The experiment of producing light from
household refuse, now being tried for the
first time at Shoreditch, a London suburb
will be watched with interest by the civil
lied world. The refuse is burned in twelve
Instructor cells, each having a crate area
or twenty-five square feet, and each pair
heating water tube boiler which works at
a pressure of 200 pounds. Suitable engines
use the steam for driving three high and
three loW-tensiOn electric generators The
Instructors are operated throughout the
tWenty-four hours, but the power il
chiefly required for light heat is stored
by day by warming water tc feed the boil
ers at night. The Instructors are designed
10 burn 10000 tons of refuse per annum IL
is estimated that this will furnish electric
light and power and warm baths for the
124,0 900 inhabitants of Shoreditch.
In his latest observations just commun-
Gated to the Berlin Academy, Prof Roent-
gen finds that the X-rays emanate from
the irradiated air in all directions, so that
if they were visible the appearance would
be that of room filled with smoke and
lighted up by d candle. When a plate i'm
pervious TO the rays is placed in front of
a huoreScent screen. the barium patinocv-
anlde still remains luminous. but the
nuorescence disappears when the screen is
surrounded by thin cylinder of lead. The
observation that the rays may be made Wis
ible presumably by causing tluorescence of
the retina, is confirmed. Our present know-
edge of X-rays may be summed up by saw
ing that the rays from a discharging ap-
paratus are a mixture varying in absorba-
bihty and intensity, that the composition
depends chiefly on the duration of the dis
charging current, that different bodies alb
sorb different kinds of rays and that the
X-rays are produced by the cathode rays
and the phenomena of both are probably
of the same nature.
The idea that the moon has an appre-
ciable action upon earthquakes and the
weather has been maintained for q quarter
of a century by NJ. De Parville, the French
physicist, who notes that the scientific
world is now beginning to recognize such
effects. Concerning the much discussed
question of the influence of the moon upon
vegetation, NJ. De Parville says: If we
must speak with a certain reserve of the
lunar influence on tree-groWth, we should
add that no one has shown that such intiu-
ence does not exist. NJ Rousset in
his critical study, calls to mind an expert
ment that | made a long time agO in the
tropics, by planting side by side ten seeds
in the Wane of the moon and ten others
at full moon. The plants sowed at new
moon grew notceably more rapidly than
those at full moon. l explained this phe-
nomenon by saying that the first appeared
just in time to profit by the moons light
while the others, after termination, We're
not exposed so long to the lunar rays.
The hypothesis may be good, but
perhaps it does not correspond to the
reality. Nevertheless. it is confirmed by
an observation of M Carbonnier, who has,
on his part, shown that at full moon con-
fervoid and cryptogamic vegetation is more
active than in other lunar periods. How
against the lunar influence are insufficient
to reverse the popular prejudice.
