During the past eighteen years I have made certain observations on the cliff formation on the east of Brighton and on the sections successively brought into view by repeated falls of the cliff. The chief item to be noted from them is, that as the cliff wears back, the base-platform of chalk grows in height, that is, the old surface of the chalk dips towards the south. Also, that the layer of sand which Prestwich found above the chalk grew thinner and thinner, until it has now completely disappeared. At the same time the raised beach has grown in thickness from 1½ feet to 12 feet.
