1040 General Notes. 
esite, galena, chalcopyrite, argentite, proustite, etc., there oou 
small, steel-like crystalline forms of radiated structure, often stel 
late, which have been shown by W. F. Hillebrand! to be a ca l 
tiferous variety of lollingite,an arsenide of iron. The J 
are often interpenetrated, and form twins and trillings, which agan ‘ 
interpenetrate to form complex radiating masses, several 
inches in diameter. The specific gravity is 7.4, and analyse 
showed the presence of over four per cent of cobalt, with small 
percentages of nickel, copper, bismuth and sulphur. 
A related mineral, which occurred in thin blades with the li | 
lingite, was shown to be an arsenite of cobalt, but not enough | 
was obtained for analysis. | 
Cosalite was found in La Plata county in irregular masses ol 
small size, having irregular fracture, a grayish-white color, and 
hardness o 
A sulpho- bismuthite of copper and silver, probably a nee 
mineral, was found in a quartz vein in Park county. It wasi 
bluish-gray substance, sometimes occurring in minute, slender, 
striated crystals. It will receive further investigation, ; 
Hiibnerite occurs in Ouray county in large a 
vertically striated and imbedded in quartz. A 
black color, pale yellow in tn thin crystals. The oa 
agrees with the formula, MnW 
Evansite.—The rare eels evansite, a phage phosphate o 
alumina, heretofore found only in Hungary, W t5 
brought i in 1856 by Brooke Evans, after whom D. Forbes n 
the species, has recently been found by A. S. Woodware in 
Cheshire, England. It occurs in fissures in a fossiliferous 5 
and it is probable that like the vivianite of the New Jerseys 
sand beds, it is in part derived from organic matter. In pi 
characters the mineral agrees with the original evansite. 
Tin From Norta Carorina.—In a recent number oa the Nar 
URALIST reference was made to the discovery of tin at "i 
mountain, N.C. Dr. C. W. Dabney, Jr., has sent us ut 
ticulars concerning its occurrence at that place.
