Cotton Waste Transformed Into Nitrate
of CslluIose--A New Dynamo.
An interesting discovery mas been
made by two young chemists of Lon
don which will doubtless have very
important bearing on the manufacture
of cotton, says London correspon-
dent of the New York Times. Cotton
waste is transformed by new process
into nitrate of cellulose, and cotton
fabrics can be covered with solu
ton of il which will add materially to
the weight, strength and value of the
material. Thin, lightweight fabrics
can be filed up with this preparation,
which costs little more than sizing and
fuller's earth. The cellulose thus pre-
pared is also applicable to many differ
ent purposes. The cost is very little
more than the raw material, being
cheap and the process of manufacture
Inexpensive.
Another invention of moment is one
which enables waste paper to be con-
verted into kegs, barrels and vessels
OF every description. In making kegs
and barrels ingenious machinery is EN-
ployed, which enables the manufac-
turer to turn them out with solid heads

mand for the product in the shape of
kegs and barrels for powder, us no
dampness can be contracted, since they
are water and damp proof.
The latest improvement in dynamos
is one which gives q continuous cur
rent without brushes and accumula
tors. Scientists were incrcdulous and
pronounced this impossible, but the
proof of the pudding is in the eating.
and the new dynamo gives a strong
and continuous current notwithstand-
ing it was declared an impossibility-
At least one of the first elec tricians of
England, who was IN unbelicver, now
certifies that the new dynamo is sue
cess.
Most important improvements have
been mnde by an Austrian long domi-
ciled in England in methods and appa-
ratus for distillation. A new ferment
has been discovered, and improve
mcnts have been made in distilling ap-
paratus and in mashing machinery and
appliances which promise to complete
ly revolutionize the manufacture of
spirits. The bye products which are
saved and utilized leave the spirits al
most free of cost. The still is n most
important invention, since il separates
the fusel oil and other products fro:..
the spirits in the process of distilla-
ton, giving in three separate receivers
the three distinct products, and, il re-
quired, by a simple change in the ap-
paratus, instead of getting high wines.
pure neutral spirits can be obtained.
thus obviating separate rectification to
produce refined alcohol. The ferment
is made fresh for each mash and there
results iuxuriant crop of yeast,
which is trcatod and sold to bakers
and for domestic purposes. This alone
is n source of large revenue to the dis
tillers, rs the yeast Is of q very superb
or quality and the demand for IL is
practically unlimited. The yield of
spirits is more than onc-fourth more
than by old processes. Green malt in
stead of dried malt is used, which is n
source of considerable economy. The
very bsst Irish and Scotch whisky is
produced and fifty per cent. raw maize
substituted for the matted oats hereto
fore used, which in itself effects n very
