SYSTEM, in Mustek, is the Extent of a cer-tain Number of Chords, having its bounds towardthe Grave and Acute, which hath been differentlydetermin’d by the different Progress made in Mu-stek, and according to the different Divisions ofthe Momclmd.

The System of the Ancients, was composed offour T etrachords, and one Supernumerary Chord, thewhole making Fifteen Chords.

SYSTEM properly is a regular orderly Collecti-on, or Composition of many things together.

I the Earth by Observation, promise that he wouldexplain a System of die World, differing in manythings from any then known, and yet exactly a 'greeable to Mechanical Principles. Which Systemhe there fays, depends on these three Supposi-tions, vi%.

First, That all the Heavenly Bodies have a gra-vitating or attracting Power towards their ownCentres, whereby they attract not only their ownParts, and keep them from flying off from thew,but also all other Celestial Bodies within the Sphereof their Activity.

Secondly, That all Bodies put into a direct andsimple Motion, will so continue to move forwardsin a strait Line, till they are by some other moreeffectual Power bent or deflected into a Motion,which describes some Curve Line.

Thirdly, That these attractive Powers aremuch the more powerful in operating by how muchthe nearer the Body wrought upon, is to their ownCentres.

All which is abundantly confirmed in Mr. lfi 4CNewton's Admirable Principia Philosophic Mat bentt"tica.
