550 MESSRS. JUKES-BROWNE AND W. HILL ON THE LOWER PART 



Whitaker * as the probable representative of the Totternhoe Stone. 

 This hard grey chalk is underlain by exceedingly hard creamy- 

 white chalk, which passes rather abruptly into a softish, grey, clayey 

 marl. At the junction of these two the hard material was de- 

 cidedly yellower, and it passed into the bed below as layers or 

 lumps separated by the marl. The section obtained by digging and 

 boring is as follows (fig. 2) : —
