this investigation supports the view , frequently entertained by clinicians , that the respiratory changes in the apices of the lungs are not as good as those of the rest of the lungs , and it disproves the claim of some physiologists that a decrease or increase of pressure at any part of the lungs must be equally distributed through all parts of the lungs , a claim based upon merely a priori physical considerations .
