flected, or plainly sub-inflected. After 4 hrs. the tentacles 
began to re-expand, and such prompt re-expansion is unusual ; 
after 7 hrs. 30 m. they were almost fully re-expanded. 
(2) After 89 m.a large number of tentacles inflected ; after 
2 hrs. 18 m. all but twenty-five inflected; after 4 hrs. 17 m. all 
but sixteen inflected. The leaf remained in this state for many 
hours. 
(8) After 12 m. a considerable amount of inflection; after 
4 hrs. all the tentacles inflected except those of the two outer 
rows, and the leaf remained in this state for some time; after 
23 hrs. began to re-expand. 
(4) After 40 m. much inflection ; after 4 hrs. 13 m. fully half 
the tentacles inflected; after 23 hrs. still slightly inflected. 
(5) After 40 m. much inflection; after 4 hrs. 22 m, fully half 
the tentacles inflected ; after 23 hrs. still slightly inflected. 
(6) After 40 m. some inflection; after 2 hrs. 18 m. about 
twenty-eight outer tentacles inflected ; after 5 hrs. 20 m. about a 
third of the tentacles inflected ; after 8 hrs. much re-expanded. 
(7) After 20 m. some inflection; after 2 hrs. a considerable 
number of tentacles inflected; after 7 hrs. 45 m. began to 
re-expand., 
(8) After 38 m. twenty-eight tentacles inflected; after 3 hrs. 
45 mm. thirty-three inflected, with most of the submarginal 
tentacles sub-inflected ; continued so for two days, and then 
partially re-expanded. 
(9) After 38 m. forty-two tentacles inflected; after 3 hrs. 
12 m. sixty-six inflected or sub-inflected ; after 6 hrs. 40 m. all 
but twenty-four inflected or sub-inflected ; after 9 hrs. 40 m. all 
but seventeen inflected; after 24 hrs. all but four inflected or 
sub-inflected, only a few being closely inflected ; after 27 hrs, 
40 m. the blade inflected. The leaf remained in this state for 
two days, and then began to re-expand. 
(10) After 38 m. twenty-one tentacles inflected; after 3 hrs. 
12 m. forty-six tentacles inflected or sub-inflected ; after 6 hrs. 
40 m. all but seventeen inflected, though none closely; after 
24 hrs. every tentacle slightly curved inwards : after 27 hrs. 
40 m. blade strongly inflected, and so continued for two days, 
and then the tentacles and blade very slowly re-expanded. 
(11) This fine dark red and rather old leaf, though not very 
large, bore an extraordinary number of tentacles (viz. 252), and 
behaved in an anomalous manner. After 6 hrs. 40 m. only the 
short tentacles round the outer part of the disc were inflected, 
forming a ring, as so often occurs in from 8 to 24 hrs. with 
leaves both in water and the weaker solutions. But after 9 hra
