 inflammation. Orfila remarked that two drachms, when mixed

Copper, like tin, has been long known ; it is extensively used in 

 the arts, and many of its compounds for medicinal purposes. It 

 occurs native, in combination with several of the metals, and with 

 sulphur, oxygen, and various acids ; hence its ores are numerous. 

 It is found in most parts of the globe, but the richest copper-mines 

 are situated in Cornwall. Nearly all the copper of commerce is 

 obtained from copper pyrites and grey copper ore.
