Excerpt from The Texas Mathematics Teachers Bulletin, 1924, Vol. 11

Another regular subdivision of the right angle and one concerning which mathematical books are singularly silent is that which goes by the ambiguous title, the point. The circumference is divided into thirty-two equal divisions, the angle of one-eighth of a right angle being then called the point. This is one of the easiest methods of obtaining an angle, when once a pair of mutually perpendicular diameters have been drawn, only bisection being employed. Fractions of a point when required, are measured in the same spirit, in halves, quarters, eighths, and so forth. The reason that this subdivision is so seldom mentioned is probably because it is so extensively identified with the compass and is so seldom used for accurate measurement. The notation used with a compass is self-consistent but hardly simple to an average layman who would usually be hard put to it to box the compass in approved nautical fashion. Another method of subdividing the point, and one well adapted to careful work leads to the French mil, which will be men tioned shortly.
