Letter from Osbert John Radclyffe Howarth, British Association for the Advancement of Science, Burlington House, London, to the Secretary of the Royal Society At a meeting of BAAS Council, a letter from Colonel Grant of the Ordnance Survey was considered, on testing the conditions for primary triangulation in Great Britain. The suggestion was made for representatives of the Royal Society and British Association to discuss the matter with Grant. The British Association has made two nominations, but Howarth is not sure if the idea had been raised with the Royal Society. 10 February 1909
