writer that had lost those five letters
He was unable to add 2 and 6, because
was unknown to him. When he tried
| to write out the word "six" he could
only get as far as the first two letters,
| inasmuch as x was forgotten,
Another interesting case was that Of
q banker of Frankfort, Germany. He
was a first-rate business man and pos
sessed O wonderful memory 1t was his
boast that he never forgot anything.
All of sudden his memory left him en-
| tirely He could not even remember the
street or the house he lived in Then 1t
was found that he had always depend
ed upon sight for remembering every
thing he was what psychologists term
"visualist' In some manner UNI
known his visual centers had become
impaired. To restore them again was
evidently impossible, and so he had to
begin to acquire a new memory by
means of hearing--that is to say, by
training the auditory centers,
People remember things in different
ways according to the habit Of the in
dividual. For example, you ask one
man when Columbus discovered Amer
lea, and he will reply 1892 promptly,
having q visual picture of the figures
forming that date in his mind, But
another person will recall the date not
In that manner at all, but by sound.
In the latter case 1T may be the centers
Of hearing that furnish the memory,
but 1t is more likely to be those of vocal
speech. The best spoilers are visual
lsts-they see mental pictures of the
words, spelling them by reading them
off as lf from q blackboard. Lots of
folks have no such pictures at all Most
of them seem to depend chiefly, If not
wholly, upon the habit Of using the let
tiers and syllables in certain forms in
speaking.
The part of the brain belonging to
and representing each sense-seeing,
hearing, or what not-seems to be a
complete little brain in itself The
banker of Frankfort lost the use of
his visual brain for purposes Of mem
Dry and was obliged to begin like a
child and train his auditory brain. The
orator, whose words pour out in an elo-
quent flood as II self-inspired, possesses
centers of vocal speech which are high
ly developed, constituting in themselves
a brain capable Of doing its own think
ing, as it were. This idea may ac-
count for instances of dual personality,
where a man suddenly loses all recollec-
ton Of his past and Is obliged to start
cut and make q new Individuality. We
all feel sometimes as IL there were two
of us instead of one, and the theory
above expressed would lead to the con-
clusion that each of us is several. DR..
Holmes once described the human mind
as perhaps an omnibus"
The most satisfactory evidence res
pecting the location of sense centers
and motor areas has been obtained by
renewing certain portions of the brain
of lower animals, in order to observe
what they would do without them. II
the part of the gray matter represent

the dog or monkey will be blind, though
it's eyes are not interfered with, The
same idea applies to the other senses.
Vision is located in the back part of the
human brain. Along the side. of the
brain above the ear runs nearly hori-
zontally the assure of Silvius. Not far
from the middle Of this fissure is the
center Of hearing. Close by is the CEN
ter of smell, and beneath and inside of
this fissure is taste. It is hardly nee
essary to explain that the two halves
of the brain are just alike, each sense
center and motor area on one side havv
ing its fellow on the other eide. But

body and vice versa.
The intelligence and moral perception
seem to be located chiefly in the front
part of the brain, behind the forehead. |
Here are the higher physical centers
If the physical structures representing
them suffer damage, alterations Of
character and intellect result When
parts Of these frontal lobes have been
removed, a dog lcses memory and vari-
Gus other faculties. Seeing food, the
animal does not recognize 1t, though
hungry; or perhaps it will run past it
and not turn to get it, because the rec

hearing and smell are not easily made |

good as can be obtained.
Underneath the brain of a human be- |
ing is a small secondary brain which |
is called the cerebellum. So well as
