By the second method the curve is traced by what is known, in French, as cheminement, and differs from the first in that the operator, instead of directing the work from one point, goes forward as it proceeds. It is based on the principle that if the perimeter of a circle is divided into equal parts the abscissse are all equal to each other. In Fig. 4 the curve is equally divided in r, (?,
