| While pieces of wrought iron have
been brazed together by melted spelter
or brass, it has been hitherto impossi-
BILE to unite cast iron because it's carbon
forms layer of graphite particles on
the surface. A new German process
claims to have overcome this difficulty.
Oxide of copper with borax or silicate
of soda are applied to the surfaces to
be united, and on heating the copper
gives up Its oxygen to the graphite,
(which is converted into carbonic oxide
gas and escapes in bubbles, metallic
copper being deposited on the iron.
Any oxide of iron formed is dissolved
by the borax The surfaces of iron,
thus freed from graphite, unite readily
with the spelter which is run into the.
joint before it cools.
The discovery of pure helium, says
Prof. Dewar, would bring the realiza-
ton of Lord Kelvin's idea that a tenn
perature within degrees of absolute
zero can be reached. Prof. Dewar longs
for some scientific millionaire to pro-
vide the funds-which might prove
startling in mountaineering for ex-
periments to produce pure helium

In the new wind recorder of the Az
ricultural College of Berlin two styles
record eight directions of the wind.
The movement of the vane is followed

platinum sector of 135 degrees, turning
on vertical axis over four platinum
contacts, each connected with an cleo
tro-magnet. The axis is Joined to one
pole Of an accumulation cell. The cleo
tro-nagnets are arranged in pairs,
with pendulum swinging in front of
each pair; and reflections Of pendulum
to left and right mark north and so1th
winds respectively; reflections of the
other indicate east and west winds.
while the combinations Of two sirnulta-
neous movements give intermediate d.
rections. Pens on the two penduluns
give the record on a moving paper tape
The record can be made continuous
but at Berlin twenty wind records an
hour are obtained by means of a relay
whose circuit is caused by clockwork TO
be energized every three minutes, the
tape being started at the same mo-
ment.
