The Barrel-shaped Chest.—-In the emphysematous (barrel-shaped) chest the normal elliptical form tends to become cyhndrical (thecylinder has a greater cubic capacity). The ribs are elevated and everted(position of forced inspiration); as a result of this the costal angle en-larges, the lower ribs flare upward, and the sternum is arched; whileLouis angle becomes prominent. These changes are bilateral and result from enlarged thoracic con-tents—enlarged lungs, emphysema. If the spine is also involved itbecomes bent backward, the shoulders are
