494. During this period, the Mediterranean basin was reduced 

 to some small patches of water, which appeared in the Savoy, 

 and in the region upon which the French Alps now stand. These 

 are marked upon the map by the number 25. 



495. Before the geology of Western Europe, in relation to this 

 age, was submitted to the elaborate analysis of M. D'Orbigny, 

 from which the details explained above have resulted, M. Elie 

 de Beaumont published a map of its geography during this 

 period, of which we give a reduction in fig. 190. 



It will be seen that, according to this, the Anglo-Parisian

basin was not inferred to be divided into two separate gulfs, as 

 above described, but an insular tract was supposed to be formed 

 around the country of Bray in France, and another around the 

 Wealden in England. 



The basin was assumed by M. Elie de Beaumont to extend 

 between Paris and the Lizard Point, Cambridge and Maestricht. 

 The Pyrenean basin is represented as limited between Bordeaux 

 and Dax. It is probable, however, that the more recent
