Summary

Thanks CGE for gift of his latest work [Mikrogeologische Studien (1873)].

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

[Sir Joseph?] Whitworth’s contribution brings total to over £2000. Wishes CD could be persuaded to come to lunch with Huxley and Emerson.

Summary

Has decided to send the letter ["Variation of organs", Nature 8 (1873): 505].

Writes of his poor health and problems of settling in at Trinity.

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 for FH’s work on the means of the distribution of plants (Hildebrand 1873).

Summary

Sorry to hear of GHD’s poor health – he could have pleasant society at Cambridge if he were stronger.

Contributes £75 [to a fund for Naples Zoological Station] "if the affair goes on after we hear from Dohrn".

Summary

CD’s son [George] could do the work [of proof-correction for Descent, 2d ed.] if ARW finds he does not care for it.

Summary

Sends, with CD’s approval, a clarification of CD’s explanation of how useless organs might diminish [see 9061]. Using Quetelet’s law of normal distribution GHD shows how horns of cattle, having become useless, would gradually diminish and finally disappear.

Summary

Pleased CD enjoyed his book [Outdoor papers (1871)].

Rejoices at CD’s kindly feelings toward the coloured race.

The Index is in financial trouble due to F. E. Abbot’s unworldliness.

Agassiz is setting up a summer school for natural history off the Massachusetts coast. His pupils develop more liberal scientific opinions than Agassiz’s.

Encloses some notes on expression.

Summary

Is glad to hear LD’s translation [of Origin (1873–4)] progresses well.

Offers to send a photograph of himself.

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

On Nepenthes.

Asks JDH, if he publishes, to mention CD’s work on digestive powers of Drosera so that charges of plagiarism will not be made against CD later when he publishes.

Describes at length his observations on the movements of Desmodium.

Summary

Thanks JLGK for photos of natives of Queensland.

Asks if he can observe whether worms throw up castings in wet weather.

Summary

Comments on CHB’s book [Experimental researches on catarrhus aestivus – hay-fever or hay-asthma (1873)].

Explains that some pollens are wind-blown while others depend on insects for dispersal. Effect of pollen on skin and mucous membrane astonishing. Sends a book [M. Wyman, Autumnal catarrh (1872)].

Summary

Observations on bees’ biting holes in Lathyrus.

Suggests an experiment FD could carry out with Drosera.

CD is working on Mimosa, and "everything has turned out as perversely as possible".

Summary

Thanks for Indian [Medical] Gazette. Comments on article.

Summary

It is Huxley’s "duty to do what we wish him to do – his duty to his wife and children, his duty to us and to the world". Shares CD’s wish that Mrs [Henry] L[yell?] had not subscribed – it suggests the idea of an effort.

Summary

Thanks for sending WHF’s lecture, ‘On palaeontological evidence of the modifications of animal forms’ (Flower 1873).

Summary

Thanks RM for his paper on mimicry.

Cannot answer RM’s query because he believes it impossible to define large variations.

Believes monstrosities are generally injurious and are not often, if ever, taken advantage of in nature.
