CHAP. 1.

Of the Definition, Division, Method, &c, of GEOGRAPHY.

T hath been an antient Custom for those that fully treat of any Art, or Science, to premise somewhat of it's Origin, Nature, Constitution, Sec. And this Procedure is not improper, provided it be clear of all sophistical Equivocation; because from such Preliminaries the Reader may conceive an Idea of the Work, or at least the Substance thereof, and ib proceed more advisedly therein. We stiall therefore here offer a few Particulars as to the Nature, Use, and Design of Geography. VOL. I. B The The Definition of Geography.

[graphic]

GEOG RAPHT is that part of mixed Mathematics^ which explains the State of the Earth, and of it's Parts, depending on Quantity, viz. it's Figure, Place, Magnitude, and Motion, with the Celestial Appearances, &c.

B Y some it is taken in too limited a Sense, for a bare Description of the several Countries; and by others too extensively, who along with such a Description would have their Political Constitution. But the Authors who proceed thus are excusable, because they do it only to excite and delight the Reader, who might otherwise be the less attentive to a bare Enumeration and Description of the Countries, without some Knowledge of the Manners, and Customs of the Inhabitants.

The Division of Geography.

W E divide Geography into General and Special, or Universal and Particular. Golnitzius fays, Geography is to be explained externally and internally; but .these Terms are improper, and ill chosen, Universal and Particular being much more pertinent. We call that Universal Geography which considers the whole Earth in general, and explains it's Properties without regard to particular Countries: But Special or Particular Geography describes the Constitution and Situation of each stngle Country by itself which is twofold, viz. Chorographical, which describes Countries of a considerable Extent; or Topographical, which gives a View of some place or small Tract of the Earth.

I N this Book, we shall exhibit Universal Geography, which may be divided into three Parts, Absolute, Relative, and Comparative. In the Absolute

Part

Part we shall handle what respects the Body of the Earth itself, it's Parts and peculiar Properties; as it's Figure, Magnitude, and Motion; it's Lands, Seas, and Rivers, &c. In the Relative Part We shall account for the Appearances and Accidents that happen to it from Celestial Causes: and, lastly, the Comparative Part shall contain an Explication of those Properties, which arise from comparing different Parts of the Earth together (a).

The Subjetl of Geography.

THE Object, or Subject, of Geography is the Earth ; especially it's Superficies and exterior Parts.

The Properties of Geography.

THE Things which seem to be most worthy of Observation in every Country are of three kinds, viz. Celestial, Terrestrial, and Human. The Celestial Properties are such as affect us by reason of the apparent Motion of the Sun, and Stars. These are eight in Number: 1. The Elevation of the Pole, or the Distance of a Place from the Equator. 2. The Obliquity of the Diurnal Motion of the Stars above the Horizon of that Place. 3. The Time of the longest and shortest

Heat, Cold, and the Seasons of the Tear v with Rain, Snow, Wind, and other Meteors: and tho' these may seem Terrestrial Properties, yet because they chiefly depend upon the Motion of the Sun, and the four Seasons of tne Year, we have reckoned them among the Celestial Matters. 6. The Rising, Appearance, and Continuance, of the Stars above the Horizon. 7. The Stars that pass thro' the Zenith of a Place. 8. The Celerity of the Motion with which, according to the Copernican Hypothesis, every Place constantly revolves. And according to Astrologers a ninth Property may be added; for they assign some Country or other to every one of the twelve Signs of the Zodiac, and the Planets which are Lords of these Signs; but such imaginary Qualities seem superstitious and vain to me; nor do I perceive any reasonable Foundation for them (a). Thus far the Celestial Properties.

W E call those Terrestrial Properties that are observed in the Face of every Country; which are ten in Number. 1. The Limits and Bounds of each Country. 2. It's Figure. 3. It's Magnitude. 4. It's Mountains. 5. It's Waters, viz. Springs, Rivers, and Bays. 6. It's Woods and Defarts. 7. The Fruitfulness and Barrenness of the Country, with it's various kinds of Fruits. 8. The Minerals and Fossils. 9. 7i£i? living Creatures there. 10. The Longitude of the Place: which might be comprehended under the first of these Properties.
