generic one qualifying it with a second term to denote 

 the chronological position of any given industry.* 



(8) An Eolithic tool may be defined as one formed 

 from a fragment of hard stone generally of siliceous 

 material, which from its shape has been selected .as 

 suitable for the purpose in view, and which, when neces- 

 sary, has been adapted for use by trimming. Such 

 fragments may be purely natural, or may be obtained by 

 shattering one stone against another, or by deliberate 

 flaking. 



(9) It is in connection with such trimmed fragments 

 that utilisation by man can be first asserted. 



(10) A Palaeolithic or Neolithic tool, on the other 

 hand, may be defined as one which has been intentionally 

 fashioned and shaped to a specialised form. 



(11) With Eoliths, therefore, we have the configuration 

 of the tools almost entirely natural, the fragments selected 

 having certain definite characteristics, and with Palseoliths 

 and Neoliths the configuration is almost entirely artificial, 

 and follows definite models. 



(12) It is evident, therefore, that in judging whether 

 Eoliths are or are not the work of man, the accepted 

 criteria applied to Paleoliths and unground Neoliths, viz. : 

 the bulb, cone, and conchoid of percussion, will not hold, 

 as in the majority of cases the fragments from which the 

 Eoliths were made were fractured naturally. 



(13) It becomes necessary, therefore, to set up other 

 criteria for Eoliths before we can assert definitely that 

 they are the work of man, and we would submit that the 

 following conditions with which an Eolithic implement 

 should comply are efficient criteria : — 



*It is proposed that this term shall be understood as meaning in a 

 primary sense the form of the stone implements, with the purposes for which 

 they were used in successive periods ; and in a secondary sense the state of 

 culture which is indicated by the.se implements.
