The movable portion of the appendix may be met with in dif- ferent situations. It may pass upward and in front of the cecum and colon, upward and behind the cecum, and even behind the colon betwe>rn the two layers of the mesocolon; upward and to the inner side or upward and to the outer side of the cecum and colon. It may pass to the left under the ileum and mesentery, upward and to the left or downward and to the left into the true pelvis. It may pass directly downward under the cecum. It may pass to the right in front of or back of the cecum. It may occupy any one of the peri- cecal fossff (p. 1266), but most often enters the ileocecal fossa. When the cecum is mobile the appendix may be found almost anywhere within the abdomen. When the cecum is undescended, the appendix of course shares in the failure to descend, and may be below the gall-bladder or in front of the right kidney, and may pass in several directions—upward behind the cecum, to the left behind the ileum and mesentery; or downward and inward into the true pelvis. It varies from one-. FlG, 1055.—Arteries of the cecum and of the appendix venniformis and of the terminal porti( (Poirier and Charpj'.) half an inch to nine inches in length ( to cm.) its average being about three inches ( cm.). Its diameter is from one-eighth inch to one-quarter inch (3 to 6 mm.). The operating surgeon may occasionally fail to find an appendix buried in one of the cecal fossae, and may conclude that the diverticulum is absent. In rare instances the appendix has been found absent. It is retained in position by a fold of peritoneum derived from the left leaf of the mesentery, which forms a mesentery for it, and is called the mesoappendix (p. 1265 and Figs. 1007 and 1008). This fold, in the majority of cases, is more or less triangular in shape, and, as a r
