Sends copy of his Das Bewegungsvermögen der Pflanzen [1881]. Disagrees with CD about plant movement.
Thanks JW for book [Das Bewegungsvermögen der Pflanzen (1881)]. Discusses movement in plants.
Thanks for copy of Earthworms.
Responds to CD’s comments on his book [Das Bewegungsvermögen der Pflanzen (1881)].
Further comments on JW’s Das Bewegungsvermögen der Pflanzen [1881]. Discusses heliotropism and sensitivity of root tips. Bewildered by their differences concerning circumnutation.
CD has misunderstood his views on heliotropism. Agrees that his experiments on the movement of root tips are weak. Will conduct further research. Thinks that since mechanical conception of botany is not so widespread, those who agree with CD probably are in majority.
