and must here content myself to give a general description of the Shepherd's Gutter and Brook Beds. The former, the equivalent to the Nummulina Bed at Stubbington, Bracklesham,
and White-Cliff Bay, is so called from a small stream at the foot of Bramble Hill Wood, about a mile due north of the King's Gairn Brook. The measurements are as follow :— (1) Gravel from one to five feet; (2) light-coloured clay, with
following interesting measurements:—(1) Beds of marl, containing Voluta geminata, discovered forty years ago, at Cutwalk Hill, by Sir Charles Lyell, and now re-discovered, and a small Marginella, seven feet. (2) Bed of bluish sandy clay, which becomes, when weathered, excessively brown. This bed, very rich in fossils, which are in a good state of preservation, is equivalent to what is now called the Middle Marine Bed, at Hordle and Brockenhurst, sixteen to nineteen feet. (3) Hordle Freshwater Beds, containing two species of Potanomya, and comminuted shells, fifteen feet. (4) Upper Bagshot Sands, measuring, as far as the workmen have gone, twenty feet, and below which lies the water at the top of the clay. The important point to be noticed is the extreme thinning out of the Hordle Freshwater Beds, which, from the depth of two hundred and fifty feet at Barton have here shrunk to fifteen. Mr. Prestwich has suggested that these beds, as they advance in a north-easterly direction, become more marine, which seems here to be confirmed.
