First Course In 



Zoology 



A NEW TEXT-BOOK FOR SECONDARY SCHOOLS, 

 NORMAL SCHOOLS, AND COLLEGES 



By T. W. Galloway, PH. D. 



Professor of Biology, James Millikin University, Decatur, Illinois. 

 With 240 Illustrations. Octavo; 460 pages. Cloth, $2.50 net. 



THE AUTHOR has endeavored in this book to present a balanced course 

 in Zoology which will be suitable to beginning classes in the last years of 

 the High School or the first year of College. It provides specifically 

 for class-room work, reference work in the library, laboratory work, and 

 field work. It includes a brief treatment of the fundamental principles of the 

 science in the first part of the book; the second part, which contains a discus- 

 sion of the great branches of the animal kingdom, is treated as a concrete 'illus- 

 tration of these general principles. 



Among many other distinctive excellences are seven features which give 

 the work especial merit: (i) It follows no fads; (2) Because of the wealth of 

 practical exercises suggested, it provides more work than any one class can 

 cover in the time allotted ; (3) Much collateral work in the library, field and 

 laboratory is outlined ; (4) The practical work is placed upon the broader 

 problems of physiology, of the relations of animals to the environment, and of 

 the adaptations of organic form to needs, rather than upon dissection and 

 minute anatomy; (5) The practical (i. e. the laboratory, field and library) work 

 is interspersed through the text in such a way as to illustrate and enforce the 

 more abstract definitions ; (6) Especial emphasis is put upon the illustrations; 

 (7) There are numerous analytical reviews and summaries.
