Summary

Henry Holland thought CD would be interested to know that Buxton’s brewery cannot go on with their own yeast, but are obliged to interchange with other breweries.

Summary

Is sending FM’s two letters on climbing plants as a paper to the Linnean Society ["Notes on some of the climbing plants near Desterro, in south Brazil", J. Proc. Linn. Soc. Lond. (Bot.) 9 (1867): 344–9].

Adaptations for pollination in Catasetum.

Summary

Sends photograph.

THH wishes he could write the popular zoology but writing is a boring and slow process when he is not interested, and he is overburdened with lectures.

Summary

Observations on Catasetum.

Figs require insects in order to set seed.

Summary

Comments on CD’s Lythrum paper [Collected papers 2: 106–31]

and on H. Crüger’s orchid paper [J. Linn. Soc. Lond. (Bot.) 8 (1865): 127–35].

May take position at Calcutta Botanic Garden.

Regrets he cannot be elected to Linnean Society.

Pleased Asa Gray has commented on JS’s paper.

Summary

His beard is darker than his hair, an exception to CD’s rule in Descent [2: 319]. Encloses sample of his hair, beard, and whiskers.

Summary

Discusses the powers of digestion of Drosera and why certain substances produce less excitement in the plant than others.

Summary

Thanks for interesting letter on climbing plants.

FM’s view on Anelasma seems probable.

Difficulty quoted by FM from A. Agassiz on embryology of Echinodermata is quite beyond CD.

Summary

ED writes on behalf of her husband, who is ill, to thank FH for his letter

and to thank [L. C.] Treviranus for his paper on orchids.

CD wishes to know whether Orchis pyramidalis grows in FH’s neighbourhood. He needs a fresh specimen to compare the stigma with those grown locally.

Summary

Thanks for presentation copy of Linum paper [Collected papers 2: 93–105].

Ficus experiments confirm CD’s supposition that insects visit Melastoma for nectar, but HC thinks pollen-seekers fertilise the flowers.

Maranta fertilisation.

Summary

Sends papers with comments. Convinced that the Aru pig is a species peculiar to New Guinea fauna, not a domestic animal that ran wild.

Admires CD’s paper ["Three forms of Lythrum", Collected papers 2: 106–31].

Summary

References to figures of Coryanthes.

Summary

Thanks CD for mentioning his Corydalis and Primula experiments in Variation.

Has become Professor of Botany at Freiburg.

Encloses specimen of Corydalis cava.

Summary

Has read and admires FM’s work on species.

Observations on Crustacea are good and original; asks FM to dissect and check some of CD’s observations on cirripedes.

Has sent "Climbing plants" paper [J. Proc. Linn. Soc. Lond. 9 (1865): 1–118] and would like to send Orchids.

Summary

Will observe fertilisation of melastomads as CD requests.

Observations on fertilisation by ants.

Detailed observations on sexes in Catasetum, which were made before he received Orchids and which differ from CD’s findings.

Summary

JDH should do as he likes with insectivorous plant materials.

He has always thought telling JDH what he has been doing was as good as publishing.

Cephalotus seems as horrid a puzzle as Utricularia.

Nepenthes will turn out a great job if the pitchers of different species act differently. JDH’s paper on Nepenthes [Rep. BAAS 44 (1874): 102–16] is too long for CD’s book. Well deserves a place in Philosophical Transactions.

Summary

Thanks for specimens [of insects].

Wonders whether difference between male and female plays part in fertilisation of fig.

Flowers of Oxalis sensitiva, sent long ago, are trimorphic and cleistogamic.
