"A very interesting discovery is that
of Prof j. ]. Thomson of Cambridge.
A gold leaf eIectroscope is charged so
| that the leaves stand far apart. AT
a distance X-rays are directed toward
the electroscOpe, Whereupon the 1nSu-
| lated conductor discharges itself, as IS
seen by the collapse of the gold leaves.
Prof Thomson explains this result by
the startling suppositiOn that A-rays
cause the air to be a conductor so that
the electroscope discharges itself to
earth through the air.
Wireless biography is the develop
ment of a discovery made in Paris by
NJ. Ed Brandy in 1890 Mr.. Croft OF
Winchester College, England, worked
| with a Brandy tube, made by himself,
in the autumn of 1892. DR.. Dawson
Turner had previously repeated M.
| Branly's experiments in Edinburgh.
Mr.. Croft exhibited this form of other
radiation to the Physical Society of
London in 1898, whereby the notice of
DR.. Oliver Lodge was drawn to NJ
Branly's discovery. A remarkable Sc
ries of experiments by DR.. Lodge in
1894 brought the phenomenon into COM
mon knowledge in Europe. This led to
Marconfs clever use of the principle
in 1896.
An experiment of Nikola Tesla is
famous. Two metal plates electrically
excited are placed opposite to each
other; to this space there is new
state of electrical conditions-vacuum
tubes light up when placed anywhere
in this magic field without any con-
Quoting attachments. 1t is called an
alternating electrostatic field The
plates are charged with positive and
negative electricity alternately with
out discharging across the space, the
change taking place 100000 times in
second. At this high period the
plates are quite harmless to the touch.
The electricity in this experiment is
carried through several stages, where
the period of alienation is about 100,
900, the results from touching the wires
would be very serious.
"A prolonged study of cracks in
granite, to which his attention was
first directed in Spitzbergen, led Nor
denskiold to the belief that they must
penetrate to a depth of 30 to 40 meters
below sea-level and no further, since
there they would NEE twith system
of horizontal cracks. Water would
sink through the first set OF cracks
to that depth, and there would form a
constant source of supply. The theory
was proved correct by the diamond
drill. and from it wider consequences
| of geological import inevitably result.
| But the practical benefits, especially
| in the large granite areas of Sweden
| and Finland, are great, and at Nor
| denskiold's inStigation large numbers
| of bore-holes have been sunk, light
| houses on seagirt rocks furnished with
a never-failing spring, and factories
supplied with pure water, previously
obtainable only at great expense.
No amount of contemplation of the
beauttudes, human or divine will pre-
vent men who drink contaminated wa
! ter or milk from getting sick; and no
| fear of future punishments, which may
| be in the meantime atoned for, will
| much deter men from wasting their
| substance in riotous living, says the
| Baltimore Sun. The moral certainty of
| speedy and memorable earthly annihil-
| alton is alone adequate to bring man
into conformity with cosmic rules.
What binders the application to New
| York, Philadelphia and Chicago of as
effective health regulations as those
now applied to Havana? Nothing, APP
| rarently, except general apathy. A
| certain city of about a million inhabi-
| tants had, during one year, more than
six thousand cases of typhoid fever.
| The cost to the city of a single case
may be estimated as not less, on the
average, than a thousand dollars,
| making an aggregate cost to that CITY
| Tor one year of more than six million
| dollars. Such d waste of financial re-
| sour*3s ought to appeal to vested in
lerests and general apathy, even
| though they cannot be moved by high
| cr motives. Distinct advances have al
ready been made in the line of effec-
! tive domestic and public sanitation:
but the good work accomplished is in
intestinal in comparison with that
winch can be, and ought to be, done.

miles long had to be accurately To-

a few yards in front of them. The
