Ehombic:Occurs crystallized in regular six - sidedprisms, mostly modified on the terminaledges, sometimes on the lateral; and inacute and obtuse double six-sided pyramids,with triangular planes; massive, and occa-sionally in pseudomorphous crjstals. Colourand streak blackish lead-grey, often tar-nished black, and occasionally metallic. Structure perfectly lamel-lar, sometimes sectile and soft. Eractureconchoidal. Slightly malleable, and muchmore easily fusible than copper. H. 2-5 to 5-5 to 5-8. See 2Sail-headed Coppek- Fig. 128 Fig. 129. Comp. Bisulphide of copper or -G-u S =sulphur 20, copper 80 = 100.

Forms a blue solution in in Cornwall, the finest specimensin the neighbourhood of St. Just; also inAyrshire; in the porphyritic district of Bar-rack Mountain, in Ulster, and massive atKenmare Mines, Kerry. The compact andmassive varieties occur in Siberia, Hessia,Saxon}^, and the Bannat, and at the minesnear Angina, in Tuscany, Copper Glance is met with in veins and I COPPER accompanied by other ores of copper,and is highly prized by the miner; but itis rather a scarce ore of copper, and does notoccur in very great abundance, although itis found in many different places.
