1838. Charles Wilkes, United States Navy, in accordance with a bill
passed by Congress, set out on an exploring expedition to circumnavigate
the World. His programme included the investigation of the area of
the Antarctic to the south of Australia--the Australian Quadrant.
The squadron composing this American expedition first visited the
Antarctic regions in the American Quadrant, and then proceeded eastward
round to the Australian Quadrant from which, after a long cruise, they
returned, reporting land at frequent intervals in the vicinity of the
Antarctic Circle between longitudes 157 degrees 46' E. and 106 degrees
19' E. He shares with D'Urville the full honour of the discovery of
Adelie Land. Some of the supposed landfalls known to be non-existent.

1839. James Clark Ross proceeded south in charge of a scientific
expedition fitted out by the Admiralty at the instance of the British
Association for the Advancement of Science and approved of by the Royal
Society. His aim was to circumnavigate the Antarctic regions and to
investigate the Weddell Sea. The geographical results were fruitful;
the Ross Sea, the Admiralty Range and the Great Ice Barrier were
discovered and some eight hundred miles of Antarctic coastline were
broadly delineated.

1844. T. E. L. Moore was detailed by the Admiralty to supplement
the magnetic work of Ross and to explore to the southward of Africa
and of the Indian Ocean, but no additions were made to geographical
knowledge.

1872. Eduard Dallmann, whilst engaged in whaling with a German
steamer to the southward of America, added some details to the map of
the Palmer Archipelago but did not go further south than 64 degrees
45' S. Iatitude.

1874. The 'Challenger' scientific expedition, under the command of
George Strong Nares, in the course of their voyage from the Cape to
Australia during the circumnavigation of the World penetrated within
the Antarctic Circle in longitude 78 degrees 22' E.

1892. A fleet of four Scottish whalers cruised through the north
western part of the Weddell Sea. Scientific observations were made
by W. S. Bruce and others, but no geographical discoveries were
recorded.

1892. C. A. Larsen, master of a Hamburg whaler, added important
details to the geography of the American Quadrant of Antarctica on
the western side of the Weddell Sea.

1894. Evensen, master of another Hamburg wh
