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

No. of
Experi-
ment.		 Result.
  Heating effected by the application of the tips of heated forceps.
2 Heat applied to the axes close beyond a proximal leaf and far from the next
distal one. —Progressive centrifugal action along the whole course of axis. No
action below point of application.
3    Ditto    ditto    ditto.
4    Ditto    ditto    ditto.
5    Ditto    ditto    ditto.
6    Ditto    ditto    ditto.
7    Ditto    ditto    ditto.
8 Procedure as in the previous cases. —Results as in the previous cases save that the
primary pulvinus of the first leaf beneath the point of application acted.
9    Ditto    ditto    ditto.
10 Forceps applied nearer inferior than superior leaf. —Progressive complete action
of all the leaves above; no action below.
11 Application as in No. 10 .—Action in all the leaves above; no action below.
12    Ditto    ditto    ditto.
13 An old woody axis with three leaves with rigid primary pulvini above the point of
application of the forceps, which was immediately beyond the first inferior
leaf. —Action in the secondary pulvini and pinnules of the first leaf above; no
action below.
14 Procedure as in No. 10 .—Results as in No. 10.
15    Ditto ditto.
16 Forceps applied very close to the inferior leaf. —Action in the inferior leaf and in
all the distal ones.
17 Procedure as in No. 15. —Results as in No. 15.
18 Procedure as in No. 17. —Action in the first leaf above occurred 17 seconds after
application.
