Table 113. 



GRAVITY. 



In this table the results of a number of the more recent Rravity determinations are brought together. They serve to 

 show the degree of accuracy wliicli may be assumed for the numbers in Table 112. In general, gravity is a little 

 lower than ihe calculated value for stations far inland and slightly higher on the coast line.
