Copy letter from Robert William Frederick Harrison, to Professor Jacobsen, Deutsche Chemische Gesellschaft, Berlin In reply to Jacobsen's letter requesting the loan of blocks illustrating the paper by Professor Dixon in the 'Philosophical Transactions [of the Royal Society]' A 200, it is the Society's practice not to send out original blocks but to supply cliches of those required at the charge of the applicant. Unless he hears from Jacobsen to the contrary he will instruct the Society's printers to prepare cliches of the blocks of the figures Jacobsen quoted and to forward them with the bill for the same. The cost will probably not exceed 20 marks. 29 May 1905
