mediate period. 1 This view is strengthened by the 

 parallel case offered by the deposits in the valley of the 

 Wily, near Salisbury. 



1 Flint implements have been obtained from many other beds of gravel 

 in and about London, "at Shackle well, Lower Clapton, and in various other 

 localities in Kent, Surrey, and Hertfordshire. In some cases, as in those 

 of Canterbury, to which Mr. W. G. Smith has directed my attention, they 

 have been rolled in the bed of the stream before they were deposited, and 

 afterwards the bed of gravel in which they lay has been worked over again 

 by the stream and re-deposited, each change being marked by new frac- 

 tures and abrasions. A similar series of changes has taken place in the 

 lowest deposits in Kent's Hole, described in the next chapter.
