TABLE LXXIT. 



For the calculation of the value of gravity at the field stations the formula 



is used, where g s and g p are the values of " g" at the station and at Potsdam, respectively, 

 and S s and S^, are the corresponding periods of swing. 



The value of g p is taken as 981-292 cms. per sec. per sec, for pillar 32 in the 

 Pemlelsaal at the Potsdam Geodetic Institute. 



Table LXXIII is formed for each pendulum by the use of this formula.
