We base our deter-minations of the relaxation of the diaphragm upon thecharacter of the abdominal respirations. Normally, when THE SIGNS OF ANAESTHESIA 105 inspiration takes place, the diaphragm moves downwardupon the abdominal viscera and causes a distention of theabdomen, which raises the abdominal wall (Fig. .59). Theamount of the abdominal movement is greatest during theperiod of excitement when the movements of the diaphragmare excessive. As anaesthesia progresses, these move-ments become less, but the abdomen still swells upon in-spiration. If the level of the anaesthes
