In reply to your letter of Saturday the paper by Mr Marconi is not yet published, and the paper by Professor Fleming is not yet passed for publication, and possibly will not be published at all. When Mr Marconi's paper is published it will appear in Proceedings of the Royal Society.
I am, Dear Sir, faithfully yours,
Robt [Robert] Harrison
Asst. Sec. R.S. [Assistant Secretary, Royal Society]'.
