Here it is evident that both Mefirs. Wenzel and Wiegleb 
agree in afferting that both alkalies take up more of the 
nitrous than of the vitriolic acid, contrary to the aflertion of 
Bergman. Mr. Morveau allows this as to Wenzel, but thinks 
that he was miftaken, yet he follows exactly the method of 
Bergman. Mr. Morveau thinks that nitre and cubic nitre, when 
barely melted, retain a confiderable portion of water, which Mr. 
Wenzel added to the portion of acid they contain; but. it is 
certain, that inftead of lofing water in fuch heats they lofe 
part of their acid, and confequently this fhould be diminifhed 
rather than increafed. Nor does it appear that Wenzel applied
