The velocity OF electric waves through the Atlantic
cables mas been ascertained 10y Professor Gould to
be from 1000 TO 5000 miles per second. Telegraph
wires upon poles IN the air conduct the electric
waves with velocity more than double THIS. IL is
curious fact that the rapiditY Of the transmission
increases with the distance between the wire and
the eartn, or with the height Of the support. The
journal des Ielegsd pies says that wires placed upon
poles slightly elevated transmit signals with
l0city OIL IL 600 miles second; ana those con-
siderable height give velocity OF 16o 900 20 900
miles.
