lamplugh: buried cliff at SEWERBT." 
The total height of the present cliff at this place is about 
75 feet, but the buried chalk clift' has a height of only about 35 feet, 
the remaining 40 feet consisting of the overlying glacial beds. These 
beds are not clearly exposed, but seem to be as in the preceding 
complete section (Fig. 2) , wherein are shown the beds from top to 
bottom of the cliff. 
The beds lying above ^the old cliff need not be more particularly 
described in this report, but I shall have occasion to refer to them 
again in considering the age of the underlying deposits.'" 
A. The Old Sea-beach. 
In our excavation we always found, at the bottom, resting on a 
floor of solid undisturbed chalk and abutting against the base of the 
old cliff, a sea-beach of rolled blocks and pebbles of chalk with a 
little sand, having a thickness of from 3 to 5 feet. Where it 
lay lowest the bottom of this bed was just below the present high water 
mark, so that its upper layers were generally slightly above the level 
of the highest tides, but only so slightly that a stormy sea might 
yet overwhelm it. I think, however, that a slight elevation of the 
land or withdrawal of the sea is indicated, for the waves seem, in old 
times as now, to have reached to a higher level than the shingle, 
the cliff being sea-worn for two or three feet above the beach. 
In one place we uncovered a short shallow cave, a little over 
a foot in diameter and three or four feet in length, Avhich 
the waves had hollowed out in the face of the cliff. Among the 
shingle wer3 many rolled bones both of mammals and of fish, these 
being most plentiful close to the cliff-foot, whither, being lighter 
than the stones, they had evidently been flung by the breakers of 
a rough coast. A few marine shells were found in the sandy layers 
(see list below), and many of the chalk blocks were perforated by 
Pholas, Saxicava^ or Ciloua, but the shells had in all cases decayed 
out of the boring. 
Though the chalk of the adjoining cliff contains no flint, nor 
do the cliffs anywhere on the south side of the headland, there was a
