To Samuel Birch 6 April 
Down Bromley Kent
My dear Sir
You formerly gave me some valuable extracts about Poultry from Chinese Encyclops.—1 I shd. be so much obliged if you could answer me 4 questions on enclosed paper. You might affix “yes” or “no” & “date” & return the paper, without troubling yourself to write. I enclose your old memorandums, as they will recall the Books in question.
Pray forgive me being so troublesome & believe me | My dear Sir | Yours sincerely obliged | Ch. Darwin
I enclose directed envelope so as to give as little trouble as possible.
What is probable age of the Japanese Encyclop? (marked with single red line)2
Am I right in believing that the Santsae or Chinese “Encyclop. of Three Principles”, was compiled from other ancient works? I think you told me so.— Is this the case also with the Puntsaon?3
You give in note (marked with 2 red lines) an extract about Fowls with black feathers & bones. Is anything said about the feathers being hairy. I wish much to know, as I have extraordinary case of reversion in this breed.—4
Pickering in his Races of Man p. 374 speaks of a Head & neck of Fowl in a tribute-procession to Thouthmosis III. Can you tell me date of this King?5
Requests information about Japanese and Chinese encyclopedias,
about the rarity of fowls with black feathers,
and about date of the king Thouthmosis III.
