Summary

CD’s publisher is sending FJC an early copy of Insectivorous plants, in which he hopes that FJC’s admirable papers are acknowledged with the respect that they deserve.

Summary

Acknowledges presentation copy of Insectivorous plants.

Studying Drosera on vacation in Bohemia. Thinks CD has erred in considering "aggregation" to have occurred in the protoplasm. Suggests it is result of exosmosis of vacuole.

Summary

Responds to FJC’s criticism regarding "aggregation" as it occurs in protoplasm [see 10131].

Summary

Clarifies his thoughts on "aggregation" in Drosera.

Summary

Further discussion of the process of aggregation in response to [10137].

Summary

Has had doctoral student [Alexander Fraustadt] working on the physiology and chemistry (i.e., chlorophyll and starch distribution) and comparative anatomy of Dionaea.

Summary

Thanks FJC for paper by Alexander Fraustadt ["Vegetative Organe von Dionaea", Ell. Beitr. Biol. Pfl. 2 (1877): 27–64].

Mentions paper by A. W. Bennett ["Glands of carnivorous plants", Mon. Microsc. J. 15 (1876): 1–5].

Summary

Invites him to visit Down.

Summary

Acknowledges presentation copy of Cross and self-fertilisation.

Thanks for visit to Down.

Praise for CD’s theories.

Summary

Comments on paper by Francis Darwin ["Glandular hairs of the common teasel", Q. J. Microsc. Sci. 17 (1877): 169–74, 245–72].

Summary

Praises unbroken series of CD’s and Francis [Darwin]’s botanical works.

Confirms FD’s Dipsacus observations. Problem of interpreting microscopic filaments as protoplasm or as inorganic and osmotic artifacts.

Summary

Asks permission to publish comments by FJC regarding paper by Francis Darwin [see 11073].

Summary

Accepts CD’s offer to publish his letter, confirming Francis Darwin’s observations [see Collected papers 2: 205–7].

H. Hoffmann’s observations on Amanita contractile filaments must be repeated.

Microscopic examination of secretory gland filaments in Dipsacus leafcups. FD’s pseudopod theory of Dipsacus.

Summary

Sends details of H. H. R. Koch’s work on bacteria, including first photographs.

J. S. Burdon Sanderson’s and Koch’s collaboration on systemic fever.

Thinks movement of Francis Darwin’s Dipsacus filaments is an artifact.

Summary

Comments on discovery of micro-organisms in disease.

Describes experiments carried out by Francis Darwin on filaments of Dipsacus.

Summary

Comments on achenia of Pumilio argyrolepis.

Summary

Response to Movement in plants. Setting out to confirm CD’s experiments. Believes plant cell motion, like that of animals, depends on protoplasm more than water.

Summary

Thanks FJC for presentation copy [of Die Pflanze (1882)].

Summary

An account of his observations on Aldrovanda and Utricularia.

Sends CD his memoir on Aldrovanda [Beitr. Biol. Pflanz. 1 (1875) Heft 3: 71–92] in advance of publication [see Insectivorous plants, pp. 321 et seq., 395–6].

Summary

CD responds [to 9667] with description of his own effort to study Aldrovanda and his observations on the structure of Dionaea.

His admiration for FJC’s earlier studies of the Venus’s fly-trap.

He urges FJC to proceed promptly with publication of his memoir on Aldrovanda [Beiträge zur Biologie der Pflanzen 1, Heft 3 (1875): 71–92].
