Biritar. Observed 2™ after the Declination, k=0-000140. BaLancr. Observed 3™ after the Declination, k=0000010, 
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. 7 
When double commas (,,) occur in the column for the balance magnetometer, the needle was examined, and no change from the previous 
position being appreciable, the micrometers were not altered.
