Some naturalists have supposed tendrils to be endued with some degree of perception, to which their propensity to approach neighbouring objects may be ascribed; and though others who have written on the same subject may have rejected this hypothesis, it does not appear to Mr. Knight that any direct experiments have been made similar to those which he here describes, for the purpose of ascertaining whether these motions may not be ascribed to peculiarity of organization, aided by the operation of external causes. The plants selected for his experiments were, the Virginia Creeper, the Ivy, the Vine, and the Pea. When a young plant of the creeper, trained directly upwards, was placed alone in the centre of a forcing-house, its tendrils were all turned towards the north wall; but as this was out of their reach, they declined gradually, and ultimately fixed themselves on the upright stem beneath and upon its support.
