W. WHITAKER ON SOME BORINGS IN KENT. 31 



An examination of the cores showed, says Mr. Newton, that at a 

 depth of about 500 feet (30 feet from the top part) an irregular 

 nodular bed occurs, with many shells of Inoceramus (which seemed 

 to belong to J. Brongniarti and /. Ciivieri). He was unable to 

 identify the zone of Belemnites plenus, though many Belemnites were 

 said to have been found in the Chalk, but at what depth was not 

 known. 



Low down in the Chalk Marl the following characteristic fossils 

 were got : — Baculites baculoides, a fragment of a Hamite, and part of 

 a Pecten Beaveri. 



The Gault cores were fast disappearing, broken up by frost and 

 then overgrown, and no trace of fossils was to be seen. No clue 

 could be got to any horizons therefore ; but, from specimens sent to 

 the Geological Survey in 1880, the following list has been made, 

 and the fossils seem to have been chiefly found at depths of from 

 855 to 882 feet.

A small undeterminable Gasteropod was the only fossil found 

 after washing specimens of the sandy clay forming the bottom part 

 of the Lower Greensand, between the depths of 934 and 938 feet ; 

 whilst specimens from 941 and 942 feet yielded only fragments of 

 shells. There is therefore no fossil evidence as to the age of the beds 

 which have been classed as Lower Greensand, and it has been 

 suggested that some few feet of the top part may be sandy beds of 

 the Gault ; but, in the absence of evidence, the only safe plan is to 

 class the whole of these beds together. 



Unless the few phosphatized Ammonites have fallen in, from the 

 junction-bed with the Gault, they are, I think, in favour of the 

 above view, although the occurrence of derived fossils (as some of 

 these seemed to me to be) has not been noticed in the Lower 

 Greensand of this district. The specimens are much rolled. 



A specimen from the top part of the Oxford Clay yielded, on 

 washing, fragments of bivalve shells and a minute Gasteropod ; but 

 none of these were determinable. From a depth of 945 feet down- 

 wards fossils were found in aU the specimens. They are essen- 

 tially the same throughout, and all very small ; but they leave no 

 doubt as to the age of the beds. It is noteworthy that of the nine 

 species figured by G. Damon as characteristic of the Oxford Clay *,
