wife called Sibyls, as the Delphic Sibyl, the Cumaan Sibyl, &c.

The feventh Conftellation, when the Sun arrives at the Autumnal Equinox, is expreffed by the Ballance, or Pair of Scales in Equilibrio, because Days and Nights are then every where equal.

October is often a fickly Seafon, when the Surfeits got in the hot Months of the Summer produce their fatal Effects; the Symbol is therefore the Scorpion, who wounds with a Sting in his Tail, as he is going away.

The Diverfion of Hunting, which is chiefly followed after the Fall of the Leaf, is fignified by the Sagittary or Archer; which the Greeks have probably changed into the fabulous Centaur.

As the Crab, which goes backward, fignified the Summer Solstice, when the Sun begins to go back from the Northern Tropic, fo the Goat, which delights to browse up Hill, is the Symbol of the Winter Solstice, when the Sun begins to afcend from the Southern Tropic, and is continually mounting higher and higher for the enfuing half

As for the rest of the Conftellations, which are out of the Zodiac, the Bulk of them were formed by the Grecians, who imitated the Egyptians in giving the Names of Men and Animals to Parcels of Stars; but without any fuch particular Reasons as the Egyptians had for naming the twelve Signs of the Zodiac.

This is the Subftance of what that Author fays upon this Subject.

This I dare boldly tell,

'Tis fo like Truth, 'twill serve our Turn as well.

The Ufe of the Globes.

OBLEM I. To find the Latitude and Longitude of any given Place on the Terreftrial Globe.

Bring the Place to the graduated Edge of the brazen Meridian; then the Degree marked on the Meridian over it fhews its Latitude; and the Degree of the Equator,

then under the Meridian, fhews its Longitude. Hence, if the Latitude and Longitude of any Place be given, the Place is eafily found, by bringing the given Longitude to the Meridian, for then the Place will lie under the given Degree of Latitude upon the Meridian,

PROB. II. To find the Distance of any two Places on the Terreftrial Globe.

Lay the Quadrant of Altitude on both Places; or take the Distance between them with a Pair of Compaffes, and apply it to the Equator. The Number of Degrees on the Quadrant between them, or betwixt the Feet of the Compaffes on the Equator, reduced to Miles, (that is, 70 to a Degree) fhews their Distance in Miles. In the fame manner the Distance of any two Stars may be found on the Celestial Globe, in Degrees, tho' not in Miles *.

PROB. III. To find the Antaci, Periaci, and Antipodes, of any given Place.

Bring the given Place to the Meridian, and obferve its Latitude. The fame Latitude, counted towards the contrary Pole, and under the fame Meridian, fhews the

* Because not knowing their Distance from us, we cantist tell the value in Miles of their Orbits.

Place

Place of the Antaci. Keep the given Place under the Meridian, fet the HourIndex to 12 at Noon, then turn to the Globe till the Index Points to 12 at Night, and the Place that is now under the fame Degree of the Meridian, that the first given Place was, is that of the Periaci. The Antipodes of the first Place are now under the fame Degree of the Meridian that the Antaci were before.

PROB. IV. To rectify the Globe for the
Latitude, Zenith, and Sun's Place.

1. For the Latitude; Elevate the Pole above the Horizon, according to the Latitude of the Place.

2. For the Zenith; Screw the Quadrant of Altitude on the Meridian, at the given Degree of Latitude, counting from the Equator towards the elevated Pole.

3. For the Sun's Place; Bring the Sun's Place in the Ecliptic (found in the Kalendar on the wooden Horizon, against the Day of the Month) to the Meridian, and fet the Hour-Index to twelve at Noon.

PROB. V. The Hour being given at any Place, to find what Hour it is in any other Part of the World.

Bring

Bring the given Place to the Meridian, and fet the Hour-Index to the given Hour; then, by turning the Globe, bring any Place to the Meridian, and the Index will point to the Hour at that Place.

PROB. VI. The Day and Hour at any
Place being given, to find where the
Sun is in the Zenith at that Hour.

Bring the Sun's Place to the Meridian, and note the Degree over it (which is the Sun's Declination at that time;) then bring the given Place to the Meridian, and fet the Index to the given Hour; turn the Globe till the Index points to 12 at Noon, and the Place on the Globe, which lies under that Degree of the Meridian that was before noted, has the Sun juft then in its Zenith.

PROB. VII. The Day and Hour being given, to find all thofe Places of the Earth where the Sun is Rifing, Setting, or Culminating; and alfo where it is Day-light, Twilight, or Darknight.

Find the Place where the Sun is vertical at the given Hour (by PROB. VI.) rectify for the Latitude of that Place, and bring it to the Meridian. Then all the Places that
