 Hornwrack. 



A few of the translucent Medusae, in a young 

 stage of their existence, might be procured and 

 tried, though their transport would be difficult ; and 

 a group of creatures, of the genus Zoofhamnium^ 

 forming, as they do, an object like a little tree of 

 glass, covered with trumpet-shaped bells, of the 

 same crystalline aspect, each exhibiting its rotating 

 circle of minute cilia in rapid motion within, would 

 form a singular and beautiful complement to the 

 wonders of the Aquarium, if its removal from its 

 native depths, and its location in its new home, 

 could be successfully managed.
