It is the purpose of this manual to include material that will intro- 

 duce the student to the subject of zoology. Therefore it includes sections 

 and appropriate exercises on general physiology, cytology, histology, 

 embryology, heredity, classification, and ecology, although it is devoted 

 in the main to a study of the structure of representative animals. In 

 this way it is hoped that the student will gain a clear idea of the mean- 

 ing and subject-matter of each of these branches of biology and their 

 relation to the general subject. 



The manual begins with an exhaustive study of the biology of the 

 frog, from which the student learns how a vertebrate animal is con- 

 structed, the function of each of its parts, and how these parts have 

 come into existence. With the knowledge thus gained he is in a posi- 

 tion to study other animals, which are taken up in their phylogenetic 

 order, beginning with the Protozoa, and including representatives of the 

 principal invertebrate phyla. In each case emphasis is laid upon the 

 comparison of the animal at hand with the frog. By means of this com- 

 parison the student is led to appreciate the simplicity of the organisms, 

 the order in which the functional systems of animals have arisen, and 

 the way in which these systems become specialized with increasing com- 

 plexity of structure. 



Directions throughout the manual are detailed and precise, thus enabling the 

 student to work by himself to the maximum degree. The purpose of each exercise 

 and its bearing upon the general subject are given, all terms are defined, and the 

 purpose and function of structures explained whenever possible. 



The matter of which the manual is composed was previously used for three 

 years in the Zoology Department of the University of Chicago and has met with the 

 approval of all who have seen it. The feature which has been particularly com- 

 mended is that each exercise has been described and explained in such a detailed 

 manner that much explanation and labor have been spared on the part of both 

 instructor and -student.
