IT IS THE 



ONLY GREAT 



REVIEW 



A LIBRARY OF 



THE ABLEST 



THOUGHT ON 



ALL 



GREAT LIVING 



ISSUES. 



SOME POINTS WORTH REMEMBERING. 



Is recognized as the most liberal, progressive, and impartial great 



review published. 

 Employs the boldest, ablest, and most authoritative thinkers in the 

 New World and the Old, to discuss all the great social, economic, 

 ethical, educational, and religious problems of the day. 

 In its discussions of all the great living problems, strikes at the 

 very root of the question, instead of wasting time on mere results or superficial as- 

 pects of the same. 



Its contributors are largely among the vanguard of the world' s thinkers and reformers, 

 hence it discusses problems six months to a year before the slow coaches reach them. 



SOME FACTS WORTH NOTING. 



I. Which monthly gives portraits of the world's great thinkers. 



II. Which richly illustrates important papers calling for illustrations. 



III. Which gives its readers a brilliant story by a strong American 

 author each month. 



IV. Which regularly publishes critical and biographical sketches of 

 illustrious personages by the ablest writers of the age. 



Which in addition to its regular one hundred and twenty- eight pages of reading-mat- 

 ter, monthly publishes from twelve to sixteen pages of critical review of books of 

 the day by scholarly writers. 



SOME THINGS WORTH CONSIDERING. 



(1.) One year's subscription to The Arena comprises two volumes 



OF OVER SEVEN HUNDRED AND FIFTY PAGES EACH. (2.) ThE ARENA Con- 

 tains the ablest contributions from the master brains of America and 

 Europe on all the great Social, Religious, Educational, and Ethical 

 problems of the age. It is a compendium of the best thought on the 

 great living questions of the age that most intimately affect civilization, 

 published in the New World. (3.) The Arena gives all sides of every 

 great issue, presented by the strongest advocates, as the editor believes 

 that it is only in the crucible oi free discussion that we find the gold of 

 truth. (4.) Every subscriber to The Arena receives annually a library 

 ■of the finest writings, condensed so as t9 meet the demands of a busy age, yet elaborate 

 enough to give every reader a clear and comprehensive view of tiie various salient points, 

 advanced by friends and foes, of the leading issues of the hour. More than fifteen hun- 

 dred pages of the most profound, able, and advanced thought are received by every yearly 

 -subscriber to The Arena

PROPRIETARY. 



Scrofula is, in the main, a 

 disease of early life. Home 

 knowledge is all astray about 

 it. You cannot tell whether 

 your child has it or not; your 

 doctor will know. 



We do not prescribe. We 

 are chemists. We make the 

 remedy, Scott's Emulsion of 

 cod-liver oil. Your doctor 

 must tell you when to use it. 



A book on careful living 

 tells what scrofula is. Shall 

 we send it ? Free.

The pictures hare come, and the 6 large seated and

 for (& that's saying a good deal, for I have sat to all 

 the dons in New York— and in all the cities too from 

 Boston to New Orleans). But I want a dozen of them, 

 not 6 as you sent. 



Please print me six more, same style, on the large plain
