STONE (0. Eng. shin; the word is See also:common to See also:Teutonic See also:languages, cf. Ger. See also:Stein, Du. See also:steen, See also:Dan. and Swed. sten; the See also:root is also seen in Gr. See also:aria, pebble)  , a detached piece or fragment of See also:rock . The word is thus applied to the small fragments scattered in the ground or on roads, to the See also:water-worn pebbles of the See also:sea See also:shore or See also:river beds, and to the hewn, dressed or shaped rock used as a See also:building material, with which this See also:article deals . A qualifying word generally accompanies " See also:stone " when the See also:term is applied to pieces of rock cut to a particular See also:size and shape and used for a specific purpose, e.g . " See also:mill-stone," " See also:hearth-stone," " See also:grave-stone," &c . The term " See also:precious stone " is used of those minerals which, from their beauty of See also:colour, &c., their rarity, and some-times their hardness, are valued for their suitability for ornaments (see GEMs) . The word is also often applied to many See also:objects resembling a stone or pebble, such as the hard See also:kernel of certain fruits, as of the See also:cherry, See also:plum, See also:peach, &c., or the calculi or See also:con- Also called See also:Janssen (See also:Diet . Nat . Biog.), See also:Jansen and Janson . Possibly he was the See also:brother of the See also:Gerard (Geraert) Jansen or See also:John-son, of See also:Southwark, who in 1616 executed the bust of See also:Shakespeare in See also:Stratford See also:church; but it is uncertain whether the latter was identical with, or the son of, the Dutch See also:tomb-maker Gerard Jansen described in See also:Sir W . See also:Dugdale's See also:Diary as having, in 1593, lived for twenty-six years in See also:England and as the See also:father of five sons.cretions sometimes formed in the See also:gall or urinary See also:bladder or the kidneys (see BLADDER DISEASES and See also:KIDNEY DISEASES) . The " stone " has been a See also:common measure of See also:weight in See also:north-western See also:Europe . In See also:Germany the " See also:Stein" was of 20 to 22 lb .

In the See also:

British See also:system of weights the "legal" stone, or "See also:horse-See also:man's " weight is of 14 lb See also:avoirdupois; in weighing See also:wool it was also of 14 lb, but is now usually 16 lb . The " customary " stone for See also:fish or See also:butcher's See also:meat is of 8 lb . Building-stone.—In selecting a stone for building purposes many important points have to be considered . The stone must be strong enough to See also:bear the load placed, upon it, it must be durable and See also:weather well in the See also:atmosphere of the See also:district, and its colour and See also:appearance need to be studied . It must further be ascertained whether a sufficient See also:supply is available, and the See also:price also must be taken into See also:account; some difficulty is often experienced in obtaining a suitable stone at a moderate cost, and considerations of expense frequently have more to do with the choice of a stone than the architect would wish . Where there is See also:risk of See also:fire, as is often the See also:case in business and factory premises, it is necessary to select a stone able to stand the effect of a See also:great See also:heat without damage . Great experience of the strength of stones and, of their behaviour in different situations is desirable; but even when this knowledge is given and the greatest care is combined with it, some point may be overlooked . For example, the stone facing of the Houses of See also:Parliament at See also:Westminster was chosen on the recommendation of a See also:committee composed of men of eminent scientific and technical skill; yet it has not weathered well because it is not constituted to resist the destroying effects of the See also:London atmosphere . The See also:prime See also:factor in the choice of a building stone should be the See also:climate to which the material has to be exposed . Stone that in the pure See also:country See also:air has proved extremely durable Constttumay quickly decay in an impure See also:city atmosphere, or when subjected to the strong See also:salt winds from the sea. tlOD• Extremes of temperature, too, are, generally speaking, prejudicial to the See also:life of stone, the alternations of heat and See also:cold setting up movements in the substances of the stone, which, though slight, will in many cases hasten its disintegration . There are few materials which more quickly decay and fail than stone placed under unsuitable conditions . An See also:analysis, made by E .
