The world-wide interest which has been created during the last few years in the relation 

 which the house-fly bears to the hygienic state of the individual and of the community, as a 

 product of insanitary conditions and as a potential and not infrequent disseminator of certain 

 common and preventable infectious diseases, has rendered the presentation of our knowledge 

 of this insect, its habits and relation to disease most desirable and, indeed, necessary as a means 

 of appreciating its significance from the entomological and medical standpoint and as a basis for 

 further investigation.

"Dr Hewitt's little volume is especially comprehensive and well arranged. The book 

 contains a bibliography and is sufficiently indexed and illustrated, making altogether, perhaps, 

 as good a manual on the subject as could at the present state of our knowledge be produced in 

 similar compass." — Times 



FLIES IN RELATION TO DISEASE.

The author's main object in writing this book has been to collocate the more important 

 observations concerning the part taken by biting flies in the transmission of disease. In doing 

 this it seemed advisable to include notes on the classification of the flies concerned and also 

 descriptions of the infections transmitted, but no attempt has been made to give any account 

 of the clinical symptoms of the various diseases, whether of man or animals. Special attention 

 has been devoted to the modes of life of the more important insects mentioned, to the manner 

 in which the infection is transmitted from one host to another, and also to any preventive 

 measures directed either against the flies or the infections themselves
