From Julius Wiesner 11 November 1881
Summary
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.
