BRIEF NOTES OF SCIENCE

The colors penetrating deepest are
the blues and the green's, the red being
cut off first.
The ancient Greek philosophers be-
lieved in many of the points of the
Darwin theory.
1t has been proved as the result of
experiments, that the circulation OF
the blood is affected by mu ic.
Negroes on sugar plantations are
said almost to live on sugar-came dur
ing the season, and to thrive on it.
No bird can fly backward without
turning. The dragon fly, however,
can accomplish this feat and outstrip
any swallow.
DR.. Arbu hnot SAID he had known
more than one instance OF irasclble
passions having been much subdued
by vegetable diet.
On the summit of Ben Lomond are
the smallest trees Ill Great Britain
They are dwarf willows, and when
mature are only about two inches in
height.
Experiments have proved that if
fish set much above or below their
accustomed phi in the sea they will
die from the change Of the pressure of
the water.
An English writer + calls the
curious fact that when red clover was
first grown in Australia it never seed
ed because the tongue of the native
bee was to short to reach the pollen.
The work Of fertiliziny red clover is
chiefly done by long-tongned humble
bee.
Some experiments for the explora-
ton of the upper air were recently
undertaken at Paris. A free balloon
carrying self-recordirg instruments,
attained an elevation Of 1920 feet,
or nearly nine and one-third miles,
and recorded temperature of 7G de-
grees Fahrenheit below zero.
Since the application of photography
to the stars the discovery of asteroids
has been very rapid, no less than one
hundred having been found between
February, 1892, and October, 1896.
Up to 1915 only four asteroids were
known. Since then not a year has
passed without the discovery of one or
more.
A new lamp shade, invented by A.
Won Koz!owski, says the Gewerbe
Zeitung Vienna, is made hollow, to be
filled With very dilute solutisn OF
sulphate Of copper with a slight ad-
dition of an This shade absorbs
the heat anu rejects the light, at the
same time giving it an agreeable color.
George Isaac, German sci.ntist,
and three assistants, were blown to
atoms by an explosion of acetylene gas
on Dec. II. 1t is said that he believ-
ed he had discovered a non-explosive
variety of acetylene, and that Emperor
v William had been attracted by his
experiments with the manufacture OF
the gas, and was soon to visit his
laboratory.
NJ. Moissan states in the Annales
de Chime ct de Physique that the
most stable compounds known to
science disappear in the electric fur
mace. They only exceptions are the
perfectly crystallized borides, silicides
and carbides discovered by him.
These, he thinks probable, are original
constituents of the globe and must
still exist in some of the stars.
The assertion comes for Germany
that the majority Of the people are
not only right-handed, but also right
sighted. BY this is meant that most
people see better with the right eye
than with the left, and habitually,
though unconsciously, employ it more.
Some persons, however, make greater
use of the left eye than of the right
and accordingly are said to b. "leit-
eyed"
