ORES OF ANTIMONY. 223 



or quartz. Its most celebrated localities are at Schemnitz, 

 Kremnitz, and Felsobanya, in Hungary. It also occurs in 

 the Hartz, Auvergne, Cornwall, Spain. 



In the United States, it has been found sparingly at Car- 

 mel, Me., Lyme, N. H., and at " Soldier's Delight," Md. 



Uses. This ore affords nearly all the antimony of com- 

 merce. 



SULPHURETS OF ANTIMONY AND LEAD. ' 



There are several sulphurets of antimony and lead, all of which fuse 

 very easily, giving off white fumes, with a sulphur odor, and covering 

 the charcoal with yellowish oxyd of lead. The color and streak are 

 between lead-gray and dark steel-gray. 



Jamesonite. Occurs in right rhombic crystals, and also fibrous or 

 columnar. M : M=101° 20'. Streak and color steel-gray. H=2 — 

 2"5. Gr=55 — 5'8. Contains antimony 36 per cent., lead 44, and 

 sulphur 20. From Cornwall, Siberia, and Hungary. 



Feather ore. In fine capillary crystallizations, like a cobweb, or piu- 

 mose. Color dark lead-gray. Contains antimony 31, lead 50, sulphur 

 19. From the Eastern Hartz. 



Boulangerite. In plumose masses. Color bluish lead-gray. H= 

 2'5. Gtf±=5'97. Contains antimony 24-1, lead 58-0, sulphur 18. From 

 Molieres in France ; also from Lapland and Russia. 



Plagionite. In oblique rhombic crystals. M : M=120° 49'. Color 

 blackish lead-gray. Brittle. H=25. Gr=5'4. Contains antimony 

 38, lead 41, sulphur 21. From Wolfsberg in the Hartz. 



Zinkenite. In hexagonal prisms ; also fibrous and massive. Color 

 steel-gray. H=3 — 35. Gr=-53. Contains antimony 44, lead 35, 

 sulphur 22. From Wolfsberg in the Hartz. 



Geocronite, Kilbrickenite. Massive, with an imperfect cleavage, and 

 also granular. Color light gray. H=2 — 2*5. Gr=6'4 — 6b. Con- 

 tains antimony 16*7, (which is sometimes partly replaced by arsenic,) 

 lead 67, sulphur 165. From Gallicia, Kilbricken in Ireland, and Sala 

 in Sweden. 



Kobellite. Radiated like gray antimony. Gr=63. Contains 33 

 per cent, of sulphuret of bismuth, along with 46 of sulphuret of lead, and 

 13 of sulphuret of antimony. From Hvena in Sweden. 



Steinmannite. In cubes with cubic cleavage, and massive. H==2 5. 

 Gr=683. Color lead-gray. Affords before the blowpipe fumes of 

 sulphur and antimony, and a globule of lead containing silver. 

 Besides these, there are also — 



Berthierite, (called also haidingerite,) which resembles gray antimony, 

 but contains 27 per cent, of sulphuret of iron with sulphuret of antimony. 

 Another species contains 15 per cent, of sulphuret of iron. From 

 Chazelles in Auvergne. 



Arsenical antimony. Granular, massive ; color tin- white or reddish- 

 ray. H=2 — 4. Gr=62. Composition, antimony 36'4, arseuwj 



3*6. From Allemont and Bohemia.
