vour. Ale thus prepared is often drunk as 
an antiscorbutic. The expressed juice,. mix- 
ed with a little wine, and applied morning 
■and evening, is said to destroy specks upon 
horses’ eyes. The plants that grow near it 
do not flourish. It is said to be hurtful to 
horses if they eat much of it. Sheep eat it ; 
horses are not fond of it; cows, goats, and 
swine, refuse it. 
GLED1TSIA, triple-thorned acacia, or 
honey-locust, a genus of the dioecia order, in 
the polygamia class of plants, and in the na- 
tural method ranking under the 33d order, 
lomentaceax The hermaphrodite calyx is 
quadrifid, the corolla tetrapetalous, the sta- 
mina six, one pistil and legumen. The male 
calyx is triphyllous; the corolla tripetalous, 
with six stamina. The female calyx is pen- 
taphyllous ; the corolla pentapetalous, one 
pistil and legumen. 
There is one species. The triacanthos, a 
native of Virginia and Pennsylvania, is of an 
upright growth, and its trunk is guarded by 
thorns of three or four inches in length in a 
remarkable manner. These thorns have also 
others coming out of their sides at nearly 
right angles: their colour is red. The 
branches are smooth, and of a white colour. 
These are likewise armed with red thorns, 
that are proportionably smaller : they are of 
several directions, and at the ends of the 
branches often stand single. The young- 
shoots of the preceding summer are perfectly 
smooth, of a reddish green, and retain their 
leaves often until the middle of November. 
Although there is a peculiar oddity in the. 
nature and position of the spines, yet the 
leaves constitute the greatest beauty of these 
trees: they are doubly pinnated, and of a 
delightful shining green. The pinnated leaves 
that form the duplication do not always stand 
opposite by pairs on the middle rib; the pin- 
na: of which they are composed are small and 
numerous; no less than 10 or 11 pair belong 
to each of them ; and as no less than four or 
five pair of small leaves are arranged along 
the middle rib, the whole compound leaf 
consists often of more than 200 pinna: of this 
fine green colour. They sit close, and spread 
open in fine weather ; though during bad 
weather they will droop, and their upper 
surfaces nearly join, as if in a sleeping state. 
The flowers are produced from the sides of 
the young branches in July: they are a 
greenish catkin, and make little show; 
though many are succeeded by pods that 
have a wonderful effect ; for these are ex- 
ceedingly large, more than a foot, sometimes 
a foot and a half in length, and two inches 
in breadth, and of a nut-brown colour when 
ripe, so that the effect, when hanging on the 
sides of the branches, may easily be imagined. 
We receive the seeds from America in the 
spring, which keep well in the pods, and are 
for the most part good. They generally ar- 
rive in February ; and, as soon as possible 
after, they should be sown in a well-sheltered 
warm border of light sandy earth. If no bor- 
der is to be found that is naturally so, it may 
be improved by applying drift sand, and 
making it fine.. The seeds should be sown 
about half an inch deep, and they will for 
the most part come up the first spring. It 
the summer should prove dry, they must be 
constantly watered; and if shade could be 
afforded them in the heat of the day, they 
would make stronger plants by the autuipn.

A careful attention to this article is peculiarly 
requisite; for, as the ends of the branches 
are often killed, if the young plant has not 
made some progress, it will be liable to be 
wholly destroyed by the winter’s frost, with- 
out protection : and' this renders the sowing 
the seeds in a warm border under a hedge 
in a well-sheltered place necessary ; for there 
these shrubs will endure our winters, even 
when seedlings, and so will require no far- 
ther trouble ; nay, though the tops should be 
nipped, they will shoot out again lower, and 
will soon overcome it. It will be proper to 
let them remain two years in the seed-bed 
before they are planted out in the nursery. 
The spring is the best time for the work. 
These trees are late in the spring before they 
exhibit their leaves, but keep shooting long 
in the autumn. 
G LIN US, a genus of the pentagynia order, 
in the decandria class of plants, and in the 
natural method ranking under the 22 d class, 
caryophylkei. The calyx is pentaphyllous ; 
there is no corolla ; the nectarium is com- 
posed of bifid bristles ; the capsule is quin- 
quangular, quinquelocular, quinquevalved, 
and polyspermous. There are three species, 
herbs of Arabia and the south of Europe. 
GLIRES, the name given by Linnaeus to 
the fourth order of the mammalia ; the cha- 
racter of v hich is, fore-teeth cutting, two in 
each jaw; no tusks; feet with claws formed 
for running and bounding; food, bark, roots, 
vegetables, &c. which they gnaw. 'Hie or- 
der includes ten genera, viz. the hystrix, 
cavia, castor, mus, arctomys, sciurus, my- 
oxus, dipus, lepus, and hyrax. 
