 daced to eat meat, drawing it into the month with their tentacles, 

 and will generally take the little crab foand in the gilla of oysters, 

 which they consider an especial dainty, but 1 have never been able 

 to tempt the older ones with anything. They will not expand well

 of the tide-pools where they hide nnder the shadow of the rocks 

 and seaweed. If we try to handle them, as in taking them off the 

 rocks, they contract iato little solid lumps (Fig. 8), with app"^- 

 ently neither month nor tentacles. 



The children should examine them for several days, then brin^ 

 the results of their observations to the class, as was done with the

 a wheel in the cross-section given in Fig. 5, with the eggs
