  <dc:title>Copy letter from William Bate Hardy, Secretary of the Royal Society; to [Augustus Desire] Waller, FRS</dc:title>
  <dc:description>Writes in order to be clear as to the facts under controversey concerning the 'crescograph'. Explains that, to him, there seems to be no question as to the merit of the instrument and its capability of magnifying variations of length. Reminds Dr. [Augustus Desire] Waller that this was vouched for by a member of the Committee who investigated the apparatus at University College. </dc:description>
