72 TASMAXIAN MIXEKALS. 



detected, which are probably this mineral. At the 

 Mount Farrell Mine it has been noticed embedded in 

 galena; also at the Confidence Mine;, near Waratah, 

 and at the Hercules Mine, Mount Read, it has been 

 seen in micro-crystals attached to filaments of native 

 silver. Reported to have been found at the Oonah 

 and British-Zeehan mines at Zeehan. 



The light ruby silver ore (proustite) is sometimes 

 associated with the pyrargyrite ; the latter appears 

 to be the more often noticed, but the exact determina- 

 tion of the species has not been made in the majority 

 of occurrences. 



27 Restormelite {Hych'ous silicate of alinninium. and 



iron.) 

 As at ^s original, locality, Restormel Mine, Cornwall, 

 this substance occurs as a coating on psilomelane 

 and other manganiferous material. It is white to 

 pale-greyish blue, sometimes almost a clear blue. The 

 incrustation is invariably thin, but quite noticeable 

 and distinct. Locality : The Comet Mine, Dundas. 



28 Silver {Jative.) 



Some extremely fine examples of this native metal have 

 recently occurred in the carbonate lode at the Her- 

 cules Mine, Mount Read. The mineral assumes most 

 attractive nests and layers of extremely fine wire-like 

 filaments, often with fern-like expansions, commonly 

 implanted on a glistening, pure white, fibrous ceru»- 

 site. The occurrence is by far the finest of its kind 

 hitherto found in this State. 



29 TuRGiTE {Hydrojts st-sqi/ioridr of iro7}.) 



An iron ore with the general aspect of fibrous horn- 

 stone, with a red streak. Hardness =5. 6. Locality: 

 Blythe River. 



30 Xanthosiderite {Hydrous scsquio ride of iron.) 



Found as an incrustation, often in silky needles of a 

 bright red colour, but sometimes in the powdery 

 form. Occurs in the lode on gossan and other 

 gangue. Locality : Magnet Mine, Magnet.
