To Francis Galton 13 December 
Down Bromley Kent
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 Mrs
Galton,5 pray believe me | Yours very sincerely | Charles Darwin
Thanks FG for comments [on Origin].
Acknowledges error involving rhinoceros.
Thinks female fowls select victorious or most beautiful cock.
