Summary

Thanks AG for Cypripedium and Mitchella.

Plans to investigate pollination of Cypripedium.

Has finished Linum paper [Collected papers 2: 93–105].

Would welcome facts on "bud-variations".

Hears that Cinchona is dimorphic.

Summary

Sends Primula scotica and P. farinosa.

So far cannot fertilise Gongora atropurpurea although it is similar to Acropera luteola.

Experimenting on intergeneric hybrids to test CD’s view that sterility is not a special endowment.

Scott’s personal history.

Acropera capsule grows.

Plans for experiments CD has suggested on Primula, peloric Antirrhinum, and Verbascum.

Asks about Gärtner’s experiments on maize.

Aware of Anderson-Henry’s failures.

Through kindness of J. H. Balfour and James McNab, enjoys facilities for research. JS is in charge of the propagating department. Balfour almost engaged him to be superintendent of the Madras Horticultural Garden.

Summary

Acquired characteristics.

Huxley’s lectures: good on induction, bad on sterility, obscure on geology.

Asa Gray on slavery.

Falconer’s partial conversion.

Alphonse de Candolle on Origin.

Summary

Has forwarded FM’s MS to Max Schultze, but did not read it.

Movement of stem apex in Linum.

Haeckel’s paper on reproduction in certain Medusae.

Summary

Sailing date fixed for end of month. Beagle is beautiful. Details of instructions and route. Hopes voyage will not exceed four years. Quarters very confined. Considers Jenyns did wisely in not coming. If CD were longer out of college and some years older he never could have endured it.

Summary

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.

Summary

The cirripede material mentioned in CD’s letter of 10 Feb has not arrived. [Asks CD to inquire of Williams and Norgate, who forwarded it.]

Summary

Comments on EH’s forthcoming [Die Kalkschwämme (1872)].

Thinks EH is working much too hard.

Summary

Thanks for Hildebrand’s offer to translate Orchids into German, but H. G. Bronn had finished his translation before his death (Bronn trans. 1862). Has not yet received Hildebrand’s work on the distribution of coniferous trees (Hildebrand 1861). Asks that his compliments be presented to L. C. Treviranus.

Summary

Discusses the meaning of C. K. Sprengel’s term "dichogamy". Dichogamous plants are functionally monoecious; Primula is functionally dioecious.

Reports Hermann Crüger’s observations of Cattleya and of bees pollinating Catasetum. Crüger will observe Melastomataceae.

Has built a hothouse.

Fears Amsinckia cannot be dimorphic.

Ill health slows his work on Variation.

Summary

Indignant over Owen’s conduct as described in Hugh Falconer’s article on elephants ["On the American fossil elephant of the regions bordering the Gulf of Mexico", Nat. Hist. Rev. (1863): 43–114].

Summary

Thanks for information on expression.

Poor progress of civilisation in South Africa. CD’s doubts and fears about democracy.

JPMW’s views on glaciation in S. Africa will discredit him unless supported by clearest evidence.

Summary

Returns proofs; has no criticisms or remarks worth sending.

Summary

Observes Plantago’s out-crossing mechanism.

Observations of style lengths of primroses and cowslips.

Summary

Tells JS Acropera capsule should be left to grow.

JS was correct on "bud-variation" in fern frond.

Does not believe Primula structure necessarily related to dioecism, but the difference in fertility of the two forms forced him to admit the possibility.

Summary

Comments on his own review of Bates’s butterfly paper [Collected papers 2: 87–92].

Thanks AG for information on Platanthera.

Has been wasting more time with Melastomataceae; can find no nectar in Monochaetum; is there any in Rhexia?

Hopes Lincoln’s "fiat against Slavery" will have some effect.

Summary

Discusses dimorphic plants and the occurrence of "precocious fertilisation" in the bud.

Gives some comments on design in nature in the light of the translator’s commentary in the French edition of the Origin.

Reports the recent events of the Civil War.

[Note on verso of envelope:] Utricularia vulgaris is "about as neatly contrived for cross-fertilisation by insects as almost any orchid".

Summary

Suggests sending plant specimens. Asks about visit of Emma and the boys.

Summary

Sends Primula MS, which CD has promised to communicate to Linnean Society [see 4213].

Will soon send results on peloric Antirrhinum.

Summary

His admiration for HF’s paper on American fossil elephant.

Notes "temporary irruption of S. American forms into N. America".

Rejoices that HF has "smashed" case of Mastodon on Timor.

Shares HF’s anger at Owen.

He is eager to hear about fossil bird [Archaeopteryx].

Comments on criticisms of species theory by [Johann Andreas?] Wagner.

Describes research on fertilisation of Melastomataceae.
