the natural crust of the stone in many cases needs no 

 dressing for prehension, and it would not comply with (^), 

 as it is not an edged tool, and would not therefore require 

 re-sharpening, but it would show special marks of bruising 

 from use. 



(15) Apart, however, from some few special cases as 

 instanced above, we take it that a rigorous compliance 

 with the conditions specified would establish the fact that 

 a given tool was the work of man, and not a natural pro- 

 duction. 



(16) As already stated, we hold that the Eolithic 

 tools were originated and developed by pre-palceoHthic 

 man, and in consequence the various industries prior to 

 Palaeolithic times may be designated as purely Eolithic. 



(17) The Palaeolithic and Neolithic periods which are 

 characterised by the presence of stone and bone imple- 

 ments intentionally shaped and fashioned for a definite 

 and specialised, even if unknown, purpose, include also the 

 Eolithic types, which were retained for general purposes. 



(18) There is evidence, however, at many places in 

 this country and on the continent, that in Neolithic times 

 isolated communities existed, which remained as the 

 Tasmanians did, entirely in the Eolithic culture stratum. 



(19) Any industry which comprises only the original 

 types of simple tools, without any admixture of inten- 

 tionally shaped or ground tools, may be termed purely 

 Eolithic. 



II. Eolithic Types. 



(20) In classifying the various forms of Eoliths, 

 following Rutot, we have departed from the usual 

 methods of classification according to shape, colour, 

 locality, name of donor, etc., in favour of a classification 

 based on the manner in which the tools were employed,
