" It is a book of inestimable value to the naturalist, and should 

 be found in the library of every such person in the land." — Boston 

 Traveller. 



" We have no hand-book of similar character, and none that 

 occupies the place it completely fills." — Golden A>je. 



" A thorough and reliable treatise, comprehending the entire 

 subject." — American Sportsman. 



" We can cheerfully recommend it to those who wish a reliable 

 manual of the birds of North America, in a sufficiently portable 

 form for ready reference." — The Independent. 



** The only general exposition of this department of American 

 ornithology that has yet been made." — Atlantic Monthly. 



" There is a freshness and boldness in the manner in which facts 

 are handled, which will be extremely acceptable." — Nature. 



"No expense has been spared in the preparation of this volume. 

 The woodcuts are so well executed they would easily pass for somo- 

 thing better. The index is complete; so is the glossary." — Chicago 

 Times. 



"The descriptions are exceedingly complete and minute; the 

 large number of illustrations serve to make the text more clearly 

 understood, and the volume is a very valuable contribution to or- 

 nithology." — Boston Journal. 



"With the help of this 'Key' the veriest tyro can, with very 

 little trouble, identify his specimens, and obtain a knowledge and 

 understanding of American birds, impossible to be found in any 

 other work." — Army and Navy Journal. 



" This book will be welcomed both by the amateur and profess- 

 ional ornithologist as a valuable contribution to the list of books 

 treating of North American birds. While Dr Coues has modestly 

 called his work a ' Key,' it is in reality much more than the title in- 

 dicates. The typographical execution of the work is in every way 

 worthy of it, and the cuts are very clear and instructive." — The Na- 

 tion. 



"A more elegant scientific publication than the 'Key to North 

 American Birds,' just issued by this house, is not to be found. 

 This work, of which Elliott Coues, M. D., is the author, forms a 

 very valuable and exhaustive treatise upon the birds of the conti- 

 nent north of Mexico. The large number of plates and of wood- 

 cuts, renders it especially interesting, and the style of its publica- 

 tion is almost sumptuous." — Boston Post.
