Plainly a borderline closed curve of the figure which has the hole surrounds inwardly all figures except the figure itself and figures which its other borderline closed curves surround inwardly respectively; yet the borderline closed curve surrounds outwardly the figure and those figures which the other borderline closed curves surround inwardly respectively, therefore we need merely to prove all figures at a planar map from any spherical map, to wit O.
