TABLE IX.—Results attending Mechanical Obstruction to the depression of
the Petiole o n action of the Primary Pulvinus— concluded.
| No. of Experi- ment. |
Result. |
| 16 | Slow, progressive, almost complete action in that pinna; full depression; action in basal half of the next pinna; no further result. |
| 17 | Slow, progressive action in that pinna; full depression; no further result. |
| 18 | Slow, progressive action in that pinna; pause; extreme depression; gradual, complete centrifugal action in the other pinnæ. |
| 19 | Slow, progressive action in that pinna; pause; full depression; almost complete, centrifugal action in the basal two-thirds of the other pinna. |
| 20 | Slow progressive, complete centripetal action in that pinna; pause; full depres- sion; pause; slow, centrifugal action in basal halves of two other pinnæ. |
| 21 | Slow, progressive, complete action in that pinna; pause; extreme depression slow, centrifugal action in the basal two-thirds of the other pinnæ. |
| 22 | Ditto ditto ditto. |
| 23 | Slow, progressive, centripetal action in that pinna; pause; full depression; action in basal halves of the other pinnæ. |
| 24 | Ditto ditto ditto. |
In the above table we have the results of twenty-four experiments conduct-
ed on the same morning on leaves under precisely similar circumstances save
that in twelve of the cases depression of the petiole was mechanically obstructed
or prevented, whereas in the remaining twelve it was fully carried out. In three
of the first set action was manifested in other pinnæ than the cut one in ten
of the second set a similar phenomenon was present.
TABLE X.—Results of Application of Heat to the axes of Mimosa pudica.
| No. of Experi- ment. |
Result. |
| 1 | Heating effected by means of coiling one extremity of a piece of copper wire round the axes and applying a spirit-lamp flame to the free extremity.— Centrifugal action of all the leaves above the point of application; no action below. |
