Ice Chart of the Southern Hemisphere. ADMIRALTY CHART.

Ice Chart of the Southern Hemisphere.

London: The Admiralty, 1874, (but later). Chart diameter 61.5 cm, overall dimensions 87.5 x 69 cm. Large chart of the southern hemisphere extending up to the 30th parallel, original wash colour to seas, icebergs indicated in the map and coded by the month of their observation, a few circled by an old hand in red, official "Admiralty Chart Agent" ink stamp dated 9 April, 1902 to the lower right corner and a corresponding "received" stamp of the "Prin. Examiner Master & Mates Board of Trade" on the verso bearing the same date, a few other pencilled and inked annotations from the time also on the verso. Small tear with slight loss to the lower right corner of the sheet affecting some extraneous text, but not the chart, central vertical fold, occasional mild soiling, very good overall. "Originally prepared for production in 1866 by Staff Comr. F.J. Evans, and G.F. McDougall, Master R.N.", the data was compiled from previous voyages such as Cook's, Bellingshausen, Weddell and Ross amongst others as well as John Thomas Towson's work "Icebergs in the Southern Ocean" (1859) and other papers from the Hydrographic Office. As with many Admiralty charts, it was continuously updated and reissued with new information. This example has large corrections to April, 1897 and small corrections up to March, 1899. Nonetheless the chart appears to be uncommon with Copac listing just six copies of differing editions: the British Library holding five distinct editions dated between 1866 and 1931 and the National Maritime Museum holding another dated 1910. This important edition was issued right at the cusp of the golden age of Antarctic exploration. Item #30410
