Some sample entries:
CHEMILUMINESCENCE
The emission of light during a chemical reaction. e.g. the oxidation of yellow phosphorus. The light emitted by the fire-fly or glow-worm, and luminous combustion, are examples of this very common phenomenon. Used analytically and in `light studies' where a reaction gives an active intermediate which transfers energy to a dyestuff which fluoresces under the influence of the absorbed energy.
GOLD, STANDARD
Pure gold is too soft for use as ornaments or for coinage, and is alloyed with copper or silver, or both. The fineness is expressed either in parts per thousand, or in carats. Pure gold is 24 carat fine, and the five standard alloys of 22, 18, 15, 12 and 9 carats, i.e. parts of gold in 24 of alloy, are legalized.
NATURAL GAS
Gas obtained from underground accumulations which may or may not be directly associated with crude oil. Such gas would normally contain at least 90% methane and other low-boiling hydrocarbons, the remainder being nitrogen and carbon dioxide. When natural gas is associated with crude oil it frequently contains appreciable amounts of higher hydrocarbons, pentanes, hexanes, etc., and is referred to as wet gas. Used as a fuel and raw material.
