 of the economical, physiological, and systematical relations of molluscous 

 animals to each other and to other created beings ; and this he has done in a

 trating his theories by learned references and curious anecdotes, that it is 

 not easy to decide whether his work is most valuable as a scientific, or 

 interesting as a literary composition." Morning Post.
