Summary

Had read Tyndall’s letter [Nature 8 (1873): 399] – awfully savage, but certainly a great mistake to print it.

Thinks JDH will think better of Clerk Maxwell’s paper after he reads it.

Asks whether JDH could find out for him the temperature of rain in very hot countries.

Summary

Sends leaves and names by post.

Is writing everywhere for Drosophyllum.

Is deeply interested in Desmodium.

Had no intention of publishing on Nepenthes, the experiments were solely for CD’s "eating". Will continue with egg and raw meat experiments. Asks for advice on how to prove fluid is secreted by the glands.

Searles Wood’s letter is confused and would deny atavism if his principles were accepted.

Summary

Explains why he wants Drosophyllum.

Hopes JDH will be elected President of Royal Society.

Agrees with JDH on Greg’s Enigmas.

Would like Greg to visit Down if JDH comes as CD’s "protector".

Summary

Obliged for information on Mimosa albida; if a vigorous plant behaves as JDH says, CD’s notions are all knocked on the head.

Anxious to read Tyndall’s answer to Tait [Nature 8 (1873): 399].

Drosera story too long for his strength. Essentially the leaves act just like stomach of an animal.

Burdon Sanderson will give some grand facts at BAAS about Dionaea.

Offers to help JDH with Nepenthes experiments. Finds experimental work always takes twice as much time as anticipated.

Summary

Has had a week’s cessation of Nepenthes work.

Had to get out a paper for the Linnean Society on Thursday.

Has tried Mimosa albida in hothouse and found it wonderfully sensitive.

A military report from India praises his travel book.

Summary

Sends plant specimens.

He and Thiselton-Dyer, working on with Nepenthes, have independently found the spiral vessels going to the gland. CD’s view that the glands are secretory organs is suggestive. When Nepenthes is as much done as CD wants,

he will turn to Cephalotus and Sarracenia.

Summary

Drosophyllum arrived; none of his observations turned out as he expected, but nevertheless he understands its habits better than he did. The secreting hairs that he observed may be explained as a mere chemical reaction.

Comments on various articles he has read.

Asks for Thiselton-Dyer’s notes.

Summary

The Drosophyllum goes to Orpington by train this evening.

Summary

Mimosa too far gone to send now.

CD’s marjoram is the common [Origanum] vulgare, not the pot herb.

On the water injury, Thiselton-Dyer and he may have used too fine a spray, but plant is insensitive.

Horribly angry at P. G. Tait’s letter in Nature [8 (1873): 381–2].

Tyndall writes that he is strong – the next number of Nature will prove it.

G. Henslow is much better.

JDH leaves for Bradford [BAAS meeting] tomorrow.

Rejoices at CD’s success with Drosera; longs to be at Nepenthes.

Summary

Has three common garden plants of which he needs to know correct names; will send specimens as soon as he hears JDH is back.

Summary

Has been working hard on Mimosa albida. Could JDH ever make its opposite leaflets shut up close, as in sleep, when he irritated them? CD doubts they do, except in sleep. Thinks movement a protection against water.

Has examined only one specimen of Eucalyptus.

Cannot believe JDH’s results from cutting a hole in pitcher in his Nepenthes experiment.

Summary

He has noticed that Mimosa albida leaves closed only partially. It can be objected to CD’s theory that, if true, all, or at least more, species would close their leaves on application of water, unless he can show special injury done to M. albida by water.

Summary

Had thrown Geographical Society’s Proceedings in waste-basket, but as Strachey shows such admirable powers of discrimination he will fish it out and read the whole article.

Comments on 3d ed. of Sachs’s work [Lehrbuch der Botanik (1873)]. Wishes he were more controversial.

Has become wonderfully interested in Drosera and Dionaea.

9000 copies of Expression have been printed and most are sold.

Summary

Hopes Drosophyllum was all right.

Opinion of Council of Royal Society [on Presidency] is twelve for JDH, five for Duke of Devonshire, and G. B. Airy for William Spottiswoode.

Summary

Discusses experiments and observations on pitchers [of Nepenthes]. Suggests procedures for JDH to follow.

Any plant of any family with a terminal or with any lateral leaflets greatly reduced would be interesting to CD for studying spontaneous movements.

Has not received Eucalyptus or Acacia plants from Rollisson.

Summary

Thanks JDH and Thiselton-Dyer for useful information.

Is surprised Mimosa albida is not sensitive to water. Asks that they try again, or lend it to him.

Remembers a walk in Brazil in great bed of Mimosa.

After JDH left, CD was very bad, with much loss of memory and severe shocks continually passing through his brain.

Summary

Thanks for C. E. Norton’s address.

Tyndall’s answer [Nature 8 (1873): 399] has surprised and disappointed him;

great trouble in announcing Tyndall’s election as President Elect [of BAAS] yesterday. Tyndall may throw up the Presidency. Spottiswoode and JDH have concocted a letter telling him the facts.

A very poor dull meeting. Comments on papers by W. C. Williamson, Clerk Maxwell, David Ferrier, Burdon Sanderson [Rep. BAAS 43: lxx–xci, 23–32,126–7, 131–3].

Has heard Huxley is back quite well.

Summary

Thinks the Huxley fund should be done. Difficulty will be getting him to accept it.

Summary

Drosophyllum is coming from Dublin. Will ship it to Down when it arrives.

The awful honour of Presidency of Royal Society; his aversion to dignities and honours.

R. Strachey [Proc. R. Geogr. Soc. (1873): 450] has paid him and CD a compliment.

Letter from Gladstone.

Summary

Returned from visit.

Thinks several species of Eucalyptus would be worth experimenting on. Sends list.Mimosa albida would be worth its weight in diamonds. Neptunia worth more than diamonds.
