and ligliter ones, but boulders of that weight were ap- 

 parently the most serviceable. 



4. These boulders were used witnout any previous 

 treatment ; in fact, they ma,y be considered as true 

 '"eolithes." 



5. The compressed diabase pebble of oval shape, show- 

 ing various marks of blows along the edge, and a central 

 rough indentation on either one or two sides, cannot be con- 

 sidered as hammer-stones, whatever else their use or mean- 

 ing may have been. 



3. WERE ANVIL-STONES USED IN THE MANU- 

 FACTURE OF THE TERO-WATTA? 



iDr. Rutot, in his important paper, "Un Grave 

 Probleme" (1) thinks that he can distinguish anvil-stones 

 among the collection of specimens I sent him, but I am 

 afraid tliat, as fai* as the specimen so designated is con- 

 cerned, I cannot agree with him. I have not found a single 

 flake which I could declare as an anvil-stone, and it will, 

 therefore, be useful to discuss the question whether anvil- 

 stones were ever used at some length. 



The accounts of eye-witnesses are silent on this point. 

 Scott does not state that the "flint" which was chipped with 

 another rested on another stone, viz-, an anvil. In fact, 

 his statement almost seems to imply that the flint which 

 was chipped, was held by one hand, while the other wielded 

 the hammer. We are, therefore, obliged to study the tero- 

 watta in order to ascertain whether they bear traces of hav- 

 ing rested on an anvil-stone or not. It is pretty certain 

 that if a piece of hornstone rests on a hard support, while 

 it is hammered at. those portions of its surface that have 

 been in contact with the hard support, must become some- 

 what dulled. Now, as we know that the tero-watta were 

 wrought by blows that were directed from the Pollicai face 

 towards the Indical face, a flake must have rested on its 

 Indical face while the process of trimming it was performed, 

 if an anvil-stone was used. The traces of having rested on 

 a hard support should, therefore, be found on the Indical 

 face, but the result of such an examination is absolutely 

 negative. Among the thousands of specimens I examined, 

 there is not one whose Indical face shows marks of having 

 rested on a hard support. All edges are exceedingly sharp ,
