THE REPORT OF THE 



No. 19 



The most marked recognition of the mosquito danger ever displayed was 

 in the fight carried on against the recent epidemic of yellow fever at New 

 Orleans, La. The surgeons in charge accepted the theory of transmission 

 by Stegomyia only and bent all their efforts first, to the destruction of the 

 Stegomyia, and second, to protecting patients and others from mosquito bites. 

 As to the habits, etc., of this species I must speak at second hand, since it 

 does not occur in New Jersey.
