To H. B. Dobell   17 July [1864]1

Down. | Bromley. | Kent. S.E.

July 17th

My dear Sir

I write merely a line to thank you for your note.—2 The analogy of surnames had not occurred to me, only language generally, as has been well shown by Sir C. Lyell.—3

With respect to progression, I fear the argument wd not have much weight, unless a man was already convinced—

My dear Sir | Yours very faithfully | Ch. Darwin
