It is no longer, therefore, a doubt, that we have now a full knowledge of the whole circumference of this vast body of land, this fifth part of the world (if I may so speak), which our late voyages have discovered to be of so amazing a magnitude, that, to use Captain Cook’s words, _it is of a larger extent than any other country in the known world, that does not bear the name of a continent_.[17] 4. Tasman having entered the Pacific Ocean, after leaving Van Diemen’s Land, had fallen in with a coast to which he gave the name of New Zealand. The extent of this coast, and its position in any direction but a part of its west side, which he sailed along in his course northward, being left absolutely unknown, it had been a favourite opinion amongst geographers, since his time, that New Zealand was a part of a Southern continent, running north and South, from the 33° to the 64° of South latitude, and its northern coast, stretching cross the South Pacific to an immense distance, where its eastern boundary had been seen by Juan Fernandez, half a century before. Captain Cook’s voyage in the Endeavour has totally destroyed this supposition. Though Tasman must still have the credit of having first seen New Zealand, to Captain Cook solely belongs that of having really explored it. He spent near six months upon its coasts in 1769 and 1770[18], circumnavigated it completely, and ascertained its extent and division into two islands.[19] Repeated visits since that have perfected this important discovery, which, though now known to be no part of a Southern continent, will, probably, in all future charts of the world, be distinguished as the largest islands that exist in that part of the Southern hemisphere.
