  <dc:title>Letter from Balfour Stewart, Kew Observatory to Edward Sabine</dc:title>
  <dc:description>Refers to observations made with Captain Blakiston’s unifilar and dip circle, and discusses the instruments including the azimuth compass. Stewart intends to take ‘one or two more observations with’ [Blakiston’s] instruments. Stewart asks Sabine to inform him beforehand ‘if Jones unifilar is to go to [Colonel] Smythe’.</dc:description>
