The results of the pendulum observations are given in Table L and redistributed 

 in Table LI. 



TABLE 



Thus, the probable error of a single result : 



e & --= 7-2x1 0- 7 sec. 

 e- --= 8-2 

 ^ == 3-1 

 e m =4-4. 



The probable error of the mean result : 



p b -= 3-2 x 1CT 7 sec. 

 P-, =3-7 

 Pn ==1'4 



l>,n == 2-0. 



Tables LII and LIII are also formed in order to get an estimate of the accuracy 

 of the comparison between clock and pendulum.
