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.

Thanks JvH for his address [to the Philosophical Institute of Canterbury], his Geological Report [Topographical and geological exploration of the western districts of the Nelson province, New Zealand (1861)],

and for the "honourable" notice of Origin.

CD especially interested in JvH’s facts on the old glacial period.

Asks about fossil remains [of supposed living mammalia] which CD thinks may be like "the Solenhofen bird-creature" [Archaeopteryx].

Urges the recording of rate and manner of spreading of European weeds and plants and observation on which native plants "most fail".

Asks that a copy of Origin be sent to Thomas Rivers.

Curious about sale of Orchids. It is too stiff for the public. "If praise from Botanists would sell, it would go off well."

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.

THH’s efforts to obtain Copley Medal for CD fail. Thanks THH for kind words of sympathy.

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.

Impressed with TFJ’s Glen Roy paper.

TFJ has treated CD’s errors very gently.

Asks about insect fertilisation of Melastomataceae.

Has received the two trees sent by TR. Is anxious to see the fruit of the double peach.

The Origin is being sent.

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

Congratulations on marriage, which CD considers the best and only chance for happiness in this world.

Glad HWB is near completion of book.

Begs him to thank Wallace for Melastoma information; CD "cannot endure being beaten by a beggarly flower".

Asks FB’s help in identifying an article in The Field about the fins of fishes growing again after being cut off, and inquiring whether he has heard of the re-growth of organs in the mammalia or birds.

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 WBT ever heard of a case of the regeneration of monstrous (extra) toe on fowls?

Inquires about a curious pigeon reported at the Philoperisteron [pigeon fanciers’ club].

Does not believe in regeneration of monstrous toe.

Pigeon and poultry experiments.

Peculiar pigeon at Philoperisteron [pigeon fanciers’ club].

Remarks on the influence of pollen of one species or variety on the seed and fruit of another while still attached to the female plant. Refers to a remarkable case previously given by D. Beaton and asks whether Beaton will repeat the details.

[CD’s letter is followed by notes by D. Beaton in which he answers CD’s question, dissociating himself from some of his remarks, and in particular denying C. F. v. Gärtner’s claim that colour of one variety of pea can be changed by the direct action of the pollen of a different variety.]
