The question as to which lobe under similar conditions is more benefited by paralysis of the diaphragm is still unsettled. Some surgeons report more favorable results on lesions of the lower lobe; others believe that the upper and lower lobes are equally benefited. With that issue in view, these experiments were carried out.

EXPERIMENTAL METHODS No method has been devised by which the respired air from an individual pulmonary lobe can be measured satisfactorily, but one would expect the changes in the bronchial
