To J. S. Henslow 16 July 
at Miss Wedgwoods | Hartfield | Tonbridge Wells
My dear Henslow
I thought it wd be better to write direct to Daubeny & tell him there was nothing direct on subject in my Book.— 1 I did not see much in his paper.—2 The frequency of “Sports” ie modified buds in plants goes direct against his view.3 There is no greater mystery in the whole world, as it seems to me, than the existence of sexes,—more especially since the discovery of Parthenogenesis.4 The origination of sexes seems beyond all speculation.— Nevertheless I quite agree with your remarks in answer to Daubeny.—5
I am glad to hear Mrs Barnard’s affair is safely over.—6
How successful your Fete seems to have been!—
In Haste | My dear old Master | Yours affect. | C. Darwin
I did not hear of poor FitzRoy with the Bible at the Geographical Section—7 I think his mind is often on Verge of insanity.—
Discusses Charles Daubeny’s views on sexuality of plants [Rep. BAAS 30 (1860) pt 2: 109–10]. "There is no greater mystery in the whole world, as it seems to me, than the existence of sexes, – more especially since the discovery of Parthenogenesis."
Says apropos of the FitzRoy Bible incident [at Oxford BAAS meeting], "I think his mind is often on verge of insanity."
