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

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.

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.

CD’s comments on JL’s paper [first part of "On the development of Chloëon dimidiatum", Trans. Linn. Soc. Lond. 24 (1863): 61–78].

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.

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.

Asks about insect fertilisation of Melastomataceae.

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.

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

Does not believe in regeneration of monstrous toe.

Pigeon and poultry experiments.

Peculiar pigeon at Philoperisteron [pigeon fanciers’ club].

Discusses the ill-will between England and U. S.

Considers the bases for deciding which plant species are "high" and which "low".

Comments on Alphonse de Candolle’s paper on oaks ["Étude sur l’espèce", Ann. Sci. Nat. (Bot.) 4th ser. 18 (1862): 59–110].

Encloses S. H. Scudder’s letter on Lepidoptera and fertilisation of orchids which identifies a butterfly with Platanthera pollinia adhering to it. Jokingly applies natural selection to butterflies acted on by orchid pollinia.

Grateful for CD’s commendation of his Glen Roy paper ["Parallel roads of Glen Roy", Q. J. Geol. Soc. Lond. 19 (1863): 235–59].

Reading Justus Liebig [trans. William Gregory, Animal chemistry or organic chemistry (1842)] has suggested that pattern of evolutionary succession might depend on differential need for soil minerals.

Naudin has not answered CD’s letter.

Reactions of Candolle, Naudin, Decaisne, and Gaston de Saporta to Origin.

CD’s new hothouse.

CD’s Linum paper.

JDH’s work on Welwitschia.

Asks CD’s views on TR’s observations that leaves breathe from their under-surfaces.

Peach-trees in hothouses cannot be kept in health unless fresh air is admitted so as to make its way under the leaves.

Continues his observations on the effect of environment on men – those migrating to America gradually assuming Indian-like features.

Thanks for CD’s experimental suggestions. Will count seeds of hybrid crosses.

Requests suggestions for Edinburgh Botanical Society expedition to British Columbia.

Cites [C. F.?] Burdach as the source of a note on atavism in alternate generations.

Wants to talk to CD about inheritance.
