ZOOLOGY 



ORTON'S COMPARATIVE ZOOLOGY, STRUCTU- 

 RAL AND SYSTEMATIC 



Comparative Zoology, Structural and Systematic. For 

 use in Schools and Colleges. By James Orton, Ph.D. 

 New edition, revised by Charles Wright Dodge, M.S., 

 Professor of Biology in the University of Rochester. 

 With 350 Illustrations. Crown Svo, Cloth, $1 80 ; by 

 mail, $1 96. 



The distinctive character of this work consists in the treatment of 

 the whole Animal Kingdom as a unit ; in the comparative study of 

 the development and variations of organs and their functions, from 

 tlie simplest to the most complex state ; in withholding Systematic 

 Zoology until the student has mastered those structural affinities 

 upon which true classification is founded ; and in being fitted for 

 High Schools and Mixed Schools by its language and illustrations, 

 yet going far enough to constitute a complete grammar of the science 

 for the undergraduate course of any college. 



All unnecessary theoretical and debatable points are omitted. The 

 book is written in the light of the most recent phase of the science, 

 but not in the interest of any particular theory.
