rived of
food became for a brief time subject to them. One was of a pleasure
party driven out to sea, and not being able to reach the coast till
nightfall, at a place where they got shelter but nothing to eat.
They were mentally at ease and conscious of safety, but all were
troubled with visions that were half dreams and half hallucinations.
The cases of visions following protracted wakefulness are well known,
and I have collected a few of them myself. I have already spoken of
the maddening effect of solitariness: its influence may be inferred
from the recognised advantages of social amusements in the treatment
of the insane. It follows that the spiritual discipline undergone
for purposes of self-control and self-mortification, have also the
incidental effect of producing visions. It is to be expected that
these should often bear a close relation to the prevalent subjects
of thought, and although they may be really no more than the
products of one portion of the brain, which another portion of the
same brain is engaged in contemplating, they often, through error,
receive a religious sanction. This is notably the case among
half-civilised races.

The number of great men who have been once, twice, or more frequently,
subject to hallucinations is considerable. A list, to which it would
be easy to make large additions, is given by Brierre de Boismont
(_Hallucinations_, etc., 1862), from whom I translate the following
account of the star of the first Napoleon, which he heard,
second-hand, from General Rapp:--

"In 1806 General Rapp, on his return from the siege of Dantzic,
having occasion to speak to the Emperor, entered his study without
being announced. He found him so absorbed that his entry was
unperceived. The General seeing the Emperor continue motionless,
thought he might be ill, and purposely made a noise. Napoleon
immediately roused himself, and without any preamble, seizing Rapp
by the arm, said to him, pointing to the sky, 'Look there, up there.'
The General remained silent, but on being asked a second time, he
answered that he perceived nothing. 'What!' replied the Emperor,
'you do not see it? It is my star, it is before you, brilliant;'
then animating by degrees, he cried out, 'it has never abandoned me,
I see it on all great occasions, it commands me to go forward, and
it is a constant sign of good fortune to me.'"

Napoleon was no doubt a consummate actor, ready and unscrupulous in
imposing on others, but
