My dear Dr. Günther
I am very much obliged to you. The sight of the proofs haspleased me more than anything which has happened to me for someweeks.f1 Pray tell Mr Fordf2 (or show him this note) that I amdelighted with their appearance. I hope you are pleased with them,for they all illustrate facts which I give wholly on yourauthority. I declare I think the sexual differences in theChæmelions look more wonderful in the figures than in the realspecimens.f3 They will make my chapter capital. Pray tell Mr Fordthat I am excessively pleased, also, with the feathers, which lookfar better than I thought possible.f4 I long to see those of theArgus Pheasant & Peacock—f5 There ought to be a drawing of thehead of female salmon.—f6
Accept my cordial thanks for all your extraordinary kindness
Yours very sincerely | Ch. Darwin
The Callionymus also is beautiful.— I lately saw some onewho said he did not believe fishes ever differed much sexually!f7
