Copy letter from Herbert Rix, to Professor George Howard Darwin, Fellow of the Royal Society 'Dear Sir, I have the pleasure to inform you that a sum of £30 (thirty pds [pounds]) was granted at the last meeting of Council from the Donation Fund to assist you in your work on Periodic Orbits. The cheque will be sent so soon as I can get the Treasurer's signature, which I fear will not be until the end of March, as he is at present on the continent. I am, yours truly, H Rix Asst. Sec. R.S. [Assistant Secretary, Royal Society]'. 27 February 1894
