core weighs 51b. lOoz , the total of the 41 flakes is 21b. 

 15oz. ; core and flakes weigh, therefore, 81b 9oz. m the ag- 

 gregate, but as the top portion is still missing, the weight 

 of the original boulder was probably not less than 101b. 



The spalls that were struck off this bo'ulder exceed 

 more than 41, and vary considerably in size and weight. 

 We can distinguish external and internal flakes, and the 

 last one that was struck off a typical internal flake of the 

 1st order weighs almost 4 ounces. All further work was 

 stopped after this flake had been struck off, and we must, 

 therefore, consider it as the desireu object- This view is 

 further borne out by the fact that many of the flakes pre- 

 viously struck off seem by the sharpness of their edges emi- 

 nently suitable as implements, yet they were disregarded. 



Unless we believe the very improbable theory that an 

 aborigine amused himself by striking off about half a hun- 

 dred of spalls from a parent block with no object at all, we 

 must take it that the object of all this hard work was the 

 production of a flake of either certain weight or shape, or of 

 both. So far no evidence has been found that the shape of 

 a flake was material, and we must, therefore, assume that it 

 was desired to produce a tero-watta of a certain weight, 

 and as weight is dependent on the size, we might also say 

 of a certain size. 



It may seem somewhat rash to generalise from one 

 specimen only, but the Kempton nucleus seems to- Throve 

 that whenever a pebble of suitable rock was broken, it was 

 with the view of obtaining a flake of a desired weight (and 

 size). All others were disregarded, no matter how suitable 

 they may appear to us. This view is borne out by the evi- 

 dence of the quarries. I have repeatedly pointed out that 

 it appears unintelligible that such a number of apparently 

 eminently suitable flakes were rejected, while others that 

 seem to us much less suitable were used- There is only one 

 explanation for this fact, viz., that the primary object was 

 to obtain a flake of a certain weight (or size). Sometimes a 

 larger, sometimes a smaller, flake may have been wanted, 

 but, however suitable the other flakes that fell off may have 

 been, they were disregarded. 



(B) THE TESTED REJECTS (pseudo-nuclei). 



As stated above, there is another group of pebbles and 

 boulders which has been subjected to a certain amount of
