Hitherto, exposures of the junction of the Bunter formation with the Keuper, in the Nottingham district, have shown the brown sandstones and red marls of the “Waterstones,” with a band of dolomitic conglomerate at the base, resting directly on an eroded surface of the Bunter Pebble Beds. Recently, howeve, between these formations there have been observed to intervene certain deposits that agree both in mineral composition and in physical characters with the white sandstones and conglomerates, known as the “Basement Beds,” that form so important a feature in the Keuper of the West Midlands.

page 533 note 2 We are indebted to C. F. Gripper, Esq., contractor for the works, and to M. 0. Tarbotton, Esq., F.G.S., Engineer to the Nottingham Corporation, for the lower portion of the-third section, which was arrived at by means of a shaft sunk for the purpose at Hough Hill Wood; but owing to the water-level of the Trent valley being reached, the sinking had to be abandoned without proving the Bunter.
In consequence of the great length of two of the sections referred to, their publication with the present paper has been abandoned by its authors.
