TABLE XXXIV. 



In Table XXXV below, are set out the differences and their squares for the indi- 

 vidual pendulums. 



TABLE XXXV. 



The probable errors of the individual results are therefore 



e . = 8-4X1CT 7 sec. 



e- = 3-9 



e 2 i == 6-0 



e,,, - 5-3 XlO- 7 sec. 



and 



p : , -= 2-7 XlO- 7 sec. 



p- =1-5 



Pa = 2-3 



p,,, == 2-0 XlO- 7 sec. 



The values of e, and p t above are somewhat better than those deduced from the 



observations of Series " B," and it is clear that a certain -ain in accuracy has been 

 achieved.
