  <dc:title>Draft letter, from Sir John Herschel to Thomas John Hussey</dc:title>
  <dc:description>Draft letter. Sending by the bearer mirror No. 3 of which he spoke. Will exchange it for Troughton's if Thomas John Hussey can make use of John Frederick William Herschel's. Do not attempt to clean Edward Troughton's mirror with acid. Hopes he does not feel obliged to carry out any particular series of observations.</dc:description>
