“It operates against peristalsis,” we are told. I deny it, for the energy evinced by the intestine in expelling the water is proof of increased peristaltic vigor, if it is proof of anything. And even if it did suspend peristalsis for a few minutes, is it not a fact that other natural functions can be suspended for a much longer period, only to be resumed with unabated vigor? Equally absurd, and destitute of foundation, in fact, is the objection frequently advanced that the washing of the interior surface of the colon is injurious; as it washes away the fluid that Nature secretes for the purpose of lubrication. Where, in the name of common sense, do they get their authority for such a statement? Do they not know that such a contention is in direct opposition to physiological law? Does bathing the external surface of the body prevent the further excretion of perspiration; or bathing the eyes destroy the functions of the Meibomian glands? Does the drinking of water prevent any further discharge of saliva into the mouth, or of gastric juice into the stomach? If the washing away of a secretion destroyed the power of the secreting gland, human existence would be brief indeed. The truth is, that not one in ten thousand has any practical knowledge of the subject. They may possess a smattering, and in the endeavor to make it show to advantage, they draw upon their imagination to supply the deficiency. On the other hand, I have been making this subject a constant study for the past twenty years, having had experience in thousands of cases, and, therefore, contend that my opinion is of more value than that of the average man--whether physician or layman--and is at least entitled to respectful consideration. Whether the practice of the treatment is to be persisted in will, of course, depend upon the nature and habits of the patient. If the pernicious habits that caused the trouble are not abandoned, a constant resort to the treatment will be necessary. If the patient is naturally of a costive habit, and has thoroughly weakened his intestines by a reckless and indiscriminate use of cathartics, it will require a long persistence in reformed habits before the weakened bowels will have gained sufficient strength to fulfil their functions normally. It is advisable for elderly people to use it more or less continuously throughout life, for with advancing years the bowels naturally become less active, and this simple process offers a valuable means of assistance to flagging nature at the cost of little, if any, exertion; in fact, after a little experience no more will be thought of using the “Cascade” than of taking a meal.
