Observed 2" after the Declination. /;=0-0001205. 



Observed 3™ after the Declination. ^i=0-000015 approximately. 



June 224 91> 5m. Discovered several fibres of the Declination suspension thread broken, and, on removing the box cover, the stirrup of the magnet wM fouB 

 resting on the copper ring. The observations of Declination are not given after 21i 22h, as the fibres were probably breaking throughout the day ; the obsernrt™ 

 before 22h are probably attected by a considerable torsion force.
