  <dc:title>Letter, from M. Macann to Sir John Herschel, dated at 56 Upper Seymour St.</dc:title>
  <dc:description>Autograph letter signed by sender. Has heard no more news of his paper; shall he write to the Royal Society [of London] for news? Comments on the claims of James MacCullagh for theories regarding light. Hopes to get something published by the London publishers so has written a paper on trigonometry, which he hopes John Frederick William Herschel will present to the Royal Society [of London] Doubtless John Frederick William Herschel is aware that there is no general proof for John Napier's rules.</dc:description>
