THE ANTIQUITY OF MAN 201 



of Northern Europe and America off the face of 

 the globe. 



It will be necessary to say something about 

 the glacial periods and the genial intervals, but, 

 since this article is chiefly concerned with the 

 question of man, before this can be done it will 

 be desirable, first of all, to sketch as briefly as 

 possible the various races or successions of man- 

 kind during the Prehistoric Period. We shall 

 then be in a position to understand the views 

 put forward as to their relationship to the differ- 

 ent epochs of the Glacial Period. Two matters, 

 namely, the Trinil remains, the so-called Pithe- 

 canthropus Antiquus ; and the question of eoliths 

 having been already discussed at sufficient length 

 need not further be dealt with here. 



Passing from the possible eolithic period, we 

 find ourselves confronted with two sub-divisions 

 of the prehistoric age, Mesvinian and Strepyan, 

 accepted as definite epochs by Sollas, but included 

 as early Chellean, with the first generally accepted 

 epoch, by perhaps the majority of authorities. 

 Up to comparatively recent times it might have 

 been said that Chellean man was known only by 

 his implements, of which by far the most im- 

 portant and characteristic was the coup-de-poing, 

 or " boucher," to use Sollas' term, a kind of hand- 

 axe of stone not intended for insertion in or 

 attachment to a handle. But there are two ex- 

 ceedingly important fragments of human re- 

 mains which it seems may be at least tentatively 

 associated with this period. The first of these is 

 the so-called Heidelberg mandible, found under
