There are several postures in which an enema may be taken. For those physically able, the most convenient, cleanly, and comfortable manner in which the thrice-daily inner bath may be had is the usual upright position on a water-closet seat. For those not physically able to sit upright, or for those that are not up-to-date and still adhere to the use of the fountain or the bulb syringe, the best method is not the usual sitting position, but the recumbent one. They are advised to lie on the right side, or on the back with hips raised. As a rule, a water-closet room is too small for reclining purposes, and, besides, the necessary rubber sheet and toweling convenience may be absent. Another drawback to lying full length for the purpose of flushing the colon is that with short arms and the lack of _external anal pressure_ there is apt to be an escape of water and feces around the anal point, necessitating much cleansing, considerable annoyance from nasty odors, and an irritating waste of time. Various devices, advertised as great inventions, have been resorted to for the purpose of overcoming such malodorous and uncleanly incidents. Among them is one that may be described as a colon tube, ranging from nine to eighteen inches in length, which can be attached to a fountain or a bulb syringe. The tube is usually of flexible rubber, _colored red_ to hide as much as possible the cumulative evidence of saturated filth and bacterial poison, the presence of which a white tube would betray too readily. I fail to see the necessity of introducing a rubber canal of such length into an intestinal channel five feet long for the purpose of “cleansing” the latter. The project lacks common sense. What a ridiculous practice--to worm or bore a hole through the impacted feces as you work your tube upward, then to squirt a little water into the middle of things, or as near to the middle as you have managed to get with a tube that will persist in bending on itself, and then to withdraw it covered with liquid filth! What folly to put a canal _into_ a canal--the one inserted being one-fifth the length of the one to be cleansed! Is not the original physiological channel good enough to convey the antiseptic water or oil, or both? Why not have the rubber canal five or six feet long if _one_ foot is so essential?
