ENTOMOLOGY WITH SPECIAL REFERENCE TO ITS BIOLOGICAL AND ECONOMIC 

 ASPECTS. By JUSTUS WATSON FOLSOM, Sc.D., Assistant Professor 

 of Entomology at the University of Illinois. Second Revised 

 Edition. * With four plates and 304 text-figures. Philadelphia : 

 P. Blakiston's Son & Co., 1913. Price $2.25. 



The second revised edition of this well and favorably known 

 book appears as a thinner volume than the first edition. The size of 

 the page remains the same, but the type form is 5^ inch longer and 

 Yz inch wider, so that, in spite of much additional matter, although 

 with the omission of one chapter, the number of pages is reduced from 

 vii + 485 to vii + 402. The paper is also a little thinner. 



The numbering and titles of the chapters remain as in the first 

 edition as far as Chapter VI and after Chapter X. Chapter VII of the 

 first edition, "Origin of Adaptations and of Species," is omitted in the 

 second. Chapter VIII, of the former, corresponds to No. VI! of the 

 latter. Chapter IX of the first, "Insects in Relation to Other Animals," 

 is expanded into Chapters VIII and IX of the second edition, VIII 

 having the same title as the former IX, while the new IX is "Trans- 

 mission of Diseases by Insects." 



Numerous additions to and revisions of the text have been made, as 

 for example on pages 5 (on the new order Protura), 51. 85, m, 104-5, 

 105-6, 117, 125, 165, 174, 187, 193, 198, 211, 269, 33.3. 336' 337- f thc 

 new edition, as compared with the corresponding passages of the old.
