SECT. V.--_Observations upon the Combinations of Oxygen with the
Compound Radicals._

I published a new theory of the nature and formation of acids in the
Memoirs of the Academy for 1776, p. 671. and 1778, p. 535. in which I
concluded, that the number of acids must be greatly larger than was till
then supposed. Since that time, a new field of inquiry has been opened
to chemists; and, instead of five or six acids which were then known,
near thirty new acids have been discovered, by which means the number of
known neutral salts have been increased in the same proportion. The
nature of the acidifiable base
