436 UTRICULARIA MONTANA. Cuar. XVIIL 
or less globular, or fine granules. In distant parts of the samo 
bladder, the processes were transparent and quite empty, with 
the exception of their solid nuclei. My son made at short 
intervals of time sketches of one of the above aggregated 
masses, aud found that they continually and completely changed 
their forms; sometimes separating from one another and again 
coalescing. Evidently protoplasm had been generated by the 
absorption of some element from the decaying animal matter. 
(2) Another bladder included a still smaller speck of decayed 
brown matter, and the adjoining quadrifids contained aggre- 
gated matter, exactly as in the last case. 
(8) 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, remind- 
ing 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 haying 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;
