The author defined ventilation as the complete removal of vitiated air and exhalations from a room as fast as they are produced, paired with introduction of an equal supply of pure air at the same time. This definition presupposed a scientific measurement of the amount of vitiated air and exhalations produced per minute, and apparatus capable of introducing the pure air regularly, under all circumstances. "Nothing is worthy, therefore, to be called Ventilation, that cannot show by measure the necessary number of cubic feet of air removed every minute, the year around." The author states his case rigorously for proper ventilation in all sorts of buildings, pointing to cases where stagnant air led to illness and death around the world. Representatives of many businesses were interviewed about their ventilating systems, and their statements are documented and indexed. An important topic of its day, which led to updated editions of this book.
