Seite 386 - This might give to Palaeolithic man... no greater antiquity than perhaps about from 20,000 to 30,000 years ; while should he be restricted to the so-called post-glacial period, his antiquity need not go farther back than from 10,000 to 15,000 years, before the time of Neolithic Man1.
Seite 517 - Waterstones,' a bed of greenish-yellow sandstone 10 inches thick, with intercalated streaks of red and green marl, and a seam of pebbles at its base, and to the bottom inch or two of that stratum.