GLISTER, in surgery, the same with 
clyster. 
GLOBBA, a genus of the monogynia or- 
der, in the monandria class of plants. The 
corolla is equal and tritid, the calyx trifid 
above, the capsule trilocular, with many 
seeds. There are four species, herbs of the 
East Indies. 
GLOBE, in geometry, a round or sphe- 
rical body, more usually called a sphere. See 
Sphere. 
Globe is more particularly used for an ar- 
tificial sphere of metal, plaister, paper, ©r 
other matter, on whose convex surface is 
drawn a map or representation either of the 
earth or heavens, with the several circles con- 
ceived thereon. 
Globes are of two kinds, terrestrial and ce- 
lestial ; each of very considerable use, the 
one in astronomy, and the other in geogra- 
phy, for performing many of the operations 
in an easy obvious manner, so as to be con- 
ceived without any knowledge of the mathe- 
matical grounds of those arts. The funda- 
mental parts, common to both globes, are an 
axis, representing that of the world, and a 
spherical shell or cover,, which makes the 
body of the globe, on the external surface 
of which the representation is drawn. 
The- globes commonly used are composed 
ofplaisterand paper in the following manner. 
A wooden axis is provided, somewhat less 
than, the intended diameter of the globe, and 
into the extremes two iron wires are driven 
for poles: this axis is to be the beam or basis 
of the whole structure. On the axis are ap- 
plied two spherical or rather hemispherical 
caps, formed. on a kind of wooden mould oi 
block.. These caps consist of pasteboard or 
10 
G L O 555 
I paper, laid one lay after another on the 
mould, to the thickness of a crown-piece; 
after which, having stood to dry and embody, 
making an incision along the middle, the two- 
caps thus parted are slipped off the mould. 
They remain now to he applied on the poles 
of the axis, as before they were on those of 
the mould; and to fix them in their new 
place, the two edges are sewed together 
with packthread, &c. 
r I he rudiments of the globe thus laid, they 
proceed to strengthen and make it smooth 
and regular. In order to this, the two poles 
are hasped in a metalline semicircle of the 
size intended ; and a kind of plaister made of 
whiting, water, and glue, heated, melted, and 
incorporated together, is daubed all over the 
paper surface. In proportion as the plaster 
is applied, the ball is turned round in the 
semicircle, the edge of which pares oil’ what- 
ever is superfluous, and beyond tlxe due di- 
mension, leaving the rest adhering in places 
that are short of it. After such application 
of plaister, the ball stands to dry ; which done* 
it is put again in the semicircle, and fresh 
matter applied : thus they continue alter- 
nately to apply the composition and dry it, 
till the ball every where accurately touches 
the semicircle ; in which state it is perfectly 
smooth, regular, and complete. 
The ball thus finished, it remains to paste 
the map or description on it. In order to 
this, the map is projected in several gores or 
gussets, all which join accurately on the sphe- 
rical surface, and cover the whole ball. To 
direct the application of these gores, lines arc- 
drawn by a semicircle on the surface of the 
ball, dividing it into a number of equal parts- 
corresponding to those of the gores, and sub- 
dividing those again, aaswerably to the lines 
and divisions- of the gores. 
The papers thus pasted on,, there remains- 
nothing but to colour and illuminate the 
globe, and to varnish it, the better to resist 
dust, moisture, &c. The globe itself thus- 
finished, they hang it in a brass meridian, 
with an hour-circle and a quadrant of alti- 
tude, and thus fit it into a wooden horizon. 
GLOBES-, use of. By the assistance of 
the globes a great number of curious, useful, 
and entertaining problems are worked, some 
of which we shall proceed to describe. The 
globe consists of several parts: as (1) the two- 
poles, being the ends of the axis on which 
the globe turns, representing the diurnal mo- 
tion of the earth, and the apparent diurnal 
motion of the heavens. (2) The brazen me- 
ridian, on which are marked the degrees- 
from the equator to the poles. (3) The 
wooden horizon or frame that supports the- 
whole globe, on which are drawn several, 
circles, as that on which the signs of the zo- 
diac are marked ; that containing the calen- 
dar or days of the month which correspond: 
to the several degrees of the zodiac;, and 
that on. which. are delineated the 32 points of 
the compass. (4) The hour-circle, divided- 
into twice 1.2. hours, representing the divi- 
sion of time for the day ami the night. And, 
(5) a thin slip of brass, called the quadrant 
of altitude, useful in several problems to mea- 
sure the -distances and directions- of the places* 
from each other.
