Copy letter from Herbert Rix, to Charles Edward Groves, Fellow of the Royal Society Rix explains that the discrepancy noticed by Groves was a consequence of the fact that, under the great pressure of Government Grant work and soirée preparations, the circular requesting subscriptions, although dated 11 May, was written before that date and they had not checked for payments received in the meantime. His payment was received by the Royal Society's bankers on 2 May. 17 May 1889
