To Francis Galton   13 December [1859]

My dear Galton

Your letter addressed to Ilkley reached me only this morning.¹ I must thank you sincerely for the pleasure which you have given me. Oddly enough your words are nearly the same as those used my Brother: I have received some very highly coloured compliments on my book, but none which have given me more pleasure than what you & my Brother have said.—²

Your correction about the Rhinoceros is an important one (but too late for the Reprint) & shall be attended to: I rashly assumed (having made enquiries about the Elephant in India) that the Rhinoceros would be quite safe.—

Thank you for the other notes: till I compare all my notes, I feel very doubtful about the share males & females play in sexual selection; I suspect that the male will pair with any female, & that the females select the victorious or most beautiful cock, or him with beauty & courage combined.—³

Several persons have been baulked about the ants: they do not notice that the Latin names change; but I have tried to make it clearer.—⁴

Again let me thank you sincerely for your very kind note & with our kind remembrances to M^rs.

Galton,⁵ pray believe me | Yours very sincerely | Charles Darwin
