sand and clay which are so highly inclined near their point 

 of contact with the chalk. In the diagram it will be seen that 

 from the projecting point of chalk the cliff retires in a series 

 of ledges and small precipices in which inclined beds of drift, 

 2, d, are exposed for an aggregate thickness of several hun- 

 dred feet. At the top of the cliffj which I conjecture to be 

 about 400 feet above the sea, the beds of sand seemed to be 

 horizontal, but these it should be observed are not imme- 

 diately over the inclined beds. Respecting the tilted beds 

 which are in contact with the chalk, it will be sufficient to say 

 that they consist of gravel, sand, clay and loam like the stra- 

 tified drift before described, that the clays are occasionally 

 finely laminated, and that broken fragments of Norwich crag 

 shells are dispersed through some of the strata ; but there are 

 no signs here of the freshwater or lignite beds. 



The second or middle protuberance of chalk is near that 

 last described: its front along the shore measured in 1839, 

 65 yards. Its height was between 15 and 20 feet. 



The third and most considerable mass extends along the 

 beach for a distance of 106 yards, (see fig. 7.) and its position 

 deserves particular notice, for it forms like the southernmost 

 mass a projecting promontory about thirty yards beyond the 

 general line of cliff. On both sides of this promontory it is 

 seen that the beds of gravel, clay and sand which abut against
