yellow, according as a greater or less pro- 

 proportion of lead has been used. The 

 lead promotes also the vitrification ; the 

 flint serves to give a consistency to the 

 lead during the time of its vitrification, 

 and to prevent its becoming too fluid, 

 and running down the sides of the ware, 

 and thereby leaving them unglazed. 

 This kind of glazing by lead is liable to 

 be attacked by acids, and of acting in 

 some degree as a poison ; a substitute has 

 therefore been recommended, which con- 

 consists of equal parts of white glass and 

 soda finely pulverized, and exposed to a 

 Strong heat till quite dry, and with this 

 the vessels are varnished or glazed. See 

 POTTERY. 



GLEANING, in law. It hath been 

 said, that, by the common law and custom 

 of England, the poor are allowed to enter 

 and glean upon another's ground, after 

 the harvest, without being guilty of tres- 

 pass ; and that this humane provision 

 seems borrowed from the Mosaical law ; 

 but it is now positively settled, by a so- 

 lemn judgment of the court of Common 

 Pleas, that a right to glean in the harvest 

 field cannot be claimed as a general right 

 by every person at common law ; nor as 

 a custom by the poor of a parish, legally 

 settled. 



GLEBE, or Glebe-land, is a portion of 

 Jand, meadow, or pasture, belonging to, 

 or parcel of, the parsonage or vicarage, 

 over and above the tythes. 



Glebe lands, in the hands of the par- 

 son, shall not pay tithes to the vicar; nor, 

 being in the hands of the vicar, shall 

 they pay tithes to the parson. By statute 

 28 Hen. VIII. c. 11, every successor, on 

 a month's warning after induction, shall 

 have the mansion-house, and the glebe 

 belonging thereto, not sown at the time 

 of the predecessor's death. He that is 

 instituted may enter into the glebe-land 

 before induction, and has right to have it 

 against any strangers.

 ground-ivy, a genus of the Didynamia 

 Gymnosperrnia class and order. Natural 

 order of Verticillatse. Labiatae, Jussieu.

 G. hederacea, ground-ivy. 



GLEDITSIA, in botany, a genus of the 

 Polygamia Dioecia class and order. Na- 

 tural order of Lomentacex. Leguminosae,

 phrodite ; calyx four-cleft ; corolla four- 

 petal led ; stamens six ; pistil one, le- 



gume. There is only one species, with 

 several varieties. 



GLEE, in music, a vocal composition 

 in three or more parts, generally con 

 sisting of more than one movement, the 

 subject of which may be either gay, 

 tender, or grave ; bacchanalian, amatory, 

 or pathetic. 



GLEET, in medicine, the flux of a thin, 

 limpid humour from the urethra. 



GLINUS, in botany, a genus of the 

 Dodecandria Pentagynia class and order. 

 Natural order of Coryophyllei. Ficoi- 

 deae, Jussieu. Essential character : calyx 

 five-leaved; corolla none ; nectaries clo- 

 ven bristles ; capsule five-cornered, five- 

 celled, five-valved, containing numerous 

 seeds. There are three species. 



GLOBBA, in botany, a genus of the 

 Diandria Monogynia class and order. 

 Natural order of Scitamineae. pannae, 

 Jussieu. Essential character: calyx su- 

 perior, trifid ; corolla equal, trifid ; cap- 

 sule three-celled ; seeds very many. 

 There are four species. 



GLOBE, a round or spherical body, 

 more usually called a sphere, bounded by 

 one uniform convex surface, every point 

 of which is equally distant from a point 

 within, called its centre. Euclid defines 

 the globe or sphere, to be a solid figure 

 described by the revolution of a semi-cir- 

 cle about its diameter, which remains 

 unmoved. Also, its axis is the fixed line 

 or diameter about which the semi-circle 

 revolves ; ami its centre is the same with 

 that of the revolving semi-circle, a diame- 

 ter of it being any right line that passes 

 through the centre, and terminated both 

 ways by the superficies of the sphere. 



Euclid, at the end of the twelfth book, 

 shews that spheres are to one another in 

 the triplicate ratio of their <* meters, 

 that is, their solidities are to or^ttanother 

 as the cubes of their diameters. And 

 Archimedes determines the real magni- 

 tudes and measures of the surfaces and 

 solidities of spheres and their segments, 

 in his treatise " De Sphaeraet Cylmdro:" 

 viz. 1. That the superficies of any globe 

 is equal to four times a great circle of it. 

 2. That any sphere is equal to two-thirds 

 of its circumscribing cylinder, or of the 

 cylinder of the same diameter and alti- 

 tude. 3. That the curve surface of the 

 segment of a globe, is equal to the 

 circle whose radius is the line drawn from 

 the vertex of the segment to the circum- 

 ference of the base. 4. That the content 

 of a solid sector of the globe is equal 

 to a cone whose altitude is the radius of
