Comments on CD’s book [Movement in plants].

Continues with his experiments with ripple-marks.

Is in despair about his astronomy.

Behaviour of pigeons is now different from that described in Beresbith Raba, a 3d century gloss on Genesis.

Expresses doubts that pigeons could rest one wing during flight.

Glad GHD goes on with ripple-marks; if he makes out a theory of ripples, they might give important information about the most ancient deposits.

CD has been wonderfully glorified in the Times [review of Movement in plants, 20 Nov 1880].

Some sheets [of Movement in plants] are missing. Is delighted with its "lesson of methods of observation patience and thought".

Thanks for Movement in plants.

Condolences on S. E. Wedgwood’s death.

Thanks for book [Movement in plants].

The use of earthquakes as a geological cause in his previous letter was careless.

Shelly beach deposits over considerable distance from Ireland to Scotland seem better explained by high sea-level than low land.

Only CD seems to have reported shattered rocks under the Moel Tryfan drift.

Wishes to see CD.

He has been proposed as Professor of Geology at the University of Moscow.

Praise for Movement in plants, lately arrived.

Praise for Wallace’s Island life

and astonishment that he could be a spiritualist.

Differs with Wallace on age of SW. Australian flora. JDH ascribes its peculiarities to isolation by an inland sea.

Very pleased by JVC’s note about Movement in plants. Feared he would find it intolerably dull. Some missing sheets are being replaced. Also sends a perfect copy.

Thanks CD for copy of Movement in plants and says he is enjoying it. Is pleased that a full article appeared in the Times. Will go to Beaulieu soon for worm casts. His gardener calls worms “our civil engineers”. Promised to tell Frank how to make plants bend.

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.

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.

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.

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.

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

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.

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.

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.
