GENERAL IRREGULARITIES.
Why the Human Family Il Right-Handet

The reason why men are as gener 4
rule right-handed is thus ingeniously
given: Primitive man, being by nature
a fighting animal, fought for the most
part at first with his great canine teeth,
his nails and his fists, till in process OF
time he added to these early and nat
ural weapons. the further persuasions
of a club or shillalah. He also fought,
as Darwin has conclusively shown, in
the main for the possession OF the fe-
males of his kind, against other mem
bers Of his own sex and species And
if you fight, you soon learn to protect
the most exposed and vulnerable por-
ton of your body. Or, if you don't nat
ural selection manages 1t for you, by
killing you off as an immediate conse-
ouence. To the boxer, wrestler or
hand hand comb atant, that most vul-
nerable portion is undoubtedly the
heart. A hard blow well delivered, on
the left breast will easily kill, or, at any
rate, stun even strong man. Hence,
from an early period, men have used
the right hand to fight with, and have
employed the left arm chiefly to cover
the heart and parry blow aimed at
that specially vulnerable region. And
when weapons of offense and defense
supersede mere fists and teeth, it is the
right hand that grasps the spear or
sword, while the left holds over the
heart for defense the shield or buckler.
From this simple origin, then, the
whole vast difference of right and left
in civilized life takes its beginning. At
first, no doubt, the superiority OF the
right hand was only felt in the manner
of fighting. But that alone gave it
distinct pull, and paved the way at
last for the supremacy elsewhere;
for when We Ipons came into use
the habitual employment OF the
right hand to grasp the spear, sword or
knife made the nerves or muscles OF the
right side far more obedient to the con-
troll of the will than those of the left.
The dexterity thus acquired by the
right-see how the word ''dexterity"
(from the Latin dexter, the right i'm
plies this fact-made it more natural
for the early hunter and artifcer to en-
ploy the same hand preferentially in the
manufacture of flint, hatchets, bows
and arrows, and all the other manifold
activities Of savage life. II was the
hand with which he grasped his weapon;
it was, therefore, the hand with which
he Clipped it, To the end, however,
the right hand remains, especially the
hand in which you hold your knife"
and that is how your own children to
this day decide the question, which is
which, when they begin TO know their
right hand from their left for practical
purposes.
Now man being right-handed, it would
naturally be supposed that he is also
right-legged, but this does not appear
to be the case. Standing and working
with his right hand, there is a tendency
to use the left leg for balance. Many
people find less exertion in going round
circles 10 the right than to the left
Pane paths are nearly always made for
running in circles to the right So the
majority Of movements are more readily
performed to the right, as dancing, run
ming, etc. The rule in walking is to
keep to the right, and this appears to
be almost universal. 1t is more natural
to bear TO the right. OF large num-
Der of people from the better educated
classes asked about the existence OF the
rule, only g. per cent Of males and SO
per cent. of the females were aware
of the rule. The large majority obey it
unconsciously in walking. Crowds tend
to bear to the right. The left leg being
the stronger, it is more readily brought
into action. Hence, soldiers start off
with the left foot. 1t is the foot which
is placed into the stirrup Of the saddle
or step of bicycle when mounting. So
the left is the foot wich man takes of
from in jumping. In the experiments
OF Mr.. G. H. Darwin, blindfolding boys
and telling them to walk straight, the
right-handed one divered to the right
and vice versa. From measurements OF

logs, in 54.2 per cent the left leg was the
