1t 10 founded upon the we'll known
truth that when selenium ~ struck
by light It's electoral resistance
changes In relation to the amount OF
light which shines upon Il.
The Instruments employed In the
sending and receipt OF the electrical
influence are OF wonderfully simple
workmanship.
The transmitting consists OF
selenium coated cell. upon which any
image may be focussed by camera
lcrs through a transverse slot in
travelling steel belt. The belt
moves perpendicularly across the
face OF the cell, which is made up OF
alternate copper and mica plates, in
sulated from each other, but con-
nected along the edges at one side
by selenium coating. The inten-
sity OF the light reflected upon the
cell will vary as the slot, travelling
across the cell, exposes the coating
to the lights and shades OF the i'm
age.
The maip cell is controlled by what
Is called light control selenium cell,
moving In proportion so much faster
than the main cell that every point
on the surface of the main cell Is
covered. The controlling cell thus
trans ,orms every point OF light into
an electrical impulse and sends It
by wire to q distant receiving sta
tion.
At the receiving Itation is . belt.
with perpendicular slots, rotating so

appear as one slot meets another. The
light comes from a vacuum tube with
IL the bolt, and II varies In accord
wiz the intensity o: the electrical
current from the sending station.

The light which appears at the
slots varied at each point to the
