Gently sailed for this country with full

Although glycerine was discovered
by Scheele in 1879, 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.
-Oleomargarine has received anoth-
er blow, thirty dealers in Philadelphia
having recently had warrants issued
against them for selling it under false
pretences. These numerous prosecu-
tions give oleomargarine bad name,
by connecting it with constant viola

From 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.
In Holyoke, Mass, paper is made
directly from logs of wood. A power
full machine takes in a poplar log at
one end and turns out paper at the
other. The monsters diet consists of
seven and half cords of wood per day

newspapers.

--Shoemaker's wax has been used
with success in Glasgow to illustrate
to the students of natural philosophy,
in a moGel, the flow Of glaciers. It is

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 sub
stance.
One of the silk-manufacturing firms
Of Lyons is introducing the production
Of Photographic impressions on stuffs.
They sent to recent meeting of the
Photographic Society several pieces of
silk with a variety Of Photographic
pictures printed thereon, including,
others, number of large me-
1allions representing pictures of the
Did masters. The length of the speci-
mems thus exhibited is stated as being
10 less than 1874 feet The process by
which they are produced is not given,
1ut it is believed that the prints are
made with salts of silver. F
-" Tanitep is a material made from
waste leather scraps, and is a hard,
ine- grained, jet black substance, which
nay be moulded under a high heat and
PRESSURE, and will receive a polish
,qual to that of the best WhitbY jet. 1t
vas invented as a substitute for vulcan-
te, and is used in the manufacture of
ii articles for which the latter sub
tance is suitable. A new application
5 its employment in making emery
wheels, to which it is found to be pecu-
iarly adapted.
Novel Mode of Bird Catching.-A ,
lew application of the Ruhmkortf coil,
ays Les Nondes, has been made in the
of Marseilles. Instead

Opper wire is wound around the trunk t

taft. When the tiockhas been attract

rents of a similar kind have also been /
lade by M. Dalmas upon the vines of I

royed the parasites and their eggs. s
The improved French method Of f
