definitions of the several known acids, and abridged accounts of the
processes by which they are obtainable, with a mere nomenclature or
enumeration of the neutral salts which result from the combination of
these acids with the various salifiable bases. But I afterwards found
that the addition of similar Tables of all the simple substances which
enter into the composition of the acids and oxyds, together with the
various possible combinations of these elements, would add greatly to
the utility of this work, without being any great increase to its size.
These additions, which are all contained in the twelve first sections of
this Part, and the Tables annexed to these, form a kind of
recapitulation of the first fifteen Chapters of the First Part: The rest
of the Tables and Sections contain all the saline combinations.
It must be very apparent that, in this Part of the Work, I have borrowed
greatly from what has been already published by Mr de Morveau in the
First Volume of the _Encyclopedie par ordre des Matieres_. I could
hardly have discovered a better source of information, especially when
the difficulty of consulting books in foreign languages is considered. I
make this general acknowledgment on purpose to save the trouble of
references to Mr de Morveau's work in the course of the following part
of mine.
