ResumoThe author commenced with some remarks on the general geological structure and picturesque features of the Isle of Wight, and then proceeded to direct special attention to some extensive ledges of low rocks visible from a considerable distance, and occurring seaward of Brook Point, a low promontory near and to the east of Compton Bay. The face of the cliff is here formed by the bassetting edges of the Wealden clays and sands, which alternate with occasional layers of argillaceous shelly limestone, rolled blocks of which are strewed along the beach. This limestone is formed of the shells of Paludina, Cyclas and other Wealden species, and is in every respect identical with the Petworth marble and Ashburnham beds of Sussex. The cliff at Brook Point is between thirty and forty feet high, and is capped by an alluvial bed of loam, sand and gravel. It is composed of beds of laminated clay and shale, with sands and sandstones of a bluish and reddish-gray colour, and these are interspersed with layers and isolated masses of lignite and lumps of iron pyrites. East of the Point a chine or chasm occurs, from the summit of which a stream gushes out and dashes down the face of the cliff to the sea-shore. This stream rises from beneath the sand beds islands, and flows through the alluvial gravel to the summit of the cliff. The auhtor then proceeded to qoute a graphic description of this spot, written nearly thirty-five years ago by Mr. Webster,
