t the reader will take care not to confound what
I have related as truths, fixed on the firm basis of observation and
experiment, with mere hypothetical conjectures.

The fixed alkalies, potash, and soda, are omitted in the foregoing
Table, because they are evidently compound substances, though we are
ignorant as yet what are the elements they are composed of.

TABLE _of compound oxydable and acidifiable bases._

_Names of the radicals._

Oxydable or acidifiable { Nitro-muriatic radical or
base, from the mineral { base of the acid formerly
kingdom. { called aqua regia.

{ Tartarous radical or base.
{ Malic. }
{ Citric. }
{ Pyro-lignous. }
Oxydable or acidifiable { Pyro-mucous. }
hydro-carbonous or { Pyro-tartarous. }
carbono-hydrous radicals { Oxalic. }
from the vegetable { Acetous. }
kingdom. { Succinic. } Radicals
{ Benzoic. }
{ Camphoric. }
{ Gallic. }
}
Oxydable or acidifiable { Lactic. }
radicals from the animal { Saccholactic. }
kingdom, which { Formic. }
mostly contain azote, { Bombic. }
and frequently phosphorus. { Sebacic. }
{ Lithic. }
{ Prussic. }

_Note._--The radicals from the vegetable kingdom are converted by a
first degree of oxygenation into vegetable oxyds, such as sugar, starch,
and gum or mucus: Those of the animal kingdom by the same means form
animal oxyds, as lymph, &c.--A.

SECT. II.--_Observations upon the Table of Compound Radicals._

The older chemists being unacquainted with the composition of acids, and
not suspecting them to be formed by a peculiar radical or base for each,
united to an acidifying principle or element common to all, could not
consequently give any name to substances of which they had not the most
distant idea. We had therefore to invent a new nomenclature for this
subject, though we were at the same time sensible that this nomenclature
must
