certain degree of intensity The strain I
upon the sir becomes TOO great. and 1
spark passes between the Two con
densers. b y Ehich equilibrium is re-
stored between them.
The passage Of this spark produces,
% 10 speak. 3 shock IN the ether,
which. ike the explosion Of 8 gun or 4
the urrerz nee u 8 sound, sets up a Sc
RES OF waves In the surrounding ne
diun. which radizte away On all sides
These waves IN the ether produce the
electric -v0icsr II the sparks are reg
alated Ia number snd frequency the
consequent waves are similarly regu- 4
lated. Al Instrument for the produc-
don Of such waves is called an oscilia-i ]
TOR or EXETER Ii Is kind Of vocal sP=
paratHs for speaking through the ether
instead Of through the air.

We were not provided with ears TO hear

ana dssh instrument. IS In ordinary
telegTaphy by wire
But the electric voice and the else.
rrie ear are ia some ways more man
agssble than the human voice and ear. /
We can only produce and hear air 4
waves Of g limited range Of frequency, !
and ne cannot do much TO alter that
limit.
Sound waves vibrating less than
forty times q seeond or more than 90 /
OOO times are fnaudible to Us. But elee-
rrie waves varying IN frequency from 4
= few hundred up 70 hundreds Of nil
hons a second can be rendered per !
eepuble. and it IS also possible 50 70 4
construct the instruments that thsy I
will send form and receive particular /
ranges of waves and Be mute and 1
deaf 70 others
Then the distance ever which the 4
electric waves can be detected Is al /
mozt infinitely greater than that of j
ordinary sound waves. Il Jaks a
strong voiced man 70 make MS voice 1
audible across Z little riFeT. but, IS
everybody knows. the electric CRY Of 9 4
ship IL distress can be electrically i
heard from the middle Of the Atlantic
ocean. And there are enthusiasts who 1
predict that before very hong We shall /
Be able 70 speak By wireless TO some
other planet. II only there IS somebody 4
there 70 hear and understand us.-
