Ice-Action.—The subject of ice-action was considered in a paper read by D. Mackintosh, F.G.S. He first discussed the question whether the so-called continental ice of Greenland was a true ice-sheet formed independently of mountains, or merely the result of a confluent system of glaciers. He then considered the state of the surface of the Greenland ice-sheet, and believed that the amount of moraine matter was locally limited and of small extent. He defended the idea of the internal purity of existing ice-sheets, and gave reasons for doubting whether glaciers are capable of persistently pushing forward the large stones they may find in their beds, though he admitted that the base of glaciers is charged with finer débris, by means of which they grind and striate rock-surfaces. He mentioned that in the lake district of England he had never seen a sharply-bordered groove on a glaciated rock-surface which might not have been produced by a stone smaller than a walnut.

He saw no reason for doubting that re-
