ESSAI D'uNE MoNOCRAPHIE 1)ES D^POT MARIN ET CONTINENTAUX DU 

 QlTATERNAIRE MoSfiEN, LE PLUS ANCIEN DE LA BeLGIQUE, par MiCHEL 



MouKLON (Extrait des annales de la Societe Geologique de Belgique), 

 Tome XXV., bis, p. 121, 1900. 



Director Moarlon in this essay describes an ancient surface deposit 

 of Belgium, with full details of the localities where it has been recog- 

 nized. 



Northern Belgium is covered with a marine deposit subjacent to the 

 "Campinien," which carries the remains of Elephas primigenius, 

 Rhinoceron tichorhinus, etc., with flint flakes and other remains of 

 human industry. M. Moarlon traces this marine deposit to central 

 and southern Belgium, where it is represented by terrestrial and fluvia- 

 tile deposits. In these, down to the very base, he finds flint chips and 

 implements of palajolithic type. This formation he terms the Conti- 

 nental Moseen, and considers it equal in age to the ancient gravels, 

 antedating the present river valleys, which Prestwich has described. 



Director Mourlon draws the following conclusion : " I think I may 

 assume from all that precedes, that, in the present state of our 

 knowledge, the presence of fliut flakes in the deposit referred to the 

 Landenian of the vicinity of Mons, as well as the mammiferons bone 

 beds in the Bruxillian sands of Ixelles, appear to authorize us to con- 

 sider these deposits as constituting a new geological horizon, whose 

 age remains to be determined, but which is anterior to the pebble 

 deposits with Elephas primifjeidus at the base of our Quaternary 

 Diluvium- -the Campinien. 



At the end of the memoir is a map of Belgium showing the area over 

 which the Marine Moseen is spread.

A New Physical Geography. ^-Probably in no other scientific 

 branch has there been such a change of method in the matter of pres- 

 entation as in the study of the topography and physiography of the 

 earth's crust. In the old days it was all included under geography 

 which it was in toto with the exception of a brief prefatory explanation 

 of planetary relations and the phenomena of changing seasons and 

 temperatures. Geography in the old days dealt with the rivers and 

 mountain ranges, the valleys and bodies of water, but chiefly with the 

 arbitrary divisions of the earth's surface made by man, the political 

 centres and commercial marts. All this has. been changed in recent 

 years. The natural has been separated from the artificial, and the 

 former has been given its right place in school curricula. An import-
