(1) Polarity was found to be quite antagonistic ; in the northern side of Sakurashima it being ‘Westerly’, while in the southern side of the same islet it being ‘Easterly’. (2) The maximum value obtained in the measuring was4.2° in the north side, and 3.8° in the south side, respectively ; the observational error was assumed to be ±0.2°. (3) The ‘local-attraction’ was assumed to be owing its origin to the residual thermo magnetism of the lava issued at the volcanic eruption of the islet Sakurashima ; almost whole of the islet is supposed to be in possession of blue (-) polarity. (4) The assumption of the existence of the ’local-attraction’ may be justified by the correlationship confirmed between the measured attraction and the ‘local-attraction’.}, pages = {19--29}, title = {鹿児島湾における地方磁気に関する研究II : 桜島周辺の地方磁気について}, volume = {14}, year = {} }
