10. Scheelite. 
I have observed in North Carolina several new localities of 
this mineral. 
a. At the so-called Dutchmen Vein of the Bangle mine prop- 
erty, Cabarras county, it has been met with between 90 and 100 
feet depth, associated with pyrites and chalcopyrite in quartz; 
forming an ore, which contains from 2 to 8 ounces of fine gold 
in 2000 pounds, Although it is considerably disseminated 
through the whole mass of ore in fine grains, the largest masses, 
which I have seen were not over $ths of an inch in diameter. 
No crystals have been noticed, but only granular masses of 
a pale yellowish brown color, distinctly showing the octah 
cleavage. It contains: 
Binoxyd of tin, - - - - - O18 
Teint acid,  - . . 3 - 952 
Oxyd of copper, : - - - - 008 
Sesquioxyd of iron, - - - - 018 
Lime, - - - - - 1931 
99°22 
b. Another locality is at the Flowe mine, Mecklenburgh 
county, N.C., where it is associated with barytes, chalybite, 
pyrites, chalcopyrite, wolfram and rhombic tungstate of lime. 
Not more than two crystals have been observed; the first be- 
ing a modification of the octahedron 1, slightly truncated by 1. 
It has a yellowish brown color and would, if perfect, have @ 
leugth of ,%, of one inch; the other crystal was about half that 
size, had a fine orange color and was a combination of the planes 
and a; it contained a small quantity of tungstate of baryla- 
Both crystals gave B.B. traces of tin. 
11. Rhombic Tungstate of Lime. 
Found also at the Flowe Mine. 
It has a yellowish and greyish white color, and a vitreous lus- 
tre, which is subadamantine on a fresh fracture 
d 
Are these crystals pseudomorphs? I do not believe it, at any 
rate, they have not the appearance of pseudomorphs. Wek! 
that lime is isomorphous with oxyd of iron and manganese, 
would therefore suggest that tungstate of lime is dimorphous, and 
that in this case it is coating a nucleus of (Ma)O> WO,, just 
like a chrome-alum crystal, when placed into a solution of alum,
