apt to throw off all the lovely diadems with which it is crowned, but that it will in process 

 of time supply the deficiency by new heads. Its reproduction is quite as remarkable as 

 that of any creature which has hitherto been mentioned, but of winch our failing space 

 will not permit a detailed account.

IN the Sertulariadse, the buds are inclosed in vesicles, and do not break away when 

 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 defies description. These little 

 polypes are wonderfully active and suspicious. At the least alarm, they retreat into theii 

 cells as if withdrawn by springs, and when they again push out their tentacles, it is in a 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 known 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 capabilities 

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



THE Campanularise, 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 spaco
