Copy letter from Herbert Rix, to Dr Gerald Francis Yeo, Fellow of the Royal Society 'Dear Sir, I have just heard from the communicator of Mr Robson's paper that it was intended only for Proceedings ['Proceedings of the Royal Society']. The only point therefore for you to decide is whether it should be published in full in the Proceedings. I enclose an abstract which may be of assistance to you: please return it. I am, yours faithfully Herbert Rix Asst Sec RS [Assistant Secretary, Royal Society]'. 4 January 1890
