The Importance of designing fly

BILE resistance TO the air has been iats-
lly shown In tests at a Nurnberg cleo
! trio station, a fiywheel driven at 90
revolutions per minute by engines or
$50 horsepower was found TO require
about Is horsepower TO keep 1t IN mo-
ton. and this was reduced about -
horsepower by covering che channeied
arms with sheet iron. The saving OF
IL per cent of the power of the en-
gines was equivalent to about $40
yearly In another test the result was
even more surprising, and $50 horse
power engine showed saving Of 30

The biological stations of the 1sw
England coast have solved the p~rp-
lem of artificial lobster culture. Sev-
eral thousand of the young fry are put
into a cylindrical scrim bag about three
/ feet in diameter and four feet deep,
/ and the water in the submerged beg is
constantly agitated by dasher driven
by gasoline engine This prevents
/ the fry from smothering or devouring

the eggs the creatures are able to take
care of themselves. this stage being
Lreached by 16 TO more than 20 per cent
of the fry, although no previous ex-
pertinent had one per cent of survivors.
The fish hatcheries can now save the
lobster industry.
Snake venom, from which $4,000 peo-
pie die annually in India, is poisonous,
when injected into the veins. to all ami
mails except the snakes themselves
The bite of the cobra kills most ami
mails within two hours, but of 100 per-
sons bitten only % succumbed in less
than two hours, while p survived more
than "a hours. The poison is chemical

the process. The blood globules are
deformed and coagulation stops cir
culation. so that partial paralysis may
result when the venom has not been
sufficient to cause death. Injections of
chloride of lime tend to counterfeit the
effect But the one successful remedy
seems to be DR.. Calmettes serum, pre-
pared in graduated strengths by moe

cobra or other reptiles. and this is not

Burns from Roentgen rays. now rec
ognized as real effect. have some
curious features. DR.. E. A. Goldman.
citing nearly 200 cases, notes that the
burns resemble sunburn. but that they
may extend much deeper. the body be-
ing transparent TO these rays. The
burns do not usually appear immedi-
ateiy. most often developing in about
ten days, though sometimes delayed
for months. Some persons are very
others are not affected in
any way. Injury may be avoided by
a thin grounded sheet of
aluminium, by keeping the time
within safe limits, and it is concluded
hat an exposure of five minutes at
at twenty inches-can do no
harm Not least singular is the ap-
parent cumulative action, a number of
safe exposures of the SAME -
surface seeming to be as dangerous ayl
l single long exposure.
BY his discovery of the Secret OF
Afridi wax-cloth. Mr.. George Watt has
brought to notice an interesting indus
ry of India. This cloth is a kind of
'aised colored painting on cotton fab
les, and il has been made by the -af-i-
lis for many generations, but the ne
lium used has been mystery. 1t is
low shown that the medium, known as
oghan. is a peculiar product of the
affiower seed. Roghan is ttiek-jel-
y-like substance. prepared only at
'eshawar, and is obtained when the
ii pressed from the seed is boiled for
welve hours and then thrown hot into
hallow pans of cold water. Before use
