Abstract
THIS section was presided over this year by Colonel Sir Duncan A. Johnston, K.C.M.G., C.B., formerly director-general of the Ordnance Survey of the United Kingdom, and, as usual, the opening address dealt with matters of which the president had been made intimately cognisant through his life-work. After briefly referring to the additions made to geographical knowledge during the year by the journeys of Dr. Sven Hedin, Dr. Aurel Stein, and Lieut. Shackleton, Sir Duncan Johnston devoted the bulk of his address to the subject of topographical maps, considering specially the. preliminary triangulation for such maps, the methods of detail survey, the scale of the map, the scale of the field survey, the methods of representing details on the map, and the methods of reproduction. The address was printed in NATURE of September 9.
