It can easily be imagined that this remedy may have a very different effect from that proposed. Castigation, and also the denuding of the body, which is necessary, often have an effect on children, indicated by the erection of the penis. Young persons sometimes desire this punishment. The sensations caused by it have been so strong, as to be followed by an immediate emission. How many children have become addicted to onanism, in consequence of this imprudent punishment! how often has the fatal habit of onanism been encouraged by it! These consequences have been pointed out by many authors. Pic de la Mirandole, Rhodoginus, &c., have related instances of it. The following is from Serrurier. “One of my school-fellows,” says he, “found an indescribable pleasure in being whipped: he took every occasion to provoke the master, who never pardoned an offender, but had him scourged, by individuals to whom this duty was committed. This same school-fellow declared that he was sorry when the punishment was ended, because then the pollution was not complete. What has been the consequence of this horrid discovery. The unhappy person became addicted to onanism. Reduced to the lowest stage of consumption, in consequence of the habitual loss of semen, his death presents us a picture of depravity, and an instance of the danger to which one is exposed by this fatal passion.” Castigation is much more to be dreaded when practised by one of an opposite sex from that of the patient. Even young children notice this difference. Rousseau, describing the effect produced on him by being punished by Mademoiselle Lambercier, says, he was then eight years old, “For a long time she confined herself to threats, and the threat of punishment seemed very dreadful to me; but after it was performed, I found it less terrible than I expected; so much so, that it required all my natural sweetness to prevent me from seeking a return of the punishment, by averting it: for I found in the pain, and even in the shame, a mixture of sensuality which had left rather a desire, than a fear to be punished by the same hand. The same punishment from the hand of her brother would doubtless have been less agreeable.” Rousseau having exposed himself a second time to punishment, it was seen _by a certain sign_, that this chastisement did not produce the desired effect: he therefore escaped afterward. Thanks to his temperament, Rousseau did not contract, at that dangerous period, a habit which would have extinguished, at their source, those admirable faculties which were afterward developed. The importance of separating the sexes in schools can be seen from the preceding remarks: this is done in many institutions, and should be practised in all. The rod, too, should also be excluded from families, and physicians should explain to families the double danger of a loss of modesty, and of exciting the senses.
