 Line of tabular flint. 



Softish white chalk, with more or 

 less defined rocky layers, com- 

 posed of yellowish chalk in 

 lumps or nodules, contained in 

 a softer matrix. 



J Hard, compact, yellowish rock, 

 with layers of nodules, passing 

 into softer chalk with rocky 

 layers. 



Chalk, with layers of hard crystal- 

 line lumps in a softer matrix, 

 passing upward into softer 

 chalk, still limipy, but the layers 

 less defined. Scattered flints 

 most abundant at the base.

The measurements from which this diagram is drawn up were taken at various 

 places between Dover and St. Margaret's Bay. There is no accessible place where 

 the whole can be mea«5ured. My impression was that the portion of the Chalk 

 represented by the zones H. planus and M. breviporus became thinner to the 

 westward. The measure of this portion was taken near the South Foreland.
