An improved multiple Geographic
instrument has been introduced into
France, in which each key sends over
the line wire at each operation an in
termlttent current corresponding to
dennlte number of vibrations minute.
The receiving saunders are each in
similar way sensitive only to currents
having determined rate of vibrations
to one of the transmit
ting keys. Consequently each receiver
selects and responds to the current
sent by transmitter having a CORE
spending period of vibrations.
