FOSSILS OF BOGNOR. 123 
of Bognor: it is also a remarkable fact, and shows the great extent of this por- 
tion of the Eocene formation, that Sir R. I. Murchison procured at Antipofka 
in Russia many fossils identical with those of Bognor.

* This refers to the district west of London only: eastward there are further subdivisions under the London clay. 
+ As in no part of this district there is a complete vertical sequence of the whole of the series, the several deposits overlapping 
one another from the lowest in the north to the highest in the south, the thickness of the strata varies most materially. A rough 
approximation of that of each deposit at its point of average development is all that can be given.
