scious or
unconscious, or of confusion of memory, or the fact of the crystal
vision will be simply denied. Thus a vast number of well-
authenticated cases of veracious visions will be required before
science could admit that it might be well to investigate hitherto
unacknowledged faculties of the human mind. The evidence can never be
other than the word of the seer, with whatever value may attach to the
testimony of those for whom he "sees," and describes, persons and
places unknown to himself. The evidence of individuals as to their
own subjective experiences is accepted by psychologists in other
departments of the study. {66}

CHAPTER IV

Veracious Waking Hallucinations not recognised by Science; or
explained by Coincidence, Imposture, False Memory. A Veracious
Hallucination popularly called a Wraith or Ghost. Example of
Unveracious Hallucination. The Family Coach. Ghosts' Clothes and
other Properties and Practices; how explained. Case of Veracious
Hallucination. Riding Home from Mess. Another Case. The Bright
Scar. The Vision and the Portrait. Such Stories not usually
believed. Cases of Touch: The Restraining Hand. Of Hearing: The
Benedictine's Voices; The Voice in the Bath-room. Other "Warnings".
The Maoris. The Man at the Lift. Appearances Coincident with Death.
Others not Coincident with Anything.

In "crystal-gazing" anybody can make experiments for himself and among
such friends as he thinks he can trust. They are hallucinations
consciously sought for, and as far as possible, provoked or induced by
taking certain simple measures. Unsought, spontaneous waking
hallucinations, according to the result of Mr. Galton's researches,
though not nearly so common as dreams, are as much facts of _sane_
mental experience. Now every ghost or wraith is a hallucination. You
see your wife in the dining-room when she really is in the drawing-
room; you see your late great-great-grandfather anywhere. Neither
person is really present. The first appearance in popular language is
a "wraith"; the second is a "ghost" in ordinary speech. Both are
hallucinations.

So far Mr. Galton would go, but mark what follows! Everybody allows
the existence of dreams, but comparatively few believe in dream
stories of _veracious_ dreams. So every scientific man believes in
hallucinations, {68} but few believe in _veracious_ hallucinations. A
veracious hallucination is, for our purpose, one which communicates
