When electrical dis

insulating-film, which gives way and allows o
the passage current which can util
ized operate any form circuit-controlling
apparatus.
In the followingdetailed description shall
65 confine myself explanation that
method and apparatus only which have
found the most practical and effectual;
but obviously invention its broad fea
tures not limited the special mode add
appliances which have devised and shall 70
here describe.
Still another way pass the currents
simply through the ground connecting

A great variety electrical and other de
vices more less suitable for the purpose of
detecting and utilizing feeble actions are now
well known scientific men and artisans and
need not all enumerated here.

In any event—that say, whichever of
the above similar plans may adopt—and
particularly when the influence exerted from

evidently owing electrostatic attraction,

thus establishing good electrical connection
between the two terminals.
Still another modified device, which may 130
be said embody the features both the

myself merely the electrical the most

to those which, while not the most sensitive,
are perhaps more readily available from the

ing them, may state that contrivance may
be Used which has long been known and used
as lightning-arrester connection with
telephone-switchboards for operating annun

state may made use number ways
for the above purpose.
Another way carry out invention is
to direct the currents discharges high-

directly, inductively with the ground and
the other body, preferably large sur

to secure the best action the receiving-circuit

Again, another contrivance capable be

my invention, electrical oscillations which
do not follow any particular condupting-path,
but propagate straight lines through space,
