living substance emerges from the chalky plates, 

 and after a while puts forth a number of ten-

 proximate cause of its death appeared to be

 (Actinia hellis), which lived in a cave like a

 am accustomed to stir the water daily, in order 

 to imitate as far as possible the natural stir of 

 the sea, and in so doing this madrepore was 

 washed into the cave where resided the daisy

 its own little home, which had been specially 

 chiselled in the rock, it never properly recovered ;
