Summary:
Publication of Earthworms delayed, but will send sheets to EK when he receives them [so that he can decide about publishing extracts in Kosmos].
Thanks for "Die Gegenwart".
"’Instinct’ of plants" is a most puzzling problem.
Does not see how mind can be defined "if we subtract consciousness".
