_Irritation of the bladder_, producing incontinence of urine, is another enemy to chastity. It should receive prompt attention and treatment. In children, this irritability is indicated by wetting of the bed at night. In cases of this kind, allow the child little drink in the latter portion of the day. See that the bladder is emptied just before he goes to bed. Wake him once or twice during the night, and have him urinate. Use all possible means to remove the cause of irritation by giving him plenty of out-of-door exercise and a very simple, though nutritious, diet. Avoid meat, eggs, and condiments. Modern Modes of Life.--Aside from all of the causes already enumerated, there are many other conditions and circumstances, the result of modern habits of living, that tend directly toward the excitement of sensuality. Superheated rooms, sedentary employments, the development of the mental and nervous organizations at the expense of the muscular, the cramming system in schools, too long confinement of school-children in a sitting position, the allowance of too great freedom between the sexes in the young, the demoralizing influence of most varieties of public amusement, balls, church fairs, and other like influences too numerous to mention, all tend in the one direction, that of abnormal excitation and precocious development of the sexual functions. It is not an exaggeration to say that for one conforming to modern modes of living, eating, sleeping, and drinking, absolute chastity is next to an absolute impossibility. This would certainly be true without a special interposition of Providence; but Providence never works miracles to obviate the results of voluntary sin. CONTINENCE. Continence differs from chastity in being entire restraint from sexual indulgence under all circumstances, while chastity is only restraint from unlawful indulgence. As we have both physical and mental chastity, so continence should be both mental and physical. Many of the observations on the subject of "Chastity" apply with equal force to continence. The causes of incontinence are the same as those of unchastity. The same relation also exists between mental and physical continence as between mental and physical chastity. The subject of continence evidently has a somewhat wider scope than that of chastity, as generally understood; but as we have considered the latter subject so fully, we shall devote less space to this, leaving the reader to make the application of such preceding remarks as reason may suggest to him are equally appropriate here. Without stopping to consider the various circumstances under which absolute continence is expedient, or desirable, or morally required, we will proceed at once to examine the question, Is continence harmful?
