Pertaining to, or derived from, a ferricyanide. Ferricyanic acid (Chem.), a brown crystalline substance, H6(CN)12Fe2, obtained from potassium ferricyanide, and regarded as the type of the ferricyanides; -- called also hydro-ferricyanic acid, hydrogen ferricyanide, etc.

nd some other base. Potassium ferricyanide (Chem.), red prussiate of potash; a dark, red, crystalline salt, K6(CN)12Fe2, consisting of the double cyanide of potassium and ferric iron. From it is derived the ferrous ferricyanate, Turnbull's blue.

ining to, derived from, or designating, a ferrocyanide. ferrocyanic acid (Chem.), a white crystalline substance, H4(CN)6Fe, of strong acid properties, obtained from potassium ferrocyanide, and regarded as the type of the ferrocyanides; -- called also hydro- ferrocyanic acid, hydrogen ferrocyanide. etc.…

other base. Potassium ferrocyanide (Chem.), yellow prussiate of potash; a tough, yellow, crystalline salt, K4(CN)6Fe, the starting point in the manufacture of almost all cyanogen compounds, and the basis of the ferric ferrocyanate, prussian blue. It is obtained by strongly heating together potash, scrap iron, and anim…

A yellow crystalline substance extracted from fustet, and regarded as its essential coloring principle; -- called also fisetic acid.

A yellow, crystalline, organic dyestuff, C16H14N2, of artifical production. It is a strong base, and is a complex derivative of aniline and quinoline.

A yellow, crystalline, organic base, C13H12N2O, obtained artificially.

A yellow, crystalline substance, obtained from anthraquinone, and regarded as a hydroxyl derivative of it.

A white crystalline hydrocarbon C

A colorless, crystalline hydrocarbon, C13H10 having a beautiful violet fluorescence; whence its name. It occurs in the higher boiling products of coal tar, and is obtained artificially.

A yellowish red, crystalline substance, C20H12O5, produced by heating together phthalic anhydride and resorcin; -- so called, from the very brilliant yellowish green fluorescence of its alkaline solutions. It has acid properties, and its salts of the alkalies are known to the trade under the name of uranin.…

Laminated, but restricted to the variety of laminated structure found in crystalline schist, as mica schist, etc.; schistose.

The property, possessed by some crystalline rocks, of dividing into plates or slabs, which is due to the cleavage structure of one of the constituents, as mica or hornblende. It may sometimes include slaty structure or cleavage, though the latter is usually independent of any mineral constituent, and transverse to the…

lin, or a species (Rhamnus Frangula) of the buckthorn. Frangulinic acid (Chem.), a yellow crystalline substance, resembling alizarin, and obtained by the decomposition of frangulin.

A yellow crystalline dyestuff, regarded as a glucoside, extracted from a species (Rhamnus Frangula) of the buckthorn; -- called also rhamnoxanthin.

A colorless crystalline substance, regarded as a glucoside, and found in the bark of the ash (Fraxinus) and along with esculin in the bark of the horse-chestnut. It shows a delicate fluorescence in alkaline solutions; -- called also paviin.

and cyanuric acids, and designating an acid so called. Fulminuric acid (Chem.), a white, crystalline, explosive subatance, H3C3N3O3, forming well known salts, and obtained from the fulnunates. It is isomeric with cyanuric acid, and hence is also called isocyanuric acid.

An alkaloid extracted from fumitory, as a white crystalline substance.

A white, crystalline base, obtained indirectly from furfurol.

A yellow, crystalline substance, (C4H3O)2.C2O2, obtained by the oxidation of furoin. [Written also furil.]
