Note on three new Localities of Tellurium Minerals in California, and on some Mineralogical Features of the Mother Vein.
BY B. SILLIMAN.
(a.) Tellurium Minerals.—It is well known to mineralogists and others that in the Melones Mine, on Carson Hill, there occurs, in considerable abundance, a tellurium compound which has been called Sylvanite by some mineralogists, but apparently without sufficient authority. It occurs in one of the veins on the Melones property, associated with Dolomite and quartz, in what appears to be a gneissic rock; but the mine being under water I am dependent on the specimens kindly furnished me by the intelligent proprietor, Mr. G. K. Stevenot, for my knowledge of the gangue.
