THE AMERICAN SCIENCE SERIES. 5 



ZOOLOGY Continued. 

 Elementary Course. (In press.} 



In general method this book is the same with those just de- 

 scribed, but, being meant for quite young pupils, it gives more 

 attention to the higher organisms, and to such particulars as 

 can be studied with the naked eye. In everything the aim has 

 been to make clear the cardinal principles of animal life, rather 

 than to fill the pupil's mind with a mass of what may appear to 

 him unrelated facts.

Aims to lead the student to obtain at first-hand his knowl- 

 edge of the anatomy and physiology of plants. Accordingly, 

 the presentation of matter is such as to fit the book for con- 

 stant use in the laboratory, the text supplying the outline sketch 

 which the student is to fill in by the aid of scalpel and micro- 

 scope. 



From J. C. ARTHUR, Editor of The Botanical Gazette: "The first 

 botanical text-book issued in America which treats the most important 

 departments of the science with anything like due consideration. 

 This is especially true in reference to the physiology and histology of 

 plants, and also to special morphology. Structural Botany and clas- 

 sification have up to the present time monopolized the field, greatly 

 retarding the diffusion of a more complete knowledge of the science."

A guide to beginners. Its principles are, that the true aim of 

 botanical study is not so much to seek the family and proper 

 names of specimens as to ascertain the laws of plant structure 

 and plant life; that this can be done only by examining and 

 dissecting the plants themselves ; and that it is best to confine 

 the attention to a few leading types, and to take up first the 

 simpler and more easily understood forms, and afterwards those 

 whose structure and functions are more complex. The latest 

 editions of the work contain a chapter on the Gross Anatomy 

 of Flowering Plants. 



From J. T. ROTHROCK, Professor in the University of Pennsylva- 

 nia : " There is nothing superficial in it, nothing needless introduced, 

 nothing essential left out. The language is lucid ; and, as the crown- 

 ing merit of the book, the author has introduced throughout the vol- 

 ume ' Practical Studies,' which direct the student in his effort to see 

 for himself all that the text -book teaches."
