SCIENTIFIC MISCELLANY.

The telemobiloscope. designed by
Dusseldorf inventor for enabling pilot
to detect a ship near at hand In a fog,
depends upon the fact that electric
waves are reflected when they strike
a metallic object. The apparatus con-
sists OF a long box or tube, pivoted at
one end and open at the other, contain
ing spark generator near the pivoted
end and two lenses for collecting the
electric waves into bundle. A suit
able motor turns the box horizontally
on the vertical pivot. As the box slight
ly inclined toward the water is swung
around, the electric waves are projected
outward, and II they strike an object
containing metal, they are reflected
back, acting upon a receiver similar to
that used In wireless telegraphy. This
receiver is Influenced only by return
waves. When a vessel Is discovered
the apparatus IL turned until the re-
Election Is strongest, when good es-
innate Of the distance can be made.

IL the interesting discovery of Matsurn,
Japanese Psychologist, who shows that
the hair--like the finger nails-grows
smaller In disease, and that the dura-
ton OF the malady may be estimated
from the length Of the thinner section
OF the hairs. The variations are most
striking in the coarse-haired races of
people.

Luminous electric radiators are
claimed by II. ], Dowsing. the British
electrician, to offer important advan-
tages. They can be taken from room
to room where needed. they can he
placed In the most effective positions,
the rays can be applied TO heating the
lower part Of the room or the part
where heat Is needed, the heat can be
turned on and of lnstantaneously,
there Is no combustion, and no special
ventilation is required. For cold days
or cold parts Of a room they are spe-
cially eoontmical. The ready efficiency
goes far to Offset the loss In convert
ing energy into electric current ami
then into heat and makes electricity
a competitor with gas for heating.
The production of coal ornaments Is
one OF Japans interesting industries
The hardest and best pieces Of coal are
carefully saved by the miners. and
these are cut into great variety OF
shapes, and mounted In rings, trlnkets
and chains, or used for the heads OF
canes and umbrellas, or for other nov
elites. A chain lately sold is OF solid
black coal, each link being perfectly
cut.

invention OF a Danish engineer, is IN
