[Footnote 99: The question, which was worded as follows:--_Have you ever, when believing yourself to be completely awake, had a vivid impression of seeing, or being touched by a living being or inanimate object, or of hearing a voice, which impression, so far as you could discover, was not due to any external physical cause?_--was printed at the top of a schedule containing twenty-five spaces for the names and other particulars of those answering. Collectors were instructed not to _select_ those of whom the question was asked; and to record alike negative and affirmative answers. In the case of an affirmative answer being received, further particulars were sought. For a full discussion of the various sources of error incident to an inquiry of this nature, and the precautions taken to avoid them, and for details of the results obtained, the reader is referred to the Report of the Committee, presented in a condensed form to the Congress of Experimental Psychology which met in London in 1892, and to be published in full in the _Proc. S.P.R._, vol. x., part 26 (forthcoming).] [Footnote 100: There was ill-health alone in about 5 per cent., anxiety alone in about 11 per cent., and both ill-health and anxiety in about 1.7 per cent. of first-hand cases.] [Footnote 101: Hallucinations occurring in the ambiguous state between waking and sleeping are called by some writers _hypnagogic_. For the purposes of our investigation, coincident hallucinations occurring at times when it is doubtful whether the percipient is fully awake, _e.g._, when he is in bed, are termed "borderland." Their evidential value is, of course, somewhat less than that of hallucinations occurring when the percipient is unquestionably awake. (See cases 57, 59, 65, 66, etc.)] [Footnote 102: Including apparitions of persons not dead more than twelve hours, and not known by the percipient to be dead.] [Footnote 103: As opposed to "dream-illusions," which depend on various organic sensations, or on the stimulation of the external organs of sense. The distinction is made by Professor Sully, _loc. cit._, p. 139.] [Footnote 104: These figures do not include second-hand cases. There are besides 29 undated cases, most of which probably belong to the remote period. See column 1 of table on p. 218 (visual cases).] [Footnote 105: The calculation is based upon an analysis of the whole number of visual cases reported during the most recent month, which would indicate an annual rate of about 140. The figures for the most recent quarter indicate an annual rate of about 120.] [Footnote 106: A hallucination which _coincides_ with a death is defined, for the purposes of this inquiry, as a hallucination which occurs within twelve hours of the death.]
