782 THE PLIOCENE DEPOSITS OP HOLLAND. [Nov. 1 896. 



Mr. H. B. Woodward referred to the excellent geological map of 

 Norfolk made by Mr. Harmer before the official Geological Survey 

 was commenced, and remarked that the Chillesford Clay had been 

 one of the chief sources of dispute. While working in the Norwich 

 area he had found no persistent divisions in the group which 

 included the Muvio-marine Crag, the Chillesford shell-bed, the 

 Chillesford Clay, and the Bure Valley Beds, and he had grouped 

 them under the general term Norwich Crag Series. He was there- 

 fore glad that Mr. Harmer now agreed that the beds belonged to 

 one formation ; and if it were desirable to use a term that should 

 correspond with the other group-names used by the Author, he 

 would suggest that the old term ' Icenian' be used for this Norwich 

 Crag Series. He was disposed to agree with Mr. Harmer's general 

 conclusions with regard to the Chillesford Clay, and thought that 

 now there were no serious differences of opinion between them ; the 

 Author in fact had done much to harmonize a subject which before 

 was full of discord. 



Mr. W. J". Lewis Abbott said that he had long since come to the 

 conclusion that we must know considerably more about Tertiary 

 Holland and Belgium before we can know the correct history of the 

 Weald. His closer studies of the latter had suggested hypothetical 

 conditions in these countries, which this valuable paper would show 

 to actually exist. The Lenham Beds might be shown to extend a little 

 south of the position indicated on the map, and very much farther 

 west. About Lenham the casts of fossils in the ironstone are not rare, 

 but they quickly decrease as we travel westward. We note, however, 

 the incoming of flint-pebbles in a soft white condition. By the help 

 of these ironstones and the gradually altering nature of the sands we 

 can trace the Lenham Beds into Surrey. It was the southerly 

 elevation and north-easterly depression that subsequently raised the 

 Lenham sea-bed to hillsides, and it was the rivers which flowed 

 down these in later Crag times that deposited the Plateau-gravels 

 in which are found the first evidences of artificially-worked flints. 



The Author replied, thanking the Fellows for the reception 

 accorded to his paper.
