To J. D. Hooker 26 [June 1860]
Down Bromley Kent
26th
My dear Hooker
Many thanks for your most interesting letter. I have often speculated loosely about Greenland, so shall be most curious to see your paper;1 as yet I have not digested your note.—
Etty makes a little progress certainly, but terribly slowly.—
My stomach has utterly failed; & I cannot think of Oxford; on Thursday I go for week of water-cure to “Dr Lanes, Sudbrook Park, Richmond Surrey”: please let me have line to say whether you will be at Kew on Thursday week July 5, or 6th or 7th; for on one of those days I shall return home & would come to Kew & spend one hour with you, with list of things to talk over & then by Railway home.— I should so enjoy this.—
I am very proud at being called a “spoiled Botanist”.
I have had such luck to day saw two small Hymenopterous insects (Sphegidæ?) licking labellum & when they crawled in they touched the rostellum & came out with the pollen masses fixed on forehead.—2 On one of them when dead I saw mark where anther had been fixed.— One very minute insect of same Family, which had no business to attempt to walk was caught & fixed to rostellum & was dying there!
I think I have made out whole process as far as insects are concerned in Listera.—3
I was so proud, I dissected the stigmatic horns in Gymnanedia4 & found it penetrated by hundreds of pollen-tubes, which I traced up to pollen.—
Farewell I will scribble no more.— I am very curious about homologies of anthers of Listera, & must get you to explain further.—
Farewell | C. Darwin

Going for hydropathy. Too ill for Oxford BAAS meeting.
Pollination by minute insects.
CD proves his view regarding Goodenia stigmatic surfaces by dissection and following pollen-tubes up to grains.
