My dear Dr. Frankland
I think that I have gained by long usage almost a prescriptive right to bother you!
I much want to ask you about a chemico-physiological point.2 Might I call on you at any hour, (early would suit me rather the best) on Monday or Tuesday, which are the only two days on which I am disengaged.—3 Ten or fifteen minutes would be ample time for me.—
Forgive me & believe me, Yours very sincerely | Charles Darwin
