80 LIFE BY THE SEASHOEE. 



knows them well, the very thought of Beroe, or medusoid, 

 brings back a vivid recollection of summer days spent idly 

 drifting over sunlit seas, when every rippling wave displays 

 new shapes of beauty, new gleams of rainbow colour. The 

 zoophytes similarly recall hours spent at the side of clear 

 rock pools, yielding every moment new charms to patient 

 search, new combinations of colour to the educated eye. 

 Even those to whom animals as a rule appeal but little 

 may be recommended to examine these sea-flowers, which 

 are to be found in every pool, and may be studied there in 

 all their beauty, without apparatus and without interference. 

 They are also especially suited to those who shrink from 

 comparative anatomy, as a rule, because it involves the 

 death of the object studied, for most of the Ccelentera can 

 only be properly investigated in the living condition, and 

 will yield many of their secrets to the unaided eye of a 

 patient observer. 



We have added to this chapter a table which may not 

 only assist in the naming of specimens, but also in enabling 

 the student to appreciate the number of different kinds of 

 animals included in the group Coelentera.
