Reference is sometimes made, in the course of the active discussion of the Glacial age in the Geological Magazine, to the Pleistocene of Canada, a country which, perhaps, as much as any other, in its great extent from the Atlantic to the Pacific, and from latitude 45° to the Arctic Sea, affords opportunities for the study of the deposits of this period. It has occurred to me, in connexion with this, that it might be useful to your readers to present to them a short summary of Canadian facts, as I think I have established them in publications on this subject, which are, perhaps, better known in this country than in England.

page 112 note 3 Proceedings of Canadian Institute, 1877. Dr. Hinde in this paper incorrectly states that the Leda Clay belongs to the “close of the Glacial Period,” and that boulder drift is not found above it. In truth, as Admiral Bayfield, Sir Charles Lyell, and the writer have shown, boulder-drift is still in progress in the Gulf and River St. Lawrence, though in a more limited area than in the Post-Pliocene period; but any considerable subsidence of the land might enable it to resume its former extension.
