2 PHYSIOGRAPHY. Achmite.—Aischynite. 3. It is found engaged in Quartz near Kongsberg in Norway. 4. This mineral has been referred to Pyroxene by several mineralo gists, from which substance, however, it appears sufficiently distinct. Achyrite. (See Dioptase.) Acicular Bismuth Glance.

The most transparent and pure varieties of Albite and Feld spar, q. v. Aequinolite. (See Pitchstone.) Aerosite. (See Red Silver.) Agalmatolite. (See Figure-stone.) Agaric Mineral. (See Calcareous Spar.) Agate. (See Quartz.) AISCHYNITE. Prismatoidal Eruthrone-Ore. Primary form. Right rhombic prism. Secondary form. The primary, terminated by 4-sided pyramids. Lustre sub-metallic. Color black. Streak dark grey to black. Hardness =5-0. ..7’0. Sp.gr. =5T4. ..5-55. 1. In the matrass, it yields a little moisture, without altering its appear ance. In an open tube it affords distinct traces of Fluoric acid. At an incipient red heat, upon charcoal, or in the platina forceps, it puffs up and enlarges in all its dimensions, especially in the direction of its cleav age, curls over to one side and remains without fusing of a dull yellow color. With borax, it is dissolved in large quantities; the glass present ing a dark yellow color both in the oxidation and reduction fire of the blow-pipe. When the mineral is added in excess, the glass after cool-
