which the same record indicates at the
same time both the velocity and the
direction Of the wind.

introduced which operates wfthont
valves or exhaust, using the same air
over and over again at each stroke.

gives the appearance OF photograph

resembles ivory. After drying, the
positive prints are flowed with panv-

produced either as vignettes or with a
margin of clear film.
satisfactory tests have been made
OF the new liquid. pyrodene. which

-Pasteur's system OF incubation for
anthrax and splenstic apoplexy is be-
ing successfully introduced on large
scale IN New South Wales. The ex.
periments have been so successful that
many stock owners are anxious to have
their sheep vaccinated at once. Pas
tours agents offer to vaccinate sheen
at the rate OF six cents per head, of
which four cents is for Pasteur's ROYALTY.

"A writer in u Buenos Ayres journal
reports having examined the fiber
made from the reeds and PUSHES of the
lowlands OF the Parana. and finds the
textiles manufactured therefrom to be
undlstlnguishable from those made of
wool or silk. Blankets. heavy goods
for mems wear, lettings, and .'black
silk dress goods are among the ar
ticles produced from the fiber. and are
pronounced unrivaled for texture,
finish. color. and durability. Paper
pulp is also made by means of a newly
invented process from these reeds and
PUSHES.
"A new invention exhibited in Mex
leo is the photographing photophone.
by speaking in a photophone transmit
ter, which consists of highly
polished diaphragm, rejecting a ray
OF light. this ray is set into vibration
and photograph is made of it on a
travelling band Of paper. If the image
of this Photographic tracing is pro-
jected by means of an electric arc or
oxy-hydrogen light upon selenium
receiver, the original speech is then
| heard.

Steam pipes OF copper are now made
by electro deposition from sulphatt
of copper solution. The pipe is formed
on an iron core in the depositing bath
and the copper is pressed by moving
tool as it is deposited. By this opera
ton tibrous strength is given to tn,
crystalline copper. After the pipe il
thus formed it is subjected to hot steam
which expands the copper shell, o
