The mternal intercostal muscle, the thin intercostal fascia and the weakest portion ol the great pectoral and the external oblique, together with the common fascia are, besides the skin, the only coverings of the pleural sac in this situation. Pro- fessor Marshall claims that spontaneous perforation of an empyema generally takes place at this spot.
