" The book deserves a warm welcome, and . . . will be found an 

 invaluable aid not only to students of zoology, but also to a large num- 

 ber of those whose main interest lies in other branches of scientific 

 study. Written with a clearness, accuracy, and method of a practised 

 teacher, it is admirably illustrated with a profusion of figures — there 

 are nearly twelve hundred in all — of the highest excellence."

"This work, the significance and usefulness of which must be un- 

 qualifiedly conceded, represents an enormous amount of labor upon 

 the part of two experienced teachers. Nor would we underrate the 

 admirable mechanical features of the work and the educational por- 

 tent of the issue of so large and costly a text-book upon a single 

 branch of natural history. The intent and method of the authors are 

 clearly set forth in the preface. After a general introduction and a 

 section upon ' General Structure and Physiology,' there are presented 

 in turn the twelve phylums recognized, viz. : Protozoa, Porifera, Ccelen- 

 terata, Platyhelminths, Nemathelminths, Trochelminths, Molluscoida, 

 Echinodermata, Annulata, Arthropoda, Mollusca, and (occupying the 

 whole of the second volume) Chordata, corresponding nearly with 

 Vertebrates. The discussion of each class is based upon a more or less 

 detailed account of the anatomy and development of one or more 

 forms, fairly representative and commonly available. The second 

 volume also contains a discussion of the mutual relationships of the 

 Chordata and of the twelve phyla. The last seventy pages are devoted 

 to Geographic Distribution, the Philosophy and History of Zoology, 

 and Modern Literature ; seven of the sixty writers recommended being 

 American." — The Nation.
