To BE told that telegraph wire which is
buslly transmitting long message can at the
same time be made to convey half dozen other
messages in opposite directions sounds
like fairy tale; but that the thing can be done
and ID daily being done, is attested upon the
most respectable scientific authority, says the
st. James Gazette. The discovery which rem
ders these astonishing results possible is due to
