Dr. Stevens, who has used the treatment upon himself and patients for over twenty years, says that it in no wise interferes in his case with the normal movement of the bowels. To test it in this respect he has frequently discontinued its use for a week, with the result of a regular movement, as soon as enough faecal matter had accumulated to demand it. He recommends flushing every two or three days as a preventive of disease. For over twenty years he has practiced flushing upon himself as a precaution, and, although now between seventy and eighty years old, since beginning its use he has never known a day of sickness. It is contended by some people, including a percentage of physicians (who should know better), that the frequent use of this treatment will so stretch the colon that it will remain permanently distended. This argument is so totally opposed to physiological law, to say nothing of experience and common sense, that it is almost laughable. The veriest tyro in the matter of exercise knows that exercise develops a muscle; that repeated flexion and extension of the arm, for instance, will strengthen the muscles of that limb, not cause them to lose their contractibility. All muscle fibres are alike in structure, except that some are voluntary, others involuntary, but that difference is simply due to the difference in the source of nerve supply. There is no reason that can be shown why the muscles of the colon should lose their elasticity through exercise in contra-distinction to all the other muscles of the body, since they are not subjected to any extraordinary strain, the extreme tension only lasting for a few seconds, while as soon as the water commences to escape, relaxation follows, and, in addition, heat acts as a stimulant. The objection does not even merit serious consideration. "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.
