The colon is closely related anatomically to the abdominal viscera, enclosing within its embrace the mesenteric vessels, which play an important rôle in the regulation of the circulation and general metabolism of the body. The hepatic, splenic, and sigmoid flexures and the transverse colon are in intimate relation with the liver, duodenum, kidneys and pelvic organs, therefore, it is evident that it is possible to influence these viscera more or less by the application of heat, cold, electricity and other physical stimuli through the colon. Close as the anatomic relationship is between the colon and the abdominal viscera, described above, the physiologic relations may be said to be still more intimate. This is evident from the serious disturbances that accompany diseases of the colon, and is clearly shown by general physiologic action resulting from certain therapeutic measures applied directly to the colon.
In discussing such treatment of the abdominal viscera
