addition of either the nitrous or acetous acids; 

 the filver uniting with the muriate acid of the 

 fait, forms luna cornea, a fubftance fcarcely at 

 all foluble in water ; the nitrous acid unites 

 with the mineral alkali of the fait, forming cubic 

 nitre, which remains diffolved in the water. 



c. Upon adding the mercurial folution, white 

 clouds will immediately appear, and a precipitate 

 of the fame colour will fubfide to the bottom. 



In this inftance the muriatic acid of the fait 

 unites with the mercury, forming calomel and 

 corrofive fublimate; the calomel being almoft 

 infoiuble in water, is precipitated. The corro- 

 five fublimate remains diffolved in the water, 

 with the cubic nitre, formed by the nitrous acid 

 and the mineral alkali.
