 15 cents will be paid, or any other two past or future numbers will

 S. Review, 525 W. 120 St., New York. 



MENTION THE REVIEW TO ADVERTISERS 



One advertiser writes that he had no returns from a review 

 and advertisement in The Review ; but the Managing Editor 

 happens to know that several students learned ot the book by 

 reading this magazine and ordered ^copies through a local book- 

 store. Doubtless many other readers have done the same thing. 

 Now it will help the financial department of this journal it 

 readers will write to publishers and state that they have been 

 interested in reviews and advertisements in The Nature-Study 

 Review. Kindly do this even if your orders are sent through 

 your local bookstore. Many publishers are interested in the 

 pages announcing new books and they naturally want to know 

 whether The Review reaches readers who buy nature-study 

 and science books.
