It is advis-able before arriving at a definiteconclusion to corroborate theobservation by an examinationon a subsequent day. The causeof the stasis will be made outfrom what has been said aboutgastric disorders. The next common site forintestinal stasis is in thelast few inches of the ileum ^— ileal stasis. We have seenthat it takes about four hoursstomach, and it takes about the same time to pass fromthe stomach to the caecum; consequently we must expect
