    Stagnation of feces in the rectum is only one of the ways in which passage of material through the alimen- tary canal may be delayed. In this form, for which Hertz has revived the. name “dyschezia,”?* ‘the rate of movement through the entire length of the digestive tract, as far as the pelvis, may be normal, but the rectum and pelvic colon-are not properly emptied. In other forms there may be delay somewhere in the long course which the food takes, because of inefficient motility, as in states of general atony, in depressive emotions, and in reflex inhibitions of intestinal movements. In still other cases the delay may be due to obstructions of various sorts. In distinguishing these various causes of delay in the passage of material through the alimentary eanal, the x-ray method has provided a highly important aid to other methods of clinical examination. 23.
