PROF. J. PRESTWICH ON THE RELATION OE THE 



It marks a period of slow submergence, succeeded by the 

 return at intervals of a very depauperized marine fauna. 



The Forest Bed itself is a distinct and local deposit, beneath the 

 Westleton Shingle ; but whether it forms an intermediate deposit 

 between the Shingle and the Chillesford Beds, or whether it is 

 synchronous with, and representative of, the Chillesford Clay, I take 

 to be a still unsettled problem.
