The amalgamating of a surface of a metallic object before silver
plating. It secures better adhesion of the deposit. It is executed by
dipping the article into a solution of a salt of mercury. A solution of
mercuric nitrate 1 part, in water 100 parts, both by weight, is used.

A mineral, silica, SiO2. It has recently been used by C. V. Boys and
since by others in the making of filaments for torsion suspensions. The
mineral is melted, while attached to an arrow or other projectile. It is
touched to another piece of quartz or some substance to which it adheres
and the arrow is fired off from [...]

An electric meter for determining the quantity of electricity which
passes through it, expressible in coulombs or ampere hours. All
commercial meters are quantity meters.

Quantity is determined electro-statically by the repulsion a charge of
given quantity exercises upon an identical charge at a known distance.
The force evidently varies with the product of the two quantities, and
by the law of radiant forces also inversely with the square of the
distance. The dimensions given by these considerations is Q * Q/(L*L).
This is the [...]

The quantity of electricity passed by a unit current in unit time; the
quantity passed by one ampere in one second; the coulomb.
It is equal to 3E9 electrostatic absolute units of quantity and to 0.1
of the electro- magnetic absolute unit of quantity.
One coulomb is represented by the deposit of
.00111815 gram, or .017253 grain of silver,
.00032959 gram, [...]

Electro-magnetic. Quantity is determined electro-magnetically by the
measurement of current intensity for a second of time: its dimensions
are therefore given by multiplying intensity or current strength by
time. The dimensions of intensity are
( (M^.5) * (L^.5) ) / T
therefore the dimensions of electro-magnetic quantity are
( ( (M^.5) * (L^.5) ) / T ) * T = ( [...]

Electricity may be measured as if it were a compressible gas, by
determining the potential it produces when stored in a defined
recipient. In this way the conception of a species of quantity is
reached. It is also measured as the quantity of current passed by a
conductor.
Thus a body whose surface is more or less highly charged with
electricity, [...]

This term is used to express arrangements of electrical connections for
giving the largest quantity of current, as a quantity armature, meaning
one wound for low resistance.
A battery is connected in quantity when the cells are all in parallel.
It is the arrangement giving the largest current through a very small
external resistance.
The term is now virtually obsolete (Daniell); [...]

Involving the determination of quantities. Thus a simple test would
indicate that a current was passing through a wire. This would be a
qualitative test. If by proper apparatus the exact intensity of the
current was determined, it would be a quantitative determination. (See
Qualitative.)

The distinguishing characteristic of a sound other than its pitch; the
timbre.
It is due to the presence with the main or fundamental sound of other
minor sounds called overtones, the fundamental note prevailing and the
other ones being superimposed upon it. The human voice is very rich in
overtones; the telephone reproduces these, thus giving the personal
peculiarities of every [...]
