apart from brilliance too splendid for
the space lighted, is not Objectionable.
Whether the electric light can be divided
and utilized for small areas remains to be
proved, which it is said Edison proposes
to do with his 1SO0-hght machine now
in process Of erection in the Exposition
building. Experience has shown beyond
doubt, that as regards purity of the
atmosphere the electric light has proved
itself the superior of gas, but the work
men at the royal arsenal, Woolwich,
England, have made several complaints
against it, some of which may probably
be met by an alteration Of the lanterns
used. They say that the deep shadows
which it throws upon parts of their work
necessitates many expedients to get rid
of them, which are troublesome. They
also complain that it deceives them in
the breadth of line, and that the bright
ness affects their eyes so that they can
not see well when they get to their own
homes and use ordinary lights, and that
the brightness of the light affects the
nerves of the eye.
The problem of safety remains also to
be solved. Four fires have already been
caused by electrical machines in the Ex-
position building; two by an electro
motor of M. Marcel Depez, whose con-
Quoting wires are not thick enough, one
caused by the lamps of the Brush Com
pany, and one by the Swan lamps of
have been due to accidental contact of
wires, but high resistance of thin con-
Quoting mediums
Strolling through the large building
which is filled with electrical machinery,
one is astonished at the number and va
riety of arts to which this force of nature
is already applied by man. Here are
street cars and railway carriages pro-
PEELED by electricity, there are sewing
machines, instruments for the cutting of
steel, and manufacture of the smallest
articles. Over yonder mighty machinery
is being whirled round with lightning let
down from heaven, while by my side the
telephone whispers by its aid the low
tones of the human voice Very inter-
estlng is the signal service representa-
ton, but that which attracted our curl
osity most, was
The Induction Balance Used to Local
ize the Bullet in the Body of
President Garfield.
1t has been stated by some journals that
the PoSt-nlorten1 examination has proved
that the diagnosis of Prof. Bell was in
adequate. But if the experiments were
correctly carried out there could be no
error. A telephone is connected with
primary and secondary coils of insulated
wire carefully balanced. If piece of
metal be placed inside one of the coils
the character of the induction is changed
in that, and the balance is DESTROYED, so
that noise is heard in the telephone
A remarkable illustration of the utility
OF the apparatus as means Of diagnosis
occurred to-day Mr.. Elisha Gray, an
American, whose name is well-known in
connection with the telephone and the
harmonic telegraph, was disbeliever in
the induction balance as surgical APP
pliance. He said to Professor Hughes
Thirty years ago, when working at
some metal work, filing of iron entered
my finger. The more l tried to extract
1T the deeper it went in. l believe it is
still there, and if your instrument is of
any value you ought to be able to tell me
in which finger it is Professor Hughes
tested Mr.. Gray's fingers, but none of
them gave any sound until he came to
the forefnger of the right hand, when
the balance of the coils was quite de-
stroyed and noise was given out. This
was the very finger in which the filing
was buried thirty years ago. 1t need
scarcely be said that the doubter was
completely convinced.
We cannot leave this storehouse of
electric wonders without strong impress
sion Of
The Upward Movement of Science.
Unconsciously to itself, science is. ascend
ing nearer and nearer to the ideal and
the spiritual. Science is every day, in
the progress it is making from steam to
electricity, leading humanity away from
the reverence of brute matter and the
excess of materialism. With the brain
of man evolving these marvels, and the
discovery of such ETHEREAL forces in the
universe, it is impossible to forget the
soul we bear within us, and deny the
Spirit who animates the universe. No
part Of human labor is lost. The divin-
ity is no more absent from the worlds
material progress-its science, It's art its
labor-than from its religion. If we
divide into divine and not divine, we
should deliver up the world to Maniche-
ism, and the Devil with reason would
