The hands may be tied to keep them from the sexual organs, and the feet also may be tied so as to keep the thighs separated. The child too may be placed in a straight waistcoat fastened behind, which may force the arms to rest on the chest. Different apparatus has been contrived also to keep the thighs asunder. One is composed of thick pieces of cork which are attached to the inside of the thighs. Drawers opening behind are sometimes used: these serve to imprison the lower part of the trunk. A kind of truss is sometimes used to preserve the sexual parts from external contact. The principal piece of this is of metal, either silver or tin: for females its form is triangular, and for boys it represents a sort of mould, in which the penis and scrotum may be placed: the bandage is kept in place by springs, like those of herniary bandages. To add to the security of this apparatus it is sometimes applied to a dress which opens only behind. In young and feeble children these means are exceedingly efficacious, as experience has proved. The art of the onanist has even sometimes evaded these bandages. The following case occurred in the practice of Reveille Pariset; a little girl 7 years old, whose health failed every day having been detected in onanism, her mother instead of reproaching her, gave her to understand that it was the custom to apply a bandage to girls of her age. This bandage was fitted very accurately and attained the purpose desired; the health of the child being rapidly established. Soon however the symptoms reappeared and more violently than before. The bandage was examined and it was found to be undisturbed. She however was watched and it was found that she used a quill for the purposes of onanism, which she slipped in under the bandage. After this, the mother stayed with her daughter all the time, and by her vigilance the child was saved. These mechanical bandages have other inconveniences which limit their use. First they cannot be employed in boarding schools as they become the subject of remark; and then they keep up in the genital organs a constant heat, irritation and moisture. The edges of the principal piece also may cause deep excoriations. For all this, however they are often useful and ought not to be neglected. CHAPTER II. OF THE MODE OF REPAIRING THE INJURIES ARISING FROM VENEREAL EXCESSES. In therapeutics we proceed in two ways; sometimes tracing the symptoms to their cause, we attempt to destroy this cause in the organ in which it is situated, and sometimes we attend only to symptoms. The same plan is applicable to the abuses of the genital organs, which as we have already seen forms a real disease.
