To transfer Photographic print tC
glass painting or for other purposes
separate the paper print from the
background by steaming it, dry
thoroughly, and, having given the
warmed glass an even coating OF
clean balsam or negative varnish,
place the face of the print on the sur.
face thus prepared. Smooth it out,
and let stand in cool place until the
varnish has hardened. Then apply
water. ana with soft piece of gum
rubber rub off the paper so as to leave
the Photographic image on the var
nished glass.
Some years ago Mr.. Pepper created
| some sensation by undertaking to
make sugar from old shirts. Sugar is
TOW manufactured in Germany from
Old rags. The rags are treated with
sulphuric acid, and converted into
deXtrine. This is treated with a milk
of lime. and is then subjected to new
bath of sulphuric acid, which con-
VertS it into glucose. The glucose OBJ
tanned by this process is identical with
that of commerce, and may be used in
the same way of CONNECTIONS, ices, etc.
When the manufacture has become
more abundant, the price will doubt
less be very small. 1t is known that
large number of substances are ca
pabIe Of transformation into glucose.
The ceiluloSe Of fbrous tisSueof wood,
treated with sulphuric acid, is changed
into deXtrine and glucose, and glucose
IS lnduStrlally produced from starch.
The jewelers. of Turkey, who are
mostly Armenians, are said to have a
singular method of ornamenting
Weaknesses, etc, with diamonds and
other precious stones, by simply glu-
ing or cementing them on. The stone
is set in gold or silver, and the lower
part of the metal made fiat, or 20 cor
respond with that part to which it is
to be affixed; it. is then warmed gent
ly, and the glue applied, which is SO
very strong that the parts thus &C.
mented never separate. This cement,
which will firmly unite bits OF glass,
and even polished steel, and may Of
course be applied to Il great variety OF
useful purposes, is thus made: Dis
solve five or six bits OF gum-mastic,
each the size of Il large pea,
in as much alcohol as will Suf-
fee to render it liquid; in another yes
sci dissolve as much isinglaSS-pre-
viously little s0ftened IN water;
though none of the water must be
used-in good brandy or rum as will
make a two-ounce pnial Of very
strong glue, adding two small bits of
gum-galbanum or ammOniacum, which
must be rubbed or ground until they
are dissolved; then mix the whole
with sufficient heat. Keep the glue
in phial closely stopped, and when 1t
is to be used, set the phial in boiling
water. To avoid the cracking of the
phial by exposure to such sudden
heat, use thin green glass phial, and
hold it to the steam for Il few seconds
before immersing il in the hot water.
