Copy letter from Herbert Rix, to John Newport Langley, Fellow of the Royal Society, Trinity College, Cambridge 'Dear Sir, The original blocks are never lent by us, but there is no objection to your having cliches taken from them by leave of Council, which I will obtain at their next meeting. I shall, however, put them at once in hand, and tell the printers to send their account for them to the University Press, which I suppose will be right? I am, yours truly, H Rix Asst. Sec. R.S. [Assistant Secretary, Royal Society]'. 13 April 1896
