New Holland is situated in the vast ocean extending to the south and east of the Spice Islands, and it lies about even with the lower part of the continent of Africa, only at an immense distance due east of it. Its extreme points of latitude are 39 degrees and 10 1/2 degrees S., and of longitude 112 degrees and 153 degrees 40 minutes E. from Greenwich, so that it includes in its huge extent climates both tropical and temperate, but none that are decidedly cold. It must be remembered, indeed, that the countries south of the equator become colder at the same latitude than those that extend towards the north; but, nevertheless, the nearest point towards the South Pole, 39 degrees, nearly answering to the situation of Naples in the northern hemisphere, cannot be otherwise than a mild and warm climate. The shape of New Holland is very irregular, its coast being much broken and indented by various great bays and smaller inlets; but it has been estimated to have a _width_ from E. to W. of 3000 miles, and a breadth from N. to S. of 2000, containing altogether not less than three millions of square miles. Of course, it is impossible, in so large an extent of country, that the interior parts of it should have been explored during the few years in which any portion of it has been occupied by Europeans. Accordingly, almost all the inland tracts are still a vast blank, respecting which very little is known, and that little is far from inviting. Indeed many hindrances oppose themselves to the perfect discovery of these inland regions, besides those common obstacles, to encounter and overcome which every traveller who desires to explore new, wild, and savage countries, must have fully made up his mind.
