| by-law | 1. A local or subordinate law; a private law or regulation made by a corporation for its own government. "There was likewise a law to restrain the by-laws, or ordinances of corporations." (Bacon) "The law or institution; to which are added two by-laws, as a comment upon the general law." (Addison) 2. A law that is less important than a general law or constitutional provision, and subsidiary to it; a rule relating to a matter of detail; as, civic societies often adopt a constitution and by-laws for the government of their members. In this sense the word has probably been influenced by by, meaning secondary or aside. Origin: Cf.Sw.bylag, D.bylov, Icel.barlog, fr.Sw.& Dan. By town, Icel. Baer, byr (fr. Bua to dwell) + the word for law; hence, a law for one town, a special law. Cf.Birlaw and see Law. Source: Websters Dictionary (01 Mar 1998) |

| Galton's law | In a population mating at random, the progeny of a parent with an extreme value for a measurable phenotype will tend on average to have values nearer the population mean than in the extreme parent. See: law of regression to mean. Synonym: law of regression to mean. (05 Mar 2000) |
| Magendie's law | The ventral spinal roots are motor, the dorsal are sensory. Synonym: Bell-Magendie law, Magendie's law. (05 Mar 2000) |
| van der Kolk's law | In a mixed nerve, the sensory fibres are distributed to the parts moved by the muscles controlled by the motor fibres. (05 Mar 2000) |
| van't Hoff's law | In stereochemistry, all optically active substances have one or more multivalent atoms united to four different atoms or radicals so as to form in space an unsymmetrical arrangement, the osmotic pressure exerted by any substance in very dilute solution is the same that it would exert if present as gas in the same volume as that of the solution; or, at constant temperature, the osmotic pressure of dilute solutions is proportional to the concentration (number of molecules) of the dissolved substance; i.e., the osmotic pressure, π, in dilute solutions is π = RTσci, where R is the universal gas constant, T is the absolute temperature, and ci is the molar concentration of solute i, the rate of chemical reactions increases between two-and three-fold for each 10캜 rise in temperature.

| Gay-Lussac's law | All gases expand equally on heating, namely, 1/273.16 of their volume at 0캜 for every degree Celsius. Synonym: Gay-Lussac's law. (05 Mar 2000) |
| Raoult's law | The vapor pressure of a solution of a nonvolatile nonelectrolyte is that of the pure solvent multiplied by the mole-fraction of the solvent in the solution. (05 Mar 2000) |
| Marey's law | The pulse rate varies inversely with the blood pressure; i.e., the pulse is slow when the pressure is high; an expression of baroreceptor reflex influences on heart rate. (05 Mar 2000) |

| reciprocity law | In two photochemical reactions, e.g., the darkening of a photographic plate or film, if the product of the intensity of illumination and the time of exposure are equal, the quantities of chemical material undergoing change will be equal; the retina for short periods of exposure obeys this law. Synonym: reciprocity law, Roscoe-Bunsen law. (05 Mar 2000) |
