Returns proofs of GH's paper ["On hybridization among plants", Pop. Sci. Rev. 5 (1866): 304–13] with his criticisms. Prefers that GH not state that CD has read the proofs.
Does C. V. Naudin really say that ovules (not seed) of hybrid Luffa and Cucumis are imperfect?

My dear M
I have read over your Proofs, & have appended some criticisms.— I think your paper will do good by calling attention to subject. Several sentences appear to me to require making clear.—
It would really be of no use, I sh
Kindly tell me when the books are sent to 6. Queen Anne St & be so good as to direct them plainly. If sent there on Thursday morning I could get one of my servants who will be in London to call for them— But do not send them, if not finished with.—
In Haste | Yours very sincerely | C. Darwin
- f1 5118.f1The year is established by the relationship between this letter and the letter from George Henslow, 11 June .
- f2 5118.f2Henslow had sent CD the proof-sheets for an article on Charles Victor Naudin's research on hybridity (Henslow 1866b) with his letter of 11 June . For an indication of the nature of CD's comments, see the letter from George Henslow, [13 or 14 June 1866].
- f3 5118.f3In his letter to CD of 11 June , Henslow had asked whether he might add a postscript to his article, evidently acknowledging that CD had read it in proof.
- f4 5118.f4Henslow had reported that, according to Naudin, sterility in hybrids was a result of defective ovules (Henslow 1866b, p. 307). Henslow's article accurately summarised the discussion in Naudin 1863, pp. 181--2, as follows: `In order to account for the sterility of hybrids, M. Naudin remarks that we must, in all probability, go to the ovules to look for the cause, as the pistil often presents every sign of fertility, while the ovules, either all, or some only, remain abortive, as is the case with Luffa acutangulo + cylindrica and Cucumis Meloni + trigonus' (Henslow 1866b, p. 307).
