March 144, Torsion of Declinometer thread examined. Circle moved 54°. Left reading 276°. Mr Russell conceived this 
torsion to have taken place on removing the magnet in order to make the Dip observation March 114 6, when most probably from 
the thread getting loose for a moment the fibres took a different disposition inter se. 
March 254 65, On removing the detorsion bar from the Declinometer after the Dip observations, the suspension cylinder was 
accidentally let slip. Brass bar suspended throughout March 264, and torsion removed. Circle left reading 326°. 
March 254 16h, Declinometer employed in making intensity observation. 
March 254 2023, Observatory being cleaned. 
Observations of the declination at these hours have been corrected for torsion by
