THE YOUNG OOLOGIST. 



I'd 



other important publications, having ap- 

 peared in the interval between the first and 

 second editions of the "Key." 



The amount of matter has been nearly- 

 quadrupled; the number of illustrations, 

 many of them engraved expressly for this 

 edition, has been more than doubled. The 

 old "Key" contained 361 pages and 238 

 cuts; the new "Key" contains 900 pages 

 and 562 cuts, with a colored frontispiece. 

 By the use of a smaller type and closer page, 

 this great increase in the text and illustra- 

 tions has been secured without materially 

 increasing the bulk or the cost of the volume. 



Part I of the "Key" consists of Coues' 

 "Field Ornithology," originally pubhshed 

 in 1874, and now for the first time incorpo- 

 rated with the "Key." This treatise takes 

 the student and amateur directly into the 

 field, and teaches him to become an expert 

 collector and skillful taxidermist. It shows 

 him how to be a field naturalist in the best 

 sense of the word — how to study birds in 

 their haunts, and how to collect and preserve 

 them, with their nests and eggs. 



Part II, an elaboration of the introductory 

 matter of the old "Key," is in itself a full 

 treatise on the external and internal stnic- 

 ture of birds, the classification and nomen- 

 clature, etc., teaching the technicalities of 

 the Science of Ornithology. 



Part III, occupying the body of the work, 

 is a systematic synopsis of the birds of North 

 America, giving concise but ample descrip- 

 tions of some 900 species and 350 genera, 

 with the characters of the families and or- 

 ders to which they belong ; with convenient 

 analyses of the species under theii- respective 

 genera, of the genera under their respective 

 families, etc., the technical descriptions of 

 the species, usually including brief but tell- 

 ing notices of their habits, haunts, migra- 

 tions, song, nests, eggs, etc., together with 

 a full statement of geographical distribution 

 in each case. The spirit and design of the 

 old " Key" are thus kept fully in view; it 

 being the pecuhar province of this work to 

 enable anyone who masters the rudiments of 

 the science to name and classify specimens. 



Part IV, corresponding to the aiDpendix of 

 the old "Key," is a synopsis of the Fossil 

 Birds of North America. 



The "Key" is profusely illustrated with 

 wood-cuts in the text, of an average excel- 

 lence far beyond those of the former edition. 

 The work is fully indexed with several thou- 

 sand entries. An historical jDreface sketches 

 the progress of North American Ornithology 

 for more than two centuries. The whole 

 forming the latest and most exhaustive 

 American Ornithology. Indispensable to 

 every sportsman, amateur, and working or- 

 nithologist. The whole work is complete 

 in one stout but portable volume.
