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 the writer's 

 old respected friend, Mr. W. R. Bell, the veteran pros- 

 pector, whose exertion has done much to advance the min- 

 ing 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. 



42. Beresowite (Chromate and Carbonate of Lead). 



An extremely rare mineral previously only recorded from 

 Berezov, Siberia. At the Magnet Mine it occurs as small, 

 in many cases almost microscopic, lamellae implanted In 

 gossan. In colour it varies from pale-yellow to orange-red. 

 It is at times altered to crocoisite. It is confined to the 

 cracks and vughs in the gossan, where it forms coatings of 

 minute plates and pseudocrystals, which often nestle in 

 little bunches. It not uncommonly decomposes to massi- 

 cot, and is at all times difficult to preserve owing to its 

 slight attachment to the base. Formula for this species, 

 6PbO 3Cr O3 C Og. 



4'^. Berthierite (Sulphide of Antimony and Iron). 



Usually of a dark steel-grey colour, with a metallic lustre 

 and irregularly striated surface. Found in considerable 

 quantity, but low in silver contents. 



Locality : Mt. Bischoff. 



44 Beryl (Silicate of Aluminium, and Glucina). 



The true emerald has not so far been found here, but 

 hexagonal prisms which are colourless to bluish-green have 

 been obtained at Flinders Island ; and also waterworn 

 pebbles, in stanniferous drift, at Mt. Cameron. At the 

 last locality a fairly good example was obtained some years 

 ago. It consisted of portion of a crystal about an inch 

 in diameter and the same in length ; it had the true 

 hexagonal form and characteristic cleavage, and the colour 

 was dull-green with a translucent appearance. The stone 

 was mistaken by the miners for a peculiar form of copper 

 ore. More recently another specimen was obtained in the 

 drift of almost the same colouration, rather less in
