The breeding OF The common eel is one
OF the interesting questions, settled BY
uUturcllsts within the last few years.
The young are not nc an ell.like, ana
were called Leptocephali, says Prof
Ray Lancaster until ten or twelve
years ago, when speclment in an
aquarium on the coast OF Brittany
gradually developed into q Conger eel
The first inference that the Leptocepha-
d We're abnormal eel progeny has now
been proved 10 be- erroneous the var
i0us kinds having been shown 10 be the
normal young OF the various cells. The
breeding place has been traced finally
TO the sea, where the eggs are laid and
Matched In depths as great as 500 faith
oms.
Restoration 10 life after hours Of APP
parent death Is now known TO be possl-

water or from sufi0catlng gases IN

LAborde. a French physician, has de-
vised a mechanical tongue tractor,
driven by an electric motor.
Leyden jar on a balance Is said
to become percepubly heavier on being
charged, and Duela, French
physicist, finds that the apparent
change IN weight Is smaller before
rain, thus making It possible to pre-
dict the weather by Leyden jar and
a balance.
One OF the most remarkable OF the
attempts az steam-engine Improvement
that have followed the advent OF the
steam turbine Is the "crankless" engine
Of Ljungstrom. a Swedish engineer In
this engine a pulley is mounted at one
end OF e SHAFT, and 70 the other end Is
attached a casting Ia the form Of four
radia, cylinders. These cylinders re-
y0lvlng with the shaft in q closed
chamber, Each cylinder Is fitted with
hollow cylinder piston. whose outer end
carries roller which Is pressed by
centrifugal force against stationary
elllpucal track formed by the outside
casing The steam supply comes
through q pipe entering the casing op-
p0slte the shaft and screwed TO the
supply pipe IS stationary valve.

In the center Of the rotating casting,
and having two long slots or ports
connecting with the supply pipe and
two connecting with an exhaust pipe.
Each OF the four cylinders has a SINH
lar long slot az Us inner end. As the
pistons, following the elliptlcal track.
move outward. steam enters through
the valve and syllnder ports. and Ii
passes out through the exhaust ports
Of the valve as the pistons are forced
Inward the rotation being kept up by
the side thrust Of the pistOns when
forced by the steam pressure against
the outward-going curves OF the track.
A governor Inside the pulley acts on
the steam supply. while moving a han
die quickly reyerses the engine by
changing the radial position Of the
value ports and permitting steam 20

are moving Inward This engine Is
comparable with the steam turbine IN
lts extraordinary power ana efficiency,
and Its small size.
How 10 account for the rays emitted
by radlun in the dark has been a puzzle
to physicIsts Tor 10 could not be sup
posed that any substance could emit

the problem now offered II scarcely less
bewildering. The quantity Of this
energy has been measured. and Bee
