Your manuscript, with some detailed suggestions by the referee, was sent you, I believe, on September 25. Can you give me an idea when we are likely to have this back with your emendations that I may know whether it will probably be included in this volume of the "Philosophical Transactions" ['Philosophical Transactions of the Royal Society'], or more conveniently deferred to the next?
I am, yours truly,
Asst. Sec. R.S. [Assistant Secretary, Royal Society]'.
