8. Native Tin; by M. Hermann, (Jour. f. Prakt. Chem., Xxxxiii, 
300.)—According to Hermann, native tin oceurs in the gold washings of 
: the Ural, in small gray metallic grains containing also some lead. 
| 9. Turgite; by M. Hermann, (Jour. f. Prakt. Chem., xxxiii, 96.)— 
‘Targite is a hydrated peroxyd of iron from the Ural, of a brownish-red 
color, 3:54 to 3°74 specific gravity, consisting of peroxyd of iron 85°34, 
Water 5:31, oxyd of lead and copper 1°85, gangue 7°50, formula 
QF ot er. 
10. Bodenite ; (Poggend., Ixii, 686 ; Berz. Jahresb., xxv, 1845, 365.) 
—Breithaupt has given the name Bodenite, derived from the locality, 
Boden in Saxony, to a mineral resembling orthite, containing cerium. 
1]. Parisite, a new cerium mineral ; by M. Bunsen, (Ann. der 
Chem. und Pharm., 1845, No. 2. )—Parisite was discovered by M. Paris 
in the valley of Musso, New Grenada. It occurs crystallized in bipy- 
ramidal dodecahedrons; the basal angles are 164° 58’, and the lateral 
i of the pyramid 120° 34’. It cleaves easily, parallel to the base; hard- 
- hess between fluor and apatite; specific gravity =4:350; color reddish 
brown; fracture vitreous and conchoidal; transparent in thin fragments. 
Heated it loses water and carbonic acid and becomes friable. It is in- 
fusible and phosphorescent before the blow-pipe. Composition, car- 
bonic acid 23:51, protoxyd of cerium, Jantanum and didymium 59°44, 
_ lime 8:17, fluorid of calcium 11-50, water 2°38=100-00, | 
_ 12. Saccharite ; by M. Scumipr, (L’Institut, No. 549, p. 227.)—Sae 
- Charite resembles somewhat a granular feldspar, and is from Silesia. 
At is either white, or greenish from a mixture with pimelite. Specific 
gravity 2-668. It is infusible before the blowpipe alone, and with great 
difficulty with soda... M. Schmidt obtained in his analysis, silica 58°93, 
alumina 23:50, peroxyd of iron 1-27, oxyd of nickel 0°39, lime 5°67, 
magnesia 0-56, potash, 0°05, soda 7°42, water 2°21. Excluding the 
water, it gives the formula R* Si?-+-3RSi?, which is identical with that 
of leucite, a 
13. Fischerite ; (Berz. Jahresb., xxv, 1845, 390.)—Fischerite is a 
Phosphate of alumina (Al® P*) containing, according to M. Hermann, 
24 equiv. of water (24E2). It comes from Nischne Tagilsk, in the Ural, 
Where it occurs of a dull green color and translucent ; specific gravity, 
*46. It is sometimes met with in transparent six-sided prisms. 
14, Turquois.—M. Hermann finds that the blue Turquois has the for- 
mula Al? P24 Al+ 15H. 
15, ee fe mineral; by A. ExpMaNnn, ( Kongl. Vet. Akad. 
_ -*andi., 1845.)—Keiihauite was found near Arendal, in Norway, ina 
feldspathic rock. It is massive, of a brownish-black color, and grayish-
