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".
