The author's most iinportanr work, containing accounts ot his discovery of hydrofluoric, tartaric, benzoic, arsenious, 

 niolybdic, lactic, citric, malic, oxalic, gallic, and other acids. He also separated independently chlorine. I aiyta, oxygen, 

 frlycerine, and sulphuretted hydrogen pas, obtained the salts of manganese, and showed how manganese cclours glass. 

 His name is familiar in ' Scheele's green ', the pigment produced by arsenite of copper, which he hrst desciibed, and for a 

 strong solution of prussic acid, first obtained from ferrocyanidi^ of potassium, which is well-known to the medical profession.

' In his treatise on ' Air and Fire ' lie showed that the air consists essentially of two gases, one of which supports 

 combustion whilst the other does not. The former he identified with the ' Jixed air' he obtained from saltpetre, nitric 

 acid, black oxide of manganese, and other substances. He endeavoured to associate several phenomena with the action 

 of this gas, particularly connecting it with the respiratory function and the growth of i)lants. Incidentally he prepared 

 and described sulphuretted hydrogen, and by his experiments on the action of light upon chloride of silver and other 

 substances, he took the first step in the direction of discovering the art of photography.'
