[Sidenote: Low Seated Water Closets] High-seated water closets, so often found in institutions, hotels and private houses, often favor constipation, as they do not permit of the proper physiological attitude in defecation. They prevent the individual from exercising abdominal pressure so essential for this function. Such seats should be made much lower than they are, or the feet should rest on a foot stool, in order to attain the proper attitude for thorough emptying of the intestine. [Sidenote: Number of Defecations] Observations on the manlike apes show that they defecate three or four times a day. Few of the human family have such ideal movements. Millions are conscious of some shortcoming in this regard, and doubtless millions more suffer from some shortcomings of which they are not conscious. Many believe they have free movements when actually they are suffering from a sluggishness in the rectum and other parts of the lower intestine. A rectal examination often reveals unsuspected fecal residues. [Sidenote: Establishing Proper Habits] The natural instinct to defecate, like many other natural instincts, is usually deadened by failure to exercise it. Civilized life makes it inconvenient to follow this instinct as promptly as, for instance, a horse does. The impulse to go to stool, if neglected even five minutes, may disappear. There are few health measures more simple and effective than restoring the normal sensitiveness of this important impulse. It may require a few weeks of special care, during which cold water enemas at night, following evacuation by paraffin oil injection, may be needed. It would be an excellent rule to visit the closet immediately after the noon and evening meals, as faithfully as most people do after the morning meal, until the reflex is trained to act at those, the most natural, times for its action. Before leaving the subject of intestinal poisoning, we may here again mention the importance of avoiding the poisoning which comes from too much protein. This poisoning is probably due largely to the decomposition of protein in the colon. [Sidenote: Use of Sour Milk] One proposed method for reducing this decomposition of protein is through the use of sour milk. Lactic acid, the acid of sour milk, constitutes a medium in which putrefactive germs do not thrive. Hence, if sufficient sour-milk germs can be kept in the intestines to constantly manufacture lactic acid, putrefaction will be reduced. But, as Professor Rettger and others have shown, the mere swallowing of a little sour milk or of sour-milk tablets is seldom sufficient. The "good germs" swallowed die of starvation before they do much good. To keep them alive and enable them to multiply, we must feed them. The free use of milk and of milk sugar, a little raw starch, or partially cooked cereal such as Scotch brose (oatmeal cooked only ten minutes) will feed the germs. [Sidenote: Evidences of Injury]
