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 anatase, 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 Arendal ill 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;— cricktonite, brooldte, polymig - 
nite, &c. 
Case 40. Columbates :— colimbiie 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-tantalites of Berzelius;— 
yttrotantalite, 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 
Plaiiy), 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
