"A purely chemical publication OF wa
ter has given excellent results to L. Al
lain, Of Marseilles. Iodine, which IS
powerful antiseptic, is added in the pro-
portion of 1 part to 100000, and in
most cases destroys all bacilli within a
quarter of an hour. The free iodine
IS then neutralized by sodium hyposul-
pbite The water is finally filtered
through charcoal and it is claimed to
come out limpid, colorless and tasteless.
Gums are botanical puzzle. DIR.
Greig Smith, of Sydney, has now shown
that some of them are due to bacteria
and he has isolated some of these-like
that of "Arabin and made them pro-
duce their gums in the laboratory. he
suggests that all other gums are bacter-
iaI products. and that the worlds sup
Div Of gum might be increased by judi
cious selection of susceptible trees.

Physicists recognize two KINDS OF rays
inhnitesimal PARTICLES. like the cathode
rays, and those explained as vibrations.
Rays OF the latter KIND nave Deen ar

Of vibration. Electrical vibrations num-

the usual alternating current, 10 $1,000
million per second, and wave-iengtn
of o.6 centimeter, as observed IN tiny

The electronscope OF Mr.. John Don,
Of Aberdeen, is a large glass cell in
which gold-leat electroscope is sus-
pended and through which air can De
drawn at the rate OF about NTH OF
cubic foot per hour 1t gives means
OF accurately measuring the eiectrinca-
ton OF the air-that IS, the num9er OF
electrons present-at any time. IL mas
shown that leakage from the charged
electroscope may be as rapid on a dry
day as on damp one, tnat II Is Hlarke9
that a sea-breeze changes the negative
charge to positive one, Eiectrincation
seems SO important to neaitn tnat we
may expect a new era III climate study.
