Inherited Passion.--It is important to inquire the cause of this precocity. Said a father of our acquaintance, when remonstrated with for encouraging his infant son in a ridiculous flirtation, "I did just so when I was of his age." In this case the cause was evident. The child was only acting out the disposition bequeathed him by his parent. How often do the secret follies of parents stand out in bold relief in their children. Such a legacy is nothing to be proud of. We again quote from Dr. Acton some observations on the causes of this disorder,--for a grave disorder it is,--as follows:-- "I should specify _hereditary_ predisposition as by no means the least common.... I believe that, as in body and mind, so also in the passions, the sins of the father are frequently visited on the children. No man or woman, I am sure, can have habitually indulged the sexual passions ... without, at least, running the risk of finding that a disposition to follow a similar career has been inherited by the offspring. It is in this way only that we can explain the early and apparently almost irresistible propensity in generation after generation indulging similar habits and feelings." Various Causes of Sexual Precocity.--Another very powerful predisposing cause of sexual precocity will be alluded to under the head of "Marital Excesses." The irritation caused by worms in the rectum, by local irritation or uncleanliness, or by irritation of the bladder, are exciting causes which are not infrequent. The latter cause is indicated by another symptom, the frequent wetting of the bed at night. Such a symptom doubly demands immediate attention. The juvenile parties so common now-a-days, at which little ones of both sexes, of ages varying from four or five years to ten or twelve, with wonderful precocity and truthfulness imitate the conduct of their elders at fashionable dinners, cannot be too much deprecated. Such associations of the sexes have a strong tendency to develop prematurely the distinctive peculiarities of the sexes. This is well evidenced by the fact that on such occasions one of the most common and popular entertainments is sham marriages. Parents greatly err in encouraging or allowing their children to engage in amusements of so dangerous a character. They are productive of no good, and are almost without exception productive of positive and serious injury. Modern modes of life, improper clothing, the forcing system of cramming in schools, the immodest example of older persons, and especially the irritating, stimulating articles of diet which are daily set before children, as well as older people, undoubtedly have a powerful influence in stimulating the development of the sexual passions. This subject is again referred to under the heading, "Chastity." Obscene books and papers, lewd pictures, and evil communications are telling causes which will be further noticed elsewhere.
