Copy letter from Herbert Rix, to William Topley, Fellow of the Royal Society 'Dear Mr Topley, I send you herewith, by order of Dr Foster, a letter received from Prof. Prestwich, together with his corrected proof, from which you will see how far he has carried out your suggestions. A revise containing these corrections has already been obtained from the printer, and I suppose we may now proceed to print off? Awaiting your answer, I am, yours truly, H Rix Asst. Sec. R.S. [Assistant Secretary, Royal Society]'. 5 October 1893
