muscles of jolly against the rush and might of 

 breaking waves. 



Even the individual comb-plates or rows of oars 

 are plainly seen, although, owing to their rapid 

 motion, they appear to the naked eye as a single 

 band of scintillating light. This and other magni- 

 fied photographs were obtained by fastening the 

 lens of a discarded bicvele lantern in a cone of 

 paper blackened on the inside with shoe-blacking. 

 AVith this crude apparatus placed in front of the 

 lens of the camera, the evanescent beauties of 

 these most delicate creatures were preserved. 



Other equally beautiful forms of jelly-fish are 

 balloon-shaped. These are Beroe^ fitly named 

 after the daughter of the old god Oceanus. They, 

 like others of their family, pulsate through the 

 water, sweeping gracefully along, borne on cur- 

 rents of their own making. 



Passing to other inhabitants of the pools, we 

 find starfish and sea-urchins everywhere abun- 

 dant. Hunched-up groups of the former show 

 where they are dining in their unique way on un- 

 fortunate sea-snails or anemones, protruding 

 their whole stomach and thus engulfing their vic- 

 tim. The urchins strain and stretch with their 

 innumerable sucker-feet, feeling for something to 

 grasp, and in this laborious way pull themselves 

 along. The mouth, with the five so-called teeth, 

 is a conspicuous feature, visible at the centre of 

 the urchin and surrounded by the greenish spines.
