Kellogg's Elements of Zoology. 



By Prof, Vernon L. Kellogg, Leland Stanford Universfty. 

 Seconii Edition, Revised. 484 pp. l2mo. %\.zo net. 

 A fully illustrated high-school text-book which provides for 

 work {a) in the laboratory, including the study of structure by 

 dissection and of physiology by observations of living specimens, 

 {b) in 'Cae. field, (c) and in the recitation or lecture room, discuss- 

 ing the significance, relations and general application of the 

 observed facts, and teaching the elements of classification and 

 distribution. 



Prof. E. A. Andrews, Johtis Hopkins: — I judge it one of the very few 

 good text-books in zoology yet produced. 



Louis Murbach, Detroit (Mich.) High School, in School Science :— In this 

 book a number of sound pedagogical ideas have been combined. It lays a 

 solid foundation beginning with the structure of some animal types. While 

 the laboratory directions are kept separate throughout the book, it is one of 

 the most successful in combining these with the text. 



Kellogg's First Lessons in Zoology. 



363 pp. l2mo. 

 Not an abridgment of the author's FAements of Zoology, but 

 an entirely independent work for high schools which do not under- 

 take dissections. The work is based on observation of animal 

 life and external structure. No detailed study of internal anatomy 

 is called for and no "laboratory" other than the schoolroom is 

 required. Animal activities and the life-history receive the em- 

 phasis. Structure is considered in connection with the use of 

 parts. The elements of animal physiology are so treated as to 

 afford a rational basis for the study of human physiology. On the 

 systematic or classificatory side the work is based on large like- 

 nesses and on habit and habitat rather than on details of structure. 



Hertwig's Manual of Zoology. 



Translated from the fifth German edition. By Prof. J. S. 

 KiNGSLEY, Tufts College. xi + 704pp. 8vo. %'i,.<x> net. 



For over ten years this has been the leading text-book on the 

 subject in Germany. The translation has been made with Amer- 

 ican conditions in mind, while many illustrations of American 

 forms have been added. 



Prof. C. 0. Whitman, University of Chicago .■— I am delighted to see this 

 Manual translated by- a competent naturalist. It is a most welcome and 

 important addition to the text-books now available. 



Prof. E. B. Wilson, Columbia :— The usefulness of Hertwig's book has 

 long been recognized, and Prof. Kingsley has introduced many improvements 

 that will commend themselves to American zoologists.
