THE ENCYCLOPEDIA AMERICANA: 



A POPULAR DICTIONARY 



OF ARTS, SCIENCES, LITERATURE, HISTORY, POLITICS 

 AND BIOGRAPHY. 



IN FOURTEEN LARGE OCTAVO VOLUMES OF OVER SIX HUNDRED DOUBLE 

 COLUMNED PAGES EACH. 



For sale very low, in various styles of binding. 



During the long period which this work haa been before the public, it 

 has attained a very high character as an 



ENCYCLOPAEDIA FOR DAILY REFERENCE, 



Containing, in a comparatively moderate space, a vast quantity of informa- 

 tion which is scarcely to be met with elsewhere, and of the exact kind 

 which is wanted in the daily exigencies of conversation and reading. It 

 has also a recommendation shared by no other work of the kind now before 

 the public, in being an American book. The numerous American Biogra- 

 phies, Accounts of American Inventions and Discoveries, References to our 

 rolitical Institutions, and the general adaptation of the whole to our own 

 peculiar habits and modes of thought, peculiarly suit it to readers in this 

 country. From these causes, it is also especially fitted for all 



DISTRICT SCHOOL AND OTHER PUBLIC LIBRARIES, 



in some of which it has been tried with great satisfaction. It fulfils, to o 

 greater extent than perhaps any similar work, the requirements for these 

 mstitutions, presenting, in a small compass and price, the materials of a 

 library, and furnishing a book for every-day use and reference, indispensablo 

 to those removed from the large public collections. 



'i3omo years having elapsed since the original thirteen volumes of the 

 ENCYCLOPAEDIA AMERICANA were published, to brin^ it up to 

 the present day, with the history of that period, at the request ofnumerous 

 subscribers, the publishers have just issued a 



SUPPLEMENTARY VOLUME (THE FOURTEENTH), 



BRINGING THE WORK UP TO THE YEAR 1847 



EDITED BY HENRY VETHAKE, LL.D. 



Vice-ProTost and Professor of Mathematics in the University of Pennsylvania, Author of 

 "A. Treatise on Political Economy." 



In one large octavo volume of over 650 double columned pages.
