WE owe to Mr. Lamplugh a description of the lowest beds of the Gault and their junction with the Lower Greensand, as seen in sand-pits on the south side of Leighton Buzzard. Mr. Lamplugh proved the presence of the fauna of the mammillatus zone and found that the fossils preserved in the gritty phosphatic nodules of the lowest bed above the false-bedded sands include Douvilleiceras mammillatum (Schloth.) and the characteristic Desmoceras usually associated with it.

IT is common knowledge to all geologists interested in the Lower Eocenes of the southern part of the London Basin that, in the Oldhaven (Blackheath) Pebble Beds, pebbles of a brown quartzite are often to be found on searching amongst the rounded flints of which these beds are so largely composed. When geological parties visit sections exposing the pebble-beds of the Lower London Tertiaries, the search for these quartzites usually constitutes one of the items of the field-work to be done. A considerable number of these pebbles must, by this time, have been collected but, although their occurrence has given rise to a good deal of discussion and speculation, nobody appears, so far, to have undertaken a systematic examination of their characters and petrological affinities. The view has been propounded that the study of these pebbles would throw light on the question of the source of the material composing the Lower London Tertiary beds.

THE country round Bournemouth consists of a wedge-shaped plateau, lying between the River Stour and the sea, and ranging roughly from 100 to 200 feet above sea-level. Of the numerous valleys which intersect it, those that join the Stour present as a rule no special features, but most of those running down to the sea are of exceptional character and are known as chines—a term which does not admit of very accurate definition, but is generally applied only to valleys of more than usual steepness.

IN the Geological Magazine for February, 1919, J. W. Jackson and W. E. Alkins described the occurrence of a quartzose conglomerate at Caldon Low, Staffordshire. In August one of us (F. B.) pointed out some previous references to this outcrop. The curious and ambiguous reply by Messrs. Jackson and Alkins
