tonic four to six hours,and the atonic six to eight hours. The form of the normal stomach and its position depend largely uponthe shape of the upper abdomen and the general anatomical characteristicsof the individual. When the intercostal angle is wide and the upper abdomenis broad, the stomach assumes an oblique position. With a narrow upperabdomen and a more acute intercostal angle, the stomach is perpendicular.Thus, in some individuals an atonic type of stomach is normal, i.e. if itsfunction is not delayed, while the same type in an individual of a differentbuild, but incapable of emptying itself, is the result of a ptosis. Again ahypertonic form of stomach may be found where the abdomen is broadand the intercostal angle wide, and yet it will be found to be orthotonic oreven hypotonic.

FUNCTIONAL DISTURBANCES OF THE STOMACH 221 an indication of its muscular tone. The empty normal stomach lies inthe form of a collapsed tube, with its walls in contact, except in the fundus,which contains the so-called magenblase. (See Fig. 164.) A portion ofthe opaque meal is first seen in the upper part as a funnel-shaped shadow,which is quickly forced downwards, separating the walls, and finally reach-ing the sinus, and filling the pyloric canal. The length of the stomachremains fixed, while the corpus, sinus, and pyloric canal increase in girth, andaccommodate themselves to the amount of the meal ingested. This type offilling phenomena is characteristic of the orthotonic stomach.
