MAP OF THE WORLD, from the Ptolemy Edition of 1548 (after Kretschmer's
_Entdeckungsgeschichte Amerikas_).--It will be observed that Mexico
is supposed to be joined on to Asia, and that the North Pacific
was not even known to exist.

RUSSIAN ASIA (after the Atlas published by the Russian Academy of
Sciences in 1737, by kind permission of Messrs. Hachette). Japan
is represented as a peninsula.

AUSTRALIA AS KNOWN IN 1745 (from D'Anville's _Atlas_, by kind permission
of Messrs. Hachette).--It will be seen that the Northern and Western
coasts were even by this time tolerably well mapped out, leaving
only the eastern coast to be explored by Cook.

AUSTRALIA, showing routes of explorations (prepared specially for
the present volume). The names of the chief explorers are given
at the top of the map.

AFRICA AS KNOWN IN 1676 (from Dapper's _Atlas_).--This includes
a knowledge of most of the African river sand lakes due to the
explorations of the Portuguese.

AFRICA (made specially for this volume, to show chief explorations
and partition).--The names of the explorers are given at the foot
of the map itself.

NORTH POLAR REGIONS, WESTERN HALF (prepared specially for the present
volume from the _Citizen's Atlas_, by kind permission of Messrs.
Bartholomew).--This gives the results of the discoveries due to
Franklin expeditions and most of the searchers after the North-West
