EXPLANATION OF THE PLATES. 
''PLATE 1 . 
In illustration of Mr. W. Phillips’s paper on the Chalk Cliffs near Dover, &c. 
Fig. 1. Is a sketch of the Chalk Cliffs between Deal and Folkstone. It must 
however, be noticed that in this sketch, the height of the cliffs is too great 
in proportion to their length, the dip of the strata being somewhat less than 
one degree. If reduced to their actual proportionate height, it would 
scarcely exceed one-fourth that of the sketch. 
Fig. 2. Is a view of the Chalk Cliffs forming Cape Blanc Nez on the coast of 
France, opposite to Dover. It will be observed that the beds of Fig. 1 & 2 
seem to dip in opposite directions, but if the spectator be supposed to be on 
the sea between the two coasts, he will look nearly noith while viewing 
the Cliffs near Dover, but nearly south when viewing Cape Blanc Nez. 
The dip in both is towards the east. 
Fig. 3. Represents an Inoceramus from the Chalk with few flints near Dover; 
it is described at page 55, by Mr. Parkinson, who has named it Inoceramus 
Lamarckii. 
Figs. 4. & 5. Are Inocerami from the blue marie near Folkstone; they are 
described by Mr. Parkinson at page 59, as Inoceramus concentricus, and 
inoceramus sulcatus.
