1. (Old Chem.) Of or pertaining to phlogiston, or to belief in its existence.
2. (Med.) Inflammatory; belonging to inflammations and fevers.
Phlogistical
(Phlo*gis"tic*al) a. (Old Chem.) Phlogistic.
Phlogisticate
(Phlo*gis"ti*cate) v. t. [imp. & p. p. Phlogisticated ; p. pr. & vb. n. Phlogisticating.]
(Old Chem.) To combine phlogiston with; — usually in the form and sense of the p. p. or the adj.; as,

Phlogiston
(Phlo*gis"ton) n. [NL., fr. Gr. burnt, set on fire, fr. to set on fire, to burn, fr. a flame, blaze.
See Phlox.] (Old Chem.) The hypothetical principle of fire, or inflammability, regarded by Stahl as a
chemical element.
This was supposed to be united with combustible (phlogisticated) bodies and to be separated from incombustible
(dephlogisticated) bodies, the phenomena of flame and burning being the escape of phlogiston. Soot
and sulphur were regarded as nearly pure phlogiston. The essential principle of this theory was, that
combustion was a decomposition rather than the union and combination which it has since been shown
to be.
Phlogogenous
(Phlo*gog"e*nous) a. [Gr. fire + -genous.] (Med.) Causing inflammation.
Phlogopite
(Phlog"o*pite) n. (Min.) A kind of mica having generally a peculiar bronze- red or copperlike

metameric with pyrogallol, and obtained by the decomposition of phloretin, and from certain gums, as
