Yol. 68.] DREDaED from: the dogger bank. 327 



These discoveries seem to dispose of the idea that the Dogger - 

 Bank is in any way connected with a submerged escarpment of the 

 Mesozoic rocks. 



Mr. A. S. Kennaed congratulated the Author on his work, and on 

 the importance of the fresh evidence which he had collected. In the 

 speaker's opinion the deposits are of late Pleistocene age, and may 

 well be correlated with the buried channel of the Thames. The 

 occurrence of these soft strata and of the well-known buried river- 

 channels beneath the North Sea seem to the speaker to show that the 

 subsidence had been very rapid ; for these clays and peats, if they 

 had been exposed between tide-marks, would have been quickly 

 destroyed. 



Mr. S. H. Warren- remarked upon the variety presented by the 

 deposits which underlay the salt-marshes of the east coast of England. 

 In some cases these are of the Early Bronze Age ; in others they 

 are Pleistocene, and contain remains of Eleplias iwimigenius or 

 E. antiquKs, and U^iio littoralis. In one case the speaker had found 

 that a freshwater deposit with U. littoralis had been redistributed, 

 during the Pleistocene Period, under marine conditions. Similar 

 conditions might be expected to obtain on the Dogger Bank, 

 and this would make the unravelling of such hidden deposits a 

 matter of great difficulty. Careful records, such as those presented 

 by the Author, were of great value. 



Mr. H. Whitehead stated that, since the publication of a paper 

 by Mr. Goodchild and himself, they had received a specimen of 

 * moorlog ' from lat. 55° 10' IS", and long. 4° 20' E., which was 

 similar in character to the specimen exhibited by the Author. It 

 contained shells (chiefly Cardium), several of ^hich had the valves 

 united ; the matrix was a blackish mud which yielded many 

 seeds, identified by Mr. Clement Reid as those of Ruppia rostelJata. 

 Other plant-remains were present, some of which were in a state of 

 fine division.
