INTRODUCTION 



TO THE STUDY OF 



ZOOLOGY. 



DIRECTIONS TO STUDENTS. 



The value of this work to you will depend largely 

 upon how much of it is done without assistance. You 

 are to acquire definite and exact information, of the 

 objects studied for the sake of learning how to acquire 

 definite and exact information of objects in general. 

 The solution of a problem in algebra is valuable not 

 for the information acquired in the answer, but for 

 the power acquired in learning how to find the 

 answer. 



The information about each specimen studied 

 should be obtained from the specimen itself as far as 

 such information can be thus obtained. It is a mis- 

 take to go to reference books, or to ask your neighbor 

 or your teacher, for information about the specimen 

 that the specimen itself can tell you. Some things 

 the specimen cannot tell. Under the head of "Addi- 

 tional Facts," this book states some of the things 

 about the animals studied which the specimens can- 

 not tell. After an animal form has been studied, it 

 is a good thing to read about it, but the reading should 

 follow and not precede the laboratory study.
