ch. xlvi] Captain Cook — Bellingshausen 397 
reached the edge of the pack in 69 0 30', and in March, 
1820, arrived at Van Diemen's Land. In October of the 
same year he again sailed and kept to a high latitude, 
between 6o° and 67 0 , in the South Pacific. In January 
1821 he reached 70 0 , his furthest south, in Long. 92°io' W. 
a short distance to the eastward of Cook's furthest, but 
not so far south. On the nth of this month he discovered 
an island in 69°S.and 9i°W., nine miles long and ap- 
parently of very considerable altitude, but he was a long 
way off. He named it Peter Island. The discovery is 
important as indicating the extension of the continental 
shelf to that point. Alexander Land was sighted further 
east, in the same high latitude, but at a distance of 
40 miles. In July, 1821, Bellingshausen's expedition re- 
turned to Cronstadt.
