IN the Sertulariadas, the buds are inclosed in vesicles, and do not break away wheii 

 adult. They are placed in cup-like cells, which have no footstalks. 



Any of the common Sertulariae affords a good example of this family ; and as they 

 are easily procured, they are very valuable aids to those who wish to study the structure 

 of these beautiful beings. Even the empty polypidon is not without its elegance, and 

 is often made up into those flattened bouquets of so called sea-weeds, which are sold 

 in such quantities at sea-side bathing towns. But when the whole being is full of 

 life and health, its multitudinous cells filled with the delicate polypes, each furnished 

 with more than twenty tentacles all moving in the water, its beauty deiles description. 

 These little polypes are wonderfully active and suspicious. At the least alarm, they 

 retreat into their cells as if withdrawn by springs, and when they again push out their 

 tentacles, it is in a very wary and careful manner. 



The reproduction of these beings is very curious, for it is ki.own that they can be 

 propagated by cuttings just like plants, as well as by cell vesicles, and that in the latter 

 case the first stage of the young closely resembles that of the young medusae already 

 mentioned. They also reproduce by offshoots ; and it is very likely that their capa- 

 bilities in this respect are not limited even to these three methods. 



THE Campanularia;, or Bell- zoophytes, may be distinguished from the last family by 

 having the cells placed on footstalks. Two figures of the BELL-ZOOPHYTE are given, in 

 order to show it as it appears of the natural size, and as it looks when magnified. 



The whole history of this creature is very interesting, but on account of failing space
