BiriLAk. Observed 2™ after the Declination, k=0-000140. BALANCE. Observed 3™ after the Declination, s=0:000010. 
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. : " 
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. 
March 204 155. Extra Observations made.
