and by an extensive range of rocks similar in their composition to the 
Milliolite limestone of Paris, running to the east and west some miles 
into the sea; and on the shore by a coarse, soft, yellowish limestone 
often passing into sand, like the calcaire grossier of the Paris basin : 
at Bracklesham the Eocene deposits consist of a loose greenish sand, 
of calcaire grossier, and of a very great extent of London clay. 
These beds are often intersected by superficial muddy deposits and 
extensively overlaid by the Post-Pliocene formation: this is well-seen 
between Bognor and Selsey at low-water. The remains of mammife- 
rous animals are discovered in the muddy deposits, some being refer- 
able to extinct species, and others to existing species not now found in 
this part of the kingdom ; with these are associated marine shells of 
existing species, but many of them not known as such on the Sussex 
coast. A still newer deposit may be observed to the east of Bognor at 
very low tides, in which are the remains of large trees ; also to the west 
of Selsey, the trunks and roots of trees, hazel-nuts, &c. may be seen 
at low-water. These trees are not fossilized: they were probably 
destroyed by the encroachment of the sea at no very remote period.
