In his second expedition, he resolved the great problem of a southern continent; having traversed that hemisphere between the latitudes of 40° and 70°, in such a manner as not to leave a possibility of its existence, unless near the pole, and out of the reach of navigation. During this voyage he discovered New Caledonia, the largest island in the Southern Pacific, except New Zealand; the island of Georgia; and an unknown coast, which he named Sandwich Land, the _thule_ of the Southern hemisphere; and having twice visited the tropical seas, he settled the situations of the old, and made several new discoveries. But the voyage we are now relating is distinguished above all the rest by the extent and importance of its discoveries. Besides several smaller islands in the Southern Pacific, he discovered, to the north of the equinoctial line, the group called the Sandwich Islands; which, from their situation and productions, bid fairer for becoming an object of consequence, in the system of European navigation, than any other discovery in the South Sea. He afterward explored what had hitherto remained unknown of the western coast of America, from the latitude of 43° to 70° north, containing an extent of three thousand five hundred miles; ascertained the proximity of the two great continents of Asia and America; passed the straits between them, and surveyed the coast, on each side, to such a height of northern latitude, as to demonstrate the impracticability of a passage in that hemisphere, from the Atlantic into the Pacific Ocean, either by an eastern or a western course. In short, if we except the sea of Amur, and the Japanese Archipelago, which still remain imperfectly known to Europeans, he has completed the hydrography of the habitable globe. As a navigator, his services were not perhaps less splendid; certainly not less important and meritorious. The method which he discovered, and so successfully pursued of preserving the health of seamen, forms a new æra in navigation, and will transmit his name to future ages amongst the friends and benefactors of mankind.
