 been made to show that man existed before 

 or during the Glacial Age, but this is very 

 unlikely, and, as I have elsewhere argued, the 

 evidence adduced to prove so great antiquity 

 of man, whether in America or Europe, has 

 altogether broken down.* 



At the close of the Glacial period the conti- 

 nents re-emerged and became more extensive 

 than at present. Survivors of the Pliocene 

 species, as well as other species not previously 

 known, spread themselves over this new land. 

 It would appear that it was in this " Post- 

 Glacial " period that man made his appear-

 the older cave and gravel deposits of Europe, 

 and which are referred to those palaeolithic or

 history in Europe and the arrival therein of
