Precise gravity measurement was carried out again at 13 stations, where gravity difference from the Gravity Station of Geophysical Institute of Kyoto University is smaller than 1 mgal, along the levelling route of the Kui Peninsula, by means of 3 LaCoste &" Romberg gravimeters (model G) in March 1972. Through the back and forth measure-ment (3 days per each way), its accuracy was obtained to be about ±0.01 mgal. Prior to the measurement, it was examined whether the reading value is affected by voltage change of the connecting battery or not. Its results are also described in the present paper.
