 labour. . -.. 



" Some idea of the gigantic results of this division 

 of labour may be formed, if I tell you that large Islands? 

 are formed by the labours of certain kinds of sting> 

 ing Zoophyte known as Corals. Not to go far, the 

 Maldive and Laccadive Archipelagoes are good exampl.es> 

 of such Coral Islands. You want to know how they 

 were formed. It is simple enough. In ages past mil- 

 lions upon millions of Corals gave rise by budding and

 in shallower waters formed vast reefs : so vast that they 

 ultimately became raised to the level of the sea and 

 laid the foundation as it were, of the present groups of 

 Islands." 



WORM TO MAN. 



"We now come to altogether a different series of> 

 animals, which are as interesting as those we have 

 hitherto examined. In the latter we did not find. any ; . 

 trace of a posterior or tail end properly so called. Nox 

 by any stretch of imagination could the body of any 

 of those animals be said to possess ventral or dorsal 

 aspects ; that is, a lower surface turned, towards the, 

 ground, and upon which the animal moves, and an , 

 upper or back surface. The animals of the present , 

 series seem, however, to have been constructed upon a, ; 

 different plan, as, in the majority of them at least, we ; 

 can distinguish a head and a tail, and also an upper
