    ments, the acidifying principle,and that which it acidifies, may exid in different proportions, con- ftituting all the poffible points of equilibrium or of faturation. This is the cafe in thefulphuric and the fulplnirous acids; and thefe two dates of the fame acid we have marked by varying the termination of the fpecific name. Metallic fubdances which have been expofed to the joint aflion of the air and of dre, lofe their metallic ludre, increafe in weight, and af- fume an earthy appearance. In this date, like the acids, they are compounded of a principle which is common to all, and of one which is pecu- liar to each. In the fame way, therefore, we have thought proper to clafs them under a ge- neric name, derived from the common prin- ciple ; for which purpofe, we have adopted the term oxyd ; and we diffinguidi them from each other by the particular name of the metal to which each belongs. Combudible fubdances, which in acids and metallic oxyds are fpecific and particular prin- ciples, are capable ofbecoming, in their turn, common principles of a great number of con- pounds. The fulphurous combinations have been
