Taking the mean of the two sets of results for Tokio, wc have for ihu U 

 pcinliiliini, the time of a single oscillation 



f = 1.0o073isec. ± 0.000001Ü 

 and for the C pendulum

Now the vaino of rj for Tokio according to I'rof. MendfidiaTi* d«-liT- 

 inination is 070.85 1- ± 0.0011, the units being the centimetro and the imaii 

 solar second. From the data thus furuishud, wo havo deduced the following 

 values of g for Naha and Kagoshima :

The above results are both of llicin slightly greater than those obtained 

 by calculation from appro.xiuiato formuliC.
