MIKERALOGY. 465 



Awaruite. — A kind of nickeliferoiis native iron found in the drift of 

 the Gorge Riv'er, which empties into the Awarua, or BigBay, on the west 

 coast of the middle ishmd of ^N'ew Zeahtnd. It is believed to have been 

 derived from a peridotite, now altered largely into serpentine, and is 

 associated with gold, platinum, cassiterite, chromite, magnetite. Its 

 hardness is about 5, and the specific gravity S.l. The composition is 

 expressed by the formula FeNig, as shown by an analysis by W. Skey, 

 viz : 



Ni Fo Co S SiOa •

This terrestrial uickeliferous iron is closely allied to the similar me- 

 teoric mineral which has been called octibbeiiite, found in Oktibbeha, 

 County, Mississippi. (Described by G. H. F. Ulrich in Amer. Journ. 

 Sci., 1887, xxxiii, 244.) 



BarJceviJcite, etc. — In a preliminary account of the results of an ex- 

 tended study of the minerals of the augitesyeuite and elieolite-syenite 

 veins of Southern Norway, W. (J. Brogger has given brief accounts of 

 a number of new species. Full descriptions are promised later. The 

 names of these are, harJcevikite, caleiothorite, melanocerite, nordenaJciohUne, 

 rosenbuschite. They are characterized briefly as follows: 



Barlcenikite is a mineral belonging to the amphibole group, and most 

 closely related to arfvedsouite ; it is distinct, however, in optical char- 

 acters. 



Calciothoritc is a hydrous silicate of thorium and calcium, and it is 

 inferred, as seems very probable, that it is an alteration product of an 

 original thorium silicate (ThOjSiO^) ic>omorphous with zircon. Thorite, 

 orangite, eucrasite, freyalite, are other hydrous silicates that probably 

 have had a similar origin. 



Melanoccrite is a complex silicate of the cerium metals, yttrium and 

 calcium, with other substances in small amounts, including 3 per cent, 

 boron trioxide. It occurs in dark-brown crystals, belonging to the 

 rhombohedral system, and tabular in habit. 



Nordenshioldine, named after the Swedish mineralogist and explorer, 

 A. E.Xordeuskiold, is a mineral of remarkable composition, viz, a borate 

 of tin and calcium, CaO.SiiOuB203. It has a sulphur-yellow color ; its 

 hardness is 5.5 to G, and its specific gravity 4.20. It appears in tabular 

 rhombohedral crystals. 



Bosenhuschite, named after Professor I^osenbusch, of Heidelberg, is a 

 silicate of calcium and sodium with zirconium, titanium, and lanthanum 

 in small amount. It belongs to the mouoclinic system and its crystals 

 are near wollastonite and pectolite in angle, and it is accordingly called 

 azircouium-pectolite. The color is orange-gray; the hardness is 5 to G, 

 and the specific gravity 3.30.
