There Are Two Factors In the Prob
lem, an Inherited Tendency and
Constant Prncticc-Thc origin of
the Innate Proclivity.
That the great majority of persons
use the right hand with greater skill
than the left is doubtless due to two
influences an innate proclivity and
constant practice. The preference
shown by most infants at the age of
one year for the use of the right hand
proves that there is an inherited tend
ency. Further evidence of it is found
in the greater ease with which any ell
tirely new act is performed by the right
than by the left hand. Training, how
ever, is an important factor. A mature
person, having lost the right hand by
accident, can achieve wonders with
the other il he only exercises patience.
perseverance and Il strong will.
The more mysterious of the two fac
tors in this problem Is the inborn tend
ency. How did it arise? There are
exceptions to the rule. Perhaps two
out of every hundred babies are left
handed. But when you stop to think Of
it the natural inclination of the other
ninety-eight is remarkable. A great
many Psychologists have specialized in
regard to its cause without reaching
any conclusion upon which all could
agree
DR.. George NJ. Gould says in the
Popular Science Monthly that right
handedness is so thoroughly ingratiat-
ed in human nature that 1t must have
been partially developed in the savage
ancestors of the race. Primitive man,
in his opinion, must have felt II definite
need for the exercise of his right hand
in preference to his left, and that ne
cessity must have been recognized and
obeyed for long period continuously.
The impulse could not well have die
tated his habits in eating, for knives

modern gun had not been invented,
and writing was practically unknown.
Moreover, in such operations as chip
ping arrowheads, weaving baskets and
welding clubs, bows and arrows it
could not have mattered much which
hand was employed.
When warfare had been carried to
such Il stage OF advancement as to in
volve the use of shield, however, that
object was probably held on the left
side in order to protect the heart. Then
as a matter of convenience the right
arm was left free for the more active
function Of fighting with spear and
sword. and with habitual exercise

nomenon was a finer organization of
that particular center in the brain
which controlled these movements and
which was situated in the left half of
the organ. The brain is the real seat Of
all deSterity, and something takes
place there in correspondence with eN-
ternal efficiency. With an increased
use of the right hand, DR.. Gould thinks,
there must have been greater demands
upon the right eye, because vision must
| precede the, order to strike or to give
peaceful signals. In this way there
may have been developed keener
power of vision in the right eye than in
the left DR.. Gould assumes that there

people are right eyed" and that in their
brains the center of vision is on the
left side, in close proximity to that gov
erning the right arm.

process which was conducted in the

compelled to take sides in locating the
latter, and she placed it to the left of

choice was governed by the employ
ment of the right hand for giving sig
nails. So intimately related are the
functions of speech and vision and
the control of the muscular efforts with

| Before discussing the cause Of left
handedness DR.. Gould calls attention TO
the fact that with right handed people
the left hand is occasionally called up
on to perform task of greater impor-
tance than it's mate. In eating the
fork is used more than the knife. In

the bowling with the right. 1t is sug-
gested that some of these operations
may result from the superiority of the
right eye. Perhaps the latter can watch
and guide them better when they are
I performed with the left than with the
right hand.
Left handedness is considered by DR..
Gould an inheritance from ancestors,
savage or civilized, who We're obligcl
by some misfortune to abandon the use
of the right hand. An even more inilu-
entail injury, he thinks, would have
been as to the right eye. With the cul-
