The first volume of this work comprised an out- 
line history of the Raptorial Birds, together with 
that of the Dentirostral tribe of the Insessorial 
Order. In the present we lay before our readers 
the remainder of the Insessorial Order, com- 
prising the several Tribes, Eissirostres, Scansores, 
Tenuirostres, and Conirostres. The whole work 
will be completed by the publication of the third 
volume^ which will comprehend the Orders 
Rasores, Grallatores, and Natatores: orders in 
which are placed several domestic and wild 
families well known and valued in this countrv. 
We, therefore, confidently expect that it wdll 
possess, for the majority of our readers, greater 
interest than the portions already published.
