Declination. Torsion removed, circle reading, — Dec. 5'^ 3^, 113J°, 108°* ; 14* S^, 115° 

 BiFiLAij. ^=0-0001300. Balance. A=0-000014 approximately. 



Dec. 5<i 3^. After removing the torsion from the suspension thread of the Declinometer, the magnet, being too near the copper ring, 

 was wound up a little, and the torsion again removed as above. 



Dec. 7*1 19^. A mistake in the time of an hour was made this morning, which was not discovered till 8^ 40", when an observation 

 was made. 



l>ec. 14 1 . Removed the inner box from the Bifilar Magnetometer for comparisons of thermometers. See Introduction.
