SCRIBNBR'S MAGAZINE. 



A remarkable number for November, containing : 



GEN. p. H. SHERIDAN'S ARTICLE "FROM GRAVELOTTE TO SEDAN." This paper, dealing 

 as it does with the author's experiences in the Franco-German War, covers a part of his career about which little 

 has been known, and the narrative now given to the world could have been written by no other hand than his own. 

 Durmg the war he ace impanied the staff of the Kmg of Prussia (afterwards William I. of Germany) as his special 

 guest. The pictures he gives of the struggle are as vivid as his position for observing it was unusual. The frontis- 

 piece of this number is engraved by Kruell from the last portrait taken of the author. There are also five full-page 

 engravings accompanying the article.

The publishers of Scribner's Magazine aim to make it the most popular and enterprising of 

 periodii:als, while at all times preserving its high litrrary character. 25,000 new readers have been 

 drawn to it during the past six months by the increased excellence of its contents (notably the 

 Railway articles), and it closes its second year with a new impetus and an assured suc- 

 cess. The illustrations will show some new effects, and nothing to make Scribner's 

 Magazine attractive and interesting will be neglected.
