Having thus noticed, as extensively as our limits 
would allow, some of the most prominent external 
as well as internal peculiarities of birds, we shall 
now proceed to the consideration of the various 
species in detail, following pretty nearly the arrange-

and inserting additional observations and anecdotes, 
to illustrate those subjects on which we have already 
touched.
