Summary:
Has found the skull of the horned cock.
With regard to CD’s suggestion about the possibility of producing a pigeon breed with differently coloured sexes, WBT reports the results of crossing blue and silver dragons; the silver offspring are almost always hens.
Would like the latest edition of the Origin.
Encloses notes on volume one [of Descent].
Encloses a photograph showing the bleaching effect of the sun’s rays on dun feathers in pigeons.
