Declination. Torsion removed, circle reading, — Sept. 4* l*", 53°* ; 12'' 23^, 82°. 

 BiFiLAR. i=0-0001205. Balance. i=0-000013* approximately. 



* Sept. 1'' — S*. The Balance magnet removed in order to determine its temperature correction : at 4* l*" it was vibrated horizontally 

 he Declinometer box, and afterv^ards re-adjusted.
