  <dc:title>Letter from [Captain William] Yolland, Ordnance Map Office, Southampton, to [Samuel Hunter] Christie, [Secretary of the Royal Society]</dc:title>
  <dc:description>Regarding Yolland's request for General Roy's theodolite observation books. These relate to his trigonometrical operations, which were published in the 'Philosophical Transactions' in 1787 and 1791. Yolland requires these papers as they would be helpful in the triangulation of London. </dc:description>
