substantiated, and this they have hitherto been unable 

 to do. 



The Demonstration. 



In submitting our case for the existence of EoHths as 

 the work of man, we relied upon the presentation of series 

 of actual specimens, as it is only by seeing and handling 

 the pieces themselves that their real signification can be 

 estimated. 



The specimens exhibited may be divided into four 

 series. The first, which was experimental, showed the 

 characteristic traces of the various kinds of work for which 

 the tools had been used, together with the results of re- 

 sharpening on push planes and scrapers. 



The second series consisted of Eoliths which were 

 unrolled, and in which the essential characteristics had 

 not been sensibly obliterated or masked. 



The third series consisted of specimens from the 

 various Eolith-bearing formations, and showed the chrono- 

 logical sequence of the industries, the extent of their 

 distribution, and the persistence of type. 



The fourth series consisted of accepted Palaeolithic 

 and Neolithic forms, shewing on their edges secondary 

 working- similar to that on T^oliths.
