(2) Another bladder included a still smaller speck of decayed brown
matter, and the adjoining quadrifids contained aggregated matter,
exactly as in the last case.
(3) A third bladder included a larger organism, which was so much
decayed that I could only make out that it was spinose or hairy. The
quadrifids in this case were not much affected, excepting that the
nuclei in the several arms differed much in size; some of them
containing two masses having a similar appearance.
(4) A fourth bladder contained an articulate organism, for I distinctly
saw the remnant of a limb, terminating in a hook. The quadrifids were
not examined.
(5) A fifth included much decayed matter apparently of some animal, but
with no recognisable features. The quadrifids in contact contained
numerous spheres of protoplasm.
(6) Some few bladders on the plant which I received from Kew were
examined; and in one, there was a worm-shaped animal very little
decayed, with a distinct remnant of a similar one greatly decayed.
Several of the arms of the processes in contact with these remains
contained two spherical masses, like the single solid nucleus which is
properly found in each arm. In another bladder there was a minute grain
of quartz, reminding me of two similar cases with Utricularia neglecta.
As it appeared probable that this plant would capture a greater number
of animals in its native country than under culture, I obtained
permission to remove small portions of the rhizomes from dried
specimens in the herbarium at Kew. I did not at first find out that it
was advisable to soak the rhizomes for two or three days, and that it
was necessary to open the bladders and spread out their contents on
glass; as from their state of decay and from having been dried and
pressed, their nature could not otherwise be well distinguished.
Several bladders on a plant which had grown in black earth in New
Granada were first examined; and four of these included remnants of
animals. The first contained a hairy Acarus, so much decayed that
nothing was left except its transparent coat; [page 437] also a yellow
chitinous head of some animal with an internal fork, to which the
oesophagus was suspended, but I could see no mandibles; also the double
