[I. Correlation of the time divisions with human industries 443 



1. Correlation of the Penck and Bruckner time divisions with 



human industries 443 



2. Correlation of the Deperet and Mayet time divisions with 



human industries 450 



Correlation : Chellean industry = Second Interglacial Period 



= Terraces of 28-32 meters 450 



Correlation : Acheulean industry ■=■ Middle and upper por- 

 tions of terraces of 28-32 meters beginning with close of 

 Glaciation III (Riss) and ending with approach of Gla- 



ciation IV (Wiirm) 455 



Acheulean arrival in Belgium 457 



Correlation : Mousterian industry = Beginning at the end 

 of arid lower loess and extending through IV Glacial 

 Maximum (Wiirm of Penck, Monastirian of Deperet) = 



Terraces of 18-20 meters 461 



Correlation : Aurignacian industry = Recession of Glacia- 

 tion IV (Wiirm) continued into beginning of Postglacial 

 time — End of Monastirian stage of Deperet = Terraces 



18-20 meters 463 



Correlation : Solutrean industry contemporaneous with late 

 Aurignacian and early Magdalenian industries = Second 

 arid or "Middle Loess" Period = Achenschwankung and 

 Buhl of Penck 466 



3. Correlation of the De Geer geochronology with human indus- 



tries 467 



4. Theoretic correlation of Quaternary geology, archeology, and 



mammalian paleontology, according to our knowledge of 1921, 



by Osborn and Reeds 470
