Note 8 — ADDENDA.

Mr. Lyell, moreover, describes (Philosoph. Transact., 1835, p. 18), the rocks of gneiss on the beach near Oregrund in Sweden, as being so “smooth and polished, that it is difficult to walk on them.” Further on (p. 21), he describes the large bodies of ice, which are annually packed on this coast, so as to be eighteen feet thick: here then we have the same phenomena as in the Alps; and great icebergs in movement, instead of solid glaciers. More lately M. Berzelius has sent specimens of these rocks, “polished as if by emery in a constant rectilinear direction” (Edinb. New Phil. Journal, vol. 1., p. 313), to Paris, accompanied by a letter to M. Elie de Beaumont.
