amperes and 90, 600 volts was required
to do this work in one second. Inn
represents about 1000 horse power
and taking the duration OF the llght
ming as one tenth of a second the tota
power would be 10 times as much.
How it is possible to measure vino
by its sound has been told by Prof Car
Barus to the National Academy OF
Sciences. The whistling of the wind
across a wire varies with the velocity,
and this can be computed from the
mitch of the note observed in case OF q
given diameter of wire and for given
air Temperature. A special micrometer
attachment can be made to convey the
sound. isolated from other noises, TO
the observer at distance. Every gust
and variation can be studied, and an
idea of the direction of the gust can be
| had from sounds from three wires
placed at right angles to one another.
Micro aulmometry Is the name pro
posed for observations by this method.
Suppurating wounds, ulcers, lupous
and tuherculous sores, have been treat
ed bv DIR. G.. Stoker with remarkable
results by surrounding them with an
atmosphere OF pure oxygen, by means
of rubber bags. Not only were old
sores rapidly healed, but pain was al
most Immediately alleviated.
The experiments of Lieut.. b. Baden
Powell with military kites have been
sufficiently encouraging to give interest
to the curious sugg estion IN aerial
navigation made by him to the British
association for the Advancement of
Science He pointed out that the
wind is nearly always stronger at an
elevation than near the earth, often
blowing at 1000 yards with three times
its velocity just above ground. He
proposes TO take advantage of this
difference by connecting two kites 10y
a long line and sending them up to
different heights, the weight carried |
being attached to the line near the |
lower kite. The lower kite would |
thus supply retafding medium to the
upper, the effect being the samc in
principle as if the upper kite were held
to the earth by a string and the lower
Kite were flowed through the air by
boy running with the string in his
land Both kites would be kept fy
ing, although not held to the earth 10y

quite possible that they might be nav
gated considerably ont of the winds 4;
