stone throughout; in some places the 

 ironstone dies out and leaves the shale as 

 the sole representative of the stratum ; 

 in others the shale passes into iron, the 

 band becoming ferruginous in its entire 

 thickness. 



The strata {n, ^^, of the sectional sketch) 

 underlying the shale and ironstone are 

 conformable to them, and occur in the 

 same irregular undulating lines : they 

 are also continuous, and at present more 

 or less visible, through the entire section, 

 with the exception of the neighbourhood 

 of Lee Ness. They may be studied also 

 with advantage on the beach under East 

 Cliff, particularly on the east of Eagles- 

 bourne, where they occur in the following 

 descending order : — 



1st. A band of sandstone ; about 



4 feet thick. 

 2nd. Slate-coloured compact clay ; 



7 feet thick. 

 3rd. Light-coloured clay ; 4 feet 



thick. 

 4th. Dark clay ; thickness unknown. 



At Cliff End these beds have been so 

 far removed from their original position 

 (and, as it were, are so thrown over on 

 their sides), that the present surface of 

 the shore is formed of their edges, or by 

 a section transverse to the plane of stra- 

 tification. 



At a distance of nearly 2000 yards to 

 the east of the Lovers' Seat, several hun- 

 dred square yards of the upper surface 

 of the sandstone or superior member of 

 this subgroup are exposed, and form the 

 promontory or projection known as Lee 

 Ness Point, the preservation of which 

 may be attributed to the greater hardness 

 and durability, as well as the peculiar po- 

 sition, of the upper members of this sub- 

 group. On the east of Lee Ness these 

 strata increase considerably in thickness ; 

 the clays below the sandstone (which is 

 here about 9 feet thick) being intersected 

 by arenaceous deposits, and the band of 

 sandstone separated from the shale and 

 ironstone above by layers of clay, which 

 gradually diminish in thickness to the
