TABLE VI.—General Table of Results of Application of Heat to the tips of
Distal Pinnules —concluded.

No. of
Experi-
ment.		 Result.
30 Results as: in No. 28.
31 Spreading action in the pinnules of that pinna; pause; action in the secondary
pulvinus of the affected pinna and in that of the distal pinna of the same side;
commencing action in the pinnules of the latter pinna, and action in the
primary pulvinus; action in the other pinnæ.
32 Spreading action in the pinnules of that pinna; action in its secondary pulvinus
and in that of the distal pinna of the same side of the leaf; commencing action
in the pinnules of that distal pinna, and action in the primary pulvinus; pause;
action in the remaining pinnules of the first distal pinna, and action in the other
pinnæ; action in one leaf next above.
33 Spreading action in that pinna; action in the remaining pinnæ successively from
the injured side of the leaf to the other; no action in the primary pulvinus.
34 Spreading action in that pinna; action in all the secondary pulvini and in the pri-
mary one; action in the pinnules of the remaining pinnæ.
35 Slow and irregular action in that pinna; no further result.
36 Spreading action in that pinna; pause; action in that secondary-pulvinus; action
in the primary pulvinus, and commencing action in the distal pinna of that side;
pause; action in the other pinnæ.
37 Spreading action in the pinnules; action in the secondary pulvinus of that pinna
and in the primary pulvinus; pause; action in the remaining pinnæ.
38 Slow, spreading action in that pinna; action in its secondary pulvinus; action in
the primary pulvinus; pause; slow, centrifugal action in the remaining pinnæ.
39 Results similar to those in No. 38 save that the secondary pulvinus acted before the
basal pinnules.
40 Results similar to those in No. 38 save that the basal pinnules of the distal pinna of
the same side of the leaf had begun to act before the primary pulvinus did so.

     A total of 40 experiments, in only 6 of which was there any extension of
movement beyond the primarily affected leaf.
