called Westleton Beds inland with those of South wold ? If so, 

 whence did he derive the small white quartz-pebbles which occur so 

 abundantly in those beds ? and if from the west, as he (the speaker) 

 understood the Author to say, how did the latter account for the 

 increase of the material as it got farther from the source of 

 supply ? 



Dr. G. J". Hinde was desirous of knowing whether the Author 

 had been able to discover the rocks from which the white quartzites 

 had been derived originally. He had been much surprised to hear 

 the formation of these beds seriously attributed to cataclysmal action. 



The Rev. H. H. Winwood, after some preliminary remarks 

 respecting the ' pluvial ' theory, formerly adduced in connexion with 

 the deposition of the drift, said that the source of the white quartz 

 had still to be traced. After hearing Prof. Prestwich's paper on the 

 "Westleton drift, he had found these characteristic pebbles about the 

 size of marbles, mixed up with lydian-stones, but no liver-coloured 

 quartz, on the Oolitic plateau (600 feet O.D.) on the south side of 

 Bath, immediately below the turf. 



The Author replied.
