4 The Laplanders, although small in
stature, have very largo skulls.
Resin, as used in building paper, is
being largely replaced by petroleum
product called ''stiIl wax" or wax
tailings.
The northern hemispheres contain
fourteen per cent. of the cold regions,
thirty-fve per cent. of the temperate
and tifty-one per cent. of the hot.
In paper on Earthquake Sounds"
Professor Milne suggests that there is a
4 close connection between the sounds
\ that precede the shock and the smaller
vibrations that bear like relation to
them.
Professor Daniel Kirkwood points out
that seven of the twenty known comets
OF short period have disappeared, either
by breaking into fragments, like Bield's
comet, or by tho transformation of the
orbit.
Sable Island, in the north Atlantic, is
fast disappearing. Some years ago it
was forty miles long by two and quar-
ter wide, but it has shrulk to nineteen
and half miles in length and less than
one in width.
Waters which circulate or stand in
leaden pipes or vessels, not only take
mp particles of lead through mechanical
action duo to friction, bus attack the
metal, the result of this being generally
\ lead carbonate.
j An instrument called the phonozoao-
u graph is intended by the Due do Feltre to
indicate the direction of any distant
sound. A microphonic plato OF peculiar
construction is moved about until the
y maximum effect is obtained.
The surface of the Mediterranean has
been found by accurate measurement to
lea little below that of the ocean, it
resembling somewhat a shallow funnel
with greatest depth coinciding with
I tho region where the water is most salt.
Il In paper recently read before one of
the English associations of engineers,
] the writer asserted that, according to
+ the present methods of dealing with
the motive power of the steam engine,
{ only some 20 per cent. was made avail
able, 50 per cent. of the energy de-
veloped in the furnace being thrown
sway.
In recent lecture, Mr. J. Hutchin-
y son expressed the belief that arsenic
may produce cancer. It's effect upon
/ the skin is most marked, but it may
i spoil the complexion Instead of improv-
I ing it, by making it muddy and I'M
/ slightly. 1t may also cause soft corns to
/ grow on the palms of the hands and
+ soles of the feet.
While tho most rapid cannon shots
scarcely attain velocity of 600 yards
second, over 1900 knots per hour me.
teorites are known to penetrate the air
with a velocity OF 40 900 or even Co.
600 yards per second, a velocity which
raises the air at once to temperature
of 1000 or 5000 centigrade.
The reported discovery of the "clixir
/ of life in baths of acetic acid, applied
/ daily, has elected some interesting sci
entitic comments. These demonstrate
the biological impossibility of living
forever, and show that Scottish physi.
clans have used acotic acid since 1850
/ for dissolvipg away dead tissue from
diseased joints, ETC., and have thus eff
fected some remarkable cures.
For quick filter take a clear piece
of chamois skin, free from th1a places,
cut it Of tho deIired length, wash in
b weak solution Of sal sofa or any al
kali to remove tho grease, a1d rinse
thoroughly in cold water before using.
Tinctures elixirs, sirups, and even mu-
cilages are, says writer in Drugg lists
Circular, filtered rapidly. A pint of the
thickest strip will run through in four
or five minutes. BY washing thorough
~ after each time of using it will last a
long time.
