| Edridge-Green lamp | A lantern used to test recognition of coloured signals; it displays a single light with colour filters in rotating disks that can be modified to simulate conditions of weather and atmosphere. This test for colour blindness was officially adopted in Great Britain in 1915 in place of the Holmgren wool test, but is now seldom used. (05 Mar 2000) |

| lamp | 1. A light-producing vessel, instrument or apparatus; especially, a vessel with a wick used for the combustion of oil or other inflammable liquid, for the purpose of producing artificial light. 2. Figuratively, anything which enlightens intellectually or morally; anything regarded metaphorically a performing the uses of a lamp. "Thy word is a lamp unto my feet, and a light unto my path." (Ps. Cxix. 105) "Ages elapsed ere Homer's lamp appeared." (Cowper) 3. <physics> A device or mechanism for producing light by electricity. See Incandescent lamp, under Incandescent. Aeolipile lamp, a hollow ball of copper containing alcohol which is converted into vapor by a lamp beneath, so as to make a powerful blowpipe flame when the vapor is ignited. Arc lamp, any brachiopod shell of the genus Terebratula and allied genera. The name refers to the shape, which is like that of an antique lamp. See Terebratula. Safety lamp, a miner's lamp in which the flame is surrounded by fine wire gauze, preventing the kindling of dangerous explosive gases; called also, from Sir Humphry Davy the inventor, Davy lamp. To smell of the lamp, to bear marks of great study and labour, as a literary composition. Origin: F. Lampe, L. Lampas, -adis, fr. Gr, torch, fr. To give light, to shine. Cf. Lampad, Lantern.

| mercury | 1. <astronomy> The first planet in order from the sun. It has no known natural satellites. It is one of the four inner or terrestrial planets of the solar system. It is the planet nearest the sun, from which its mean distance is about 36,000,000 miles. Its period is 88 days, and its diameter 3,000 miles. 2. <chemistry> A metallic element mostly obtained by reduction from cinnabar, one of its ores. It is a heavy, opaque, glistening liquid (commonly called quicksilver), and is used in barometers, thermometers, ect. Specific gravity 13.6. Symbol Hg (Hydrargyrum). Atomic weight 199.8. Mercury has a molecule which consists of only one atom. It was named by the alchemists after the god Mercury, and designated by his symbol, <mercury/. Mercury forms alloys, called amalgams, with many metals, and is thus used in applying tin foil to the backs of mirrors, and in extracting gold and silver from their ores. It is poisonous, and is used in medicine in the free state as in blue pill, and in its compounds as calomel, corrosive sublimate, etc. It is the only metal which is liquid at ordinary temperatures, and it solidifies at about -39 deg Centigrade to a soft, malleable, ductile metal. 3. Sprightly or mercurial quality; spirit; mutability; fickleness. "He was so full of mercury that he could not fix long in any friendship, or to any design." (Bp. Burnet) 6. <botany> A plant (Mercurialis annua), of the Spurge family, the leaves of which are sometimes used for spinach, in Europe. The name is also applied, in the United States, to certain climbing plants, some of which are poisonous to the skin, especially. To the Rhus Toxicodendron, or poison ivy. Origin: L. Mercurius; akin to merx wares. Source: Websters Dictionary (25 Jun 1999) |
| mercury bichloride | <chemical> Mercury chloride (hgcl2). A highly toxic compound that volatises slightly at ordinary temperature and appreciably at 100 degrees c. It is corrosive to mucous membranes and used as a topical antiseptic and disinfectant. Pharmacological action: anti-infective agents, local, disinfectants. Chemical name: Mercury chloride (HgCl2) (12 Dec 1998) |

| mercury isotopes | Stable mercury atoms that have the same atomic number as the element mercury, but differ in atomic weight. Hg-196, 198-201, and 204 are stable mercury isotopes. (12 Dec 1998) |
| mercury poisoning | A disease usually caused by the ingestion of mercury or mercury compounds, which are toxic in relation to their ability to produce mercuric ions; usually acute mercury poisoning is associated with ulcerations of the stomach and intestine and toxic changes in the renal tubules; anuria and anaemia may occur; usually chronic mercury poisoning is a result of industrial poisoning and causes gastrointestinal or central nervous system manifestations including stomatitis, diarrhoea, ataxia, tremor, hyperreflexia, sensorineural impairment, and emotional instability (Mad Hatter syndrome). Synonym: hydrargyria, hydrargyrism, mercurialism. (05 Mar 2000) |
| mercury protoiodide | HgI;used externally as an ointment in eye diseases. Synonym: mercury protoiodide, yellow mercury iodide. (05 Mar 2000) |
| mercury radioisotopes | Unstable isotopes of mercury that decay or disintegrate emitting radiation. Hg atoms with atomic weights 185-195, 197, 203, 205, and 206 are radioactive mercury isotopes. (12 Dec 1998) |
