distance of the Chalk, which suggests that a large portion of the 

 sarsens come from the Bagshot Beds. He had seen in the Hamp- 

 shire Basin sarsens with large masses of Bagshot Sand enclosed 

 in gravels. As to the gravels near Earnham, there was no intrinsic 

 evidence as to what they were, and he did not regard the Survey 

 classification in this matter as final. He would certainly not class 

 any of them as Bagshot. The expression ' plateau-gravel ' merely 

 implies that the deposit occurs at a high level, hut nothing further. 

 The materials of which these gravels are composed seem to come 

 more from the south than from any other direction. When flint- 

 implements are found in gravels, he would be inclined to call 

 these ' river-gravels.' 



Mr. R. S. Heeeies admitted the occurrence of sarsen-stones in 

 the Woolwich and Beading Beds, but did not think that there was 

 any well-authenticated instance of a sarsen-stone being found 

 entirely in the Bagshot Beds in the Bagshot district. In this 

 district the sarsens often occur on the top of the Bagshot Beds, or 

 partly embedded in them, but always where there is or has been 

 overlyiijg gravel, and the speaker thought that they belonged to the 

 gravel and not to the Bagshot Beds. 



Mr. A. E. Saltee had noticed sarsens near the mouth of the 

 Thames at Sharnell Street and Cobham, the Medway Valley near 

 Aylesford, St. George's Hill near Weybridge, and embedded in the 

 gravels at Lee-on-the-Solent, the position of which in every case 

 could be explained by the hypothesis advanced by the Author. 

 He was particularly struck by the remarks on ' redeposited Bagshot,' 

 and thought it extremely probable that the sands at Netley and 

 Headley Heaths on the North Downs were of this character. At 

 the former place the presence of a sarsen quite close to one of the 

 sections, at an altitude of over 600 feet above Ordnance datum, and 

 in all probability derived from the superincumbent gravel, lends 

 support to this idea. 



Mr. W. H. Shetjbsole said that he would mention two facts, of 

 small importance by themselves, which might be worth consideration 

 in connexion with other information. One was that he had often 

 seen fine-grained 'sarsen-stones' in situ at the base of the brick- 

 earth, resting on Chalk, in East Kent; and the other fact was 

 that, about 20 years ago, he found a large quantity of irregular 

 fragments of igneous rocks, differing greatly in size, embedded in 

 the upper part of the Lower Bagshot Sand at Mill Hill, Sheppey. 

 They were examined by competent petrologists, and pronounced to 

 be an assemblage which in all probability had been transported 

 from Scandinavia. His own opinion at the time was, and still is, 

 that ice had been the transporting agent. 



Mr. 0. A. Sheubsole had noticed contortions and irregularities in 

 the gravel of this district, but did not off'er an opinion as to the 

 cause which has produced them. He had also obtained from it 

 flints of the kind claimed to be imj^lements of an early type.
