My dear Sir

Thank you for your obliging offer of putting me on the list for the Council of the Geographical Soc: I should feel much interest in serving in that capacity, but I find that coming up to town robs me of so much time, that I fear I should scarcely ever attend & would therefore prefer not at present being put on the list; some future year I trust I shall have more spare activity

Yours very sincerely | Charles Darwin April 23^d.
