de Chiloe" page 227.) In Europe, the most southern glacier which comes down to the sea is met with, according to Von Buch, on the coast of Norway, in latitude 67 degrees.

Now, this is more than 20 degrees of latitude, or 1230 miles, nearer the pole than the Laguna de San Rafael.

The position of the glaciers at this place and in the Gulf of Penas may be put even in a more striking point of view, for they descend to the sea-coast within 7 1/2 degrees of latitude, or 450 miles, of a harbour, where three species of Oliva, a Voluta, and a Terebra, are the commonest shells, within less than 9 degrees from where palms grow, within 4 1/2 degrees of a region where the jaguar and puma range over the plains, less than 2 1/2 degrees from arborescent grasses, and (looking to the westward in the same hemisphere) less than 2 degrees from orchideous parasites, and within a single degree of tree-ferns! These facts are of high geological interest with respect to the climate of the northern hemisphere, at the period when boulders were transported.

I will not here detail how simply the theory of icebergs being charged with fragments of rock explains the origin and position of the gigantic boulders of eastern Tierra del Fuego, on the high plain of Santa Cruz, and on the island of Chiloe.
