  <dc:title>Letter from Edward Sabine to Humphrey Lloyd</dc:title>
  <dc:description>The Academie des Sciences in Paris has led an effort to establish a magnetic observatory in the French colony of Algiers to operate in line with the British magnetic scheme. Instruments need to be ordered from, particularly, [Thomas] Grubb and [Thomas Charles] Robinson for this observatory. 

According to Sabine, a declination magnetometer by Grubb costs £35; a bifilar magnetometer by Grubb is £35; and a vertical force magnetometer by Robinson is £26, 5 shillings.</dc:description>
