An Illustrative Case.--A case in which the vice originated in this manner was recently under our observation. The patient was a man of considerable intellectual power and some culture, but showed unmistakable signs of his early indiscretion. He stated that although he mingled quite freely with other boys of his age, he obtained no knowledge of the habit from others. He often heard allusions which he did not understand, and of which he did not, fortunately, discover the meaning. But he was afflicted with congenital _phimosis_, the prepuce being so tight that retraction was impossible. This, together with urinal irritation,--which occasioned nocturnal incontinence of urine,--constipation, and highly seasoned food, produced so much local irritation as to occasion frequent erections, and an increased secretion. He soon noticed that there was an accumulation of hardened secretion beneath the foreskin, and in attempting to remove this, he accidentally provoked voluptuous sensations. He speedily abandoned himself to the habit, often repeating it several times a day. Beginning at the age of twelve years, he continued it for three or four years. Soon after acquiring the habit, he became aware of its tendencies, through reading books upon the subject, but he found himself so completely enslaved that abstinence seemed impossible. One resolution to reform after another was formed, only to be speedily broken. His unwholesome diet, habitual constipation, and especially the unfortunate organic difficulty in his genital organs, produced an almost constant priapism, which was only relieved, and then but temporarily, by the act of pollution. His sedentary habits increased the difficulty to an extreme degree. In the meantime, his constitution, naturally weak, was being gradually undermined. He suffered from constant headache, heart-burn, pains in the back and limbs, weakness, and lassitude. Yet he attributed none of these ailments to the true cause. After the lapse of three or four years thus spent, and after repeated ineffectual attempts, by a powerful effort of the will, by the aid of prayer, and by adopting a more wholesome diet, he succeeded in getting the mastery of his vice. But the local difficulties still continued in a great degree, and under particularly aggravating circumstances occasioned a relapse at long intervals. After a time, the local difficulties grew less and less, and enabled him to gain a complete victory over the habit, though the results of previous sin still remained, for which he desired treatment. This case will serve as a fair illustration of many of similar character, in which the child accidentally makes the discovery which leads him to work his own ruin.
