THE EIEST-TIDE POOL. 37 



between the flowers of the field and the flowers in 

 the garden. Those growing on a barren soil, removed 

 to a light rich earth, will expand into larger flowers 

 with brighter hues. Just so and more so with the sea- 

 weeds. There is one "pestilent fellow" — Ceramium 

 R-ubrum — who presents at one place the most deli- 

 cate ladylike appearance, quite a "lovely bit" in the 

 album, and at another place he is the coarsest, ugliest 

 of ragged rascals : we fling it away, and won't believe 

 that it is even related to the specimen we look for. 



Parasites on Fucus. 



"We have now observed and learnt the four species 

 of Fucus that cannot fail to attract our attention as 

 we walk between the tide-pools. In so doing we have 

 noticed the zoophyte Ilembranipora, and, doubtless, 

 those little white bristles which zigzag up the stem or 

 creep along the frond : they also are zoophytes — cities 

 of the SertuJaria. ■ Every notch on the bristle is the 

 home of one lovely little creature which, when in the 

 water, rises up, flinging forth twelve sensitive feelers, 

 that catch its food, and the whole bristle becomes a 

 spray of stars ; in daylight pearly white and flower- 

 like stars ; but at night every star flashes out phos- 

 phoric light, and the bristle is a wreath of illuminating 

 lamps to the living creatures of the great deep.
