Little L’s mother left her husband and went to live with a very rich man. The child is the product of this concubinage. Some time after the death of her legal husband, the mother left the father of the child, deserted the child and married another man. The foundling has been since taken care of by a children’s aid society. The foster-mother, with whom the child has been living for the last six months, brought her to the author for examination, with the following history: Soon after Mrs. L. received the child she noticed that the same was suffering from hysterical attacks. It sometimes whined and cried for several days in succession. It was always very restless and fidgety, giving the impression as if it was suffering from chorea minor. It was frequently running to the water-closet without any apparent necessity. Mrs. L. went to the society to find out what was the matter with the child and was told there that the child has been a confirmed masturbator since she was two and a half years old. Two other families, to whom the child has been successively given for adoption, have returned her to the society on account of this perversity. She was also told that if she refused to keep the child, the society will have to send it to an insane asylum as the last resort. For this reason, Mrs. L., who in the meantime had become attached to the child, resolved to try to break up the bad habit before she adopted it. Mrs. L., who is a highly intelligent lady and seems to possess an unusual power of observation, describes the attacks as follows: The usual mode of the child’s practice is volvulam manibus permulcere. The acme of the attack is manifested by the rigidity of the entire body, by the panting respiration, the staring eyes, the immobile pupils, redness of face, perspiration and general excitement. After a short interval of exhaustion, she gives herself again to her favorite pastime. In this way the child jugiter stuprum manu faciebat, even in the presence of others. All punishments by Mrs. L. and in the institution, where her little hands were even burned with hot iron, were of no avail. When her hands were tied so that she could not use them, fricabat muliebria sitting on a chair, by violent circular motions of her pelvis, which simply frightened her foster-mother. When lying in bed the child crosses her legs and rubs the thighs violently against each other. When the child was asked how it happened to start the performance of such practices, it answered that it had been first taught by her unnatural mother ut tractaret matris muliebria stupri causa. Also the matron of a certain institution is said to have taken the child into a dark closet et adduxit puellam ad matronæ manustuprum. The truth of these assertions cannot be proven, but by some experimenting, undertaken with the child, it has been proven beyond the shadow of a doubt that some adult woman abusa est puella ad stuprum suum.
