New York. March lo-The Electric
Review will publish tomorrow a conn
munication from Nikola Tesla, describ.
ing for the first time his very interest
ing experiments in photography, The
scientific world has been awaiting an
expression of opinion from Mr.. Tesla
who is known to have begun his eNperi-
irents within an hour after thu news
Of Prof. Rontgens discovery was
cabled to this country. In connection
with Mr.. Tesla's communication the
Electrical Review prints two remarka-
Bile photographs. One of these shows
the right shoulder o. a man taken
through his ,lothing, a plate Of glass
three sixteenths of an inch thick and
two inches of wood This photograph,
which was made at distance of four
feet from the source of the Y rays,
shows the ribs, shoulder bones and
bones of the upper arm. he other
Photograph shows a copper wire bent TO
form the word "Rontgen, ana was made
at a distance of eleven feet from the
wooden slide covering the sehsifized
plate.
Mr.. Tesla also states that the rarefae-
ton of the Crookes tubes in these ex-
periments may be increased hy eteetri-
cal means to any degree desirable, far
beyond that obtainable by mechanical
appliances. This method he describes.
and says, in regard TO the nature Of the
\ rays. 81 am getting more and more
convinced that we have to deal with 4
stream Of material particles, which
strike the sensitive plate with great
velocity. Taking as basis the estimate
of Lord Kelvin on the speed Of pro.
jected particles in Crooke's bulb, We
arrive easily by the employment Of
every high potentials, to speeds Of as
much as a hundred kilometers d sec
ond. Now, again, the old question
arises: Are the PARTICLES from the eiec-

acting in purely mechanical way, as
when a row of ivory balls is struck: So
far most of the phenomena indicate
that they are projected Though thS
walls of the bulb, Of whatever material it
may be and am seeking for still more
conclusive evidence in this direction.
