My dear Sir
I am sure that you have no cause to apologise to me; but rather I to you for so often plaguing you with questions.— I did not ask about young pigeon-down; but I am especially glad of this additional information, which I will give on your authority.1 What I asked about was whether you had any facts leading you to believe that it was any advantage with Hive-Bees to cross the breed, when the same stock has been long kept by same person in same place.2 But do not think of troubling yourself to answer.3 I am sorry that I did not bring in your name more clearly about the Bees-cells; but my volume was merely an abstract, & I quote no one in detail.4 If I live I hope to do more justice to all whom I quote.
Very sincere thanks for your kind offer of Poultry skulls, which I will most gladly avail myself of;5 but I am making very slow progress in my larger work, chiefly owing to a terribly long illness of my eldest daughter & my own poor health; so that I shall not attack poultry for some time.—6 I have seen notices of your most curious observations on the eggs of the Worker-Bees.—7 I am sorry to say that I am entirely ignorant with respect to the native country of the Italian Alp-Bee.—8
Pray believe me, My dear Sir, with thanks for all your kindness. | Yours very sincerely | C. Darwin
P.S. I have just remembered, what my other question was, namely whether it would be possible to procure for me trustworthy information, whether the duration of incubation is exactly the same in breeds of Pigeons so different as short-faced Tumblers, Runts, Carriers, or Pouters. Any fact on this head would be very valuable.—9
