 EDITORIAL NOTES. 



TpHIS month our Editorial notes are shorter than usual, owing 

 -L to j)ressure of other matter on our space, especially somewhat 

 lengthy corresj^ondence. which has to some extent upset the original 

 programme and caused one or two pajDers to be unavoidably held 

 over. Furthermore, the incidence of the Easter holidays has 

 made it difficult to keep up with current events in the geological 

 world. 



In the long list of recipients of various grades of the Order of the 

 British Empire we are glad to notice the names of some geologists, 

 though few in number. They are as follows : Mrs. Shakespear, 

 Dame B.E. ; Dr. F. H. Hatch, O.B.E. ; Mr. J. Allen Howe, O.B.E. ; 

 Miss G. L. Elles, M.B.E. ; Mr. H. T. Burls, M.B.E. We are by no 

 means sure whether the first item on this list is correctly expressed ; 

 if not, we offer apologies. 



At the annual meeting of the Prehistoric Society of East Anglia, 

 held at the rooms of the Geological Society on March 23, Professor 

 J. E. Marr delivered his Presidential Address, which dealt mainly 

 with the relationship of the deposits containing human relics to 

 the Glacial period. He considered that as the result of Mr. Eeid 

 Moir's discoveries the existence of Pliocene man in Britain has been 

 proved. After noting the possible existence of glacial conditions 

 in this country in late Pliocene times, he devoted the main portions 

 of the address to the Pleistocene period. He regards the evidence as 

 favouring the occurrence of a glaciation (the Cromer Drift glaciation) 

 at the beginning of the Pleistocene period, followed by genial con- 

 ditions during Chellean and Acheulean times. After this followed 

 the glaciation which caused the formation of the Chalky Boulder- 

 clay, which coincided generally with Lower Mousterian times. 

 A slight rise of temperature occurred during Upper Mousterian, 

 Aurignacian. and Solutrean times, though not necessarily sufficient 

 to cause the ice to disappear from more northerly parts of our Island, 

 and during the Magdalenian ])eriod the ice re-advanced southward 

 to some extent. If the period from Lower Mousterian to Magdalenian
