* June 8* 2'>. When two readings of the torsion circle are given at the same date, the last is the result of a second trial. 

 t June 16* 2''. Three fibres of the suspension thread of the Declinometer found broken ; torsion eliminated as above ; the three fibres 

 *e then withdrawn, and the torsion again removed before 4'^.
