Table 82. 

 GRAVITY. 



In this table the results of a number of the more recent gravity determinations are bi^ught together. They serve to 

 show the degree of accuracy which may be assumed for the numbers in lable Si. In general, gravity is a little 

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