placed the specimens of molybdena, or siilpJmret 
of molybdenum^ which should not be confounded 
with graphite : the yellow powder on feldspar, 
from Westmania in Sweden, is ojcide of molyb¬ 
denum. 
Case 46. Part of this case is occupied by the 
ores of titanium, viz, the oxides called titanite^ 
hroxm-ore, brunon (sphene, and titane siliceo-cal- 
caire of Haiiy), among the varieties of which is 
that in large flat octahedral crystals from Norway, 
with epidote, &c. also the variety called, by Saus- 
sure, rayonnante en gouttiere, from St. Gothard, 
on feldspar, with chlorite, &c.— Titan-shorl^ also 
called rutile ; massive, crystallized, and fibrous, 
to which latter belongs the variety with golden 
tarnish, from Moutier, near the Montblanc; the 
acicular crystals of rutile in rock crystal, he, ; 
the ferriferous 03:ides(^siderotitaniumo^lL\^^voi\\\ 
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 Dau- 
phine :—the same, together with a scarce sub¬ 
stance cdiWeA C7''ichtonite (craytonite ofBournon), 
which has been considered by some as a variety 
of helvine, and as a silicate of zirconia by others, 
but appears to be a silicate of titanium. The re¬ 
mainder of this table-case contains the ores of 
antimony : native antimony^ from Allemont, and 
from Sala in Sweden, some varieties of which are 
arseniferous 5
