A writer in the St. Louis Globe- Demo

time when the walls, ceilings and floors

A Vienna engineer has just taken out
a patent for new smoke.abating pro-
cess. By means of electricity he pro-
poses to condense the solid part of the.
smoke as it arises from the coal, the
carbon thus folmed falling back into the.
furnace. 49,
Professor eclerc maintains that odors
are due, not to the emanations, as such,
of so-called odoriferous bodies, but to
the vibratory movement among such:
emanations, due to processes of oxida-.
ton. Scent, on this theory, is analogous
to sound. - ~ {s
In drilling glass, stick piece Of stiff
clay or putty on the part where you
wish to make the hole. Make q hole in
the putty the size you want the hole,
reaching to the gass, of course. Into
this hole pour little molten lead, when,
unless it is very thick glass, the piece
will immt diately drop out. ~. W.

The remarkable substance known as

of every kind of manipulation, such g
