Educational Psycholog;y 



By DANIEL STARCH, Ph.D., Associate Professor of Psy- 

 chology and Education in the University of Wisconsin. Cloth, 

 Crown Octavo, 473 pages. Published June 24th. 



"The aim of education is to change human beings for the better so that 

 they will have more humane and useful wants, and be more able to satify them." 

 In his new text-book, "Educational Psychology," Professor Starch uses th s de- 

 finition by Thorndike as his point of departure. He considers the fundamental 

 problems of educational psychology to be the determination of the capacities 

 which human beings possess for acquiring the changes, and the investigation and 

 evaluation of methods by which these changes may be brought about ; ac- 

 cordingly, he recognizes two large divisions in the field of educational psychology ; 

 first, the native equipment of human beings; secondly, the psychology of learn- 

 ing. The book treats these two major subdivisions separately; the first includes 

 considerations of the nature of human capacities, variation and inheritance of 

 mental traits, and measurement of mental equipment, the second deals with the 

 physiological and more strictly psychological aspects. An extensive third part 

 considers in detail the problems and practices of schools, and gives special atten- 

 tion to each of the subjects commonly taught.

Vertebrate Zoology 



By HORATIO H. NEWMAN, Ph.D., Associate Professor of 

 Zoology and Embryology, in the University of Chicago. Cloth, 

 Crown Octavo, about 545 pages, 220 illustrations. 



TABLE OF CONTENTS

This volume is intended for use as a text-book in college courses in verte- 

 brate zoology and comparative anatomy. Professor Newman approaches his 

 subject from the dynamic rather than the structural po nt of view; thus the 

 physiological, phylogenetic, ecological, and evolutionary aspects of vertebrates 

 are 'particularly emphasized; but careful attention is also given to anatomical 

 facts and data. 



The book is written in the light of the most recent advances in biology, 

 making use of important new conceptions and experimental evidence bearing 

 upon the evolution and comparative study of vertebrates.
