ORDER II. 
Passeres. 
The character of this Order, the most numerous of the whole 
Class, seems at first to be simply negative, since it embraces all 
the Birds which are neither Palmipedes^ Grallce, Scansores, Ac- 
cipitres or Gallinacece ; comparison, however, presents a great re- 
semblance in their structure, and such insensible passages from one 
Genus to another, that it is very difficult to establish the sub- 
divisions. 
We find the Singing Birds and, consequently, the most com- 
plicated inferior larynxes (p. 7, note 2.) amongst the Passeres,

(1) Their mouth is consequently so very large that they easily swallow the insects 
which they take in their flight : being entirely insectivorous, they quit us in winter. 
They approach the tribe il/f/.^c/cflfjoflf, and especially the Procni as, yyhose heal scarcely 
differs but by the notch.
