Down. | Bromley. | Kent. S.E.
My dear Wallace
The addresses which you have sent me are capital, especially that to the Rajah; & I have despatched two sets of queries. I now enclose a copy to you & shd 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.2 The subject is a curious one, I fancy I shall make a rather interesting appendix to my Essay on Man.3
I fully admit the probability of “protective adaptation” having come into play with female butterflies as well as with female birds.4 I have a good many facts which make me believe in sexual selection as applied to man, but whether I shall convince any one else is very doubtful.5
Dear Wallace | yours very sincerely | Ch. Darwin
