For example, fifteen or sixteen police agents were sent to Ostia, and though they only remained a night in the place, they all developed fever.—The daily papers report that the Finlay theory of the propagation of yellow fever by mosquitoes has been further confirmed by the commission now studying the subject in Cuba.
