Observed 2™ after the Declination. 
Observed 3™ after the Declination. 
June 224 9h 5m. Discovered several fibres of the Declination suspension thread broken, and, on removing the box cover, the stirrup of the magnet was found 
resting on the copper ring. The observations of Declination are not given after 2l¢ 22h, as the fibres were probably breaking throughout the day ; the observations 
before 22h are probably atfected by a considerable torsion force. /
