yellow. It has been reported to occur in small quantity 

 at what was known as the Washington Hay Silver Mine, 

 Heazlewood. 



161. Iron, Meteoric (Iron, Nickel, dc-c.J. 



This element is only known to occur in this State in the 

 meteoric form, of which three occurrences have been 

 recorded, viz. : — 



1. The Blue Tier Siderite. — This is a comparatively small 

 meteorite, weighing but 3 lb., which was found at the Blue 

 Tier, East Coast. (Catalogue of Tasmanian Minerals, 

 1893.) 



2. The Castray Siderite. — A diminutive specimen, weigh- 

 ing only 51 gr., that was obtained by a miner in 1899, with 

 two others of similar size, when ground-sluicing auriferous 

 drift on the banks of the Castray River, a tributary of 

 the Heazlewood River. (Pro. Roy. Soc. Tas., 1900.) 



3. The Lefroy Siderite. — This is a still smaller specimen, 

 whose weight is but 3328 grains. It was found by a pro- 

 spector in testing a dish of alluvial drift for gold at Lefroy 

 in 1904. (Pro. Roy. Soc. Tas., 1905.) 



162. I serine (Titaniferous Iron Sand). 



Abundant in many localities; Pieman River; south of 

 Macquarie Harbour ; Beaconsfield ; Lisle goldfield. 



163. IvAARiTE (SiJicoiitanf'te of Oalciuni and Iron). 



This is a very dark-coloured and garnet-like mineral, 

 which is of complex composition, but rich in titanic acid. 

 It is normally, when in a fresh undecomposed condition, of 

 high lustre, intensely black, and quite opaque. It is an 

 extremely rare mineral in nature, and is apparently 

 restricted to the elaeolite rocks. In this State it occurs in 

 the form of small crystals, which are commonly in a high 

 state of decomposition to a brownish-coloured substance, 

 and are irregularly scattered in considerable numbers 

 throughout the elasolite-syenite porphyry of Port Cygnet. 



164. James ONiTE ( Sidjjhant imonite of Lead). 



Occurs in somewhat large quantity at the Silver Cliff 

 and the old Waratah mines at Mt. Bischoff. At this local- 

 ity its common mode of occurrence is filiform and amor- 

 phous, the entangled fibres often forming large masses of 

 a dark, almost black colour. At the Madame Melba Mine
