In the foregoing table the acids and alkalies 

 point refpectively to the falts which they compofe, 

 Thus the nitrous compound falts are placed in 

 the fecond column, under the nitrous acid ; and 

 on the left fide the particular alkali, with which 

 each compound fait is combined, and fo on of 

 all the others. 



Thefe neutral or compound falts may be de- 

 compofed by the addition of an acid or alkaline 

 fait % and their attractions are in proportion to the 

 order fet down in the table : thus if we want to 

 feparate a volatile alkali from an acid, either of 

 the fixed alkalies will anfwer. There is no line 

 drawn between the fofTil and vegetable alkalies, 

 becaufe their powers of attraction are nearly the 

 fame. The acid falts are likewife placed in the 

 fame order of attraction ; the firft column, or 

 vitriolic acid, feparates the fecond or nitrous 

 acid and this the third or muriatic acid, and fo 

 on of all the reft. 



3. Metallic compound salts, metal difr 

 folved in the vitriolic acid. 



a. Blue vitriol, vitriolic acid and copper. 



b. Green vitriol, vitriolic acid and iron. 



c. "White vitriol, vitriolic acid and zinc. 



d. Arfenic is found in a faline ftate, being folu- 

 blc in boiling water, yields a regulus by fub- 

 limation with the principle of inflammability. 

 Vide metals. 



4. Earthy salts, earth united with a mineral 

 acid. 



a. Rock alum, vitriolic acid and argillaceous 

 earth. 



b. Fixt fal ammoniac, muriatic acid and calca- 

 reous earth. 



c. Bitter
