STT0 HERE Is on exhibition Al the Paris
exposition recording telephone
| known as the teiegraphone. which
Is based on an entirely new pfin-
eSpie, and which. although Il Is not vi
perfected. promises "a eventually prove
valuable addition 10 the present methods
of long distance communication. The adj
yantagces OF an apparatus that viii salts
factorily record the message Transmitted
through an ordinary telephone are ohsi-
Gus enough. and after the Invention OF ths
photograph II was predicted that this ~
suit would soon be attained. But tie
practical difficulties have proved 50 great
that until very recently there has been no
even fairly successful combination of me
