such as that of the Stoke Newington ' floor '. But it exactly 

 filled the place of a precursor of that industry. 



In reply to Mr. Johnson, he agreed that the climate ©f the 

 Arctic Bed was not an extreme Arctic one. It was always difficult 

 to draw sharp boundaries, hut he thought that all British deposits 

 yielding contemporary Elephant and Rhinoceros should he classed 

 as Pleistocene. He was a little puzzled by the Admiralty section ; 

 and would like to re-examine it in the light of the comparative 

 evidence now available. 



He thought it extremely probable that the clay in the flood- 

 plain gravel referred to by Dr. Sherlock represented the same 

 Arctic Bed ; but it would, of course, need examination. 



In reply to Mr. Larnplugh's question, he had not found any 

 direct evidence of the relation of the Clacton bed to the Glacial 

 deposits ; but the higher-terrace gravels with Chellean implements 

 contained erratics probably derived from the Boiilder Clay, while 

 the Clacton bed occupied a tributary channel which Avas trenched 

 through the plain of that higher terrace. 



With reference to the question raised by Prof. BosAvell, the 

 mammalia of the Clacton bed were very different from those of 

 the Forest-Bed; in the Author's opinion, Elej>lias meridionalis, 

 Hh/'noceros etruscus, and their associates, which characterize the 

 Forest-Bed, were definitely pre-Chellean.
