A conglomerate in the Keuper. —Whilst a drain was being cut in Argyle Street, joining Upper and Lower Eastvilles, one of the upper beds exposed consisted of a rather fine conglomerate, made up largely of rolled quartz pebbles of small size, compacted with rounded quartz sand and intermixed with coloured fragments (generally very small flakes) of softer shale or clays. I did not measure the thickness very carefully, but I should think that it did not exceed six inches, and as the drain is now filled up, the means of more accurate measurement are lost. The distance from the nearest denuded edge of the Coal-measures is as nearly as possible half a mile.
