VI. Conclusion. 
I. Inrropuction. 
In two previous communications* I have laid before this Society the 
result of detailed studies of the fine cliff-section of Filey Bay in 
Yorkshire, and of the range of hills forming the western flank of 
the Lincolnshire Wolds. In each of these memoirs I have especially 
dwelt on the presence and relations of certain beds, which are proved 
by their fossil contents to belong to the great formation known by 
the names of Véocomien in France and Switzerland, of Hi/sin North 
Germany, and of Biancone in Italy. In pursuing this subject 
on the present occasion I propose,—first, to describe the inland 
development of these beds in Yorkshire; secondly, to furnish some 
additional particulars concerning the Lincolnshire beds; thirdly, 
to give a brief résumé of the whole of the facts known regarding the 
nature and relations of the Neocomian strata of the north of England ; 
and, lastly, to state the results of a personal examination and com- 
parison of these beds with their equivalents in North-western 
Germany. 
It. Neocomi1an STRATA OF THE VALE OF PICKERING. 
On the completion of my study of the succession of strata ex- 
posed in the cliffs of Filey Bay, it became an object of much in- 
terest to me to examine and map, as far as possible, the inland 
development of the same beds (Neocomian, Portlandian, and Kim- 
meridge), with a view to the confirmation or correction of the con- 
clusions I had then arrived at concerning their nature and relations. 
Unfortunately the whole district between the Wolds and moors of 
Yorkshire is so thickly covered with drift and alluvium as to render 
the examination of the underlying deposits a task of great difficulty. 
The Vale of Pickering was first excavated during preglacial times, 
in the soft Neocomian and Upper Oolitic clays which intervene be- 
tween the harder rocks of the Upper Cretaceous and the Lower
