I may cite one other experiment dealing with the conservation of the details of a day’s experiences after the lapse of several months. The subject was a little girl who suffered from hysterical tics. Hoping to discover the exciting cause of her nervous disturbance, I put her into deep hypnosis, and evoked the memories of the events of the day on which her disease developed, _about six months previously_. It was astonishing to hear her recall a continuous series of precise thoughts and acts, many of them trivial, of the kind that would be transient and forgotten by anybody. She began with the events of the early morning, giving her own thoughts and acts; the remarks of her father and mother, describing exactly the location in the house at the time of each member of the family; her arrival at school; the several lessons of the day; the remarks of the teacher; the happenings during recess; her final entry into the laboratory; and the sudden onset of the tic. Everything was given in chronological order. The memories were vivid and, as they came up into her mind, were recognized as true recollections.[16] All this was forgotten when she was awake, that is to say, although conserved, it could not be reproduced. There was no way, of course, of determining the accuracy of these memories and, therefore, their correctness lacks scientific proof. On the other hand, the facts, which are in entire correspondence with similar results obtained under conditions where confirmation is possible, have value as cumulative evidence.[17] It is not difficult to arrange experiments which will test the accuracy with which the minute details of experiences may be conserved when reproduction is at fault. A simple test is to have a suitable subject endeavor to repeat _verbatim_ the contents of a letter written by him at some preceding time—one week, two weeks, a month, or more. Few people, of course, can do this. If, now, the subject is a suitable one for the abstraction or hypnotic method it may be that he will be able to reproduce by one or the other method the test letter, word for word; a comparison of the reproduction with the letter will, of course, determine the accuracy of the memory. In such an experiment I have succeeded in getting two subjects, Miss B.[18] and B. C. A., to repeat _verbatim_ the contents of fairly long letters, and this even, on certain occasions, when, on account of the subject being a dissociated personality, there was no recollection of the letter at all, not even that it had been written. Such minute reproduction affords further evidence that the conservation of experiences may be much more complete and exact than ordinary conscious memory would lead us to suppose.
