ANIMALS 



A TEXT-BOOK OF ZOOLOGY 



PUBLISHERS' NOTE 



THIS volume comprises Animal Life and Animal Forms, 

 each of which is designed for schools that assign but a half 

 year to Zoology. The two are issued in this form to meet 

 more satisfactorily the requirements of normal schools and 

 all higher schools that give a full year to the subject. It 

 is believed that it will be found a very desirable text, also, 

 for an elementary course in colleges. 



The prefaces of the two sections of the book explain 

 the plan, scope, and purpose of each. If preferred, the 

 second part of this volume, Animal Forms, treating the 

 morphological side of the subject, can be first taken up ; or 

 portions of each may be chosen and arranged in any order 

 that may best suit the teacher's purposes. The first part, 

 Animal Life, gives the ecological features of the subject 

 special prominence. 



Full indexes will be found at the end of each section.
