I sent you a hasty card last night which I hope you understood. Professor Cajal will be here at 10 o'clock tomorrow morning to show his specimens. If you have any need to communicate with him before that, his address is, "C/O Dr Sherrington, 27 St George's Square, S.W." If this arrangement will not suit you, please telegraph to me to-day.
Asst. Sec. R.S. [Assistant Secretary, Royal Society]'.
