In connection with the precise levelling done this summer at volcano Asama, latitude determinations were made by the writer at Koasama and Boroku triangulation points, both of which are situated on the eastern slope of the volcano. The reason for doing it was to determine the present shape of the geoid, in order to obtain data to enable us to distinguish the change in shape of the geoid from true deformations of the volcano, when relevelling the mountain in the future. The results of the observation are 36°24′36″・519±0″・052, Koasama, 36°22′59″・75±0・21, Boroku. Besides these observations, a rough estimate of the longitude was made at Koasama, giving 9h14m15s 424±0s 125. These values give deviations of vertical(A-G) of the following magnitudes : Koasama: {12″07 in latitude; -Xs 260 in longitude;} Boroku : 3″79 in latitude.
