THE TRIUMPH OF LIFE 



animal. Both therefore do not grow as indi- 

 viduals alone, but they have formed a good co- 

 operative for production. 



From the swarms of jelly fish an individual 

 of especial beauty has separated itself. The 

 wish seizes us, in spite of its dangerous stinging 

 organs, to draw nearer to it in order to observe 

 it more closely. Strange, how does it happen to 

 continually avoid us.? Does it see us.'* To be

 It has also a small eye; but never did anyone

 transparent house, in the interior of the bell 

 swims a little fish, four and a half inches long, 

 like a gold fish in its glass. With its large ver- 

 tebrate eyes it sees us plainly through the trans-
