198 THE CANADIAN ENTOMOLOGIST 



in the Quarterly Journal of Microscopical Science in 1907, 1908 

 and 1909, and was republished in book form, together with several 

 appendices in 1910 by the Manchester University Press. This 

 edition was ver}- limited and was soon exhausted, and as much new 

 material had been brought to light by subsequent investigators in, 

 various countries, the author deemed it necessary to prepare a com- 

 pletely new work, bringing the subject matter thoroughly up to date. 



The book is divided into six parts as follows: Part I — The 

 Structure and Habits of the House-fly. Part 2 — The Breeding 

 Habits, Life History and Structure of the Larva. Part 3 — The 

 Natural Enemies and Parasites of the House-fly. Part 4 — Other 

 Species of Flies frequenting Houses. Part 5 — The Relation of 

 House-flies to Disease. Part 6 — Control Measures. 



Of the 27 chapters, those dealing with structural matters are 

 but slightly modified from the author's original accounts of these 

 subjects. All the others contain a large quantity of information 

 not found in the earlier work. This is especially true of Part 5, 

 in which six chapters are included, an entire chapter being devoted 

 to "the carriage of typhoid fever by flies," and-another to "the 

 relation of flies to summer diarrhoea of infants." In these and the 

 other chapters of Part 5 the enormous literature dealing with 

 experimental investigations in the dissemination of bacterial 

 diseases and parasitic worms by flies is very carefully and concisely 

 summarized and will prove of great interest and value to physicians 

 and public health officers. 



Following Part 6 is a bibliography of 36 pages and two indices, 

 an author's and a subject index. 



This book will undoubtedly remain the chief source of informa- 

 tion on the house-fly for many years to come and will rank as a 

 classic for all time.
