SCIENTIFIC BOOKS. 

 General Zoology. Practical, Systematic and 



Comparative. By Charles Wright Dodge. 



New York, American Book Company. Pp. 



512; 379 figs. 



As stated on the title-page, this work is a 

 revision and rearrangement of Orton's ' Com- 

 parative Zoology.' It is evidently designed 

 for elementary instruction in high schools, 

 academies and colleges. About one third of 

 the volume is devoted to a brief systematic re- 

 view of the animal kingdom, the remainder 

 to ' comparative zoology,' that is, a mixture 

 of animal physiology, comparative anatomy, 

 embryology, ethnology, distribution, etiology, 

 etc. In the main, the work has been care- 

 fully written, though certain statements should 

 be revised or corrected in a possible new edi- 

 tion. The insect figured as a cricket (Gryllus) 

 on page 109 is a locustid, and the dragon-fly 

 on page 111 is not a Lihellula. The bird 

 figured on page 172 is the resplendent trogon 

 (Pharomacrus mocinno) and not Trogon ele- 

 gans, which is a very different creatui-e. 

 Although the classification adopted is that of 

 Parker and Haswell, the author includes the 

 apocryphal group Mesozoa, at least in the 

 ' ancestral tree ' on page 201, though nothing 

 is said about it in the text. Amphioxiis is 

 still regarded as a vertebrate, though this 

 term is properly applicable only to the Crani- 

 ota. In the chapter on the distribution of 

 animals there are a few sweeping and inac- 

 curate statements. On page 441 the author 

 says : ' Each of the three great provinces, 

 Earth, Air and Water, as also every continent, 

 contains representatives of all the classes; but 

 the various classes are unequally represented.' 

 This sets one to wondering whether the Amer- 

 ican fauna may not comprise such things as 

 flying tunicates and aerial holothurians, and 

 whether terrestrial cyclostomes may not be 

 discovered in the remoter regions of the ' dark 

 continent.' In the chapter on the origin of 

 animal species the definition of ' organic selec-
