Moisture not determined. The hardness is 2'5 ; 

 specific gravity approximately 55. Streak, pale 

 yellow. Crystallographic system hexagonal. 

 Before the blowpipe on coal it readily affords 

 a bead of metallic lead with arsenical coating 

 and odour. Imparts to salt of phosphorus bead 

 in OF and EF a fine green, thus absolutely 

 masking the reaction of V^, O- in the OF with 

 this reagent. In the wet the reaction of V., O5 

 was only obtained with difficulty, following the 

 method of Ohly (analysis of the rare metals). 

 The powdered substance was mixed with sodium 

 carbonate, then fused, and after the addition of 

 potassium nitrate lixiviated with water, filtered, 

 and the clear solution boiled with ammonium 

 carbonate. Acidified with hydrochloric acid, and 

 hydrogen sulphide passed through the filtrate, the 

 precipitate gave arsenic and green solution. 

 The filtrate with concentrated ammonium of equal 

 volume and treated with hydrogen sulphide 

 gave a black precipitate which on filtering the 

 solution left a cherry-red solution = vanadium. 

 This new mineral species has been named in 

 compliment to my old and respected friend, Mr. 

 W. R. Bell, the veteran prospector, whose 

 exertion has done much to advance the mining 

 industry of this State, and who moreover has 

 always taken a great interest in its mineralogy 

 and geology. 



Locality — The upper workings of the Magnet Silver 

 Mine, Magnet. 



3 Cloanthite. — {Nickel diarsenide.) 



A greyish white isometric nickel ore, remarkable 

 for readily altering or sweating on the surface, 

 when specimens are in a moist atmosphere, to 

 the hydrated arsenate, which on giving off its 

 excess of hygroscopic moisture apparently becomes 

 annabergite. It occurs in limited quantity with 

 other nickel minerals in the lower levels of the 

 Long Tunnel Mine, Rocky River. 



4 Energite. — {Co'p'per sulyJiar senate.) 



Occurs in limited quantity with other ores of 

 copper. North Lyell Mine, Mt. Lyell. 



5 ExcHERiTE. — {Basic calcium aluminium and iron 



silicate.)
