Eepresents the antero posterior section of the thorax, or chest, when thelungs are contracted. 1, 1, The diaphragm. 2, 2, The muscular walls of the abdo-men. These engravings show the diaphragm to be more convex, and the walls of the ab-domen more flattened, when the lungs are contracted, than when they are inflated. 7th. Restricting the movements of the ribs and diaphragmimpairs digestion, not only by preventing the oxydation of theblood in the lungs, but by impeding the action of the abdomi-nal organs, induced by the elevation and depression of the dia-phragm. At each full inspiration, the ribs are elevated, andthe central portion of the diaphragm is depressed, from one totwo inches. This depression is accompanied by a relaxationof the anterior abdominal muscles. A
