Until now. ! thought, left-handedness

ness" as applied to the senses-that is, If
there be not men who have a greater SEN
sibility on the left than the right side?
With this idea / instituted a kind OF
physiological surveillance over number
Of my friends and collea CUES, and over
some workmen.
AZ result I found that left-sidedness
is in much larger proportion than left
handedness. showing itself in no less than
26 per cent of normal people. The curious
fact appeared also that left-hanoed peo-

The proportion of sensitive left-sided peo-

very much more if one takes into ac-
count the sensibility to plan, which they
have more highly developed in the left
side and visual sharpness. which. accord

not only greater in them than in honest
men but is more accumulated in the left
eye than in the right. In lunatics, as IS
revealed by the researches of Tonnini and
Amadei. this sensitive left-si@e1ness s

then. that left handed people are more
numerous among criminals. and sensitive
left-sidede people among lunatics.
To understand the exact significance Of
these researches. it is necessary to know
that a greater tendency to asymmetry is
seen in the animal species thane arer they
approach man and the more perfect they
are According TO Livingstone. parrots
are left handed and so are wild ANNA s
Oions. etc.). Camerano found in decaroi
crustaceans the left tentacle stronger by
200 grams than the right. while Roret
Revue Scientihque, 1890 found in TWEEN
ty-seven anthropomorphous monkeys the
left shoulder heavier than the right. Paret
noted that in the new born the weight
of the members of either side of the BODY
is the same. the child using indiferently
one or the other; it is only two years If
age that it begins TO prefer the right; in
Riddle age the difference becomes really
acute. while, however. It lessons in old
age. Furthermore one notes that the
asymmetry increases in proportion as
the organs are noble. and mora SO the
more they are exercised; so il is natural
that in man one side of the body should
prevail over the other and especially in
the train. The reason why the right pre-
dominates In most cases. above all. in the
cXtremeties, principally in the arms. is
explained by the fact that the move
meEts of the limbs are under the supreme
erection of the brain. which. as we all
know, is one Of the highest organs. is the
least symmetrical. and is divided into two

nine and adults outnumbering children. |
Thus women and savage haces even !
when they are not properly left-handed. |
have certain gestures and movements
which are a species of left-handedness.
Delaunnay observed that the man holds
out the left arm which the woman takes
with the left. that the woman buttons
her clothes from right to left, while the
man does o from left to right and that |
women and children when they trace a
line or turn key for instance. initiate
the movement from right to left. while
the adult man does so always from left
