VVHereas in the French, all the Defini∣tions which needed all the Propositi∣ons, as also all those uses, our Author thought fit to Illustrate by Schemes, were done in the Book in wood, here they are in Copper plates to be placed at the end of the Book. The Definitions and uses are in the Plates marked with Arith∣metical Charactars or Ziphers; but the Propsi∣tions in Alphabetical Ziphers at the begining of the Book, or at least when you come to the first Definition, you are ref••rred to the number of the Plate, in Which you shall find the Scheme pro∣per thereto, as also the Def Prop. and uses belonging unto the Book, unless the Plate could not contain them, and then you are referred to the next Plate; whereon the head thereof you shall find the Book it belongeth to, and the Propo∣sitions, or uses, continued in their order.
