The assertion may then be made that the young tree assailed has beenstrangled or throttled by the creeper, but not that the latter has drained it of juicesand adapted them to its own use. Still less would the statement be applicable tothe numerous brown and red sea-weeds, which settle upon the ramifications of thegreat species of Sargassum, or of the innumerable Diatomaceae, which often entirely BACTERIA.

In still inlets of the sea it is not rare to seethe larger sea-wracks with smaller specimens clinging to them, whilst Floridese arefastened to the latter, and minute siliceous-coated diatoms to the Floridese.
