My dear Sir
I shd. very much like to hear your paper on Decr 9th,2 but at present owing to the state of Mrs Darwin’s health it is impossible for me to leave home. This has prevented my attendance at the Philo-perist. last time & it will next time.
What a very odd & curious fact about the colours & absence of down—it is quite new to me: I fear that I have no birds of these colours matched to observe it in. It really strikes me as very curious, & I shall be curious to ask Mr H. Weir how often he has observed it, & in what breeds; but this I can do at some future Philo-peristeron.—3
Your confirmation seems a strong one. Unfortunately I killed but the other day two yellow Tumblers.— Many thanks for your kind offer of Brunswicker, but I do not think the Breed distinct enough to be worth crossing.—
No news yet of the Persian Pigeon;4 but I have just heard of large collection of skins for me from further S. on W. coast of Africa.5
Yours very sincerely | Ch. Darwin
I hope that you are getting on well with your Poultry Book; I have seen only the 1st. nor., as my Bookseller has neglected to send them; but I must touch him up.—6
