I am in receipt of your letter of the 25th December, and, in accordance with your desire, I am sending you herewith (by book post, registered) the manuscript of your paper "On Lunar Periodicities in Earthquake Frequency". I beg that that you will return the full paper to me, together with the modified abstract, at your earliest convenience, in order that the abstract may be set up in type without delay. Your letter was received during the Christmas vacation, hence the delay in replying.
I am, faithfully yours,
Asst. Sec. R.S. [Assistant Secretary, Royal Society]'.
