CORRELATION OF THE TIME DIVISIONS 455 



of error in the appreciation of altitudes (Summary by Deperet, 192-1.1, 

 page 126). 



Correlation: Acheulean Industry = Middle and Upper Portions of Ter- 

 races of 28-32 Meters, beginning with close of Glaciation III 

 (Riss) and ending with approach of Glaciation IV (Wiirm) 



This correlation accords with the work of Commont above cited and 

 with Mayet (Mayet, 1921.2). 



Like the Chellean, the Acheulean industry (compare Osborn, 1915.2) 

 presents two or three phases, as follows : 



Late Acheulean. — Marked evolution Cool Acheulean. — Associated with 

 of flaked flints — for example, Levallois the flora of a cool temperate climate 

 blades, acme of the coups de poing (tuf de La Celle-sous-Horet) ; also 

 industry ; perfected use of the flint arid, older or "lower loess" deposits 

 cores ; improved flake industry, in- all over northern Europe. Disappear- 

 cluding perfected Levallois blades, ance of the hippopotamus and south-

 entrances of the grottoes during cold

 Chellean. Several varieties of coups Chellean times. Survival of hippo-

Virchow (1920.1). 



Saint Acheul, Abbeville, Menchecourt, Montieres, in the valley of the 

 Somme, all exhibit Acheulean layers overlying the Chellean and some- 

 times divisible, through the flint evolution, into early-warm- Acheulean 

 and late-cool- Acheulean, as, for example, on the high terrace of Saint 

 Acheul (figure 8). 



La Celle-sous-Moret. — This Acheulean horizon is particularly interest- 

 ing. A terrace of 30 meters was built up by gravels representing about 

 one-half of its height — that is, elevated 15 meters above the existing
