In distant pa:·ts of the sa~e bbddcr, the processes were transpa~·c:mt 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 maRscs, and found that they continually and completely chang~d their forms; sometimes separating from one another and agam coaloBcing. Evidently protoplasm had bc~n ge~crated by the absorption of some clement from the. decaymg animn,l matter. (2) Another bladder included a still s~aller speck. of decayed brO\vn matter, and the adjoining quadn:fids contained aggre-gated matter, exactly as in the last case. . . · (3) A third bladder included a larger organis~, which. was so much decayed that I could only make out that It was spinose or hairy. The quadrifids in this case were not ~_uch affecto~, excepting that the nuclei in the several arms d1~ered mt~cJ: m size; some of them containing two n1asses havmg a similar a ppcarance. . . (4) A fourth bladder contained .an artiCu~ate_ . or.g~n1sm, for I distinctly saw the remnant of a hmb, tcrminatmg In a hook. The quadri:fids were not examined. (5) A fifth included much decayed matter apparently o~ s01~e animal, but with no recognisable features. The quadnfids m contact contained numerous spheres of prot~plasm. . (G) Some few bladders on the plant wh1ch I recmvcd from Kew were examined; and in one, there was a worm-s~a~od animal very little decayed, with a distinct remnant of a simtl~r one greatly decayed. Several of the arms of t~e processes. m contact with these remn.ins contained two sphcnca~ masses, hko the sinalc solid nucleus which is properly found In each ~rm. In another bladder there was a minute grain of quartz, rcmmdino · me of two similar cases with Utricularia neglectr1;. As it appeared probable that this plant would capture a greater number of animals in its native country ~han uncler culture, I obtained permission to remove s~n.ll portwns of ~~o rhizomes from dried specimens in the hcrbanum at Kew .. I d1cl not at first find out that it was advisable to soak the rhizomes for two or throe days, n.nd that it was necessary to open t~~ blaridcrs and spread out their contents o~ glass; as from the~r state of decay and from having been dr~e~ an~ pressed, th~Ir 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 ~hese mclucled remnants of animals. The first contained. a hauy Acarus, 8~ much decayed that nothing was left except Its transparei~t coat' CHAP. XVIII. ABSORPTION. 437 \ also a ycllo:V chitinous head of some animal with an int rnal fork, to ';hiCh the resophagus was suspended, but I could. , 00 no. mandibles; also the double hook of the tarsus of orne amma:; also an elongated greatly decayed animal; n.ncl la. tly, a cunous :fin.sk-shapccl organiRm, having the walls formed of rounde~ cells. ~ro.fessor Claus has looked at th'is latter organism, and t~Inks that It. Is the shell of a rhizopod, probably one of the Arcelhdm. I~ this bladder, as well as in several others, there were some uniCellular A1gm, and one multicellular AJrra which no doubt had lived as intruders. o ) A second blad ier contained an Acarus much le. s decaycJ. than the fo~mer one, wjth its eight legs preserved ; as well as remn~nts of several other articulate animals. A tl1ird bladder contained the ~nd of the abdomen with the two hinder limbs o~ a.n Acaru~, as I believe. A fourth contained remnants of a ~1stlnctly articulated bristly animal, and of several other organIsms, as well as much dark brown oro·n.nic mn.tter the nature of which could not be made out. 0 ' . So~e .blad~crs from a plan~, which had lived as an epiphyte In TrmHJad, In the West Indies, were ,next examined, but not so carefully as the others; nor had they been soaked lono· enough. Four of them contained much brown, trn.nslucent granular matter, apparently organic, but with no clisbnauishahle parts. The quadrifids in two were brownish, with 5 their contents granular; and it was evident that they had absorbed ~atter. In a fifth bl~dder there was a flask-shaped organism, hke that above mentiOned. A sixth contained a very lono· h d . bJ muc ecaycd, worm-shaped animal. Lastly, a seventh bladder contained an organism, but of what nature could not be distinguished. Only one experi1nent was tried on the quadrificl processes and glands with reference to their power of absorption. A bladder was punctured and l ft for 24 hrs. in a solution of one part of urea to 437 of water, and the quadrifid and bifid processes were found much affected. In some arms there was only a single symmetrical globular mass, larger than the proper nuclens, and consisting of yellowish matter, generally translucent but someti1nes granular; in others there were two n1asses of different sizes, one large and tho |
