Context: Rahn's talk "the influence of human radiation on micro-organisms" at the summer meeting of the American Association for the Advancement of Science (AAAS), Syracuse, June 1932.
What it reports Rahn as saying (paraphrase): radiation from the eye, the tip of the nose and above all the fingertips killed or slowed yeast; the right hand was usually stronger, even in left-handed people; the strength varied between people and in one person over time; sex made no difference; plant radiation usually stimulated, human radiation usually destroyed, through a difference of intensity, not kind; saliva of one woman stimulated yeast while her daughter's and husband's killed it; a woman who said she made flowers wilt radiated strongly. He suggested "magnetic personality" might involve a physical factor (newspaper wording).
Bearing: claim 6 (harmful human radiation); the inventor's own first public account, four years before the book, with details (eye, nose, right hand) to compare with Chapter IV and VII of the book. A newspaper report, not Rahn's text.
