THE CRUST OF THE EARTH. 



In cases where the organic remains are of a mixed character, 

 containing shells and other fossils, some analogous to existing 

 marine and other species, it may be inferred that such deposits 

 were made at the embouchures of rivers. 



By such inductions it has been ascertained that extensive tracts 

 of the surface of the globe, which are now dry land and raised to 

 elevations considerably ab'ove the level of the sea, must, at various 

 former epochs, have been submerged in the waters of the ocean. 

 A great part of France, including the country around Paris, 

 Normandy, Artois, Picardy, Franche-Comte, Burgundy, the 

 Cevennes, Dauphiny, and Provence, present examples of this.
