Footnote 4: This interpretation was fully established by a further observation. One day when the mother had been out for some hours she was greeted on her return by the information ‘Baby o-o-o-o’ which at first remained unintelligible. It soon proved that during his long lonely hours he had found a method of bringing about his own disappearance. He had discovered his reflection in the long mirror which nearly reached to the ground and had then crouched down in front of it, so that the reflection was ‘_fort_’. Footnote 5: When the child was five and three-quarter years old his mother died. Now, when she was really ‘gone’ (o-o-o), the boy showed no grief for her. A second child had, it is true, been born in the meantime and had aroused his strongest jealousy.
