M. PacchiaNi, of Pifa, has difco- 

 vered that the radical of muriatic-acid is 

 hydrogen. By taking from water, by

 confequently muriatic-acid is hydrogen at 

 its minimuin of oxidation ; thecxymuri- 

 atic-acid, hydrogen in the middle ftate ; 

 and water, hydrogen at its raaxiinum of 

 oxidation. A full account of this fubjcfl
