The courses, from which I have selected twelve lectures for my present purpose, were designed for just such instruction as is recommended in this report. They were, I believe, the first to be given on these subjects in any medical school or college in this country. Necessarily they covered a wider range of topics than the lectures now published which more properly serve as an introduction to the general subject. Footnote 2: “The Birth of the Dream,” _The Independent_, Oct. 30, 1913. Footnote 3: A descriptive account of this case, written as a sort of autobiography by the subject herself, was published in the _Journal of Abnormal Psychology_ (Vol. 3, Nos. 4 & 5, 1908-1909) under the title “My Life as a Dissociated Personality.” This remarkable account includes an instructive description of the coconscious self of considerable value. Footnote 4: I divide the Subconscious into two parts, namely the Unconscious and the Coconscious. See preface and Lecture VIII. LECTURE II CONSERVATION OF FORGOTTEN EXPERIENCES OF NORMAL, ARTIFICIAL, AND PATHOLOGICAL LIFE I. Normal Life =Evidence obtained by the method of automatic writing.=—If we take a suitable subject, one in whom “_automatic writing_”[5] has been developed, and study the content of the script, we may find that to a large extent it contains references to, i.e., memories of, experiences which have long been forgotten by the subject and which cannot even by the stimulus of memoranda be voluntarily recalled. These experiences may be actions performed even as far back as _childhood_, _or_ passages read in books, or fragments of conversation, etc. Thus B. C. A., who suffers from an intense fear or phobia of cats, particularly _white_ cats, can recall no experience in her life which could have given rise to it. Yet when automatic writing is resorted to the hand writes a detailed account of a fright into which she was thrown, when she was only five or six years of age, by a white kitten which had a fit while she was playing with it. The writing also describes in minute detail the furnishings of the room where the episode occurred, the pattern of the carpet, the decorative designs of the window shades, the furniture, etc. As this observation is typical of many others, it may be well to dwell upon it long enough to describe it in some detail for the benefit of those who are not familiar with this class of phenomena.
