“Numerous experiments with germs conducted in the past have conclusively proven that bacteria does not and cannot produce disease in a healthy organism. Years ago, Dr. Pettenkofer, professor at the University of Vienna, came to the conclusion that germs alone do not produce pathology and for years defended his position from the lecture platform and in his writings. On more than one occasion he and his assistants swallowed the contents of glasses containing millions of living cholera germs. Dr. Thomas Powell of California, who is believed to have taken more germs than any other man, challenged his medical colleagues to produce a single disease by germ inoculation. He was inoculated with cholera germs, bubonic plague germs and bacteria of every description and which was fed to him in every kind of food, yet nothing happened.
