POPULAR SCIENCE NOTES.

A Curious THEoRY.--In "Physical
Education DR.. Luther Quick argues
that by exercising certain muscles it is
possible to develop certain sections of
the brain. His argument has special
reference to feeble minded persons,
whose mental condition, in his opinion,
might be improved by the rirht Kind Of
muscular exercise.
ERRONEOUS IDEA CoxCERNING Noe,
TUENAL ANIMALS Nocturnal creatures,
says the independent, are generally sup
posed not to see we'll in the daylight, but
facts collected are gradually dispelling
the idea. 1t is well known that fclines
which see we'll by night, seem to be able
to see quite as well by day, and this is
being found true of many other creatures.
The bat sees admirably by daytime, as
any one can ascertain by threatening it
with a twig. The owl, also, has first
rate day sight. lNight-nying Lepidoptera,
when disturbed in their places of refuge
during the day, have no difficulty in see
ing at once where is the nearest and best
placesfor temporary refuge. These and
similar facts are being made use of by
those interested in the study of develop
ment. 1t might be assumed that all were
originally light-lovers, but protective
considerations, or better chances of getting
God, led to the development of the night
rowing disposition. The OWL for in
stance, is hated by all birds Where one
is discovered by other dayloving species
they subject it to the direst persecution.
Owls could scarcely live as Il day-loving
bird under the present order of things
1t would be driven from the earth; and.
surprising it took on gradually its thiev-
ing habits for a living, it has had to love
darkness rather than light because of
these evil deeds. At any rate, the naked
fact seems to be that Woodworking
creatures can generally see we'll ia the
daylight when they want to.
WoMEN's BRAINS. The microscope,
writes B. F. Underwood in the 7Wcntirh
Century, has transferred the conception
of degrees of intelligence from gross to
finer morphology. Mere brain weight
counts for nothing, except for the
crudest concentrations. OF more conse-
Quence are the relative quantities of
white and gray showers of minute tele-
graphy lines between brain parts, and
of equal, il not transcendent Importance,
the disposition and development of the
blood vessels. Also given two brains
exactly alike, a difference in the hearts
ability to supply blood to the brain will
determine intellect in one and stupidity
in the other. Intelligence depends more
upon the quantitive relating to tibres of
parts of the brain than upon weights,
and a 40-ounce brain may have a more
intricate microscopic development than
one that weighs 80 ounces. The normal
brain exists in ratios related to muscular
development, and the brain wcishing
methods fully demonstrate that woman is
the equal of man in this articular-that
is, in proportion to physical development
there is no difference in the associated
brain quantities in the sexes. New
avenues are opening up 70 women. and
decades change our views concerning
woman's capacities Let there be the
fullest chance for her development. She
cannot surpass in certain matters, but
let opportunity and not priori preju-
dice settle what she can and cannot do.
1t is Idle to fear that she will become
the intellectual and physical monster of
Bulwer's looming Race" There are
reasons that SGT limits for
both sexes.
