Thanks for "multitudinous" references.
Thanks Hooker for orchids.
Down. | Bromley. | Kent. S.E.
I thank you most sincerely for all the references. Good Heavens how do you know such multitudinous references! It is a horrid bore, that I shall probably find all my recent work done & done better than I have.— Anyhow I have enjoyed the work. If you had not told me these references how nicely you might have reviewed. ``disgraceful ignorance'' ``highly presumptuous'' &c &c—
I heartily thank you, though I expect to be heartily disgusted with the papers, when I get them. from Linn. Society.—
Please thank Hooker for information about Dendrobium Chrysanthum; & say that I sh

- f1 4329.f1The year is established by the relationship between this letter and the first letter to J. D. Hooker, 1 November  (Correspondence vol. 9).
- f2 4329.f2See Correspondence vol. 9, letter from Daniel Oliver, [before 8 November 1861]; this letter should now be dated [before 3 November 1861]. The references were to works on orchid structure and pollination; CD was working on Orchids in the latter part of 1861 (Correspondence vol. 9, Appendix II).
- f3 4329.f3Oliver was an editor of the Natural History Review, which began publication in January 1861; he had written a number of botanical reviews. Orchids was reviewed by Joseph Dalton Hooker in the October 1862 issue of Natural History Review, pp. 371--6 (see Correspondence vol. 10, letter from J. D. Hooker, 7 November 1862).
- f4 4329.f4CD frequently borrowed books from the library of the Linnean Society; see, for example, Correspondence vol. 9, letter to Richard Kippist, 7 January .
- f5 4329.f5CD had asked Hooker about the position of the labellum in Dendrobium in his first letter to Hooker of 1 November ; see also the letter to John Lindley, 1 November  (Correspondence vol. 9). Hooker's reply has not been found, but for CD's description of D. chrysanthum, see Orchids, pp. 172--8.
- f6 4329.f6CD had been investigating the ducts, or spiral vessels, of orchid flowers in order to determine homologies within the orchid family (see, for example, Correspondence vol. 9, letters to J. D. Hooker, 4 October  and 27 October ). In the first letter to J. D. Hooker of 1 November  (ibid.), he wrote that he did not have a Cypripedium `in spirits' to dissect for an examination of the ducts. For CD's discussion of the spiral vessels in orchids, including Cypripedium, and his accompanying diagram, see ibid., letter to J. D. Hooker, 8 November , and Orchids, pp. 290--305.
- f7 4329.f7CD mentioned the nectary of Evelyna in Orchids, p. 277; see also p. 295--6 n.
