My dear Sir
Will you forgive my troubling you & give me if in your power a piece of information. In Braun’s Rejuvenescence2 p. 312 of your translation, there is a reference in note to “Godron de l’Espece et des Races”.3 I have in vain by Booksellers & others endeavoured to find out what this is, whether published separately or in some periodical. Again at p. 317 is it meant (in note) that there is extract of Hornsuch4 in the Flora of 1848; for if so I cd. then get the correct title for I have failed likewise in procuring this work. If you can give me any information by looking to the original German, I shd. be very much obliged & hope that you will kindly forgive my having troubled you.—
Pray believe me | My dear Sir | Yours very faithfully | Charles Darwin
