Foreign scientists have discovered
minute diamonds in meteorites found in
Siberia.
Cable messages are sent from New
York to Liverpool not by the ordinary
method of dots and dashes, but by cleo
trio flashes.
Some electric railways will be laid
along the rivers of northern Russia,
where the extreme cold endures during
great part of the year.
The new apparatus for feeding the fires
of electric light plants does away entirely
with the necessity of handling coal after
it has been dumped in the fuel room.
To add to our knowledge of terrestrial
magnetism it is suggested that regular
magnetic observatories be established at
Cape of Good Hope and in South
America.
Miss Bruce, of New York city, has
given 5000 to the Astronomical OBJ
servatory of Harvard, to be devoted to
the purchase of telescope for celestial
photography.
1t has been satisfactorily demonstrated
that the arsenites are effective against the
codling moth, that in their use there is
no danger to the fruit of the tree upon
which they are used.
The opinion seems to be gaining
ground among scientific men, concerning
the formation of petroleum, that it is in
all cases due to the decomposition of
vegetable matter contained in the rocks
where it is produced.
The latest improvement in the manu-
facture of filaments for incandescent
lamps consists in heating them to high
temperature by burning fluid fuel in
suitable furnace, and at the conclusion OF
the operation raising the temperature to
still higher degree for short period by
the introduction of blast of oxygen.
Take two eggs Of equal size. Care
fully dissolve the shell of one with dilute
hydrochloric acid, and immerse it in pure
water. In the course of a day or two
enough water will pass through the out
side membrane to cause it to nearly double
its volume, as may be shown by COM
parison with the second egg, which is
used as a standard.
An instantaneous Photographic appara-
tus is proposed to take the place of the
Judge at the winning posts in race-courses.
It's value is seen in very close races, when
the Judges can not decide accurately, and
in what are called sdead heats" when
two or three horses appear to reach the
winning post at exactly the same time.
The photograph will show one of the
horses to be an inch or so ahead, and de-
eide in his favor.
In French medical paper Blanche
Howard, female doctor, gives statisti
cal proof that the mortality from dipth.
liberia is rapidly increasing. Twenty
years ago in France this mortality was
between thirty-six and forty-five deaths
in every 100, 200 inhabitants; now it
amounts to 10 to 120 in every 100, 900.
In England the deaths in every 100, 900
number twenty-five; in America, sixty
to ninety, and in Germany 140 to 1856.
The true scientific attitude of the day,
as expressed by the President of the
British Association, Professor Flower, is
"a suspended judgment. Professor
Flower indorses Sir John Lubbock's idea
that the field of inquiry is limitless, and
that there may be ''fifty other senses as
different from ours as sound is from sight
and even within the boundaries of ouI
own senses there may be endless sounds
which we cannot hear, and colors as diff
ferent as red from green, of which we
have no conception, These and thou
sand other questions remain for solution.
The familiar world which surrounds us
may be totally different place to other
animals. TO them it may be full of
music which we cannot hear, of color
which we cannot see, of sensations which
we cannot conceive"
