s common to
them all; 2d, The acidifiable principle which constitutes their peculiar
acid; 3d, The saline, earthy, or metallic basis, which determines the
particular species of salt. Here we derived the name of each class of
salts from the name of the acidifiable principle common to all the
individuals of that class; and distinguished each species by the name of
the saline, earthy, or metallic basis, which is peculiar to it.
A salt, though compounded of the same three principles, may,
nevertheless, by the mere difference of their proportion, be in three
different states. The nomenclature we have adopted would have been
defective, had it not expressed these different states; and this we
attained chiefly by changes of termination uniformly applied to the same
state of the different salts.
In short, we have advanced so far, that from the name alone may be
instantly found what the combustible substance is which enters into any
combination; whether that combustible substance be combined with the
acidifying principle, and in what proportion; what is the state of the
acid; with what basis it is united; whether the saturation be exact, or
whether the acid or the basis be in excess.
It may be easily supposed that it was not possible to attain all these
different objects without departing, in some instances, from established
custom, and adopting terms which at first sight will appear uncouth and
barbarous. But we considered that the ear is soon habituated to new
words, especially when they are connected with a general and rational
system. The names, besides, which were formerly employed, such as
_powder of algaroth_, _salt of alembroth_, _pompholix_, _phagadenic
water_, _turbith mineral_, _colcathar_, and many others, were neither
less barbarous nor less uncommon. It required a great deal of practice,
and no small degree of memory, to recollect the substances to which they
were applied, much more to recollect the genus of combination to which
they belonged. The names of _oil of tartar per deliquium_, _oil of
vitriol_, _butter of arsenic and of antimony_, _flowers of zinc_, &c.
were still more improper, because they suggested false ideas: For, in
the whole mineral kingdom, and particularly in the metallic class, there
exists no such thing as butters, oils, or flowers; and, in short, the
substances to which they give these fallacious names, are nothing less
than rank poisons.
