To bring away a quantity of feces does not exhaust the purpose of the enema. The intestinal sewer requires further cleaning from end to end, and the external parts around the anus as well. By playing a jet of water on the external anal region you finish the enema and avoid the very uncleanly practice of using “toilet paper” as a means of external cleansing. It is strange that otherwise cleanly people are content with such uncleanly treatment of these parts. They imagine that “toilet paper” will effectually remove the excrement and its attending odors. They would not think it sufficient thus to clean their hands if soiled by excrementitious matter. It is the old story, “out of sight, out of mind,” and of letting any make-shift in such cases answer; but the spirit of cleanliness is abroad in the land, and the Silent Club of the Cleanly is being formed through just such agencies as the Internal Fountain Bath. Many have doubtless longed for a better practice but did not know what to do. The “toilet paper” habit will pass with the once-a-day habit of stooling, the constipation habit, and the physic habit, for all four are uncleanly in the extreme. _Durability._ The enameled metal reservoir and the metal and hard-rubber parts of the handle ought, with care, to last a lifetime; the soft-rubber tube, if properly cared for, will be of service for a long time. _External Anal Pressure._ This is of very important assistance in flushing the colon, as it aids in preventing the return of the injected water, and thereby promotes its conveyance along the colon until it arrives at the surgically famous vermiform appendix. It is not strange that both ends of the large intestine--the anus and rectum and the appendix region--have kept the surgeons busy, and I may add the undertaker likewise. These two ends are of extraordinary concern, because they manifest intense symptoms and pathological consequences. Modern medical practice is the heroic treatment of symptoms and consequences and not patient search for causes of disease and sensible treatment of it, as explained in my treatise dealing with “Intestinal Ills,” as well as in the present volume. _Water Pressure._ Two or three gallons of water, suspended at the usual height of enemata appliance, affords quite enough pressure, especially when the outlet and tubing are amply large. The shut-off on the rubber tube enables the user to gauge the flow of water to a nicety. _Time Required._
