As a last representative of this group may be mentioned a 

 tomahawk of a dark green indurated diabasic tuff in the Mining 

 and Geological Museum, from Dilga West, of an elongately oval 

 shape. It has been a pebble, much weather-worn on the surface, 

 and was evidently selected by its owner on account of the appro- 

 priate shape of the pebble, the only reduction it has undergone 

 being a little chipping at the butt, which is square ended. The 

 cutting edge is limited, and the bevel angle low. The measure- 

 ments of this stone are : — Length, 4 Jin. ; breadth, 2fin. ; thick- 

 ness, If in. ; weight, 21b. loz. 



2. Ovate Type. By this form I intend to convey the impression 

 of a tomahawk, less elongated transversely than in Type 1, and 

 wider in proportion in a contrary direction, but still too long to 

 be absolutely oval. Such implements are also usually larger. No 

 better example of this form can be taken than one in Sir W. 

 Macleay's Collection, formerly exhibited by Mr. J. G. Griffin, f 

 and said to have been dredged from the Hawkesbury River. 

 It is a pebble of diabasic dolerite, quite untouched with the 

 exception of the ground bevelled edge, the remainder of the 

 surface being smooth and unpolished. The bevelled edge does 

 not show the same amount of finish as many other implements of 

 a similar nature, as the scratches arising from the process of 

 grinding still remain, and have not been removed by the after 

 process of polishing which many aboriginal tomahawks certainly 

 have undergone. The scratches in question show that the friction 

 employed to produce the bevelled edge was not confined to one 

 direction, for some of the stride are in that of the longer axis, 

 others in that of the shorter, and a third set have an oblique
