Howard has taken 312 pages to tell the story of the species and its 

 iniquities and has done the work admirably. There is a frontispiece 

 showing Musca domestica in all its glory, and forty text-cuts. The 

 scope of the work is shown by the main headings of the various 

 chapters: Zoological Position; Life History and Habits; Natural 

 Enemies; Carriage of Diseases by Flies (typhoid fever, cholera, dys- 

 entery, diarrhea, tuberculosis, anthrax, yaws, ophthalmia, diphtheria, 

 smallpox, plague, tropical sore and parasitic worms) ; Remedies and 

 Preventive Measures; Other Flies Frequenting Houses; Bibliography 

 and five Appendices as follows: Flies Frequenting Human Dejecta 

 and those found in Kitchens ; On some Flies Reared from Cow 

 Manure; Regulations of the Health Department of the District of 

 Columbia Relating to House Flies; Orders of the Commissioners of 

 Columbia; Directions for Building a Sanitary Privy; A Simple Ap- 

 paratus for Use in the Safe Disposal of Night-Soil. 



Nothing of importance appears to have been overlooked and the 

 volume covers the subject in all its phases carefully and accurately.

The method of treatment is set forth in the preface : "The work 

 has been divided into sections mainly through an endeavor to show 

 the philosophy of evolution. First, I have brought forward sketches 

 showing special adaptations and animal behavior. Secondly, by 

 walks afield I have attempted in a simple manner to show the appli- 

 cation of evolution to the objects viewed. In the table of contents 

 will be found other subdivisions of the subject. When not other- 

 wise stated, these word sketches have been drawn from my diary 

 notes covering many years, made at Lakeside, Berrien County, Michi- 

 gan." 



On a frame-work of copious quotations, summaries and abstracts 

 of the works of the great and well known evolutionary biologists, 

 Dr. Hancock has hung his own observations as illustrations. He
