are reduced to inches and a correction of —.190 in. applied 

 to obtain the vahies pubHshed in this vokime. 



The results thus obtained are for station level, not corrected for 

 gravity. If it is wished to correct these values for gravity 

 and reduce the pressure to sea level, it is necessary to apply 

 a correction of +.016 in. for gravity and +.1/5 in. for 

 height above mean sea level, making a total correction of 

 + .191 in.
