LOWER CHALK—KENTISH COAST.

by piecing on the beds seen at Baker’s Harbour west of Shakes¬ 
peare’s cliff to higher beds seen at the western entrance of the tunnel 
it appears to be divisible into three portions which in descending 
order are as follows : — 
ft. 
Yellowish-grey chalk, massively bedded ; seen for - - - 23 
Grey chalk with large patches or mottlings of yellowish-grey 
(top not seen) - - - - - - - - - 21 
Massive grey blocky chalk, with Rhynchonella Grasiana , 
Disco idea subuculus, etc. - - - - - - -16 
Mr. Rhodes obtained many fossils from the middle part, including 
Holaster subglobosus, Hol.trecensis, Gidaris Bowerbanki (spines), 
Pseudodiadema ornatum, Ps. Normanice and Pecten Beaveri. 
Bed 7 .—This bed was recognised by Mr. Whitaker and 
mentioned in his “ Geology of the London Basin ’’ (1872), p. 33. 
Writing of the “Grey Chalk ” as defined by Phillips, he says, “Near 
the top there is a more massive bed, about 8 feet thick, which at 
Hay Cliff has small hard projections, some being pyrites, some 
fossils, and others stony lumps.’’ By Mr. Hill’s measurement 7 feet 
is the thickness, but it may be a little over, and the material may 
be described as greyish-white chalk in thin beds containing hard, 
flattish lenticular lumps or knobs of hard stony chalk, which 
weather out prominently. Large Ammonites occur in this bed, 
one of which was taken to Jermyn Street and identified as Am. 
[. Acanth .] rotomagensis. 
Bed 8. -This is the subdivision called byW. Phillips, “chalk 
without flints and with few organic remains.’’ He describes it as 
forming the base of Shakespeare’s cliff rising from the beach at 
the eastern end of that cliff, and as traversed by trail verse or 
vertical joints which give this chalk “ an angular appearance, not 
common to any other parts of the cliff.’’ 
It is a soft whitish chalk, and, as Phillips remarked, it con¬ 
tains very few fossils ; Discoidea cylindrica and a few fragments of 
a Holaster , either trecensis or subglobosus , were the only fossils found 
by us, but Mr. Price mentions palates of Ptychodus polygyrus and 
P. decurrens as found towards the top of his Bed VI. Nodules of 
iron pyrites, some spherical and some cylindrical, are common, 
and are of a dark colour externally. Our estimate of 53 feet closely 
agrees with that of Phillips’, who gives “ about 50 feet ” as its 
thickness. 
Bed 9 (Bed VII. of Price).—This is the soft marl of W. Phillips 
dividing “ the whiter and softer chalk ” from the “ hard yellowish ” 
chalk above ; and it is the bed which Mr. Whitaker describes as 
about 6 feet thick and containing Belemnites. * Mr. Price’s account 
of it is not clear, because he describes it as “ yellowish, gritty, white 
chalk,” and in referring to Mr. Whitaker’s Memoir, he quotes the 
description of a very different bed at a lower horizon, that namely 
which separates the grey from the white chalk, i.e., our Bed 7.
