V. Remarks on the Fossils collected by Mr . Phillips near Dover and 
Folk stone .* 
,By JAMES Px\RKINSON, Esq. 
MEMBER OF THE GEOLOGICAL SOCIETY. 
[Read January 16 and February 20, 1818.] 
My object in the following remarks is to give a catalogue of the 
fossils collected by Mr. Phillips, and to offer at the same time such 
desultory observations as the fossils themselves may suggest. As the 
search for Organic remains was confined to the cliff, the following 
list must not be considered as a general catalogue of the numerous 
fossils which these strata are known to contain. 
* I take this opportunity of correcting some opinions which I formerly advanced in my 
paper on the strata in the neighbourhood of London, published in the first volume of the 
Transactions of the Geological Society. By observing similar pebbles congregated in par- 
ticular spots, and differing from those of other situations, as the pebbles-pf Woolwich, of 
the Middlesex gravel, of the Hertfordshire puddingstone, &c., I had been led to conclude, 
that they might have been formed at the bottom of former oceans, on the very spots, perhaps, 
in which they are found ; and that their figure might have depended more on chemical than 
mechanical action. But instructed by the paper of Count de Bournon on this subject, + I 
now entertain no doubt of the gravel of Middlesex having been derived from the flints of the 
upper chalk, and of their having acquired their present forms by attrition. 
Whilst speaking of the casts of some of the echini, I stated my doubts of their having 
belonged to the chalk; but this, I confess, was in consequence of my not being then 
aware of the various species of fossil echini which the chalk contains. I also concurred 
in the conjecture, that the calcareous spar of the echinite contained no flint ; but I have 
since ascertained that a considerable portion of silex sometimes permeates the calcareous 
spar.
