Abstract
It has always been difficult to account for the feet that, while Moraine Drifts occur at such low levels in the Lake District, Marine Drifts are found at such high elevations in the surrounding district. Mr. Mackintosh's new facts throw some light on this phenomena, but do not entirely explain it, owing to his having given, in my opinion, far too little importance to the second Glaciation experienced by the Lake District after its emergence from the Glacial Sea.
