The larger rings in the figure representmoats floating with the sap. 88. The polypi not only resemble plants in their ex-ternal appearance, after the manner of the zoanthus oranimal flower (81), but they even multiply by buds, likea tree. These buds are called gemmules. They soonfall ofl^, and commence an independent existence. Theyare provided, from the first, with moving cilia, whichcarry them oflT in search of a proper place of perma-nent residence, the moment they are detached from theparent. In fig. 15, you see a figure of the gemmule ofa flustra, covered with its cilia. Even those polypi which remain fixed for life in one spot,have thus the power of transporting their raceto a distance, by means of a locomotive powerwhich the young lose for ever the moment thatthey select their station: but they make thisse
