Experiments to cut Laelia stigma from rostellum and then to fertilise rostellum are baffled by "a latent instinctive power". Somehow the pollen-tubes find their way to the style.

Suggests CD study variation in ferns.

Thanks for "Two forms of Primula" [Collected papers 2: 45–63].

Praise for Orchids.

Has sent copy of his paper to Asa Gray.

Melastomad flowers are strikingly neglected by pollinators.

Murray has ordered many illustrations for HWB’s Naturalist on the river Amazons.

His work on Mexico has some geology, which might interest CD.

He is currently at work on the "filiation des genres des espèces et des moeurs des guepes [hornets]".

Jaw with teeth found associated with Archaeopteryx fossil. Waterhouse pronounces it a fish’s jaw.

Discusses hybrid strawberry–raspberry

and his research on Primula and Linum.

Suggests breeding experiments.

Doubtful about Donald Beaton’s statement about Pelargonium.

Mentions experiments on peloric flowers.

If jaw belongs to Archaeopteryx, it will show great peculiarity. A German author has advanced the case as argument for Origin.

Has been copying out references from Natural History Review [possibly D. Oliver, "The structure of the stem in dicotyledons; being references to the literature of the subject", Nat. Hist. Rev. n.s. 2 (1862): 298–329].

Suggests DO study high incidence of separate sexes in freshwater plants.

Will be glad to have CD.

Sends some trees to CD.

Would be pleased to receive the copy of Origin offered by CD as gift.

Will give CD any tree or shrub he may want.

Refers to curious strawberry hybrids noticed in Journal of Horticulture [I. Anderson-Henry, "Crossing strawberries", J. Hortic. n.s. 4 (1863): 45–6].

Urges JS to publish on orchid pollen-tubes.

Suggests comparing stigmatic tissue of sterile hybrids and fertile parent; he would expect hybrid plant’s cell contents not to be coagulated after 24 hours in spirits of wine.

Suggests JS coat orchid stigmas with plaster of Paris for his work on rostellar germination.

Asks for list of "bud-variation" cases; CD has devoted a chapter to the subject.

Inquiries about I. Anderson-Henry’s observational competence.

The number of "aquatic" flowers is reduced if one considers only those that expand under water.

Lecturing at Norwich.

His son wants CD’s opinion about a cub supposed by Frank Buckland to be progeny of a lioness and mastiff.

Lyell working at last proofs [of Antiquity of man]; he is scornful of Owen.

Now recalls a Melastoma visited by some small Cetoniadae and bees (Xylocopa) in Malay Archipelago.

Wallace noticed that melastomads in Malay archipelago were visited by small Hymenoptera.

Darwinism discussed at the last meeting of the Zoological Society. The Darwinians had the best of it.

HWB has committed the "folly" of marriage [to Sarah Ann Mason, 15 Jan 1863].

Printing of vol. 1 [of Naturalist on the river Amazons] is nearly finished.

JDH delivers CD’s letter to C. V. Naudin.

Neither Naudin nor Decaisne appreciates Origin.

Discusses Naudin on physiological causes of species formation;

Decaisne on plant heredity.

JDH on Lincoln’s emancipation proclamation.

Asks about insect fertilisation of Melastomataceae.

Has done extensive plant hybridisation: strawberry, raspberry, Rhododendron.

Thanks CD for Origin.

TR has often thought naturalists do not pay enough attention to the effect of site, soil, and climate on animals and plants and "hence has arisen the enormous number of so-called species".

His observations on people of different counties.

Pleased that his book, Ch. Darwin’s Lehre [1863], has CD’s approval.

FR formerly a geologist, now a dealer in natural history objects.

Most active supporter of CD’s theory is Gustav Jäger in Vienna.

FR regards fossil Hipparion as a link between horse and pachyderms.
