The clay was excavated only to a depth of a few feet, thus preventing a great number of fossils being obtained. Those found, however, are sufficient for comparison with the zones of fossils found in larger sections, and thus may afford evidence of the amount of denudation to which the clay had been subjected at this spot before the deposition of the gravel. By far the most abundant fossil found in the London Clay was the _Pentacrinus sub-basaltiformis_, which was obtained in the rounded angular, as well as the perfectly cylindrical form. The following Mollusca were also obtained:--_Nautilus regalis, Pyrula Smithii, Fusus bifasciatus, Voluta Wetherellii, Pleurotoma teretrium, Natica labellata, Dentalium_, sp., _Leda amygdaloides, Nucula Bowerbankii, Cryptodon angulatus, C. Goodallis_, and _Syndosyma splendens. Teredo_ borings, _Serpula_, and teeth of _Lamma_ complete the list of organic remains. Septaria were abundant in the clay, many of which contained drift-wood, bored by the _Teredo_, one contained a _Nautilus regalis_ as a nucleus, and several exhibited the usual crystallizations of calcite, heavy spar, and iron pyrites. Selenite, however, was very scarce in the clay, being found only in small crystals, and these by no means numerous." In Nine Elms Lane resided Mr. Sellar, a respectable tradesman who kept a tea and cheesemonger's establishment, and who for five years discharged his parochial duties as an overseer. Greatly deploring the irreligious condition of the spiritually-benighted poor of the neighbourhood, he had erected at his own expense, a hall at the back of his premises in Everet Street, to be used for religious and secular educational purposes. Subsequently the hall was rented by the Wesleyan Methodists, and was used by them as a preaching station, Mr. Farmer acting as steward and superintendent of the Sunday school which he commenced there. When the Sunday school was opened in 1871, not more than 20 per cent. of the children who presented themselves for admission could read, and their knowledge of the sacred contents of the Holy Scriptures was _nil_. However, though the task was difficult, for seven years Mr. John Farmer, assisted by his small staff of Christian teachers:-- Plodded hard, and labour'd well As many in Nine Elms can tell. The hall is now engaged by the Metropolitan Tabernacle Evangelization Society. A Sunday school is still held in the place and evangelistic services conducted there every Lord's day evening.
