Plain Facts for Old and Young is the Victorian sex-education manual of John Harvey Kellogg (1852-1943), the Battle Creek Sanitarium physician whose name survives on the cereal box. First issued in 1877 and endlessly enlarged, the book mixes anatomy and marriage advice with the doctor’s severe campaigns against self-abuse and stimulants, prescribing the graham-and-cornflakes regimen of his sanitarium. It is read now as a primary document of Victorian medical moralism at full strength. Free PDF download available on BDeBooks.
