raphy is tho discovery Of mode Of
printing without the employment Of ink
orany rismont whatever. The process
was accidentally discovered by Mr..
Frieso.G Greeno, who was working in his
laboratory ondoavoring to porfoot (. a
process for the reproduction Of photo
graphs in natural colors. Tho process
as described in tho last number Of tho
American Press is intereating.

can be run, tho inventor claims, at a

Tho only radical departure is in the

coin on pieoe Of white paper which
was resting on q sheet of tin. Tho tin
plate happened to be connected with
the positive polo Of an electric battery,
and the coin ohanoed to bo touched BY

coin perfoot impression WAS found

The experiment was repeated again

an exact reproduction in every detail Of
the original printed in black. Por-
