During the Terms of 1842, the Bifilar was observed 2, and the Balance 4", a/ter the corresponding minutes of Declination observation. 
January 204 64, 1842, Discovered some of the fibres of the Declination thread broken and caught on the copper ring; the fibres 
were detached from the ring, but the thread broke away fibre by fibre during the remainder of the term. The observations before 6. 
are corrected by minus 13! in order to make the readings nearly as on other days, the difference being due to torsion force. These obser- 
vations are given here; they are not however considered of much, if of any value, as the fibres were probably breaking throughout the 
whole term.
