.Tunc '.".'<1 !>b dm. 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. 1 lie observations of Declination are not given after L'ld. I'll,, as the fibres wore probablv breaking throughout the dav .- the observations 
beloro 22h are probably aneoted by a considerable torsion force.
