478 PROCEEDINGS OF THE GEOLOGICAL SOCIETY. [June 19. 



The results which I infer from our observations, though the area 

 visited was very limited, are not without some interest and novelty : 

 they are — 



1st. That the freshwater conditions of a portion of our Wealden 

 were to some extent contemporaneous with the Portland beds, or 

 belong to the oolitic period. 



2nd. That the ironsands and gravels of the counties of "Wilts and 

 Berkshire are of the age of the Neocomian formation of the conti- 

 nental geologists. 



3rd. That the Neocomian formation is unconformable with, and 

 separated from, the true cretaceous series by a wide interval of denu- 

 dation. 



4th. That the aspect of its fauna is partly oolitic. 



5th. That the identity of the materials of the gravel beds of the 

 Farringdon and Portland beds shows the condition of the area of 

 water, as to extent, depth, and direction of distribution, to have been 

 the same for both. 



6th. That the Farringdon beds and their equivalents (lower green- 

 sand) must therefore be considered as the remains of an independent 

 formation, of which the greater portion was removed by denudation 

 before the deposition of the Gault.
