Eocene formations may be said to recommence, and continue in a 
greater or less degree to Bognor. At the Barrack-lane end may be 
procured some good fossils, the Pyrula Smithii: the Panopea corrugata 
and Cultellus affins occur in the clay, but being delicate shells they 
are difficult to get perfect ; wood perforated by Teredines is likewise 
found. 
The Barn and Bognor rocks unite opposite Aldwick ; among them 
the cement-stone is found in great quantities, and occasionally beauti- 
ful specimens of the Nautilus are discovered by breaking the nodules ; 
some of the stones run into calcareous divisions, which circumstance 
has given them the name of ‘ Septaria.’ 
The sea is gaining on the shore, but at Aldwick a most excellent 
barrier was made by the late Sir Thomas Brooke Pechell, Bart., who 
placed large rocks opposite his house, in such a position as effectually 
to stop its encroachment.
