1. The incipient contraction of a growing organ under stimulus culminates in a marked shortening of the organ.
2. The similarity of contractile responses in growing and pulvinated organs.
3. Similar modification of both under condition of sub-tonicity.
4. The opposite effects of Direct and Indirect stimulus, both in motile and in growing organs.
5. The exhibition by all plant-organs of negative electric response under Direct, and positive electric response under Indirect stimulus.
6. Similar modification of autonomous activity in Desmodium gyrans and in growing organs under parallel conditions.
7. Similar excitatory effects of various stimuli on pulvinated and growing organs.
8. Similar discriminative effects of different rays of light in excitation of motile and growing organs.
