A prefix; one million times. Thus myriavolt means one million volts.
[Transcriber's note: Contemporary usage is mega, as in megavolt.]

A species of voltaic battery, often termed Matteueci’s pile, made up of
alternate pieces of muscle cut longitudinally and transversely
respectively. The different pieces represent the elements of a battery,
and their difference of potential is naturally possessed by the pieces.

When a resistance is placed in parallel with a galvanometer on a circuit
the following relation obtains. Let s and g equal the resistances of the
shunt and galvanometer respectively, S and G the currents in amperes
passing through them, V the potential difference between their common
terminals, and A the whole current in amperes. Then we have
A = [...]

Any system of telegraphy transmitting more than four messages
simultaneously over a single wire. Properly it should apply to all
transmitting more than one, but conventionally has the above restricted
meaning, distinguishing it from duplex and quadruplex telegraphy.

A method for suppressing sparking in working electro-magnets
intermittently. The magnet core is wound with a number (from four to
twenty) of separate layers of fine wire. A separate wire is taken for
each layer and all are wound in the same direction, from one end to the
other of the space or bobbin without returning. The ends are [...]

A switch board on whose face connecting spring jacks or other devices
are repeated for the same circuits, so that different operators have
each the entire set of connections repeated on the section of the board
immediately in front of and within their reach. This multiplication of
the same set of connections, giving one complete set to each operator,
gives [...]

Arrangements of electric apparatus in a circuit in a number of series,
which minor series are then arranged in parallel. The term may be used
as a noun, as “arranged in multiple-series,” or as an adjective, as “a
multiple-series circuit.”

A resistance box arranged so that the coils may be plugged in multiple
instead of in series. Such can be used as a rheostat, as the resistance
can be very gradually changed by putting the coils one by one into
parallel with each other. Thus by adding in parallel with a 10 ohm coil
a 10,000 ohm coil the [...]

A term expressing connection of electric apparatus such as battery
couples, or lamps in parallel with each other. In the ordinary
incandescent lamp circuits the lamps are connected in multiple.
Synonym–Multiple Arc.

A motor whose winding on the armature is in parallel with the winding on
the field magnets. It is similar to a shunt wound dynamo. (See Dynamo,
Shunt.)
