BOOK NOTICES. 



Appleton's Annual Cyclopedia. Vol. XXI, 1881. Octavo, pp. 905; cloth, 

 $5. For sale by L. B. Bailey, General Agent, Kansas City, Mo. 



This is the sixth volume of the new series, and the twenty-first of the whole 

 series. The publishers truthfully and aptly say, "It has grown in size to meet 

 the increased activity in human affairs and to present the interesting public ques- 

 tions and scientific developments which have arisen and the discussion of their 

 principles." 



Among the historical subjects presented, none is more interesting at the pre- 

 sent time than the summary of the Garfield assassination; the trial of Guiteau; 

 the discussion of the insanity question ; the history of the treatment of the Presi- 

 dent's case, etc. All of the stirring events in South America, Russia, Germany, 

 France, Italy and Spain, are carefully summarized under proper heads by the 

 most competent writers. 



The progress of science is given with unusual minuteness and accuracy, 

 whether in chemistry, philosophy, engineering, electricity, physics or zoology. 



The results ol the loth Census are given a large space and illustrated with 

 reduced copies of the maps showing density of population, native, colored and 

 foreign. 



Four fine steel portraits, as usual, embellish the volume, viz : Longfellow, 

 Blaine, President Arthur and Gambetta, in addition to which are numerous maps 

 and other illustrations. 



No book or publication of any house in the United States equals this in value 

 or importance to the reading public. Each volume brings the world's, history 

 forward in a convenient, comprehensive and strictly reliable form and at a price 

 within the reach of all classes.

 the currents of the ocean with all the naturalness and vividness of a voyager, and 

 the reader can almost see them pouring their mighty floods toward the Pole. The 

 address gives a valuable sketch of the explorations and discoveries made in the 

 Arctic Seas since 186S. The main object of the lecture is to show that the ocean 

 currents open the natural highways to the Poles, and should be followed by the 

 Arctic explorers if they would attain any substantial results. The theory is well
