part it is 60°, S., curving gradually towards high-water mark. At b the raised beach of flint-shingle, with masses of slightly rolled chalk, is seen reposing on it, dipping to the sea at about 6°, and above 8 or 10 ft. above the present high-water mark.

There are alternations of beds of very large flints beach-rolled, and layers of chalk debris, many pieces with the corners slightly rounded, varying from 6 in. to 2 feet in length. The fall of cliff at the spot represented in fig. 10 enables the geologist to measure the angle of deposition of the gravel and Combe rock north and south, and also to observe the face east and west. The dips at several points have been marked in the sketch. The raised beach dips south at from 6° to 8°, and the covering bed also south at 2°. We thus meet near the sea with the condition of the basement bed of gravel (b, fig. 10) and of the covering bed of gravel being deposited nearly horizontally, while
