Chalk Cliffs near Dover . 
25 
The numerous knotty projections of this part of the cliff are 
much harder than chalk commonly is, and than that in which they 
are imbedded. These remains of organic bodies do not lie in thin 
or separate beds ; but form one large bed, occupying about one-third 
part of the whole height of the cliff beneath the castle, and in the 
centre of it. 
The beds of flint lying immediately above this bed of organic 
remains, are less frequent and much thinner than those which are 
nearer to the summit of the cliff, and some beds of flint are visible 
among the organic remains. Indeed there does not appear any 
decided line of separation between this bed and the superincumbent 
chalk with numerous flints, and hence their junction is left un- 
decided in the accompanying sketch of the cliff (Plate 1.) : we may 
consider this bed, though it contains comparatively very few beds of 
flint, as the lower part of the chalk with numerous flints. 
The whole bed has, from below, a greyish appearance ; and by 
this it may be traced by the eye for at least two miles, dipping 
gently in its course, which terminates at the foot of the cliff just at 
St. Margaret’s bay, four miles on the east of Dover. It may be 
seen along the cliff at the back of the town of Dover, and is visible 
west of it as forming the upper part of Shakspeare’s cliff, and 
terminating on the summit of the cliff about two miles beyond it. 
Its run is discoverable, not by the exterior roughness alone, but 
also by the presence, near the bottom of it, of two parallel and rather 
thick beds of flint, which are about four feet apart, and may be 
seen along the whole course of the bed, as I have described it. 
Between these beds of flint, lies a thin bed of soft marie, which, be- 
coming friable and crumbling away by exposure, leaves a crevice 
which accompanies the beds of flint, and which is visible for the
