Falklands, etc.] this subject. In reference to this curious topic I would adduce, as corroborative perhaps of his speculations, the general geographical arrangement of those islands, whose botany I am about to describe as that of one country. They stretch from Fuegia on the west, to Kerguelen's Land on the east, between the parallels 45° and 64° of south latitude. Throughout this portion of the world the land exhibits a manifest tendency eastward, from the extreme south of the American continent; for there are no fewer than five detached groups of islands between Fuegia and Kerguelen's Land, but none between the latter island and the longitude of Lord Auckland's group, nor between this last again and the western shores of Fuegia and Patagonia.

Tierra del Fuego and the neighbouring southern extremity of the American continent appear to be the region of whose botanical peculiarities all the other Antarctic Islands, except those in the vicinity of New Zealand, more or less evidently partake. It presents a Flora, characterizing isolated groups of islands extending for 5000 miles to the eastward of its own position; some of these detached spots are much closer to the African and Australian continents, whose vegetation they do not assume, than to the American; and they are all situated in latitudes and under circumstances eminently unfavourable to the migration of species, save that their position relatively to Fuegia is in the same direction as that of the violent and prevailing westerly winds.

Tierra del Fuego itself is a crowded archipelago, forming the southern extremity of
