JL HE illustrious discoverer of the oximuriatic acid con- Discovery of 



, oxitr 

 'acid. 



sidered it as muriatic acid freed from hidrogen + ; and the *^-'^|f"^"*^'*^ 



common muriatic acid as a compound of hidrogen and oxi- 

 muriatic acid; and on this theory he denominated oxi- 

 muriatic acid dephlogisticated muriatic acid. 



Mr. Berth oUet +, a few years after the discovery of 

 Scheele, made a number of important and curious experi* 

 ments on this body ; from which he concluded, that it 

 was composed of muriatic acid gas and oxigen; and this 

 idea for nearly twenty years has been almost universally 

 adopted.
