CHAPTER XIV. 



CRETACEOUS SERIES. 



WHEN the continent described in last chapter had en- 

 dured for a long period of time, submergence of the 

 area began to take place, accompanied by the deposition

 England is as follows, the oldest beds being placed at 

 the bottom :

Chloritic marl, Chalk marl, and Chalk without flints.

(Gault. 



T ( Lower Greenland. 



Br \Atherfield Clay. 



I may here mention that in parts of the Continent 

 of Europe, there are certain marine formations inter- 

 mediate in position and date between the Oolitic and 

 Cretaceous rocks, which are known as the Neocomian 

 beds, so called from Neocomium, the ancient name of 

 Neuchatel, in Switzerland, where they are well de- 

 veloped. The assumption that the Hastings Sands and 

 Weald Clay are the fresh-water equivalents in time of 

 the lower and middle parts of these continental beds, is 

 undoubtedly correct, the Lower Grreensand of English 

 geologists being the British representative of the Upper 

 Neocomian strata. 



Mr. Judd has shown that at the south end of Filey
