iv PREFACE 



4. A drawing in black and white has been 

 made of each example, and where it is 

 desirable to do so, the figures are arranged 

 so that one plate gives a comprehensive view 

 of its subject. 



5. A scale for measurement of the figures 

 has been furnished in those instances where 

 size is important. 



6. A list of books, useful in further study, 

 with the prices, has been added at the end 

 of each chapter. 



7. Practical instructions are given for col- 

 lecting and preserving the objects mentioned 

 in the book. 



Throughout I have sought to impress the 

 oft-forgotten fact, that a naturalist is not a 

 mere collector of specimens, but one who 

 loves Nature, and observes her methods and 

 operations. I have placed in an Introduction 

 some graver thoughts on the subject, which 

 might not appeal to all readers, and were on 

 that account less suited for the body of the 

 work, but which are too important to be 

 omitted in a book of this sort.
