FIELD. — " The Cambridge Natural History series of volumes is one of 

 very great value to all students of biological science. The books are not 

 intended for jaopular reading, but for utilisation by those who are desirous 

 of making themselves thoroughly acquainted with the branches of zoology of 

 which they treat."

CAMBRIDGE REVIEW. — ''Wo^t of the articles are of a very high order of 

 merit — taken as a wliole, it may be said that they are by far the best which have 

 as yet been published. . . . We may say with confidence that the same amount of 

 inlormation, within the same compass, is to be had in no other zoological woik."

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 depart- 

 ments of Natm-al History by men who are familiar with, and comiietent 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 

 prosj)eetus holds out."
