ZOOLOGY. 



Dodge's General Zoology.' — The title on the cover and the "book 

 notice" sent out by the publishers do not suggest that this is other- 

 wise than an entirely new book, but in small type on the title page is 

 the information that this is a " revision and rearrangement " of Orton's 

 Comparative Zoology — a well-known text-book written in 1876 by the 

 late Professor Orton of Vassar College and revised by Birge in 1883 

 and by Dodge in 1894. But even the information on the title page 

 does not prevent the reader from expecting to find that the new 

 author and new title mean that the book has been recast so com- 

 pletely that the original author deserves credit for only a minor part 

 of the book. Careful examination leads to disappointment. Parts I 



there are two new chapters — one on practical work and the other on 

 origin of animal species. In all other respects, the chapters, sections, 

 and paragraphs of the greater part of the book stand essentially 

 unchanged, except in minor verbal changes and revisions of the 

 classification and morphology in accordance with discoveries made 

 since the original book and its earlier revisions appeared. Thus 

 Dodge's General Zoology is analyzed into Orton's Cornpara tire Zoology 

 with probably 90 per cent of the sentences essentially as Professor 

 Orton wrote them thirty years ago, and added to this about forty 

 pages of new material. In the light of these facts any fair-minded
