Another type included in this group are specimens 

 from which it is impossible to say whether they are 

 nuclei, or unfinished rejects. These specimens are fre- 

 quently of a large size, and to the casual observer they 

 would appear to have been worked all round on every 

 side. It is, however, obvious that these specimens cannot 

 be considered as implements, which it was intended to 

 work on both faces. In the first instance, their lumpy 

 form, the entire absence of any shape, proves that they 

 must be either nuclei or iinfinished rejects. I found one 

 of these specimens near Kempton, and the flakes tiiat had 

 been struck oflf were still lying around it, and could be 

 fitted into their places- We have here clearly a nucleus, 

 and its flakes, both being rejects. Other specimens equally 

 prove that numerous attempts had been made to produce 

 a smooth Pollical face, but either owing to the nature of 

 the rock or ill-directed blows, these attempts failed, and 

 the specimen was rejected. 



D. LAMELLIFORM IMPLEMENTS. 



This group is distinguished from the former chiefly 

 "by its smaller thickness, and that more specimens show 

 that a considerable amount of work has been spent, not 

 only in trimming the Indical face, but also bevelling tiie 

 edges. We might consider them as flakes of group Bb/2, 

 whose Indical face has been so much worked that original 

 crust has entirely disappeared. (1). 



I think this group includes all those which Sir John 

 Evans has termed "trimmed flakes." 



The lowest type are flakes with a good Pollical face, 

 whose Indical face has been wrought by one or a few more 

 large chips being struck off. The sharp edges were gene- 

 rally utilised without previous bevelling. Fig. 8 is a good 

 illustrative specimen of this type.

The next figure shows a lamelliform implement, whose 

 Indical face has been more elaborately worked. 



(1) Frequently enough small traces of the original crust still adhere to the 

 implement.
