"A Russian inventor has introdue d
a most curious ana ingenious anemn-
graph or recording anememeter. Ia
which the same record indicates AT the
same time both the velocity and the
direction Of the wind.
A new heat motor has lately been
introduced which operates without
valves ar exhaust, using the same air
over and over again at each stroke.
and except for u small amount of leak

medium.
"A ctllulold dlm for positives. which
gives the appearance Of IA photograph
on ivory Is now being manufactured.
One grade is ii delicate sca-shell pink.
another white. and the third closely
resembles ivory. After drying. the
positive prints are flowed with papy.
roline yarnish. The pictures may be

margin If clear film.
