Artificial respiration in the apparently drown
Cd Is usually set up by nexion of the arms Oh
the PROSTATE patient. Seeking more POSITIVE
and better action. DR.. Eisenmenger, OF Szusz-
varos. Hungary, has developed the new plan
az alternately raising and depressing the abb
domeu. and believes that this is much more
objective method Of resuscitation. His simple
apparatus Is kind of cuirass, which is strapped
20 the body and made tight by an edge PAD, with
foot bellows for alternately comprising ana
exhaustfng the air. The abdomen promptly
responds to the pressure In the cuirass. and this
gives not only vigorous inspiration and expira-
ton but also gentle heart massage, the COM
bined action tending to give favorable results
even in desperate cases.

The permanent exhibition of accident proven
fling appliances at Charlottenburg is to be sup
ported by an annual grant of $1,000 marks. 1t
now contains us large machines with 800 smaller
appliances. and Is electric motors supply driv-
ing power. Accident preventing parts Of ma
are blue. Workmen's clothing. eye protectors,
safety catches, door locks and speed brakes are
shown, with safety devices for lathes, presses,
circular saws, etc. Safety scafolding is placed
on the grounds. while gallery gives lessons In
preventing industrial diseases.

Aluminium, cadmium, zinc, magnesium, etc.,
aRect the Photographic plate, through not
classed es radioactive. late remarkable OBJ
servation is that the electric spark sometimes
increases the effect. sometimes lessons 1t, while
this influence though so superficial that slight
sandpapering removes it-persists for months.
The physiological effects of feeble radioactive
ity have been subject of investigation by e. 3.
London. Using quarter of grain of radium,
he apulied this to the forearm for brief inter
walls. and obtained distinct reaction after
minimum exposure of IS seconds. He suspended
four grains of radium bromide in a cage about
Is inches long BY 10 wide and IL high. Three
rabbits confined in this cage showed richness OF
the ears after 16 days. while burns soon appeared
on the backs, and after IA month the Dacks ana
heads were denuded of fur and covered with
ulcers. Movements had become apathetic and
slow. the hind legs being partially paralyzed.
The eyesight was affected. and post-mortem
examination revealed changes and degenera-
tions in the muscles, liver spleen, kidneys ana
generative organs.

= The dark film sometimes found on the rocks
Of rivers has been studied by Cairo chemist at
the Niles First Cataract. 1t is concluded that
the film, like that Of desert rocks, arises from
material in the rocks themselves, and that the
depth of color, depends upon the amount of
black oxide of manganese contained although
silica tends to add to the darkening. The him
Is formed and preserved only in hot climates
having small rainfall.

Ordinary window glass passes nearly all of the
heat coming from the sun, althoughit intercepts
dark heat but the new glass of Richard Siz-
moudy an Austrian, is claimed to prevent the
passage Of nine tenths Of the heat of the suns
rays. This glass would change dollhouse into
q cold house. The advantages seem to be nu-
merous. but not least should be the delightful
GOODNESS of summer cottages having windows of
thenew material.
Instead of the long celluloid film, London
photographer uses circular glass plates for the
oinematograph. The pictures are taken in
spiral, and plate Is inches in diameter holds
several hundred. recording story lasting about
four minutes.
researches
In gases travel from one end of tube to the
other at g certain definite speed This has sug-
Rested an Important Improvement in the blow
nine. and ia the apparatus brought out by the
Societe e, Oxyhydyique of Paris the gases are
mixed before being brought to the flame, ex-
plosion in the tube being prevented by forcing
the mixture from the nozzle at speed greater
than the rate of propagation of the fame. The
blowpipe Is very simple. 1t is ordinary long
conical nozzle with two openings at the larger
end, rubber tube passing to each inlet from a
gas cylinder provided with valves and pressure
gauges combined with gas-expanders; but
MFre- form has mixing chamber with single
tube leading from it to the nozzle light
form, weighing half pound. uses hydrogen
land Oxygen, the acetylene model being heavier.
This blowpipe is especially useful for welding
tubes, pieces of STEEL boiler work, etc., ana IL
can also be applied to the cutting of metals.
With a device for moving and directing the
fame, a circular disc can be cut from an inch
thick steel plate at the rate of foot minute,
as q saw cuts soft plank, the cut being scarcely
thicker than that of saw. "A
In the latest fight against the rabbit pest In
Australia the attempt Is made to destroy the
animals in their burrows. Especially construc-
ted boiler is used. with length of flexible
metallic hose, and steam at high pressure is
forced into the burrow, after first closing all
openings except that for the hose. Theearly
results have been very encouraging.

Ordinary clothing, it is pointed out. keeps the
skin Of man in almost complete darkness. A
London physician advises that consumptives
wear white clothing. and that it be linen or cot
ton, never of silk Blue and violet pass the
higher rays fairly we'll, but red black, yellow
and green transmit little but heat rays.
