The Rectosigmoid Apparatus 43 motility is high in the hypersthenic, low-in the asthenic, intermediate in the sthenic.It may be physiological for the hyper-sthenic to defecate two or three times daily,while in the asthenic, the rate may benormally so slow as to permit an evacua-tion but once in two days. The intestinaltube of the sthenic and hypersthenic is welladapted to the high energy requirementsof individuals exhibiting this structural other hand, the condition known as diver-ticulosis occurs more frequently in hyper-sthenics and sthenics. William J. Mayo2 has made a very-careful study of the rectosigmoid appara-tus. He has shown that it consists of3)2 inches of the intestinal tract, whichincludes the terminal 2 inches of the sig-moid and the proximal iL> inches of therectum. It is the narrowest part of

On the contrary, the intestinal tubeof the asthenic with its atonic character,low position and slow rate of motility,places the asthenic individual at a dis-advantage in the machinery required forthe production of bodily energy. A predilection for the development ofcertain pathological conditions may beassociated with habitus, e.g., the asthenicis notably predisposed to colonic stasis andmore frequently presents the syndromewhich is usually termed autointoxication.Moreover, the pelvic colon, from its lowposition, is more likely to become involvedin pelvic inflammatory processes.
