Copy letter from Herbert Rix, to Professor Joseph Reynolds Green Rix encloses a cheque with a receipt to be signed and returned. As to Green's paper they had no information that he wished for a revise. It should have been returned to the Royal Society and not the printers in accordance with the printed slip attached to the proof. The paper is now printed and will appear in a day or two. It was carefully read in the office as well as by the printer's reader and Rix thinks Green will find it is correct. 17 September 1890
