Cuar. XIIL.] DIGESTION, 245 
spontaneously after eleven days; a vestige of the meat was left, and 
the surface of the leaf was here blackened ; the gelatine had all dis- 
appeared. 
Lxperiment 8—A bit of half roasted meat (not measured) was 
placed on a leaf which was forcibly kept open by a clip, so that it was 
moistened with the secretion (very acid) only on its lower surface. 
Nevertheless, after only 223 hrs. it was surprisingly softened, when 
compared with another bit of the same meat which had been kept 
damp. 
Experiment 9—A cube of yy of an inch of very compact roasted 
beef was placed on a leaf, which opened spontaneously after twelve 
days; so much feebly acid secretion was left on the leaf that it trickled 
off. The meat was completely disintegrated, but not all dissolved ; 
there wasno mould. ‘The little mass was placed under the microscope ; 
some of the fibrilla in the middle still exhibited transverse striz ; 
others showed nut a vestige of striae; and every gradation could be 
traced between these two states. Globules, apparently of fat, and some 
undigested fibro-elastic tissue remained. The meat was thus in the 
same state as that formerly described, which was half digested by 
Drosera. Here, again, as in the case of albumen, the digestive process 
seems slower than in Drosera. At the opposite end of the same leaf, a 
firmly compressed pellet of bread had been placed; this was completely 
disintegrated, I suppose, owing to the digestion of the gluten, but 
seemed very little reduced in bulk. 
Experiment 10.—A cube of jy of an inch of checse and another of 
albumen were placed at opposite ends of the same leaf. After nine 
days the lobes opened spontaneously a little at the end enclosing the 
cheese, but hardly any or none was dissolved, though it was softened 
and surrounded by secretion. Two days subsequently the end with 
the albumen also opened spontaneously (¢.e. eleven days after it was 
put on), a mere trace in the blackened and dry condition being left. 
Experiment 11.—The same experiment with cheese and albumen 
repeated on another and rather torpid leaf. ‘lhe lobes at the end with 
the cheese, after an interval of six days, opened spontaneously a little ; 
the cube of cheese was much softened, but not dissolved, and but little, 
if at all reduced in size. Twelve hours afterwards the end with the 
albumen opened, which now consisted of a large drop of transparent, 
not acid, viscid fluid. 
Experiment 12.—Same experiment as the two last, and here 
again the leaf at the end enclosing the cheese opened before the oy:po- 
site end with the albumen; but no further observations were made. 
Experiment 13.—A globule of chemically prepared casein, about 75 
of an inch in diameter, was placed on a leaf, which spontaneously 
opened after eight days, The casein now consisted of a soft sticky 
mass, very little, if at all, reduced in size, but bathed in acid secretion. 
These experiments are sufficient to show that the secretion 
from the glands of Dionza disso:ves albumen, gelatine, and
