Wants to study hereditary mental characters to see whether they are limited by sex – an idea CD holds provisionally and which she doubts. She sends a questionnaire form that she asks CD to criticise. Has read Francis Galton [Hereditary genius (1869)].

Thanks CD for Insectivorous plants.

Is coming to London and hopes to visit Down.

Sorry he was out when CD called.

Sends a note on the ferment of the Nepenthes secretion, which he asks CD to forward to Nature if he thinks it worth while [see "Insectivorous plants", Nature 12 (1875): 251–2].

CD has been elected an Honorary Member of the Akademie.

Response to Insectivorous plants. Surprised that CD did not discuss origin of the contrivances. Critics will interpret them as inexplicable by theory of natural selection.

Insectivorous plants: observations on the digestive fluid of Nepenthes.

Reproduction of plant by "parthenogenesis".

Encloses corrections and notes on Variation [1st ed.].

Thiselton-Dyer has asked on CD’s behalf for results of experiments at Rothamsted on herbage of permanent meadow land. Sends report and tables of botanical analysis.

No new experiments on mutually sterile maize varieties since his paper in Botanische Zeitung in 1868.

His appreciation of Insectivorous plants, especially Utricularia section.

Has received but not yet read Insectivorous plants.

Regrets he is too busy to accept CD’s invitation to visit Down, but could only thank him again for saving the Zoological Station from shipwreck.

Italian translation of Variation will at last be published; will await second [English] edition to incorporate corrections.

Asks permission to translate Expression.

The second [Italian] edition of Origin is now in press.

JDH will arrive by train on Saturday.

Will be delayed on Saturday because of unveiling of a monument to Sir J. Franklin at Westminster Abbey.

Thanks for Insectivorous plants.

Believes Lepidoptera are of greater importance as fertilisers in alpine regions than in lowlands.

The famous stone pits of Ohningen are for sale.

Encloses copy of description of an outgrown stump. Refers to letter [missing] in which CD reports on a case of amputation. Would like to check J. Simpson’s cases before thinking everything is settled.

JDH reports his battle with Lord Henry Lennox over whether to locate new Herbarium on the Queen’s or public part of Garden.

Accepts offer of stereotype plates from Murray for Climbing plants, and will give same terms.

Has only just made Insectivorous plants ready. Long and favourable review just appeared in Times.

Wants to publish Variation and so will approach Judd & Co. [publishers of first U. S. edition (1868)].
