the latter is divided from the fame point into 24 hours. 
Upon the foot of the globe there is often put a com- 
p:.fs, by which the brazen meridian may be fet north 
and foiith.—See figures of a pair of globes on an im¬

Euclid, at the end of his twelfth book, fliews that 
fpheres or globes are to one another in the triplicate ra¬ 
tio of their diameters, that is, their Iblidities are to one 
another as the cubes,of their diameters. And Archi¬ 
medes determines the real magnitudes and meafures of 
the furfaces and folidities of fpheres and their fegments, 
in his treatife de Sphcera et Cylindro ; viz. i. That the 
fuperficies of any globe is equal to 4 times a great circle 
cf it. 2. That any fphere is equal to § of its circum- 
Icribing cylinder, or of a cylinder of the fame diameter 
and altitude. 3, That the curve furface of the fegment 
of a globe, is equal to the circle vvhofe radius is the line 
dra-ivn from the vertex of the fegment to the circumfe¬ 
rence of the bafe. 4. That the content of a folid feblor 
of the globe, is equal to a cone whofc altitude is the ra¬ 
dius of the globe, and its bafe equal to the curve fuper¬ 
ficies or bafe of the feftor; and from hence are eafily 
deduced thel'e prattical rules for the furfaces and foli¬ 
dities of globes and their fegments ; viz. i. For the fur- 
facc of a globe, multiply the fquare of the diameter by 
3'X4 i 6; or multiply the diameter by the circumference. 
2. For the folidity of a globe, multiply the cube of the dia¬ 
meter by •5,236 (viz. i of 3*1416); or multiply the fur- 
face by i of the diameter. 3. For the furface of a fegment, 
multiply tlie diameter of the globe by the altitude of 
tlie fegment, and the prodiuSi: again by 3'1416. 4. For 
the folidity of a fegment, multiply the fquare of the diame. 
ter of the globe by the difference between 3 times that 
diameter and 2 times the altitude of the fegment, and 
the produbi; again by ‘5236, or ^ of 3-1416.—See the 
article Sphere. And for the molt approved methods of

Belides the terreftrial and celefiial globes above de- 
feribed, there are others conllrudted or mounted for the 
following purpofes ; i. A globe to fiiew the phenomena 
of the tranlit of Mercury and Venus over the Sun. 2. 
A "globe to Ihew the phenomena of lolar and lunar 
eclipfes on all places of the terreilrial globe, called an 
eclipfareon. 3. A globe to fhew the nature and manner 
of the preceliion of the equinoxes, and tliereby the dif¬ 
ference between the fidereal and tropical years, as alfo 
the apparent and diredt motion of the fixed liars. 4. 
A celeltial globe, with a telelcopc to fix on the north 
pole of the globe occalionally, with a divided arc, &c. 
&c. An apparatus invented by Adams for obferving any 
celeftial body, and thereby, in an inllantaneous manner, 
obtaining all the particulars of any phenomena prefent- 
ing themfelves in the heavens. 5. A lunar globe, or 
the felenegraphia, invented by Mr. John Ruffel, R. A. 
forming an apparatus for exhibiting the phenomena of 
the moon, and the ufeful purpofes to which it may be 
applied.—For a feries of ufeful problems on the terref-

GLOBULA'RIA, y [fo named by i ournefort from 
the flowers growing many together in form of a little 
globe or ball.] In botany, a genus of the clafs tetran- 
dria, order monogynia, natural order of aggregatae, (ly- 
fimachi^, JuJ.) The generic characters are—Calyx: 
common perianthium imbricate with fcales the length 
of the difk and equal ; proper one-leafed, tubular, five- 
cleft, fharp, permanent, (four or five-toothed, the teeth 
briftle-fliaped and acuminate, Gartner.) Corolla: uni- 
verfal nearly equal; proper monopetalous, tubular at 
the bafe; border five-parted; upper lip very narrow, 
two-parted, fliorter; lower of three larger equal feg¬ 
ments. Stamina: filaments four, fimple, the length of 
the corallule; antherae diftindl, incumbent. Piftillum ; 
germ ovate, fuperior; ftyle fimple, the length of the 
Itamens; ftigma obtufe. Pericarpiuin: none; proper 
calyx converging, inclofing the feed. Seeds: folitary, 
ovate. Receptaculum : common oblong, feparated by 
chaffs.— EJfential CharaBer. Calyx common (or none, G.) 
imbricate; proper tubular, inferior; corollets the upper 
lip two-parted, lower three-parted; receptacle chaffy.. 
Species, i. Globularia longifolia, or long-leaved glo- 
bularia: ftem flirubby ; all the leaves linear-lanceolate, 
quite entire; headsaxillary. Thefe have all perennial 
roots. Stem fhrubby, or herbaceous, fimple, ufually 
with one head of flowers at the top; ftem-leaves fmall, 
or fcarcely any. The leaves of all the globularias are 
dry black; the corollas blue. The firft fpecies rifes 
much higher than the fecond, having a hard white wood 
with a large pith and a fcabrous light brown or grey 
bark; the branches towards tiieir ends very thick fet 
with leaves, without any order; they are two inches 
long, and a third part of an inch broad in the middle ; the 
nerves ycllowifli green. Flowers fmall, blue, in round 
heads. Native of Madeira; flowers in July and Auguft. 
2. Globularia alypum, or three-tooth-leaved globula¬ 
ria : ftem flirubby ; leaves lanceolate, three-toothed, and 
entire ; heads terminating. This has a hard woody ftem, 
about two feet high, with many woody branches, befet 
with leaves like thofe of the myrtle. The flowers are 
produced on the tops of the branches in a ball, and are 
of a blue colour. Native of the fouth of Europe : as 
about Montpellier, and in many parts of Narbonne and 
Provence ; Valentia, and feveral other places in Spain; 
Nice, and the fea-coaft of Uneglia ; alfo in Barbary. It 
flowers from Auguft to November. From the violent 
purging quality of this fhrub, it acquired the name 
of herba terribilis, herb terrible; but, in the abundance 
of purging medicines that we polTei's, this is feldom if 
ever tiled. 
3. Globularia bifna.garica: ftem flirubby; root-leaves 
wedge-fliaped, retufe; ftem-leaves lanceolate. Stem 
fhrubby. Leaves rigid, thofe next the root-leaves 
rounder and cordate, but the ftem-leaves pointed. 
4. Globularia vulgaris, common globularia, or blue 
daily: ftem herbaceous; root-leaves three-toothed ; ftem- 
leaves lanceolate. Stem flender, upright, covered with 
leaves, from an inch and a half to fix inches in height, and 
fometimes more, fbmewhat angular, very fimple, fhiooth, 
one-flowered. Root-leaves numerous, like thofe of the 
daify, but tliicker. Scopoli obferves, that the leaves of 
the former year are eniargiiiate, with a dagger-point in
