ASBOLANE. 279 Amorphous. Opaque. Lustre imperfect metallic, feeble. Clove-brown, passing into grey. Streak brown, shining. Soils. Very sectile. Unctuous to the touch, n = O'o. G = 2779... 3700. Conducts electricity. In the matrass yields water. The reactions before the blow pipe are the same as those of oxide of manganese.

Is found at Elbingerode and Iberg in the Harz, Kemlas and Arzberg in Franconia, Siegen, Nassau, Huttenberg, Friesach, Lobcn and other places in Carinthia, Piedmont, in France at Cantern, Groroi in the department of Mayenne, Vic- -dessos in the department of Arriege, Cornwall and especially in the manganese pits of Upton Pyne in Devonshire. 153. ASBOLANE.—Earthy cobalt; Phillips. Cobalt oxide noir; Hauy. Untheilbarer Psilomelan-Graphit; Mobs. Ko- baltschwarze ; Ilausmann. Asbolan; Haidinger. Amorphous. Fracture conchoidal. Opaque. Lustre resin ous, glimmering... dull. Blueish and brownish-black... blackish- blue. Streak black, shining. Soils slightly. Sectile. n = ro... 1'5. G = 22. In the matrass yields water having an empyreumatic smell. Before the blowpipe on charcoal emits a smell of arsenic, but does not melt. A small quantity imparts a violet colour to borax in the outer flame, and a smalt-blue colour in the inner flame. (Co,Cu)Mn’H 4 .
