Having given a I'VE per cent aqueous
solution of carbon bisulphide for the re-
lief of intestinal symptoms accom-
panying pneumonia, an italian physi-
clan was surprised by a remarkable
improvement IN the pneumonia Itself
Tried on four cases of uncomplicated
pneumonia, the remedy gave excellent
results, fever disappearing on the third
or fourth day, and expectoration being
slight. The volatile substance easily
absorbed by the blood is supposed to
paralyze the pneumococci and neu-
tralize their toxins.
A heating apparatus that is cheap
efficient, sanitary, and of light and or
namental construction Is claimed by
Prof. Junkers, Of Dessau, Germany, in
his novel gas stove for hanging on the

slsts simply of corrugated reflector

air which rires into series of fiat
tubes over the burners. becomes heat
ed and escapes into an external cas-

stove. One series OF openings in the
casing allows the heated air to rise
to the top of the room. another series

completely burned; the heat is used to
best advantage, the strong circulation

Using Konig's gas flame, which oscil'
lates In height with the vibrations OF
the gas container, he registers the
sound motion In smoke instead of by
photograph. The gas is passed through
n tube into capsule closed by men-
brane and having a suitable burner
tube, the capsule is placed on a box
with the membrane over circular
aperture, and vibrations are set up by
a tuning fork at one side of the boz
or by telephone membrane. y stril
OF paper is slowly wound from one roll
10 another Just above the flame. While
there is no vibration the paper Is
smoked a uniform gray color: but when
the tuning fork or telephone membrane
is made to act, the flame is rapidlS
oscillated and the smoked record is
broken up into a series of little tongues
pointing in the direction of the tape 5
motion. The tongues vary in size and
shane. Each vowel spoken into the
telephone gives a characteristic series
of vibrations, and words produce vary
ing combinations. A timing device
marking tenths of a second on the tape
Is to be added TO the apparatus,
