2nd. An examination of the shores of the GULPH OF CARPENTARIA. The real form of this gulph remained in as great doubt with geographers, as were the manner how, and time when it acquired its name.* The east side of the Gulph had been explored to the latitude of 17°, and many rivers were there marked and named; but how far the representation given of it by the Dutch was faithful--what were the productions, and what its inhabitants--were, in a great measure, uncertain. Or rather it was certain, that those early navigators did not possess the means of fixing the positions and forms of lands, with any thing like the accuracy of modern science; and that they could have known very little of the productions, or inhabitants. Of the rest of the Gulph no one could say, with any confidence, upon what authority its form had been given in the charts; so that conjecture, being at liberty to appropriate the Gulph of Carpentaria to itself, had made it the entrance to a vast arm of the sea, dividing Terra Australis into two, or more, islands.

[* I am aware that the president de Brossed says, "This same year also (1628) CARPENTARIA was thus named by P. Carpenter, who discovered it when general in the service of the Dutch Company. He returned from India to Europe, in the month of June 1628, with five ships richly laden." (Hist. des Nav. aux Terres Aust. Tome I. 433). But the president here seems to give either his own, or the Abbé' Prevost's conjectures, for matters of fact. We have seen, that the coast called Carpentaria was discovered long before 1628; and it is, besides, little probable, that Carpenter should have been making discoveries with five ships richly laden and homeward bound. This name of Carpentaria does not once appear in Tasman's Instructions, dated in 1644; but is found in Thevenot's chart of 1663.]

3rd. A more exact investigation of the bays, shoals, islands, and coasts of ARNHEM'S, and the northern VAN DIEMEN'S, LANDS. The information upon these was attended with uncertainty; first, because the state of navigation was very low at the time of their discovery; and second, from want of the details and authorities upon which they had been laid down. The old charts contained large islands lying off the coast, under the names of T' Hoog Landt or Wessel's Eylandt, and Crocodils Eylanden; but of which little more was known than that, if they existed, they must lie to the eastward of 135° from Greenwich. Of the R. Spult, and other large streams represented to intersect the coast, the existence even was doubtful. That the coast was dangerous, and shores sandy, seemed to be confirmed by Mr McCluer's chart; and that they were peopled by "divers cruel, poor, and brutal nations," was certainly not improbable, but it rested upon very suspicious authority. The Instructions to Tasman. said, in 1644, "Nova Guinea has been found to be inhabited by cruel, wild, savages; and as it is uncertain what sort of people the inhabitants of the South Lands are, it may be presumed that they are also wild and barbarous savages, rather than a civilized people." This uncertainty, with respect to the natives of Arnhem's and the northern Van Diemen's Lands, remained, in a great degree, at the end of the eighteenth century.

Thus, whatever could bear the name of exact, whether in natural history, geography, or navigation, was yet to be learned of a country possessing five hundred leagues of sea-coast; and placed in a climate and neighbourhood, where the richest productions of both the vegetable and mineral kingdoms were known to exist. A voyage which should have had no other view, than the survey of Torres' Strait and the thorough investigation of the North Coast of Terra Australis, could not have been accused of wanting an object worthy of national consideration.

PRELIMINARY OBSERVATIONS. (ATLAS Pl. I.)

Under the term WESTERN COASTS, is comprehended the space from the western extremity of the northern Van Diemen's Land to the North-west Cape of New Holland; and from thence, southward to Cape Leeuwin. The first is usually termed the North-west, and the second the West Coast: Taken together, they present an extent of shore of between seven and eight hundred leagues in length; lying in the fine climates comprised between the 11th and 35th degrees of south latitude.
