Frigotherapy is stated 20 be al
ready i'll vogue at several places
III Europe. The treatment con
SistS in standing the patient, well
protected with furs, in a freezing
box cooled to 2O0o or more below
zero, this daily cold bath being
continued ten minutes. The head
is allowed to protrude from the
box, as breathing of the intense
ly cold air would be dangerous.
The effect is to powerfully stimu
late the circulation, creating an
immediate and ravenouS appetite.
and tending to Danish dyspepsia
and various kidney and liver
diseases, as we'll as nervous eX-
haustion and its attendant melan-
cholN and depression. The whole
body is aroused to vigorous &C,

The theory that So-callcd dark
photographs are produced by the
action of hydrogen peroxide has
been sustained in an elaborate
series OF experiments at the Davv
Farady laboratory. London, 10y
Dr, W. J. Russell. lie has shown
that all the results produced upon
a Photographic plate by both
metals and organic substances
can be produced by hydrogen
peroxide: that this substance acts
through gelatinc. cclluloid, etc.
exactly like the metals, essential
oils, etc; and that the active
metals and other materials are
the ones capable of giving rise to
hydrogen peroxide by oxidation
in moist air.
y striking possible application
Of electric waves is pointed out
by Professor Lodge, who has no
ticed that these waves cause
drops of mercury and oil to unite,
thus overcoming a difficulty Of
certain metallurgical operations.
He thinks that Scotch mist could
be converted into rain by electric
rays which would precipitate most
fumes, but doubts if the effect
upon London foe would be en-
coura@ing.

tinguiShing burning petroleum.

and in IA limited space is thus
made to quench the flames upon

with little effect.
Mother Earth is known to be
in IA state OF nervous palpitation
and continual unrest that Il few
years ago would have been
thought incredible, even solid
England. where earthquakes are
practically never felt, giving in
strumental records of seventy or
more unielt earthquakes yearly.
Some shocks are found to set the
entire globe in trcmhle. Be
sides the strongly marked pulsa-
tons, the pendulum instruments
show daily movements and al
most unbroken tremOrS, the latter
unexplained, although Professor
Milne suggests that they can
hardly be surprising when it is
considered that an average Of one
earthquake every half hour is felt
somewhere, while many under the
sea and deep in the ground must
be unfclt. One Of the interest
ing, but not yet understood, dis
coverieS is that magnetic diStur-
Dances are noted at a few ObServ-
atOries at the time of earthquakes
or even Just before, a suggested
cause being the displacement of
magnetic. The scientific study
Of seiSmology has made rapid
strides in the much shaken lands
Of Japan and Italy, while the
new series of ObServatorieS in all
important countries is extending
the work over the world, giving
promise of results Of great prac-
teal as we'll as scientific value,
as i'll showing engineers safe
routes for submarine cables, in
explaining peturbations of the
magnetic needle, and in giving
an understanding of the varied
displacements of the earth's
crust.
