Mimosa pudica —continued.

No. of
Experi-
ment.		 Result.
60 Leaf exposed to direct sunshine .—Complete action throughout the entire leaf; no
further result.
61 Ditto                     ditto                    ditto.
62 Slow, gradual action of the entire leaf; no further result.
63 Partial action in all the pinnæ; no further result.
64 Almost complete action throughout the entire leaf; no further result.
65 Partial action in all the pinnæ, and action of the primary pulvinus; no further result.
66 Almost complete action throughout the entire leaf; no further result.
67 Action in the cut pinnules; long pause; action in the primary pulvinus, but
depression of the petiole mechanically prevented; long pause; slow, partial,
centripetal action throughout the cut pinna; no further result.
68 Action in the cut pinnules, and in one or two pairs immediately beneath them;
long pause; action in the primary pulvinus; pause; centripetal action
throughout the cut pinna; partial action in the remaining pinnæ; no further
result.
69 Leaf in the shade .—Action in the cut pinnules; long pause; action in the primary
pulvinus, but depression of the petiole mechanically obstructed; very slight
action in two or three pairs of pinnules beneath the cut ones; no further
result.
70 Leaf exposed to direct sunshine .—Partial action throughout the entire leaf save the
proximal pinna of the uncut side; no further result.
71 Leaf exposed to direct sunshine .—Slow, complete action throughout the entire
leaf; no further result.
72 Leaf in shade ,—Spreading, incomplete action in all the pinnules of the cut pinna;
incomplete action in the basal halves of two other pinnæ; no further result;
primary pulvinus responded readily to direct impulse.
73 Leaf in shade .—Incomplete action throughout the distal half of the cut pinna; no
further result.
74 Leaf in shade .—Incomplete action throughout the cut pinna; no further result.
75 Leaf exposed to direct sunshine .—Complete action in the leaf; no further result.
