PREFACE, 



the appending of notes, which always divide the attention of the reader, and 



Aveaken the interest of the subject. Many of the chisses and orders have 



been reinvestigated, and many new species added. This is most extensively 



done in the departments which were intrusted to Mr. Bia'tii and Mr. West- 



Vv'OOD ; but it runs more or less throughout the whole ; and the publishers 



; flatter themselves that this will be of <?reat service to all students of this 



I highly interesting branch of knowledge. The different sizes of type, wliich 



1 bear some proportion to the comparative importance of the subject, will 



enable the reader to glean an outline of the system ; — to obtain something 



more than a bare outline, he must read the entire work. 



To these remarks which were appended in 1846 to the first edition, the 

 publishers may be permitted to add a few words respecting the present re- 

 print. It was not considered desirable to disturl) the illustrious author's 

 arrangement by the introduction of a more mi^dern svstem, nor was it 

 thought proper to overlook altogether, in a work professing to give a com- 

 plete view of Animated Nature, the results of modern investigation. 1 he 

 pirblishers have, therefore, added supplementary articles to such branches 

 i as seemed to require it; Dr. Carpenter kindly supplying what was 

 wanting to the IMoUusea and Fislies, and Mr. Westwood performing the 

 same to his own department of the Avork. 



In addition to these improvements, the work is now illustrated by thirty 

 plates of Animals, etched by ]\Ir. Tiiojias Landseer, and four plates re- 

 presenting the different races of Mankind ; and the publishers present it in 

 its present form in the belief that it will merit public approbation.
