 General Remarks : — The sequence of deposits in the Croydon- 

 bore compared with that as illustrated in the Kent Town-bore 

 and immediate vicinity* reveals several disparities, when it is 

 remembered that a distance of only about four miles separate 

 the two areas. 



The disparities between them are : — In the Croydon-bore, 320 

 feet of Marine Pliocene, absence of typical Miocene, a thousand 

 feet of sandy beds with a paucity of Eocene marine fossils. In 

 the Kent Town section, no marine Pliocene, a typical develop
