Note 5 — ADDENDA.

We might expect that they would sometimes be launched into the deep, whilst on their passage. M. Charpentier (Edinburgh New Phil. Journal, vol. xxi., p. 217) observes, speaking of another theory, “This view is equally insufficient to account for the extraordinary position of immense single blocks, which we sometimes find planted vertically in the soil, in the valleys, as on the sides of a mountain, and split up throughout their whole extent from top to bottom,—a phenomenon which would force us to believe that these blocks, had fallen perpendicularly from a certain height on the very spots where we now see them, and had been rent asunder by the fall, into the several fragments lying near one another.” M. Charpentier considers this owing to the fragments having fallen through fissures in the enormous glaciers, which, as he believes, extended from the Alps, across the lake of Geneva, and up the Jura. The explanation above suggested is, at least, as simple as this.
