phlogopite

[Gr. phlogōpos =fire-like; suff. -ite ( Min.).] Min.: A member of the Mica (q. v.) group of minerals, formerly regarded as orthorhombic, but now referred to the monoclinic system of crystallization. Tschermak refers it to his division of the micas in which the optic axial plane is parallel to the plane of symmetry. It is a magnesian mica, and is almost peculiar to serpentine and dolomitic limestone rocks. Chem. C6H6O3. Phloroglucol. Formed from phloretin by the action of potashlye. The phlore- tate of potash produced is removed by alcohol, and the residue, after neutralizing with sulphuric -ic .) (See the compound.) acid and evaporation, deposits crystals of phloro- tion. The hydrated crystals belong to the trimetric glucin, which may be purified by re-crystal liz a- ACID.] system, are sweeter than cane-sugar, neutral, permanent at common temperatures, and melt at 220°. They di olve in water, alcohol, and ether, strike a violet-red color with ferric chloride, and reduce copper salts like dextrose. Phloroglucin forms several substitution products, of which tribromophloroglucin is a type-C6H3Br303. nective, and glucol .] [PHLOROGLUCIN.] phlör-o-glu-col, s.

A colorle oily liquid, one of the constituents of beech-tar creosote, obtained by repeated frac- tional distillation of that portion, boiling between turns red. 217-220°. On exposure to the light it gradually phlör -ōne, 8. [Eng. phlor (izin); suff.-one.] Chem.: C8H8O2. A compound obtained by dis- tilling two parts coal-tar creosote with three parts oil of vitriol, and adding peroxide of manganese from time to time. It comes over in yellow drops, which quickly solidify, and it forms, when recrys- tallized, fine yellow needles, soluble in alcohol, and slightly soluble in water. It melts at 60°, smells like quinone, and, like that body, is turned brown by potash. phlör-1, s . [Eng. phlor (izin); -yl.] (See com- pound.) phloryl-alcohol, s . [PHLOROL.] phlox, s . [Lat., from Gr. phlox =a flame, which the flower resembles.] Bot.: A genus of Pole mon i a cere. They are gen- erally perennials with salver-shaped white, blue, red, or variegated corollas, and one-seed capsular fruit. Natives of this country. Bot.

Head round and short; fore feet short, with five very strong sub-equal claws, which are narrow on hind feet. The number of species is variously stated by different authorities. Gray multiplied genera, on grounds now scarcely deemed valid. Phoca vitulina is the Common Seal, P.groen- landica , the Green land, P. barbata , the Bearded, and P. hispid a , the Ringed Seal. P. caspica and but Van Beneden considers them both identical P. siberica (or baikalensis ) are often discriminated. phō-çæ-na, s. [Lat., from Gr. phōkain a . ] Zool .: Porpoise; a genus of Delphin ide with two species, from the North Sea. Head short, moder- ately rounded in front of the blowhole; dorsal fin (in typical species) near middle of back, triangular, its anterior edge frequently furnished with one or more rows of conical horny tubercles. A closely allied species, P. melas , from Japan (the genus Neo- meris of Gray), wants the dorsal fin. IMG:content-0995.png:[blocks in formation] Zool .
