DECLINATION. Torsion removed, circle reading,—Aug. 204 23h, 86°; 214 7, 92°; 244 7h, 92°; 304 3h, 98° 
BiFiLar. k=0-0001205. BALANCE. k=0:000014* approximately. 
Aug. 21d 0h—4b. Magnet with short scale in the Declinometer. 
Aug.2ld 7h. Deflection magnet vibrated in the Declinometer box. ‘ 
Aug, 234 0h—24d 6h. Magnet with short scale inserted in the Declinometer box, and the Balance magnet removed, in order to determine its temperature 
rection. The Declination and Bifilar readings are corrected for the effect of the Balance. 
* Aug. 4d 7h. Balance needle vibrated horizontally in the Declinometer box, and afterwards adjusted. 
Ang. 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 bo 
temperature experiments and intensity observations.
