Note 2 — Chapter IX · SENSITIVENESS OF PLANTS TO LIGHT: ITS TRANSMITTED EFFECTS.

Some erroneous statements are unfortunately given on this subject, in ‘The Movements and Habits of Climbing Plants,’ 1875, pp. 28, 32, 40, and 53. Conclusions were drawn from an insufficient number of observations, for we did not then know at how unequal a rate the stems and tendrils of climbing plants sometimes travel in different parts of the same revolution.
