belief that the English Palaeolithic flint-implements of Chellean, 

 Acheulean, and early Mousterian periods were of Interglacial 

 age had been forced upon him by the results of his researches in 

 East Anglia. That they had commonly been referred to post- 

 Glacial times was, in his opinion, due to the fact that English 

 geologists had confined their attention to gravel-deposits made up 

 entirely of derived material, of which the implements formed a part. 

 These, however, as in the similar case of Jurassic material found 

 in post-Glacial gravels, must be referred to some pre-existing 

 •deposit or land-surface, and it was only the discovery of unabraded 

 specimens resting upon or beneath undisturbed Glacial accumula- 

 tions that was of any real value. He would like to call the 

 attention of the Fellows present to his published views on the 

 subject, 1 and to suggest that much important evidence might 

 be forthcoming if detailed excavations were made in the Cromer 

 Forest-Bed. He pointed out that there was no fixed agreement as 

 to the exact type of implement indicated by the term Chellean, 

 .and urged the need of a satisfactory nomenclature for British 

 Palaeolithic deposits. 



The Lecturer agreed with Mr. Whitaker in emphasizing the 

 Importance of measuring the height of river- terraces from the river 

 and not from the sea-level. In reply to Mr. Johnson, he stated 

 that he thought there was no difference of opinion as to the age 

 •of the Somme Valley : its excavation was completed down to the 

 first terrace at the close of the Chellean ; but he knew of no 

 Chellean floors in that valley. Hunters often camped by the side 

 of a river, and implements were frequently lost on its banks. In 

 reply to Mr. Hazzledine Warren, he was inclined to think that the 

 river-terrace was already in existence before it was covered by the 

 moraine associated with it ; but he had not seen sections that 

 could dispose of this question one way or the other. Subsequent 

 fan-deposits of outwashed gravel and other accidents would render 

 investigation difficult, and might confuse the issue. 



To other speakers he offered his apologies for his imperfect 

 hearing, which had prevented him from following closely their 

 remarks.
