Sulphur e, Sulphur et of the Englijh. 



By this the French underftand the compound of fulphur ftngly. 

 with any bafes except hydrogen ; thefe compounds I call bepars 

 if unmetallic, bat if metallic I apply their antient names. 



" Hydrogene Sulphuric Sulphurated Hydrogen. 



This complex denomination expreffes the union of fulphut 

 with hydrogen. I call it by its ancient name, hepatic air. 



Souffre Hydrogene 



This term expreffes the union of fulphur with hepatic air, 

 the fulphur abounds and it does not form a permanent air, but 

 affumes an oily form. Englifh neologifts would, I prefumc, have 

 called it hydrogenated fulphur ; it is plain that this name does not 

 exprefs all the ingredients, for it is to hepatic air and not merely 

 to hydrogen that the fulphur is united ; I call it therefore hepati- 

 cflted fulphur. 



Hydro Sulphur e. 



Hepatic air is capable of uniting to various bafes, and even 

 precipitates fulphur from them if previoufly united to them; 

 on thefe compounds Berthollet beftows the above denomination. 

 The Englifh, I fuppofe, would call them hydrofulphurets ; I call 

 them 'epatu'es.
