To Albert Günther 13 January 
Down. | Beckenham | Kent. S.E.
My dear Dr. Günther
I am very much obliged to you. The sight of the proofs has pleased me more than anything which has happened to me for some weeks.1 Pray tell Mr Ford2 (or show him this note) that I am delighted with their appearance. I hope you are pleased with them, for they all illustrate facts which I give wholly on your authority. I declare I think the sexual differences in the Chæmelions look more wonderful in the figures than in the real specimens.3 They will make my chapter capital. Pray tell Mr Ford that I am excessively pleased, also, with the feathers, which look far better than I thought possible.4 I long to see those of the Argus Pheasant & Peacock—5 There ought to be a drawing of the head of female salmon.—6
Accept my cordial thanks for all your extraordinary kindness
Yours very sincerely | Ch. Darwin
The Callionymus also is beautiful.— I lately saw some one who said he did not believe fishes ever differed much sexually!7
Delighted with proofs of illustrations [for Descent]. Hopes AG is pleased with them, as they illustrate facts given on his authority.
