well at the Rectory, the strata differ in a great degree: no marl is 
here observed, or any remains of the stratum or beach without shells 
as at Worthing. The result was fifteen feet of mould and gravel, 
most likely of the same age as the marl; and then a stratum of sand 
of seven or eight feet, containing recent marine shells,—Littorina rudis 
and L. Neretoides, Purpura Lapillus, &c. This is also the remains of a 
former beach, but older than the one described at Lancing, Worthing, 
and along the coast. 
At Sompting, more to the east, a little marl was mixed with the 
gravel for ten or twelve feet ; then came the sand with the same recent 
shells for six or seven feet as at Broadwater, under which the true 
chalk was penetrated and very good water procured. 
The beds containing gravel with and without marl, and the lower 
sand with shells, are evidently a continuation of those strata so well 
described by Dr. Mantell as forming the site of the eastern part of 
Brighton, and named by him the Elephant-bed. This bed may be 
traced westward from Brighton to Shoreham, forming a range of low 
cliffs: on the north side of Shoreham Harbour, and a little to the west 
of Copperas Gap, they can be advantageously examined, the geolo- 
gical position being well-marked. The bed of sand containing the 
shells still found on the coast, Littorina Neretoides, Mytilus edulis, 
Purpura Lapillus, &c., is seen im situ, lymg under the chalk marl and 
gravel ; also many specimens of much older formations : rolled portions 
of granite and porphyry are mixed up with the shells and sand, 
similar to what may be observed on the shore at the present day. 
Under the remains of this old beach the true chalk formation is found, 
as at the Elephant-bed beyond Brighton and at Sompting. 
We may therefore safely state, that m the neighbourhood of Wor- 
thing the tertiary beds from the Newer Pliocene are entirely absent. 
The most elevated point of these modern beds must be from eighty
