Fig. 2. Section near the coast between Poole Harbour and Christchurch, and following the line of strike of the New-Forest tableland to Southampton Water at Cadland. The continuation of this section on the east of Southampton Water is in the direction of the rise of the surface, and, with figs. 6 and 7, shows the slope of the tableland towards Southampton Water.

Fig. 3. Section from the coast half a mile east of Highcliff to Winckton Post, and continued from a point on the plain 1 mile to the east, to Burley Beacon, where a short branch diverges to Picked Post. The main section again divides at Bratley Plain, the western line crosses two bottoms to Leadenhall and intersects the northern escarpment of the New-Forest tableland, half a mile west of Bramshaw Telegraph. The eastern line traverses Ocknell Plain and Blackbush Plain, and cuts the escarpment 1 mile west of Bramshaw Church. This and the two following sections are in the direction of the rise of the New-Forest tableland.

Fig. 4. Section along two lines from Barton cliff, and from Hordwell cliff to Wilverley, and thence through low ground to the tableland near Stoney Cross.

Fig. 5. Section from the Solent, 2 miles east of Lymington, across Boldre Heath to the escarpment at Ladycross Lodge, and on to Matley Heath. This section shows the prolongation of the tableland down nearly to the sea-level along the Solent, and also the occurrence of detached gravel- topped hills beyond the escarpment.

Fig. 6. Section through Southampton along the Winchester road to Chandler's Ford, with a branch over Chilworth common to the escarpment near the "Tower of the Winds," the highest point of the tableland on the east of Southampton Water.

Fig. 7. Section from the coast between Brunage and Hill Head, and

Fig. 8. Section from 11/2 mile east of Hill Head northwards, show the relation of the gravel from which flint implements have been obtained with the gravel on the higher level of Titchfield Common.

Fig. 9. Section through Hayling Island northwards to a gravel-covered surface half a mile west of Bourne Common.

Fig. 10. Section through St. George's Down and Stapler's Heath to Osborne and Norris, showing the coincidence of the gravel-capped hills in the Isle of Wight, with a slope northwards corresponding to the slope southwards on the mainland.

Fig. 11. Map showing the area of the river-basins within which the gravel-covered tablelands are situated.

Fig. 12. Section of the gravel and brick-earth deposits exhibited in the cliff atForeland in the Isle of Wight.

Fig. 13. Comparative sections of the Brading and Freshwater valleys where they traverse the chalk.

Fig. 14. Contorted gravel and brick-earth in a pit near the railway at Anglesea, about 17 feet above the mean sea-level.

Fig. 15. Gravel in a pit near the "Tower of the Winds," Chilworth, 300 feet above the mean sea-level, where disturbance of the gravel appears to have arisen from the wasting of the beds beneath. The occurrence of white gravel, separated from the red by a black carbonaceous band, is also here seen.

Discussion.

The President referred to the raised beach at Brighton, which he had traced thence as far as Chichester. He inquired what evidence there was of the marine origin and contemporaneity of the beds identified with this beach by Mr. Codrington.

Mr. Whitaker noticed the occurrence of gravels similar to those
