The sulphide commonly known as Stannite (Dana “ A Text- 
book of Mineralogy,” 1885) is almost, if not quite peculiar to 
Cornwall, and has not so far been detected in this island. 
This mineral is reported to occur in North Queensland and in 
New England, New South Wales. (‘ Report of the Second 
Meeting of the Australasian Association for the Advancement of 
Science, 1890,” pages 215 and 260.) 
207. STERNBERGITE (Argento-pyrite). 
This species occurs with Huastolite and Galena in the workings. 
of the Godkin Extended mine, at Heazlewood. An assay of a 
fairly pure specimen gave a very high return in Silver. 
208. SPINEL, BLACK—See PLeonasteE. 
209. SCHEELITE (Tungstate of Calcium). 
At Mount Ramsay this occurs in the characteristic mineral- 
bearing hornblendic rock of the locality. It is found in well- 
formed crystals of considerable size, often up to one inch in length, 
and crystalline bunches. The colour is usually pale yellowish- 
brown, and in good specimens the facets are polished ; in tabular 
crystals which are nearly white, Upper Emu River, in Garnet 
rock. (W. R. Bell.) 
210. SMALTINE (Arsenical Cobalt). 
Usually obtained in solid masses with a cubical fracture and of 
tin-white colour. It is said to occur in an almost solid vein or 
small lode at the North Pieman, also at the Hampshire Silver 
mine ; in limited quantity, Penguin River; Castles Forbes Bay 
(Johnston, “ Geology of Tasmania’); Mount Heemskirk with 
Cassiterite. 
211. SAPPHIRE—See Corunpum. 
212. SPHALERITE (Zine Sulphide or Blende). 
This mineral is of frequent occurrence, but not in great 
abundance at any of its many localities. It is often met with in 
comparatively limited quantity in the Silver-lead mines of Zeehan, 
Dundas, the Heazlewood, and at Ben Lomond. At the Silver 
Crown mine at Zeehan, bunches of somewhat large crystals occur 
of a brown colour; at the Godkin mine, Whyte River, a richly 
argentiferous Blende occurs in amorphous masses,—it is of a 
mahogany-brown colour with a dull lustre. It is found associated 
with patches of Native Silver and masses of Galena in a white 
and dark-coloured Calcite, and more rarely in Ankerite; at the 
Healzlewood Silver-lead and other mines in the vicinity, minute 
but remarkably well formed crystals are very abundant. They 
are of a clear yellow to red colour, and are usually obtained 
implanted in the fractures of Siderite or Quartz with crystals of
