notes on some new south wales minerals. 365 



Silver. 



Leaf silver on schist from Sunny Corner. 

 Crystallized silver on silver chloride from Lewis Ponds. 

 The Revd. J. Milne Curran informs me that he has found silver 

 in scales on redruthite at the Cobar Copper Mine. 



Silver Chloride = AgCl. 



From Silverton, fairly well formed branching groups of crystals. 



All the New South Wales silver chloride specimens which I 

 have examined so far, contain iodine, some only traces, but others 

 a fair percentage. 



Stannite, Tin Pyrites. 



Mr. Theodore Ranft informs me that he found this mineral in 

 the Ottery Lode, Tent Hill, New England. 



Tellurate of Bismuth — Montanite. 



The specimens were presented to me by Mr. R. Atkinson Price 

 of Market Street, and obtained from Captain's Flat ; the first 

 specimens which came under my notice were I believe from the 

 same place, and were shown to me for identification by Mr. C. S. 

 Wilkinson, F.G.S., early in June last, they have since been 

 described by Mr. Mingaye, before the Chemical Section of the 

 Australasian Association for the Advancement of Science, Vol. i., 

 1888. It is reddish-brown, with dirty orange coloured mineral, 

 soft, and very like certain stalactitic brown haematite, waxy 

 centre, soft and brittle. Associated with it is tetradymite (a 

 telluride of bismuth) and tellurium ochre. 



Topaz. 



Water worn crystals and fragments from Scrubby Gully, New 

 England District. Some are of fair size, clear, free from flaws, 

 and would cut very well. 



Exhibit. 



Californian Batea, or Gold Prospecting Dish. — The 

 Californian batea is a wooden dish for gold prospecting ; this is 

 much more convenient and useful than the ordinary gold prospect- 

 ing tin dish, and is generally used in America in preference. It 

 is conical in section, and all the gold and heavy minerals can 

 readily be collected in the apex of the conical cavity, and the gold 

 if necessary taken up by a few drops of mercury. The grains of
