CHAPTER XVII. 



POST-GLACIAL DISLOCATIONS AND FOLDINGS OF CRETACEOUS AND DRIFT 

 STRATA IN THE ISLAND OF MOEN, IN DENMARK. 



Geological Structure of the Island of Moen Great Disturbances of the 

 Chalk posterior in Date to the Glacial Drift, with recent Shells M. Pug- 

 gaard's Sections of the Cliffs of Moen Flexures and Faults common to the 

 Chalk and Glacial Drift Different Direction of the Lines of successive 

 Movement, Fracture, and Flexure Undisturbed Condition of the Eocks in 

 the adjoining Danish Islands Unequal Movements of Upheaval in Finmark 



Earthquake of New Zealand in 1855 Predominance in all Ages of 

 uniform Continental Movements over those by which the Eocks are 

 locally convulsed . . . <" * .;' . - ' PAGE 341 



CHAPTEE XVIII. 



THE GLACIAL PERIOD IN NORTH AMERICA. 



Post-glacial Strata containing Eemains of Mastodon Giganteus in North 

 America Scarcity of Marine Shells in Glacial Drift of Canada and the 

 United States Greater southern Extension of Ice- action in North America 

 than in Europe Trains of Erratic Blocks of vast Size in Berkshire, Massa 

 chusetts Description of their Linear Arrangement and Points of Departure 



Their Transportation referred to Floating and Coast Ice General 

 Remarks on the Causes of former Changes of Climate at successive geological 

 Epochs Supposed Effects of the Diversion of the Gulf Stream in a 

 Northerly instead of North-Easterly Direction Development of extreme 

 Cold on the opposite Sides of the Atlantic in the Glacial Period not strictly 

 simultaneous Number of Species of Plants and Animals common to Pre- 

 glacial and Post-glacial Times 351 



CHAPTEE XIX. 



RECAPITULATION OF GEOLOGICAL PROOFS OF MAN'S ANTIQUITY. 



Recapitulation of Eesults arrived at in the earlier Chapters Ages of Stone 

 and Bronze Danish Peat and Kitchen-Middens Swiss Lake-Dwellings 

 Local Changes in Vegetation and in the wild and domesticated Animals and 

 in Physical Geography coeval with the Age of Bronze and the later Stone 

 Period Estimates of the positive Date of some Deposits of the later Stone 

 Period Ancient Division of the Age of Stone of St. Acheul and Aurignac 



Migrations of Man in that Period from the Continent to England in Post- 

 Glacial Times Slow Rate of Progress in barbarous Ages Doctrine of the 

 superior Intelligence and Endowments of the original Stock of Mankind 

 considered Opinions of the Greeks and Eomans, and their Coincidence 

 with those of the modern Progressionist Early Egyptian Civilisation and 

 its Date in comparison with that .of the First and Second Stone Periods
