 8vo. old calf, neivly rebac/ced (fine copy) ; VERY RARE, 1. 15* 1786 



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

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

 glycerine, and sulphuretted hydrogen gas, obtained the salts of manganese, and showed how manganese colours glass. 

 His name is familiar in ' Scheele's green', the pigment produced byarsenite of copper, which he first described, and for a 

 strong solution of prussic acid, tirst obtained from ferrocyanida of potassium, which is well-known to the medical profession.

 old hf. C//(VERY RARE), 1. 10* 1780 



'In his treatise on 'Air and Fire' he. 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 ' fixed 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 plants. 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.'
