were identical with those from the surface layer. In the sandy 

 and gravelly zones lettered C, flakes are very rare, only two 

 being found by the committee. Next in order is the lower 

 gravel D, and as this bed was considered to require special ex* 

 amination, it was divided into four zones (lettered Di, D2, D3, 

 and D4, in descending order), which were consecutively ex- 

 amined, the flints from each zone being kept separate. It was 

 found that flakes occur sparingly all through this bed, from top 

 to bottom ; a few cores were also obtained, and one fine example 

 of a rude celt (at a depth of 1 1 feet from the surface). It was 

 noted that the flints were fresher and less oxidised than those 

 of the upper gravel, and the edges sharper. In the next bed, E, 

 which consists of black clayey gravel, and which could not be 

 so thoroughly examined on account of water coming in, one 

 fine flake was obtained (19 feet below surface) ; it was remarked 

 that it bore no trace of oxidation, and that its edges were as 

 sharp as if it had been just struck off. 



Underlying this bed came the Estuarine Clay and associated 

 strata, in which no flakes were discovered ; but it is worthy of 

 mention that in the lowest bed of gravel, at a depth of 28 feet 

 below the surface, several flint chips were obtained bearing a 

 considerable resemblance to flakes.
