Abstract : Formulas for calculating normal heights, normal heights differences and theoretical closing-errors of pirit-levelling polygons have been obtained, which formulas may ensure an accuracy of the order of a millimeter in mountainous regions. Methods are proposed for computing the heights of points located in the interior of the Earth. It is shown that the Vignal's system of heights was obtained irrespectively of the problem of determining the total height of points on the physical surface of the Earth above the reference ellipsoid. Vignal's heights system is not identical with the system of mormal heights. In spite of the widely-spread opinion, the method of height determination proposed by Rune is not identical with that of normal heights determination. The results of computations according to Rune's formulas depend on the path of the levelling line. Some inaccuracies in articles by Bokun and Chojnicki are mentioned. (Author)
