IN the preceding chapters I have endeavoured to show that 

 the study of the successive phases of the glacial period 

 in Europe, and the enduring marks which they have left on 

 many of the solid rocks and on the character of the super 

 ficial drift, are of great assistance in enabling us to appreciate 

 the vast lapse of ages which are comprised in the post- 

 pliocene epoch. They enlarge at the same time our concep 

 tion of the antiquity, not only of the living species of animals 

 and plants, but of their present geographical distribution, 

 and throw light on the chronological relations of these spe 

 cies to the earliest date yet ascertained for the existence of 

 the human race. That date, it will be seen, is very remote if 

 compared to the times of history and tradition, yet very 

 modern if contrasted with the length of time during which 

 all the living testacea, and even many of the mammalia, have 

 inhabited the globe. 



In order to render my account of the phenomena of the
