The superiority Of American work

engineer, resident in Japan, has re-
Gently sailed for this country with full

Although glycerine was discovered
by Scheele in 1779, it is only within the
last few years that it has been manu-
factured commercially. Its value be-
came known simultaneously with easy
and cheap manufacture. France is
now pre-eminent in its production.
Prom some recent experiments it
Is considered desirable to make tele-
graph wire Of an alloy of aluminium
and iron. While the wire can be made
much smaller than the present gauge,
it will be stronger, of less susceptible
ty to atmospheric changes, and of
much greater conductivity than the
ordinary wire.
I'm Holyoke. Mass, paper is made

-Shoemaker's wax has been used
with success in Glasgow to illustrate
to the students of natural philosophy,
in Q moeel, the flow of glaciers. It is
wonderful how closely the flow of this
wax resembles that of ice. Sir w.
Thomson has also employed this sort
of wax to show the motion of lighter
bodies like cork, and heavier bodies
like bullets, through a viscous SUBJ
stance.
-"Tanite" is q material made from
waste leather scraps, and is q hard,
fine grained, jet black substance, which
may be moulded under high heat and
pressure, and will receive a polish
equal to that of the best Whitby Jet. 1t
was invented as substitute for vulcan
ite, and is used in the manufacture OF
all articles for which the latter sub
stance is suitable. A new application
is its employment in making emery
wheels, to which it is found to be pecu-
liarly adapted.
One of the silk-manufacturing firms
of Lyons is introducing the production
of Photographic impressions on stuffs.
They sent to q recent meeting of the
photographic Society several pieces OF
silk with variety of Photographic
pictures printed thereon, including.
among others, q number of large me-
dallions representing pictures of the
old masters. The length Of the speci-
mems thus exhibited is stated as being
no less than 1S4 feet. The process by
which they are produced is not given,
but it is believed that the prints are
made with salts Of silver.
