“ This book is not intended as a popular treatise on the subject. It is primarily intended 
for the use of entomologists, medical men, health officers, and others interested in health 
questions. It contains descriptions of the structure and habits of the house-fly, its breeding 
habits, and the life-history and structure of the larvae. A chapter is given to the natural 
enemies and parasites of the house-fly, and other species of flies frequenting houses are 
described. The final chapters relate to the connection of house-flies with disease, and the 
control measures that are available for limiting the numbers of flies.. .. The book is exceedingly 
well illustrated, and fuU acknowledgment is made of the contributions of other workers in 
the same field. Dr Gordon Hewitt is to be congratulated on the production of a work of 
such high authority, which wfll be consulted by aU those who are interested in this branch 
of science .”—Journal of the Royal Sanitary Institute
