[jPns work is divided into three parts — an Introduetion, giving 
a popular elementary explanation of the leading principles of or- 
nithology, an analytical Key to the North- American genera and 
subgcnera, and a Synopsis of the species. The Key is the most 
original part, forming an artificial analysis to facilitate the dis- 
covery of the name of any bird which may chance to come into the 
hands of one who knows nothing of the subject^and as such is 
much to be commended. The drawbacks of the book are its 
size, to some extent unavoidable, and the very poor character of 
many of the woodcuts. Much of tlm Introduction will be found 
useful to learners in all countries. (The Synopsis of Fossil Forms 
is a novel feature ; and from it 29 species appear to have been 
distinguished in the United States. [C/*. Am. Nat. vi. pp. 478,

The beginning of a new work, which seems to be very fairly 
done. The prospectus,^^ printed on the wrapper, announces 
the discovery of a new species (Emherizidoi) , but it is identical 
with one already described (c/, Zool. Rec. viii. p. 66).
