G. Dowker — On the Chalk of Kent. 



locality) ; Sarr, Thanet ; Pegwell Bay, Thanet ; Eastry ; Word ; 

 Wingham ; and Canterbury. 



I offer the following list of fossils as open to some correction, and I 

 might add to the species could I determine the names of all the fossils. 



I leave others to draw their inferences from the Paleeonto- 

 logical evidence, but it is clear that the Margate Chalk may on 

 this be correlated with that of Norwich ; and I am of opinion 

 that on lithological evidence we may assume the Kentish Chalk to be 

 as high, if not higher,, than that of Norfolk. 



The section of Chalk from Folkestone to Foreness accompanying 

 this jDaper is an ideal section, the heights above the sea-level given 

 as accurately as I have been able to estimate them, and the names 

 of places on the section as approximately as I could place them with- 

 out pretending to absolute accuracy.
