There will be a farther use in giving such an abstract a place in this introduction. The plan of discovery, carried on in so many successive expeditions, being now, we may take upon us to say, in a great measure completed, by summing up the final result, we shall be better able to do justice to the benevolent purposes it was designed to answer; and a solid foundation will be laid, on which we may build a satisfactory answer to a question, sometimes asked by peevish refinement, and ignorant malevolence, What beneficial consequences, if any, have followed, or are likely to follow, to the discoverers, or to the discovered, to the common interests of humanity, or to the increase of useful knowledge, from all our boasted attempts to explore the distant recesses of the globe? The general object of the several voyages round the world, undertaken by the command of his majesty, prior to that related in this work, was to search for unknown tracts of land that might exist within the bosom of the immense expanse of ocean that occupies the whole southern hemisphere. Within that space, so few researches had been made, before our time, and those few researches had been made so imperfectly, that the result of them, as communicated to the world in any narration, had rather served to create uncertainty, than to convey information; to deceive the credulous, rather than to satisfy the judicious enquirer; by blending the true geography of above half the superficies of the earth with an endless variety of plausible conjectures, suggested by ingenious speculation; of idle tales, handed down by obscure tradition; or of bold fictions, invented by deliberate falsehood. It would have been very unfortunate, indeed, if five different circumnavigations of the globe, some of them, at least, if not all, in tracks little known, and less frequented, had produced no discoveries, to reward the difficulties and perils unavoidably encountered. But the following review will furnish the most satisfactory proofs, that his majesty's instructions have been executed with ability; and that the repeated visits of his ships to the southern hemisphere, have very considerably added to our stock of geographical knowledge. 1. The south Atlantic ocean was the first scene of our operations. Falkland's Islands had been hitherto barely known to exist; but their true position and extent, and every circumstance which could render their existence of any consequence, remained absolutely undecided, till Byron visited them in 1764. And Captain Macbride, who followed him thither two years after, having circumnavigated their coasts, and taken a complete survey, a chart of Falkland's Islands has been constructed, with so much accuracy, that the coasts of Great Britain itself, are not more authentically laid down upon our maps.
