62 MINERALS OF TASMANIA. 
Galenite; at the Heazlewood mine it also occurs more rarely, 
in beautiful sharp-angled crystals which have a purple, green, 
and red metallic lustre; abundant in a massive form of a 
black colour, east branch of the Hellyer River; with the 
sulphides of Copper and Lead in an elvan of porphyry, opposite 
Gad’s Hill, Mersey River, (W. R. Bell), plentifully and. thickly 
disseminated in a vein at the Hampshire Silver mine, where it 
presents a peculiar copper-red colouration; Hunterston, on the 
Shannon, near Bothwell, (Pro. Royal Soc. Tas., 1854) ; of a dark 
brown to black colour with Chlorophane and various forms of 
Pyrites, Mount Bischoff; scattered throughout a dyke formation, 
with Galena in Granite rock, Meredith Range ; as minute crystals 
of a pale green colour with Galena, Australasian mine, Dundas ; 
in limited quantity, Ben Lomond ; in a lode which is mainly 
composed of a mixture of this mineral, Arsenopyrite, and Galena, 
Scamander River; Penguin River Silver-lead mine; Mount 
Claude; Middlesex, with Pyrites and Galena; often highly 
auriferous, but in very small quantity, Lefroy and Mathinna; a 
peculiar variety of phosphorescent Blende occurs at the Castray 
River: it was obtained in trenching across a decomposed lode 
formation as rounded lumps, brown in colour, and of small size 
with masses of Galena and Pyrites as accessory minerals. The 
phosphorescent character is clearly distinct when struck or 
scraped with a knife blade. It is locally known as “ Electric 
Calamine.” At Mount Reed with Pyrites and Galena it is some- 
what abundant. 
Sphalerite often contains Gold, Silver, Cadmium, and the rare 
elements Thallium, Iridium, and Gallium. 
213. SCORODITE (Hydrated Arsenate of Iron). 
Formed by the decomposition of Marcasite, and usually found 
where that mineral is abundant. It is commonly met with at the 
Scamander River and vicinity; Golconda; Mount Bischoff; 
in the cavities of siliceous skeleton rock as beautiful green crystals 
at the Upper Emu River ; amorphous in considerable quantity at 
the Waterhouse Gold field, at which locality it has been obtained 
in green-coloured crystals in the ‘Southern Cross” reef; near 
Mount Pelion, in quantity, the masses occasionally showing the 
gradual transmutation from the original mineral Arsenopyrite. 
214. STEATITE (Hydrated Silicate of Magnesia). 
Abundant with Asbestos and Serpentine, Asbestos Mountain ; 
Mount Bischoff; Heazlewood; Beaconsfield; River Forth ; near 
Mount Claude. “The Steatite contains a small vein of Silver, 
which, by the way, is not uncommon in this mineral, and is met 
with in most of the primitive mountains” (Pro. Royal Soc. Tas., 
1854). This note refers to a specimen said to have been obtained 
at the Asbestos Mountain, but I have failed to detect any Silver 
in the numerous examples that I have examined.
