THE ARSENIC GROUP. 101 



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

 mel, Me., Lyme, N. H., and at "Soldiers Delight," Md., 

 in the Humboldt mining region, and in the mines of Aurora, 

 Esmeralda County, Nevada. 



This ore affords much of the antimony of commerce. By 

 simple fusion, the crude antimony of the shops is obtained, 

 from which pure antimony and its pharmaceutical prepara- 

 tions are made. 



Allemontite is an arsenical antimony, Sb 2 As 3 , from Allemont, and 

 also from Bohemia and the Hartz. 



Valentinite. White antimony in white, grayish, or reddish rect- 

 angular crystals, with perfect cleavage, affording a rhombic prism of 

 136 ; 58'. Also in tabular masses, and columnar and granular. H. = 

 2 o-3. G.=5o7. Lustre adamantine to pearly. Composition, Sb 2 3 

 =Oxygen 16*44, antimony 83 56=100. 



Senarmontite is the same compound in isometric forms. 



Kermeslte or red antimony is an antimony oxide and sulphide, in 

 red tufts of capillary crystals. Lustre adamantine. From Hungary, 

 Dauphiny, Saxony, and the Hartz. 



Cervantite. An oxide of antimony, Sb 2 4 , resulting from the de- 

 composition of stibnite. 



Livingstonite. Like stibnite, but contains 14 per cent, of mercury 

 and has a red streak. From Mexico. 



Native Bismuth. 



Khombohedral ; R A R—SV 40'. Cleavage rhombohedral, 

 perfect. Generally massive, with distinct cleavage ; some- 

 times granular. 



Color and streak silver white, with a slight tinge of red. 

 Subject to tarnish. Brittle when cold, but somewhat mal- 

 leable when heated. H.=2-2-5. G.=9-?-9-8. Fuses at 

 a temperature of 476° F. 



Composition. Pure bismuth, with sometimes a trace of 

 arsenic, sulphur or tellurium. B.B. on charcoal vaporizes, 

 and leaves a yellow coating on the coal, paler on cooling. 



Obs. Native Bismuth is abundant with ores of silver and 

 cobalt in Saxony and Bohemia, and occurs also in Cornwall 

 and Cumberland, England. At Schneeberg, it forms arbo- 

 rescent delineations in brown jasper. Occurs also in Nor- 

 way, Sweden, Chili and Bolivia ; also at the Balhannah 

 mine, in S. Australia, with copper ore and gold. 



In the United States, it has been found at Lane's and 

 Booth's mine, Monroe, where it occurs with tungsten, galenite 

 and pyrite ; also at Brewer's mine, in Chesterfield district, 

 South Carolina ; and in Colorado.
