On the Electromotive Properties of the Leaf of Dionaea in the Excited and Unexcited StatesSecond Paper . The observation was so arranged, that the opposite surfaces of either lobe could beconnected with the galvanometer. As usual, these were found in very different con-ditions, but in both the direction of the difference was {, and in both the excitatoryresponses were those seen in unmodified leaves. The galvanometer circuit was soarranged that it could be connected symmetrically either (1) with the two undersurfaces or (2) with the two upper ones, that is, with the two spaces between the hair
On the Electromotive Properties of the Leaf of Dionaea in the Excited and Unexcited StatesSecond Paper . The observation was so arranged, that the opposite surfaces of either lobe could beconnected with the galvanometer. As usual, these were found in very different con-ditions, but in both the direction of the difference was {, and in both the excitatoryresponses were those seen in unmodified leaves. The galvanometer circuit was soarranged that it could be connected symmetrically either (1) with the two undersurfaces or (2) with the two upper ones, that is, with the two spaces between the hairson opposite sides. The condition of the leaf was carefully observed, and it was foundthat the state of things was, an hour or two after the leaf had been prepared, asrepresented by diagram 7. The upper surface of each lobe was positive to the under,but the difference was much greater on the right side than on the left, and the rightunder surface was positive to the left under surface. The current of a single Daniellscell was now led for 10 seconds through the right lobe from m to/, and the processr
