I take this opportunity of drawing attention to a method recommended by Fere for the cure of masturbation, which I have myself found of good use in several cases, but which appears to be almost entirely unknown. It is that the child addicted to masturbation during the night hours should be watched by a trustworthy person; every time the child puts its hand to its genital organs, or endeavours to stimulate these organs mechanically in some other way, the attendant must immediately intervene, and draw the hands from beneath the bed-clothing. This plan may be adopted whether the child masturbates while asleep or while awake. But good can be expected from the method above all in those cases in which the child masturbates during sleep, and in which it commonly wakes up directly it is interfered with. In most cases the children treated in this way soon give up the practice of masturbation, even though the evil is of long standing. But it will be advisable to continue to supervise the child for some time after a cure has apparently been effected, lest what may have become a nervous automatism should be resumed after a brief intermission. The chief difficulty in the practical application of this method lies in the choice of a trustworthy person to watch the child. As a rule, the mother will be the most suitable, but now and again we shall find a hired nurse to whom this extremely difficult task may safely be entrusted. In a number of cases with which I have had to deal, I have recommended the mother to undertake the duty herself, because she seemed to me the most trustworthy person available. But it is a very regrettable fact that many mothers are altogether unwilling to make the necessary sacrifice for their child's good; and most of them are quite ready to believe that some woman whom they can hire for a few shillings a night will perform the duty which they themselves as mothers have renounced. Such lack of proper feeling is especially common among those who belong to what are termed the upper classes of society--to the aristocracy whether of birth or of wealth--whereas among the middle classes I have found mothers far more ready to make the necessary sacrifices.
