TABLE I.—General Table of Results of section of Distal Pinnules of
Mimosa pudica—continued .

No. of
Experi-
ment.		 Result.
33 Leaf not yet reached by the sunshine .—Action of two or three pairs of pinnules;
action in primary pulvinus; slow, partial, centripetal action in the cut pinna;
slow, centrifugal action in the rest of the pinnæ; no further result.
34 Leaf in shade .—Very slow, complete, centripetal action in the cut pinna; action in
the primary pulvinus when the action in the cut pinna had almost reached the
base; very slow, partial action in the other pinnæ; no further result.
35 Leaf exposed to direct sunshine .—Complete, spreading action in the cut leaf;
partial action in one beneath; complete action in the first leaf above; action
in the primary pulvinus of the third leaf above; very slow, partial action in its
pinnæ; no further results.
36 Leaf exposed to direct sunshine .—Complete, spreading action in the cut leaf; no
further result.
37 Leaf exposed to direct sunshine .—Result as in the previous case.
38 Ditto                    Ditto.
39 Ditto                   Ditto.
40 Leaf in shade .—Partial action in the cut pinna; slight action in the primary
pulvinus; no further result.
41 Leaf in shade .—Action in the distal two-thirds of the cut pinna; no further
result.
42 Leaf in shade .—Action in the cut pinnules; action in the primary pulvinus; slow,
progressive, centripetal action in the pinnules in the distal third of the cut
pinna; no further result.
43 Leaf in shade .—Slow, progressive, complete action in the cut pinna; no further
result.
43 Leaf in shade .—Complete, progressive action in the cut pinna; long pause;
action in the primary pulvinus; no further result.
44 Leaf in shade .—Action in the cut pinna; action in the primary pulvinus, and
extreme depression; partial action in the remaining pinnæ; no further
result.
45 Leaf in shade .—Action in the cut pinna; action in the primary pulvinus; no
further result.
