Summary

Asks to borrow J. J. Audubon [Ornithological biography (1831–9)].

Summary

Observes Plantago’s out-crossing mechanism.

Observations of style lengths of primroses and cowslips.

Summary

CD does not think he could be wrong about the stigma of Bolbophyllum.

Will not write up Drosera for years.

Praises JS’s experiments. Invites him to send a paper to Linnean Society.

L. C. Treviranus says all species of Primula present two forms except P. longiflora.

Summary

Enthusiastic about JS’s work on Passiflora self-incompatibility.

CD quotes JS on rostellar pollen germination [in "Fertilisation of orchids", Collected papers 2: 77–8]. H. Crüger attributes it to ants’ carrying stigmatic secretion to pollen.

Homomorphic cowslip seedlings are, sadly, showing variation.

Summary

Is having E. Suess’s essay [see 4284] translated; will forward it as soon as it is done.

Summary

Acknowledges the receipt of some signed transfers.

Summary

On behalf of her father, she asks that his name be put down for James Buckman’s testimonial. His cheque for £2.2.0 is enclosed.

Summary

Encloses flowers of Melastoma from Singapore.

Acclimatisation of plants.

Striped horses in London.

Bees’ cells; has been promised information from the East.

Summary

CD would be pleased to sit for a bust by Thomas Woolner for JDH, but he is too ill now.

Emma’s views on slavery and the Civil War.

Summary

Acknowledges receipt of JvH’s letters and report of his expedition. Congratulates him on its success.

Has sent Origin.

There is hardly a place in the world as interesting as New Zealand with respect to geographical distribution.

Will quote the case of the ducks that nest in trees.

Is working hard on Variation.

Summary

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].

Summary

CD agrees about reversion.

The discovery of crossing in cryptogams is very interesting.

Summary

Thanks JS for orchid paper [Trans. Bot. Soc. Edinburgh 7 (1863): 543–50]. JS presents excellent new facts on sterility of orchids.

His argument that coloured primroses are not hybrids is good, as is idea of discovering primrose parentage by breeding for colours.

Summary

CD thinks that he believes in as much migration as AdeC, only he does not believe nearly so much in continental extensions. CD also believes more in modification in form though he suspects the difference is not so great.

Thanks AdeC for information on melons, oranges,

and Swiss lake-habitation discoveries.

CD is almost tired of his book on variation under domestication, for his knowledge is insufficient to treat the plant part well, but he has done so much that he will finish it.

Summary

Apologises that CD is too unwell to do any work, but he is most interested in the frequent occurrence of inherited variations in one locality. It would have been a pleasure to visit if his health had permitted.

Summary

Defends position he takes on species [in Antiquity of man]. CD overestimates CL’s capacity to influence public. Will not dogmatise on descent of man; prepared to accept it, but it "takes away much of the charm from my speculations on the past". Cannot go to Huxley’s length with regard to natural selection. Responds to CD’s comments on Antiquity of man.

Summary

Encourages JS to continue work on coloured primrose. No one has noticed this since Gärtner. CD will send his own data for JS’s use and will read MS when ready. Advises JS to repeat experiments if evidence is weak – for his reputation’s sake and for satisfaction at fully establishing a fact.

Treviranus made a slip of pen in writing of Primula longiflora as short-styled.

Summary

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].

Summary

Received JDD’s book [Manual of geology (1862)]

and pamphlet on man ["On the higher subdivisions in the classification of mammals", Am. J. Sci. 2d ser. 35 (1863): 65–71].

Fully admits JDD’s objections are valid. But is convinced of the general truth of his own views (with much incidental error), because they embrace so many phenomena and explain them.

Discusses some mistakes Owen has made;

Falconer’s disagreement with Owen ["On the mammalian genus Plagiaulax", Q. J. Geol. Soc. Lond. 18 (1862): 348–69].

Summary

CD thinks HBD’s tables would be a considerable gain because "the importance of hereditary transmission can hardly be exaggerated from every point of view". Makes suggestions.

Asks him to send any remarkable cases of inheritance to him and, as well, any case of regrowth of amputated additional digit.
