The velocity imparted to a body in one second by the action of
gravitation at any standard point upon the earth’s surface in a vacuum.
This will vary at different places, owing principally to the variation
in centrifugal force due to the earth’s rotation. For standard valuation
it must be reduced to sea level. The following are examples of [...]

A natural force which causes all masses of matter to attract each other.
Its cause is unknown; it is often supposed to be due to the luminiferous
ether.
[Transcriber's note: Einstein's explanation of gravity, General
Relativity and the curvature of space-time, came 23 years later, 1915.]

Carbon; one of three allotropic modifications of this element. It occurs
in nature as a mineral.
It is used as a lubricant for machinery; for commutator brushes; for
making surfaces to be plated conductive, and for mixing with manganese
binoxide in Leclanché cells.

The number of grams of a substance equal numerically to its molecular
weight.

The number of grams of an element equal numerically to the atomic
weight, as 16 grams of oxygen, 1 gram of hydrogen, 35.5 grams of
chlorine; all which might be expressed as gram-atoms of oxygen, hydrogen
and chlorine respectively.
The gram-atom approximately expresses the number of gram-calories
required to heat one gram of the substance 1º C. (1.8º F.). This [...]

The unit of weight in the metric system; accepted as the unit of
mass in the absolute of C. G. S. system of units. It is the
one-thousandth part of mass of a standard weight preserved under proper
conditions in Paris, and supposed to be the mass of a cubic decimeter of
distilled water at the temperature of the [...]

Apparatus for enabling the same line to be used for telegraph signals
and telephoning.
One type consists in coils with iron cores or simply electromagnets.
These act to retard the current in reaching its full power and also
prolong it. This gives a graduated effect to the signals, so that the
telephone diaphragm is not audibly affected by the impulses.
The [...]

A bath for removing gold from plated articles without dissolving the
base in order to save the precious metal. A bath of 10 parts of
potassium cyanide and 100 parts of water may be used, the articles to be
stripped being immersed therein as the anode of an active circuit. If
the gilding is on a silver or copper [...]

A solution of gold used for depositing the metal in the electroplating
process.
A great number of formulae have been devised, of which a few
representative ones are given here.
COLD BATHS.            HOT BATHS. Water,               10,000  10,000  10,000  10,000   5,000  3,000 Potassium Cyanide,      200      –     200      10      –     50 Gold,                   100      15     100      10      10     10 Potassium Ferrocyanide,  [...]

A metal, one of the elements; symbol Au. c .; atomic weight, 196.8;
equivalent, 65.6; valency, 3; specific gravity 19.5.
It is a conductor of electricity.
Annealed.   Hard drawn. Relative Resistance (Annealed Silver = 1),   1.369       1.393 Specific Resistance,                         2.058       2.094 Resistance of a wire at 0° C. (32°F.) (a) 1 foot long, weighing 1 grain,          [...]
