4 MINERALS OF TASMANIA. 
separated arsenical pyrites made by Mr. Cosmo Newberry gave a 
return of above three ounces of gold per ton; at Mt. Bischoff and 
at north-east Dundas it is plentiful, intimately mixed with other 
pyrites, the whole containing a considerable quantity of Cassiterite,— 
at the former locality it has been found in a lode formation with 
Fluor-spar, Sphalerite, and Siderite; it is fairly abundant in 
auriferous reefs at Mathinna, Lefroy, and Beaconsfield, also 
Penguin River, Mt. Ramsay, Mt. Heemskirk, Mt. Pelion, and 
other places. 
On the southern slope of Mt. Wellington this mineral is said to 
occur, containing up to 15 per cent. of Cobalt. It was found 
intermixed with quartz in a disturbed contact formation occurring 
between sandstone and altered slate (Dyson Western). This form 
probably belongs to the sub-species Glaucodot. 
7. ADULARIA (a variety of Felspar, also known as Moon- 
stone). 
Occurs in large crystalline masses porphyritically disseminated 
in granite and a dioritic rock. It is usually washy-white, but 
varies to a pale green colour. 
Upper Arthur River; Coldstream Rivulet, a tributary of the 
Huskisson River; and at the Tasman Rivulet, with quartz of 
various forms. (W. R. Bell.) 
8. ANNABERGITE (Arsenate of Nickel). 
This is a secondary mineral of an apple-green colour when 
pure, soft, and commonly massive or incrusting. 
Obtained in extremely minute quantity, Penguin River. 
9. AUGITE (a dark-coloured variety of Pyroxene). 
The crystals of this mineral are usually, if not always, stouter 
proportionally than those of its ally, Hornblende, and they are 
but rarely much elongated. In the basalt rock they are some- 
times fairly developed. 
St. Paul’s Plains (Proc. Royal Soc. Tas., 1854),—in basalt, 
the crystals are often nearly half an inch in length ; Paddy's Sugar- 
loaf, Emu River; Hampshire Hills, near the Emu River; near 
Mount Horror, in an intensely black basalt, on the weathered 
portions of which the crystals stand out from the surface of the 
rock: they are often very clearly defined. 
10. ASBOLITE (Hydrated Oxides of Manganese and Cobalt). 
This unsatisfactory species (?) has been found at the Godkin 
Silver Mine, Whyte River, in bluish-black bunches and irregular 
masses ; occurs fairly plentiful at Dundas; Castle Forbes Bay ; 
Magnet Range, in lode gossan with other secondary minerals ; 
Castra, Upper Leven; Penguin River, and other places.
