sake of quiet; the ticking of the small watch could not be heard even if it should remain on the night-table, and moreover we all know that the regular ticking of a clock is conducive to sleep rather than disturbing. She does admit that there is not the least probability that flowerpots and vases left in place might of their own accord fall and break during the night. She drops the pretense of quiet for the other practice of this sleep ritual. She seems on the contrary to release a source of disturbing noises by the demand that the door between her own room and that of her parents remain half open, and she insures this condition by placing various objects in front of the open door. The most important observances concern the bed itself. The large pillow at the head of the bed may not touch the wooden back of the bed. The small pillow for her head must lie on the large pillow to form a rhomb; she then places her head exactly upon the diagonal of the rhomb. Before covering herself, the featherbed must be shaken so that its foot end becomes quite flat, but she never omits to press this down and redistribute the thickness. Allow me to pass over the other trivial incidents of this ritual; they would teach us nothing new and cause too great digression from our purpose. Do not overlook, however, the fact that all this does not run its course quite smoothly. Everything is pervaded by the anxiety that things have not been done properly; they must be examined, repeated. Her doubts seize first on one, then on another precaution, and the result is that one or two hours elapse during which the girl cannot and the intimidated parents dare not sleep. These torments were not so easily analyzed as the compulsive act of our former patient. In the working out of the interpretations I had to hint and suggest to the girl, and was met on her part either by positive denial or mocking doubt. This first reaction of denial, however, was followed by a time when she occupied herself of her own accord with the possibilities that had been suggested, noted the associations they called out, produced reminiscences, and established connections, until through her own efforts she had reached and accepted all interpretations. In so far as she did this, she desisted as well from the performance of her compulsive rules, and even before the treatment had ended she had given up the entire ritual. You must also know that the nature of present-day analysis by no means enables us to follow out each individual symptom until its meaning becomes clear. Rather it is necessary to abandon a given theme again and again, yet with the certainty that we will be led back to it in some other connection. The interpretation of the symptoms in this case, which I am about to give you, is a synthesis of results, which, with the interruptions of other work, needed weeks and months for their compilation.
