The western antipleion of 1902 is not the southeastern antipleion of 1901. The consecutive maps show that the center of the anti])leion remained nearly stationar}' over tlie Atlantic, east of Georgia or South Carolina, and that, at the end of the year, the negative area ex- tending over the States moved eastward. The following diagram (Fig. 33) shows the successive positions of the quasinormal line for the consecutive maps of November, 1901,-October, 1902, until Januaiy-December, 1902. The maps show an interesting feature concerning this antipleion. Its disappearance from the map was preceded by a progressive shrinkage followed by an expansion. The shrinkage began with April, 1901,-March, 1902, and continued until June, 1901,-May, 1902, when the quasinormal line lay from Washington over Louisville and Memphis towards Yicksburg; then, the negative area. Fig. 32.—Successive positions of the quasinormal line Fig. 33.—Proijressivc displacements of the antipleion of 1901 increased again progressively until November, 1901,-October, 1002, and was followed by the eastward movement shown on the diagram. The consecutive maps do not give a satisfactory account of the forma- tion of the negative wave which, on !he map of 1902, extends between the pleions of Canada and Mexico. The regional departure maps do not show the existence of the two pleionian centers of 1901 (Fig. 23) until towards the end of the year. The movement of separation begins with December, 1901,-November, 1902, and corresponds to the rapid drift of the eastern antipleion towards the southeast. The western antipleion of 1902 (Fig. 24) came from the southwest and spread out, progressively^ over the entire area of the United States. 1902-1903. Evidently the quasinormal line of the consecutive maps is not the same as the quasinormal line of the departure maps from
