THE STORY OF AN ENTOMOLOGIST 



the party that included Pothier and Beyer of New Orleans, 

 and that had been sent out to investigate the cause of Yellow 

 Fever. They were sent by the United States Public Health Serv- 

 ice, and it may be remembered that they reported that they had 

 discovered the causative organism. It may also be remembered 

 that a later party, headed by Rosenau, sent out by the same

 his family, reached Vera Cruz, in a deplorable state of health

 General Funston was in command of the American Expedi-

 him, telling him of Herrera and of the help he had been to the 

 United States government by his kindness to our experts. Gen-
