THREE of the Four Divisions of the ENGLISH CYCLOPEDIA having been completed, and 

 the publication of the FOURTH DIVISION having commenced, the Proprietors desire to 

 call attention to the character of the Cyclopaedia, as a complete body of knowledge. 



As separate works, the nature of the Cyclopaedia of GEOGRAPHY, of BIOGRAPHY, of 

 NATURAL HISTORY, and of ARTS AND SCIENCES, is sufficiently clear. But, taken as a whole, 

 the connection of these great Divisions may require some very brief elucidation. 



If the English Cyclopaedia had been arranged in two Alphabets instead of in four, the 

 one department might have been caUed Literary, the other Scientific. 



The Cyclopaedia of GEOGRAPHY, and the Cyclopaedia of BIOGRAPHY, forming Ten 

 Volumes, embrace together not only the Description of every Country, but its History in 

 all ages. Under the Geographical name will be found a rapid view of a nation's progress. 

 Under the Biographical names will be found all the great public events, and the religious, 

 moral, and intellectual history of every State, as detailed in the lives of its eminent 

 citizens. 



The Cyclopaedia of NATURAL HISTORY, and the Cyclopaedia of ARTS AND SCIENCES, 

 now in course of publication, and forming also Ten Volumes, present every feature of 

 the Physical and Moral Sciences, and of the applications of Science to Productive Industry. 

 This concluding Division also embraces all branches of miscellaneous information not strictly 

 referable to these general heads. 



The English Cyclopaedia is founded upon the valuable Copyright of the Penny 

 Cyclopaedia, which has always remained in the hands of MR. KNIGHT. Every article in 

 that celebrated work was an original contribution, furnished by many of the most eminent 

 men of the time. The elaborate revisions, with the large additions, of the present work, 

 have involved a new outlay for literary labour of not less than Seven Thousand Pounds, 

 making the cost of literary production alone of these Twenty Volumes, not far short of 

 Fifty Thousand Pounds.
