A bstract This paper is divided into 6 sections, of which an enumeration will constitute its abstract: (1) introduction; (2) trigonometric criteria for determining whether a given point Q lies on the great circle passing thru 2 other given points, A and B , of north pole P (3) and (4) methods of determining the geographic coördinates of pole P (5) determination of the distance of a given point R from the great circle; and (6) determination of the coördinates of point S , the point on the great circle closest to the given point R . Several subtopics are discussed in the notes to the paper.
