SOME NEW SOUTH WALES SILVER AND OTHER MINERALS. 233 
Anglesite a sulphate).—Occurs under much the same 
circumstances as the cerussite, and at times the crystals, although 
usually ssi, are brilliant and well formed. 
Fahlerz, occurs at South Wiseman’s Creek Mine in the Bathurst 
Silver 
England, at the latter mine a few small crystals have been met 
ith. Similar antimonial and arsenical silver ores were worked 
at Boorook and other places near Tenterfield. 
At Webb’s Mine the ee occurs with galena, copper 
sulphides, green fluor-spar, 
Manganese.—A. mineral which looks like Semper occurs at 
the Broken Hill Mine, and was met with at a depth of 6ft. in 
cutting a trench on the outcrop of the lode. Tei is smooth, black, 
and shining in mammillated stalactitic form, and upon its ‘surface 
erystals of silver chloride have been rent in hice cases. The 
smelting the silver ores ; on en he found it “98 contain 19-00 
per cent. lead, probably present as carbona cent. 
silica ; 37°88 per cent. manganese (enetalze); ‘prokatly pr cab 
as dioxide ; 3-02 per cent. alumina; 2-97 per cent. iro 
Another specimen which he also partially analysed, from the South 
—_ Hill Mine, about } mile south of the outcrop whence 
the previous one was found, yielded 6°20 per cent. silica ; 23°85 
per cent. iron; 21° er cent. manganese, probably ‘present 
as dioxide; 14:00 per cent. lead, probably present as carbonate. 
ge both contain lime, &e., but the other elements have not been 
estim 
Cassiterite —Some large well developed crystals of bro 
tinstone in quartz, about 14 inch in diameter, from. J sepa 
Mine on the Upper Murray. 
Zincite.—Red oxide of zinc, mistaken by local minersfor calamine, 
from the Vegetable Creek, New Englan 
T 2.—Fairly well crystallised topaz from Scrubby Gully, 
New England, from 4 inch to 1} inches long. 
Beryl.—A_ rolled “fragment of about } “inch x $ inch, not of 
very good colour, and muc 
Garnets.— Common red, crystallised in chlorite, from New 
England. 
Diamonds.—In twin eee of imperfect three-faced octohedra, 
united by a plane parallel to a face of the octohedron. Sent by 
Mr. C. 8. Wilkinson; beatiie from the Sydney Diamond Mining 
Company, near Inverell. A collection of minerals accompanying 
the diamonds in the Bengonoway Diamond Mine, is also exhibited. 
Although these are somewhat the same as occur at Bingera there 
are well marked and characteristic differences.
