The Three Voyages of Captain Cook Round the World, Vol. III (of VII‪)‬

Excerpt: "Whether the unexplored part of the Southern Hemisphere be only an immense mass of water, or contain another continent, as speculative geography seemed to suggest, was a question which had long engaged the attention, not only of learned men, but of most of the maritime powers of Europe. To put an end to all diversity of opinion about a matter so curious and important, was his Majesty’s principal motive in directing this voyage to be undertaken, the history of which is now submitted to the public. But, in order to give the reader a clear idea of what has been done in it, and to enable him to judge more accurately how far the great object that was proposed has been obtained, it will be necessary to prefix a short account of the several voyages which have been made on discoveries to the Southern Hemisphere prior to that which I had lately the honour to conduct, and which I am now going to relate. The first who crossed the vast Pacific Ocean was Ferdinand Magalhaens, a Portuguese, who, in the service of Spain, sailed from Seville, with five ships, on the 10th of April, 1519. He discovered the Straits which bear his name; and having passed 4through them on the 27th of November, 1520, entered the South Pacific Ocean."
