640 APPENDIX. in Sweden, Waldenburg in Silesia, Halle in porphyry by the decomposition of which it is produced. PITCHY COPPER OEE is a mechanical mixture of lim- nite with a hydrous silicate of oxide of copper. According to y. Kobell, a variety from Turinsk consists of:—red oxide of iron 59*00, black oxide of copper 13*00, silica 9*66, water 18*00. TTM13EE appears to be a mechanical mixture of limnite and hydrate of oxide of manganese and clay. Ferruginous red oxide of copper is a mixture of limnite with about 22 per cent, of red oxide of copper. URAjN’OCHRE.—Amorphous. Practure earthy ...imperfect conchoidal. Opaque. Dull... glimmering. Lemon-yellow... sulphur-yellow, brown. Soft, friable. In the matrass yields water and becomes red. Before the blowpipe in the inner flame becomes green without melting. With salt of phos phorus in the outer flame forms a yellow glass, in the inner flame a green glass. Easily soluble in acids. Probably oxide of uranium and water in unknown proportions. Occurs massive, disseminated, investing other minerals. Is found with pechuran, of the decomposition of which it is a product, with torberite, antunite, at Joachimsthal and Johann-Georgenstadt, and in metallic veins in granite at St. Symphorien in France. YAEYICITE.—Supposed to be decomposed manganite. In columnar and fibrous masses. Lustre metallic, imperfect. Iron-black... steel-grey. Streak black, h = 2*5... 3. a = 4*5... 4*6. Analysis, from Warwickshire, by Phillips:—manganese 63*3, oxygen 31*7, water 6 ; from Ihlefeld by Duflos:—protoxide of manganese 81*41, oxygen 13*47, water 5*13. ADINOLE is a mechanical mixture of albite and quartz found at Sahla and in the Harz, h = 6*6. a = 2*617...2*640. Analyses of adinole from Lerbach in the Harz by Schneder- mann :—silica 71*60, alumina 14*76, soda io*oo, potash 0*32, lime 1*06, red oxide of iron with traces of protoxide of manga nese 1*41. AiGYRINE. — Probably isomorphous with augite. a loo, b 010, m no. ma = 46° 34', mb = 43° 26', mm' = 86° 62'. Cleavage, a, b, m. Greenish-black...blackish-green. Streak greenish-grey, n = 5*5...6*76. a = 3*432...3*604. Is found with leucophane in the island of Skaadon near Brevig.
