 junction into the stomach of the little one. As soon, how-

 support, and helped also to support the mother ; for by the 

 application of a lens, he saw that the red worm, for in-

 point of junction, and entered into the stomach of the 

 parent. Here the young have a lesson taught them, that 

 they should early learn habits of active usefulness, and that 

 they should seek to add to the comfort of their parents ; 

 but though this is taught, truth constrains us to confess 

 that the young polype does not always willingly practise the

 full equipment of tentacula, its body becomes attenuated at 

 the base, where it is joined to the older one, so that they are 

 connected only by a slender point, and by mutual consent 

 they seem disposed to part company. To effect this they 

 fasten themselves by their tentacula to diifcrent parts of the
