topaz, sliorl, quartz, and sometimes mica; fine Brazi¬ 
lian topazes, yellow and pink, imbedded in rock crystal, 
&c.;—also the pyrophysalite fromFahlun in Sweden, and 
the pycnite , formerly considered as a variety of beryl, are 
referable to topaz;— chondrodite (maclurite, brucite), 
from New Jersey, and from Pargas in Finland. 
The rest of this Case is occupied by oxide of tita¬ 
nium and titanates ;— rutile , also called titan-shorl, 
massive, crystallized, and fibrous, to which belongs 
the reticulated variety with golden varnish, from 
Moutier near the Montblanc ; acicular and capillary 
crystals of rutile in rock crystal, from Brazil, &c.;—the 
anatase , or octahedrite, from Bourg d’Oisans;—the si- 
lico-titanate of lime, called sphene or titanite , among 
the varieties of which are those called brown and yel~ 
low menakan-ore, in large crystals, from Arendal in 
Norway, and that from St. Gothard, denominated ra- 
yonnante en gouttiere by Saussure, on feldspar with 
chlorite, &c.;—titanate of lime with titanate of ura¬ 
nium, &c. called pyrochlore , from Fredriksvarn in 
Norway;— titanates of iron, to which belong the nigrine , 
iserine, ilmenite , and most of the volcanic and other 
specular iron with glassy fracture;— crichionite , broo • 
kite , polymignite , &c. 
Case 40. Columbates:— columbite or tantalite : a 
portion 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 sul- 
phuret 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 zunder - 
er.tz (tinder ore).
