DECADE V.—VOL. IX.—NO. VII. 19 290 Professor T. G. Bonuey ^^ Ret: E. Hill— April. On approaching the site of the bluff along the shore fromCromer, we perceived tliat not only the arch but also headland ^had disappeared; the cliffs rising from a fairly even base to a heightof over 150 feet. On the steep face of one of them we noticed awliitish patch, in form a rather elongated oblong, with its base a veryfew yards above the beach, the colour of which suggested the presenceof chalk. Perhaps a coixple of hundred yards before reaching it wecame upon a well-laminated dark clay, rising from the beach andrunning obliquely along it to the base of the cliff. After passing itwe found the ordinary boulder-clay of the Contorted Drift group. >W Scalfi 0+lyards \ \U.\r\lFig. 1. Sketch-plan (by Eev. E.

Tbe face of the cliff on either side of it, for somelittle distance, consisted of a yellowish-grej clayey sand, which here,as is locally not infrequent, was less conspicuously bedded than inmany places. The light-coloured patch, which was about 16 yardsbroad at the base and 18 yards or more in greatest height (the cliff atits back recedes just enough to be out of sight when viewed from theshore •* at a distance of 30 or 40 yards), included on its eastern side ^ We believe
