Discusses exchange of photographs with Édouard Claparède, "for whom I feel the highest respect".
Asks correspondent whether, when growing hollyhocks, he finds it necessary to space out the different varieties to prevent crossing and thus to obtain true seed [see Variation 2: 108].
Encloses strawberry blossoms used in his crossing experiments.
Sends CD seeds of Cattleya crispa as requested [see Collected papers 2: 77–8].
Anticipates success for his attempts to cross orchids artificially. Has not had a single seed germinate from a pod that was not produced by artificial crossing.
Conducted crosses on Gladiolus varieties exactly according to CD’s letter. Flowers of same variety are self-sterile, whether from the same plant or not.
Discusses unusual primula flowers and asks for details of Rawson’s experiments with gladioli. Asks for loan of Cypripedium but admits he will probably mutilate it.
Studying self-sterility, particularly in Oncidium, where abortion occurs consistently but stigma functions normally. His hybrid orchid crosses show sterility occurs capriciously. Thus it is not a "special endowment".
Disputes Asa Gray’s and Hermann Crüger’s view of rostellar germination.
Doubts absolute sterility of Catasetum.
Disappointed by results with homomorphic cowslips.
Provides evidence of self-sterility in Gladiolus.
Has observed three seed-leaves in some Dianthus seedlings.
Cannot cross, or grow from seed, Dielytra spectabilis.
JL’s review of Lyell’s Antiquity of man (1863) [Nat. Hist. Rev. n.s. 3 (1863): 211–19].
Owen’s review of W. B. Carpenter in Athenæum [28 Mar 1863, pp. 417–19].
Comments on MTM’s article ["On the existence of two forms of peloria", Nat. Hist. Rev. n.s. 3 (1863): 258–62]. Cites interesting case of peloric flower.
JL is off to visit Scotch "kjökken möddings".
Hopes Lyell is not really vexed by his article.
Has seen some curious hybrid ducks and geese of Bartlett’s. Bartlett will do experiments suggested by CD when he has time.
Preparations under way to move to London account for delay in thanking CD for his review [Collected papers 2: 87–92].
His book is finished, and he is sending a copy to CD; owing to the great expense few copies will be sent to reviewers.
Thanks HWB for his book [Naturalist on the river Amazons]. Feels sure it will often be alluded to in other works.
Asa Gray is fascinated by the "Butterfly paper" ["Contributions to an insect fauna of the Amazon valley", Trans. Linn. Soc. Lond. 23 (1862): 495–566].
The war is nearly finished, "rebeldom is ""gone up"" ".
Working on monstrous Primula. Is ovule anatropous as Asa Gray says, or amphitropous? Does he know natural path of pollen tubes in Primula. Can the tube enter the ovule by the chalaza?
Encourages JS to publish on sterility of orchids and to experiment on Passiflora.
Doubted Hooker’s poppy case.
Describes case of primrose with three pistils: when pulled apart allowed pollen to be placed directly on ovules. This supports JS’s explanation of H. Crüger’s case.
Thanks for CD’s Linum paper [Collected papers 2: 93–105].
Has not published much because he would be ignored as a gardener; hence he is looking for a foreign appointment.
Has prepared orchid sterility paper at CD’s suggestion [Trans. Bot. Soc. Edinburgh 7 (1863): 543–50].
Is ready to make some arrangement to repay CD’s bond. Has written to F. Ransome to help arrange repayment and wants CD to write his opinion of a fair scheme.
Hopes CD will finish and bring out his book on variation.
AG will publish extracts of H. W. Bates’s paper on mimetic analogy [Am. J. Sci. 2d ser. 36 (1863): 279–94].
