148 THE HOUSE FLY DISEASE CARRIER 



This, of course, means that there are more typhoid 

 germs in late summer and autumn, and as there are 

 at the same time more flies to carry them, the necessity 

 of destroying flies, especially in the early summer, is 

 emphasized by this conclusion. 



Other Points 



It may be that enough has been said on the subject 

 of the carriage of typhoid by flies, but there is a great

 Dr. J. W. Palmer of Ailey, Ga., for example, who has

 most part agricultural, although in a rich part of the 

 State of Georgia, informed the writer in the autumn

 without charge all cases of typhoid fever that develop 

 in houses well protected from flies, and states that he 

 has never had a case develop in such a house. 



In the Transactions of the Medical Association of 

 Georgia for 1910, an article by Doctor Palmer is pub- 

 lished on pages 149 to 157. In this paper he states 

 that he estimates that ninety-five per cent, of the ty- 

 phoid fever in rural districts may be laid to the typhoid 

 fly. He states that during the past typhoid season he 

 treated fever in several families, and especially noticed 

 that in the families which controlled the flies as di- 

 rected by him no new cases developed, while families
