Bifilar. Observed 2™ after the Declination, £=0-000140. 



Balance. Observed 3"> after the Declination, 4=0-0000085. 



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

 :tometers. 



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

 >preciable, the micrometers were not altered. 



July 24d 18h 10m. A minute insect was seen creeping over the west cross-plate of the balance magnet, which, perhaps, has caused some motion in the needle ? 

 18h 45m the box was lifted from the instrument and the insect was removed.
