A Partisan metallurgical engineer
claims to have perfected a process Of
welding copper to steel wire so as to
make non-corroslve coating Many
advantages, it is said, will result from
the uses of this new wire, such as high
bined with smaller surface exposed to
wind and sleet than would be the case
with iron wire of the same conductive
ty. This wire is especially useful over
long spans, as pole intervals may be
much greater when 1t is used.
Sir Norman Lockyer has recently an
nounced the discovery of the strongest
spark lines of sulphur in the spectrum
of the bright star Rigel. These lines
have not previously been traced in the
spectrum Of any celestial body. Ger
tain sulphur lines which behave in an
| abnormal manner in spark and vacuum
tube spectra are not found in the spec
trum of Rigel, but they do occur in
stars of the type of Bellatrx and Epsi-
Ion Orionis, which represent higher
stages Of temperture than do stars Of
the type Of Rlgel.
| The Electric Review considers that
the transatlantic cables are in no i'm
mediate danger from the competition
of wireless telegraphy. One of the
pressing problems which wireless ex-
perts must solve is the development of
commercially practicable electricity.
Until number OF stations can work
side by side without affecting one an
other the usefulness of the new sys-
TEN will be very limited. Until this
problem Is solved, and an equally good
transmission by day and night assured.
the wireless system will occupy a very
minor position.
A study Of the great collection Of
meteorites In the Natural History Mu-
scum of Vienna leads DR.. f. Berwerth
to the interesting conclusion that me-
teoritic iron, as it falls from the sky,
and the various steels produced in our
modern steel works are the results of
Essentially similar chemical and physl-
cal causes. One of the most striking
characteristics noted in meteoritic
iron is the presence of considerable
quantity of nickel. But the mechan-
ism, by means of which nature, oper-
ating in celestial space, has produced
what is virtually nickel steel, remains
TO be explained.
The Physiological Institute Of the
University of Utrecht possesses one Of
the most remarkable rooms in the
world, a chamber about seven and a
half feet square, which is said to be
absolutely noiseless, as far as the en-
trance of sounds from outside Is con-
cerned. 1t Is on the top story OF lab
oratory building, and is an inside room,
but is so arranged that it can be venti-
lated and inundated with sunshine. The
walls, floor and ceiling each consist Of
half dozen layers of different sub
stances, with air spaces and interstices
filled with sound-deadening materials
Some persons when In the room expert
ence peculiar sensation in the ears
While every effort has been made to
exclude sounds that are not wanted, Of
course the object of constructing this
singular room was to experiment with
phenomena connected with sound.
Some of the sounds employed are made
in the room itself; others are intro
duced from outside by means Of cop
per tube, which Is plugged with lead
when not in use.
