248 EXCURSION TO ALDRINGTON, BRIGHTON, AND ROTTINGDEAN. The drive next crossed the northern tongue of the coal­ field as far as Scout House Reservoir, and from this point for some distance, the rising ground on the north of the road is occupied by Pebble Beds, exposed in many quarries, while to the south the brick-clays belonging to the Coal Measures, lying unconformably below, were being worked in numerous large excavations (see section). The first branch of the Western Boundary Fault was crossed north-east of Cannock, and the rest of the journey to this town was over Pebble Beds. At Cannock the party was most hospitably entertained at tea by Mr. C. A. Loxton, LL.B., of Shoal Hill House. A somewhat hurried drive to Stafford took the party near the huge excavations in the Pebble Beds of Cannock Chase, the pumping station of the South Staffordshire Waterworks Company, and past Huntington Colliery, where a sinking through the Pebble Beds has been successful in finding coal.

CHAPMAN, A.L.S., HENRY EDMONDS, B.Sc., AND C. DAVIES SHERBORN, F.Z.S. E."cu?s;on Secretary: A. C. YOUNG, F.C.S. (Repo?t by C. D. SHERBORN.) MR. FREDERICK CHAPMAN having kindly consented to explain the Aldrington section (see PROCEEDINGS, p. 259), a small party left London by the early morning train, and had the opportunity, therefore, of comparing the Raised Beach and Elephant Bed at this end of Brighton with that originally described by Mantell to the east of Brighton. Meeting the main body in the afternoon, the Directors led the way to the shore, where Mr. Chapman explained the Pleistocene section, which at this point is : Soil, etc. El ephant Bed 50 to 60 ft. Pleistocene Old sea-beach S to 8 ft. { Sand ... 3 to 4 ft. Chalk NOVEMBER, 1899.] EXCURSION TO CUXTON AND BURHAM. 249 The" Elephant Bed" rests on the Chalk, which is more or less horizontal in the section, and so continues to Rottingdean. The Chalk belongs, according to Barrois, to the "Assise a Belemnitelles," which, he says, forms part of the "Zone a Marsupites." The characteristic fossils given in "Terrain cretace superieur," are, among others: Micraster cor-anguinum, Ofjaster (Cardiaster) corculum, Rhynchonella plicatilis, Belemnites merceyi, Inoceramus lingua, TerebratuHna striata, crinoids, cidarids, sponges, etc. Large Ammonites (A. leptojJhyllus) are very common in the cliff and on the shore, and a magnificent specimen from this locality has lately been exhibited in the British Museum (Natural History) Marsupites also occur, but on the outward journey the party were unable to find specimens, though some were secured on the return journey, from the shore, in the position pointed out by the Directors. The liberality also of the landlord of the "White Horse," Rottingdean, enabled several members to secure more or less perfect specimens. REFERENCES. Geological Survey Map. Sheets 5 and g.

EXCURSION TO CUXTON AND BURHAM. SATURDAY, JULY 1ST, 1899. Director: G. E. DIBLEY, F.G.S. Excursion Secretary: A. E. SALTER, B.Se I F.G.S. (Report by THE D,XOCTOR.) The members arrived at Cuxton at 11. I 5 a.m., and visited a pit a quarter of a mile south of the station, by permission of Messrs. Weekes & Trechmann. The Director remarked that on their journey from town they had passed over the highest zones of the Chalk in the London area, at Gravesend and Farningham Road. At Strood, they had seen Upper Chalk of a decidedly low - zonal character, the predominant fossil being Micraster coranguinum, with Echinoconus conicus, and in the two and a half miles from Strood to Cuxton successively lower zones formed the outcrop, so that it could be distinctly seen that the beds have a somewhat north-easterly dip. At Cuxton, the whole of the Chalk (over 200 ft.) was certainly below the M. coranguinum zone. Flints occur in the upper half of the section. The typical fossils are the Holaster planus, Terebratulina NOVEMBER, 1899.1.
