Gives CD an instance of facts that can be read either way as to whether a plant (Veronica humifusa) is a species or a variety.
Difficulty of distinguishing varieties and species. Did HCW suggest a printed list that might help?
Polymorphic genera.
Elaborates on his article ["A popular exposition of Mr Darwin on the origin of species", Macmillan’s Mag. 3 (1860): 81–92]. Was anxious to point out that CD’s method of investigation is philosophically correct. Asks permission to call.
Trip to Torquay.
Superiority of Journal of Horticulture to Gardeners’ Chronicle for CD’s purposes.
Seeks JL’s advice on the articles of partnership in the Southampton bank. CD and his solicitor fear they will be unfavourable to William.
Has worked out homologies of orchids’ pollinia and rostellum.
On W. H. Harvey’s review ["The natural evolution of organic species considered", Dublin Hosp. Gaz. 8 (1861): 146–52].
Thanks JL and his father for advice regarding Southampton bank. Has written to Atherley for fair terms.
Orchids from Kew.
JDH’s income problems.
Has been idling and enjoying the scenery.
"At dinner we were all sticking bits of ice together by their points, marvelling at the phenomenon and talking of you."

Thanks JL for assistance with William Darwin’s banking partnership; considers everything is now settled.
Is enjoying himself and doing a little work on orchids.
On orchids supplied by Kew; homologies of pollen and rostellum.
Puzzled by function of orchids’ rostellum.
Orchids’ pollen concentrated in two pollinia; hence one flower can fertilise only two others. This may explain precision of orchid pollination mechanisms.
