to the south of west; then to become horizontal; and beyond St. Leo- 

 nard's, to rise a little from the sea^ — the same beds recurring- there in a re- 

 versed order. The Section, Plate X. b_, fig. 2, which is on a much larger 

 scale than Plate X. a. No. b, represents the cliffs here referred to, and 

 will illustrate the structure above described. 



(81.) The top of the great stratum of white and nearly pure sand, which 

 forms the cliff under the castle at Hastings, comes down to the shore at the 

 White Rock, and disappears under the sea on the west of it. A stratum which 

 has many of the same characters, and seems to be a continuation of that of 

 Hastings, rises at the bottom of the cliff, about 350 paces west of the 

 church at St. Leonard's ; all the beds in the intermediate space being con- 

 sequently higher in the series. There is still some obscurity as to their rela- 

 tions, from the effects of disturbance ; and some points are concealed : but the 

 following list gives an approach to the order of their succession, descending, — 

 with an estimate of the relative thickness of the groups, and the places in 

 which they are found.
