Abstract
Succeeding to the 1st and the 2nd reports, the results obtained from the investigations in the central part of Kagosima-bay and in the sea-fronts touching the sea shore both on Satsuma and Osumi Peninsulas were summarized here as the 3rd report: -1. In the central part of the bay almost all the errors are fixed to be western ; maximum 4°W local attraction measured. 2. In the southern coast of Satsuma-peninsula, almost all of them are western; maximum 3.5°W local attraction measured. 3. In the eastern coast of Osumi-peninsula the errors are supposed chiefly to be western ; the figures being not only generally small, compared with those in Satsuma peninsula, definite but too complicated and obscure to draw any conclusion from them. 4. As to the magnetism-color of the land around the Kagoshima bay, on Satsuma peninsula side it is blue, and on Osumi peninsula side, red ; the former being supposed to be stronger ; the cause of which might reasonably be attributed to the distribution of the iron-sand and the mineral-deposits.
