Summary

Admires Wallace’s Island life.

Criticises: 1. His view of similar plants on distant mountains – CD prefers previous low-land connections to Wallace’s summit–summit dispersal;

2. Source of warmth for ancient Arctic climate;

3. Origin of S. Australian flora.

CD’s favourite cases in Movement in plants.

Summary

Has learned of death of Sarah Elizabeth Wedgwood, former proprietor of Tromer Lodge, and writes about his deceased father’s earlier attempts to purchase this property. Requests information on any future transfer of it.

Summary

WTT-D’s suggestion about absorbent function of pegs in Abronia suggests origin of pegs in Welwitschia, which deeply interests CD. Previously could not see how pegs became large enough to be of mechanical use. Now thinks tissue between hypocotyl and radicle absorbs fluid, which would favour rise of peg to expose larger surface.

Rejects German contempt for investigating use of organs.

Asks WTT-D to observe how worms draw Robinia leaves into burrows.

Summary

Discusses GHD’s ripple theory. Asks him how they are formed.

Delighted to hear that light is dawning in GHD’s eyes on the planetary system.

Summary

Wishes to read CD’s books; will not do so without an assurance of CD’s faith in the New Testament.

Summary

He has proved that heat is generated by the exudation of oxygen from roots, and that there is continuous electrical action from leaves to roots.

Summary

Finds CD was correct in Variation: hybrid bees tend to sting more often than pure-bred bees.

Preparing a second edition of the chapter on the origin of cultivated plants in his Géographie botanique. The work done since 1855 confirms his opinions.

Summary

Asks WED to observe whether worms consistently draw acacia leaves into their burrows with a particular end first.

Will soon know whether he will need worm-castings from Beaulieu.

Summary

CD may not mean same thing as WTT-D by absorbent pegs in Abronia.

F. O. Bower’s paper on Welwitschia [germination] [Q. J. Microsc. Sci. 21 (1881): 15–30] will appear in January.

Has observed earthworms for CD: they do not draw Robinia leaves into burrows by the petioles.
