excluded, we feel confident that the publication 

 of these observations must excite renewed in- 

 terest in the mosquito-theory of the propagation 

 of yellow fever, as first proposed by Finlay. 



From the first part of our study of yellow 

 fever, we draw the following conclusions : 



1. The blood taken during life from the gen- 

 eral venous circulation, on various days of the 

 disease, in 18 cases of yellow fever, successively 

 studied, has given negative results as regards 

 the presence of B. icteroides. 



2. Cultures taken from the blood and organs 

 of 11 yellow fever cadavers have also proved 

 negative as regards the presence of this bacillus. 



3. Bacillus icteroides (Sanarelli) stands in no 

 causative relation to yellow fever, but, when 

 present, should be considered as a secondary 

 invader in this disease. 



From the second part of our study of yellow 

 fever, we draw the following conclusions : 



The mosquito serves as the intermediate host- 

 for the parasite of yellow fever, and it is highly 

 probable that the disease is only propagated 

 through the bite of this insect.
