APPLETONS' 



POPULAR SCIENCE 



MONTHLY. 



EDITED BY WILLIAM JAY YOUMANS. 



$5.00 per annum ; single copy, 50 cents. 



APPLETONS' POPULAR SCIENCE MONTHLY is always 

 prompt to present the expert treatment of important 

 topics of the day, which are within the wide range of 

 its interest. It deals particularly with those general and 

 practical subjects which are of the greatest interest and 

 importance to the people at large. All its articles are by 

 writers of long practical acquaintance with their subjects, 

 and are written in such a manner as to be readily under- 

 stood. 



In the last few months the magazine has offered 

 Mr. MCPHERSON'S lucid discussions of the Monetary and 

 Banking Problem, and the studies of "The Social 

 Functions of Wealth," by M. PAUL LEROY BEAULIEU. To 

 these articles, and to the series by the Hon. DAVID A. 

 WELLS upon " The Principles of Taxation," not yet com- 

 pleted, it is possible now to add the announcement of a 

 most important and timely study of "The Present 

 Financial Problem," by Mr. WELLS, which will begin 

 probably in the September number.
