Witho^tt Mosquitoes there can he no Yellow 



Fever: James Carroll. 



It seems incredible, but is, nevertheless 

 true, that at the present time there are still 

 in the United States many physicians who 

 oppose the idea that the mosquito is the 

 sole means by which yellow fever is carried 

 from one person to another. They refuse 

 to believe that the natural disease can not 

 be contracted in any other way than 

 through the bite of the mosquito. The 

 fact, however, has been repeatedly demon- 

 strated and the evidence in its support has 

 now become overwhelming. The tremen- 

 dous importance of this subject, in a city 

 which, by reason of her location and com- 

 mercial intercourse with Central and South 

 America, may be regarded as the gateway 

 through which a disastrous epidemic may 

 at any time be introduced into the United 

 States, is my apology for again taking up 

 so trite a subject. It is the duty of those 

 who are familiar with the facts to com- 

 municate them to the melnbers of the pro- 

 fession, for the people must rely upon their 



''i^.
