In a paper published in the Quarterly Journal of the Geological Society for January, 1860, p. 178, I drew attention to the remarkable fact that in various parts of the world the presence of glaciers had been attended by a submergence of the land, and I suggested that the enormous weight of ice laid upon the surface of the country might have caused a depression, while the melting of the ice would also account for the rising again of the land which seems to have everywhere followed some time after the ice disappeared.
