The etiology of abscess of the lung, particularly that which occurs after surgical operations, has been subject to recent clinical and experimental investigation, and much of pertinent data has been revealed. In the interpretation of this, difference of opinion has arisen as to whether inoculation of the lung occurs by aspiration of infectious material from the mouth or by embolism from an infected surgical wound. In favor of each has been presented a mass of clinical facts, and it must be admitted that most of these facts can be used equally effectively on either side of the argument. Also, experimentally, it has been possible to reproduce abscess of the lung by either portal of inoculation in substantiation. The aspiration theory has, however, been adopted by the majority as the more plausible. A critical review of the situation readily demonstrates essential defects in both explanations when applied to the etiology of
