BIFILAR. Observed 2™ after the Declination, k—0:000140. 
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. 
Jan, 224115 25m. Declination magnet commenced moving eastwards. 115 39™. Bifilar reading, 569°0. 11 44™. Bifilar reading, 5740
