The Cathode Stream Within a Bulb

as commonly caiied-which have astanished
the world by bringing light out OF dark
places, even Illuminating the human body,
are now declared to lie material particles by
no less an authority than Nikola Tesla.
Mr.. Tesla has been led to take this view
Tor some time from the results of expert
men,s which n. has been conducting in his
laboratory. But now he comes forward
without hesitation and says that the elcc-
tricai conditions within thetube from which

They are material as cannon balls; infini-
tesip:ai and attenuated, Ii is true, but actual
material which bomhard the glass and any
object which may come in line with their
motion. And this motion is 10 insignificant
thing, and would max ethe most ra:id NOV
ing cannon hall appear to stand still for Mr
Tesla. says his experiments show them to
n,oveat velocity OF not less than sixty-two
niles second. IN the measurements he
uses he calls il" 100 kiiometers a second"
Mr.. Tesla further sd IS he can feel the ef-
sects OF these particles striking gainst his
eye, and has noted the sensation pr .siuced
when they come in contact with his brain
MIR TESLA s DECL ARATION.
Mr.. Tesla MA kes public his conclusions in
relation to the RoentSen rays in a letter,
in which after referring 10 Prof Rent-
gems theory that the rays were iongituL-
iBal waves OF ether ne says:
AFTER long and careful investigation
with apparatus eSceIleutly suited for the
purpose, capable of producing Impressions
at great distances, and i fterexanuing the
the results pointed out by other expert
nirnters, / have come TO the conclusion,
which Inow lind coura ge tOproB"unce with
out hesitation, that I Ec original hypotnesis
of Roent gen will be confirmed In two par
ticuiars first, in regard to the Longitudinal
character of the disturbances; scannd, In

propa CATION.
There is but little doubt at present thata
catholic stream within a bulb is composed
OF sinailparticles of matter, thrown off with
great velocity from the electrnde. The
velocity probably attained is cstimable, and
fully accountable for the mechanical aud
heating effects produced by the impact
against the wall or obstacle within the bulb.
II Is, furthermore. an accepted view that
the projected Jumps OF matter act as in
elastic bodies. similarly TO ever so many
small lead bullets. II can be easily shown
that the velocity OF the stream may be as
much as one hundred kilometers secoud,
or even more.
sHATTEREDINToFR
But. now. matter moving with such
great velocity mist surely penetrate great
thicknesses OF the obstruction in its path,
If the laws OF mechanical impact are at all
applicable 10 a catholic stream. I have
presently so much famiiarized myself with
this view that. if had no experimental
evidence. would pot question the fact
that suine matter is projected through the
thin wall Vf vacuum tube. The exit
from the latter is. however, the more likely
to occur. as the Jumps of matter must 10
shattered into stillmuch smaller particles by
the impact.
From my experiments it appears that
the Jumps or molecules are indeed shattered
into fragments or constituents smn!l as
to make them lose entirely some physical
characteristic much smaller particles By
the impact.
The eInattercoIEposing the cathode stream

all evidence, reduced to matter of some
primary form, heretofore not known, as
such veiocities and such violent impacts
have probably never been studied or even
attaiBed before these extra dordinary mani
fes,ations were observed. Is 1T not possible
that the very ether vorteNes which, accord

the Jumps. are dissolved, and that in the
Rnentgen pheronena we may witness a
transformation of ordinary rpatter into
ether. It is in this sense that, I think.
Roentgen's first hypothesis will be con-
firined.
The important fact pointed out early by
Roentgen and confirmed by subsequent re-
searcil-nameiy that a body is the more
opaque to the rays the t!enser il is-eannot
be explained as satisfactorily under any
other assumption as that Of he rays being
streams of matter in which case such SIM
pie relation between opacity and density
would necessarily exist This relation Is the
more important In its bearing rpon the ra-
turc OF the rays. as il does not at all exist
in light-givins vibrations. and should couse-
queptly not be found To SO marked a degree
and under all Conditions with vibrations. pre-
sumably similar TO and approxinatinS in
frequency the light vibrations
AN almost crucial test OF the existence
OF material streams is afforded by the for
nation of shadows in space at distance
from the bulb Such shadows could not he
