THIS work is designed to aid the student in getting a clear idea 

 of the animal kingdom as a whole, by the careful study of a few 

 typical animals. 



The student is first told how to collect and preserve the material for 

 his study. He is then given detailed directions for its examination 

 and dissection. It is not described for him, thus robbing him of the 

 opportunity to develop his own powers of description, but its parts are 

 named, giving barely enough of description that he may be sure to 

 recognize and apply the proper name to each. He is thus led to 

 observe and describe for himself. His attention is especially called 

 to some of the less obvious points, but explanations are seldom given 

 except when lack of time or ability renders it unlikely that he will prove 

 able to solve the problem unaided. 



All the animal sub-kingdoms are represented, more attention being 

 paid to those forms which the student is likely to find. He is led to 

 compare them, one with another, and by noting their resemblances and 

 differences he is shown how to classify animals, rather than taught a 

 system of classification. 



The work is limited to what can be done by the average high-school 

 pupil, as proved by the experience of several years during which these 

 guides to the study of animals have been in use. 



The following opinions are from those who have read 

 the tvorJc in manuscript or proof : — 



Alpheus Hyatt, Boston Society of 

 Natural History: The book is a very 

 fine thing. The author knows his sub- 

 ject. (Dec. 11, 1885.) 



David S. Jordan, Pres. Indiana 

 Univ. (author of "Synopsis of Fishes of 

 N. A.") : I have looked over the book 

 with much interest. It strikes me as 

 just the thing for teaching general zool- 

 ogy in high schools. I have long since 



given up zoological text-books as a bad 

 job, believing that no book which could 

 be used vjithout specimens had any value 

 to the student. This is just the book we 

 need for beginning zoological work in a 

 scientific spirit. I can promise you that 

 we shall adopt it here for beginning 

 classes, and think I shall not be dis- 

 appointed in it. It will be a great help 

 to me, as to many other teachers of 

 science.
