304 UTRICULARIA MONTANA. (Cuar. XVIII. 
there were two masses of different sizes, one large and the 
other small; and in others there were irregularly shaped 
globules; so that it appeared as if the limpid contents of 
the processes, owing to the absorption of matter from the 
solution, had become aggregated sometimes round the 
nucleus, and sometimes into separate masses; and that 
these then tended to coalesce. The primordial utricle or 
protoplasm lining the processes was also thickened here and 
there into irregular and variously shaped specks of yellowish 
translucent matter, as occurred in the case of Utricularia 
neglecta under similar treatment. These specks apparently 
did not change their forms. 
The minute two-armed glands on the valve were also 
affected by the solution; for they now contained several, 
sometimes as many as six or eight, almost spherical masses 
of translucent matter, tinged with yellow, which slowly 
changed their forms and positions. Such masses were never 
observed in these glands in their ordinary state. We may 
therefore infer that they serve for absorption. Whenever a 
little water is expelled from a bladder containing animal 
remains (by the means formerly specified, more especially 
by the generation of bubbles of air), it will fill the cavity 
in which the valve lies; and thus the glands will be able 
to utilise decayed matter which otherwise would have been 
wasted. 
Finally, as numerous minute animals are captured by this 
lant in its native country and when cultivated, there can 
be no doubt that the bladders, though so small, are far from 
being in a rudimentary condition; on the contrary, they 
are highly efficient traps. Nor can there be any doubt that 
matter is absorbed from the decayed prey by the quadrifid 
and bifid processes, and that protoplasm is thus generated. 
What tempts animals of such diverse kinds to enter the 
cavity beneath the bowed antennz, and then force their 
way through the little slit-like orifice between the valve 
and collar into the bladders filled with water, I cannot 
conjecture. 
Tubers.—These organs, one of which is represented in a 
previous figure (fig. 26) of the natural size, deserve a few 
remarks. ‘Twenty were found on the rhizomes of a single 
plant, but they cannot be strictly counted ; for, besides the 
twenty, there were all possible gradations between a short 
length of a rhizome just perceptibly swollen and one so
