PICTURES IN THE EYE
Dine OF THE MYSTERIES OF THAT
COMPLEX ORGAN. THE BRAIN. s
Theories a. to the Cause Of the Liv-
ing Colorcd Fnnciful and Chang
ing Images That Appear ON Lying
Down After an Exciting Day.


There are many who will not readily
understand what is meant by pictures
in the eye, unless 1t be the Imagination,
or minds eye" of Hamlet, for the
power of seeing them is not conferred
on all alike. Even those who have
seen them from time to time, and prob
ably given them little heed, may not
feel altogether sure about the matter
without word of explanation.
Lying in bed, after firing or excit-
ing day, with your eyes closed and
about to fall asleep, have you never
seen, apparently in the eyeball, spots
and streaks Of colored light, changing
their forms and shifting their places?
Have you never watched them passing
into complicated patterns, like those
of the Kaleidoscope, or into pretty
landscapes quite unknown to you, or
into strange faces, now and again
very beautiful or angelic, but often as
ugly and hideous as COLLINS from the
Internal regions, or, happy, into scenes
of action reminding you Of the drama,
but such as you never saw in real life
or upon any stagei These pictures are
more alive thai the Giving pictures"
of the music halls They have the hues
of life and art and rival the quick
Change artist in their protean trans
formations. The ;animatograph TINT
can initiate their ceaseless evolutis.s
without u hitch or tremor will be a
novelty and make the fortune of its In
ventor.
What IRE they? 1t is one of the mys-
teries of that marvellous nay, miracu-
lous- organ, the brain. We must dis
tinguish them from other mysteries of
the border land' which lies between
the adjoining states of wideawake and
sound asleep
They are not the images Of n reverie
or day dream. Whether we recall the
past In our waking hours or invent
new incidents like a novelist, we can
govern them to some extent and are
quite aware of their fanciful or mental
character. They are not hallucina-
ton in the proper sense Of the term.
We feel they are subjective, or within
us; we suppose them in the eye itself,
whereas we believe hallucination Is
objective, or without US. An appari-
ton or specter that we take for real
ity is halluclnation. The ghost of
Hamlet's father, witnessed by several
persons, and the spook of his distant
brother, seen by Lord Brougham, were
probably Authorizations Of "tele-
pathic' order. The picture Of Millais
where man starts up and sees a
luminous lady Mt the foot Of his bed
is case of Authorization. The dream
image" Of the undergraduate who
dreamed that he was chased by
green figure and, awakening, saw 1t in
his room was also q hallucinadon.
Pictures in the eye IRE more akin to
what are called "after images" A
gentleman "a doctor, If we are not
mistakenly. after fatiguing day, was
cheered by the sight of beefsteak for
his dinner, as he very well might, but
seemingly the steak made deep i'm
preston on his mind OF his digestion,
for while he was browsing with his
eyes closed after eating it, he saw 1t
again US wildly as before, and on
dropping asleep he saw it a third time
in his dream. 1t was doubtless SUBJ
stantial steak, not a ghost. and yet 1t
haunted him.
There is, of course. more than one
theory of these living pictures in the
eye or, as they are called in science,
"hypnogogic images" One is that they
are formed ON the retina of the eye
and confined to 1t. Another Is that
they are purely mental and formed
In the cortex or bark, so to speak, of
the cerebrum. AS often happens, the
truth appears to lie in combination
of both views. Recent observations Of
NJ. Yves Delage have put the question
to experimental proof. When we look
at bright body-for example, the sun
and shut our eyes we see colored
spot of light, and If we move the eye
up or down, to right or left, the spot
moves with 1t. The spot in fact. is
left by the image Of the sun upon the
retina and therefore moves with it.
Now, If the hypnogogic images are on
the retlna they will also move with the
eye, and this is what NJ. Delage has
found. Nevertheless the brain also
comes into play In forming them.
