YELP. To bark in a particular way ; as, a 

 yelping cur. 



ZIGZAG. Having short turnings and angles. 

 ZOICED. Surrounded with one or more 



girdles. 

 Z0OGRAPHY. Zoology, which term is now 



generally used for the science that describes 



and classifies animals. 

 ZOOLOGY. That branch of Natural History 



The progress of science is daily effecting 

 modifications in the views which Cuvier 

 disseminated as to the classification of 

 animals in his famous work the 'Kegne 

 Animal;' but he will long be regarded, 

 both in France and in England, as the 

 loadstone of Naturalists, and the legislator 

 of Zoology. 



As the outward characters, '.habits, and 

 properties of living animals, their good 

 and evil relations to man &c., cannot be 

 profitably discussed within the limits as- 

 signed to this article, it will be confined to 

 the exposition of the principles of their i 

 classification, the reader buing referred to i 

 the various zoological articles interspersed 

 throughout the work for a full account of 

 the points above alluded to, and many 

 others too numerous to mention. 



The artificial system of classification 

 being now abandoned by the consent of 

 naturalists, no advantage would be gained 



hich treats of all the beings comprised in 

 the term " Animal Kingdom." It consists 

 of two grand divisions, Zoology Philoso- 

 phic, and Zoology Descriptive ; the former 

 embracing Comparative Anatomy and 

 Physiology, and all the great questions 

 relating to the succession of species of ani- 

 mals upon the earth, the parts they play 

 in the theatre of nature, and the geogra- 

 phical distribution of existing species ; 

 the latter being restricted to the outward 

 character, habits, properties, and classifi- 

 cation of animals. Thus in its most com- 

 prehensive sense, Zoology constitutes the 

 most important branch of Natural History, 

 the science at once most worthy to fasci- 

 nate the attention, by the vast tableau of 

 animated nature it discloses to view, and 

 perhaps best calculated to elevate the sou 

 to the perception of a wise and good Pro- I or fossil,

by detailing it in this place, and we shall 

 therefore confine ourselves to an outline of 

 the system of the great Cuvier, which, as 

 already explained, has taken Nature for 

 the basis of its distributions. According 

 to Cuvier, the Animal Kingdom is prima- 

 rily divided into four provinces or sub- 

 kingdoms, viz. Vertebrata, Mollusca, Ar- 



d i ticulata, and Radiata.

 and an Owen.
