§. Appropriate Contrivances — exemplified in the first proposition of Euclid.

Take a straight rod of any convenient material, and any convenient length. Placing it suppose on a sheet in any direction — suppose that which is parallel to the breadth of your body as you sit. Keep Keeping one end of it fixt, turn it round till it has come back into the position in which it was just before the motion begun. If suppose the rod smeared at bottom with any black coloured matter which by coming off will leave a mark the whole way on the paper. In form This mark will be what the figure called a circle: of which the edge all round is called the circumference: and the point at the fixt end, the centre. Stop the rod any where during its course, you will find the mark made by it bounded by a straight line. From a Greek word This line is called a semidiameter, or a radius: which in Latin [+] [+] Latin means a ray of light: or the spoke of a wheel: Stop next {=}2 [+]2 at the point at which the rod is in the same direction, as when you stopt first. You will [+]2 [+]3 find the another line continued in the same direction with the first and making one line with the first This compound line is called the diameter of the circle: from two Greek words one meaning the radius the other the measure.
