Montblanc ; the acicular crystals of rutile in 
rock crystal, &c.; the ferriferous oxides {sidero- 
titanium of Klaproth), some varieties of which 
may be considered as titaniferous oxides of iron, 
and to which may be referred the black sand 
called menachanite, and the iserine, in loose 
grains and imbedded ;—specimens of anatase^ or 
octahedrite, from Dauphine :—the same, toge¬ 
ther with a scarce substance called crichtonite 
(craytonite of Bournon), which has been con¬ 
sidered by some as a variety of helvine, and as a 
silicate of zirconia by others, but appears to be 
a silicate of titanium. The remainder of this 
table-case contains the ores of antimony ; native 
antimony^ from Allemont, and from Sala in Swe¬ 
den, some varieties of which are arseniferous ; 
—sulphuret of antimony^ or grey antimony (the 
most common ore of this metal), occurs com¬ 
pact, foliated, radiated, and plumose : the more 
remarkable among these are the specimens of 
crystallized radiated antimony in fine groups, 
especially from Transylvania ; radiated grey an¬ 
timony with barytes, realgar, &c., the plumose 
grey antimony, some varieties of which, appear¬ 
ing like delicate wool or down, display a fine 
iridescent blue, yellow and red tarnish ; red 
antimony^ mostly in fine capillary crystals, from 
Braunsdorf in Saxony, and a variety of the same, 
called tinder ore^ from the Hartz \—vohite antU 
mony^ an oxide, formerly considered as a mu¬ 
riate, of this metal, crystallized, on galena, &c.
