Copy letter from Robert William Frederick Harrison, to Messrs J & C F Clay, Cambridge With reference to their recent conversation and to the fact that the early sheets of the supplementary volume of the catalogue [of scientific literature] have been returned to the Messrs for revision, Harrison details a system to follow in forwarding proofs and involving G Griffiths. The Society recognize that the Messrs would be justified in charging it with the extra expense to which they may have been put in re-casting these early sheets in accordance with the shortened scheme. 14 November 1898
