FORMALIN—FORMALINE.
Derivation.—Formalin is a forty per cent, aqueous solution of
formaldehyde, (CHgO). It is a colorless, neutral, volatile liquid
with a pungent odor and slightly irritating taste. It mixes in all
proportions with water, and a solution of any required strength can
be readily made. Taken internally in small doses it does not pro-
duce any toxic effect.
Formaldehyde, formyl or formol, is a gaseous body, obtained by
the oxidation of methylic alcohol at a moderately high tempera-
ture; and, according to Lilly, has the chemical property of unit-
ing with sulphuretted or nitrogenous products of decay, fermen-
tation or decomposition, forming true chemical compounds which
are odorless and sterile ; and these compounds are in most cases
actually antiseptic themselves ; hence it is from this property of
