Chapter 1733
[←1723]
Scientists now admit that Europe enjoyed in the Miocene times a warm, in the Pliocene or later Tertiary, a temperate climate. Littré’s contention as to the balmy spring of the Quaternary—to which deposits M. de Perthes’ discoveries of flint implements are traceable (since when the Somme has worn down its valley many scores of feet)—must be accepted with much reservation. The Somme-Valley relics are post-glacial, and possibly point to the immigration of savages during one of the more temperate periods intervening between minor ages of Ice.
