Page iv - Every true mineral is a definite chemical compound or element, homogeneous throughout its parts, and capable of expression in a formula. Its molecule is a distinctive whole — the unit of its mass — and incapable of division as long as the mineral retains its characteristic properties.
Page 69 - ... crystals; generally in irregular flakes and scales showing cleavage. Associations: orthoclase, quartz, biotite, hornblende, albite. Rocks: granites, felsites, pegmatites, schists, gneisses, arkose. Alteration: very resistant, but loses its elasticity, luster and transparency. Tests: Heated strongly in closed tube gives water. BB whitens and fuses on thin edges to yellowish glass. Insoluble in acids. SERICITE, is a silvery-white variety of muscovite occurring in minute silky scales and fibrous...

If turmeric paper is moistened with this water, and then with dilute muriatic acid, it assumes a red color (boric acid). In the forceps fuses in the flame of a candle (F=2), and BB in OF yields a black crystalline mass, coloring the flame intensely yellowish-green. With the fluxes reacts for manganese. Soluble in chlorhydric acid. Found on Mine Hill, Franklin Furnace...

Page 97 - BB in forceps becomes brown and glassy but does not fuse. Colors flame green.
Page 109 - BB emits fumes of As and Sb, and fuses to a metallic globule, which ignites and burns away, leaving Sb 2 0 a on the charcoal.
