LIN 



crinnoidea. Its position is the muschel- 

 kalk of the new red sand-stone group. 



LIMACI'NA, a genus of mollusca sc-pa- 

 ratod from the Clio, Lin., by Cuvier. The 

 animal uses its shell as a boat, and its 

 wings as oars whenever it wishes to na- 

 vigate the surface of the deep arctic seas. 



LIMAX, the slug. A genus of terrestrial 

 pulmonea, having no apparent shell. 

 This genus in the system of Linna?us com- 

 prises the Limax, Arion, Lima, Vaginu- 

 lus, Testacella, and Parmacella of Cuvier. 

 Name Umax, a snail, so called from its 

 slimlness. 



LIMB, Lat. limbus. An edge or border, 



as the sun's limb. 2. The graduated 



edge of a quadrant, astrolabe, &c. 3. 



The upper spreading part of a monopeta- 



lous corolla. 4. An extremity of the 



body, as an arm or leg. 



LIM'BAT, a cooling periodical wind in 

 the island of Cyprus, which blows from 

 the north-west from 8 o'clock a.m. till 

 noon. 



LIM'BERS. Limber holes are square holes 

 cut through the lower part of a ship's 

 floor timbers, very near the keel, form- 

 ing a channel for water, and communi- 

 cating with the pump-well through the 

 whole length of the floor. Limber boards, 

 short pieces of plank which form a part 

 of the lining of a ship's floor close to the 

 keelson and immediately above the tim- 

 bers, for the convenience of keeping a 

 clear passtge to the well. Liv&r rope, a 

 long rope frequently retained in the lim 

 ber holes of a ship, in order to clear them 

 by pulling the rope backwards and for- 

 wards. Limber carriage, a sort of ad- 

 vanced train joined to the carriage of a 

 cannon while on march, having boxes for 

 ammunition. 



Lm'Bo.Lat. limbus, a hem or edge. The 

 purgatory of the Humanists, supposed to 

 lie on the edge or neighbourhood of hell. 



LIMBUS, that portion of petals of flowers 

 which is supported by the unguis. 



LIME. 1. In mineralogy, the oxide of 

 calcium, one of the primitive earths, 

 much used in building and for other pur- 

 poses, being the most essential ingre- 

 dient in all cements. It is never found 

 native or in a state of purity, but is al- 

 ways combined with acids, particularly 

 in the state of carbonate, as marble, lime- 

 stone, and chalk, from which it may be 

 obtained nearly pure by simple calcina- 

 tion. "When any carbonate of lime is 

 properly calcined, the result is quick lime 

 and this slacked with water forms hydrate 

 of lime or slack lime. Lime is also found 

 combined with sulphuric acid, forming 

 ffypsum and anhydrite, and with the fluo- 

 rine forming Derbyshire spar. It likewise 

 combines with phosphoric acid, and forms 



bones and shells. 2. In botany, a fruit 



like a small lemon, that of the Citrus U- 



metta, which grows abundantly in the 

 "West India Islands, and in other warm 

 climates. 



LIME'STONE. Calcareous stone. A genus 

 of mineral, comprehending, according to 

 Jameson, four species :,'!). Rhomb-spar ; 

 (2). Dolomite ; (3). Arragonite ; (4). Lime- 

 stone. The same mineralogist divides 

 this last into 12 sub-species: (1). Fo 

 Hated limestone, comprehending calcare- 

 ous spar and marbles ; '21. Compact lime- 

 stone, comprehending the common com- 

 pact limestone (usually burned to produce 

 lirne), blue Vesuvian limestone and roe- 

 stone; (3). Chalk; (4). Agaric mineral or 

 rockmilk ; (5). Fibrous limestone, com- 

 prehending satin-spar and calc-spar; 

 (6). Cale-tuff; (7). Pea-stone; (8). Slate- 

 spar , (9). Aphrite ; (10). Lucullite, com- 

 prehending the Kcro antico of the Italians, 

 slinkstone or swinstone, and madreporite ; 

 (11). Marl; (12). Bituminous marl-slate. 



LIME-TREE, the Tilia europtca, called 

 also the linden-tree. See Ti LI A. The lime- 

 tree of the West Indies is the Citrus ame- 

 ricana. 



LIME'-WATER, an aqueous solution of 

 lime. Lime is very slightly soluble in 

 water, and less so in hot than in cold 

 water. 



LIM'IT, from hmes, border. In mathe- 

 matics, a determinate quantity, to which 

 a variable one continually approaches. 

 Thus a circle is the limit of all its in- 

 scribed and circumscribed polygons. 



LIMKJE'US, a genus of Molluscs, inhabit- 

 ing stagnant water in great numbers; 

 placed by Cuvier, order Pulmonea, and 

 class Gastropoda ; and by Lamarck in the 

 family Limnacea. The shell is a turreted 

 univalve, with an oblong spire, and of a 

 light amber colour. It abounds as a fossil 

 in calcareous strata. 



LIMO'SA, the god wit. A genus of birds. 

 Order Grallatoriai, family Longiro&tres. 

 Their form is more slender, and their legs 

 are longer, than those of the snipes ; they 

 frequent salt-marshes and the sea-snore. 



LIMO'SIS, a genus of diseases character- 

 ised by depraved, excessive, or defective 

 appetite. 



LIM'ULUS, the Molucca crab. A genus 

 of Crustaceans. Order Peecilopoda, family 

 Xyphosnra. The limuli are sometimes 

 found two feet in length ; they inhabit the 

 seas of hot climates, and most frequently 

 their shores. The L. cyclops is found in 

 France, and is commonly called casse- 

 role, from its shape. It is the king-crab or 

 horse-shoe of our fishermen. 



LI.NA'KIA. 1. In botany, the toad-flax, 

 from linwn, flax, so named from the re- 

 semblance of its leaves to fhose of flax. 



2. In ornithology, a sub-genus of the 



sparrow-tribe of birds, comprehending the 

 linnets and canary-bird.
