"A Russian inventor has introduced
! most curious and ingenious anemo-
yraph or recording anemcmeter. =
which the same record indicates at tho
same time both the velocity and the
direction OF tho wind.
A new heat motor has lately been
Introduced which operates without
ralves or exhaust, using the same air
over and over again at each stroke.
and except for small amount Of leak

pie application OF heat and the cooling
medium.
A celluloid film for positives, which
gives the appearance Of q photograph
on ivory is now being manufactured.
One grade is delicate sea-shell pink.
another white. and the third closely
resembles ivory. After drying, the
positive prints are flowed with papy-
roline varnish. The pictures may be
produced either as vignettes or with
margin of clear 6lm.
Satisfactory tests have bcen n,ado

is made OF all colors. SO as to be used
as a substitute for paint, and is claimed
to render houses entirely freproof.
-Pasteur's system Of inoculation for

"A writer in Buenos Ayrcs journal
reports having examined the fiber
made from the reeds and rushes of tho

textiles manufactured therefrom to be
undistinguishablc 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.

pulp is also made by means Of newly
invented process from these reeds and
rushes.

The cement commonly employed
for fastening the tops on kerosene

on an iron core in the depositing bath.
