  <dc:title>Copy letter from an unknown correspondent, to the Cambridge Scientific Instrument Company</dc:title>
  <dc:description>In reference to their estimate of 30 May for Professor James Cossar Ewart's plates, which has not yet been accepted, they send six more figures included in an addendum to the same paper. Asks that they either send an estimate for the additional plates, of if the addition affects the other plates, for the whole number. Also asks when they may expect proofs.</dc:description>
