(See '' Report on Kerosene Shale and Coal Seams in the 

 Parish of Preolenna," by W. H. Twelvetrees, 1903.) 



The pelionite of Barn Bluff is a somewhat similar 

 material, but it has not been discovered in situ; it is only 

 known as loose surface fragments of varying size. 

 Mr. W. A. Dixon, F.I.C., of Sydney, New South Wales, 

 states: — " Coal of this quality should be of value for gas- 

 making, but it will be of little use for oil-making, as it 

 would yield more tar than oils, which would be difficult 

 to purify. I am satisfied from its appearance, and 

 behaviour when subjected to heat, that it would give rather 

 aromatic hydrocarbons (benzine, napthalin, &c.) than fatty 

 ones (olefines and paraffin). It is not a cannel (from which 

 oils are not made) and not a shale (from which they 

 are made). I would be inclined to name the mineral 

 ' pitch coal,' as being most expressive of its appearance." 



Average of analyses made by Messrs. Dixon, Ward, 

 Sharp, and Newberry gave the following results, viz. : — 

 Fixed Carbon. Gases, &c. Ash. Sulphur. Water.

170. Knoxvillite (Sulphate of Chromium, Iron, and 



Aluminium). 



Occurs as a granular sugar-like substance of a pale-green

 The identification is somewhat doubtful. 



171. Kermesite (Oxy sulphide of Antimony). 



Occurs in attached tufts of radiating capillary crystals, 

 which are usually of a shade of red. It has been obtained
