  <dc:title>Letter, from Augustus De Morgan to Sir John Herschel, dated at 90 Guilford St.</dc:title>
  <dc:description>Autograph letter signed by sender. His paper on double stars is required for press so would be grateful if it could be sent along. The society is short of papers for reading so any John Frederick William Herschel can produce would be very welcome.</dc:description>
