notched or chipped, the larger fitted to break bones 

 or other hard substances. The second consisted chiefly 

 of scrapers of varied types square, crescent or beak- 

 shaped, or double. The plateau implements of the 

 third group were more rare, and closely resembled 

 forms common in the valley such as those of 

 Abbeville and St Acheul. Although Sir John Evans 

 could not agree in this classification, and considered 

 many of the rude types only natural forms, the differ- 

 ence of opinion between the two friends never made 

 any difference in the brotherly footing on which, 

 during so many years, they stood to each other, and 

 to which they both held fast to the end. 



It may here be mentioned that Dr H. P. Blackmore, 

 F.G.S., has obtained a number of rude "Eolithic" im- 

 plements, from the plateau gravel of Alderbury Hill, 

 near Salisbury, and his testimony (given in the sequel) 

 in favour of their use by man is of great value. 1 

 Many examples may be seen in the famous Blackmore 

 Museum at Salisbury. 



From the series of plateau flints described in 

 Prestwich's paper, read before the Anthropological 

 Institute, we give a plate illustrating specimens from 

 each of the three above-mentioned groups. Although 

 isolated types of these rude flint implements often fail 

 to carry conviction, it is otherwise when a series with 

 identical chippings and markings are grouped together : 

 then the design and guiding hand of man to shape them 

 are evident. In no case has this been so clearly shown 

 as in the interesting paper recently published by M. A. 

 Thieullen, 2 in which numerous specimens of each type
