Mr. William Phillips on the 
the chalk and blue marie near Folkstone, imbedded in a sandy clay 
of a reddish brown colour. In less than a furlong this kind of 
deposit is confined to the summit of the rising cliff, which consists 
beneath of sand lying in thin beds of different colours, rising con- 
formably,* or nearly so, with the rise of the cliff ; but the general 
tint of the mass is greenish. The probability that this sand may 
belong to the plastic clay formation occurred to me, but I dis- 
covered nothing beyond the general appearance of the sand to 
strengthen the suspicion. 
The junction of this sand with the chalk is not visible, being 
covered with loose sand and alluvial matter. The one however 
seems to abut against the other, as shewn in the accompanying 
sketch (PI. 1. Fig. 2). 
The chalk which first appears at the base of the cliff, after 
passing the sand, is without flints, and exhibits but few traces of 
organic remains ; it perfectly resembles that which rises at the foot 
of Shakspeare’s cliff near Dover in softness and in sandiness of 
aspect, especially just below its junction with a superincumbent 
stratum, consisting of thin beds of organic remains. This stratum 
resembles so closely that which lies in the same position on the 
west of Dover, that no difference in its aspect or composition is 
visible ; and these two beds are in each place separated by a bed 
of soft chalk marie, which, having fallen out by exposure, has left a 
perfectly defined crevice along the cliff. It is this stratum of 
organic remains which is occasionally observable from Dover, as a 
darkish line, even without a glass. 
Grey chalk soon after rises to view from beneath the chalk 
without flints or organic remains, and forms the dark line at the 
base of the cliff observed by S. Woods, Esq. from near Dover : it 
has all the characters of that which underlies a similar bed on the
