Note 99 — Chapter IX

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).
