Extract

The object of the following paper is to record some further observations on the distribution in North Wales of deposits of White Clays and Sands older than the Boulder-clay and its accompanying gravel drifts, similar to those in the neighbourhood of Llandudno, described in the Geological Magazine of May, 1865, and also to give a condensed summary of what records I have been able to collect of the occurrence of similar deposits in other parts of the kingdom.
