Table 3 A. Corrections to table 2 a for values of the acceleration of gravity at sea-level 



different from 9.80. 



Example, tables z a and j A. 



Column 1. Heights above sea-level. 



2. Values of'table 2 a for the heights 4000, 11000, 

 19000, 32000. 



3. Values of proportionality table for the heights 

 871, 492, 601, 416. 



4. Corrections from table 3 A for -=9.8197 at sea- 

 level and for the heights of column 1. 



5. Sum of numbers in columns 2,3, and 4, giving the 

 dynamic heights corresponding to the geometri- 

 cal heights of column 1.
