OF THE DIVISION OF THE CLASS OF BIRDS. 



THE Linnaean divifion of birds is only into fix orders, which the illuftrious mafter 

 of our fcience confiders as having fome analogy with the fir ft fix orders of the clafs of 

 Mammalia, excluding the order of Cete. 



I. Accipitres, analogous to the Ferae. 

 II. Picffi, analogous to the Primates. 



III. ANbERES, analogous to the Betluae, 



IV. Grall^e, analogous to the Bruta. 

 V. Galling, analogous to the Pecora. 



VI. Passeres, analogous to the Glires. 



In the following divifion of the clafs into orders, the Linnaean arrangement is pre- 

 ferved j but, in imitation of the celebrated ornithoiogift Mr Latham, three additional 



orders
