 BiriLAR. i=0-0001205. Balance. i=0-000014* approximately. 



Aug. 21d Ob— 4h. Magnet with short scale in the Declinometer. 



Aug. 21d 71i. Deflection magnet vibrated in the Declinometer box. 



Aug. 23d Ob— 24d 6h. Magnet with short scale inserted in the Declinometer "box, and the Balance magnet removed, in order to determine its temperature cot 

 rection. The Declination and Bifilar readings are corrected tor the effect of the Balance. 



* Aug. 24d 7h. Balance needle vibrated horizontally in the Declinometer box, and afterwards adjusted. 



Aug. 30d 4h— Sept. 12d 22h. Magnet with short scale in the Declinometer box, while the magnet with the long scale was used in the Extra Declinometer box fo 

 temperature experiments and intensity observations.
