14 Commencing centrifugal action in that pinna; action in the primary pulvinus;
completed action in the cut pinna extending nearly to the tip; long pause.
centrifugal action almost to the tip of the remaining pinna (a two-pinnaed leaf).
15 Pause; action in that and the opposite secondary pulvinus; slow, spreading
action in the bases of both proximal pinnæ; pause slight action in the bases
of both distal pinnæ; no further result; primary pulvinus rigid.
16 Long pause; slow, centrifugal action in the base of that pinna; pause; action
extended almost to the tip; slow action in the basal half of the remaining
pinna (a two-pinnaed leaf); no further result; primary pulvinus readily
responsive to mechanical impulse.
17 Pause; very slow, imperfect action in the basal two-thirds of both pinnæ (a two-
pinnaed leaf); no further result; primary pulvinus rigid.
18 Pause; slow, centrifugal action in that and the other proximal pinna; pause
action in the primary pulvinus; slow, partial action in the other two pinnæ.
19 Slow, partial, imperfect action in that pinna; action in the primary pulvinus;
slow, partial action in the remaining pinnæ.
20 Action in the primary pulvinus; imperfect action in that pinna; long pause; partial
action in the basal two-thirds of the other pinnæ.
  C.—Section of tips of central pinnules of proximal pinnæ .
21 Pause; imperfect centripetal action in that pinna; pause; very imperfect centri-
fugal action in it; no further result; the primary pulvinus readily responsive
to mechanical impulse.
22 Pause; centripetal action in that pinna; very imperfect centrifugal action in it;
very slow, imperfect action in the basal halves of the remaining pinnæ; no
further result; primary pulvinus readily responsive to mechanical impulse.
23 Pause; imperfect centripetal action; pause; very slow, imperfect centrifugal
action; action in the primary pulvinus; imperfect action in the remaining
pinnæ; no further result.
24 Pause; centripetal action in that pinna; centrifugal action in it; action in the
primary pulvinus; incomplete action in the other pinnæ; no further result.
25 Action in the primary pulvinus; centripetal action in the cut pinna; very slow,
centrifugal action in it; imperfect action in the other pinnæ; no further
result.
