ROME. June 9.-Everybody knows that
white light can be dccomposed by prism
into the seven spectral colors and that
therefore 1t In not n simple color. For
some time spectrum analysis revealed
ouly the visible phenomenon of the dis
ISOLATION Of colors. Later the discovery
vas made that the seven radiations were
essentially characterized by their wave
length. namely by the number OF their
vibrations.
Infra-rod and ultraviolet rays were
subsequently detected and classified. Be-
yond the ultraviolet rays there IL an UNI
seen and unknown division of rays. and
at the other end of the spectrum. beyond
the lnfra-red division and after the cleo
ttomagnetic waves of Hertz. there Is still
another unseen ana unknown zone. All
phenomena, like electricity, magnetism.
color. light and perhaps gravitat!on. are
yIbratory phenomena, characterized by
periods, or in other terms, differing from
each other by their length of wave.
Purely Electric waves.
The results obtained BY me are In per-
Ret harmony with all the known rules
OF vibratory physics and thcy are the
CRITICALLY possible. They are the natural
development OF modern physical knowl-
edge and the logical completion Of pre-
ylous research work "F''-rays come
from the infra-rcd end of the spectrum,
they are close to Hertzian waves, and
hence purely electric waves with more or
less similar properties. AS, however, they
are nearer to luminous waves than the
HerlZian waves are, they approach the
former and sufficiently follow their rules.
This explains how | have been able to
reflect and concentrate 'I"-rays.
In 1889 the French physicist, Joubert,
happened to draw two keys out of HIS
pocket and on accidentally bringing them
together no was surprised to see that they
produced electric sparks. The reason for
this phenomenon was that an electric
machine was In action at the time in his
laboratory and that Hcrtzian waves
were being produced. The sparks OBJ
aimed from the keys were therefore n
pure case OF resonance. The results Of
my invention are based on methodlcal
researches and scientific experiments OF
many similar isolated phenomena. They
were predicted by Gustavc lie Bon some
years ago. lie said that when electric
rays could be controlled We would witness
phenomena OF Sucn greatness that our
mode OF lfn would be reVolutiouiZed.

This same process can be applied with
extreme precision to electromagnetic
