I should, perhaps, have noticed here the worked flints found so abundantly in some parts of the south of England, which have long attracted the attention of collectors, and have in some cases been referred to glacial or pre-glacial times. I believe, however, they are all really post-glacial, though in some cases belonging to the earliest portion of that period.[13] [13] Prestwich on 'Ightham Beds,' _Journ. Geol. Soc._, 1893; Dawkins, _Journ. Anthrop. Soc._, 1894. We may close the present chapter by presenting to the eye in a tabular form the series of events included in the pleistocene and modern periods of the great cenozoic time. LATER CENOZOIC, OR TERTIARY PERIOD (_In Ascending Order, or from the Older to the Newer_) Newer Pliocene.--A continental period of long duration, elevated land, much erosion, much volcanic action. Pleistocene.--Irregular elevation and depression of the land, ending in wide submergence with cold climate. Glaciers on all mountains near to coasts and ice-drift over submerged plains. Glacial period, with an inter-glacial mild period in the middle and great submergence of the continents toward the close. Anthropic.--_Palanthropic_, or post-glacial, in which the land emerges and attains a very wide extension, and is inhabited by a varied mammalian fauna. Man appears in Europe, Asia, and North Africa. Terminated by a recurrence of cold and great subsidence, deluging all the lower lands. _Neanthropic._--Area of continents smaller than in the previous period. Surviving races of men and species of animals repeople the world. Modern races of men and modern animals. CHAPTER IV THE PALANTHROPIC AGE[14] [14] Called by some 'Palæolithic,' from the use of implements like that figured on p. 41. We have now to inquire more particularly what we can learn as to the earliest men known to us, those who appeared in Western Asia and Europe at the close of the glacial period, when the cold had passed away and a genial climate had succeeded, and when the continents of the northern hemisphere had attained to their largest dimensions, were clothed with a rich vegetation and tenanted by an abundant mammalian fauna, including many large and important creatures now extinct.
