METEOROLOGICAL TABLES. 



Table I M. Normal decrease of the acceleration of gravity with the height. 



Table 2 M. Normal value of the acceleration of gravity at sea-level. 



Example 1 : Latitude 42 27', table 2 m gives 9-8039 



Height 18429 meters, table 1 m gives 0.0569 



Gravity at latitude 42 27', height 1S429 meters.. 9.7470 



Example 2 : Measured gravity at the earth's surface. 9.7S81 

 Height of station 1470 meters, table 1 m gives 



(sign reversed) -\- 0.0045 



Gravity reduced to sea level 9-7926
