The Discovery of Unsuspected Dangers,Before proceeding with my main subject, I am tempted to a short discussion of the extraordinary phenomenon of arthropod transmission of pathogenic organisms, which involves a little speculation about their evolutionary history.

This opportunity was not universally appreciated, but the path was blazed by some enthusiasts like Ronald Ross, Malcolm Watson and William Gorgas. D
