[long 
topaz ;—ehondrodite (maclurite, brucite)- from New Jer¬ 
sey, and from Pargas in Finland. 
The rest of this Case is occupied by oxide of titanium 
and titanates ;— rutile , also called titan-shorl, massive, 
crystallized, and fibrous, to which belongs the reticulated 
variety with golden varnish, from Moutier near the Mont- 
blanc ; acicular and capillary crystals of rutile in rock 
crystal, from Brazil, &c.;—the an at as e, or octahedrite, 
from Bourg d’Oisans;—the silico-titanate of lime, called 
sphene or titanite , among the varieties of which are those 
called brown and yellow menakan-ore, in large crystals, 
from Aren dal in Norway, and that from St. Gothard de¬ 
nominated rayonnante en gouttiere by Saussure, on feldspar 
with chlorite, &c. :—-titanate of lime with titanate of ura¬ 
nium, &c., called pyrochlore , from Fredriksvarn in Nor¬ 
way;— titanates of iron , to which belong the nigrine , ise- 
rine , ilmenite , and most of the volcanic and other specular 
iron with glassy fracture;— crichtonite , brookite , polymig - 
nite , &c. 
Case 40. Columbates :—columbite or tantalite : a por¬ 
tion of the specimen from North America, in which Mr. 
Hatchett discovered the metal; variety of the same from 
Rabenstein, Bavaria, accompanied by beryl and uranite ; 
—the Finbo - and the Brodbo-ta?italites of Berzelius;— 
yttroiantalite , from Ytterby. 
Oxides of antimony and antimoniates :— antimony-ochre 
on native and grey antimony ;—white antimony , formerly 
considered as a muriate: on galena, quartz, &c .;—red 
antimony (a combination of oxide and sulphuret of this 
metal), mostly in fine capillary crystals, from Braunsdorf 
in Saxony, Malazka in Hungary ; and an argentiferous 
variety from the Hartz, in fibrous flakes resembling tinder, 
and therefore called zunderertz (tinder ore). 
Tungstates :—tungstate of lime (scheelin calcaire of 
Haiiy), also called scheelite and tungsten (heavy stone), 
among the more interesting specimens of which is the pri¬ 
mitive acute octahedron from Allemont in Dauphiny ; 
—tungstate of iron and manganese or wolfram , massive 
and crystallized, from Bohemia and other countries ; also 
as octahedral supposititious crystals, derived from tung¬ 
state of lime ;—tungstate of lead , or scheel-lead ore , from
