TIMES. — "There are very many, not only among educated people who take an 

 interest in science, but even among specialists, who will welcome a work of reasonable 

 compass and handy form containing a trustworthy treatment of the various departments 

 of Natural History by men who are familiar with, and competent to deal with, the latest 

 results of scientific research. Altogether, to judge from this first volume, the Cambridge 

 Natural History promises to fulfil all the expectations that its prospectus holds out." 



FIELD. — " We know of no book available to the general reader which affords such 

 a vast fund of information on the structure and habits of molluscs.'" 



KNOWLEDGE. — "If succeeding volumes are like this one, the Cambridge 

 Natural History will rank as one of the finest works on natural history ever published." 



ATHENyF.UiM. — "The series certainly ought not to be restricted in its circulation 

 to lecturers and students only ; and, if the forthcoming volumes reach the standard of 

 the one here under notice, the success of the enterprise should be assured."
