I If a fellow was to tell you he
could hear your face, would you
get sore, or would you politely
ask him how loudly the sun was
Of course, any one who could
hear yoTur face or your clothes
could hear the sunshine and the
moonbeams and the dainty white
skirt tripping sweetly up the
street, for he would have an opto
phone. The device that makes light
audible, invented by Fournier
d'Albe and exhibited by him to
the members of the Royal Society
in London.
The apparatus enables the to
tally blind to hear the 'light they
cannot see. It enables them to
locate windows or open, doors in a
house and to locate persons
whose clothing is either much
darker or much lighter than their
The optophone is a small box,
something like a camera, which
the blind man carries n front of
him. A head band holds the tele
phone to the ear. Through a
small hole light is thrown upon
the selenium cell which produces "
an electric current interrupted by
a special clockwork interrupter,
and so made audible in the tele
phone. On a bright moonlight night '
the moon sounds quite loudly, but
for real noise try to hear the sun
shine! One bright sunbeam can r
make more noise in an optophone '
than a Niagara Falls. An elec
tric light on a black background J
sounds like a boiler factory.
The inventor believes that with i
the optophone a blind person may
get around much better than he i
now can, for the optophone will t
tell him where an object begins j
and where it leaves off. With that '
apparatus a blind person, says
the inventor, can hear the light of j
stars invisible through the tele- f
scope. 3
