In this class we believe there will be exhibited a fine collection 

 of sponges from Greece, and some remarkable Italian corals ; 

 while we are given to understand that both the Mollusca and 

 Crustacea will be well represented by carefully selected and well- 

 arranged specimens. 



The Naples correspondent of the ' Daily News ' informs us 

 that one of the most notable features in this Class will be a 

 collection of marine animals contained in 350 glass jars, and 

 forwarded by Dr. Dohrn, Director of the Naples Zoological 

 Station. This collection (which up to the moment of writing 

 had not arrived) is thus described : — 



" By new methods adopted in preservation the most delicate organisms 

 are immortalised in spirit, with little or no loss of their original beauty of 

 form. In one bottle you see a small, indistinguishable lump of animal 

 substance, which is, or rather was, a pretty Alcycnium, or Cork-polype; in 

 another, the same animal fully expanded in all its delicate transparency, 

 and covered with the little polypes that look like tiny flowers. In another 

 receptacle you see a kind of shrunken soft tube with a few tentacles hanging 

 out of it that look like wet feathers; it is a Pennatvla, or Sea-feather. 

 These and other animals are so sensitive when alive, that if the water of 

 the tank in which they live be merely shaken, or in some cases if only a 

 cloud darkens the light, they at once shrink up. The method adopted to
