FACTS AND FANCIES, 



the present European races. The occupation 

 of Europe, and probably of Western Asia, by 

 these oldest tribes of men was closed by a 

 subsidence or submergence at the end of that 

 "second continental period," as it has been 

 called by Lyell,* in which they lived. When 

 the land was restored to its present condition, 

 they were replaced by the ancestors of the 

 present European races. 



It may be well here to tabulate that later por- 

 tion of the earth's geological history in which 

 man appeared, more especially as it is some- 

 times arranged in a manner not suited to con- 

 vey a correct impression of the actual succes- 

 sion. It will be seen by the general table given 

 in the last lecture that the latest of the Tertiary 

 ages is that known as the Pleistocene or Post- 

 Pliocene, and this, with the succeeding modern 

 period, may be best arranged as follows : 



I. Pleistocene, including — ' 



{a) Early Pleistocene, or First Continental Period. Land very 

 extensive, moderate climate. 



[b) Later Pleistocene, or Glacial (including Dawkins' " Mid- 

 Pleistocene "). In this there was a great prevalence of cold and 

 glacial conditions, and a great submergence of the northern land. 



II. Modern, or Period of Man and Modem Mammals, includ- 

 ing— 



[a) Post- Glacial, or Second Continental Period, in which thfc 



* The first continental period was that of the earlier f liocepe.
