In his new method of operating on
the organs of the chest. Prof. Ernest
Sauerbruch, of the University of Mar
burg, 1ucloses part of the body IN
cabinet from which the air has been
partially withdrawn. The air IN the
lungs is lighter than that outside,
under normal conditions, aud when
increased pressure tends to hatten
them, with great risk of fatal col
lapse. by operating in partial
vacuum, added pressure is avoided.
The patient breathes the outer air as
usual, and there is no disturbance of
the ordinary balance between internal
and external pressure. The new plan
has been very successful in the twelve
cases in which it has been tried.
Magnetization proves to have
measurable effect on weight. The
influence has been tested at a number
of stations in the United States aud
Canada, the magnet being pointed in
various directions, and the special
balance used being free rom magnetic
material. When the south pole of the
magnet was to the north the weight
was about l part in 1000, 900 more
than when the position was reversed.
In regions Of magnetic disturbance
the difference was greater, and ex
ceeded l part in 100, 900. The increase
in weight on magnetizing a metal
seemed of the order of l part in
1000, 600. sEEa
The alpha particle of radioactive
matter travels about 3 inches accord
ing to Prof. Rutherford, its average
speed being 6.000 miles a second. Its
path is marked by extraordinary vio-
lence, and about 100, 600 molecules
are broken up, giving rise to much
heat, and producing positively and
negatively charged ions in the pro-
cess.

Z feet long, and 4 feet wide, weighing
$50 pounds. 1t has 40 glass discs,
each 40 inches in diameter, of which
20 .Ievolve while the others remain
stationary. 1t is driven by an cleo
trio motor of one-quarter horse
power, being first excited by small
auxiliary hand machine, and at full
speed may yield a spark 80 inches

The new steriIizing oven of M.
BerlioZ, Frenchman, is Designed for
treating books and other easily dam
aged articles that do not admit of
bnking in an ordinary oven for de-
stroyin disease germs. 1t has de-
vice for the evaporation of aldehydes,
and, at atmospheric pressure and be-
low boiling point, it completely
sterilizes such objects as closed books.

Red lights have been proven TO be

at 3 miles; l7.2 candle-power, at 5

A healthy, regularly formed brain
of "A ounces, scarcely half of the
normal average seems to have been
the smallest ever recorded for an
admit. 1t was recently found in
Daniel Ryan, New York coachman,
who died suddenly at the age of AZ.
The theory that some houses, or
some parts of town, may be cancer

evidence collected by DIR. Fillaissier,
