Balance. Observed Z^ after the Declination, A-=0-0000085. 



The temperature of the biiilar and balance magnets, and the observers' initials, will be found at the corresponding hours in the Hourly 

 Observations of Magnetometers. 



When double commas („) occur in the column for the balance magnetometer, the needle was examined, and no change from the previous 

 observation being appreciable, the micrometers were not altered.
