The novel form of ncandescent
lamp devised by Gu. Petersen, of Chris
tiana, is claimed to YIELD a stronger
light than the Nernst lamp, with about
the same saving Of electric current. The
lighi-radiating material is small rod
instead OF thread that becomes a
conductor only when heated, and
around this Is wound thin metal wire
of good conductlvity. Rod and wire
are connected with the current con-
ductors by equalizng resisters. which
serve to heat the rod and increase the
current resistance. The current is most
ly taken up by the rod.
Recent products brought to the notice
of French engineers by NJ. Leon Appert
include glass stone, glass strengthened
by enclosed natalie network opaline
glass. and glass perforated to facili-
tate ventilation. The glass stone OF NJ
Garchey is produced by cooling below
fusion glass rich In lime, then heat
ing to 1900 &C.. compressed in hydraulic
&c presses, and annealing. The ma
terial Is adapted for paving bricks and
filing and the outside OF buildings. II
Is unalterable, remarkably hard and
durable, and much less fragile than
binary glass.
A unique condition exists at North
witch, in Cheshire, Eng. The pumping
Of brine from the salt beds under the

TO remedy this a special system OF
