Thargomindah, presented to the Mining and Geological Museum 

 by Mr. H. A. Maclean. It clearly belongs to this type, but has 

 been much reduced by the violent usage to which the butt has 

 been subjected, breaking off large conchoidal and irregular pieces 

 until hardly more than the bevelled sides are left. The latter, 

 however, are very fine, long, quite smooth, well polished, and 

 unequally convex. The cutting edge is broad and symmetrical. 

 Measurements in this case are unnecessary. The rock is a dark 

 green chloritic quartzite showing faint lines of lamination. 



3. Deltoid, or subtriangular Type. This is perhaps one of the 

 less common forms of stone tomahawk, the specimens exhibited, 

 three in number, being certainly peculiar in shape. The first is 

 from Normanton (PL xxx., figs. 3 and 4), again communicated, 

 like so many of these fine implements, by Mr. C. W. De Vis, from 

 the Queensland Museum Collection. It is a remarkably short 

 and broad tomahawk, oval-deltoid in shape, originally a flattened 

 pebble of dark green diabase or hypersthene gabbro. The butt 

 has been chipped, but the remainder of the surface is quite smooth 

 and glazed. The broader end has been ground on both sides to a 

 cutting edge possessing a wide circular sweep, moderately sym- 

 metrical in its curvature. The measurements are : — Length, 

 3 Jin. ; breadth, 3Jin. ; thickness, If in. ; weight, 11 oz. 



Supposing this weapon to be hafted it would not, by any means, 

 be unlike some of the small single-handed battle axes used by the 

 knights of old. Of a similar type to the present is, I believe, the 

 tomahawk figured by Smyth from the Munara district,* composed 

 of a highly polished aphanite. It is much larger, however, than 

 our example, and weighed two pounds four and a-half ounces. It 

 is, of course, possible that this implement may appertain to the 

 next general group, which I have" termed "axes" in contradis- 

 tinction to " tomahawks," but its resemblance in shape to the 

 Normanton tomahawk has induced me to refer to it here. 



The second of these deltoid implements is from the Macquarie 

 River, by the Rev. J. Milne Curran. It is an obtuse sub-deltoid
