Mr. William Phillips on the 
rection parallel with the stratum ; but undulating grey veins pass 
along it, and here and there may be extricated from them small 
conical masses in every respect similar to those which have already 
been mentioned in page 27. 
Just beneath the thin bed of marie forming the line of stratifica- 
tion, two thin beds of separate flints are very visible, but not lying 
in the same manner as those belonging even to the thinnest beds in 
the chalk with numerous flints ; their largest surfaces are not parallel 
with the stratum ; but on the contrary, as they lie in every direc- 
tion, they do not form an even line in regard to each other ; and 
this is the general character of the few thin beds of flints occurring 
in this stratum, which do not continue for any considerable distance. 
Flints sometimes lie in the occasional thin beds of sponges which 
appear on the face of the cliff, and sometimes exhibit impressions 
of them on the surface. The flints interspersed in the chalk of this 
stratum are frequently cylindrical, and are sometimes in the form of 
the bulbous head of the alcyonium, or in shapes resembling vege- 
table stems : such flints I have observed. here and there of more than 
two feet in length and scarcely exceeding half an inch in diameter, 
but they were always cracked across in several places. 
The grey veins so numerous in the lower part of the superior 
stratum, are almost as frequent in this, but prevail most just above 
or below the thin beds of organic remains and of flints above- 
mentioned, and in the neighbourhood of those numerous and 
nearly parallel crevices which are so many indications of regular 
stratification. 
The ammonite has hitherto, I believe, been supposed to be first 
visible in the under chalk, or that without flints. A large one lies 
in the cliff about a mile eastward from Dover, nearly in a horizontal 
position, and just above a bed of flints which runs for some distance
