Thinks of adding chapter on man to Variation. Asks about muscles connected to os coccyx in man and existence of other rudimentary organs in man.
Sends copy of Origin.

My dear Sir
Your kindness when I met you at the Royal Soc
The point on which I want information is in regard to any part which may be fairly
called rudimentary in comparison with the same part in the Quadrumana or any other
mammal.— Now the os coccyx is rudimentary as a tail,
& I am anxious to hear about its muscles. M
If you tell me anything about the os coccyx or other structures, I hope that you will permit me to quote the statement on your authority, as that would add so greatly to its value.— Pray excuse me for troubling you & do not hurry yourself in the least in answering me.
Pray believe me | My dear sir | Yours sincerely | Ch. Darwin
I do not know whether you would care to possess a copy, but I told my Publisher to send you a copy of the new Edit. of the ``Origin'' last month.—
- f1 5306.f1The year is established by the references to the Royal Society of London and to the presentation copy of Origin (see nn. 2 and 8, below).
- f2 5306.f2CD had attended a reception at the Royal Society on 28 April 1866 (Emma Darwin's diary (DAR 242)), where he met Turner. Turner then sent CD some of his publications (see letter to William Turner, 5 June  and n. 2).
- f3 5306.f3The reference is to Variation, which was published in 1868. Although CD began collecting material for a chapter on humans, he soon decided that the subject needed a separate volume and eventually the material was used in Descent (see Correspondence vol. 15, letter to J. D. Hooker, 8 February ).
- f4 5306.f4CD discussed rudimentary organs in animals and plants in Variation 2: 315--18, 397--8. He extended his discussion, including rudimentary organs in humans, in Descent 1: 17--31.
- f5 5306.f5William Henry Flower.
- f6 5306.f6The reference is to the Zoological Gardens of the Zoological Society of London in Regent's Park, London.
- f7 5306.f7Turner's response to CD's queries has not been found. CD included information from Turner on the muscles of the coccyx in Descent 1: 29--30.
- f8 5306.f8CD refers to the fourth edition of Origin, which was published in November 1866 (Publishers' Circular, 1 November 1866, p. 666). Turner's name appears on the presentation list for the book (see Correspondence vol. 14, Appendix IV).
