ton on digestion il causes dryness of
the mucous membranes, but this is re-
lieved by draughts of calculated water.
In external applications to ulcers and
wounds, the gas is used for several
hours at time, day and night, with a
steriliZed water dressing at other
times. The surrounding skin becomes
very dry, and lanolin is recommended
to prevent cracking.
Catechu, or clutch, has been adulter-
ated in Burma with thansha, an ex-
tract of the than tree. The adulterant
has been supposed to be a worthless
material, but recent investigation
shows that it contains a large pro-
portion of tannin, and it's production
for tanning purposes is likely to be-
come a legitimate and probably i'm
portant industry. An advantage or
thansha is that it lacks red and brown
coloring matters, being thus adapted
for making high-class leather.
One of the most striking-not to say
startling-of recent discoveries, Is that
of a slight loss of weight in certain
chemical reactions. But, instead of
proving the destructibility of matter,
a later view is that weight may vary
with physical and chemical conditions,
and that this may throw light on the

Osmium wires having been produced
by a process invented by Auer Won
Welsbach, such wires have been tried
in incandescent lamps. They are heat
ed by the passage of the electric cur
and as they stand high temperature
well, osu1ium being the most difficult
of all metals to fuse, lighting Is effect
ed with great economy. The current
is used at pressures of only % to 30
volts. Experiments have shown that
for the same candle-power the osmIum
lamps use only 40 per cent of the cur
rent of ordinary incandescent lamps
of the same voltage, and that when an
osmium lamp and a carbon filament
lamp consume the same energy, the
former gives three and one-half times
the candle-power of the latter. The
life of the osmium lamp may range
from 700 to 1900 hours
Dry heat is ingeniously applied to
the body by new apparatus OF DR..
Hugo Davidson. This is either a pill
low or a mattress of rubber cloth, 10
the under side of which is sewed rub
Der tubing at distances or one-half to
three fourth of an inch, the whole
being laid upon a suitable support COW
cred by a layer of asbestos. A stream
of hot water running through the
tubing maintains an even temperature
of any required degree. In the mat
tresS the tubing is so arranged that
either the lower or the upper extrem-
ity may be heated separately, and the
apparatus forms soft and comforta-
BILE couch. Besides other applications,
this offers a very convenient method
of inducing perspiration.
Electricity is reported to have prov
en- an effective remedy for frost-bite.
Circulation is set up and continues for
a considerable time after current has
been passed between poles applied to
opposite sides of an affected member,
but several applications may be nee
essary to complete the restorative
process. One who has thoroughly
tested the treatment claims that rea-
