To Osbert Salvin 12 October 
Down, | Beckenham, Kent.
My dear Mr. Salvin
You have been very very kind. I do assure you that I had not the least intention to cause you so much trouble & to waste so much of your time. When I saw your bundle of observations, I felt as if I had committed theft, arson or murder.—1 Although I can give only a page or so to the subject your notes will be very useful, & will save me from at least one blunder. Is not the structure of the beak of the Shoveller quite beautiful?—2 it filled me with admiration. I have the beak of Malacorhynchus which is nearly as perfect as that of Spatula, but not quite so.—3 You give me plenty of facts for the lower end of the series.— I have got some observations on the habits from Mr Bartlett.4 Let me again cordially thank you.— My comfort is that so careful an examination can hardly fail to come in some day of use to you. Shall I not return your notes in about a month’s time, when my M.S. is printed?5 If you desire it, send me a card to this effect | Believe me | Yours very sincerely | Ch. Darwin
CD appreciates the great trouble OS has taken in providing a bundle of observations. [See 8001.] They are useful and will save CD from at least one blunder.
The structure of the beak of the shoveller "filled me with admiration".
