NOTICE. 



The present extract constitutes the Zoological portion of the work entitled — 



" Iconographic Encyclopedia of Science, Literature, and Art. Systematically 

 arranged by J. Gr. Heck, translated from the German with additions, and edited by 

 Spencer F. Baird, A. M., M. D., Professor of Natural Sciences in Dickinson 

 College, Carlisle, Pa. Illustrated by five hundred steel plates, containing upwards 

 of twelve thousand engravings. In four vols. 8vo. of text, and two vols, oblong 

 quarto of plates. New York, 1851. Published by Rudolph Garrigue, 2 Barclay 

 St., Astor House." 



Much of the Encyclopedia, instead of being translated, has been entirely re- 

 written, with special reference to adaptation to this country. The part on Zoology, 

 among others, has been compiled entirely anew by its authors, and will be found to 

 contain much original matter never before published. 



The references to the plates are retained in this extract, though the plates 

 themselves are not supplied. 



SPENCER F. BAIRD.
