C. DARWIN TO A.R. WALLACE

_Down, Bromley, Kent, S.E. March 7, 1860._

My dear Wallace,--The addresses which you have sent me are capital, especially that to the Rajah; and I have dispatched two sets of queries. I now enclose a copy to you, and should be very glad of any answers; you must not suppose the P.S. about memory has lately been inserted; please return these queries, as it is my standard copy. The subject is a curious one; I fancy I shall make a rather interesting appendix to my Essay on Man.

I fully admit the probability of "protective adaptation" having come into play with female butterflies as well as with female birds. I have a good many facts which make me believe in sexual selection as applied to man, but whether I shall convince anyone else is very doubtful.--Dear Wallace, yours very sincerely,

CH. DARWIN.
