stone farther west than Framfield ; nor, perhaps, 
sliould we expect to find it but in the eastern part 
of the county, when we consider the low situation 
in the series which it occupies, and the direction 
of the line of elevation which broke up the strata 
of the south-east of England. 
In the deep valleys near Maresfield, Uckfield, 
and Buxted, beds of shale, with the cycla.s parm^ 
are found ; and the wells sunk through the sand- 
stone strata on the south of Uckfield, in some 
instances, reach the same deposits. At Streale, 
near Buxted, shale with similar organic remains 
has been collected.* 
In the parish of Maresfield, adjoining the new 
road to Tunbridge Wells, a sub-crystalline lime- 
stone, containing cyclas media, and pawn, has been 
dug up in the wells belonging to the cottages. 
Near West Hothly, in the valley of rocks already 
mentioned, and in others of the deep glens, bivalve 
limestone and sandstone occur, but their relation 
to the other members of the formation has not been 
ascertained. 
In Surrey, we find traces of the calciferous grit, 
* The argillo-calcareous strata of Sandown Bay, in the Isle of 
Wight f, are evidently identical with those above described. “Near 
the termination of the cliffs, towanls the middle of the bay, are several 
thin strata of a stone composed wholly of bivalve shells, in a calcareous 
matrix, much resembling the Purbeck stone, but the shells are larger. 
These strata are from one inch to three inches in thickness, and sepa- 
rated from each other by beds of shale and fibrous carbonate of lime ; 
they have the same inclination as the strata lying above them. These 
strata are the lowest in the island.’’^
