Mr. William Phillips on the 
in the course of this range ; and with them are connected some beds 
consisting almost wholly of organic remains, that have not, I believe, 
been described as occurring in other places. The strata lie in the 
following order, and are collectively about 820 feet thick. 
1st. The chalk with numerous jlints ; it is about 350 feet thick, 
and may be thus divided ; 
I. With few organic remains, lying upon 
II. A bed consisting chiefly of organic remains ; in which 
numerous flints of peculiar forms are interspersed, and a 
few beds of flint run along it. This bed, I term, the chalk 
with interspersed jlints . 
2d. The Chalk with few jlints ; this stratum is about 130 feet 
thick. 
3d. The Chalk without finis is 140 feet thick, and consists of 
I. A stratum containing very numerous and thin beds of organic 
remains, 90 feet thick. 
II. A stratum about 50 feet thick, with few organic remains. 
4th. The Grey Chalk ; this is estimated to be not less than 200 feet 
in thickness. 
I propose to offer a few observations on the nature and stratifi- 
cation of these deposits, upon the flints of such as inclose them, on 
the stratification of the green sand of Folkstone, and on the blue 
marie overlying it in the neighbourhood of that place. 
The accompanying sketch (Plate 1.) exhibits the range of these 
cliffs, from the signal-house above Folkstone to Walmer Castle. It is 
essential to be noticed, that they do not run in the same direction 
throughout their whole length. From the signal-house above Folk- 
stone to the South Foreland, their general bearing is N.E. by E.; 
* from the latter place the cliff is somewhat curved to St. Margaret’s 
Bay; whence, to Walmer Castle, its direction is nearly due north.
