 clusive results of Finlay,** Carter, ff Reed, Carroll, Lazear, 

 and Agramonte,JJ and Reed and Carroll, which have 

 proved the mosquito to be the definitive host of a parasite 

 probably belonging to the animal kingdom. Two of the 

 described bacteria, however, deserve mention, not because 

 they have much probable connection with yellow fever, but

Sternberg || || reported the study of 42 yellow fever autopsies 

 in which aerobic and anaerobic cultures were made from 

 the blood, liver, kidney, urine, stomach, and intestines, but 

 the specific infectious agent was not found, and the most 

 approved bacteriologic methods failed to demonstrate the
