In a former paper I referred very briefly to the succession of glacial deposits in Switzerland. It was stated that no interglacial beds like those of Scotland and America occur in the Swiss grundmoräne. But, as every geologist is aware, Professor Heer and others have shown that the lignite-beds of the Cantons of Zurich and St. Gall are really of interglacial age, since they not only rest upon but are covered by glacial deposits. There can be but one opinion as to the position in the series occupied by these lignite-beds; they are clearly intermediate in date between the accumulation of the old grundmoräne and the deposition of that “moraine rubbish” which marked the new advance of the glaciers. ‘This being the case, they cannot represent the beds that occur in the “till” of Scotland, but must belong to a later stage. If this correlation be correct, it seems to me that the Swiss beds will serve partly to fill up a great blank in our record, and help us to realize the condition of our country in the long ages that elapsed between the disappearance of the great confluent glaciers and the subsequent period of submergence, which gave rise to the “kames” and “esker-drift.” This will appear probable, as I hope to show, after we have taken a glance at the glacial deposits in the north of Italy.
