Discusses results of geotropism experiment. Has started some heliotropic caustic experiments on mustard roots. Has trouble making marks.
Thanks JP for his kindness, but unfortunately the [unspecified] case is of no use to him.
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.
Last night had tremendous thunderstorm. Will ask Goebel about proshelismus. Describes experiments on beans. Please send Bessy’s address. Has got to know nice Englishman named Purdy and his wife. Bathes nearly every night with the Finlander.
Sends an enclosure [a statement of CD’s finances and estimate of the inheritance his children may expect] for HD and Ida to read; CD very pleased to be able to leave his children comfortably provided for.
