1. On the Denudation of Soft Strata. 

 By the Rev. 0. Fisher, M.A., F.G.S. 



(Abstract.) 



The author first described the general features of the north-eastern 

 portion of Essex, which consists, in part, of table-lands of gravel, 

 with valleys cut into the subjacent London Clay and terminating 

 seaward in tidal rivers, and, in part, of a gently undulating surface 

 of London Clay, from which the gravel has been mostly swept clean 

 away, except in places where flat outlying tracts of gravel still 

 remain: these features extend also into the neighbouring county 

 of Suffolk. The tidal rivers are evidently nothing more than a con- 

 tinuation of the valleys beneath the sea-level ; and the same may be 

 said of irregularly shaped inlets of the sea, like that behind Walton- 

 on-the-Naze, which is a submerged valley in the part of the district 

 where the surface is composed of London Clay. 



The present configuration of such a district cannot be due, in the 

 author's opinion, to the action of such causes as we now see in 

 operation on the coast combined with a slow and continued elevation
