List of Minerals. 



Albite. — Soda felspar. 



Associated with ankerite in silurian slate, Sulienian Pasha 

 Mine, Ballarat East ; associated with ankerite, quartz, 

 pyrite, etc., in silurian slate and sandstone, Band and 

 Albion Mine, Ballarat (B.M.). 



Anglesite. — Lead sulphate. 



A nodule of galenite with a grey massive crust of anglesite 

 mixed with a little cerussite. Upper Silurian limestone, 

 Lily dale (W.). 



Apatite. — Chloro-j)hosphate of calcium. 



Small greenish-yellow hexagonal crystals in a tourmaline 

 granite, hills near Seymour ; long hexagonal crystals 

 from the older basalt, Westernport (W.). 

 Apatite was first noticed in the basalt of Phillip Island, but, 

 owing to the similarity of form, was for some time 

 taken to be Nepheline, and consequently it is recorded 

 as this mineral in some of the earlier catalogues. The 

 correct determination was due to Mr. O. R. Rule. 



Arsenopyrite. — Sulp-arsenide of iron. 



Small simple crystals enclosed in a clear quartz crystal 

 (endomorph), Blackwood (W.). This mineral has such 

 a general distribution that it is useless attempting to 

 record all its occurrences. It is almost as prevalent as 

 pyrite, and occui's in much the same manner in many 

 of our quartz reefs, and also in some of the auriferous 

 dyke rocks when it appears at times in long fine, pris- 

 matic crystals. 



Arsenolite. — Arsenic trioxide. 



All occurrences are artificial and result from the condensa- 

 tion of arsenic oxide, when arsenical ores (arsenopyrite 

 mostly) are being calcined prior to chlorination. 



ASPHALTUM. — 



In small rounded pieces with roughened exterior. Found 

 on the beach of Bullenmerri, near Camperdown. 

 AuGlTE. — var. of pyroxene. 



Acicular crystals in a druse of dolerite, Miners' Racecourse, 

 Ballarat (B.M.).
