No sharp line of demarcation exists betweenthese sections, but the latter is regarded as constitutingsomewhat more than half the whole. The ileum finallyarrives at a point not far from the crest of the right hip-bone and there enters the large intestine. The large intestine is so called from its diameter, whichis two or three times that of the small. It is quite as often.

A dotted line is used to complete the form of the pancreas,which discharges to the intestine near W The shape of the stomachis of one moderately filled; with further distention the lower borderof the organ would sag and the pylorus would cease to be the lowestpoint.

Beginning with a small rounded pouch,the cecum, from which hangs the infamous appendix vermi-formis, it may be followed upward on the right side ofthe body to the level of the lower ribs. This part is theascending colon. From here it bends sharply to the leftand crosses the full width of the abdominal cavity. Thishorizontal segment is known as the transverse colon andlies close to the ventral body wall. Thus it passes in fro
