Summary

Is preparing a volume of his articles [Essays on scientific and other subjects (1862)], to one of which he would like to add a postscript referring to CD’s Origin [pp. 100–1]. Sends proposed postscript for CD’s approval.

Summary

Illness has prevented his reading Origin. He has, however, expressed his [negative] opinion on the subject of mutability of species in his Manual of geology [1862]. Since his persuasions are so strong, he can do no less.

Summary

[Apparently in reply to question in missing portion of 3825.] A written agreement is unnecessary, but a letter stating terms would prevent misundertanding. He will attempt to have a review of HWB’s paper published.

Summary

Returns HH’s essay.

Summary

Discusses insects of south temperate S. America and New Zealand, especially with respect to the distribution and origin of Chilean Carabi, and has sent for a German monograph to learn about the eleven species he has found.

He refers to Chilean poverty in butterflies; scanty New Zealand insect fauna.

An analysis of south temperate insects is desirable, but the small English collections make him afraid to undertake it.

Summary

Is obliged for information concerning differences in the bees of Britain. Relates case of the Jamaican bees which were introduced long ago and have remained the same in size and character except that the diameter of the cells is larger, the wax tougher, and the walls of the hive thicker.

Summary

Can AdeQ verify the statement that the moths of the several races of the common silkworm are very similar?

When the female moth comes out of the cocoon, are her wings less developed than those of a male moth at the same stage?

Summary

Asks whether any correspondents have observed any sensible differences between the bees kept in different parts of Great Britain. CD has heard from several sources that breeds of bee in different areas vary.

Summary

In his work on cirripedes [Cirripedia, vol. 1 Lepadidae (1851), pp. 53–5] CD described a particular organ as an "auditory-sac" although he was unable to trace the supposed nerve from it to any ganglion. August Krohn [in "Observations on the development of the Cirripedia", Ann. & Mag. Nat. Hist. 3d ser. 6 (1859): 423–8] concluded that the organ was ovarian. CD supposes that Krohn is correct, but gives further observations that suggest an auditory function. If someone could find ova within the curious organ it would confirm Krohn’s view.

Summary

Orders paper suitable for drying plants.

Summary

J. P. Thom [of Home News] must change his position because of his health. Asks if CD can help find him a new situation.

Summary

Acknowledges CD’s approval of his review of Origin in Revue Germanique [16 (1861): 523–59; 17 (1861): 232–63]. Praises natural selection;

criticises C.-A. Royer’s [French] translation.

Summary

Jamieson has revisited Glen Roy and confirmed his theory of glacier lakes.

A. G. More considers CD the most profound of reasoners.

Summary

Asks if CD will have corrections for 2d German ed. of Origin.

CD’s theory only natural way to explain creation but contradicts current knowledge about origin of life from inorganic matter.

Has read Primula paper [Collected papers 2: 45–63] with interest.

Summary

Relates personal news about family members.

CD is "glad Glen Roy is settled".

Mentions evolutionary remarks on birds by Owen.

Compares variability among lower and higher organisms. Comments on Hooker’s view of the subject.

Forthcoming publication of Huxley’s book [Evidence as to man’s place in nature (1863)] and Lyell’s [Antiquity of man (1863)].

Summary

Thanks for Journal of researches and Origin.

Thanks CD for comments on his fern paper [see 3847 and 3853]; has great difficulty in expressing his ideas.

Discusses inheritance and variation.

Asks CD for an account of the experiments he would like JS to perform.

Summary

Gives reference to his observations on tendrils [Proc. Am. Acad. Arts & Sci. 4: 98–9].

Notes cases in which the pollen of the fertilising plant affects the form of the fruit of the fertilised plant, e.g., gourds and maize.

Discusses the Civil War and the attitudes of the English press.

Summary

Comments on HF’s paper on Plagiaulax from the Purbeck beds. Paper "dreadfully severe" on Owen.

"I am worse than ever in bearing any excitement."

Glad HF attacked Australian Mastodon. Never did believe in him.

Mentions Primula paper [Collected papers 2: 45–63].

Summary

Thanks for Aldrovanda reference and Cassia.

Has wasted labour on Melastomataceae without getting a glimpse of the meaning of the parts.

Wants seeds, from their native land, of Heterocentron or Monochaetum.

Is beginning to change his view about rarity of natural hybrids.

Summary

Louis Pasteur’s memoir "is a very able and convincing one" ["Mémoire sur les corpuscles organisés qui existent dans l’atmosphère", Ann. Sci. Nat. (Zool.) 3d ser. 16 (1861): 5–98].
