his old friend, it will be well to quote his conclusions zn 
evtenso.* 
“The great changes of land surface in this part of the 
European area were referred—firstly, to the movements 
accompanying the elevation of the Pyrenees, when the chalk 
became dry land, with its uplands, valleys, and estuaries; 
at that time the Wealden area formed an island in the 
Thanet-Sands sea. 
“Some rivers afterwards brought down the clays and 
sands which now constitute the ‘ Woolwich-and-Reading’ 
‘beds. With some submergence other Tertiary beds were 
formed, probably extending over a part of what is new the 
Wealden Area. 
“Secondly, this area with its stratified coatings was 
raised up (after the formation of the London Clay) by move- 
ments accompanying the elevation of the Alps, by the 
lateral pressure caused by the earth’s contraction. The other 
Tertiary beds (of Paris, Bracklesham, etc.) had helped to 
shallow the sea surrounding the island of the Weald, which 
was ultimately to be an elevated, elliptical, weather-worn, 
and sea-eaten dome of great height.

feet); also their successive denudations, and the original 
place of the Old Gravel (4), some of which was brought 
down by natural agencies to the Chalk Plateau (5) now 
existing.
