TABLE X.—Results Application of Heat to the axes of Mimosa pudica
—continued.

No. of Experi- ment.	Result.
33	Application as in No. 29, the points of the forceps almost touching the pulvinus of the leaf next below.— Slow action in first two leaves above; no action below.
34	Application as in No. 29. —Very long pause; action in the primary pulvinus of leaf next above; very long pause; commencing action in the pinnæ of the first leaf, and action in primary pulvinus of the next leaf above; pause; action in the pinna of the second leaf; no action below.
35	Application as in No. 29. —Long pause; action of leaf next above; very long pause; action in terminal leaf of axis separated by six internodes from the previous leaf; action in the leaf below the terminal one; pause; action in leaf above that one which acted first; no further action.
36	Application as in No. 29. —Pause; action in leaf next above; short pause; action in leaf next below; very long pause; action in primary pulvinus of second leaf above site of application; long pause; action in its pinnæ; no further result.
37	Forceps very strongly heated. —Almost. immediate action in leaf next below; long pause; action in primary pulvinus of first leaf above; pause; progressive, cen- trifugal action in its pinnæ; very long pause; action of the third leaf above the site of application; partial and slow action in pinnæ of the second leaf above the site of application; no further result.
38	Application as in No. 29. —Action in leaf next above; action in leaf next below; ac- tion of the second leaf beneath that (the intermediate leaf was at a rooted node); action in the first leaf of the axillary shoot of the leaf above the point of appli- cation; no action in the second leaf above, which was situated at a rooted node.
39	Application as in No. 29. —Action in all the leaves above the point of application; no action below.
40	Application as in No. 29. —Action in fourteen leaves on axis and shoots above, the primary pulvini alone acting in the more distal ones; no action below.
41	Application immediately above the inferior leaf. —Slow, progressive, centrifugal action in the primary pulvini of all the leaves above; the secondary pulvini and pinnules only acted in some cases, and in these after long intervals; no action below.
42	In this experiment the flame of a wax match was applied direct to the axis. —Ac- tion in four leaves above; no action in the fifth and terminal one; no action below.
