THE ANIMAL MIND 



A Text-Book of Comparative Psychology. By Margaret Floy

"It is the first objective account founded upon years of 

 patient research and upon discerning and expert analyses. For 

 the first time it renders accessible to the studious lajmien in 

 readable form the kind of data, the critical interpretation 

 of results, and the source of the guiding principles that in the 

 modern view are likely to bring some systematic understand- 

 ing of animal psychology." Condensed from a long review in 

 The Dial, Chicago.

Lectures on Human and Animal Psychology 



By Wilhelm Wundt. Translated from the Second German 

 Edition by J. E. Creighton and E. B. Titchener. 



In this later edition of an early work Professor Wundt 

 has eliminated everything not pertaining to the individual 

 psychology of man and the animals, and has confined himself to 

 the treatment of topics which he considers especially character- 

 istic of the spirit and trend of modern psychology. The trans- 

 lators have put this work before the English-speaking public 

 with the hope that its comparatively popular and introductory 

 character will render it acceptable to those beginning the study 

 of psychology, and to others who desire some knowledge of the 

 methods and results of the new psychological movement.
