EDlS0N'S LAST MARVEL.


Brilliancy from an Electric Machine.

Mr.. Edison SAYS that he has discovered
how to make electricity II cheap and
pracul able substitute for Illuminating
gas. Many scientific men have worked
asSiduouslv IN that direction, but with
little success. A powerful electric light
WAS the result of these experiments, but
the problem ot its division into many
small lights was Il puzllcr. irammc,
SicmCns, Brush, Wallace, and others
produced at most ten lights from
single machine but singh ono Of

mills, and workshops. 1t his been re-

has done within II few DAYS. His ex-

the frame are insulated from each other,

connected with each carbon,
