TELEeRAPHlc DISCOVERIES.
Progress and History OF the Inven-
Ifon.

tfon.
Six hundred years B. c.. Thales of
Milete noted the electrical phenomena
developed by friction upon amber; two
hundred years later Plato theorized up
on electricity. and A. ID. 1922 Martini
go, Venetian. the engineer in defense
OF Rhodes. applied one end of drum
head at the end of his counter mine to
discover the vicinity and direction of
the eDemy's underground galleries,
and thus, by utilizing the molecular
disturbance of the earth in sound
waves, conceived the basis of tele-
ph0ny. 1t was not. however, until A.
ID. 1890. that Won Guerick made the
first machine for generating FRACTIONAL
electricity, nor until A. ID. 1926. that
Wood recorded the fact that frictional
electricity would pass through con-
siderable length of wire, and could
therefore be utilized for the transmits
sion of signals. TO Wood of England
is therefore due the honor of first sug-
costing the feasibility of electric teIe-
graphy.
A. ID. 1875. Murschenbrok. Germany,
invented the Leyden jar. by which
means FRACTIONAL electricity could be
stored for experimental purposes. A.
ID. 1747, DR. Watson. England. erected
the first telegraph line between Shoot
ars Hill and London; and A. ID. 1853,

Charles Mathews) published the man
ner in which he had indicated the let
ters of the alphabet through system
of twenty-six wires, by frictional cleo
tricity. During the latter half of the
eighteenth century inventors of all ma
lions endeaVored, by means of two or
more wires and friction al electricity,
TO transmit intelligence between dis
amt places; but it was not until A. d.
1900, when Volta proclaimed his own
and Galyani's prior experiments in the
production of chemical electricity. that

became practicable.
A. ID. 1919 0ersted Denmark) dis
covered that a freely suspended mag
nelized needle would move to the right

Of current of electricity through an
adjacent wire.
A. ID. 1920. Arago (France) discov-
cred that when bar of soft iron was
wound with copper or insulated iron
ron wire. it became a magnet when
ever current of electricity trayersed
he wire, and was Immediately demag-
letized Tor nearly SOY when the wires

current
A. ID. 1882. Faraday England) dis
covered that when a coil of insulated
wire was placed adjacent to. but not
connected with. another coil of wire.
through which an intermittent current
Of electricity was passed. induced cur
rents of increased intensity and alter
Mating polarity were developed in the
unattached coil. Also that the move
ment of permanent bar magnet with
n coil of wire, or the movement of
an electromagnetic near the poles of a
permanent magnet would develop
currents of electricity.

,ries of Galvani and Volta, oersted,
