For twenty-five years the nature Of magnet
ism, problem scarcely less bewildering than
life itself, has been subject Of research by
Joannes Zacharias, the German engineer. He
has experimental patiently and in many ways
with magnetized and unmagnetized materials,
with ordinary and special magnets. and has con-
cluded that this singular force Is not stable
state Of matter, but-like light and heat-is
motion Of molecules. This he holds to be true
in the case of permanent magnets as well as
electromagnetic. Some of his results are quite
magical-as the rotating Of suspended steel
ball enclosed In glass tube by turning copper
BAH on the other side Of partition, or displacing
metallic balls By the heat Of lighted cigar or
even OF finger, or causing horseshoe magnets
to rotate non-magnetic disks like selenium or
magnesium.
The so-caIIed "Plesmic barometer"-the novel
instrument Of A. s. Davis-is mercurial ba-
rometer reduced almost to pocket size, and de-
gas is already compressed the less given addi-
tionaI pressure will reduce It's volume. It con-
sists Of q U-tube, with q seven-inch arm Of thick
glass and one-tenth inch bore and q somewhat
shorter closed arm of thin quill tubing, small
iron mercury-cistern being attached to the top
of the long arm. Resting horizontally, the tube
Is filled with air, the mercury being ct one side
OF the cistern. Placing the tube upright the
mercury descends the long arm to q varying dis

pressure is 90 inches, az inches Of the pressure

now rain-gauge records the drops made to
fall on a delicately -balanced lever. thus indi-
eating the rainfall for any minute as well as the
total in tho shower or storm.
Two electric circuits connected with the Paris
Observatory control fifteen standard clocks. but
the system is complicated and costly. The new
wireless distribution of correct time by NJ.
Bigourdan. the Observatory astronomer, is much
simpler. On opening contact every second. the
directing clock sends current into an induc-
ton coil. which has an oscillator contested with
an antenna few yards long. Receivers In diff
ferent parts of the city take the signals by
sound or on the tape Of a chronograph. Syste-
matte Interruptions of the second discharges
indicate the minute. With the somewhat crude
apparatus so far used, the time has been trans
mitted to a distance of mile and aquarter with
an error of only two or three hundredths of a
second and with more elaborate arrangement
it would be possible to charge the air with pull
sations that could be converted into time beats
by suitable receivers in any dwelling or any
apartment in Paris and its suburbs.

Red light was shown by Finsen. the Danish
physician, to have decided influence in fevers
of certain kind, especially In lessening suppera-
ton and other symptoms in smallpox. Carry
ing the experiments further, DR.. Goldman, Of
Vienna, recently vaccinated number of chill
dren in two groups, keeping one group In red
light with red bands over the wounds, and the
other group under the usual conditions. The
results have been surprising. The children ex-
posed to daylight had the usual swelling. infla-
nation. DR.. Goldman believes there was no
lessening of the preventive power of the vac
cinatfon.
0dors, either natural or artificial, are given to
flowers by French chemist. Fading flowers
are restored by immersion in weak solution of
chloride of ammonia. and are then sprayed with
artificial perfume. To reinforce natural odor,
the flower is placed in glass containing gly-
cerine, and enclosed in box through which is
sent current of carbonc acid gas charged with
the odor Of the flower.

Under the fierce rays of the summer sun, the
surface Of the earth becomes very hot at mid
day, but the soil conducts heat so slowly that at
depth of two feet the lowest temperature for
the twenty -four hours is not reached until about
noon. while the greatest heat is at midnight. A
few inches lower down the daily temperature is
practically uniform. These curious facts appear
from observations made at Juvisy, France, dur
ing the great heat of last July, when the daily
oscillation at the earth's surface was Sl.9O c.,
though it was only 1859 in the air. and at depth
Of ten inches 1t was but 35o, disappearing en-
tirely at 80 inches. The maximum temperature
was reached about l P. NJ. and at the surface at
ga. N. at depht of ten inches, and at Ia. NJ. at
twenty inches.

The coating on the scales of fish has been
studied by recent investigator. He attributes
the fishes agility of movement and sustained
life in water TO this substance, and has at last
produced composition identical with it. This
artificial coating is claimed to be moisture proof
and preservative; and when applied to ships
bottoms it keeps them free from barnacles, thus
tending to give increased speed.

The flavor of hens eggs is declared by an Eng
lish medical man to be very materially affected
by food. When the hens act as scavengers their
eggs are made unfit to eat, but diet of sun
flower seeds produces remarkably fine and sweet
eggs.
Analyses of 350samples of coal from A French,
Belgian, German and British mines have shown
NJ Sallard that good coal should contain about
20 per cent. of volatile matter and not more
than to per cent. of ash.
