The lands discovered in the Antarctic regions, by Captain Smith, of Blythe, in the brig Williams, have been the subject of various papers in the different periodical works which pay attention to such subjects. The Literary Gazette furnished the first notice of this discovery, and, not long after, one of the Edinburgh Magazines supplied some farther particulars, which we copied into our pages. There has not yet, however, appeared any full and regular history of the new land, of which maps and charts are now selling in all the principal shops in London.
