To Francis Darwin 12 July [1879]
Summary
Notes observations on sensitivity and movement of radicles.
Has finished chapter [of Movement in plants] on sleeping plants and is now looking over heliotropism notes.
Is perplexed by Erasmus Darwin; Erasmus [A. Darwin] likes it, but Henrietta thinks it much too long.

To Francis Darwin 25 June [1879]
Summary
Suggests experiments to test the response of radicles to light. Considers an alternative term for heliotropism.
Will be curious to have FD’s spiral theory about circumnutation explained to him.

Summary
Stresses importance of ensuring that cauterisation of radicles does not, through injury, prevent movement. Plans an experiment to test for "apheliotropism" in certain radicles.

To Francis Darwin 28 June [1879]
Summary
Discusses the movements of radicles. His observations show that sensitivity to touch resides in the root tip and he believes that sensitivity to gravity governing geotropic responses is also in the root tip. Would much like to convert Julius von Sachs to his ideas on radicle movement.

To Francis Darwin 2 June [1879]
Summary
Thanks for FD’s letter describing microscopic work under experienced supervision.
Is glad to hear of C. E. Stahl’s objection to treating plants as mere machines.
Pleased that J. von Sachs has yielded on growth.
Perhaps Stahl will recognise whether the case of the silver fir is the same as that referred to in the German account [see 12074b].
CD has finished the first draft of his essay on Erasmus Darwin’s life and is "heartily sick of the job".

Summary
FD’s experiment shows that caustic does not interfere with the bending of radicles. Believes that the apex is a kind of brain for certain movements, being specialised to receive certain irritations.
