BiFlLAli. Observed 2' 



Declination. Magnet untouched, April 14'' 

 after the Declination, A=0-000135. Balance. 



1S46— May 1847. 

 Observed 3™ after the Declination, /t=0-000010. 



.July I'l — 2*. Observations of deflection of the balance needle were made for the purpose of determining the value (*) of a micro- 

 meter division, in parts of the whole vertical force. The observations after July 2* are reduced to be comparable with those before 

 that date. See Introduction, p. xliii. 



t Extra Observations made.
