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

 Observations of Magnetometers. i 



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

 observation being appreciable, the micrometers were not altered. ,
