52 THE MINERALS OF TASMANIA. 



has been identified as anthracite by Mr. F. Danvers Power, 

 F.G.S., and as a variety of lignite by Mr. A. Montgomery, 

 M.A., Government Geologist, and Mr. W. F. Ward, 

 A.R.S.M., Government Analyst (" Notes on a Carbonaceous 

 Deposit in Silurian Strata at Beaconsfield, Tasmania," Pro. 

 Australasian Association for the Advancement of Science, 

 1892). The material is from a dark-brown to an entirely 

 pitch-black colour, extremely pulverulent, shining, and 

 has occurred at times in rather large quantity. 



Messrs. Montgomery and Ward state (loc. cit.): — "Two 

 main lines of quartz reef traverse the Cabbage Tree Hill, 

 one worked by the Amalgamated West Tasmania, Moon- 

 light, Olive Branch, and Little Wonder, in all of which 

 mines the substance has been obtained. It occurs in the 

 Tasmania in hard beds and patches of a coarse quartz grit 

 in the principal workings of the mine; in the Moonlight 

 at a depth of over 422 feet from the surface. It is also 

 found in the cracks and joints of the gritty masses to quite 

 90 feet below the present sea-level." Messrs. Montgomery 

 and Ward consider that the substance is not older than 

 the Tertiary epoch, but it may be of much greater 

 geological age. 



" The average composition was found by analysis to be as 

 follows : —

87. CoBALTiTE (Arsenide of Cobalt and Iron). 



This mineral occurred in small patches, with pyrites, 

 galena, and grey copper ore, at the old Penguin Silver 

 Mine, Penguin River (James Smith). It has also occurred, 

 but in very small quantity, embedded in schist near Lake 

 Dora. 



88. CoPALiTE (Fossd Resin). 



A brownish-yellow, hydro-carbonaceous substance with 

 a semi-pearly sheen. It is very brittle, soft, and of uneven 

 fracture. When heated it melts to a dark-brown varnish- 

 like mass, burning with a yellow flame, during which it
