tre.This is how the creature obtains itsfood. Along the arms forming thefronds are little finger-like projectionson each side and these are coveredwith minute hairs (cilia). The cilia canbe seen only with a high-power micro-scope; they beat in unison and it is their combined action that causes thecurrent. But even with a hand lens,the little fingers can be seen bendingdown to help push a choice particletowards the mouth or, if an unsuit-able bit arrives, the fingers help toreject it and push it aside. The wholesystem of fronds, finger projectionsand cilia forms an elaborate net toguide food to the mouth of theanimal. The action of these creaturesspreading their nets to catch foodnever fails to arouse interest. If it ispossible to see them with a low-powerstereo-microscope, the three dimen-sional view makes things even moreinteresting. With the fronds extended, we nolonger see the operculum for it hasdisappeared behind them, but we stilldo not know what kind of animal weare looking at.

Wormremoved from limy tube.Galeolaria caespitosa.(From Linnean Soc. 1884.) November/December 229 The animal out of its tube The next step is to select one tubeand gently break it apart withoutdamaging the inhabitant. Sometimes,merely breaking the whole sample inhalf will do the trick and will releasea tube dweller. We place the freed animal in asmall saucer or petrie dish and, withlight from a desk lamp, we can havea good look with the stereo-microscope or hand lens. What wenow see is shown in Fig. 4. (For agood drawing it was necessary to goto the Proceedings of the LinneanSociety 1884.) What we now see is aworm (1) of some sort, about 15-25mm in total length. An initial exami-nation shows that it is composed ofmany segments (2). The operculum is at the end of ashort pillar called the peduncle grow-ing out from the dorsal side of theworm. The frond arms
