THE GLANDS OF BYBLIS GIGANTEA. II 
Experiment III. 
A cube of albumen (about 2°5 mm. in length), slightly 
larger than that used in Experiment II., was placed on 
the sessile glands. After twenty-four hours a little 
secretion had been poured out, which after forty-eight 
hours was very much increased. On examining the cube 
at the end of the fourth day, it was found that the lower 
edges and corners had been rounded off. After six days 
the cube had sunk down on to the surface of the leaf, and 
the upper edges and angles were rounded off. Two days 
later the cube had become more or less round. At the 
close of the eleventh day the remains of the cube were 
found lying on the surface of the leaf quite dry, the whole 
of the secretion having been absorbed. 
Experiment IV. 
A small cube of albumen just under I mm. in size, 
which had just been removed from an egg, and thus was 
moist, was placed on the sessile glands, and after two days 
had been completely dissolved. _ 
Experiment V. 
A cube of albumen of a little over 1 mm. in size was 
cut from the top of an egg which had been kept for about 
two days. This cube was carefully dried so as to remove 
all traces of moisture and was then placed on the sessile 
glands so that it did not come into contact with the 
secretion from the stalked glands. This cube was 
examined at the end of the first, second, third, fourth, and 
fifth days, and after this time, examination with a lens 
showed that the edges and angles had not been rounded 
off, and it was not surrounded by a drop of secretion. 
Experiment VI. 
Small fragments of broken glass were placed on the 
sessile glands which were observed every day for a week ; 
by the end of the period no secretion had been poured out.
