Tim?, from tlie formula 



* ;/ = 9SO.G05 - 2. 5028 cos 2 ;i - 0.000003 li 

 we get 



for Xalia, g = 979.04 cms. per sec. per sec, 



for Kagoslaima, g = 979.49 ,, ,, ,, 



The formula 



t r/ = 9S0'G3-2-55:3 cos 2 A 

 gives nearly the same results as above. 

 Again tlie formula 



+ <7 = 97S-O72S + 5'0S7ü siu-f5 

 gives 



for Xalia, f/ = 979'06 cms. per sec. per sec, 



for Kngosliima, (7=:979'47 „ „ ,, 



Again the formula 



§ r/=32-0SS(l +0-005133 sin- ;i) 

 ■which is iu terms of the British absolute units gives, iu terms of the French 

 units, 



for Naha, (/ = 979'00 cms. per sec. per sec, 

 for Kagoshima, <7 = 979'39 ,, ,, ,, 



Xow all these values are slightly smaller than those actually oVitained 

 fr'om experiments. Such discrepancies however, cannot much detract from 

 the merit of the experimental work, since the formula are all of them only ap- 

 proximate, and the comparisons of the values must be considered as the test of 

 the formula rather than the test of the work.
