When plans, calculated to be of general utility, are carried into execution with partial views, and upon interested motives, it is natural to attempt to confine, within some narrow circle, the advantages which might have been derived to the world at large, by an unreserved disclosure of all that had been effected. And, upon this principle, it has too frequently been considered as sound policy, perhaps, in this country, as well as amongst some of our neighbours, to affect to draw a veil of secrecy over the result of enterprises to discover and explore unknown quarters of the globe. It is to the honour of the present reign, that more liberal views have been now adopted. Our late voyages, from the very extensive objects proposed by them, could not but convey useful information to every European nation; and, indeed, to every nation, however remote, which cultivates commerce, and is acquainted with navigation: And that information has most laudably been afforded. The same enlarged and benevolent spirit, which ordered these several expeditions to be undertaken, has also taken care that the result of their various discoveries should be authentically recorded. And the transactions of these voyages round the world, having, in due time, been communicated, under the authority of his majesty's naval minister; those of the present, which, besides revisiting many of the former discoveries in the southern, carried its operations into untrodden paths in the northern hemisphere, are, under the same sanction, now submitted to the public in these volumes.
One great plan of nautical investigation having been pursued throughout, it is obvious, that the several voyages have a close connection, and that an exact recollection of what had been aimed at, and effected, in those that preceded, will throw considerable light on our period. With a view, therefore, to assist the reader in forming a just estimate of the additional information conveyed by this publication, it may not be improper to lay before him a short, though comprehensive, abstract of the principal objects that had been previously accomplished, arranged in such a manner, as may serve to unite into one point of view, the various articles which lie scattered through the voluminous journals already in the hands of the public; those compiled by Dr Hawkesworth; and that which was written by Captain Cook himself. By thus shewing what had been formerly done, how much still remained for subsequent examination will be more apparent; and it will be better understood on what grounds, though the ships of his majesty had already circumnavigated the world five different times, in the course of about ten years, another voyage should still be thought expedient.
