Chalk Cliffs near Dover .

it observable, that the angular masses are always the least. In fact, 
the aspect is what may be termed shattery, and it prevails in so great 
a degree in the three openings near the turn of the Dover road below 
the signal-house, and on the side of the conical hill, near to which 
the road to Canterbury passes, that the chalk there had, at first sight* 
the appearance of not being in situ. 
On comparing accounts of different parts of our great chalk 
deposit, it clearly appears that there is not every where a perfect 
uniformity in its strata. No such beds of organic remains as accom- 
pany the chalk with numerous flints and that without flints near 
Dover, have been described as oceuring in other places. The chalk 
marie underlying the chalk without flints in the Isle of Wight* is 
wanting near Dover ; for the grey chalk underlying it near that 
place differs from the chalk marie in its general colour, in not pul- 
verizing by exposure to air, or shivering by the action of frost ; nor 
does it contain nodules or beds of greater induration, except the thin 
beds of sandstone already mentioned : moreover, it contains nearly 
the same organic remains as are found in the chalk above it, while 
the fossils of the chalk marie in the Isle of Wight, differ from those 
found in the chalk in every instance but onef. The beds of sand- 
stone oceuring in the grey chalk of Dover, many however prove it 
to be analogous with the grey chalk of Cambridgeshire, although it 
is described by Professor Hailstone as being harder than common 
chalk, while the grey chalk of Dover is softer. If indeed they be 
analogous, the chalk without flints is wanting in Cambridgeshire,, 
for the flinty chalk there reposes on the grey chalk. J
