Copy letter from an unknown correspondent, to [Messrs Harrison & Sons] With reference to Messrs letter of 28 September 1905 quoting a price for the supply of envelopes for the despatch of 'Proceedings [of the Royal Society]'. Asks it the Messrs will, in lieu of envelopes, quote a price per 100 for wrappers similar to those presently used, but broad enough to extend beyond the ends of the numbers of 'Proceedings'. 6 October 1905
