1 {k) Septaria ; containing shells and occasionally Eostellaria 



ampla (68 paces), resting on a mass of Cardita planicosta 



and C. acuticosta. The lower part of the bed is green 



sand, crowded with sheUs, among whicli, immediately 



quently referred to in the text. It will be observed that, wherever a tract of 

 PleLitocene forest is approached, the bordering Eocene deposit is " weathered ; " 

 but if the Pleistocene be subaqueous at that spot, the bordering Eocene retains 

 its original colour. Weathering is caused by tlie atmospheric air which the rain 

 carries down with it as it percolates the soil. Another interesting phenomenon 

 here is the furrowed condition of the surface of the Eocene beds, caused by the 

 coursing of drifting gravel over them. The furrows are filled with large flints 

 and Ixjuldcrs from the older rocks, in many places undisturbed, but sometimes 

 washed out by the present waves and redeposited in the furrows along with 

 shingle from the present beach. 



* Fossil shells, in a beautiful state of preservation, are frequently washed up 

 by the sea in the neighbourhood of tlio Cerithium-bed. They probably are 

 derived from lenticular patches of shells on the horizon of No. 11, and correspond 

 with the fossil-bed of Hill Head, near Stubbington. 



f Concretions containing this Nummulite are often washed up by the sea. 

 They are probably derived from No. 4. The Numniulite-bcd No. 6 is green in 

 Brm-kle^ham Bay. but yellow at the Park, where it has suffered Pleistocene 

 weathering.
