liable to be attacked by acids, and of act- 
ing in some degree as a poison ; a substi- 
tute has therefore been recommended, 
which 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

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 har- 
vest, without being guilty of trespass ; and 
that this humane provision seems borrowed 
from the Mosaical law ; but it is now posi- 
tively settled, by a solemn judgment of the 
court of Common Pleas, that a right to 
glean in the harvest field cannot be claim- 
ed 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 
land, meadow or pasture, belonging to, or 
parcel of the parsonage or vicarage, over 
and above the tithes. 
Glebe lands, in the hands of the parson, 
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- 
ry 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 prede- 
cessor’s death. He that is instituted, may 
enter into the glebe-land before induction, 
and has right to have it against any 
strangers.

more than one movement, the subject of 
which may be either gay, tender, or grave ; 
bachanalian, amatory, or pathetic.

limpid humour from the urethra.- 
GLO 
GLINUS, in botany, a genus of the Do* 
decandria Pentagynia class and order. Na- 
tural order of Coryophyllei. Ficoideae, Jus- 
sieu. Essential character: calyx five-leaved ; 
corolla none ; nectaries cloven-bristles ; cap- 
side five-cornered, five-celled, five-valved, 
containing numerous seeds. There are 
three 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-circle about its 
diameter, which remains unmoved. Also, 
its axis is the fixed line or diameter about 
which the semi-circle revolves ; and its cen- 
tre is the same with that of the revolving 
semi-circle, a diameter 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 diameters, that 
is, their solidities are to one another as the 
cubes of their diameters. And Archimedes 
determines the real magnitudes and mea- 
sures of the surfaces and solidities of spheres 
and their segments, in his treatise “ De 
Sphsera et Cylindro :” viz. l.That the su- 
perfices 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 cy- 
linder, or of the cylinder of the same diame- 
ter and altitude. 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 the 
globe, and its base equal to the curve super- 
ficies or the base of the sector, with many 
other properties. And from hence are ea- 
sily deduced these practical rules for the 
surfaces and solidities of globes and their 
segments ; viz. 1. “ For the Surface of a 
Globe,” multiply the square of the diame- 
ter by 3.1416; or multiply the diameter 
by th# circumference. 2. “ For the Soli-
