CHAPTER XI. 



AGE OF HUMAN FOSSILS OF LE PUY IN CENTRAL FEANCE AND OF NATCHEZ 

 ON THE MISSISSIPPI, DISCUSSED. 



Question as to the Authenticity of the Fossil Man of Denise, near Le Puy-en- 

 Velay, considered — Antiquity of the Human Race imiilied by that Fossil — 

 Successive Periods of volcanic Action in Central France — With what 

 Changes in the Mammalian Fauna they correspond — The Elephas Meridio- 

 nalis anterior in Time to the implement-bearing Gravel of St. Acheul — 

 Authenticity of the Human Fossil of Natchez on the Mississippi, discussed — 

 The Natchez Deposit, containing Bones of Mastodon and Megalonyx, pro- 

 bably not older than the Flint Implements of St. Acheul Page 19-4 



CHAPTER XII. 



ANTIQUITY OF MAN RELATIVELY TO THE GLACIAL PERIOD AND TO THE 

 EXISTING FAUNA AND FLORA. 



Chronological Relation of the Glacial Period, and the earliest known Signs of 

 Man's Appearance in Europe — Series of Tertiary Deposits in Norfolk and 

 SuflFolk immediately antecedent to the Glacial Period — Gradual Refrigeration 

 of Climate proved by the Marine Shells of successive Groups— Marine 

 Newer Pliocene Shells of northern Character, near Woodbridge — Section of 

 the Norfolk Cliffs — Norwich Crag — Forest Bed and fluvio-marine Strata — 

 Fossil Plants and Mammalia of the same — Overlying Boulder Clay and 

 contorted Drift — Newer fresh-water Formation of Mundesley compared to 

 that of Hoxne — Great Oscillations of Level implied by the Series of Strata 

 in the Norfolk Cliffs — Earliest known Date of Man long subsequent to the 

 existing Favmaand Flora 206 



CHAPTER XIII. 



CHRONOLOGICAL RELATIONS OF THE GLACIAL PERIOD AND THE EARLIEST 

 SIGNS OF man's APPEARANCE IN EUROPE. 



Chronological Relations of the Close of the Glacial Period and the earliest 

 geological Signs of the Appearance of Man — Effects of Glaciers and Icebergs 

 in polishing and scoring Rocks — Scandinavia once encrusted with Ice like 

 Greenland — Outward Movement of Continental Ice in Greenland — Mild 

 Climate of Greenland in the Miocene Period — Erratics of recent Period in 

 Sweden — Glacial State of Sweden in the Post-Pliocene Period — Scotland 

 formerly encrusted with Ice — Its subsequent Submergence and Re-elevation — 

 Latest Changes produced by Glaciers in Scotland — Remains of the Mammoth 

 and Reindeer in Scotch Boulder Clay — Parallel Roads of Glen Roy formed 

 in Glacier Lakes — Comparatively modern Date of these Shelves 229
