SCIENCE AND INDUSTRY.

In both south and central India the
need of cheap power is specially felt
and in these portions of India are
some of the grandest falls in the en-
tire country. The falls OF the Himal'
ayas, in the northern part of India
could be utilized We're they not too far
from places where industries can be
profitably carried on.
In recent number of The Lancet,
DR.. Philip calls attention to the fact
that if small round pebble is carried
in the mouth, thirst disappears, and
Precipitation is diminished. The doc
tor states that he has gone as long as
eight and half hours in broiling
sun with nothing but dry biscuits and
cheese for lunch, and at the end of
that time was not particularly thirsty.
An aeronaut was recently poisoned
by hydrogen arsenide, which escaped
from the balloon. This shows the ne
cessity of purifying the hydrogen
used for balloon purposes. The balloon
was filled in the ordinary way and no.
thing peculiar in the odor of the gas
was noticed. A few hours afterward
the persons who assisted in the
operation were taken seriously i'll and
one of them died.
One of the interesting pieces of ap-
paratuS recently shown at the Royal
society soiree, at London, was clock
which was controlled from a distance
by means of wireless telegraphy.
The signals were transmitted by
Hertz waves. and there was a short
vertical wire coherer, relay, and
local battery, which worked the mech
anism of the clock. 1t was stated
dulum and this apparatus, all the
clocks in town would be kept alike
without the use of wires.
Actinium is the name given new
poles of an electromagnetic, with
whose coil telephone is connected,
and it is variably magnetized at differ
ent portions of it's length as the cur
rent is varied radioactive element of
the iron group discovered by A. De-
bierne in ptchblende. The substance
has now been sufficiently concentrated
to show that it's rays have the same
effect upon barium platinocyanide,
Photographic plates and magnetic
field as those of radium and polonium,
while it is evidently distinct from
those elements.
thority on the earthquakes so frequent
in that country, has ascertained that
in the case of the injury of two-story
buildings, the damage is confined in
most cases to the upper story. He
affixed horizontal pendelum seismo-
of the Engineering college at Toxic,
and on the ground below placed a
similar instrument. Records of a
number of earthquakes were obtained,
and it was found that if the duration
of the vibration of shock was com
NSuN, aboNc liill IL se-
conD, the motionwas practically the
same in both places: but if the vibra-
ton was of quick period. the mo-
ton of the top of the wall was about
twice as great as that of the ground.
A curious disease which is just now
attracting considerable attention
abroad is known as brass founders
ague. 1t attacks workers in brass,
stampers. metal polishers. etc. and
is said to most frequently occur in
young women and boys. Absorption
of the poison seems to take place
through two channels. the lungs and
the digestive tract: in the lungs by in.
nalation of brass dust with which the
air of the workroom Is always loaded,
and into the alimentary canal by the
eating of food with unwashed, BRASS
contaminated hands. The symptoms
are paleness. neuralgia. emaciation,
hacking cough, splitting blood. and a
presence of green line on the teeth,
or greenish colored Precipitation. A
constant metallic taste in the mouth is
often complained of. Brass is an all
10y of copper and zinc; and the for
mer of these is supposed to be chiefly
responsible for the disease. Plenty of
milk, personal cleanliness and WELL
ventilated workshops are said to be
prophylactics; phosphorus in small
doses is recommended as useful
drug.
