HARDWICKE'S SCIENCE-GOSSIP. 



I remember that the first time I met with it, it presented the 



appearance shown, and for hours obstinately refused to unfold 

 its corona. Dr. Hudson, with his usual kindness, identified the 

 specimen for me. I think a reference to Hudson & Gosse's 

 ' Rotifcra ' would also have enabled Mr. W. S. Smith to have 

 identified his cuiious animalcule as a furcularia."
