DUAL PERSONALITY.
RESIDUAL PHENOMENA OF THE MIND

OF the Sleeping Mind.
Evidence IL not wanting 10 show thai
what we call personality Is III 'Stremely
complex thing the sum of subsidiary per
sonalities which now shift and change
like the figures III Il Kaleidoscope, ana
again becoming sharply deiM"d under
some abnormal condition crystalline into
two or more distinct groups Of elements,
which alternately sleep and wake or
even coexist These complex elements
may be so unstable, the groups conpos-
ing them constantly brea.Iug up and
forming new combinations, that the idea
of multiple personality does not natural
" attach itself to them, It Ia only when
;hey become stable. ana especially when
each exhibits well dcHned conscious
ness that we begin to thlak Of such
thing. But besides the abnormal and
diseased conditions which cause such
separation or crystaization there are
other conditions IN which in appears
somewhat less distinctly To one class
Of these | desire to call attention very
briefy-to that embracing what may be
called cases OF residual personality.
Residual phenomena of all kinds are
particularly interesting and instructive,
especially those where the few things re-
manning in group after rAany have been
removed differ widely III their collective
properties from those that have been
taken away while these latter are not
IN any way dlstngUisilable from those
Of the sum Of both before the division
This is the case often with residual per
sonality. Nothing is more common than
for group Of elements Ill what we call
q person to be differentiated in one Of
various ways, leaving behind residual
group differing altogether III its charac-
teristics. though the differentiated group
represents to us and is considered TO
be Identical with the original person.
The commOnest method of such differ
antietioG = sleep The clements OF
sleep are, as il were, substracted from
the normal personality, but there IS
usually left behind very curious some
shing-illogical, credulous, fantastic
whose nightly experiences the whole re
united person recollects in the morning
that of the discontinued person. The
major part of the person being absorbed
IN mental processes of some sort, the re-
sidual person lives its own separate men
tai life, thin:s. feels and wills by itself,
and perhaps carries on Il train of proc
esses which is continuous with proceed
ing train carried on under similar cir,
cumstances the day before.
This residual person may act very
mechanically The reunited person may
fail to recOllect what it's acts or thoughts
were and be- surprised to find how it has
been making use Of his limbs while he
what he vainly regards IA the one IN
Rlterable ego--has been absorbed in
thought. But. on the other hand. it may
be perfectly conscious and may carry
IN an entirely different train Of thought
of it's own. Almost always. however, it
is eccentric and betrays n weakness at
one point or another
For instance. I. suburban resident.
whom we will call 4. Is accustomed on
landing at the New York side Of the
ferry to abandon the mechanical task of
walking to E!s Office entirely 10 his resid-
ual personality ana 10 gvr ~ the major
part of himself to Thought '4np two per
sonalities act often with reriect--a always
with neutrality-suspicious.. tne residual
person being quite equal u the low task
Of evading vehicles. steering clear of pass
ersby and turning the proper corners.
When the office Ia reached and the two
persons again become one It Is often Q
difficult task To re'Nemh,r any circum-
stances of the walk

supposed. intending to walk down Gin
