sis broad; the leaf was then made to close. It was cut open 
after 45 hrs. The albumen was hard and compressed, with 
its angles only a little rounded; the gelatine was corroded into 
an oval form; and both were bathed in so much acid secretion 
that it dropped off the leaf. The digestive process apparently 
is rather slower than in Drosera, and this agrees with the length 
of time during which the leaves remain closed over digestible 
objects. 
Experiment 2.—A bit of aloumen =, of an inch square, but 
only 2; in thickness, and a piece of gelatine of the same size as 
before, were placed on a leaf, which eight days afterwards was 
cut open. The surface was bathed with slightly adhesive, very 
acid secretion, and the glands were all in an aggregated condi- 
tion. Not a vestige of the albumen or gelatine was left. Simi- 
larly sized pieces were placed at the same time on wet moss on 
the same pot, so that they were subjected to nearly similar con- 
ditions; after eight days these were brown, decayed, and matted 
with fibres of mould, but had not disappeared. 
Laperiment 3.—A piece of albumen 4, of an inch (3°81 mm.» 
long, and 3, broad and thick, and a piece of gelatine of the 
same size as before, were placed on another leaf, which was cut 
open after seven days; not a vestige of either substance was 
left, and only a moderate amount of secretion on the surface. 
Experiment 4.—Pieces of albumen and gelatine, of the same 
size as in the last experiment, were placed on a leaf, which 
spontaneously opened after twelve days, and here again not a 
vestige of either was left, and only a little secretion at one end 
of the midrib. 
Experiment 5.—Pieces of albumen and gelatine of the same 
size were placed on another leaf, which after twelve days was 
still firmly closed, but had begun to wither; it was cut open, 
and contained nothing except a vestige of brown matter where 
the albumen had lain. 
Experiment 6.—A cube of albumen of 4, of an inch and a 
piece of gelatine of the same size as before were placed on a 
leaf, which opened spontaneously after thirteen days. The 
albumen, which was twice as thick as in the latter experiments, 
was too large; for the glands in contact with it were injured 
and were dropping off; a film also of albumen of a brown 
colour, matted with mould, was left. All the gelatine was 
absorbed, and there was only a little acid secretion left on 
the midrib. 
Eaperiment 7.—A bit of half roasted meat (not measured) and 
a bit of gelatine were placed on the two ends of a leaf, which
