Dear Sir

I beg to thank very truly for your kind & very interesting answer to my queries.— The fact, which you communicate to me of a cock Rock Pigeon, having come to your Dove Cot & paired with a domestic Bird is of value to me.—² I had fancied from the several statements in poor M^r. Macgillvray’s work vol I p. 378 etc,³ that the taming of the Rock Dove was a much commoner event than it appears to be. M^r James Barclay certainly seems to believe that they have paired & bred in domestication.⁴ If you should ever hear of any cases, I sh^d. be extremely much obliged if you would kindly take the trouble to inform me.

I am making a collection of skeletons of all the domestic kinds of Pigeons, but I have failed in getting a real wild adult Rock Dove. Should you think me very unreasonable to beg you to do me the great favour to send one, in strong paper, or light Box per post: but I ask this on one condition that you will permit me to return you the 3^s or 4^s worth of Stamps. This would be a real assistance for I would skin it & keep skin with wing & leg on one side, & make skeleton of the rest.— To make the favour quite perfect, I sh^d. like just the head of a second specimen, as I cannot make skeleton & skin of this part from one specimen.—⁵ But I much fear that you will think me exorbitant in my request & that I trespass on your very kind offer of assistance.

I thank you for the information in regard to the drifted trees, it adds one more archipelago to my list.— If any fact should ever occur to you in regard even to any very slight variation or difference or Habits in regard to any of the domesticated animals of the Shetland Isl^ds. I sh^d. be most grateful for the information.— I sh^d. very much like to hear whether the bones of any large quadrupeds have ever been found deep in the peat of the Shetlands; for I suppose Peat is dug.—

You ask about myself; I have devoted my whole life to do what little I could for our favourite pursuit of Natural History, & I volunteered my Services on board H.M.S. Beagle in her circumnavigation, & did my best during our long voyage of five years, & published an account of it.—

With my cordial thanks, pray believe me, my dear Sir, Yours’ truly obliged | Ch. Darwin
