[122] This rock is very similar to the boulders and pebbles which we found on the beach at Point St. Mary (Freshwater Bay).

[123] The underwood is composed chiefly of Arbutus rigida—Berberis parvifolia and ilicifolia—(sempervirens of Banks and Solander). Veronica (decussata?) and, in moist places, Cineraria leucanthema, and Dysemore integrifolia; both of which are found in all the sheltered corners of Tierra del Fuego. No Fuchsia was seen, but Mr. Anderson gathered the sweet-scented Callixene marginata, and a species of Escalonia, on the hill sides.

[125] The Survey of this part now presents the navigator with the means of ascertaining his position, to a nicety, by angles taken with a sextant between Cape Horn summit and Jerdan's Peak, or Mount Hyde, and Kater's Peak; and if Jerdan's Peak and Mount Hyde be brought in a line, and an angle taken between them and Cape Horn summit, the operation will be still more simple.

[126] Miers, in his account of Chile, gives a table of barometrical measurements of the heights of the land between Valparaiso and Mendoza, from which it appears that he has deduced the height of Curacavi to be 1,560 feet. As my determinations are the results of observations made on my way to and from Santiago, I have no doubt of their correctness, and think that the registered height of Miers's table should be 29.355 instead of 28.355.

[127] The following are the results of the barometrical determination of the height of various points on the road between Valparaiso and Santiago:—

[128] Probably they are the same as we observed on the fish taken by us off Cape Fairweather, and which, I believe, to be nearly allied to the one that is figured in Cuvier's Règne animal, Plate XV. figure 5, a species of Lernæa, or Entomoda of Lamarck, iii. 233. The species is new.
