a w^arm 

 aromatic stimulant. 



Corrosive Sublimate {Hydrargyri oxymurias) . — See Mer- 

 cury. 



Cowhage. — This has been described as a valuable vermifuge 

 in doses of half a drachm to a drachm ; but it does not 

 appear to possess much medicinal activity on the horse. 



Cream of Tartar {Potasses supertartras) . — See Potash. 



Croton Tiglii. — In India this has long been used both as 

 a human and brute purgative, and lately it has entered
