sAlooN. Cornwall, nearly pure, mixed with copper py- 
nat. Hist. I’ites, &c.;—among the specimens of common 
tinstone are, the regular and macled crystals, 
the pebble-like and granular tin stone (shoad 
tin, stream tin, grain tin, See.)? and the greyish- 
white crystals, resembling scheel ore, or tunsgate 
of lime; the tin stone from Finbo, in Sweden, 
which contains oxide of tantalum.—The ores of 
tungsten, which frequently accompany those of 
tin, are— wolfram(^QheeYm ferrugineuxof Haiiy), 
crystallized and massive, from Bohemia, &c. and 
the tunsgate oflime^ scheel ore (scheelin calcaire 
of Haiiy), among the crystallized specimens of 
which is the primitive acute octahedron from 
Allemont in Dauphine.—In this case are also 
placed the specimens of molybdena, or sulphuret 
of molybdenum, which should not be confounded 
with graphite; the yellow powder on feldspar, 
from Westmania in Sweden, in oocide of molyb¬ 
denum. 
Case 46. Part of this case is occupied by the 
ores of titanium, viz, the oxides, called titdnite, 
brown-ore, brunon (sphene, and titane siliceo-cal- 
caire of Haiiy), among the varieties of , which is 
that in large flat octahedral crystals from Nor¬ 
way, with epidote, &c. also the variety called, 
by Saussure, rayonnante en gouttiere, from St. 
Gothard, on feldspar, with chlorite, &c.— Titan- 
shorl, also called rutile ; massive, crystallized, 
and flbrous, to which latter belongs the variety 
with golden tarnish, from Moutier, near the 
Montblanc;
