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?

To George Henslow 15 [June 1866]
Summary
CD believes most strongly in reversion. J. G. Kölreuter’s, K. F. v Gärtner’s, and some of Charles Naudin’s cases leave no doubt in his mind. Forgets whether Herbert gave cases but in conversation he certainly believed in it. Thinks Gärtner is right to say reversion occurs only rarely in plant hybrids which have not been cultivated.

Has made observations on pollination mechanism in Medicago sativa [J. Linn. Soc. Lond. (Bot.) 9 (1867): 327–9], which his brother-in-law [J. D. Hooker] would accept. Wants to check that CD has not already made them.
Also sends interpretation of Salvia.
His observations come from following CD’s generalisation in Origin [p. 79] on necessity of out-crossing.
